[Prior Art]

 Conventionally, there is a technology in which a turntable supports a disc horizontally and a pickup table is moved to the upper and lower faces of the disc to read information on the upper and lower faces of the disc. In this case, the FFC connecting the flexible holder to the connector attached to the pickup base allows the movement of the pickup base, so that the FFC is attached with a sufficient length. For this reason, there was a problem that the FFC drooped when the pickup table got on the turn carriage to prevent the above-mentioned boarding, or the FFC drooped on the deck chassis was rubbed to damage the FFC.

Therefore, conventionally, as shown in FIG. 9, a torsion spring 20 is attached to the flexible holder 15, and the FFC 1 hung by the torsion spring 20 is wound around the flexible holder 15 to solve the above-mentioned problem. In FIG. 9, reference numeral 10 is a pickup stand, reference numeral 11 is a pickup, and reference numeral 14 is a turn carriage.

[0004]

[Problems to be solved by the device]

 However, the repulsive force of the torsion spring 20 increases as the pickup base 10 moves away from the turn carriage 14, and the moving load of the pickup base 10 increases, which prevents smooth operation and causes a failure. .

The present invention has been made in view of the above circumstances, and an object of the present invention is to mount an FFC in which the FFC slop can be satisfactorily wound into the flexible holder without changing the moving load of the pickup base. There is provided a disc player having a structure.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a disc player equipped with a turn carriage for moving a pickup to the upper and lower sides of the disc. One end of the disc player is connected to a connector attached to a pickup table and the other end is connected to the turn. It is characterized in that the vicinity of the connector connection end of the FFC that is rolled up in the flexible holder attached to the carriage is attached upward along the pickup base.

[0007]

[Action]

 Since the present invention has the above-mentioned configuration, the FFC itself has an elastic force that causes an upward force to act near the connector connection end of the pickup table, and the middle portion of the FFC floats without contacting the chassis. Supported by the state. Further, when the pickup table is mounted on the turn carriage, the elastic force acts so as to press the intermediate portion of the FFC against the turn carriage and also to wind the FFC around the flexible holder.

[0008]

Embodiment Hereinafter, the present invention will be described in detail based on an illustrated embodiment. 1 to 3 show the mounting structure of the FFC on the pickup side. The FFC 1 has one end connected to a connector 3 attached to the pickup substrate 2, and a portion near the one end thereof is attached upward along the side wall 4a by a spring member 5 fitted to the side wall 4a of the pickup base 4. ing. The substrate 2 and the base 4 compose a pick-up base 10 to which a pickup (not shown) is attached, and a bearing hole 6 is formed in the base 4 so as to be slidably fitted in the pickup rail ( (See FIG. 3).

The spring member 5 is formed by bending a spring wire into a predetermined shape as shown in FIG. That is, the spring member 5 is roughly formed of fitting portions 5a, 5a bent on both sides in a U-shape, and a supporting portion 5b connecting the open ends of the fitting portions 5a, 5a. In this case, the support portion 5b is formed so as to connect the one end 5c of the opening end of the fitting portion 5a to the end portions bent slightly outward. Further, the other end 5d of the opening end of the fitting portion 5a is formed by obliquely bending so as to be located above the opening of the fitting portion 5a. The spring member 5 is attached by fitting the fitting portion 5a to the side wall 4a of the pickup base, and after fitting, the other end 5d of the fitting portion and the bottom portion of the fitting portion 5a prevent the spring member 5 from coming off.

The vicinity of one end of the FFC is attached upward by the spring member 5 attached as described above. That is, the FFC 1 has one end connected to the connector 3 attached to the pickup substrate 2 as shown in FIG. 1, the one end side thereof is bent along the side wall 4a of the pickup base, and the spring member is supported. It is attached by passing it between the portion 5b and the side wall 4a. As a result, the vicinity of one end of the FFC 1 is supported by the support portion 5b of the spring member and is attached upward.

As shown in FIG. 5, the pickup base 10 to which the pickup 11 is attached has a bearing hole 6 slidably fitted into a pickup rail 12 and is attached to a lower pickup guide body 13. At this time, the other end side of the FFC 1 is connected so as to be wound around the flexible holder 15 attached to the turn carriage 14. FIG. 5 shows the lower half mechanical portion of the disc player. In this disc player, the upper pickup guide body and the pickup rail are similarly provided in the upper portion of the disc player. The pickup table 10 can be moved to the upper and lower surfaces of a disc (not shown). In FIG. 5, reference numeral 16 is a tilt adjusting fulcrum shaft, and reference numerals 17 and 18 are spherical shapes for fitting the bearing hole 6 of the pickup base 10 when the pick-up base 10 is mounted on the turn carriage 14 to guide the mounting. It is a guide body, and reference numeral 19 is a chassis.

Next, the operation of this disc player will be described. In FIG. 5, the pickup table 10 is located at a position where information on the lower surface side of the disc is read. At this time, the FFC 1 is in the state of being pulled out from the flexible holder 15 to the longest, but the elastic force of the FFC 1 itself exerts an upward force on the portion attached by the spring member 5, and the middle portion thereof is attached to the chassis 19. It is supported in a floating state without contact.

FIGS. 6 and 7 show a state in which the pickup base 10 has moved from the reading position (FIG. 5) on the lower surface of the disc to get on the turn carriage 14, and the floating part of the intermediate portion of the FFC 1 floats at any of the moving positions. Is maintained, and at the position close to the turn carriage 14 (FIG. 7), the elastic force of the FFC 1 itself pushes the middle part of the FFC 1 against the turn carriage 14 and the roll holder 15 is rolled up. Is prepared.

FIG. 8 shows a state in which the pickup base 10 is mounted on the turn carriage 14. In this state, the middle portion of the FFC 1 is wound into the flexible holder 15 by the upward elastic force of the FFC 1 itself on the pickup table 10 side.

As described above, in the disc player having the mounting structure for the pickup base 10 side of the FFC 1 of the present embodiment, the external force along the moving direction of the pickup base 10 is not applied to the FF C1, so that the pickup base is not affected. Since the moving load of 10 does not fluctuate and the middle portion of the FFC 1 is supported in a state of floating from the chassis 19, the FFC 1 does not rub against the chassis 19 when the pickup base 10 moves.

The present invention is not limited to the above-described embodiments and includes the following modifications. That is, as a mounting tool for mounting the FFC 1 upward, a leaf spring may be used instead of the spring member 5, or a simple stopper having no spring action may be used.

[0017]

[Effect of the device]

 According to the present invention, as described above, since the vicinity of the connection end on the pickup base side of the FFC is attached upward along the pickup table, the upward elastic force of the FFC itself acting on the vicinity of the connection end causes the FFC to move upward. The intermediate portion can be supported in a floating state without contacting the chassis, and the FFC can be smoothly wound into the flexible holder when the pickup base is loaded on the turn carriage. As a result, the present invention can provide a disc player which does not cause a load fluctuation along with the movement of the pickup, can obtain a smooth operation, and does not damage the FFC itself.
