[0001]
BACKGROUND OF THE INVENTION
The present invention includes an electronic device in which a movable member having a display member and / or an operation member housed in a case protrudes outward from the case, or a moving member such as an optical head or a magnetic head that moves in the case. The present invention relates to an electronic device, an electronic device having a moving member such as a recording medium driving member that moves in a case along a direction in which the recording media are arranged in order to select and drive a plurality of recording media.
[0002]
[Prior art]
In an in-vehicle electronic device, a moving member provided with a display member such as a liquid crystal display device or a moving member provided with an operation member moves from the state accommodated in the case so as to protrude outward from the case. In some cases, the moving member provided with the display member rotates outside the case, and the screen rotates in an easy-to-see direction for passengers in the passenger compartment.
In an electronic apparatus that performs a recording or reproducing operation on a recording medium such as a magnetic disk or an optical disk, a moving member such as a magnetic head or an optical head moves in the case.
[0003]
Further, in an electronic apparatus in which any one of a plurality of recording media called a disk changer is selected and recording or reproduction is performed on the recording medium, a moving member including a disk rotation driving unit and a head is provided on the recording medium. The recording medium moves along the alignment direction, and any recording medium is selected and driven by the mechanism in the moving unit.
[0004]
As described above, in an electronic device including a moving member that moves inside or outside the case or inside the case, an electronic circuit provided in the case and the moving member are connected by a soft wiring material. Electric power is supplied to the moving member via the wiring member, or a signal is transmitted between the moving member and the electronic circuit.
[0005]
[Problems to be solved by the invention]
In the electronic device having the moving member, when the connecting portion between the wiring member and the moving member is a moving side connecting portion, and the connecting end of the wiring member on the opposite side is the base end side connecting portion, the moving member is Since the length of the wiring member is determined in a state farthest from the proximal end side connection portion, the wiring member is bent when the moving member moves toward the proximal end side connection portion.
[0006]
If the bending of the wiring member is left in a free state, the wiring member may be rubbed against the moving moving member or may be bent between the moving member and the wall surface, leading to disconnection of the wiring member. Alternatively, the bent portion of the wiring member may swell and hit another electronic component or movable mechanism component adjacent to the moving region of the moving member, resulting in damage to the wiring member.
[0007]
In order to prevent the wiring material from bulging, it is conceivable to provide a wiring guide fixed in the case, but this wiring guide must be arranged at a position outside the moving area of the moving member, It is difficult to reliably guide the wiring material that extends or bends due to the movement of the member. If the wiring guide is disposed at a position outside the moving region of the moving member, the wiring material is forcibly bent at a position outside the moving region of the moving member, and excessive bending stress acts on the wiring material. It is easy to break and damage the wiring.
[0008]
The present invention solves the above-mentioned conventional problems, can reliably guide a wiring material that extends or bends as the moving member moves, and does not cause excessive bending stress to act on the wiring material. It is another object of the present invention to provide an electronic device having a moving member that enables the above.
[0009]
[Means for Solving the Problems]
The present invention includes a reciprocating member provided in a case so as to be reciprocally movable, and a moving member rotatably supported at a tip portion of the reciprocating member, and when the reciprocating member advances. The moving member moves to the outside of the case in a horizontal posture, and further, the moving member can be rotated to a rising posture outside the case, and is provided in the case with an electronic device or an electronic component built in the moving member. In an electronic device provided with a soft wiring material that transmits power and / or signals to and from an electrical circuit,
The reciprocating member is provided with a wiring guide member and a wiring restricting member formed of a shaft having a smooth surface or a rotatable roller extending in a direction orthogonal to the moving direction, and spaced apart in the moving direction. the guide member is located inside the bending portion of the wiring member, the wiring regulating member is located outside of the flexure of the wiring member,
When the reciprocating member reciprocates, the bent portion is moved by the movement of the wiring guide member , and when the wiring restricting member moves and when the moving member rotates, the bent portion swells. Is suppressed.
[0010]
In the present invention, the wiring guide member follows the moving member and moves together with the moving member. When the moving member moves toward the base end side connecting portion, which is a connecting portion on the electronic circuit side, the amount of bending of the wiring material increases, but due to the movement of the wiring guide member, the bending portion of the wiring material is moved to the moving member. It is moved in advance of the moving direction. Therefore, the bent portion of the wiring member is not sandwiched between the moving member and the adjacent member such as the wall surface.
[0014]
In this invention, when the moving member moves to the connection side end, the wiring guide bending portion is pulled backward by the wiring guide member, and the bending portion is sandwiched between the moving member and the wall surface. Furthermore, the bulge of the bending of the wiring material moved by the wiring guide member is suppressed by the wiring regulating member.
[0015]
In the present invention, when the connecting portion between the moving member and the wiring member is a moving side connecting portion, and the connecting end portion of the wiring member opposite to the moving member is a base end side connecting portion, the moving member is When moving in a direction away from the base end side connecting portion, the wiring guide member is positioned between the moving side connecting portion and the base end side connecting portion, and the moving member is the base end side connecting portion. When moving toward or beyond the base end side connection portion, the wiring guide member is effective when moving to the rear of the base end side connection portion.
[0016]
When the moving member moves toward the connection side end, the wiring material accumulates in the base end side connection portion to form a bend at that position, but the wiring guide member moves rearward from the base end side connection portion. Thereby, the bending part which generate | occur | produces the base end side connection part vicinity is pulled back rather than the base end side connection part by the wiring guide member. Therefore, excessive bulging of the bent portion does not occur in the vicinity of the proximal end side connection portion.
[0017]

A material may be provided.
[0028]
As shown also in FIG. 1, the reciprocating drive member 10 is provided with a wiring guide member 16 and a wiring regulating member 17. The wiring guide member 16 and the wiring regulating member 17 are shafts or rods having a smooth surface, and are fixed to the reciprocating drive member 10 by means such as screwing or caulking.
[0029]
Alternatively, the wiring guide member 16 and the wiring restricting member 17 may be rollers provided so as to be rotatable around the shaft.
[0030]
In the embodiment shown in FIGS. 1 to 3, a wiring restriction member 17 is disposed between the moving member 7 and the wiring guide member 16. The wiring member 13 extending rearward from the rear surface of the lower end of the moving member 7 passes below the wiring restricting member 17, passes over the wiring guide member 16, and extends to the proximal end side connecting portion 15.
[0031]
A bottom wall surface 2a of the housing 2 is present below a line connecting the moving side connecting portion 14 and the base end side connecting portion 15. Therefore, the wiring member 13 is on the side opposite to the bottom wall surface 2a, that is, the installation region 5 side is the bending side (bulging side). The wiring guide member 16 and the wiring regulating member 17 are provided on the upper side (installation region 5 side), that is, on the bulging side of the wiring member 13, from the line connecting the moving side connection portion 14 and the proximal end side connection portion 15. Yes. The wiring guide member 16 is provided inside the bent portion 13a of the wiring member 13, and the wiring regulating member 17 is arranged outside the bent portion 13a.
[0032]
The wiring guide member 16 and the wiring restricting member 17 extend in a direction orthogonal to the moving direction (Y1-Y2 direction) of the moving member 7. 1, 2 and 3, the wiring guide member 16 and the wiring regulating member 17 are arranged at the same height from the bottom wall surface 2a. However, the wiring guide member 16 is at a higher position with respect to the line (or the bottom wall surface 2 a) connecting the moving side connection portion 14 and the base end side connection portion 15, and the wiring restriction member 17 is more than the wiring guide member 16. May be in a lower position.
[0033]
As shown in FIGS. 2 and 3, the wiring guide member 16 and the wiring regulating member 17 move together with the moving member 7 along the moving direction of the moving member 7. At this time, the wiring guiding member 16 and the wiring regulating member 17 are moved. The functions of are as follows.
First, the wiring guide member 16 exhibits a function of moving the bending portion 13a. The wiring guide member 16 is located inside the bent portion 13 a of the wiring member 13 and moves together with the moving member 7. In FIG. 3A, the moving side connecting portion 14 and the proximal end side connecting portion 15 are farthest apart. At this time, the wiring guide member 16 moves forward together with the moving member 7 and is positioned between the moving side connection portion 14 and the proximal end side connection portion 15. Further, the wiring member 13 extends most and the bulge of the bent portion 13a is the smallest.
[0034]
FIG. 2 (A) or FIG. 3 (B) shows that the moving member 7 has moved most backward from the position. At this time, the moving side connection portion 14 and the proximal end side connection portion 15 are closest to each other, and the bending of the wiring member 13 between both the connection portions 14 and 15 is increased. However, since the wiring guide member 16 moves backward, the bent portion 13a is moved backward by the wiring guide member 16. Therefore, as shown in FIG. 3B, even if the moving member 7 moves backward in the same area 4 as the wiring area of the wiring member 13, the wiring guide member 16 moves the bent portion 13a backward. Therefore, in the state of FIG. 3 (B), a phenomenon such as the bending portion 13a being sandwiched between the moving member 7 and the bottom wall surface 2a of the housing 2 and being forcibly folded does not occur, and the wiring member 13 can be protected. .
[0035]
Further, in the state shown in FIGS. 2A and 3B, the wiring guide member 16 moves further rearward than the proximal end side connection portion 15, so that the bent portion 13 a of the wiring material becomes the proximal end side connection portion. It is pulled backward from 15. Therefore, the bent portion 13a of the wiring member 13 remains low and does not swell greatly in the direction of the installation region 5, and the wiring member 13 does not hit the electronic component or the movable mechanism component in the installation region 5.
[0036]
Next, the wiring restricting member 17 exhibits a function of suppressing the bending of the wiring member 13. Between the moving side connection portion 14 and the proximal end side connection portion 15, the wiring member 13 has a bending portion 13a. However, the wiring regulating member 17 suppresses the bending portion 13a and the swelling of the bending portion 13a increases. To suppress. Moreover, since the wiring regulating member 17 moves together with the moving member 7, for example, when the moving member 7 moves backward as shown in FIG. 3B, the wiring regulating member 17 does not hinder the movement of the moving member 7. . In addition, the wiring restricting member 17 moves with the movement of the moving member 7, and restricts the bending portion 13a at a position that is optimal for suppressing the swelling. Therefore, the wiring member 13 does not hit the electronic component or the mechanical component in the installation area 5.
[0037]
In the present invention, even if only the wiring guide member 16 is provided and the wiring restriction member 17 is not provided, it is possible to prevent the bending portion 13a from being excessively moved by moving the bending portion 13a by the wiring guide member 16.
[0038]
However, as shown in FIGS. 1 to 3, if both the wiring guide member 16 and the wiring restricting member 17 are provided, the bending portion 13 a moved by the wiring guide member 16 can be restricted by the wire restricting member 17. As a result, the swelling of the wiring member 13 in the direction of the installation area 5 can be effectively suppressed.
[0039]
4A and 4B are partial side views showing an electronic apparatus having a moving member according to the second embodiment of the present invention.
In the electronic device shown in FIG. 4, the moving state of the moving member 7 is the same as that of the embodiment shown in FIGS. However, in the configuration shown in FIG. 4, the arrangement of the wiring guide member 16 and the wiring regulation member 17 is opposite to that shown in FIGS. 2 and 3, and the wiring regulation member 17 is located behind the wiring guidance member 16. doing.
[0040]
Also in this embodiment, the wiring guide member 16 moves the bending portion 13a of the wiring member 13 as the moving member 7 moves. Therefore, as shown in FIG. 4A, the bent portion 13a is pulled backward to prevent the bent portion 13a from bulging. Although not shown in FIG. 4, the moving member 7 enters the region 4. The wiring member is not sandwiched between the moving member 7 and the bottom wall surface 2a. Further, as shown in FIG. 4B, even if the wiring member 13 passing over the wiring guide member 16 is long, the wiring restricting member 17 can suppress the swelling of the bent portion 13a.
[0047]
【The invention's effect】
As described above, in the present invention, when the moving member moves, the bending of the wiring member connected to the moving member can be regulated following the movement of the moving member. And the bulge of the bent portion of the wiring member can be prevented from hitting other electronic components and the mechanism portion.
