     DESCRIPTION OF EMBODIMENTS 
     A display device according to an embodiment of the invention will be described with reference to the accompanying drawings. 
     A display device  100  according to the embodiment is a vehicle gauge which is built a vehicle, and the external shape of the display device  100  is shown in  FIG. 1 . 
     As shown in  FIGS. 2(   a ) and  2 ( b ), the display device  100  includes a display unit  10 , a pointer type gauge  20 , a framing unit  30 , a moving mechanism  40 , a circuit substrate  50 , and a case body  60 . 
     Meanwhile, hereinafter, as shown using double arrows in  FIG. 1 , description is made in such a way that the display surface direction of the display device  100  (that is, a user side direction with respect to the display device  100 ) is set to “front”, a direction opposite to the display surface direction is set to “back”, and up, down, left, and right directions acquired when the display surface is viewed by a user who visually recognizes the display surface are set to “up”, “down”, “left”, and “right”, respectively. 
     The display unit  10  is, for example, a Thin Film Transistor (TFT) liquid crystal display unit of 12.3 inches, and displays a vehicle speed, the number of revolutions of an engine, the temperature of the engine, the amount of fuel remaining, various warnings, and the like under the control of a control unit  70  which will be described later. In addition, the display unit  10  changes a display state in accordance with the positional states (a “first pattern”, a “second pattern”, and the like which will be described later) of the pointer type gauge  20  and the framing unit  30  which move in the horizontal direction in a sliding manner (refer to  FIGS. 8(   a ) and  8 ( b )). The movement of the pointer type gauge  20  and the framing unit  30  and the change of the display states performed by the display unit  10  will be described in detail later. 
     The display unit  10  includes a TFT liquid crystal panel, a polarizing plate, backlights, a display housing (not shown in the drawing), and the like, is attached to a fitting member (not shown in the drawing) which is formed in, for example, the case body  60 , and is arranged and supported in a prescribed position. 
     As shown mainly in  FIGS. 2(   b ) and  3 ( b ), the pointer type gauge  20  includes a needle driving part  21 , a first magnet body  22 , a second magnet body  23 , a needle unit  24 , light sources  25 , and a conduction member  26 . Meanwhile, as will be described later, the respective parts which configure the pointer type gauge  20  are attached to a first moving plate  411  directly or through a first component  31  of the framing unit  30  which is attached to the first moving plate  411 . Therefore, the respective members move in accordance with the movement of the first moving plate  411 . 
     The needle driving part  21  includes, for example, a stepping motor, and causes a rotating shaft  21   a  to rotate depending on a measured quantity (for example, vehicle speed) under the control of the control unit  70  which will be described later. As shown in  FIG. 2(   b ), the needle driving part  21  is fixed to a substrate B which is attached to the back surface side of the first moving plate  411  which will be described later. The end portion of the rotating shaft  21   a  passes through a hole Bo which is provided in the substrate B and an opening  411   a  of the first moving plate  411  which will be described later, and is positioned immediately on the back of the display unit  10 . 
     The first magnet body  22  is attached to the rotating shaft  21   a , and rotates in accordance with the rotation of the rotating shaft  21   a . As shown in  FIG. 2(   b ), the first magnet body  22  which is attached as described above is positioned immediately on the back of the display unit  10 . As shown in  FIG. 3(   b ), the first magnet body  22  includes a yoke section  22   a  and a magnet section  22   b  on the side of the rotating shaft  21   a , efficiently transmits magnetic force to the second magnet body  23 , and causes the needle driving part  21  to hardly receive magnetic influence using the magnetic-permeable effect of the yoke section  22   a.    
     The second magnet body  23  is rotatably supported by a pedestal  313  which will be described later, and is positioned in a position which is the front side of the display unit  10  and which is opposite to the first magnet body  22 . The second magnet body  23  receives magnetic force which penetrates through the display unit  10  from the first magnet body  22 , and rotates in accordance with the rotation of the first magnet body  22 . In addition, the second magnet body  23  supports a needle shaft  24   a  of the needle unit  24  which will be described later. 
     The rotative power of the needle driving part  21  is transmitted to the needle unit  24  by the first magnet body  22  and the second magnet body  23 , and thus the needle unit  24  can rotate. It is necessary for the display housing of the above-described display unit  10  to transmit magnetic force as above, and thus the display housing is formed of a non-magnetic material such as aluminum or the like. 
     The needle unit  24  is a needle member which integrally rotates with the second magnet body  23 , and includes the needle shaft  24   a , a light guiding needle  24   b , and a needle cap  24   c , as shown in  FIG. 3(   b ). 
     The needle shaft  24   a  is pivotally supported by the second magnet body  23 . The light guiding needle  24   b  is fixed to the needle shaft  24   a , receives light emitted by the light sources  25  using a light receiving unit (not shown in the drawing) on the side of the needle shaft  24   a , and emits light. The light guiding needle  24   b  is formed of a colorless or colored transparent light guiding material. The needle cap  24   c  is attached to the light guiding needle  24   b  in such a way as to cover a part of the light guiding needle  24   b  (which approaches the needle shaft  24   a ) from the front side of the axis direction of the needle shaft  24   a . The needle cap  24   c  is a black cap which is formed of, for example, a synthetic resin, and does not transmit light. 
     The light sources  25  are provided to be adjacent to the needle shaft  24   a , and includes one or a plurality (for example, 2 or 3 lamps) of Light Emitting Diodes (LEDs). As shown in  FIG. 4(   b ), the light sources  25  are attached to a light source attaching part  311   d  of the framing unit  30 , which will be described later. The attached light sources  25  are positioned directly under the needle unit  24  (back side of the needle cap  24   c ), and illuminate the needle unit  24  (emit light toward the light receiving unit of the light guiding needle  24   b ). The light sources  25  emit light under the control of the control unit  70  which will be described later. 
     As shown in  FIG. 4(   b ), the conduction member  26  includes, for example, a Flexible Printed Circuit (FPC), connects the light sources  25  to the control unit  70  (microcomputer  71 ) which will be described later, and transmits a control signal which is transmitted from the control unit  70  to the light sources  25 . The conduction member  26  is attached to a first substrate  311  which will be described later as shown in the drawing. 
     As shown in  FIG. 4(   a ), the framing unit  30  includes the first component  31  and a second component  32  which independently move in the horizontal direction in a sliding manner by the moving mechanism  40 . 
     As shown in  FIG. 4(   b ), the first component  31  is a component which moves together with the pointer type gauge  20  in a sliding manner, and includes the first substrate  311 , a first framing cover  312 , and the pedestal  313 . 
     The second component  32  is positioned on the right side of the first component  31 , and includes a second substrate  321  and a second framing cover  322  as shown in  FIG. 4(   b ). 
     The first substrate  311  and the second substrate  321  are formed of, for example, a metal material, such as aluminum or stainless steel, and are formed through a press process, a cutting process, and the like. 
     The first substrate  311  includes a circular arc part  311   a , an arm part  311   b , an attaching part  311   c , and a light source attaching part  311   d.    
     The second substrate  321  includes a circular arc part  321   a , an arm part  321   b , and an attaching part  321   c.    
     When the first substrate  311  approaches the second substrate  321  (refer to  FIG. 5(   a )), the circular arc parts  311   a  and  321   a  are formed to be a single circular shape (ring shape). That is, the circular arc part  311   a  of the first substrate  311  is formed to have a left half arc shape and the circular arc part  321   a  of the second substrate  321  is formed to have a right half arc shape based on a line which passes through the center of a circle of the circular shape in the vertical direction (hereinafter, the virtual line is referred to as a reference line). 
     The arm part  311   b  of the first substrate  311  is a member which is formed to extend from a part of the circular arc part  311   a  toward the center of the arc. In the same manner, the arm part  321   b  of the second substrate  321  is a member which is formed to extend from a part of the semicircular arc-shaped circular arc part  321   a  toward the center of the arc. 
     The arm part  311   b  and the arm part  321   b  are formed to be line symmetrical with respect to the reference line. In particular, the arm part  311   b  of the first substrate  311  has a function to guide the conduction member  26  to the light sources  25 . More specifically, the conduction member  26  which has an end that is connected to the control unit  70  is attached along a part of the circular arc part  311   a  and, further, is attached along the arm part  311   b , and thus the other end thereof is provided to reach the light sources  25  as shown in  FIG. 4(   b ). In contrast, the arm part  321   b  of the second substrate  321  is formed as described above in response to a request for design. Therefore, the arm part  321   b  may be omitted. 
     The attaching parts  311   c  of the first substrate  311  are members which are formed to extend in the outer circumferential direction (vertical direction) of the circle from both ends of the circular arc part  311   a , and include mounting holes o1. In the same manner, the attaching parts  321   c  of the second substrate  321  are members which are formed to extend in the outer circumferential direction (vertical direction) of the circle from both ends of the circular arc part  321   a , and include mounting holes o2. 
     When the attaching parts  311   c  of the first substrate  311  are attached and fixed to the first moving plate  411  which will be described later, the first component  31  of the framing unit  30  moves in a sliding manner in accordance with the first moving plate  411  moving in a sliding manner. More specifically, the first component  31  is fixed to the first moving plate  411  using bolts or the like (not shown in the drawing) which pass through the mounting holes o1. In the same manner, when the attaching parts  321   c  of the second substrate  321  are attached and fixed to the second moving plate  421  which will be described later, the second component  32  of the framing unit  30  moves in a sliding manner in accordance with the second moving plate  421  moving in a sliding manner. More specifically, the second component  32  is fixed to the second moving plate  421  using bolts or the like (not shown in the drawing) which pass through the mounting holes o2. The movement in a sliding manner performed by each of the first moving plate  411  and the second moving plate  421  will be described later in detail. 
     The light source attaching part  311   d  is a circular-shaped (ring-shaped) member which is attached to the end of the arm part  311   b . The above-described light sources  25  are attached to the light source attaching part  311   d  along the circular-shaped circumference. The center of the circle of the light source attaching part  311   d  substantially coincides with (including exactly coincides with) the center of a circle which is expressed when the circular arc parts  311   a  and  321   a  approach each other. 
     In the embodiment, the first substrate  311  and the second substrate  321  are formed to be line symmetrical with regard to the reference line except for the light source attaching part  311   d  which is included in the first substrate  311 . 
     Each of the first framing cover  312  and the second framing cover  322  is an impermeable member which is formed of metal, synthetic resins, or the like. As shown in  FIG. 3(   a ), the first framing cover  312  includes a main body part  3120  and a plurality of ribs r1, and the second framing cover  322  includes a main body part  3220  and a plurality of ribs r2. 
     Meanwhile, the ribs r1 and r2 are omitted in the drawings except for in  FIG. 1 ,  FIGS. 3(   a ) to  3 ( c ), and  FIG. 10(   b ). 
     The main body part  3120  of the first framing cover  312  is a member which is formed to correspond to the circular arc part  311   a  and the arm part  311   b  of the first substrate  311  (such that projection regions from the front side have substantially the same shape), and which is attached to the first substrate  311  such that both are covered from the front side. 
     The main body part  3220  of the second framing cover  322  is a member which is formed to correspond to the circular arc part  321   a  and the arm part  321   b  of the second substrate  321  (such that the projection regions from the front side have substantially the same shape), and which is attached to the second substrate  321  such that both are covered from the front side. 
     The plurality of ribs r1 are formed on the surface of the main body part  3120 , and the plurality of ribs r2 are formed on the surface of the main body part  3220 . For example, as shown in  FIG. 3(   a ), the plurality of ribs r1 and r2 are positioned respectively at equivalent intervals along the circumferential direction of the circle which is expressed when the circular arc parts  311   a  and  321   a  approach each other. 
     In the embodiment, the number of ribs r1 and r2 is six in total. However, the ribs r1 and r2 are not assigned equally to the first framing cover  312  and the second framing cover  322 . The first framing cover  312  includes four ribs r1 and the second framing cover  322  includes two ribs r2. In particular, when the first component  31  and the second component  32  approach each other, two ribs r1 (referential numerals are underlined in the drawing), which are positioned in the vertical direction (positioned in the closest positions to the second framing cover  322 ), of four ribs r1 of the first framing cover  312  are provided such that a part thereof wraps the main body part  3220  of the second framing cover  322  (overlaps when the display device  100  is viewed from the front side (viewed straight on)), as shown in  FIG. 3(   c ). When the first component  31  and the second component  32  approach each other, the two ribs r1 which are positioned in the vertical direction do not come into contact with the surface of the main body part  3220  of the second framing cover  322 . 
     In this way, when a ring shape is expressed using the first component  31  and the second component  32  (refer to  FIG. 5(   a )), it is possible to express a smooth ring shape without unintended intermittence (gaps) while both components do not come into contact with each other. In addition, since the ring shape is expressed while both components do not come into contact with each other, it is possible to suppress shock generated during movement, thereby leading to prevention of failure. In addition, impulsive sounds are not generated when both components collide with each other, thereby leading to prevention of noise. 
     In addition, the first framing cover  312  includes an impermeable member and covers the first substrate  311  provided with the conduction member  26  from the front side, and thus it is possible to hide the conduction member  26 . In this manner, it is possible to attach the conduction member  26  such that the conduction member  26  is not viewed by the user. Meanwhile, in the embodiment, the impermeable member is used for the first framing cover  312 . However, a semitransparent member may be used to an extent that the conduction member  26  is unnoticeable. The second framing cover  322  may also be a semitransparent member. 
     As shown in  FIG. 4(   b ), the pedestal  313  is a member which is formed of a predetermined resin in, for example, a circular truncated conical shape, and which rotatably holds the second magnet body  23 , and is attached to the light source attaching part  311   d  of the first substrate  31 . A hollow storage space is formed in the pedestal  313 , and the pedestal  313  rotatably holds and stores the second magnet body  23  using the storage space. A hole part o3 which has an opening diameter larger than a shaft diameter of the needle shaft  24   a  of the needle unit  24  is formed at a central part of the front-side surface (the base of a circular truncated cone) of the pedestal  313 . The needle shaft  24   a  which is pivotally supported by the second magnet body  23  passes through the hole part o3. 
     As shown in  FIG. 2(   b ), the moving mechanism  40  includes a first moving mechanism  41 , a second moving mechanism  42 , a slide mechanism  43 , and a moving mechanism housing  44 . 
     The first moving mechanism  41  is a mechanism to cause the first component  31  of the framing unit  30  (and the pointer type gauge  20 ) to move in the horizontal direction in a sliding manner. 
     The second moving mechanism  42  is a mechanism to cause the second component  32  of the framing unit  30  to move in the horizontal direction in a sliding manner. 
     The first moving mechanism  41  includes a first moving plate  411 , a first driving part  412 , a first transmission mechanism  413 , and a first detecting unit  414 . 
     The second moving mechanism  42  includes a second moving plate  421 , a second driving part  422 , a second transmission mechanism  423 , and a second detecting unit  424 . 
     The first moving plate  411  and the second moving plate  421  are members which are formed of, for example, a non-magnetic metal such as a resin material, aluminum, or the like. 
     The first moving plate  411  holds the pointer type gauge  20  and the first component  31  of the framing unit  30 . In addition, the first moving plate  411  is attached to a timing belt  413   c  of the first transmission mechanism  413 , which will be described later, through a sandwiched part n1 which is formed on the back surface thereof. An opening  411   a  is provided in the first moving plate  411  in order to cause the rotating shaft  21   a  of the needle driving part  21  to pass therethrough. The opening  411   a  is provided on the back surface side of the first moving plate  411  from the circumference, and a substrate attaching part C is formed (the substrate attaching part C may be a different body from the first moving plate  411 ). The above-described substrate B is attached to the substrate attaching part C, and the needle driving part  21  is attached to the substrate B, and thus the needle driving part  21  is fixed to the back side of the first moving plate  411 . 
     The second moving plate  421  holds the second component  32  of the framing unit  30 . In addition, the second moving plate  421  is attached to a timing belt  423   c  of the second transmission mechanism  423 , which will be described later, through a sandwiched part n2 which is formed on the back surface thereof. 
     Each of the first driving part  412  and the second driving part  422  includes, for example, a stepping motor. The first driving part  412  causes the rotating shaft  412   a  to rotate under the control of the control unit  70  which will be described later. In the same manner, the second driving part  422  causes the rotating shaft  422   a  to rotate under the control of the control unit  70  which will be described later. The second driving part  422  is positioned above the first driving part  412  as shown in  FIGS. 1 and 2(   b ). 
     The first transmission mechanism  413  and the second transmission mechanism  423  are arranged at a predetermined interval from each other in the vertical direction. When both are arranged in this manner, it is possible to prevent the display device  100  from being thick in the front and back directions. Therefore, the display device  100  can be thin. The first transmission mechanism  413  is positioned on the lower side of the second transmission mechanism  423 . 
     The first transmission mechanism  413  includes two pulleys  413   a  and  413   b  which are arranged at a predetermined interval in the horizontal direction, and the timing belt  413   c  which is wound up by both the pulleys. As shown in  FIG. 1 , the pulley  413   a  is positioned on the right side when viewed from the front side of the display device  100 , is press-fitted by the rotating shaft  412   a  of the first driving part  412  (may be fastened through a gear), and rotates in accordance with the rotation of the rotating shaft  412   a . As shown in  FIG. 1 , the pulley  413   b  is positioned on the left side when viewed from the front side of the display device  100 , and is rotatably held by an axis A1 (refer to  FIG. 1 ) which is attached to the moving mechanism housing  44 . The timing belt  413   c  is attached with predetermined tension such that the two pulleys  413   a  and  413   b  are not idle. Therefore, if the pulley  413   a  rotates, the pulley  413   b  also rotates in the same manner. In this manner, the first transmission mechanism  413  converts rotation power which is generated by the first driving part  412  into power in the slide direction (horizontal direction), thereby causing the first moving plate  411  which is attached to the timing belt  413   c  to move in a sliding manner, as described above. 
     The second transmission mechanism  423  includes two pulleys  423   a  and  423   b  which are arranged at a predetermined interval in the horizontal direction, and the timing belt  423   c  which is wound up by both the pulleys. As shown in  FIG. 1 , the pulley  423   a  is positioned on the right side when viewed from the front side of the display device  100 , is press-fitted by the rotating shaft  422   a  of the second driving part  422  (may be fastened through a gear), and rotates in accordance with the rotation of the rotating shaft  422   a . As shown in  FIG. 1 , the pulley  423   b  is positioned on the left side when viewed from the front side of the display device  100 , and is rotatably held by an axis A2 (refer to  FIGS. 1 and 2(   a )) which is attached to the moving mechanism housing  44 . The timing belt  423   c  is attached with predetermined tension such that the two pulleys  423   a  and  423   b  are not idle. Therefore, if the pulley  423   a  rotates, the pulley  423   b  also rotates in the same manner. In this manner, the second transmission mechanism  423  converts rotation power which is generated by the second driving part  422  into power in the sliding direction (horizontal direction), thereby causing the second moving plate  421  which is attached to the timing belt  423   c  to move in a sliding manner, as described above. 
     The first detecting unit  414 , which is schematically shown in  FIGS. 5(   a ) and  5 ( b ), is used to detect the position of the first component  31  of the framing unit  30 , includes, for example, a photoreflector (reflection type photo interrupter), and includes a first detecting part  414   a  and a first detection target  414   b . In the same manner, the second detecting unit  424  is used to detect the position of the second component  32  of the framing unit  30 , includes, for example, a photoreflector (reflection type photo interrupter), and includes a second detecting part  424   a  and a second detection target  424   b.    
     The first detecting part  414   a  includes a light emitting element (infrared LED) which emits, for example, infrared light and a light receiving element (phototransistor), and supplies a detection signal to the control unit  70  which will be described later when the first detection target  414   b  is detected. The first detection target  414   b  is a reflection part which reflects, for example, infrared light, and is a detection target part of the first detecting part  414   a . More specifically, if the first detecting part  414   a  which irradiates infrared light is positioned in a position facing the first detection target  414   b , the first detection target  414   b  reflects infrared light which is emitted by the light emitting element of the first detecting part  414   a  toward the first detecting part  414   a . Further, the first detecting part  414   a  detects the first detection target  414   b  by receiving the reflected light using the light receiving element, and supplies the detection signal to the control unit  70  through a sensor information input port  82 . 
     The first detecting part  414   a  is attached to a predetermined position of the first moving plate  411 . The first detection target  414   b  is used to determine the movement completion position of the first component  31 . A plurality of first detection targets  414   b  are attached to positions which do not move like the first moving plate  411  (for example, predetermined positions of the moving mechanism housing  44 ). More specifically, as schematically shown in  FIG. 5 , for example, three first detection targets  414   b  are respectively arranged at predetermined intervals in the horizontal direction. The first detecting part  414   a  and the first detection targets  414   b  are respectively arranged at the same height in the vertical direction of the display device  100 . If the first moving plate  411  moves in a sliding manner and the first detecting part  414   a  goes to a position facing any of the plurality of first detection targets  414   b , the first detecting part  414   a  reacts thereto and detects that the first moving plate  411  is positioned in a prescribed position (that is, the first component  31  is present in the movement completion position). In this manner, the first detecting unit  414  detects the position of the first component  31  of the framing unit  30 . 
     The second detecting part  424   a  includes a light emitting element (infrared LED) which emits, for example, infrared light and a light receiving element (phototransistor), and supplies a detection signal to the control unit  70  which will be described later when the second detection target  424   b  is detected. The second detection target  424   b  is a reflection part which reflects, for example, infrared light, and is the detection target part of the second detecting part  424   a . A structure in which the second detecting part  424   a  detects the second detection target  424   b  is the same as that of the first detecting unit  414 . 
     The second detecting part  424   a  is attached to a predetermined position of the second moving plate  421 . The second detection target  424   b  is used to determine the movement completion position of the second component  32 . A plurality of second detection targets  424   b  are attached to positions which do not move like the second moving plate  421  (for example, predetermined positions of the moving mechanism housing  44 ). More specifically, as schematically shown in  FIG. 5 , for example, the three second detection targets  424   b  are respectively arranged at predetermined intervals in the horizontal direction. The second detecting part  424   a  and the second detection targets  424   b  are respectively arranged at the same height in the vertical direction of the display device  100 . If the second moving plate  421  moves in a sliding manner and the second detecting part  424   a  goes to a position facing any of the plurality of second detection targets  424   b , the second detecting part  424   a  reacts thereto and detects that the second moving plate  421  is positioned in a prescribed position (that is, the second component  32  is present in the movement completion position). In this manner, the second detecting unit  424  detects the position of the second component  32  of the framing unit  30 . 
     The first moving plate  411  and the second moving plate  421  stop (complete movement) based on the provision positions of the first detection target  414   b  and the second detection target  424   b . Therefore, when each of the parts which are included in the first transmission mechanism  413  and the second transmission mechanism  423  expands and contracts due to change in temperature or is worn down, it is possible to perform accurate movement without deviation of positions acquired after movement. Accordingly, it is easy to align the first moving plate  411  and the second moving plate  421  with the display unit  10 . 
     The slide mechanism  43  is a slide rail which guides the first moving plate  411  and the second moving plate  421  through the horizontal direction while suppressing the influence of frictional force as much as possible, and is attached to the moving mechanism housing  44 . As shown in  FIGS. 2(   a ) and  2 ( b ), the slide mechanism  43  includes, for example, a ball bearing  43   a  and a rail part  43   b  which extends in the horizontal direction. In this case, a stainless steel ball bearing is used as the ball bearing  43   a , and the rail part  44   b  is formed of stainless steel. Therefore, the slide mechanism, which enables slide resistance to be suppressed even when the temperature changes and vibration is generated, may be configured. Each of the first moving plate  411  and the second moving plate  421  includes a sliding part, which is not shown in the drawing, on back surface side thereof. When the sliding part causes the slide mechanism  43  to slide, the slide mechanism  43  is guided through the horizontal direction. The first moving plate  411  acquires the power of the first driving part  412  through the first transmission mechanism  413 , thereby causing the slide mechanism  43  to slide. In addition, the second moving plate  421  acquires the power of the second driving part  422  through the second transmission mechanism  423 , thereby causing the slide mechanism  43  to slide. 
     Meanwhile, in the embodiment, the slide mechanism  43  is described as a slide rail which is common to the first moving plate  411  and the second moving plate  412 . However, an independent slide rail may be provided for each of the first moving plate  411  and the second moving plate  421 . 
     The moving mechanism housing  44  is a housing which is common to the first moving mechanism  41  and the second moving mechanism  42 , and is formed of, for example, a resin material or non-magnetic metal such as aluminum or the like. 
     Here, the movable range of each of the first moving mechanism  41  and the second moving mechanism  42  of the moving mechanism  40  will be described with reference to  FIGS. 6(   a ) to  6 ( c ). 
     For example, the first moving mechanism  41  causes the first component  31  to move in the horizontal direction in the display region of the display unit  10 . In the embodiment, there are three stop positions (movement end positions) of the first component  31 , that is, the left end part, the central part, and the right end part of the display region. The stop positions are prescribed by the provision positions of three first detection targets  414   b . The movable range of the first moving mechanism  41  is a range in which the first component  31  moves from the left end part to the right end part of the display region, and is shown in  FIG. 6(   a ) based on, for example, the left end of the first component  31 . 
     The second moving mechanism  42  causes the second component  32  to move in the horizontal direction in, for example, the display region of the display unit  10 . In the embodiment, there are three stop positions (movement end positions) of the second component  32 , that is, the left end part, the central part, and the right end part of the display region. The stop positions are prescribed by the provision positions of three second detection targets  424   b . The movable range of the second moving mechanism  42  is a range in which the second component  32  moves from the left end part to the right end part of the display region, and is shown in  FIG. 6(   b ) based on, for example, the right end of the second component  32 . 
     In the display device  100  according to the embodiment, the first transmission mechanism  413  and the second transmission mechanism  423  are configured such that some parts of the movable ranges of both the first moving mechanism  413  and the second moving mechanism  423  overlap (refer to  FIG. 6(   c )) by adjusting the first moving mechanism  413 , the second moving mechanism  423 , the first detecting unit  414 , and the second detecting unit  424 . As above, when configuration is made such that some parts of the movable ranges of the first component  31  and the second component  32  overlap, it is possible to increase the movable ranges thereof, and thus it is possible to change the state of the framing unit  30  to various states like first to third patterns which will be described later. In addition, it is possible to display various display forms by changing the display image of the display unit  10  in accordance with the change of the form of the framing unit. 
     The circuit substrate  50  is a circuit substrate acquired by mounting the control unit  70  which will be described later on the plate-shaped substrate, and is positioned on the back side of the moving mechanism  40 . The circuit substrate  50  is supported inside the case body  60 . 
     The case body  60  is a housing which stores each of the units (the display unit  10 , the pointer type gauge  20 , the framing unit  30 , the moving mechanism  40 , and the circuit substrate  50 ), and includes a storing body  61  and a transparent cover  62 . The storing body  61  is a box-shaped member which includes a front-side opening, and the transparent cover  62  is attached to the opening. 
     Subsequently, the electrical configuration of the display device  100  will be described with reference to  FIG. 7 . 
     The display device  100  includes the control unit  70 , a vehicle information input port  81 , the sensor information input port  82 , the above-described display unit  10 , the needle driving part  21 , the light sources  25 , a first driving part  412  and a second driving part  422 . 
     The control unit  70  includes a microcomputer  71 , a Graphic Display Controller (GDC)  72 , and various driver Integrated Circuits (ICs, not shown in the drawing) which drive the needle driving part  21 , the first driving part  412 , the second driving part  422 , and the back lights of the display unit  10 . For example, the control unit  70  calculates various measured quantities, such as a vehicle speed, the number of revolutions of an engine, the temperature of the engine, the amount of fuel remaining, and the like, controls the operations of the display unit  10  and the pointer type gauge  20 , and displays the calculated measured quantities. 
     The microcomputer  71  includes a Central Processing Unit (CPU), a Read Only Memory (ROM), a Random Access Memory (RAM), and an input and output interface, receives various pieces of information which are input from the vehicle information input port  81  and the sensor information input port  82 , and supplies a control signal to each of the parts. The CPU of the microcomputer  71  reads and executes a predetermined program which is stored in, for example, a ROM in advance in order to perform a display form modifying process which will be described later. 
     The GDC  72  controls the display of the display unit  10  in cooperation with the microcomputer  71 . 
     The vehicle information input port  81  is a port to which vehicle information, such as i) various pieces of state information transmitted from the Electronic Control Unit (ECU) of a vehicle through a communication line, ii) back monitor image information transmitted from the back camera, iii) operation signals indicative of operated content when a user operates operation switches in the vicinity of a handle, various control switches in the vicinity of an instrument panel, an input switch provided in the display device  100 , or the like is input. 
     The sensor information input port  82  is a port to which a detection signal from the first detecting part  414   a  and the second detecting part  424   a  is input. The detection signal includes i) a detection signal acquired when the first detecting part  414   a  detects the first detection target  414   b  (that is, a signal which indicates that the first component  31  of the framing unit  30  is present in a prescribed position), and ii) a detection signal acquired when the second detecting part  424   a  detects the second detection target  424   b  (that is, a signal which indicates that the second component  32  of the framing unit  30  is present in a prescribed position). 
     The display device  100  which includes the above-described configuration uses prescribed information as a trigger, causes the first component  31  of the framing unit  30  (and the pointer type gauge  20 ) and the second component  32  to move in a sliding manner, respectively, modifies the framing unit  30  into a plurality of states, and changes the display of the display unit  10  to correspond to the states under the control of the control unit  70 . 
     The display device  100  controls the driving of the moving mechanism  40  using the control unit  70 , and modifies the framing unit  30  into a “first pattern” state in which the first component  31  and the second component  32  express a ring shape at the center of the display region of the display unit  10 , and a “second pattern” state in which the first component  31  is positioned at the left end part of the display region and the second member  32  is positioned at the right end part of the display region, as shown in  FIG. 5 . Meanwhile, the change in the display of the display unit  10  to correspond to the states will be described later in detail. 
     As described above, the operation of the display device  100  is realized by performing a display form modifying process which is executed by the CPU of the control unit  70 . Hereinafter, the process will be described with reference to  FIG. 8 . 
     (Display Form Modifying Process) 
     The display form modifying process starts on a condition that the control unit  70  receives a prescribed signal which is received through the vehicle information input port  81 . The prescribed signal which functions as a start trigger is, for example, a signal which indicates that a door of a vehicle, in which the display device  100  is built, is open. 
     When the display form modifying process starts, the control unit  70  first performs an initializing operation to cause the first component  31  of the framing unit  30  (and the pointer type gauge  20 ) in the “first pattern” state (refer to  FIG. 5(   a )) to move to the left end and cause the second component  32  to move to the right end (that is, the framing unit  30  is caused to be the “second pattern” state (refer to  FIG. 5(   b ))) (step S 1 ) when a previous display form modifying process ends. 
     More specifically, the control unit  70  controls the driving of the first driving part  412 , and causes the first moving plate  411  to move in the left direction in a sliding manner. Further, if the control unit  70  detects that the first moving plate  411  is positioned at the left end part in cooperation with the first detecting unit  414  (that is, if a detection signal which is supplied from the first detecting part  414   a  is received when the first detecting part  414   a  is positioned in a position facing the first detection target  414   b , which is positioned at the left end part, of three first detection targets  414   b ), the control unit  70  stops the rotation operation of the first driving part  412 , and sets a stop position (detected position) to an original point (reference position) of the first moving plate  411  in a current operation. At the same time, the control unit  70  controls the driving of the second driving part  422 , and causes the second moving plate  421  to move in the right direction in a sliding manner. Further, if the control unit  70  detects that the second moving plate  421  is positioned at the right end part in cooperation with the second detecting unit  424  (that is, if a detection signal which is supplied from the second detecting part  424   a  is received when the second detecting part  424   a  is positioned in a position facing the second detection target  424   b , which is positioned at the right end part, of the three second detection targets  424   b ), the control unit  70  stops the rotation operation of the second driving part  422 , and sets a stop position (detected position) to an original point (reference position) of the second moving plate  421  in a current operation. 
     Then control unit  70  performs such an initializing process in step S 1 . 
     Subsequently, the control unit  70  performs an initial operation to set the framing unit  30  to the “first pattern” state (step S 2 ). 
     More specifically, the control unit  70  controls the driving of the first driving part  412 , and causes the first moving plate  411  to move in the right direction in a sliding manner. Further, if the control unit  70  detects that the first moving plate  411  is positioned at the central part in cooperation with the first detecting unit  414  (that is, if a detection signal which is supplied from the first detecting part  414   a  is received when the first detecting part  414   a  is positioned in a position facing the first detection target  414   b , which is positioned at the central part, of three first detection targets  414   b ), the control unit  70  stops the rotation operation of the first driving part  412 . At the same time, the control unit  70  controls the driving of the second driving part  422 , and causes the second moving plate  421  to move in the left direction in a sliding manner. Further, if the control unit  70  detects that the second moving plate  421  is positioned at the central part in cooperation with the second detecting unit  424  (that is, if a detection signal which is supplied from the second detecting part  424   a  is received when the second detecting part  424   a  is positioned in a position facing the second detection target  424   b , which is positioned at the central part, of the three second detection targets  424   b ), the control unit  70  stops the rotation operation of the second driving part  422 . 
     The control unit  70  performs the initializing operation to set the framing unit  30  to the “first pattern” state as described above. 
     Meanwhile, in the first pattern state, the first component  31  approaches the second component  32  while the first component  31  does not come into contact with the second component  32 . Therefore, as shown in  FIG. 3(   c ), a gap part G is formed between the first component  31  and the second component  32 . The gap part G is provided to prevent the first component  31  from coming into contact with the second component  32  due to the movement precision error of the moving mechanism  40  or due to slight movement generated by a reaction when the moved first moving plate  411  and the second moving plate  421  stop. The display device  100  is configured such that the gap part G is formed by appropriately adjusting the first detecting unit  414 , the second detecting unit  424 , and the like. In addition, in the embodiment, when the display device  100  is viewed from the front side (viewed straight on), the rib r1 which conceals the gap part G using the first component  31  is formed as described above, thereby realizing a ring shape without intermittence (gaps) when the first component  31  approaches the second component  32 . 
     Subsequently, the control unit  70  determines whether or not an ignition is turned on (step S 3 ). When a signal which indicates that the ignition is turned on is received through the vehicle information input port  81 , the control unit  70  determines that the ignition is turned on (step S 3 ; Yes), and the process proceeds to step S 4 . On the other hand, when it is determined that the ignition is not turned on (step S 3 ; No), the process in step S 3  is performed again. In this case, the control unit  70  waits until the signal which indicates that the ignition is turned on is received. 
     In step S 4 , the control unit  70  performs an opening operation. The opening operation is, for example, an operation to display a prescribed opening image on the display unit  10 , to sweep the needle unit  24  of the pointer type gauge  20 , or to turn on or off the light sources  25  or the back lights of the display unit  10 . 
     Subsequently, the control unit  70  determines whether or not a gear is a reverse gear (back gear) (step S 5 ). More specifically, when the control unit  70  receives a signal which indicates that the gear is shifted to the reverse gear through the vehicle information input port  81 , the control unit  70  determines that the gear is the reverse gear (step S 5 ; Yes) and performs a process in step S 8 . When it is determined that the gear is not the reverse gear (step S 5 ; No), the control unit  70  performs a process in step S 6 . 
     In step S 6 , the control unit  70  controls the first driving part  412  and the second driving part  422 , and sets the framing unit  30  to the “first pattern” state. More specifically, a control method which is the same as in step S 2  is used. Meanwhile, when the framing unit  30  is currently in the “first pattern” state already, the control unit  70  maintains the state. 
     Subsequently, the microcomputer  71  of the control unit  70  sets the display of the display unit  10  to the display of a traveling screen in cooperation with the GDC  72  (step S 7 ). The display of the traveling screen is a display, for example, to cause various measured quantities to be displayed on the display unit  10  and the pointer type gauge  20  on the lower side of a traveling screen  91  as shown in  FIG. 8A  depending on vehicle information which is received through the vehicle information input port  81 . More specifically, when the traveling screen display is performed, the display unit  10  displays a tachometer Tm which indicates the number of revolutions of an engine, a fuel meter Fm which indicates the amount of fuel remaining, a battery meter Bm which indicates remaining battery, a mode display Md which indicates a traveling mode, a speed meter index part In (an example of a notification image), and the like in the display region thereof as the traveling screen  91 . As shown in the drawing, the speed meter index part In includes numerical values, graduations, figures, and the like which are displayed inside the ring shape of the framing unit  30  (the “first pattern” state) which is positioned at the central part of the display region. A vehicle speed meter Sm is expressed by the index part In, the pointer type gauge  20 , and the framing unit  30  in the first pattern state. In this case, gauges other than the vehicle speed meter Sm are displayed in digits which are displayed on the display unit  10 . However, the vehicle speed meter Sm is expressed by the analog pointer type gauge  20  (and the framing unit  30 ) and the index part In which is displayed in digits on the display unit  10 . That is, the framing unit  30  functions as the frame of the vehicle speed meter Sm, and the display unit  10  displays the numerical values, the graduations, and the like as the notification image to notify of the vehicle speed along the frame (in accordance with the form of the framing unit  30 ). Meanwhile, when the framing unit  30  is currently in a traveling screen display state already, the control unit  70  maintains the state. 
     When the control unit  70  performs the processes in steps S 6  and S 7 , the process proceeds to step S 10 . 
     In step S 5 , when it is determined that the gear is the reverse gear (step S 5 ; Yes), the control unit  70  controls the first driving part  412  and the second driving part  422 , and sets the framing unit  30  to the “second pattern” state (step S 8 ). More specifically, a control method which is the same as in step S 1  is used. Meanwhile, when the framing unit  30  is currently in the “second pattern” state already, the control unit  70  maintains the state. 
     Subsequently, the microcomputer  71  of the control unit  70  sets the display of the display unit  10  to the display of a back monitor in cooperation with the GDC  72  (step S 9 ). The display of the back monitor, for example, causes the various measured quantities to be displayed on the display unit  10  and the pointer type gauge  20  on the lower side of a back monitor screen  92  as shown in  FIG. 8(   b ) depending on the vehicle information which is received through the vehicle information input port  81 . More specifically, in the display of the back monitor, the display unit  10  displays i) the index part In (an example of the notification image) which includes speed meter numerical values, graduations, figures, and the like in accordance with the half arc shape inside the first component  31  of the framing unit  30  which is positioned at the left end part of the display region in the display region thereof as the back monitor screen  92 , displays ii) warning signs Wa1 and Wa2 (an example of the notification image) in accordance with the half arc shape inside the second component  32  which is positioned at the right end part of the display region, and displays iii) a back monitor Bm (an example of the prescribed image or the notification image) in a rectangular region which appears between the first component  31  and the second component  32  which are open on the right and left sides. 
     The back monitor Bm is built in a vehicle rear part, and projection images of back cameras (not shown in the drawing) which image outside are projected thereon. The warning signs Wa1 and Wa2 include, for example, a warning sign displayed when an obstacle approaches in a case in which a vehicle moves back, a warning sign which provides notification to a driver that the vehicle currently moves back. In addition, the vehicle speed meter Sm is expressed by the index part In, the pointer type gauge  20 , and the first component  31  of the framing unit  30  which is in the second pattern state. In this case, the first component  31  functions as the frame of the vehicle speed meter Sm, and the display unit  10  displays the numerical values, the graduations, and the like as the notification image to notify of the vehicle speed along the frame (in accordance with the form of the first component  31 ). In addition, the second component  32  functions as the frame of the gauge which displays the warning signs Wa1 and Wa2, and the display unit  10  displays the notification image to notify of warning information as the warning signs Wa1 and Wa2 in accordance with the form of the frame. Meanwhile, when the framing unit  30  is currently in the back monitor display state already, the control unit  70  maintains the state. 
     If the control unit  70  performs the processes in steps S 8  and S 9 , the process proceeds to step S 10 . 
     In step S 10 , the control unit  70  determines whether or not the ignition is turned off. When a signal which indicates that the ignition is turned off is received through the vehicle information input port  81 , the control unit  70  determines that the ignition is turned off (step S 10 ; Yes), and the process proceeds to step S 11 . On the other hand, when it is determined that the ignition is not turned off (step S 10 ; No), the process returns to step S 5 . 
     In step S 11 , the control unit  70  performs an end operation to set the framing unit  30  to the “first pattern” state. More specifically, a control method is the same as in step S 2 . Meanwhile, when the framing unit  30  is currently in the “first pattern” state already, the control unit  70  maintains the state. 
     When the process in step S 11  is performed, the control unit  70  ends the display form modifying process. 
     In the above-described display form modifying process, the display device  100  displays various pieces of information in two display states (the traveling screen display and the back monitor display) by changing the framing unit  30  into the first and second pattern states and by displaying images, which differ depending on before and after the change in the patterns, on the display unit  10 . However, the display states of the display device  100  are not limited thereto. For example, the display device  100  can cause the display unit  10  to display radio display as shown in  FIG. 10(   b ) while causing the first member  31  and the second member  32  to move to the left end part in the display region of the display unit  10  and setting the display state to a “third pattern” state (refer to  FIG. 10(   a )) in which the ring shape is expressed using both the members. 
     With regard to the radio display, for example, the display unit  10  displays the speed meter index part In (an example of the notification image) and a warning sign Wa3 (an example of the notification image), which indicates whether or not a side break is applied, as the radio display screen  93  in accordance with the ring shape of the framing unit  30  which is positioned on the left side of the display region, and displays a radio display image Rd in the right-side region of the display region which is empty due to the movement of the framing unit  30 . The traveling screen display ( FIG. 8(   a )), the back monitor display ( FIG. 8(   b )), or the like is switched to the radio display on a condition that the control unit  70  receives a signal, which indicates operation content transmitted when a user selects radio using various control switches in the vicinity of an instrument panel. 
     In addition, the display device  100  may display a car navigation image (an example of a second notification image) in the region, which corresponds to a space formed when the first component  31  and the second component  32  are open on the right and left sides, of the display region of the display unit  10  in the second pattern state (refer to  FIG. 5(   b )). 
     In addition, when the display device  100  expresses the ring shape at the left end part of the display region (third pattern state (refer to  FIG. 10(   a ))) by moving the framing unit  30 , the display device  100  may display information related to a vehicle right side (for example, information about the right side components of the vehicle, such as an image of the right side of the outside of the vehicle, an indicator which notify of the open state of a right door, abnormality of right tire pressure, or the like) in the right-side region of the display region which is empty because the framing unit  30  is moved. If so, since the information is displayed so as to link with a sense of direction of the user (mostly, a driver), the user can intuitively and easily grasp the displayed information. In the same manner, when the display device  100  expresses the ring shape at the right end part of the display region, by moving the framing unit  30 , the display device  100  may display information related to a vehicle left side in the left-side region of the display region which is empty because the framing unit  30  is moved. 
     In addition, the display device  100  may cause the framing unit  30  to move from one end of the display region to the other end while maintaining the ring shape. Therefore, it is possible to effectively cause the user to observe the display device  100  or to perform a new operation. 
     The display device  100  according to the embodiment includes the display unit  10  (an example of the display part) that displays a display image including a notification image to notify of the state of the vehicle in the display region, the framing unit  30  (an example of the frame body) that is positioned on the display region of the display unit  10  and includes the first component  31  and the second component  32 , and the moving mechanism  40  (an example of the movement unit) that causes at least one of the first component  31  and the second component  32  to move. Segmentation is performed on the framing unit  30  in such a way that at least one side of the first component  31  and the second component  32  is moved by the movement unit. Before the segmentation is performed, the framing unit  30  surrounds one of the display regions of the display unit  10 . The display unit  10  displays the display image which differs depending on before and after the segmentation is performed on the framing unit  30 , and displays the notification image in accordance with the form of the framing unit  30  at least one of before and after the segmentation is performed on the framing unit  30 . According to the display device  100 , since it is possible to change the display image in accordance with the movement position of the framing unit  30 , it is possible to realize a new display. 
     In addition, segmentation is performed on the framing unit  30  in the horizontal direction based on a fact that the movement direction of the first component  31  and the second component  32  is the horizontal direction when viewed from an observer of the display device  100 . Therefore, it is possible to cause the framing unit  30  to move in a wide range in the display region of the display unit for a vehicle in which the horizontal direction is a long direction in many cases, and it is possible to display various state images using the regions which are formed in accordance with the movement of the framing unit  30  while realizing a new display. 
     In addition, before segmentation is performed on the framing unit  30 , the first component  31  and the second component  32  of the framing unit  30  approach each other while the first component  31  does not come into contact with the second component  32 , the gap part G is formed between the first component  31  and the second component  32  which approach each other, and the rib r1 which conceals the gap part G is formed on the first component  31 . Therefore, when the display device  100  is viewed straight on and a first form (ring shape) is expressed by the first component  31  and the second component  32 , it is possible to express the smooth first form without the generation of unintended intermittence (gaps). Since both the components do not come into contact with each other, it is possible to suppress shock from being generated during movement, thereby leading to prevention of failure. In addition, impulsive sounds are not generated when both the components collide with each other, thereby leading to prevention of noise. 
     The display device  100  according to the embodiment includes the display unit  10  (an example of the display part) that displays a display image including a notification image to notify of the state of a vehicle in the display region, the first component  31  and the second component  32  that are positioned on the display region of the display unit  10 , the first transmission mechanism  413  (an example of the first mechanism) that causes the first component  31  (an example of a first movable member) to move in a first movable range in the first direction (horizontal direction), and the second transmission mechanism  423  (an example of the second mechanism) that causes the second component  32  (an example of a second movable member) to move in a second movable range, at least a part of which overlaps with the first movable range, along the first direction. After at least one side of the first component  31  and the second component  32  moves, the display unit  10  displays the display image which is different from that acquired before the movement occurs. According to the display device  100 , it is possible to increase the movement ranges of the first component  31  and the second component  32  and it is possible to display different display images in accordance with the movement of both the components, and thus it is possible to perform the display in various display states. 
     In addition, the first transmission mechanism  413  and the second transmission mechanism  423  are positioned in the direction (vertical direction) which is perpendicular to the movement direction (horizontal direction) of the first component  31  and the second component  32 , at a predetermined interval from each other. Therefore, it is possible to provide the display device  100  with suppressed thickness in the front and back directions. 
     Meanwhile, the invention is not limited to the above-described embodiment, a modification example below, and the drawings. It is apparent that addition of appropriate changes (including removal of components) is possible. 
     Modification Example 
     In the above embodiment, the example in which the first transmission mechanism  413  and the second transmission mechanism  423  are arranged in the horizontal direction without deviation is shown. However, the invention is not limited thereto. As shown in  FIG. 11 , both transmission mechanisms may be arranged to deviate in the horizontal direction. If the display device  100  is configured such that at least some parts of the movable range of the first moving mechanism  41  which includes the first transmission mechanism  413  overlap with the movable range of the second moving mechanism  42  which includes the second transmission mechanism  423  even when both the transmission mechanisms deviate from each other, it is possible to increase the movable ranges, and thus it is possible to perform the display in various display states. 
     In addition, in the above embodiment, since the display device  100  is configured to be thin in the front and back directions, the example in which the first transmission mechanism  413  and the second transmission mechanism  423  are respectively arranged at a predetermined interval in the vertical direction is shown. However, the invention is not limited thereto. When there is a request for design, it is possible to configure the display device by arranging each of the mechanisms at a predetermined interval in the front and back direction. 
     In addition, in the above embodiment, the example in which the framing unit  30  is moved in the horizontal direction by the moving mechanism  40  is shown. The reason for this is that, since the long direction of the display device  100  according to the embodiment is the horizontal direction, it is possible to increase the movable ranges in the display region of the display device  100  when the framing unit  30  is moved in the horizontal direction. However, the movement direction is not limited thereto and the movement direction may be the vertical direction, the oblique direction, or the like. It is possible to appropriately modify the movement direction by taking the form of the display device into consideration. 
     In addition, in the above embodiment, the example in which the framing unit  30  moves in the display region of the display unit  10  is shown. However, the invention is not limited thereto. A newer display state may be possible in such a way that a part of the framing unit  30  moves to protrude from the display unit  10  or the entire framing unit  30  moves up to the outside of the display unit  10 . 
     In addition, in the above embodiment, three movement completion positions of the first moving plate  411  (first component  31 ) are prescribed by arranging three first detection targets  414   b , and three movement completion positions of the second moving plate  421  (second component  32 ) are prescribed by arranging three second detection targets  424   b . However, the invention is not limited thereto. The movement completion positions may be prescribed by arranging two or four or more first detection targets  414   b  and second detection targets  424   b.    
     In the above embodiment, the example in which the display device  100  includes the substantial pointer type gauge  20  is shown. However, the invention is not limited thereto. The display device may display needles in the display unit  10  or display numerical values (measured values) without including substantial needles. 
     In addition, in the above embodiment, the example in which a circular shape (ring shape) is made when the first component  31  of the framing unit  30  approaches the second component  32  is shown. However, the invention is not limited thereto. A part of the display region may be surrounded in such a way that an elliptical shape, a rectangular shape, or a polygon is made when the first component approaches the second component, and a part of the display region may be surrounded with a form in which some parts of sides are chipped when the first component approaches the second component. 
     In addition, in the above embodiment, the example in which the framing unit  30  is segmented into two components (first component  31  and second component  32 ) due to movement is shown. However, the invention is not limited thereto. Three or more components may be acquired through segmentation. 
     In addition, in the above embodiment, the example in which, when the first component  31  approaches the second component  32  and when the display device  100  is viewed from the front side (viewed straight on), two ribs which cover the gap part G are two ribs r1 which are provided together in the first framing cover  312  is shown. However, the invention is not limited thereto. The two ribs which cover the gap part G may be provided together in the second framing cover  322 , or one of the two ribs which cover the gap part G as described above may be provided in the first framing cover  312  and the other one may be provided in the second framing cover  322 . 
     In addition, in the above embodiment, the example in which the second magnet body  23  is rotated by the magnetic force of the first magnet body  22  attached to the needle driving part  21  is shown. However, the invention is not limited thereto. 
     Configuration may be made such that the second magnet body  23  is wound up by a pair of coils, and the second magnet body  23  is rotated by applying electricity to the pair of coils (that is, the needle unit  24  is rotated). The pair of coils is connected to the control unit  70  through the conduction member, similarly to, for example, the light sources  25 . In this case, the needle driving part  21 , the first magnet body  22 , and the substrate B (refer to  FIGS. 2(   b ) and  3 ( b )) are not necessary. 
     In the above embodiment, the example in which the display device is a vehicle gauge which is built in a vehicle is shown. However, the invention is not limited thereto. The display device may be a gauge which is built in a watercraft, farm machinery, an aircraft, a ship, an electric train, or the like.
