First, when the disk reproducing unit 13 shown in FIGS. 1, 5 and 7 is playing a disk 14 stored in the cabinet 11, the lid 12 is closed. The disk playback unit 13 and the disk playback unit 13 have a positional relationship to face each other, and as shown in FIG. 9, both the fully open detection unit 20 and the half open detection unit 21 are in the ON state. When the cover 12 is closed, that is, when the full-open detection unit 20 and the half-open detection unit 21 are both in the ON state and the open / close button 17a is pressed, the motor 15a is turned off at the next output from the control unit 22 to the drive circuit 23. Body 12
Is controlled to rotate to the open state.

When the sound quality is adjusted during the performance, for example, when the half open / close button 17b is pressed, the signal is sent to the control means 22, where the driving circuit 2 is controlled based on this signal.
A signal is output to the motor 3 and the motor 15a rotates to first raise only the lid 12 to the position shown in FIGS. Immediately before the state shown in FIG. 10, both the full-open detection section 20 and the half-open detection section 21 change from the on state to the off state, and the control means 22 outputs a signal to the drive circuit 23 by this signal to stop the motor 15a. In this half-open state, the disk 14 cannot be attached or detached, but a predetermined function can be operated by the second operation button group 18. In the position shown in FIG. 10, the roller 13d is guided by the arc-shaped groove 15ka of the positive cam 15k, so that the disk reproducing unit 13 does not move in the stored state.

When the open / close button 17a is pressed in this half-opened state, a signal is sent to the control means 22, where a signal is output to the drive circuit 23 based on this signal, and the motor 15a rotates in the opposite direction and the cover 15 The body 12 is slid to the position shown in FIGS. 10 to 9 to bring the lid 12 into the closed state. At this time, both the full-open detection section 20 and the half-open detection section 21 change from the off state to the on state, and the control means 22 outputs a signal to the drive circuit 23 by this signal to stop the motor 15a.

Next, when the disc 14 is replaced after the performance is completed, the cover 12 is raised by the rotation of the motor 15a by pressing the open / close button 17a from the state in which the cover 12 shown in FIGS. 1, 5 and 7 is closed. I will do it. Then, through the state shown in FIG. 10 described above, until the state shown in FIG. 11 is reached, the roller 13d is in the arc-shaped groove 15ka of the positive cam 15k.
, The disc reproducing unit 13 does not move in the stowed position, but when the lid 12 is raised to the position shown in FIG. 12 through FIG. 11, the roller 13d is rotated by the circle of the positive cam 15k. Guided by the arc-shaped groove 15 kb, the disc reproducing unit 13 protrudes forward. After the state shown in FIG. 12 is reached, the pinion 15j meshes with the arc-shaped rack 13b, and the disk reproducing unit 13 slides forward along with the lid 12 sliding upward. At this time, the control unit 22 determines that the full-open detection unit 20 is turned on while the half-open detection unit 21 remains off.
Is detected, it is determined that the lid 12 is fully opened,
The control means 22 outputs a signal to the drive circuit 23 to stop the motor 15a. In this state, the disk 14
Is stopped, and the disk 14 can be attached to and detached from the turntable 13a of the disk reproducing unit 13.

When the open / close button 17a is pressed in this open state, a signal is sent to the control means 22, where a signal is output to the drive circuit 23 based on this signal, and the motor 15a rotates in the opposite direction. The lid 12 is brought into a closed state. At this time,
The full-open detection unit 20 is once turned off from the on state and then turned on again. On the other hand, the half-open detection unit 21 is turned on from the off state. 15a is stopped.

As described above, according to the present invention, the cabinet is formed in a vertical shape as a whole and slides upward from the closed state along the front of the cabinet to open the cabinet. A lid is provided, and the cabinet is housed in the cabinet so as to face the lid when the lid is closed, and when the lid is opened, a disc playback unit is installed movably so as to protrude forward below the lid. However, since the disc playback unit is configured so that the disc can be attached to and detached from the turntable with the disc playback unit protruding forward, the depth of the device body can be reduced without impairing the operability when attaching or detaching the disc. It can be small and can be installed anywhere.

Further, since the second operation button group is provided so that the cover is covered when the cover is closed but is exposed when the cover is half-opened, the possibility of erroneous operation is reduced.
