Abstract

PURPOSE:To transfer and receive disks between a disk receiving body and respective housing positions with good accuracy and to prevent the damage of the disks by stopping the movement of the receiving body by the detection signal of a prescribed positioning slit and correcting the positional deviation of the receiving body by the detection signal of the slit for position correction corresponding to the positional deviation of the receiving body. CONSTITUTION:The number N of slits up to the N-th slit 13 corresponding to the housing position is set in a microcomputer (MC) when the housing position of the disk 10 is instructed to the MC. The receiving body 18 is then moved by a motor and the number of the pulses generated by the passage of the slit 13 between a light emitting diode D1 and photo TR T1 of the 1st photocoupler 23 is counted by the MC. The movement of the receiving body 18 is stopped when N is attained. The receiving body 18 is moved to the right or left side and the position thereof is corrected when the slit-less part of the slit plate 12 on the left or right side of the N-th slit exists between D1 and T1 by the positional deviation of the receiving body 18, the receiving body 18 is moved to the right or left side and the position is corrected. The position correction of the receiving body 18 via the 2nd photocoupler 24 is also possible.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention includes a disk storage body and a disk receiver for storing information recording disks in a plurality of storage positions, and a disk storage body that stores information recording disks in a plurality of storage positions. The present invention relates to a disk transfer device that transfers disks to and from a receiver.

[Conventional technology]

Generally, in a disc delivery device, information recording discs such as compact discs, video discs, or floppy discs are stored in parallel in each of a plurality of storage positions in a disc storage body, and are movably provided at each storage position in a disc receiver. In this case, it is necessary to accurately position the disc receiver in front of each storage position. Base number (BC
D), and the disk receiver is moved and positioned based on these addresses.

That is, if the number of discs stored is 64, at least 6 bits are required to represent 64 in BCD, so six slit plates are provided in the disc storage body, and each slit plate corresponds to each storage position. The disc receiver is provided with six 7-photocouplers that detect the slits of each slit plate, and each slit plate is detected based on the output signal Gζ of each photocoupler while the disk receiver is moving. Identifies the address represented by the BCD code, and identifies the address specified in advance.

At the time of detection, the movement of the disk receiver is stopped and the disk receiver is positioned at a designated predetermined storage position.

On the other hand, as a method for positioning the disk receiver, the disk receiver is provided with a slit plate in which positioning slits are formed parallel to each storage position, and a photocoupler is provided in the disk receiver to detect each positioning slit. The number of output pulses of the photocoupler due to the movement of the receiver from the reference position is counted, and when a predetermined number is counted, the movement of the disk receiver is stopped, and the disk receiver is positioned at a specified predetermined storage position. It is also being considered.

[Problem that the invention seeks to solve]

However, in the former case, a large number of slit plates and photocouplers are required, resulting in an increase in the size of the device, whereas in the latter case, only one slit plate and one 7-opto coupler are required, which reduces the size of the device. This has the advantage that it can be made smaller.

However, when the positioned disk receiver deviates from its predetermined storage position due to external force or voltage abnormality, in the former case, each storage position is represented as an absolute address, so the disk receiver can be moved at any time. By moving it slightly in that direction and identifying only one address of the nearby storage position, the absolute position of the disk receiver can be known, and the disk receiver can be easily corrected and returned to the predetermined storage position. However, in the latter case, since it is not known in which direction the disc holder is misaligned with respect to the predetermined storage position, it is difficult to know in which direction the disc holder should be moved to compensate, and it is difficult to move the disc holder to a new position. There is a problem in that the disk receiver must be returned to the reference position and the positioning operation to the predetermined storage position be performed again, which is very time consuming.

[Means for solving problems]

The present invention has been made with the above-mentioned points in mind, and is intended to simplify the configuration and make it possible to easily determine the direction of displacement when the disk receiver is displaced. a disk storage body that stores disks in parallel; a first slit plate provided at the front end of the storage body and having positioning slits formed in parallel to each storage position; a second slit plate provided parallel to the slit plate, having no slit on the outside of one end edge of each of the positioning slits, and having position correction slits formed on at least the outside of the other end edge;
a disk receiver that is movably provided in parallel with each of the storage positions and that transfers the disk to and from the storage positions; a moving means that moves the receiver; a position detection means for detecting the positioning slit in the storage position and outputting a detection signal; a stop command means for outputting a stop command signal to the moving means to stop the receiver according to the detection signal; and a stop command means for stopping the receiver by outputting a stop command signal to the moving means based on the detection signal a positional deviation detection means provided in a plane parallel to the disk including the position detection means and configured to detect the position correction slit and output a detection signal; Move the receiver toward the one end edge.

and a correction command means for outputting to the moving means a correction command signal for moving the receiver toward the other edge when the detection signal is not inputted. .

[Effect]

Therefore, in this invention, there is no slit on the outside of one end edge of each positioning slit in the first slit plate, and a position correction slit is formed in the second slit plate at least on the outside of the other end edge, so that the positioning slit can be positioned at a predetermined storage position. The positioning slit is detected by the position detection means and a detection signal is output.
In response to the detection signal, a stop command signal is output from the stop command means to the moving means, the movement of the disk receiver is stopped, the disk receiver is positioned at a predetermined storage position, and when the disk receiver is displaced, the disk receiver is If the other end edge is deviated by a certain number of mats ζ, the detection signal is not input to the correction command means, but only the detection signal from the position correction slit detection from the position deviation detection means is input, and the disk receiver is If a correction command signal for moving the disk receiver toward the one edge side is output to the moving means, and the disk receiver is shifted toward the one edge side, the correction instruction means cannot receive the disk receiver without inputting either the detection signal or the detection signal. A correction command signal for moving the body toward the other edge is output to the moving means, and the positional deviation of the disk receiver is corrected.

) If a stop command signal is output to and received by the motor, the disk (1
0) is transferred, and the disk (I0) accommodated in the receptor θ barrel is re-determined by the stage.
Alternatively, when the receiver (+81) is positioned at the predetermined position described above, the first light emitting diode (Dl) and the transistor (T1) are connected to the coupler as shown in FIG. There is an N-th slit corresponding to the above-mentioned instruction input terminal, and a pulse is continuously inputted to the input terminal of the microcomputer (MC).

When the playback of the disc stored in the receiver (18) is completed as described above, the disc (10) is moved to the designated storage position. A determination is made as to whether the 'L pulse has been input to The transfer to the storage position is performed.

, before the microcomputer (MC) reaches step Sε, the receiver end deviates from its normal position due to voltage abnormality in the external force application system to the receiver (181, etc.), causing the first light emission of the 17th Otocoupler. When a first slit plate (1 slit) on the left or right side of the Nth slit (Is) is interposed between the diode (Dl) and the first phototransistor (Tl), the The process passes the determination in step S5 and proceeds to step S7, where a routine for correcting the position of the receptor α barrel is executed.

That is, in step S7, the microcomputer (MC) determines whether or not the L pulse is input to the input terminal (I2), and if the determination is YES in each case, the process moves to step S8.89, and the process proceeds to step S8. At this time, the microcomputer (MC) determines that the end of the receptor is shifted to the left with respect to the Nth slit (l), and the microcomputer (MC) moves the receptor (181) to the right. A correction command signal such as this is output to the motor to move the receptor α barrel to the right, and in step S9, the microcomputer (MC) moves the receptor α to the right side with respect to the Nth slit. A correction command signal is output from the microcomputer (MC) to the motor to move the receiver (+8) to the left, and the receiver end is moved to the left. Terminals (11) 12: The movement of the receptor (119) is continuously stored until a YES determination is made as to whether the L pulse has been input.

If the determination in step S10 is YES, in step 311 the microcomputer (MC) outputs a stop command signal to the motor to stop the movement of the receiver (Is), and then in step S12 the microcomputer (MC) MC) again determines whether the L pulse is input to the input terminal (11), and the determination is YE.
If S, the position correction of the receiver (181) is completed, and the next operation is performed in the same way as when passing step S5 with YES, that is, moving the disk (10) from the receiver (181) to the storage position. The transfer will take place.

If the result in step S12 is NO, it is assumed that the position correction of the receiver (country) has not been completed and the operations from step S7 onwards are repeated.

In the above embodiment, there is no slit on the left side of the left edge of each positioning slit Q31 when viewed from above in the second slit plate (I4), and there is a slit (13) on the left side and the right side of the right edge. Although a wider position correction slit (I5) was formed, there was no slit on the left side of the left edge of each slit 03), and a position correction slit was formed only on the right side of the right edge of the second slit plate (I4). It may be formed into
