  Since the dimensions of the movable panel are substantially the same as the height dimension and the width dimension of the apparatus body, the front surface of the movable panel when the movable panel is in the closed posture is displayed on the display unit or the operation unit. It can be widely used as a part.

  However, in the open position, the movable panel having the dimensions rotates so as to fall forward as it is, so that in the open position, the projecting dimension of the movable panel from the front part of the device main body becomes large. . In the case of an on-vehicle electronic device, a shift lever or the like is usually arranged in front of the electronic device. Therefore, if the movable panel is opened as it is as described above, the movable panel may hit the shift lever depending on the vehicle type. Or it may interfere with the operation of the shift lever. Further, when the movable panel is set to the open posture, there may be a case where an adverse effect occurs in using various facilities located under the in-vehicle electronic device.

  In particular, the movable panel can be operated in the open position when the operation surface of the movable panel can be operated, or the display unit provided on the movable panel can be viewed in the open position. Since the vehicle is often driven as it is, the above-described adverse effects are more likely to occur.

  The present invention solves the above-mentioned conventional problems, and when the projecting end of the movable panel is in an open posture projecting forward of the device body, the projecting amount of the movable panel from the front of the device body can be shortened. An object of the present invention is to provide an electronic device having the movable panel.

According to a first aspect of the present invention, there is provided an electronic apparatus having a device main body and a movable panel provided at a front portion of the device main body.
Said movable panel has a front portion and a base and two opposed faces, a dimension between the front Kisaki portion said base variably,
The device main body includes the movable panel, a closed posture in which any one of the surfaces faces the front of the device main body, and a protruding end that is one of the front portion and the base portion is a front portion of the device main body. Attitude control means for setting the protruding attitude away from the front,
Protrusion amount control means for shortening the dimension between the front portion and the base portion of the movable panel in the protruding posture rather than the closed posture is provided.

According to a second aspect of the present invention, there is provided an electronic apparatus having a device main body and a movable panel provided at a front portion of the device main body.
The movable panel has a front portion, a base portion, and two opposing surfaces, and has a pivot point on either the front portion side or the base portion side so that the posture of the movable panel can be changed. And
The device main body includes the movable panel, a closed posture in which any one of the surfaces faces the front of the device main body, and a protruding end that is one of the front portion and the base portion is a front portion of the device main body. Attitude control means for setting the protruding attitude away from the front,
Protrusion amount control means is provided for reducing the dimensions of the pivot fulcrum of the movable panel and the projecting end in the projecting posture rather than the closed posture.

  In both the above inventions, when the movable panel is in a projecting posture in which the projecting end projects forward, the dimension of the movable panel is shortened, or the distance between the projecting end and the rotation fulcrum is shortened. Therefore, the projecting dimension from the front part of the device main body can be shortened when the movable panel is in the projecting posture. Further, when the movable panel is in the closed posture, the area of the surface of the movable panel can be made equal to the area of the front portion of the device body.

  Therefore, for example, when it is configured to be in a closed position so that the rear surface of the movable panel without the display unit or operation unit is directed forward, the display unit or operation unit does not appear at the front of the device body, The electronic device can be prevented from being stolen when the electronic device is mounted on a vehicle.

  Alternatively, when the display unit or the operation unit is arranged on the surface of the movable panel that faces the front of the device body when the movable panel is in the closed posture, the arrangement area of the display unit or the operation unit is changed to the front part of the device body. The display area can be enlarged or a large number of operation members can be arranged.

  For example, the device main body is provided with a reciprocating member that reciprocates toward the front and the rear of the device, and a drive unit that reciprocates the reciprocating member, and the posture control unit includes the reciprocating member of the reciprocating member. Along with the movement, the movable panel is changed between the closed posture and the protruding posture.

The posture control means of the present invention may be set to the closed posture and the protruding posture by rotating the movable panel using gears, as described in Patent Document 1 , for example. .

  According to the present invention, the movable panel is supported so that the position of the protruding end can be changed with respect to the reciprocating member, and the protruding amount control means is interlocked with the operation of the attitude control means. In addition, a variable member that changes the dimensions may be provided.

  In this case, the variable member reciprocates together with the reciprocating member, and the position of the protruding end is changed by changing the posture of the variable member depending on whether the reciprocating member moves backward or forward. It can be configured that cam means for changing is provided.

  Further, according to the present invention, as described in the following embodiment, a second movable panel is supported on the reciprocating member, and the second movable panel is moved when the reciprocating member is retracted. A panel is housed in the device main body, and the second movable panel moves forward of the device main body as the reciprocating member moves forward, and the second control panel is moved together with the movable panel by the posture control means. The posture of the movable panel may be changed.

  However, the present invention is not limited to the one having the second movable panel as in the following embodiments, and it is needless to say that only one movable panel may be provided.

  In the present invention, when the movable panel is in the closed posture, the surface of the movable panel can be set to the same area as the front surface of the device main body, and when the movable panel is in the protruding posture, The projecting dimension from the front can be shortened. For this reason, the movable panel protruding in front of the apparatus main body is less likely to be an adverse effect on the operation of other equipment.

The control groove 63 is folded back from the first control unit 63a on the side close to the rotation fulcrum shaft 8 and the first control unit 63a toward the front part 11 side of the second movable panel 10. And a second control unit 63b that extends.

Next, a series of operations of the on-vehicle electronic device 1 will be described.
(Not in use)
When the on-vehicle electronic device 1 is not used, as shown in FIGS. 3A and 7A, the reciprocating member 7 is at the first retracted position (i) that is most retracted in the X1 direction.

  At this time, the restriction shaft 43 provided at the base end portion 41 a of the restriction member 41 is located at the rear end portion 44 b of the control groove 44 formed in the reciprocating member 7, and the restriction shaft 43 is attached to the support base 50. The switching groove 51 thus formed is located rearward (X1 direction) in the retreating groove 51a. The restricting member 41 extends in parallel in the reciprocating direction of the reciprocating member 7, and the second movable panel 10 has a horizontal posture rotated clockwise with the rotation support shaft 8 as a fulcrum. Are accommodated in the device main body 2.

  In the non-use state, as shown in FIG. 7A, the stopper lever 52 rotatably supported by the support base 50 is stabilized by the torsion spring 56 while being rotated counterclockwise. It has been.

  As shown in FIG. 1, in a non-use state, the second movable panel 10 in a parallel posture is housed inside the device main body 2, and the open / close movable panel 20 is in a vertical posture and positioned at the front portion of the device main body 2. Closed posture. At this time, as shown in FIG. 6 (A), the protruding cam portion 83 of the variable member 80 rides on the bottom surface 3 b of the housing 3, and the open / close movable panel 20 is formed between the front portion 21 and the base portion 22. The dimensions are enlarged, and the distance between the tip portion 21 and the rotation fulcrum shaft 8 is also enlarged. Further, as shown in FIG. 1, the upper piece 20A and the lower piece 20B have the back surface 24 substantially in the same plane and directed forward.

(Operation to switch from non-use state to use state)
When in the non-use state, the operation to switch to the use state is performed using the remote controller, or the operation button provided inconspicuously on the back surface 24 of the open / close movable panel 20 (the back surface of the upper piece 20A) is driven. The drive motor of the means 30 is started, the pinion gear 32 rotates, a forward force acts on the rack member 31, and the reciprocating member 7 moves in the X2 direction.

  As shown in FIG. 6B, immediately after the reciprocating member 7 moves forward, the protruding cam portion 83 of the variable member 80 moves forward from the bottom surface 3 b of the housing 3, and the upper piece is moved by the biasing force of the tension spring 72. 20A is pulled down to the base 22 side, and the lower end portion 24a on the back surface of the upper piece 20A overlaps the wall portion 24c on the back surface of the lower piece 20B. At this time, the dimensions of the tip 21 and the base 22 of the movable movable panel 20 are reduced, and the distance between the pivot point 8 and the tip 21 is also shortened.

  FIG. 3B and FIG. 7B show a state in which the reciprocating member 7 has moved forward (X2 direction) to the forward position (iii). When the reciprocating member 7 moves from the first retracted position (i) to the advanced position (iii), the restricting shaft 43 provided at the base end portion 41 a of the restricting member 41 has a rear end portion 44 b of the control groove 44. While moving to the reciprocating member 7, it moves forward along the retreating groove 51 a of the switching groove 51 formed in the support base 50.

  While the reciprocating member 7 moves from the first retracted position (i) shown in FIGS. 3A and 7A to the advanced position (iii) shown in FIG. Stay in a horizontal position. Therefore, the relative angle between the second movable panel 10 and the open / close movable panel 20 does not change, the open / close movable panel 20 moves forward in the vertical posture toward the front of the device body 2, and the second movable panel 10 is horizontal. Move forward in the posture and exit to the front of the device body 2.

  Further, while the reciprocating member 7 moves from the first retreat position (i) to the advance position (iii), the restriction shaft 43 that advances in the retreat groove 51a hits the lower side 52e in front of the stopper lever 52, The stopper lever 52 is once turned clockwise. When the restricting shaft 43 reaches the front end of the retreating groove 51a, the stopper lever 52 is returned counterclockwise by the urging force of the torsion spring 56. Therefore, as shown in FIGS. 3B and 7B, when the reciprocating member 7 moves from the first retracted position (i) to the advanced position (iii), the retracting groove 51a of the switching groove 51 is provided. The front end of the stopper lever 52 is kept closed by the stopper portion 52c.

  In the switching operation to the use state, when the reciprocating member 7 reaches the forward position (iii) shown in FIGS. 3 (B) and 7 (B), the drive motor immediately reverses and the pinion gear 32 is rotated. Is driven counterclockwise, and the reciprocating member 7 is moved rearward (X1). When the reciprocating member 7 moves to the second retracted position (ii) shown in FIGS. 5 and 8, the drive motor stops. In this embodiment, the stop position of the reciprocating member 7 at the second retracted position (ii) is slightly closer to the front (X2 direction) than the first retracted position (i). However, the stop position of the reciprocating member 7 may be the same in the second retracted position (ii) and the first retracted position (i), and the second retracted position (ii) is the first retracted position (ii). The rearward position (i) may be rearward.

  When the reciprocating member 7 moves backward from the forward movement position (iii) shown in FIG. 3B, the regulating shaft 43 comes into contact with the stopper portion 52c of the stopper lever 52 and moves backward as shown in FIG. It is regulated so as not to enter the groove 51a. Therefore, when the reciprocating member 7 moves backward, the rotation fulcrum shaft 8 moves backward together with the reciprocating member 7 in a state where the retraction of the restriction shaft 43 is restricted by the stopper portion 52 c. Therefore, as shown in FIGS. 4A, 4B, and 5 continuously, as the reciprocating member 7 moves backward, the regulating member 41 rotates clockwise with the regulating shaft 43 as a fulcrum. At the same time, the second movable panel 10 rises so as to rotate counterclockwise about the rotation fulcrum shaft 8 as a fulcrum.

  When the reciprocating member 7 moves from the forward position (iii) to the second retracted position (ii), the control groove 44 formed in the reciprocating member 7 slides with the restriction shaft 43. Since the front end portion 44a of 44 is directed upward (in the Z1 direction), when the reciprocating member 7 moves backward, the regulating shaft 43 slides in the control groove 44 to support the support base 50. It rises along the connecting groove 51c of the switching groove 51 formed in the above. When the restricting shaft 43 moves up in the connecting groove 44, the restricting shaft 43 lifts the jumping portion 52b of the stopper lever 52, and the restricting shaft 43 reaches the front end of the restricting groove 51b. Therefore, after that, while the reciprocating member 7 is retracted from the position shown in FIG. 4B to the position shown in FIG. 5, the restriction shaft 43 enters the restriction groove 51b.

  While the restriction shaft 43 moves backward in the restriction groove 51b by a short distance, the second movable panel 10 further rotates counterclockwise as shown in FIG. 4B to FIG. As a result, the second movable panel 10 is retracted while the back surface 14 is in a vertically oriented posture, and the back surface 14 contacts the peripheral wall 4b of the nose 4 as shown in FIG.

  Further, when the restriction shaft 43 pushes up the flip-up portion 52b and the stopper lever 51 rotates in the clockwise direction, the biasing direction by the torsion spring 56 is reversed, and the stopper lever 51 is rotated in the clockwise direction. It stabilizes at.

  Since the second movable panel 10 and the support member 70 that supports the openable / closable movable panel 20 are coupled by the coupling member 60, the second movable panel in the process shown in FIGS. As 10 rotates and changes its posture, the movable movable panel 20 also rotates together with the support member 70 to change its posture.

  The opening angle between the second movable panel 10 and the movable movable panel 20 and the support member 70 is controlled by the connection member 60 moving on the side surface of the second movable panel 10. Further, the movement of the connecting member 60 is controlled in accordance with a change in the relative angle between the second movable panel 10 and the regulating member 41.

  Along the guide grooves 17 and 17 formed on the side surface of the second movable panel 10, the connecting member 60 is movable in a direction parallel to the back surface 14 of the second movable panel 10. In the state of FIG. 3A and FIG. 3B, since the second movable panel 10 and the restricting member 41 are both in a horizontal posture, they are connected by an urging groove 47 formed at the front portion of the restricting member 41. The urging pin 62 provided on the member 60 is moved toward the front portion 11 of the movable panel 10, and as a result, the connecting member 60 is moved to the front portion 11 side on the side surface of the second movable panel 10. Yes. At this time, the control pin 28 provided on the support member 70 that supports the movable movable panel 20 is positioned at the terminal end of the first control unit 63 a in the control groove 63 formed in the connecting member 60. Therefore, in FIGS. 3A and 3B, the opening angle between the back surface 14 of the second movable panel 10 and the back surface 24 of the open / close movable panel 20 is approximately 90 degrees.

  From FIG. 3 (B) to FIG. 4 (A), the restricting member 41 rotates clockwise with the restricting shaft 43 as a fulcrum, and the second movable panel 10 rotates counterclockwise with the turning fulcrum shaft 8 as a fulcrum. When moved, the biasing pin 62 is biased toward the base 12 of the second movable panel 10 by the biasing groove 47, and the connecting member 60 moves toward the base 12 on the side surface of the second movable panel 10. At this time, the control pin 28 provided on the support member 70 is guided to an intermediate portion between the first control portion 63 a and the second control portion 63 b of the control groove 63 formed in the connecting member 60. The first control unit 63 a has a pattern shape that gradually moves away from the back surface 14 toward the front part 11 of the second movable panel 10. Therefore, the opening angle of the back surface 14 and the back surface 24 of the second movable panel 10 and the openable / closable movable panel 20 is enlarged by the guiding operation. In the state of FIG. Is larger than 90 degrees. The opening angle θ is widest in the case of FIG.

  Further, when moving from FIG. 4A through FIG. 4B to FIG. 5, the connecting member 60 is further moved toward the base 12 of the second movable panel 10 by the biasing groove 47. . At this time, the control pin 28 provided on the support member 70 is guided in the second control portion 63 b of the control groove 63. The second control unit 63 b has a pattern shape that gradually approaches the back surface 14 toward the tip 11 of the second movable panel 10. Therefore, the opening angle between the back surface 14 of the second movable panel 10 and the back surface 24 of the open / close movable panel 20 is shown in FIG. 4A from the state of FIG. 4A to the state of FIG. A little smaller than θ. In the use state shown in FIG. 5, the second movable panel 10 is in a substantially vertical posture, and the open / close movable panel 20 is in an oblique posture in which the tip portion 21 that is a protruding end is slightly downward.

  The change in the opening angle between the second movable panel 10 and the open / close movable panel 20 in the process from FIG. 3A to FIG. 5 and the opening angle in the use state shown in FIG. Further, it can be changed freely by setting the pattern shape of the control groove 63.

  The reciprocating member 7 is continuously retracted from the advance position (iii) shown in FIGS. 3B and 7B toward the second retract position (ii) shown in FIGS. 5 and 8. However, the reciprocating member 7 may be stopped by stopping the drive motor in the middle of the reciprocating member 7 from the advance position (iii) to the second retracted position (ii). Thus, by stopping the reciprocating member 7, the postures of the second movable panel 10 and the open / close movable panel 20 can be set to an angle other than the angular posture shown in FIG.

  For example, when the drive motor is stopped when the reciprocating member 7 reaches the position shown in FIG. 4A, the disk insertion opening 4c formed in the nose 4 is located above the second movable panel 10 and the open / close movable panel 20. You can set the mode that appears in.

Further, the disk D that has been driven by the disk drive device in the housing 3 can be extracted through the space above the second movable panel 10 and the open / close movable panel 20.

  In the on-vehicle electronic device 1, in the state shown in FIG. 4A, the opening angle θ between the second movable panel 10 and the openable / closable movable panel 20 is larger than that in FIG. Is the maximum opening angle θ. Further, since the opening side of the angle θ is directed upward, a wide space for allowing the disk D to pass therethrough can be secured above the second movable panel 10 and the open / close movable panel 20, and the disk D is in a horizontal posture. It becomes easy to insert toward the disc insertion opening 4c.

  Further, when the drive motor is stopped when the reciprocating member 7 reaches FIG. 4B, the use surface 13 of the second movable panel 10 is in an inclined posture in which it is inclined upward, and the movable movable panel 20 is in a horizontal posture. Thus, it is possible to set a mode in which the use surface 23 is substantially upward.
