2. Description of the Related Art FIG.
8. As shown in FIG. 19, a disk storage magazine (610) is rotatably provided on the base chassis (600), and the magazine (61) is provided.
The two playing sections (630) (630) and 1
There has been proposed a device provided with two charging / discharging sections (620) (Japanese Patent Application Laid-Open No. 4-57248).

[0003] A disc holding magazine (610), a playing section (630) (630) and a loading / unloading section for holding a disc.
The transfer member that transfers the disk to and from (620) generates static electricity due to friction with the disk when transferring the disk, and also charges the disk with static electricity. Further, the static electricity is accumulated in a disk holding groove in a magazine for accommodating a plurality of disks. Then, when the amount of accumulated static electricity reaches and exceeds the limit, the static electricity self-discharges to a ground circuit through an electronic circuit member arranged in close proximity, and a surge voltage due to the self-discharge is applied to an electronic circuit such as an IC.

On the other hand, recent ICs (Integrated Circuits) are formed with a structure in which the pattern intervals of IC internal elements are extremely small and close to a plurality of circuit patterns with the increase in the density of electronic technology. Therefore, the pn junction and the like of the IC internal element are relatively easily destroyed by a surge voltage caused by static electricity.

Therefore, in order to prevent device failure due to static electricity, usually, a method of removing electricity through a grounding circuit so that static electricity charged in a disk storage magazine or the like is not discharged to an IC or the like, or a component or an electronic circuit charged with static electricity In general, a method of protecting an IC or the like of an electronic circuit by shielding the electronic component or a method of forming a component from a material which does not easily generate static electricity is used.

However, there is no disk playing apparatus that stores a disk in a disk storage magazine in an upright state, and transfers the disk between the magazine and the disk loading / unloading section and playing section. The static electricity accumulated in the disc and the disc holding groove accommodated in the disc containing magazine (610), and the static electricity that is generated when the disc is transferred to and from the disc containing magazine (610). Destruction of electronic circuits such as ICs,
The above-mentioned prior art (Japanese Patent Application Laid-Open No. 4-57248) does not disclose any technical problem for preventing a device failure such as a malfunction or stop of the device.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and can eliminate static electricity accumulated in a disk and a disk holding groove accommodated in a disk accommodation magazine. When transferring between the disk storage magazine and the playing section, the static electricity generated by the friction between the disk and the transfer roller for transferring the disk can be neutralized, thereby preventing the device from malfunctioning or stopping or other device failure. This is to clarify the antistatic device.

At the lower end of the head mounting body (92), two leg shafts
(924) (924) is protruded, and the leg shaft (924) is
It is slidably fitted in the head-side opening / closing cam grooves (83) (83) established in (8).

The clamper (93) is a disk storage case (91).
A disk (933) with a built-in magnet at a position corresponding to the turntable (922) has a little extra space on a frame (932) supported by the pivots (931) and (931) at the lower end of the frame so as to be swingable. It is configured to fit in the state.

A leg shaft (934) protrudes from the lower end of the frame (932). The leg shaft (934) is slidable in a clamper-side opening / closing cam groove (85) formed in the slide plate (8). I'm stuck.

Since the playing operation after clamping the disk D is well known, the description is omitted.

The cam grooves (83), (83) and (85) of the slide plate (8)
Roller (61a) by means of a roller opening and closing cam groove (81) (82)
(62a) opening and closing, turntable (922) and clamper (93)
The timing of clamping the disc by the roller (61
a) (62a) sends out the disk D to the disk storage case (91), and after the disk is clamped by the turntable (922) and the clamper (93), the rollers (61a) and (62a) open to remove the disk. When releasing the clamping pressure and returning the disc D from the playing section (9) to the magazine (3) after the performance is completed, the rollers (61a) and (62a) are closed to sandwich the disc, and then the turntable is turned on. The timing is set so that the clamp of the disk D by the clamp (922) and the clamper (93) is released. That is, upon delivery of the disk, the disk
Since the rollers (61a) (62a) or the turntable (922) and the clamper (93) are constantly pressed and held from both sides, during the delivery of the disc, the playing device is tilted by lifting the playing device or the like. Also, the delivery of the disk can be reliably performed.

The rollers (61a) and (62) of the transfer device (6a)
The playing of the disk is performed with the disk fitted in a), but at this time, both rollers are separated from the transfer path of the disk and do not contact the disk, and there is no hindrance to the rotation of the disk.

As shown in FIG. 17, a clamp completion switch (SW7) and a clamp release switch (SW8) are provided along the transition path of the slide plate (8).

When the slide plate (8) advances toward the magazine (3) until the disk is clamped, the clamp completion switch (SW7) detects the protrusion (89) on the slide plate (8). Stop the clamp motor (M5).

Until the point where the disk clamp is released,
When the slide plate (8) is retracted, the clamp release switch (SW8) detects the protruding piece (89) and detects the clamp motor (M5).
To stop.

As described above, the performance of the disk is performed with a part of the disk being played fitted in the magazine (3). Therefore, the disk D is completely removed from the magazine (3). This can contribute to downsizing of the device as compared to a performance device for performing.

[Front Panel and Button Operation] (See FIGS. 2 and 8) As shown in FIG. 8, the front panel (2) has a slit (21) for loading / unloading a disc in the center and a display (28) in the upper left. ), A view window (29) in the upper right, an ON-OFF button (22), a play button (23), a stop button (24), an open / close button (2
5) A ten-key (26) consisting of ten key buttons numbered from 0 to 9 is provided.

[0098] Various kinds of displays are made on the display section (28) according to the mode of the performance device.

The viewing window (29) is for seeing the storage state and the rotation state of the disk on the magazine (3).
An illuminating lamp (not shown) provided inside the device shines the disk in a rainbow color, and an excellent decorative effect can be obtained.

The present invention is not limited to the configuration of the above embodiment, and various modifications are possible within the scope of the claims.
