BEST MODE FOR CARRYING OUT INVENTION
Hereinafter, a connector cover for a mobile type electronic device, and the mobile type electronic device will be described in detail in the exemplary embodiment of the present invention. Further, an unit with the same function in each figure has a common sign each other.
FIG. 3 is a perspective view showing the connector cover for the mobile type electronic devices in a first exemplary embodiment of the present invention and showing an example of the connector cover for the cellular phone which has a slide structure.
FIG. 4 and FIG. 5 show an usage mode of the mobile type electronic device equipped with the connector cover for the mobile type electronic device in the first exemplary embodiment of the present invention.
In FIG. 3, signs 101, 102, 103, 104, and 105 denote a cellular phone, a chassis of the cellular phone 101, a cover member which is a component of the connector cover, a display unit, and a corner at which a plurality of surfaces of the chassis intersect respectively (sign 105 is attached to two corners at which two surfaces intersect in FIG. 3.).
As shown in FIG. 4 and FIG. 5, a connector 201 is arranged so as to be exposed on the chassis 102 and in the case that the connector 201 is not used, the connector 201 is in a state to be covered by the cover member 103 thereof.
The connector cover has a structure that the cover member 103 can rotate over the chassis 102 with a rotation axis of a support member (not shown in the figure). Consequently, it is possible that the cover member 103 moves between a position to cover the connector 201 and a position to expose the connector 201.
The cover member 103 is made of a non-slip member which has a predetermined friction coefficient. As a raw material for the cover member 103, for example, rubber or elastomer is suitable.
The display 104 displays the television image and the moving picture.
In the case that the cellular phone 101 leans against a corner of a wall 202 or the like for watching television, the cellular phone 101 leans so that the display 104 may face to a user and the cover member 103 may touch the floor and the wall 202, as shown in FIG. 4.
The cellular phone 101 enters into a stationary state in which the cellular phone 101 holds an inclination angle requested by a user, since the cover member 103, which has difficulty in slipping on the floor and the wall 202 owing to characteristics of rubber or the like, touches the floor and the wall 202. Then, the user can enjoy viewing an image displayed by the display unit 104 from a direction of an arrow A side.
On the other hand, in the case that the cellular phone 101 does not use the corner, any surrounding object is used as a support object 301 (any object can be used as the support object, if the object has a predetermined size). In this case, the support object 301 is arranged on the floor 202, and the cellular phone 101 is set so that one cover member 101 touches the floor 202 and an edge of the other cover member 103 touches the support object 301, as shown in FIG. 5.
Since each of cover members 103 has a predetermined thickness so that the cover member 103 projects to the outside from the surface of the chassis 102, the cover member 103 can be arranged so that the edge of the cover member 103 can touch the support object 301 surely.
Moreover, the cover member 103 can be hung on the support object 301. In this case, the cellular phone 101 is held at the predetermined angle by the support object 301 and then, the cellular phone 101 enters into the stationary state. So, a user can enjoy viewing the image, which is displayed by the display unit 104, from the direction of arrow A side.
As described above, according to the connector cover for the mobile type electronic device, and the mobile type electronic device of the exemplary embodiment of the present invention, since the cover member 103 is made of the non-slip member and is arranged at the corner 105, at which two surfaces of the chassis 102 intersect, so as to cover the connector 201 over a plurality of surfaces, it is possible to hold surely the inclination angle, at which a user can watch the television image and the moving picture comfortably, without the dedicated cradle or the dedicated tilt leg.
Here, through making the cover member 103 project by the predetermined height from the designed surface of the chassis 102 to make a shape of the cover member 103 convex, it is possible to make the cover member 103 touch the support object 301 more surely and consequently, more effect is obtained.
Moreover, since the cover which is used for the connector or the like and which is made of rubber or the like, is arranged at the corner 105, the cover has a function to prevent slipping and consequently, it is possible to hold surely the inclination angle which is required at a time when the cellular phone 101 leans against the surrounding object and the image displayed by the display unit 104 is watched etc. In the case of the cellular phone 101 or the like, since it is general that the cellular phone 101 or the like is equipped with the connector cover for the connector 201, it is possible to hold the inclination angle without increasing number of the components.
FIG. 6 is a perspective view showing a connector cover for a mobile type electronic device in a second exemplary embodiment of the present invention and shows an example of the connector cover for the cellular phone which has the slide structure.
FIG. 7 shows an usage mode of the mobile type electronic device equipped with the connector cover for the mobile type electronic device in the second exemplary embodiment of the present invention.
While the case of watching the image on the landscape-oriented screen is exemplified in the first exemplary embodiment, a case of watching the image on a portrait-oriented screen is exemplified in the second exemplary embodiment.
The second exemplary embodiment of the present invention also has similar effect that it is possible to hold surely the inclination angle, at which a user can watch the television image and the moving picture comfortably, without the dedicated cradle or the dedicated tilt leg as the effect of the first exemplary embodiment of the present invention.
FIG. 8 shows a connector cover for the mobile type electronic device in a third exemplary embodiment of the present invention and is a side view showing a usage mode of the mobile type electronic device (cellular phone 101 which has the slide structure is exemplified also in the third exemplary embodiment of the present invention.) equipped with the connector cover.
While the thickness of the cover member 103 is made approximately uniform in the first and the second exemplary embodiments of the present invention, each of cover members 601 has an outer side 602 which is opposite to the corner 105 of the chassis 102 of the mobile type electronic device and which is formed flatly in the third exemplary embodiment of the present invention. As a result, since a contact area of each of the cover members 601 with the floor and the wall 202 becomes large and a friction of the cover member 601 against the floor and the wall 202 becomes large and then, the cellular phone 101 can be held more surely at the desired angle.
FIG. 9 and FIG. 10 show a connector cover for the mobile type electronic device respectively in a fourth exemplary embodiment of the present invention and are side views showing a mobile type electronic device (cellular phone 101 which has the slide structure is exemplified also in the fourth exemplary embodiment) equipped with the connector cover respectively.
While the amount of the projection length of each of plural cover members 103 from the chassis 102 is fixed in the first to the third exemplary embodiments, an amount of projection length of a cover member 701 can be changed in the fourth exemplary embodiment.
The connector cover includes the cover member 701 and a pin 702 which is formed to be unified with the cover member 701. The pin 702 can move in a direction, which is indicated by an arrow B along a ditch (not shown in the figure) formed inside the chassis 102, so the cover member 701 slides in the direction which is indicated by the arrow B along the ditch. The cover member 701 is held stably both at a first position shown in FIG. 9 and at a second position shown in FIG. 10 by virtue of a detente structure which is not shown in the figures.
In the case of the first position, that is, in the case that the cover member 701 is stored in the chassis 102, the cover member 701 is in a state that the cover member 701 projects by the predetermined height from the surface of the chassis 102 as shown in FIG. 9, similarly to the first to the third exemplary embodiments. When the cover member 701 is used in the state, the fourth exemplary embodiment has similar effect of the first and the second embodiments.
Next, in the case that the cover member 701 is drawn out from the chassis 102 in a direction of projection in a state of FIG. 9, the cover member 701 slides by a working of the pin 702 to be held at the second position which projects furthermore as shown in FIG. 10. Thus, through making an amount of projection from the chassis 102 large, it is possible to hold the cellular phone 101 more stably than the case of the usage mode shown in FIG. 5.
While the case that the cellular phone is applied to the mobile type electronic device is described in each of the exemplary embodiments, it is possible that various kinds of mobile electronic devices such as PHS (Personal Handyphone System), a mobile information terminal and a mobile type personal computer are applied.
Moreover, while a plurality of cover members 103, 601 and 701 are arranged at the corner 105 at which two surfaces of the chassis 102 intersect, in each of the exemplary embodiments, it may be preferable that the cover member is arranged at a corner at which three or four surfaces intersect. In other word, it may be preferable that cover members 103, 601 and 701 can be arranged at a corner at which at least two surfaces of the chassis 102 intersect.
Moreover, it may be preferable that the cover members 103, 601 and 701 are arranged on the chassis 102 in full width, full length or full circumference thereof and that the cover member is made of elastomer.
