Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information processing device that reproduces information from a disc, and more particularly to a motor mounting structure that allows adjustment of the mounting orientation of a turntable driving motor of the device. It is something.

[Prior art]

Conventionally, as this type of device, for example, Utility Model Application No. 57-3831
There is one shown in Publication No. 2. FIG. 4 is a schematic vertical cross-sectional view showing the recording disk reproducing apparatus disclosed in the above-mentioned publication. In the figure, 1 is a disk, 2 is a turn-chill pull on which the disk 1 is placed, and 3 is a rotary shaft 3a with the above-mentioned The turntable 2 is fixed to a motor that rotates the disk 1, and the motor 3 is housed in a flanged casing 4 having a flanged portion 4a. 5 is a chassis, and the chassis 5 is formed with a recess 5b having a motor mounting hole 5a, and the flanged casing 4 has a flange 4a in the recess 5b with three setscrews 6a, 6b, and 7. Fixed and installed. Note that the set screws 5a, 6b, 7
A leaf spring 8 is inserted in a compressed state between the flange 4a and the recess 5b of the chassis 5 so that the screwing amount of only one set screw 7 can be varied. It is configured to be screwed onto the flange 4a from the lower surface side. On the other hand, reference numeral 9 denotes a pickup device for reproducing information signals from the disc 1, which faces the 1n information recording surface of the disc 1 at a predetermined interval and is movable in the radial direction.

Next, the operation of the conventional device configured as above will be explained. A disk 1 is placed on a turntable 2, and is driven to rotate together with the turntable 2 by a motor 3. Information signals from the disc 1 are reproduced by a pickup device 9 that runs parallel to the chassis 5 by means of guide means (not shown). Here, in order to obtain a good reproduction signal by the pickup device 9, the pickup device 9 must always maintain a predetermined distance from the disk l.
In order to make the rotational surface of the turntable 2 on which the pickup device 9 is placed exactly parallel to the running surface of the pickup device 9, that is, the chassis 5, it is necessary to adjust the mounting attitude of the motor 3 with respect to the chassis 5. In the above conventional device, as described above, the flanged casing 4 of the motor 3 is attached to the chassis 5 with three set screws 5a, 6b, and 7, and the set screw 6a
.

The screw 6b is tightened until it is fully tightened, and the screwing amount of the set screw 7 is variable via the leaf spring 8, so by adjusting the screwing amount of the set screw 7 from the bottom of the chassis, the motor The mounting posture of No. 3 can be adjusted as appropriate. For example, by increasing the screwing amount of the set screw 7, the temporary spring 8 is compressed, and the turntable 2 is tilted together with the motor 3 in the direction of arrow A in the figure, and by decreasing the screwing amount, the restoring force of the leaf spring 8 is It can be tilted in the direction of arrow B in the figure.

[Problem that the invention seeks to solve]

With the above configuration, the conventional device can adjust the mounting position of the motor. However, as mentioned above, the motor 3 with the characteristics of this device having the flanged casing 4 is required, which increases the cost of the motor and increases the flange of the motor 3. Since the plate spring 8, which is a separate component, is inserted between the attached casing 4 and the chassis 5 and the set screw 7 is tightened, there is a problem in that it takes a long time to assemble the device.

The present invention has been made to solve these problems, and allows the use of a ready-made, inexpensive motor with a cylindrical casing, without the need for inserting separate parts during assembly.
The purpose is to obtain a device that can be assembled in a short time.

[Means for solving problems]

The information processing device according to the present invention is provided with a first motor which faces a mounting member for mounting the motor onto the chassis via an extension of the moving path of the pickup device, and which is fixed to the chassis. a second fixing piece; a screw mounting piece disposed on an extension of the movement path of the pickup device, spaced apart from the chassis by a certain distance, and screwed to the chassis in an adjustable manner; and an elastic piece that comes into contact with the chassis.

[Effect]

In the present invention, the motor is attached to the chassis by the first and second fixing pieces of the mounting member and the screw mounting piece, and the screw mounting piece resists the elastic force of the elastic piece protruding from the screw mounting piece. By adjusting the screwing amount of the screw provided in the motor, the mounting posture of the motor can be adjusted in eight rotations.

〔Example〕

Hereinafter, the present invention will be explained by showing examples. 1 and 2 are a perspective view and a side view of essential parts thereof showing an embodiment of the present invention, and the same or corresponding parts as in the conventional example shown in FIG. In each figure, 1
0 is a motor for driving the turntable 2, a ready-made cylindrical casing sweater is used, and the turntable 2 is attached to the rotating shaft 103. 6 1) is a mounting member for attaching the motor 10 to the chassis 5. This motor mounting plate is made of a plate material on which the rotating shaft side end surface 10b of the motor 10 is mounted. The motor mounting plate 1) is provided with a pickup device 9 that extends approximately in the radial direction of the disk 1.
The first . Second fixing pieces 12a and 12b are provided, and a screw mounting piece 13a having a setscrew 7 which is spaced a certain distance from the chassis 5 and screwed onto the chassis 5 is provided on an extension of the moving path of the pickup device 9. A movable piece 13 is provided that protrudes from both ends of the mounting piece 13a, extends obliquely toward the chassis, and has a pair of elastic pieces 13b whose tips abut against the chassis 5. Note that the set screw 7 is attached to the screw mounting piece 13a.
It is screwed onto the chassis 5 from the top side.

The present embodiment is constructed as described above, and the first. The setscrews 6a and 6b for fixing the second fixed pieces 12a and 12b to the steering wheel 5 are tightened until they are tightened, and the screw attachment piece 13a of the movable piece 13 is fixed to the elastic piece 13b.
Since it is spaced a certain distance from the chassis 5 against the elastic force of The mounting orientation of the motor 10 can be adjusted as appropriate. For example, by increasing the screwing in of the set screw 7, the elastic piece 13b is compressed and the turntable 2 tilts in the direction of arrow C in the figure together with the motor lO, and by decreasing the screwing amount, the restoring force of the elastic piece 13b It can be tilted in the direction of the arrow in the figure.

In the above embodiment, the movable piece 13 of the motor mounting plate 1) was constructed by extending the elastic piece 13b from the screw mounting piece 13a so as to be inclined toward the chassis. As shown, the screw mounting piece 1 of the movable piece 13
3a and the elastic piece 13b on the same plane, the elastic piece 1
3b, the chassis 5 is provided with a cut-and-raised piece 5C, and the tip of the elastic piece 13b is configured to abut on this cut-and-raised piece 5C. In order to further stabilize the position of the mounting piece 13a, the number of elastic pieces 13c may be increased as shown in the figure. Furthermore, elastic piece 13
It is possible to achieve the original purpose with c alone.

(Effects of the Invention) As explained above, according to the information processing device according to the present invention, a screw mounting piece having an elastic piece is provided in a part of the motor mounting member, and the screwing amount of the screw that presses the screw mounting piece is Since the attitude of the motor is adjusted by changing the position of the motor, the motor mounting attitude can be adjusted without using a special motor for this device or without inserting separate parts for adjustment. This has the advantage that an inexpensive off-the-shelf motor can be used and the assembly time of the device can be shortened.
