DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device in which a movable member having a display member and / or an operation member housed in a case projects outside the case, or an optical head and a magnetic head which move in the case. The present invention relates to an electronic device having a moving member such as a moving member, and 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 the case to select and drive a plurality of recording media. .

[0002]

2. Description of the Related Art In a vehicle-mounted electronic device, a moving member having a display member such as a liquid crystal display device or a moving member having an operating member protrudes outward from a case from a state of being stored in the case. Moving, so that the moving member provided with the display member rotates outside the case,
There are screens in which the screen rotates in a direction that is easy for a passenger in the vehicle compartment to see. In an electronic device 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 a case.

In an electronic apparatus in which one of a plurality of recording media called a disk changer is selected to perform recording or reproduction on the recording medium, a moving member including a disk rotation driving unit and a head is provided with a moving member. It moves along the direction in which the recording media are arranged, and any one of the recording media is selected and driven by a mechanism in the moving unit.

As described above, in an electronic apparatus having a moving member that moves inside or outside of a case or inside a case, an electronic circuit provided in the case and the moving member are connected by a soft wiring member. 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]

In the electronic device having the moving member, the connecting portion between the wiring member and the moving member is connected to the moving-side connecting portion, and the connecting end of the wiring member on the opposite side is connected to the base-side connecting portion. Since the length of the wiring member is determined in a state where the moving member is farthest from the proximal connection portion, when the moving member moves toward the proximal connection portion, Deflection occurs in the material.

If the bending of the wiring member is set to a free state, the wiring member may be rubbed against the moving member being moved, or may be bent by being sandwiched between the moving member and the wall surface, leading to disconnection of the wiring member. is there. Alternatively, the bent portion of the wiring member may swell and hit another electronic component or a movable mechanism component adjacent to the moving area of the moving member, and as a result, the wiring member may be damaged.

To prevent the wiring member from swelling, it is conceivable to provide a wiring guide fixed inside the case. However, this wiring guide must be arranged at a position outside the moving area of the moving member. Therefore, it is difficult to reliably guide the wiring member that extends or bends due to the movement of the moving member. Further, if the wiring guide is disposed at a position outside the moving region of the moving member, the wiring member is forcibly bent at a position outside the moving region of the moving member, and excessive bending stress acts on the wiring member. Problems such as breakage and wiring damage are likely to occur.

The present invention has been made to solve the above-mentioned conventional problems, and it is possible to reliably guide a wiring member that extends or bends with the movement of a moving member, and that unnecessary bending stress does not act on the wiring member. It is another object of the present invention to provide an electronic device having a movable member that enables such routing.

[0009]

SUMMARY OF THE INVENTION The present invention relates to a moving member that moves with a built-in electronic device or electronic component, and a soft wiring member that transmits power and / or signals between the moving member and an electric circuit.

According to the present invention, the wiring guide member follows the moving member and moves together with the moving member. The moving member,
When moving to the base side connection portion side, which is the connection portion on the electronic circuit side, the amount of bending of the wiring member increases, but the bending portion of the wiring member moves ahead of the moving direction of the moving member due to the movement of the wiring guide member. And moved. Therefore, the bent portion of the wiring member is not sandwiched between the moving member and an adjacent member such as a wall surface.

[0011] Next, the present invention provides a moving member which incorporates and moves an electronic device or an electronic component, and a soft wiring member for transmitting electric power and / or a signal between the moving member and an electric circuit. In the electronic device having the wiring member, a wiring regulating member that moves together with the moving member along the moving direction of the moving member is provided, and the wiring regulating member is located outside a bent portion of the wiring member. The bulging of the bent portion is suppressed by the movement.

In the present invention, when the moving member moves toward the base end side connection portion of the wiring member and the bending portion of the wiring member increases while moving, the wiring that follows the movement of the bending portion is provided. The bending of the wiring member is suppressed by the restricting member, and it is possible to prevent the bent portion from expanding significantly. Therefore, it is possible to prevent the wiring member from flexing and expanding and coming into contact with another adjacent electronic component or movable mechanism component.

[0013] The present invention further provides an electronic device having a moving member that moves with a built-in electronic device or electronic component, and a flexible wiring member that transmits power and / or signals between the moving member and an electric circuit. In the device, a wiring guide member and a wiring regulating member that move together with the moving member along the moving direction of the moving member are provided, and the wiring guiding member is located inside a bent portion of the wiring member, and The member is located outside the bent portion of the wiring member, the bent portion is moved by the movement of the wiring guide member, and the bulging of the bent portion is suppressed by the movement of the wiring regulating member. Is what you do.

According to the present invention, when the moving member moves to the connection side end, the bent portion of the wiring member is pulled backward by the wiring guide member, and the bent portion is sandwiched between the moving member and the wall surface. In addition, the expansion of the flexure of the wiring member moved by the wiring guide member is suppressed by the wiring restriction member.

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 of the wiring member on the side opposite to the moving member is a base-side connecting portion, When the member is moving in a direction away from the proximal connection portion, the wiring guide member is located between the movable connection portion and the proximal connection portion, and the moving member is connected to the proximal end. When moving toward the side connection portion or beyond the base side connection portion, the wiring guide member is effective when moving to the rear of the base side connection portion.

When the moving member moves toward the connection side end, the wiring material accumulates in the base end side connection portion and forms a bend at that position, but the wiring guide member is located behind the base end side connection portion. As a result, the bending portion generated near the proximal connection portion is pulled rearward from the proximal connection portion by the wiring guide member. Therefore, excessive bulging of the bending portion does not occur near the base end side connection portion.
