Reference numeral 25 in FIGS. 4 to 6 denotes a tension roller for preventing the slack of the toothed belt 16b and the synchronous deviation of the teeth.

The disc reproducing apparatus of the present invention has the above-mentioned structure, and its operation will be described below.

First, when the disk reproducing unit 13 shown in FIGS. 1, 5 and 7 is playing the disk 14 housed in the cabinet 11, the lid 12 is closed, and at this time, the lid 12 is closed. The disk reproduction unit section 13 and the disk reproduction unit section 13 have a positional relationship such that they face each other.

Then, if the half-open / close button 20 is pressed when changing various controls during a performance, the motor 15a rotates and only the lid 12 first starts to move. At this time, the convex full-closed detection ribs 12b arranged on the inner surface of the lid 12 move, the pressing due to the convex shape disappears, and the full-closed / full-open detection portion 24b of the lid 12 operates to turn from the on state to the off state. And the lid 1
2 rises to the position shown in FIGS. Immediately before this position, the half-open detection rib 12c presses the half-open detection portion 24a to be in the ON state, and the lid 12 continues to rise. Then, the half-open detection rib 12c moves, the convex-shaped pressure disappears, and the half-open detection portion 24a of the lid 12 works to turn off the state, and the motor 15a is stopped to enter the half-open state. In this half-opened state, the disc 14 cannot be attached or detached, but the control button 22 can operate a predetermined function. At the position shown in FIG. 10, the cam pin 13d is connected to the positive movement cam 15
Since it is guided by the circular arc-shaped groove 15ka of k, the disk reproducing unit 13 does not move in the housed position.

When the half open / close button 20 is pressed in the half open state, the motor 15a rotates in the opposite direction to slide the lid body 12 to the position shown in FIGS. 10 to 9 to put the lid body 12 in the closed state. At this time, first, the half-open detection rib 24c activates the half-open detection portion 24a, and then the full-close detection rib 12b activates the fully-closed / fully-open detection portion 24b, so that the half-open detection portion 24a is turned on and the full-closed state is reached. And the lid is closed.

Next, when the disc 14 is replaced after the performance is completed, the lid 12 is lifted by the rotation of the motor 15a by pressing the open / close button 17 from the state where the lid 12 shown in FIGS. 1, 5 and 7 is closed. Do it. Then, until the state shown in FIG. 11 is reached through the state shown in FIG.
Since the cam pin 13d is guided by the arcuate groove 15ka of the positive cam 15k, the disc reproducing unit 13 does not move in the housed position, but the lid 12 rises to the position shown in FIG. 12 through FIG. At this time, the cam pin 13d is guided by the arcuate groove 15kb of the positive-moving cam 15k, and the disc reproducing unit portion 13 comes out forward. And
After the state of FIG. 12 is reached, the pinion 15j and the arcuate rack 13b mesh with each other, and the disc reproducing unit portion 13 approaches the front as the lid 12 slides upward. At this time, the lid body 12 continues to move up while the half-open detection section 24a remains in the off state, and when the full-open detection section 24b is activated by the full-open detection rib 12d on the inner surface of the lid body 12, the lid body 12 is in the fully open state. , The motor 15a is stopped and the lid is opened as shown in FIG. In this state, the performance of the disc 14 is stopped, and the disc playback unit 1
The disk 14 can be attached to and detached from the third turntable 13a.

When the open / close button 17 is pressed in this open state, the motor 15a rotates in the opposite direction and the lid 12 is closed. At this time, the fully closed / fully opened detection unit 24b is once turned off from the on state in the open lid state by the fully opened detection rib 12d and the fully closed detection rib 12b, and then is turned on again immediately before the fully closed state. . On the other hand, the half-open detection unit 24a changes from the OFF state in the open state to the ON state in the half-open state section. Both such detectors 24a, 24
The motor 15a is stopped when it is determined to be in the fully closed state by the signal of b.

In the above description, the lid 12 has been constructed so as to slide vertically along the front surface of the cabinet 11. However, the lid 12 is provided in the main body of the cabinet 11, for example. It may be configured to rotate in the vertical direction about the rotation fulcrum and slide.

Further, the turntable 13a provided in the disc reproducing unit portion 13 is shown in a state in which the disc reproducing unit portion 13 is in a state of being inclined forward with its front end downward when the disc reproducing unit portion 13 is protruding forward. The rotation angle of the disc reproducing unit section 13 may be set and controlled so that the turntable becomes horizontal in the ejected state.

[0026]

As described above, according to the present invention, the vertical type cabinet which is opened as a whole from the closed state is slid upward from the closed state on the front surface of the cabinet formed in the vertical type. A lid is provided and the cabinet is stored so as to face the lid when the lid is closed, and when the lid is opened, the disc playback unit is installed under the lid so that the disc playback unit can be moved to the front. Since the disc playback unit is pushed forward, the disc can be attached to and detached from the turntable. It can be made small and can be installed in places with a narrow depth.
