ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to disk playback devices adapted to draw a disk into a cabinet for playing back the disk.
BACKGROUND OF THE INVENTION
FIG. 28
shows a known disk playback device (see Examined Japanese Utility Model Publication No. 121545/1991). In the following description, the direction inward of the device will be referred to as the rear, and the direction toward which the disk is taken out of the device as the front.
The known device comprises a cabinet
1
having an open front side, and a slide panel
4
retractably movable out of the cabinet
1
for placing a disk D thereon. Provided inside the cabinet
1
is a clamp
8
movable upward and downward and positionable over the disk D for holding the central portion of the disk.
The cabinet
1
is formed in each side wall thereof with a guide slot
12
extending horizontally and having fitted therein a slide pin
42
projecting from a side portion of the slide panel
4
. The disk D is placed on a recessed surface
40
provided by the upper side of the slide panel
4
. The disk D is loaded onto the slide panel
4
by first pulling out the panel
4
from the cabinet
1
to expose the recessed surface
40
and then placing the disk D onto the surface
40
.
When the disk is to be played back, the slide panel
4
is pushed into the cabinet
1
. The clamp
8
moves down to lightly hold the central portion of the disk D between the clamp and a turntable (not shown) on the slide panel
4
. The turntable rotates for playback.
With the conventional device, however, the disk can not be placed in position unless the slide panel
4
is pulled out to expose the recessed surface
40
entirely. This increases the distance from the opening of the cabinet
1
to the front end of the slide panel
4
. Accordingly, if there is some obstacle to the front of the cabinet
1
, the panel
4
fails to fully open, presenting difficulty in loading the disk.
Further, if the slide panel
4
is liable to backlash as accommodated in the cabinet
1
, the disk will not be positioned properly relative to the clamp
8
when the cabinet is subjected to an impact from outside. It is then likely that the disk will not be played back with good stability.
The disk playback devices of the type described include those having a front panel (not shown) which is closable for covering the front opening of the cabinet
1
. The front panel is opened and closed independently of the movement of the slide panel
4
.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a device of the type described wherein the slide panel is reduced in the length of projection when completely opened, the slide panel, as housed in the cabinet, further being prevented from backlashing.
The present invention provides a disk playback device wherein a slide panel
4
is fitted to a free end of a front panel
2
and a cabinet
1
, and is movable with the front panel
2
when the panel
2
pivots for opening and closing. The slide panel
4
is extended from the cabinet
1
with a disk support surface thereof facing upward when the front panel
2
is completely opened.
From the position wherein the slide panel
4
has already reached a rear end of a guide slot
12
, the front panel
2
is further rotated in the closing direction by an amount corresponding to a clearance in a hole
20
having a fitting pin
41
therein. This movement causes a spring member to press the fitting pin
41
toward the closing direction, pressing the slide panel
4
into contact with the rear end of the guide slotted portion
12
.
With the front panel
2
in its completely opened position, the slide panel
4
is inclined in a completely opened position and is exposed over the entire surface thereof. This shortens the distance from the front end of the slide panel
4
to the cabinet
1
, consequently diminishing the likelihood that an obstacle, if present to the front of the cabinet
1
, will hamper complete opening.
Further with the front panel
2
in its completely closed position, the slide panel
4
is pressed by the spring member into contact with the rear end of the guide slotted portion
12
and is thereby restrained from sliding inadvertently. This obviates faulty playback due to the backlash of the slide panel
4
′ even if an impact acts on the device from outside.
