Patent Description:
In electronic equipment such as a smartphone or a car navigator, a graphical user interface (GUI) can be adopted as an input section to be operated by a user. Examples of the input section include a sensor module having a touch sensor (detection pad). As the sensor module, a sensor module having a capacitive touch sensor is known (see Patent Literature (hereinafter, abbreviated as PTL) <NUM>, for example).

The sensor module described in PTL <NUM> has a touch sensor and a cover member covering at least a part of the touch sensor. This makes it possible to prevent damage on the touch sensor due to contact of an object such as the finger of the user, and detect the contact of the object based on a capacitance change that occurs between the object and the touch sensor when the object comes into contact with the cover member. <CIT> discloses a sensor module, comprising a casing, a contacted section that has conductivity and is disposed inside the casing in an outer recess and a detection section that includes a capacitive detection pad and is disposed inside the casing, wherein the contacted section covered by a package top and a tactile feedback element. <CIT> discloses a touch sensor realised by a parallel-plate capacitor included in wearable display device.

The first liquid crystal lens includes a first liquid crystal layer and a plurality of first control electrodes on the first liquid crystal layer. The sensor is provided on one of the pair of temples and detects a contact position on a detector plane.

However, in the sensor module described in PTL <NUM>, the cover member is disposed between the touch sensor and the object, thereby causing a problem where an amount of change in capacitance caused by the contact of the object is small, resulting in deterioration in sensitivity of the sensor module. Hence there is a room for improvement from the viewpoint of enhancing the sensitivity of the sensor module.

Further, the contacted section is disposed in an outer recess of the casing, wherein at least a part of the contacted section is exposed to an outside of the casing, the detection section includes a through hole and the contacted section is electrically connected to the conductive plate by a first conduction path via the through hole. This enables miniaturization of the sensor module.

A temple according to the present invention is a temple for eyewear, the temple including the sensor module according to the present invention, in which: the casing constitutes an outer shape of the temple, and at least a part of the contacted section is disposed so as to be exposed to an outside of the temple.

According to the present invention, it is possible to provide a sensor module, a temple for eyewear, a frame for eyewear, and eyewear, the sensor module having high sensitivity for contact of the object while preventing damage on a detection pad caused by the contact of the object. Particularly, the sensor module is miniaturized to fit in the temple.

In the following, the term "example" indicates that the respective designated Figures and related description does not belong to the invention in contrast to Figures and related description designated with the term "embodiment".

On one surface (front-side surface) of first substrate <NUM>, diffraction region <NUM> is formed with spherical protrusion <NUM> disposed at the center portion and a plurality of first protruding strips <NUM> in an annular shape arranged on the outside of protrusion <NUM>. The shapes of protrusion <NUM> and first protruding strips <NUM> can be adjusted as appropriate in accordance with the expected optical power at the time of diffracting light incident from the front of electronic glasses <NUM>.

The material for first electrode <NUM> and the material for second electrode <NUM> may be the same as or different from each other.

Liquid crystal layer <NUM> is disposed between first electrode <NUM> and second electrode <NUM>. Liquid crystal layer <NUM> is configured so as to change its refractive index in accordance with application or non-application of the voltage. Although described in detail later, for example, in a state where no voltage is being applied to liquid crystal layer <NUM>, the refractive index of liquid crystal layer <NUM> is almost the same as the refractive index of first substrate <NUM> and the refractive index of second substrate <NUM>, and in a state where the voltage is being applied to liquid crystal layer <NUM>, the refractive index of liquid crystal layer <NUM> can be adjusted so as to be different from the refractive index of first substrate <NUM> and the refractive index of second substrate <NUM>.

Liquid crystal layer <NUM> contains a liquid crystal material. The oriented state of the liquid crystal material at the time when the voltage is being applied and the oriented state of the liquid crystal material at the time when no voltage is being applied are different from each other.

When first electrode <NUM> and second electrode <NUM> are also arranged in second region <NUM>, adhesive layer <NUM> is disposed between first electrode <NUM> and second electrode <NUM>. Adhesive layer <NUM> also has a function to seal the liquid crystal material constituting liquid crystal layer <NUM>.

Adhesive layer <NUM> is made of a hardened material of an adhesive. A material for the adhesive is not particularly limited so long as having expected translucency and being able to appropriately make first substrate <NUM> and second substrate <NUM> adhere to each other. From the viewpoint of adjusting optical power of lens <NUM>, an adhesive having an expected refractive index can be selected.

Lens <NUM> may further have another component having translucency according to the need. Examples of another component include an insulating layer and an oriented film.

The insulating layer prevents conduction between first electrode <NUM> and second electrode <NUM>. For example, the respective insulating layers are disposed between first electrode <NUM> and liquid crystal layer <NUM> and between liquid crystal layer <NUM> and second electrode <NUM>. As a material for the insulating layer, a known material usable as an insulating layer having translucency can be used. Examples of the material for the insulating layer include silicon dioxide.

<FIG> is an exploded view illustrating an example of a configuration of a front end of temple <NUM>. In the following description of temple <NUM> as well, when the "width direction", the "front-rear direction", and the "vertical direction" are mentioned without specific explanation, these mean the respective directions in an opened state (specifically, the state illustrated in <FIG>) where temple <NUM> has opened to front <NUM>. <FIG> is a partial enlarged view of a state in which the front end of temple <NUM> (left-side temple <NUM> in <FIG>) disposed on the right side of the user in a glasses-wearing state (also referred to as one side in the width direction) is seen from the inside in the width direction (a direction of arrow α in <FIG>). <FIG> are partially enlarged perspective views illustrating an example of the configuration of the front end of temple <NUM>. <FIG> is a partially enlarged perspective view illustrating an example of the configuration of the front end of temple <NUM> as seen from the inside in the width direction of electronic glasses <NUM> (the direction of arrow α in <FIG>), and <FIG> is a partially enlarged perspective view illustrating an example of the configuration of the front end of temple <NUM> as seen from the outside in the width direction of electronic glasses <NUM> (a direction of arrow β in <FIG>) <FIG> are partial enlarged views illustrating an example of the configuration of the front end of temple <NUM>. <FIG> is a left-side view (the outer-side view in the width direction) of the front end of temple <NUM>, <FIG> is a right-side view (the inner-side view in the width direction) of the front end of temple <NUM>, and <FIG> is a sectional view cut along a line C-C in <FIG>.

Note that the pair of temples <NUM> are formed so as to be almost symmetrical in electronic glasses <NUM> and have components being the same as each other. Therefore, in the following, temple <NUM> for the right side (disposed on the right side of the user in the glasses-wearing state) will be described, and components of temple <NUM> for the left side (disposed on the left side of the user in the glasses-wearing state) will be provided with the same numerals as those of components of temple <NUM> for the right side, and the description of temple <NUM> for the left side will be omitted.

As illustrated in <FIG>, <FIG>, <FIG>, and <FIG>, temple <NUM> has casing <NUM>, contacted section <NUM>, spacer <NUM>, elastic member <NUM>, detection section <NUM>, and front-end cover <NUM>. Although described in detail later, detection section <NUM> has capacitive detection pad <NUM>. For example, detection pad <NUM> is an electrode layer, and by detecting the capacitance change of the electrode layer caused by contact with contacted section <NUM>, detection pad <NUM> is connected to a sensing section (not illustrated) that senses the contact with contacted section <NUM>.

As illustrated in <FIG>, temple <NUM> is connected to front <NUM> at the front end thereof. For example, temple <NUM> is rotatably engaged with rim <NUM> of front <NUM>.

Casing <NUM> constitutes the outer shape of temple <NUM>. Casing <NUM> stores a part of contacted section <NUM>, spacer <NUM>, elastic member <NUM>, and detection section <NUM>. Casing <NUM> extends along one direction (specifically, the front-rear direction). In the present example, second protruding strip <NUM> extends along the longitudinal direction of casing <NUM> is formed on the left-side surface of casing <NUM> (also referred to as the outer surface in the width direction of electronic glasses <NUM>) (see <FIG>). Further, a short-directional (in other words, vertical) middle point of the outer surface of casing <NUM> is located on the ridge of second protruding strip <NUM>. The shape of the right-side surface of casing <NUM> (also referred to as the inner surface in the width direction of electronic glasses <NUM>) is a planar shape. Hereinafter, in the description of temple <NUM> and each member constituting temple <NUM>, the outer surface in the width direction of electronic glasses <NUM> is simply referred to as the "outer surface". Meanwhile, in the description of temple <NUM> and each member constituting temple <NUM>, the inner surface in the width direction of electronic glasses <NUM> is simply referred to as the "inner surface. " The surface located on the side of the wearer who is wearing electronic glasses <NUM> can also be referred to as the inner surface, and the surface on the opposite side to the inner surface located on the side of the wearer is located can also be referred to as the outer surface.

First opening <NUM> having an elongated shape along the longitudinal direction of casing <NUM> is formed on the outer surface of the front end of casing <NUM> (see <FIG>). First opening <NUM> is formed on the extended line of the ridge (top) of second protruding strip <NUM>. Further, second opening <NUM> is formed on the front end (front surface) of casing <NUM> (see <FIG>). Note that a third opening (not illustrated) is formed at the rear end (also referred to as the back surface) of casing <NUM>. Power source <NUM> is removably disposed at the third opening (see <FIG>).

A material for casing <NUM> is not particularly limited. As the material for casing <NUM>, a known material being used as a material for the temples of glasses can be used. Examples of the material for casing <NUM> are the same as the examples of the material for front <NUM>. However, in the case of using a metallic material for casing <NUM>, a portion of casing <NUM> is made of nonmetallic material, the portion being located on the periphery of contacted section <NUM> and being in contact (or being able to come into contact) with contacted section <NUM>.

Contacted section <NUM> is a portion with which an object such as the finger of the user of electronic glasses <NUM> can come into contact. Hence at least a part of contacted section <NUM> is disposed so as to be exposed to the outside of casing <NUM>. In the present example, contacted section <NUM> is disposed such that a part of contacted section <NUM> is exposed from first opening <NUM> to the outside (also referred to the outside in the width direction) of casing <NUM>.

The position of contacted section <NUM> is preferably positioned such that the user of electronic glasses <NUM> easily touch contacted section <NUM>. From such a perspective, contacted section <NUM> is preferably disposed on the front side of a middle point in a longitudinal direction of casing <NUM>, and more preferably disposed in the foremost-side portion when casing <NUM> is divided into three in the longitudinal direction of casing <NUM>. Further, contacted section <NUM> is preferably disposed on the extended line of the ridge of second protruding strip <NUM>. Moreover, contacted section <NUM> is preferably disposed in a position corresponding to the outer surface of electronic glasses <NUM>.

The shape of contacted section <NUM> is not particularly limited. In the present example, contacted section <NUM> is extended along the longitudinal direction of casing <NUM>. Contacted section <NUM> has exposed portion <NUM> exposed from first opening <NUM> to the outside of casing <NUM>, and stored portion <NUM> stored inside casing <NUM>. For example, exposed portion <NUM> has the shape of a stick, and stored portion <NUM> has the shape of a plate. Such exposed portion <NUM> is exposed from first opening <NUM> to the outside of casing <NUM> in the width direction.

The contact of the object being a conductor with contacted section <NUM> is electrically transmitted to detection section <NUM>. Contacted section <NUM> has conductivity from the viewpoint of electrically connecting between contacted section <NUM> and detection section <NUM>. Examples of a material for contacted section <NUM> include gold, silver, copper, aluminum, iron, and an alloy of these.

The size of contacted section <NUM> can be determined in accordance with the size of casing <NUM>, the size of elastic member <NUM>, and the size of detection pad <NUM> in detection section <NUM>. For example, the length of contacted section <NUM> in the longitudinal direction of casing <NUM> is smaller than the length of the detection region of detection pad <NUM> in the longitudinal direction of casing <NUM>.

<FIG> is a perspective view for explaining an example of positional relationship of spacer <NUM>, elastic member <NUM>, and detection section <NUM>. Spacer <NUM> is disposed between contacted section <NUM> and detection section <NUM>. In the present example, spacer <NUM> is disposed between contacted section <NUM> and conductive plate <NUM> to be described later. In other words, contacted section <NUM>, spacer <NUM>, and detection section <NUM> (specifically, conductive plate <NUM>) are disposed in order from the outside in the width direction. Spacer <NUM> has insulating properties. The shape and size of spacer <NUM> are not particularly limited so long as an appropriate space corresponding to the size of elastic member <NUM> can be formed. In the present example, spacer <NUM> is a plate-like member, at the center of which through hole <NUM> having a rectangular columnar shape is formed.

Elastic member <NUM> has elasticity and conductivity. Elastic member <NUM> is disposed between contacted section <NUM> and detection section <NUM> so as to electrically connect between contacted section <NUM> and detection section <NUM> and urge contacted section <NUM> to the outside (specifically, the outside in the width direction) of casing <NUM>. Thereby, elastic member <NUM> can electrically connect between contacted section <NUM> and detection section <NUM> in an appropriate manner while preventing positional displacement of contacted section <NUM>. In the present example, elastic member <NUM> is disposed so as to abut on the center of contacted section <NUM> in through hole <NUM> of spacer <NUM>. More specifically, a part of elastic member <NUM> is disposed in through hole <NUM> of spacer <NUM>.

Elastic member <NUM> may only be able to exert the above function. In the present example, elastic member <NUM> is a flat spring. Elastic member <NUM> has conductivity from the viewpoint of electrically connecting between contacted section <NUM> and detection section <NUM>. Examples of a material for elastic member <NUM> include gold, silver, copper, aluminum, iron, and an alloy of these.

<FIG> are schematic views for explaining the configuration of detection section <NUM>. <FIG> is a schematic view for explaining the outline of the configuration of detection section <NUM>, and <FIG> is a schematic view for explaining a detailed configuration of detection section <NUM>.

Detection section <NUM> is disposed inside casing <NUM>. In detection section <NUM>, a capacitance change occurs caused by contact between the object and contacted section <NUM>. As illustrated in <FIG>, detection section <NUM> has detecting laminate <NUM>, insulating layer <NUM>, conductive plate <NUM>, and first ground portion <NUM> in order from the inside in the width direction (the lower side in <FIG>).

Although described in detail later, detecting laminate <NUM> has capacitive detection pad <NUM>. Detecting laminate <NUM> detects a capacitance change that occurs due to the contact between the object and contacted section <NUM>.

Insulating layer <NUM> is disposed on detecting laminate <NUM>. More specifically, insulating layer <NUM> is disposed on the detection region of detection pad <NUM> and prevents conduction between detection pad <NUM> and conductive plate <NUM>. Here, the detection region of detection pad <NUM> means a region in which the capacitance change can occur when the object comes into direct contact with detection pad <NUM>.

The configuration of insulating layer <NUM> is not particularly limited so long as having the above function. Insulating layer <NUM> may be made of an insulator or may be an air layer. Insulating layer <NUM> may have a single-layer structure or a laminated structure. Examples of a material for the insulator include silicon dioxide and silicon nitride. In the present example, insulating layer <NUM> is the insulator. Both end faces of insulating layer <NUM> are bonded to detection pad <NUM> and conductive plate <NUM>, respectively. Specifically, the outer surface (the upper surface in <FIG>) of insulating layer <NUM> is bonded to conductive plate <NUM>. Meanwhile, the inner surface (the lower surface in <FIG>) of insulating layer <NUM> is bonded to detection pad <NUM>.

Conductive plate <NUM> is disposed on insulating layer <NUM> (in other words, the outer surface of insulating layer <NUM>). More specifically, conductive plate <NUM> is disposed so as to face the detection region of detection pad <NUM> with insulating layer <NUM> placed therebetween. In the present example, conductive plate <NUM> is disposed on the side closer to contacted section <NUM> (in other words, the outside in the width direction) than detecting laminate <NUM> (specifically, detection pad <NUM>) to be described later. Such conductive plate <NUM> is electrically connected to contacted section <NUM> via elastic member <NUM>. Thus, when the object comes into contact with contacted section <NUM>, a capacitance change occurs between conductive plate <NUM> and detection pad <NUM>.

The size of conductive plate <NUM> is preferably similar to the size of the detection region of detection pad <NUM>. This makes it possible to detect the contact between the object and contacted section <NUM> in a wide region of detection pad <NUM> and enhance the sensitivity to detect the contact of the object. For example, the ratio of the size of the surface of conductive plate <NUM>, which corresponds to the detection region, to the size of the surface of the detection region, is preferably from <NUM> to <NUM>.

First ground portion <NUM> is disposed in a plane including conductive plate <NUM> so as to surround conductive plate <NUM>. First ground portion <NUM> is electrically connected to second ground portion <NUM> (described later). First ground portion <NUM> can release static electricity, generated in conductive plate <NUM> by application from contacted section <NUM>. It is thereby possible to prevent destruction, malfunction, and the like of equipment caused by the static electricity.

Detecting laminate <NUM> will be described here. As illustrated in <FIG>, detecting laminate <NUM> has substrate <NUM>, second ground portion <NUM>, detection pad <NUM>, and third ground section <NUM> in order from the inside in the width direction (the lower side in <FIG>). Insulating layer <NUM> insulates detecting laminate <NUM> from conductive plate <NUM>. Therefore, malfunction due to electric disturbance can be prevented in detecting laminate <NUM>.

Substrate <NUM> is a member for supporting each component of detecting laminate <NUM>. Substrate <NUM> is, for example, a printed circuit board on which control section <NUM> is mounted. Control section <NUM> is connected to detection pad <NUM> so as to receive results of detection of a capacitance change in detection pad <NUM>. In the present example, in detection section <NUM>, substrate <NUM> is disposed inside in the width direction from conductive plate <NUM>, insulating layer <NUM>, and detection pad <NUM>. In other words, conductive plate <NUM>, insulating layer <NUM>, and detection pad <NUM> are disposed between substrate <NUM> and contacted section <NUM>.

Second ground portion <NUM> is disposed between substrate <NUM> and detection pad <NUM>. Second ground portion <NUM> protects detection pad <NUM> from noise. This can prevent an unexpected capacitance change. From the viewpoint of reducing a parasitic capacitance between detection pad <NUM> and second ground portion <NUM>, second ground portion <NUM> preferably has the shape of mesh.

Detection pad <NUM> is a capacitive detection pad that detects a capacitance change caused by the contact between the object and contacted section <NUM>. As detection pad <NUM>, a known detection pad usable as a touch sensor can be used.

Third ground section <NUM> is disposed in a plane including detection pad <NUM> so as to surround detection pad <NUM>. Third ground section <NUM> is electrically connected to second ground portion <NUM>. Third ground section <NUM> protects detection pad <NUM> from noise. This can prevent an unexpected capacitance change.

Front-end cover <NUM> is disposed so as to cover second opening <NUM> of temple <NUM> at the front end of temple <NUM>. At this time, front-end cover <NUM> abuts on one end (front end) of spacer <NUM> and one end (front end) of detection section <NUM> in the longitudinal direction of casing <NUM> (see <FIG> and <FIG>). This makes it possible to fix the positions of spacer <NUM> and detection section <NUM>. Note that front-end cover <NUM> may only be disposed so as to abut on one end (front end) of spacer <NUM> and one end (front end) of detection section <NUM>, and to cover second opening <NUM> of temple <NUM>, and does not need to close all second opening <NUM>.

Control section <NUM> is electrically connected to detection pad <NUM> of detection section <NUM> and the electrode (each of first electrode <NUM> and second electrode <NUM>) of lens <NUM>. When detection section <NUM> detects the contact between the object and contacted section <NUM>, control section <NUM> applies the voltage to each of the pair of lenses <NUM> or stops applying the voltage to each of the pair of lenses <NUM>, to vary the focal length (power) of first region <NUM>) (see <FIG>). Control section <NUM> has a control circuit that controls, for example, driving of detection pad <NUM>, detection of a capacitance change in detection pad <NUM>, and application of the voltage to first region <NUM> of lens <NUM>. Control section <NUM> is mounted on substrate <NUM> of detection section <NUM>, for example.

Power source <NUM> supplies electric power to detection section <NUM> and control section <NUM> (see <FIG>). In the present example, power source <NUM> is a rechargeable battery pack removably held in the other end (the third opening provided at the rear end) of temple <NUM>. Examples of power source <NUM> include a nickel-metal hydride battery.

Subsequently, an example of the operation of electronic glasses <NUM> will be described. First, a state (off-state) where no voltage is being applied to liquid crystal layer <NUM> of electronic glasses <NUM> will be described. In the off-state, in first region <NUM> of lens <NUM>, the refractive index of liquid crystal layer <NUM> and the refractive index of each of first substrate <NUM> and second substrate <NUM> are almost the same. There thus occurs no lens effect attributable to liquid crystal layer <NUM>. Therefore, in lens <NUM>, the focal length (power) of first region <NUM> and the focal length (power) of second region <NUM> are almost the same as each other.

When the object being the conductor (for example, the finger of the user) comes into contact with contacted section <NUM>, detection pad <NUM> of detection section <NUM> detects a capacitance change based on the contact. The detection result of the contact is transmitted to control section <NUM>. When sensing the contact with contacted section <NUM> in the off-state, control section <NUM> applies the voltage to first region <NUM> of lens <NUM>. Thereby, the orientation of the liquid crystal material in liquid crystal layer <NUM> changes, and the refractive index of liquid crystal layer <NUM> changes (on-state). In the on-state, the refractive index of liquid crystal layer <NUM> and the refractive index of each of first substrate <NUM> and second substrate <NUM> are different from each other. Hence the lens effect attributable to liquid crystal layer <NUM> occurs in first region <NUM>. Therefore, the focal length (power) of first region <NUM> can be changed.

In the on-state, when the object comes into contact with contacted section <NUM>, the detection result of the contact is transmitted to control section <NUM> in the same manner as above. When sensing the contact with contacted section <NUM> in the on-state, control section <NUM> stops applying the voltage to first region <NUM> of lens <NUM>. Thereby, the orientation of the liquid crystal material in liquid crystal layer <NUM> returns to the state before the application of the voltage, and the refractive index of liquid crystal layer <NUM> also returns to the state before the application of the voltage (off-state).

As described above, in electronic glasses <NUM> according to the present example, it is possible to vary the focal length of first region <NUM> in lens <NUM> by the contact of the object with contacted section <NUM>.

Electronic glasses <NUM> according to the present example has contacted section <NUM> having conductivity and detection section <NUM>. Contacted section <NUM> is connected to detection section <NUM> (conductive plate <NUM> in the present example) so that a capacitance change that occurs due to the contact with the object occurs in detection pad <NUM>. As compared with a conventional touch sensor pad having the detection region of detection pad covered with the cover member, in electronic glasses <NUM> according to the present example, at least a part of contacted section <NUM> is disposed so as to be exposed to the outside of casing <NUM>. Hence a capacitance change in detection pad <NUM> is large when the object comes into contact with contacted section <NUM>, whereby the contact of the object can be detected with high sensitivity.

In electronic glasses and a frame according to Example <NUM>, only a configuration of temple <NUM> is different from that of temple <NUM> according to Example <NUM>. Therefore, only temple <NUM> will be described and the description of the same components as the components of the electronic glasses and the frame according to Example <NUM> will be omitted while the same numerals as in Example <NUM> will be provided.

<FIG> is an exploded view illustrating an example of the configuration of temple <NUM>. <FIG> is a partial enlarged view illustrating the front end of temple <NUM> as seen from the inside of the electronic glasses according to Example <NUM>. <FIG> are partial enlarged views illustrating an example of the configuration of the front end of temple <NUM>. <FIG> is a left-side view (the outer-side view in the width direction) of the front end of temple <NUM>, <FIG> is a right-side view (the inner-side view in the width direction) of the front of temple <NUM>, and <FIG> is a sectional view cut along a line C-C in <FIG>.

Note that the pair of temples <NUM> are formed so as to be almost symmetrical in the electronic glasses and have components being the same as each other. Therefore, in the following, temple <NUM> for the right side will be described, and the description of the components of temple <NUM> for the left side will be omitted.

As illustrated in <FIG> and <FIG>, temple <NUM> has casing <NUM>, contacted section <NUM>, elastic member <NUM>, detection section <NUM>, and front-end cover <NUM>. Temple <NUM> is connected to front <NUM> at the front end thereof. For example, temple <NUM> is rotatably engaged with rim <NUM> of front <NUM>.

Contacted section <NUM> is a portion with which the object such as the finger of the user of electronic glasses can come into contact. Hence at least a part of contacted section <NUM> is disposed so as to be exposed to the outside of casing <NUM>. In the present example, contacted section <NUM> is disposed such that a part of contacted section <NUM> is exposed from first opening <NUM> to the outside (in other words, the outside in the width direction) of casing <NUM>.

In the present example, contacted section <NUM> has exposed portion <NUM> and stored portion <NUM> stored inside casing <NUM>. For example, stored portion <NUM> has the shape of a plate. In the present example, recess <NUM> is formed on the surface of contacted section <NUM>, the surface being located inside casing <NUM> (the front surface of stored portion <NUM>). Note that contacted section <NUM> is similar to contacted section <NUM> in Example <NUM> except that recess <NUM> is formed on the front surface of stored portion <NUM>.

At least a part of elastic member <NUM> is disposed in recess <NUM>. The shape and size of recess <NUM> are not particularly limited so long as an appropriate space corresponding to the size of elastic member <NUM> can be formed. In the present example, recess <NUM> is a recess having a rectangular columnar shape and formed at the center of stored portion <NUM> in contacted section <NUM>.

Elastic member <NUM> has elasticity and conductivity. Elastic member <NUM> is disposed between contacted section <NUM> and detection section <NUM> so as to electrically connect between contacted section <NUM> and detection section <NUM> and urge contacted section <NUM> to the outside of casing <NUM> (specifically, the outside in the width direction). Thereby, elastic member <NUM> can electrically connect between contacted section <NUM> and detection section <NUM> appropriately while preventing positional displacement of contacted section <NUM>. In the present example, elastic member <NUM> is disposed so as to abut on the center of contacted section <NUM> in recess <NUM> of contacted section <NUM>. More specifically, a part of elastic member <NUM> is disposed in recess <NUM>.

Elastic member <NUM> may only be able to exert the above function. In the present example, elastic member <NUM> is a coil spring. Elastic member <NUM> may be disposed such that the axial direction of the coil spring extends along the front surface of stored portion <NUM>, or may be disposed such that the axial direction of the coil spring is orthogonal to the front surface of stored portion <NUM>. From the viewpoint of increasing the contact area between contacted section <NUM> and elastic member <NUM> and the contact area between elastic member <NUM> and detection section <NUM>, elastic member <NUM> is preferably disposed such that the axial direction of the coil spring extends along the front surface of stored portion <NUM>. Elastic member <NUM> has conductivity from the viewpoint of electrically connecting between contacted section <NUM> and detection section <NUM>. Examples of a material for elastic member <NUM> are the same as those for elastic member <NUM> of Example <NUM>.

The electronic glasses, the frame, and temple <NUM> according to Example <NUM> also have similar effects to those of Example <NUM>. In temple <NUM> according to Example <NUM>, recess <NUM> is formed on the surface of contacted section <NUM>, the surface being located inside casing <NUM> (the front surface of stored portion <NUM>), and at least a part of elastic member <NUM> is disposed in recess <NUM>, whereby a spacer (see Example <NUM>) does not need to be provided between contacted section <NUM> and detection section <NUM>. As thus described, in Example <NUM>, the number of parts of temple <NUM> can be reduced.

<FIG> is an exploded view illustrating an example of the configuration of temple <NUM>. <FIG> is a partial enlarged view illustrating the front end of temple <NUM> as seen from the inside of the electronic glasses according to Example <NUM>. <FIG> are partial enlarged views illustrating an example of the configuration of the front end of temple <NUM>. <FIG> is a left-side view (the outer-side view in the width direction) of the front end of temple <NUM>, <FIG> is a right-side view (the inner-side view in the width direction) of the front end of temple <NUM>, and <FIG> is a sectional view cut along a line C-C in <FIG>.

Note that the pair of temples <NUM> are formed so as to be almost symmetrical in the electronic glasses and have components being the same as each other. Therefore, in the following, temple <NUM> for right side will be described, and the description of the components of temple <NUM> for left side will be omitted.

As illustrated in <FIG> and <FIG>, temple <NUM> has casing <NUM>, contacted section <NUM>, detection section <NUM>, and front-end cover <NUM>. Temple <NUM> is connected to front <NUM> at the front end thereof. For example, temple <NUM> is rotatably engaged with rim <NUM> of front <NUM>.

Contacted section <NUM> has exposed portion <NUM>, stored portion <NUM>, and a fixed portion (holding section) <NUM> fixed to a part of stored portion <NUM>. Fixed portion <NUM> is electrically connected to contacted section <NUM> and detection section <NUM> by abutting on detection section <NUM> (specifically, conductive plate <NUM>). Further, based on the elastic force of its own, fixed portion <NUM> urges exposed portion <NUM> and stored portion <NUM> of contacted section <NUM> to the outside (specifically, the outside in the width direction) of casing <NUM>. That is, fixed portion <NUM> has a similar function to those of elastic members <NUM>, <NUM> of Examples <NUM> and <NUM> described above. Note that contacted section <NUM> is similar to contacted section <NUM> in Example <NUM> except for having fixed portion <NUM>.

In the present example, in an assembled state (the state illustrated in <FIG>), fixed portion <NUM> has elasticity in the outward direction (specifically, the outside in the width direction) of casing <NUM> and functions as the holding section for holding the position of contacted section <NUM>. The shape and size of fixed portion <NUM> are not particularly limited so long as the above function can be obtained. In the present example, fixed portion <NUM> has a flat-spring structure.

Specifically, the base end of fixed portion <NUM> is fixed to the inner surface of stored portion <NUM> in the width direction. Meanwhile, the tip of fixed portion <NUM> is a free end not fixed to the other portion. Fixed portion <NUM> as thus described is inclined such that the tip end is located on the inside in the width direction from the base end in a free state (the state illustrated in <FIG>). While being in contact with conductive plate <NUM> of detection section <NUM>, fixed portion <NUM> can hold a position of contacted section <NUM> (exposed portion <NUM>) by the elastic force of the flat-spring structure. Relative positional displacement between contacted section <NUM> and conductive plate <NUM> is allowable by fixed portion <NUM> of contacted section <NUM> having the flat-spring structure. This ensures the contact between contacted section <NUM> and conductive plate <NUM>.

Contacted section <NUM> moves to the inside (specifically, the inside in the width direction) of casing <NUM> when pressed by the object. Before and after contacted section <NUM> moves to the inside of casing <NUM>, fixed portion <NUM> is constantly in contact with conductive plate <NUM> of detection section <NUM> due to the elastic force of flat-spring structure of fixed portion <NUM>. Hence the contact of the object being the conductor with contacted section <NUM> is electrically transmitted to detection section <NUM>. Contacted section <NUM> has conductivity from the viewpoint of electrically connecting between contacted section <NUM> and detection section <NUM>. Examples of a material for contacted section <NUM> are the same as those for contacted section <NUM> of Example <NUM>.

The electronic glasses, the frame, and temple <NUM> according to Embodiment <NUM> also have similar effects to those of Example <NUM>. In Example <NUM>, contacted section <NUM> itself has elasticity. That is, contacted section <NUM> has fixed portion <NUM> with a similar function to those of elastic members <NUM>, <NUM> of Embodiments <NUM> and <NUM> described above. For this reason, temple <NUM> does not need to have an elastic member (see Examples <NUM> and <NUM>) between contacted section <NUM> and detection section <NUM>. As thus described, in Example <NUM>, the number of parts of temple <NUM> can be reduced.

In electronic glasses and a frame according to Example <NUM>, only a configuration of temple <NUM> is different from that of temple <NUM> according to Example1. Therefore, only temple <NUM> will be described and the description of the same components as the components of the electronic glasses and the frame according to Example <NUM> will be omitted while the same numerals as in Example1 will be provided.

<FIG> is an exploded view illustrating an example of the configuration of temple <NUM>. <FIG> is a partial enlarged view of a state in which the front end of the electronic glasses according to Example <NUM> is seen from the inside in the width direction (a direction of arrow α in <FIG>). <FIG> are partially enlarged perspective views illustrating an example of the configuration of the front end of temple <NUM>. <FIG> is a partially enlarged perspective view illustrating an example of the configuration of the front end of temple <NUM> as seen from the inside in the width direction of the electronic glasses (the direction of arrow α in <FIG>), and <FIG> is a partially enlarged perspective view illustrating an example of the configuration of the front end of temple <NUM> as seen from the outside in the width direction of the electronic glasses (a direction of arrow β in <FIG>). <FIG> are partial enlarged views illustrating an example of the configuration of the front end of temple <NUM>. <FIG> is a left-side view (outer-side view) of the front end of temple <NUM>, <FIG> is a right-side view (inner-side view) of the front of temple <NUM>, and <FIG> is a sectional view cut along a line C-C in <FIG>.

As illustrated in <FIG>, <FIG>, <FIG>, and <FIG>, temple <NUM> has casing <NUM>, three contacted sections <NUM>, spacer <NUM>, three elastic members <NUM>, detection section <NUM>, and front-end cover <NUM>. Temple <NUM> is connected to front <NUM> at the front end thereof. For example, temple <NUM> is rotatably engaged with rim <NUM> of front <NUM>.

Casing <NUM> constitutes the outer shape of temple <NUM>. Casing <NUM> stores a part of each of three contacted sections <NUM>, spacer <NUM>, three elastic members <NUM>, and detection section <NUM>. Three first openings <NUM> each having an elongated shape along the longitudinal direction of casing <NUM> is formed on the left-side surface (outer surface) of the front end of casing <NUM> (see <FIG>). Note that casing <NUM> is similar to casing <NUM> in Example <NUM> except that the number of first openings <NUM> is three.

In Example <NUM>, three contacted sections <NUM> are disposed such that a part of each contacted section <NUM> is exposed from each of three first openings <NUM> to the outside (specifically, the outside in the width direction) of casing <NUM>. The interval between adjacent contacted sections <NUM> (in other words, first openings <NUM>) are not particularly limited, but can be adjusted as appropriate according to the need.

The shapes and sizes of three contacted sections <NUM> may be the same as or different from each other. In the present example, the shapes and sizes of three contacted sections <NUM> are the same as each other.

Spacer <NUM> is disposed between three contacted sections <NUM> and detection section <NUM>. Spacer <NUM> has insulating properties. The shape and size of spacer <NUM> are not particularly limited so long as an appropriate space corresponding to the size of elastic member <NUM> can be formed. In the present example, spacer <NUM> is a plate-like member with three through holes <NUM> each having a rectangular columnar shape formed therein.

Three elastic members <NUM> have elasticity and conductivity. Three elastic members <NUM> are disposed so as to abut on three contacted sections <NUM> and detection section <NUM> (specifically, three conductive plates <NUM> to be described later), respectively, in through hole <NUM> of spacer <NUM>. Three elastic members <NUM> may be the same as or different from each other. In the present example, three elastic members <NUM> are the same as each other.

In the present example, each of three contacted sections <NUM> is connected to detection section <NUM> via elastic member <NUM> so that a capacitance change caused by the contact between the object and contacted section <NUM> occurs in detection pad <NUM>. That is, three contacted sections <NUM> are each connected to one detection section <NUM> in an electrically independent manner. In the present example, the number of conductive plates <NUM> is three. More specifically, three conductive plates <NUM> are disposed so as to face different regions in the detection region of detection pad <NUM>. Detection pad <NUM> has a position awareness function and can thus distinguish and become aware of contacted section <NUM> to which the object has contacted based on the position where the capacitance change occurs in detection pad <NUM>.

The electronic glasses, the frame, and temple <NUM> according to Example <NUM> also have similar effects to those of Example <NUM>. In Example <NUM>, temple <NUM> has three contacted sections <NUM> and three elastic members <NUM>. Therefore, in the present example, the flexibility in design of the electronic glasses can be enhanced. For example, three contacted sections <NUM> can be used as switches configured to switch various functions in the electronic glasses in a mutually independent manner.

In Example <NUM> above, temple <NUM> having three contacted sections <NUM>, three elastic members <NUM>, and one detection section <NUM> has been described, but the numbers of the respective components are not particularly limited, but can be adjusted as appropriate according to the need. For example, the number of detection sections (the number of elastic members) may be the same as the number of contacted sections.

In electronic glasses and a frame according to Embodiment <NUM>, only a configuration of temple <NUM> is different from that of temple <NUM> according to Example <NUM>. Therefore, only temple <NUM> will be described and the description of the same components as the components of the electronic glasses and the frame according to Example <NUM> will be omitted while the same numerals as in Example <NUM> will be provided.

Embodiment <NUM> will be described below with reference to <FIG>. In the following description as well, when the "width direction", the "front-rear direction", and the "vertical direction" are mentioned without specific explanation, these mean the respective directions of electronic glasses <NUM> in an opened state (the state illustrated in <FIG>) where the user can wear electronic glasses <NUM> as glasses.

In the following, the structure of one temple <NUM> of a pair of temples <NUM> (for example, temple <NUM> disposed on the right side of the user in the glasses wearing state) will be described. The structure of the other temple <NUM> (disposed on the left side of the user in the glasses wearing state) may have a structure almost symmetrical to one temple <NUM> or different from one temple <NUM>.

As illustrated in <FIG> and <FIG>, temple <NUM> has casing <NUM>, contacted section <NUM>, detection section <NUM>, light source <NUM>, light guiding member <NUM>, side cover <NUM>, adhesive member <NUM>, and front-end cover <NUM>. Hereinafter, each member constituting temple <NUM> will be described.

Casing <NUM> constitutes the outer shape of temple <NUM> as illustrated in <FIG>. Casing <NUM> has storage space 541e (see <FIG>) that stores detection section <NUM>. Casing <NUM> extends along one direction (specifically, the front-rear direction). Specifically, casing <NUM> has outer wall 541a provided outside in the width direction, and inner wall 541b disposed on the inside in the width direction (the lower side in <FIG>) from outer wall 541a and facing outer wall 541a in the width direction.

In the present embodiment, second protruding strip <NUM> extending along the longitudinal direction of casing <NUM> is formed on the outer surface of outer wall 541a of casing <NUM> (see <FIG>). Further, a short-directional (also referred to as vertical) middle point of the outer surface of outer wall 541a is located on the ridge of second protruding strip <NUM>. The inner surface of inner wall 541b is a flat surface.

The upper end of outer wall 541a and the upper end of inner wall 541b are made continuous in the width direction by upper wall 541c. Meanwhile, the lower end of outer wall 541a and the lower end of inner wall 541b are made continuous in the width direction by lower wall 541d. A space surrounded by outer wall 541a, inner wall 541b, upper wall 541c, and lower wall 541d is storage space 541e of casing <NUM>.

Outer wall 541a has outer recess 541f on the outer surface. Outer recess 541f has a substantially hexagonal shape as seen from the outside in the width direction. Outer recess 541f has outer through hole <NUM> at the bottom. Outer through hole <NUM> penetrates outer wall 541a from the bottom of outer recess 541f to the inner surface of outer wall 541a. Outer connection member 501A of connection member <NUM> to be described later is inserted into outer through hole <NUM> as thus described.

Inner wall 541b has inner recess <NUM> on the inner surface. Inner recess <NUM> has a long oval shape being long in the longitudinal direction (also referred to as the front-rear direction) of casing <NUM> as seen from the inside in the width direction. At least a part of such inner recess <NUM> overlaps in the width direction with outer recess 541f of outer wall 541a.

Inner recess <NUM> has first inner through hole 541i at the bottom. First inner through hole 541i penetrates inner wall 541b from the bottom of inner recess <NUM> to the outer surface (the top surface in <FIG>) of inner wall 541b. A part of light guiding body 503a of light guiding member <NUM> to be described later is inserted into first inner through hole 541i as thus described.

Inner recess <NUM> has second inner through hole 541j in a position away from first inner through hole 541i. Second inner through hole 541j penetrates from the bottom of inner recess <NUM> to the outer surface (the top surface in <FIG>) of inner wall 541b. At least a part of second inner through hole 541j overlaps in the width direction with outer through hole <NUM> of outer wall 541a. In the present embodiment, the central axis of second inner through hole 541j coincides with the central axis of outer through hole <NUM>.

Second inner through hole 541j has an inner diameter large enough to allow passage of inner connection member 501B of connection member <NUM> to be described later from the inside in the width direction to the outside in the width direction (from the lower side to the upper side in <FIG>). Further, second inner through hole 541j has an inner diameter large enough to allow insertion of a tool (not illustrated) for engaging (screwing, in the present embodiment) inner connection member 501B with outer connection member 501A of connection member <NUM>. In an assembled state, positioning protrusion 503f of light guiding member <NUM> to be described later is inserted from the inside in the width direction into second inner through hole 541j as thus described.

Casing <NUM> has first guide groove <NUM> and second guide groove <NUM> on the inside surface (see <FIG>, and <FIG>). First guide groove <NUM> and second guide groove <NUM> are guides at the time of disposing substrate <NUM> to be described later in storage space 541e of casing <NUM>.

Specifically, casing <NUM> has first guide groove <NUM> on the inside surface (also referred to as the lower surface) of upper wall 541c and second guide groove <NUM> on the inside surface (also referred to as the upper surface) of lower wall 541d. Each of First guide groove <NUM> and second guide groove <NUM> extends in the front-rear direction and has the front end opened. The length of each of first guide groove <NUM> and second guide groove <NUM> in the front-rear direction is smaller than the length of substrate <NUM> to be described later in the width direction.

The width of the rear end of each of first guide groove <NUM> and second guide groove <NUM> is smaller than the width of front end. Specifically, first guide groove <NUM> and second guide groove <NUM> each have parallel groove 541n (see <FIG>) that has a constant width in the front-rear direction and inclined groove 541p (see <FIG>) provided in the rear of parallel groove 541n.

The width of inclined groove 541p becomes smaller toward the rear. First guide groove <NUM> and second guide groove <NUM> as thus described are engaged with the short-directional (also referred to as vertical) end of substrate <NUM> (also referred to as the vertical direction) to guide the displacement of substrate <NUM> in the longitudinal direction (also referred to as the front-rear direction).

Contacted section <NUM> is a portion with which the object such as the finger of the user of electronic glasses <NUM> can come into contact. Hence at least a part of contacted section <NUM> is disposed so as to be exposed to the outside of casing <NUM>.

Examples of a material for contacted section <NUM> include a metallic material having conductivity, such as gold, silver, copper, aluminum, iron, and an alloy of these. The contact of the object being a conductor with contacted section <NUM> is electrically transmitted to detection section <NUM> to be described later. Note that a path through which the contact is transmitted will be described later.

According to the invention, contacted section <NUM> is disposed in outer recess 541f. In this state, the outer surface of contacted section <NUM> is exposed to the outside of casing <NUM> in a state where the user's finger can come into contact with the outer surface.

Specifically, the shape of contacted section <NUM> as seen from the outside in the width direction is a substantially hexagonal shape slightly smaller than the outer-edge shape of outer recess 541f as seen from the same direction. At the short-directional center of casing <NUM> on the outer surface, contacted section <NUM> has contacted-section-side protruding strip 542a (see <FIG>, <FIG>, and <FIG>) extending in the longitudinal direction of casing <NUM>.

The outer surface of such contacted section <NUM> is on the same plane with a portion present on the periphery of outer recess 541f on the outer surface of casing <NUM>. However, the outer surface of contacted section <NUM> may protrude outside in the width direction from the portion present on the periphery of outer recess 541f on the outer surface of casing <NUM> (specifically outer wall 541a). The inner surface of contacted section <NUM> abuts on the bottom of outer recess 541f.

The outer surface of contacted section <NUM> is more inclined toward the inside in the width direction (the lower side of each in <FIG>) from contacted-section-side protruding strip 542a to each side of casing <NUM> in the short direction (the lateral direction in each of <FIG>). Outer connection member 501A of connection member <NUM> to be described later is integrally provided with contacted section <NUM> on the inner surface of contacted section <NUM>.

<FIG> is a schematic view for explaining the configuration of detection section <NUM>. Detection section <NUM> is disposed in storage space 541e of casing <NUM> and electrically connected to contacted section <NUM>. In detection section <NUM>, a capacitance change occurs caused by contact between the object and contacted section <NUM>.

Detection section <NUM> has through hole 557A (see <FIG>) penetrating therethrough from the outer surface to the inner surface. Further, detection section <NUM> has, on the inner peripheral surface of through hole 557A, conduction section 558A (see <FIG>) for electric conduction from the outer surface to the inner surface.

Specifically, as illustrated in <FIG>, detection section <NUM> has a laminate structure in which a plurality of layers are laminated. Specifically, detection section <NUM> has outer plate-like member <NUM>, insulating layer 556a, substrate <NUM> (first substrate 551a, insulating layer 556b, second substrate 551b), insulating layer 556c, second ground portion <NUM>, insulating layer 556d, detection pad <NUM>, insulating layer 556e, and conductive plate <NUM> in order from the outside in the width direction (the upper side in <FIG>).

In the present embodiment, outer plate-like member <NUM>, insulating layer 556a, first substrate 551a, insulating layer 556b, second substrate 551b, insulating layer 556c, second ground portion <NUM>, insulating layer 556d, and detection pad <NUM> constitute detecting laminate <NUM>. Detecting laminate <NUM> detects a capacitance change that occurs due to the contact between the object and contacted section <NUM>. For example, detection pad <NUM> is an electrode layer, and by detecting the capacitance change of the electrode layer caused by the contact with contacted section <NUM>, detection pad <NUM> is connected to a sensing section (not illustrated) that senses the contact with contacted section <NUM>.

Outer plate-like member <NUM> is plate-like member made of, for example, metal, ceramics, synthetic resin, or the like. Outer plate-like member <NUM> has through-hole element 557a penetrating therethrough from the outer surface to the inner surface. At the peripheral edge of through-hole element 557a, outer plate-like member <NUM> has annular conduction section 558a along the peripheral edge. Conduction section 558a is made of metal having conductivity, such as gold, silver, or copper.

Conduction section 558a has outer conduction section 555a (see <FIG>) disposed on the outer surface of outer plate-like member <NUM>. Outer conduction section 555a abuts on the tip surface (the inner end face in the width direction) of outer connection member 501A to be described later. In the present embodiment, the outer diameter of outer conduction section 555a is larger than the outer diameter of the tip surface of outer connection member 501A.

With such a configuration, the tip surface of outer connection member 501A reliably abuts on outer conduction section 555a. As a result, electrical connection is reliably made between outer connection member 501A and conduction section 558a. On the other hand, in conduction section 558a, a portion disposed on the inner surface of outer plate-like member <NUM> is continued to conduction section 558b of insulating layer 556a.

Each of insulating layers 556a to 556e is made of an insulator. Insulating layers 556a to 556e may have a single-layer structure or a laminated structure. Examples of a material for each of insulating layers 556a to 556e include silicon dioxide and silicon nitride. Insulating layers 556a to 556e respectively have through-hole elements 557b to 557f penetrating therethrough in the width direction.

At the peripheral edges of through-hole elements 557b to 557f, insulating layers 556a to 556e have annular conduction sections 558b to 558f along the peripheral edges. Conduction sections 558b to 558f are made of metal having conductivity, such as gold, silver, or copper.

Substrate <NUM> has first substrate 551a, insulating layer 556b, and second substrate 551b in order from the outside in the width direction. Such substrate <NUM> supports each element constituting detection section <NUM>. Substrate <NUM> is, for example, a printed circuit board on which control section <NUM> (see <FIG>) is mounted. In the case of the present embodiment as well, control section <NUM> is connected to detection pad <NUM> so as to receive results of detection of a capacitance change in detection pad <NUM>.

In the present embodiment, in detection section <NUM>, substrate <NUM> is disposed outside in the width direction (the upper side in <FIG>) from conductive plate <NUM>, insulating layer 556e, and detection pad <NUM>.

First substrate 551a and second substrate 551b respectively have through-hole elements <NUM>, <NUM> penetrating therethrough in the width direction. At the peripheral edges of through-hole elements <NUM>, <NUM>, first substrate 551a and second substrate 551b respectively have annular conduction section <NUM>, <NUM> along the peripheral edges. Each of conduction section <NUM>, <NUM> is made of metal having conductivity, such as gold, silver, or copper.

Second ground portion <NUM> is disposed between substrate <NUM> and detection pad <NUM> via insulating layers 556c, 556d. Second ground portion <NUM> protects detection pad <NUM> from noise. This can prevent an unexpected capacitance change. In the case of the present embodiment as well, from the viewpoint of reducing a parasitic capacitance between detection pad <NUM> and second ground portion <NUM>, second ground portion <NUM> preferably has the shape of mesh.

Second ground portion <NUM> has through-hole element 557i penetrating therethrough in the width direction. At the peripheral edge of through-hole element 557i, second ground portion <NUM> has annular conduction section 558i along the peripheral edge. Conduction section 558i is made of metal having conductivity, such as gold, silver, or copper.

Similarly to Example <NUM> described above, detection pad <NUM> is a capacitive detection pad that detects a capacitance change caused by contact between the object and contacted section <NUM>. As detection pad <NUM>, a known detection pad usable as a touch sensor can be used.

Detection pad <NUM> has through-hole element 557j penetrating therethrough in the width direction. At the peripheral edge of through-hole element 557j, detection pad <NUM> has annular conduction section 558j along the peripheral edge. Conduction section 558j is made of metal having conductivity, such as gold, silver, or copper. In detection pad <NUM>, conduction section 558j is not connected to detection region 553a (see <FIG>) present on the periphery of conduction section 558j.

Conductive plate <NUM> is disposed on the inner surface of insulating layer 556e in the width direction. Specifically, conductive plate <NUM> is disposed so as to face detection region 553a of detection pad <NUM> with insulating layer 556e placed therebetween. In the present embodiment, conductive plate <NUM> is disposed in a position more distant from contacted section <NUM> than detecting laminate <NUM> (specifically, detection pad <NUM>).

Conductive plate <NUM> has through-hole element <NUM> penetrating therethrough in the width direction. At the peripheral edge of through-hole element <NUM>, conductive plate <NUM> has annular conduction section <NUM> along the peripheral edge. Conduction section <NUM> is made of metal having conductivity, such as gold, silver, or copper.

Conduction section <NUM> has inner conduction section 548a (see <FIG>) disposed on the inner surface of conductive plate <NUM> in the width direction. Inner conduction section 548a abuts on head 501b of inner connection member 501B (also referred to as a grasping section; see <FIG>).

In the present embodiment, the outer diameter of inner conduction section 548a is larger than the outer diameter of head 501b of inner connection member 501B. With this configuration, head 501b of inner connection member 501B reliably abuts on inner conduction section 548a. As a result, electrical connection is reliably made between inner connection member 501B and conduction section <NUM>.

In a state where the respective members constituting detection section <NUM> as described above are laminated in the width direction, the central axes of through-hole elements 557a to <NUM> are located on the same axis. Through-hole elements 557a to <NUM> constitute through hole 557A of detection section <NUM>.

Such through hole 557A penetrates detection section <NUM> from the outer surface (also referred to as a first surface) thereof to the inner surface (also referred to as a second surface) thereof. In the present embodiment, the outer surface of detection section <NUM> is the outer surface of outer plate-like member <NUM>. Meanwhile, the inner surface of detection section <NUM> is the inner surface of conductive plate <NUM>.

The conduction sections that are adjacent in the width direction among conduction sections 558A to <NUM> are electrically connected to each other. In this manner, electrical connection is made between conduction section 558a disposed on the outermost side in the width direction and conduction section <NUM> disposed on the innermost side in the width direction. Conduction sections 558A to <NUM> constitute conduction section 558A of detection section <NUM>.

Connection member <NUM> has conductivity and electrically connects between contacted section <NUM> and detection section <NUM>. Connection member <NUM> fixes contacted section <NUM> and substrate <NUM> of detection section <NUM>. In the present embodiment, contacted section <NUM> and detection section <NUM> are electrically connected via a first conduction path and a second conduction path to be described later.

Specifically, connection member <NUM> has outer connection member 501A and inner connection member 501B. Outer connection member 501A is a fastening part such as a nut and provided on the inner surface of contacted section <NUM>. Outer connection member 501A is a cylindrical member with its tip side (the lower side in <FIG>) opened, and has female threaded section 501a (see <FIG>) on at least a part of inner peripheral surface.

The base end (the top end in <FIG>) of outer connection member 501A is integrally fixed to the inner surface of contacted section <NUM>. Such outer connection member 501A is inserted into outer through hole <NUM> of casing <NUM> from the outside in the width direction.

In this state, the tip surface of outer connection member 501A abuts on a first end (the outer end in the width direction, and the upper end in <FIG>) of conduction section 558A of detection section <NUM>. Specifically, the tip surface of outer connection member 501A abuts on outer conduction section 555a of outer plate-like member <NUM> in detection section <NUM>.

Inner connection member 501B is a fastening part such as a screw or a bolt. Inner connection member 501B has head 501b and axial portion 501c. Head 501b has engagement portion 501d, with which a tool such as a driver or a hex wrench can be engaged, on one end face in the axial direction (the lower end face in <FIG>).

The outer shape of head 501b is a circular shape, for example. The outer shape of head 501b may be a polygonal shape such as a hexagonal shape. In this case, engagement portion 501d of head 501b may be omitted.

Axial portion 501c is a solid axial member and has male threaded section 501e (see <FIG>) on the outer peripheral surface. Axial portion 501c has an outer diameter small enough to be inserted into through hole 557A of detection section <NUM>. Such axial portion 501c is inserted into through hole 557A of detection section <NUM> from the inside in the width direction.

In this state, male threaded section 501e of axial portion 501c is engaged with female threaded section 501a of outer connection member 501A. Thereby, outer connection member 501A and inner connection member 501B are fastened and connected electrically.

With outer connection member 501A and inner connection member 501B in the fastened state, head 501b of inner connection member 501B abuts on a second end (the inner end in the width direction, and the lower end in <FIG>) of conduction section 558A of detection section <NUM>. Specifically, head 501b of inner connection member 501B abuts on inner conduction section 548a of conductive plate <NUM> in detection section <NUM>, from the inside in the width direction.

As described above, outer connection member 501A abuts on the first end of conduction section 558A of detection section <NUM> and inner connection member 501B abuts on the second end of conduction section 558A of detection section <NUM>, whereby contacted section <NUM> and conductive plate <NUM> of detection section <NUM> are conducted by the first conduction path and the second conduction path to be described below.

In the present embodiment, conductive plate <NUM> is electrically connected to contacted section <NUM> via the first conduction path on the outer surface (also referred to as a first main surface) side. Meanwhile, conductive plate <NUM> is electrically connected to contacted section <NUM> via the second conduction path on the inner surface (also referred to as a second main surface) side.

The first conduction path is a path that connects between contacted section <NUM> and conductive plate <NUM> of detection section <NUM> via through hole 557A. Specifically, first conduction path is made up of contacted section <NUM>, outer connection member 501A, conduction section 558A of detection section <NUM>, and conductive plate <NUM>, in the order presented.

Meanwhile, the second conduction path is a path that connects between contacted section <NUM> and conductive plate <NUM> of detection section <NUM> via connection member <NUM> (specifically, the engagement section of outer connection member 501A and inner connection member 501B). Specifically, second conduction path is made up of contacted section <NUM>, outer connection member 501A, inner connection member 501B, and conductive plate <NUM>, in the order presented.

Light source <NUM> (see <FIG>) emits light in a light emission pattern corresponding to the state of electronic glasses <NUM>. Light source <NUM> emits light (is turned on) in a state where electronic glasses <NUM> are being operated (on-state), and is turned off in a state where electronic glasses <NUM> are not operated (off-state).

Light source <NUM> is, for example, a light emitting diode (LED). Such light source <NUM> is supported on substrate <NUM>. Specifically, in the present embodiment, light source <NUM> is provided in a position of the inner surface (the bottom surface in <FIG>) of substrate <NUM>, the position overlapping in the width direction with first inner through hole 541i of casing <NUM>.

Light guiding member <NUM> has optical transparency and guides the light from light source <NUM> to the outside of casing <NUM>. That is, the user and the like can view the light from light source <NUM> from the outside via light guiding member <NUM>. Such light guiding member <NUM> is made of resin such as acryl, polycarbonate, polystyrene, and a composite material of these.

Specifically, as illustrated in <FIG>, light guiding member <NUM> has light guiding body 503a, support section 503b, and positioning protrusion 503f. Light guiding body 503a is a portion that guides the light from light source <NUM> to the outside of casing <NUM> and has a solid cylindrical shape. Light guiding body 503a is disposed such that its axial direction coincides with the width direction of electronic glasses <NUM> in an opened state (the state illustrated in <FIG>).

A first end (the lower end in <FIG>, and also referred to as one end in the axial direction) of light guiding body 503a is disposed in exposure through hole 504a of side cover <NUM>. The first end face (the lower end face in <FIG>) of light guiding body 503a is exposed to the outside from exposure through hole 504a of side cover <NUM> to be described later.

Meanwhile, a second end (the upper end in <FIG>, and also referred to the other end in the axial direction) of light guiding body 503a is inserted into first inner through hole 541i of inner recess <NUM> in casing <NUM>.

In this state, the second end face (the upper end face in <FIG>) of light guiding body 503a faces light source <NUM>. The light from light source <NUM> is incident on light guiding body 503a from the second end face of light guiding body 503a and goes outside from the first end face of light guiding body 503a.

Support section 503b supports light guiding body 503a with respect to casing <NUM>. Support section 503b is a plate-like member and provided on the outer peripheral surface of light guiding body 503a. Such support section 503b is disposed in inner recess <NUM> of casing <NUM>. Specifically, support section 503b has first covering section 503c, second covering section 503d, and continuous section 503e.

First covering section 503c extends from the outer peripheral surface of light guiding body 503a to the outer side in the radial direction of light guiding body 503a. Specifically, first covering section 503c is a ring-shaped plate member and has an outer diameter larger than the outer diameter of first inner through hole 541i. The inner peripheral edge of first covering section 503c is integrally fixed to the outer peripheral surface of light guiding body 503a.

Such first covering section 503c abuts on the periphery of first inner through hole 541i at the bottom of inner recess <NUM>. First covering section 503c thus covers a first opening (the lower opening in <FIG>) of a clearance (specifically, a cylindrical clearance) between the inner peripheral surface of first inner through hole 541i and the outer peripheral surface of light guiding body 503a.

In the present embodiment, first covering section 503c closes the whole circumference of the first opening of the clearance. Thereby, a liquid such as water hardly enters first inner through hole 541i from the outside.

Second covering section 503d is continued to first covering section 503c via continuous section 503e. Second covering section 503d is a disk-shaped plate member and has an outer diameter larger than the outer diameter of second inner through hole 541j.

Such second covering section 503d covers the first opening (the lower opening in <FIG>) of second inner through hole 541j. In the present embodiment, second covering section 503d closes the entire first opening of second inner through hole 541j. Thereby, a liquid such as water hardly enters second inner through hole 541j from the outside.

Positioning protrusion 503f is integrally provided on the outer surface (the top surface in <FIG>) of second covering section 503d. Positioning protrusion 503f is a solid cylindrical member and protrudes from the outer surface of second covering section 503d.

Positioning protrusion 503f has an inner diameter slightly smaller than the inner diameter of second inner through hole 541j. Such positioning protrusion 503f is inserted into second inner through hole 541j. The rotational movement of Light guiding member <NUM> is prevented by engagement between positioning protrusion 503f and second inner through hole 541j.

Side cover <NUM> is a plate-like member having a light blocking effect. Side cover <NUM> has exposure through hole 504a (also referred to as a light transmissive section) that exposes the first end face (the lower end face in <FIG>) of light guiding body 503a to the outside. In casing <NUM>, exposure through hole 504a is provided in a position overlapping first inner through hole 541i in the width direction. Note that a light transmissive section is not limited to the through hole of the present embodiment so long as allowing passage of light guided by light guiding member <NUM>. For example, the light transmissive section may be a member having translucency (for example, a resin member having translucency), provided in a part of side cover <NUM>.

Such side cover <NUM> is disposed on the inside in the width direction (the lower side in <FIG>) from support section 503b of light guiding member <NUM> in inner recess <NUM> of casing <NUM>. Side cover <NUM> may be fixed to inner recess <NUM> of casing <NUM> by adhesive member <NUM> to be described later.

In this state, the first end (the lower end in <FIG>) of light guiding body 503a is inserted into exposure through hole 504a. In this manner, the first end face of light guiding body 503a is exposed to the outside via exposure through hole 504a.

Identification information 504b (see <FIG> and <FIG>) such as a logo mark is added to the inner surface of side cover <NUM>. Identification information 504b is formed on the inner surface of side cover <NUM> by, for example, laser processing, marking, printing, or the like. The inner surface of side cover <NUM> is present on the same plane as the inner side surface of casing <NUM> (specifically, inner wall 541b).

Adhesive member <NUM> is disposed between the bottom of inner recess <NUM> of casing <NUM> and side cover <NUM> to fix side cover <NUM> to the bottom of inner recess <NUM>. Adhesive member <NUM> is, for example, a double-sided tape, and has storage section 505a (see <FIG> and <FIG>) in which support section 503b of light guiding member <NUM> can be disposed.

In the present embodiment, storage section 505a is a through hole. Storage section 505a has a size large enough to accept second inner through hole 541j of casing <NUM>, first inner through hole 541i of casing <NUM>, and exposure through hole 504a of side cover <NUM>, on the inside of the outer peripheral edge of storage section 505a as seen from the width direction. In other words, in the width direction, storage section 505a overlaps each of second inner through hole 541j, first inner through hole 541i, and exposure through hole 504a. The shape of storage section 505a is not particularly limited so long as being a shape in which support section 503b of light guiding member <NUM> can be disposed. Support section 503b of light guiding member <NUM> is disposed in storage section 505a as thus described.

Front-end cover <NUM> (see <FIG> and <FIG>) is disposed so as to cover second opening <NUM> of temple <NUM> at the front end of temple <NUM>. Such front-end cover <NUM> is a box-shaped member with its rear end side opened.

Specifically, front-end cover <NUM> has front wall 546e that closes tubular portion 546A having a rectangular cross section and the front opening of tubular portion 546A. Tubular portion 546A is made up of first wall 546a and second wall 546b that face the width direction, and third wall 546c and fourth wall 546d that face the vertical direction.

Each of third wall 546c and fourth wall 546d has, on the rear end face, positioning recess 546f, positioning step <NUM>, and positioning protrusion <NUM> in order from the inside in the width direction (the lower side in <FIG>, <FIG>).

Tubular portion 546A is inserted into second opening <NUM> of temple <NUM> in an assembled state (the state illustrated in <FIG> and <FIG>). In this state, the front end of substrate <NUM> abuts on positioning recess 546f and positioning step <NUM>.

In this manner, the forward positioning and outward positioning of substrate <NUM> in the width direction are performed. Note that the rearward positioning of substrate <NUM> is performed by engagement between the rear end of substrate <NUM> and the inside surface of casing <NUM>. Further, the inward positioning of substrate <NUM> in the width direction is performed by engagement between contacted section <NUM>, fixed to substrate <NUM> via connection member <NUM>, and outer recess 541f of casing <NUM>.

Front wall 546e has positioning flange 546i extending inward in the width direction from tubular portion 546A (specifically, second wall 546b). Such positioning flange 546i abuts on the front end on inner wall 541b of casing <NUM>.

The rearward positioning of front-end cover <NUM> with respect to casing <NUM> is thereby performed. Note that the positioning of front-end cover <NUM> in the width and vertical directions is performed by engagement between tubular portion 546A and the inside surface of casing <NUM>.

Front wall 546e has through hole 546j for a flexible printed circuit (FPC) that allows insertion of FPC <NUM> (see <FIG> and <FIG>) connected to substrate <NUM>. Further, front wall 546e has, on the front-side surface, guide surface <NUM> that is smoothly inclined rearward from the outside to the inside in the width direction.

Guide surface <NUM> guides temple <NUM> for smooth rotational movement with respect to each end of front <NUM> in the width direction. Guide surface <NUM> is formed by combination of curves and straight lines. Such a shape of guide surface <NUM> is determined as appropriate corresponding to the shapes of each end of front <NUM> in the width direction.

Hereinafter, an assembly procedure for temple <NUM> will be described. First, as illustrated in <FIG>, substrate <NUM> is inserted from second opening <NUM> of casing <NUM> into storage space 541e. At this time, the short-directional end (specifically, the vertical end) of substrate <NUM> is engaged with first guide groove <NUM> and second guide groove <NUM> of casing <NUM> to guide insertion of substrate <NUM>.

Next, contacted section <NUM> is disposed in outer recess 541f of casing <NUM>. At this time, outer connection member 501A provided integrally with contacted section <NUM> is inserted into outer through hole <NUM> of casing <NUM>. Next, inner connection member 501B is led into storage space 541e from second inner through hole 541j in casing <NUM>.

Next, axial portion 501c of inner connection member 501B is inserted into through hole 557A of detection section <NUM>. Then, male threaded section 501e of inner connection member 501B is engaged (screwed) with female threaded section 501a of outer connection member 501A. At this time, inner connection member 501B is rotated using a tool (not illustrated) such as a driver led into storage space 541e from second inner through hole 541j in casing <NUM>.

Subsequently, light guiding body 503a of light guiding member <NUM> is inserted into first inner through hole 541i of casing <NUM>, and positioning protrusion 503f of light guiding member <NUM> is inserted into second inner through hole 541j of casing <NUM>. In this state, first covering section 503c of light guiding member <NUM> covers the entire first opening (the lower opening in <FIG>) of the clearance between the inner peripheral surface of first inner through hole 541i of casing <NUM> and the outer peripheral surface of light guiding body 503a.

Meanwhile, in the state described above, second covering section 503d of light guiding member <NUM> covers the entire first opening (the lower opening in <FIG>) of second inner through hole 541j. Next, adhesive member <NUM> is caused to adhere to the bottom of inner recess <NUM> of casing <NUM>. In this state (the state illustrated in <FIG>), support section 503b of light guiding member <NUM> is disposed inside storage section 505a of adhesive member <NUM>.

Then, side cover <NUM> is bonded to adhesive member <NUM> so as to be disposed in inner recess <NUM> of casing <NUM>. In this state (the state illustrated in <FIG>), the first end face in the axial direction (the lower end face in <FIG>) of light guiding body 503a is disposed in exposure through hole 504a of side cover <NUM>.

The electronic glasses, the frame, and temple <NUM> according to Embodiment <NUM> also have similar effects to those of Example <NUM>. Further, in the case of Embodiment <NUM>, even when a structure is formed where substrate <NUM> is disposed between conductive plate <NUM> and contacted section <NUM>, conductive plate <NUM> and contacted section <NUM> can be electrically connected by connection member <NUM>.

Especially in the case of the present embodiment, conductive plate <NUM> and contacted section <NUM> are electrically connected by two paths being the first conduction path and the second conduction path. This enables stable detection of the contact of the object with contacted section <NUM>. As a result, it is possible to ensure the stability of the operation of the electronic glasses.

The summary of the sensor module according to the present invention as described above includes: a casing; a contacted section that has conductivity and is disposed such that at least a part of the contacted section is exposed to an outside of the casing; and a detection section that has a capacitive detection pad and is disposed inside the casing, and in the sensor module, the contacted section is connected to the detection section so that a capacitance change caused by contact with the object occurs in the detection pad.

In Examples <NUM> to <NUM> above, detection section <NUM> having detecting laminate <NUM>, insulating layer <NUM>, conductive plate <NUM>, and first ground portion <NUM> has been described, but the detection section of the sensor module does not need to have insulating layer <NUM>, conductive plate <NUM>, or first ground portion <NUM>. In this case, the contacted section and the detection pad in the detection section are connected directly or electrically to each other via an elastic member.

In Examples <NUM> to <NUM> above, the electronic glasses having the pair of temples according to the present invention have been described, but the frame and the eyewear according to the present invention are not limited to this aspect. For example, one temple may be made up only of a casing.

In Examples1 to <NUM> above, the electronic glasses have been described as the eyewear, but the eyewear according to the present invention is not limited to the electronic glasses. Other examples of the eyewear include sunglasses and goggles.
