Abstract

PURPOSE:To simplify the operation with no limitation for the size of a motor in its radius direction, by setting a disk driving motor at the side opposite to a pickup device and at the same time at the cover side of the main body of a reproducer. CONSTITUTION:A disk driving motor 23 is clamped with holding a disk 21 at the side opposite to a pickup device 20 and at the side of the cover 26 of a reproducer main body 24. As a result, the motor 23 receives no limitation for the size of its radius direction. In addition, the space at the lower side of the disk 21 is never occupied by the motor 23. Thus, the operation of reproduction is simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disc-shaped information recording carrier reproducing apparatus C (hereinafter referred to as a disc play).

All conventional disk plays have a configuration as shown in FIGS. 1 and 2. That is, in the one shown in FIG. 1, a pickup device (2) is provided so as to come into contact with the disk (disc-shaped information storage carrier) (1), and the disk (1) is placed on top of the motor (3). After the is placed,
Pickup moving along slide rail (4) K°
The information on the disc (1) is reproduced by the device (2). In the one shown in Fig. 2, the pickup device (2) is provided so as to be in contact with the upper surface of the disk aυ, and the pickup device (2) is moved along the slide rail (to) the disk (
The disc (2) was moved toward the outer circumference of the disc (2) and placed on the motor α◆, and the pickup device (b) was moved over the disc (b) again before playback was performed.

Therefore, in the one shown in FIG. 1, the pickup device (2)
When the motor (
3), the diameter of the motor (3) is limited, which results in the inability to use a motor with sufficient torque and the disadvantages of a long start-up time for the player. Since the motor (3) is provided below the disc (1), there is a drawback that space inside the player is occupied. Furthermore, in the case of the one in Fig. 2, in order to place the disk Qη on the motor α◆, the pickup device (6) must be moved in the direction of the outer circumference of the disk a'D before the disk loading lid. However, it has the disadvantage that it takes a long time to play, and there is a motor Q on one side of the disc (1).
4, there was a drawback that the space inside the lure was occupied.

The present invention has been made in order to deal with a certain problem, and includes a cover that connects a motor that rotates a disk to the side of the disk opposite to a pickup device that plays back information signals from the disk, and that covers the main part of the playback device. The pickup device is provided on the side of the disk, and the pickup device is moved in the radial direction of the disk.

The present invention will be explained below based on drawings showing embodiments.

First, in FIG. 3 showing the first embodiment, gIJ is a pickup device provided so as to be in contact with the lower surface of the disk (G11), and while moving along the slide tray (G11), it picks up information on the disk (2). Play. The rock is a motor located above the disk ■, and this motor (
2) The lower sK Dinuk is clamped with a suitable flat membrane to drive the disc υ to rotate.

In this case, since the motor ■ is located above and the pickup device (E) is located below, holding the disk (2), the radial size of the motor is not limited, and the space of the disk @υ is not occupied by the motor as before.

As is well known, by increasing the radial size of the motor, it is possible to easily generate all the torque. Therefore, in the present invention, since there is no restriction on the radial size of the motor, the start-up of the player can be easily increased. You can easily save time.

FIGS. 4 and 5 show specific configuration examples of the present invention.

The disc 30 is inserted into the lower club provided on the negative side of the playback device.
1 is placed on the damper (2), the cover (to) is closed on the main body in the direction of the arrow in Fig. 4, and the cover (e) is placed on the main body (goods).
The disk drive υ is held between the clamper (c) and rotated by a crank (b) housed in the lower part of the motor cover provided on the side. Then the main body-
A pickup device 4 provided at 111 moves along the slide tray I and plays the disc eD from the bottom.

The motor member is housed in the cover member through an elastic member (2), and the clamper @@ has a disc Q due to the elasticity of the first shaft of the motor (2) and the elastic member (2).
υ is pressed and the disk (2) rotates.

FIG. 6 shows an embodiment of the clamper (c). In Fig. 6, the disk Q1 is placed on a clamp member (7) that is urged upward by a spring holder. 7 (to) is a clamper booth, which is configured to have a four-way rotation function by a bearing (2). The disk 4 is rotated by being pressed against the crankshaft case G (n side) by a clamper provided at the motor stop.

FIG. 7 shows another disc-to-layer configuration, ie, a front-operated version. The motor is housed in a cover (E) provided on the front side of the disc 4Vi playback device main body, and is fixed by a clamper rod, and after the cover (E) is closed in the direction of the arrow in Figure 7, Information on the disc (2) is reproduced by a pickup device that moves along a slide rail (2) provided on the main pay side.

The present invention can be implemented as described above, and by installing the motor for rotating the disk on the opposite side of the disk from the pickup device and on the cover side, the conventional disk drive - The disadvantages of - can be overcome. That is, (1) the radial size of the motor is not restricted;

C) The space on the side where the pickup device is provided becomes larger.

■ Easy to operate when playing discs.

It is possible to realize a disk flare with the following advantages and has great practical value.
