JPH10222908A - Disk player having a rotating disk tray - Google Patents

Abstract

PROBLEM TO BE SOLVED: To eliminate instability due to a sliding operation along a guide rail and realize smooth loading and unloading operations by rotatably combining a disk tray having a turn-table and an optical pickup with a housing and performing accommodating and ejecting operations through rotation with respect to the housing. SOLUTION: A disk tray 120 includes a turn-table 130 and an optical pickup 140, and is rotatably combined with a housing 110 via a main hinge axis 111 provided in its peripheral portion. The disk tray 120 rotates around the main hinge axis 111 to realize accommodating and ejecting operations with respect to the housing 110. A torsion spring 150 engaged with the main hinge axis 111 energizes the disk tray 120 with its elasticity in its ejecting direction. A rocking lever 165 is allowed to be engaged with a rocking projection 124 to fix the disk tray 120 at an accommodating position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the attached drawings. Referring to FIGS. 2 and 3, the disc player according to the present invention includes a disc tray 120 on which a disc (not shown) is seated and hinged so that the disc can rotate in and out of the housing 110.
including. The disc tray 120 is provided with a turntable 130 on which a disc is placed and an optical pickup 140 for recording / reproducing information on / from the disc. The optical pickup 140 has an objective lens 141 for focusing light emitted from a light source (not shown) on the disk. Also, the optical pickup 140 has a disc tray 120.
Reciprocates along a guide rail (not shown) provided on the lower surface of the.

According to a feature of the present invention, the disk tray 120 is provided with a main hinge shaft provided at an edge of the housing 110.
It is connected rotatably around 111. Therefore,
The disc tray 120 is housed in or taken out of the housing 110 by rotating about the main hinge shaft 111. The disc tray 120 is urged in a counterclockwise direction so as to be taken out of the housing 110 by an elastic member such as a torsion spring 150 fitted on the main hinge shaft 111. That is, the torsion spring
One end of the first projection 11 is protruded into the housing 110.
2 and the other end is supported by a second projection 122 projecting from the lower surface of the disc tray 120.

Further, in the disc player of the present invention, a locking unit for fixing the disc tray 120 while the disc tray 120 is housed in the housing 110, and releasing the locking of the disc tray 120 by the locking unit. Unlocking unit. The locking unit includes a locking protrusion 124 provided on the disc tray 120,
When the disc tray 110 is received in the housing 110, a locking lever 165a formed at one end of the hook 165a for locking the locking protrusion 124 is formed.
165 incl. The locking lever 165 is connected to the housing 11
The locking projection 124 is urged by a spring 180 so that the locking state of the locking projection 124 is maintained. Also, the hook 165a has an inclined surface 16 for guiding the locking protrusion 124 smoothly.
It is desirable that 5b be formed. Therefore, when the leading end of the disc tray 120 is pushed to receive the disc tray 120 into the housing 110, the locking projection 124 pushes the inclined surface 165b to rotate the locking lever 165 in the direction of the arrow in FIG. The locking protrusion 124
Locking lever 165 biased by spring 180
Hook 165a.

The unlocking unit includes a solenoid driver 160 mounted on the housing 110 and having an output end 162 connected to the locking lever 165. The solenoid driver 160 has a disk tray.
The switch 170 is electrically connected to a switch 170 on a panel 125 provided on the entire surface of the panel 120. By operating the switch 170, the locking lever 165 is rotated to release the locking of the hook 165a by the locking projection 124.

An auxiliary locking release unit is provided in case the solenoid driver 160 is not properly operated due to a power failure or malfunction. The auxiliary unlocking unit includes a bar 176 that is reciprocally movable with respect to the housing 110 as shown, and pushes the other end 165c of the locking lever 165. One end 176a of the bar 176 faces the through hole 126 formed in the panel 125, and the other end 176c is the other end of the locking lever 165.
Meets 165c. Therefore, the through hole 126 is
When the one end 176a of the bar 176 is pushed, the locking lever 165 is rotated by the bar 176, and the locking of the locking projection 124 is released. The locking unit, the unlocking unit, the auxiliary unlocking unit, and the like that can be used in the disc player according to the present invention are not limited to the embodiment, and various modifications may be applied.

On the other hand, the rotation range of the disk tray 120 is restricted by the locking projection 128 formed on the disk tray 120 and the stopper 118 which the locking projection 128 engages when the disk tray 120 rotates to the outside. Is done. As shown in FIG. 5, the stopper 118 has
8 is formed with a locking groove 118a to be sandwiched. The stopper 118 is made of a flexible material.
8 is caught in the locking groove 118a or the stopper
One end of 118 is elastically deformed in the direction of the arrow. Therefore, the stopper 118 is provided on the disk tray 12 taken out so that the locking projection 128 is not easily detached from the detent groove 118a.
Keep 0 stable.

As an alternative, a stopper for locking the locking projection 124 without the locking projection 128 can be employed. The housing 110 is provided with curved guide rails 11 along the moving path of the disc tray 120.
9 are provided. As shown in FIG. 4, the lower surface of the disc tray 120 is provided with a raised portion 129 that makes point contact with the guide rail 119. Therefore, the disc tray 120 has a relatively low frictional resistance,
Can be stored and removed from / to zero.

The operation of storing and removing the disk tray of the disk player having the above-described structure according to the present invention will be described. As shown in FIG. 2, when the disc tray 120 is stored in the housing 110, the locking projection 124 is locked by the hook 165a.

As shown in FIG. 3, when the switch 170 is pressed, the locking lever 165 is rotated while the solenoid driver 160 is operated. Then, the locking projection 124 is pulled out of the hook 165a, whereby the disk tray 120 biased by the torsion spring 150 is taken out of the housing 110 while rotating.

At this time, the raised portion 129 (see FIG. 4) moves along the guide rail 119 while supporting the disk tray 120. When the disc tray 120 rotates, the locking projection 128 is sandwiched by the stopper 118, and the disc tray 120 is rotated.
The rotation of 120 stops.

[0018]

As described above, the disc player according to the present invention employs a disc tray which is rotatably accommodated in and out of the housing, so that the disc player has a relatively smooth disc shape as compared with the conventional sliding system. Loading and unloading are possible.
