Here, the engagement between the rack portion 31a of the rack 31 and the gear 41 is released, and the tooth-missing gear 38 integrated with the gear 37 naturally rotates during the rotation of the gear 37, so that the rack 31 and the rack 34 are integrated. Then, the rack portion 34b of the rack 34 starts to mesh with the gear portion 38a of the toothless gear 38, so that the contact portion 43a of the latch lever 43 is released from the protrusion 5d in the magazine 5 and The locking portion 43b of the latch lever 43 locks the pin 32 of the rack 31 so that the rack 31 is integrated with the rack 34. After that, since the rack 31 and the rack 34 are integrally moved in the arrow B ₁ direction by the rotation of the toothless gear 38, the cassette carrier 21 can also be naturally moved in the arrow B ₁ direction. In the rack moving mechanism 30, since the rack structure is separated into the rack 31 and the rack 34, there is an advantage that the length of the rack does not become long and neither the rack 31 nor the rack 34 protrudes toward the cassette holder 51.

[0047]   <Operation of cassette transport mechanism in magazine>   6 to 10 are schematic diagrams for explaining the operation of the cassette transport mechanism in the magazine. And move the cassette inserted in the cassette carrier to the cassette holder side. The operation order is shown. In addition, in the drawings of FIGS. 6 to 10, the front surface regulation member 13 and the rear The surface regulating member 17 illustrates the right side member shown in FIG. 5, and the left side in FIGS. 6 to 10. Is shown. In the following description, the left side will be the center, and the right side symmetrical to this The portions are shown centering on the shapes of the guide grooves 11a and 11b.

In FIG. 6, the cassette carrier 21 is located in the initial state similar to FIG. In FIG. 6, the cassette carrier 21 is stopped at the front in the insertion direction of the cassette 2 (shown by the chain double-dashed line). Further, since the sliding pin 18 and the engaging pin 19 projecting downward of the rear surface regulating member 17 on the insertion side are fitted in the V-shaped bent portion 11b ₁ of the guide groove 11b, as described above, the rear surface regulating member 17 is provided. Is urged to rotate in the counterclockwise direction (arrow direction) in the left side of the drawing by a spring 20 around the sliding pin 18 and the engaging pin 19 protruding downward. Therefore, since the regulation portion 17a of the rear surface regulation member 17 is avoided from the side surface 2d of the cassette 2, the cassette 2 can be attached and detached in the directions of the arrows E ₁ and E ₂ . On the other hand, the sliding pin 14 (14a, 14b) of the front surface regulation member 13 is fitted in the straight portion 11a ₁ of the guide groove 11a. As a result, the front surface 2a of the cassette 2 in the insertion direction can be contacted by the restriction portion 13a of the front surface restriction member 13, and when the cassette 2 is manually inserted into the upper surface of the cassette carrier 21 to the position shown in the drawing, the restriction portion The position of the front surface 2a is regulated by 13a. The rack moving mechanism 30 (FIG. 5) is driven by a detection switch (not shown) to reach FIG.

FIG. 7 shows a state in which the cassette carrier 21 is slightly moved in the direction of the cassette holder 51 (FIG. 5) (direction of arrow B ₁ ) by the rack moving mechanism 30 (FIG. 5) from the state of FIG. At this time, as described above, the cassette 2 inserted on the cassette carrier 21 between the racks 31, 31 moves together with the cassette carrier 21. That is, the cassette 2 provided with a leaf spring member for gripping both sides 2c and 2d of the cassette 2 or a rubber member or the like for gripping the cassette 2 can move integrally with the cassette carrier 21. Here, when the cassette carrier 21 starts to move in the direction of the arrow B ₁ , the front surface 2a of the cassette 2 which moves integrally with the cassette carrier 21 first pushes the restriction portion 13a of the front surface restriction member 13, whereby the front surface restriction member 13 is moved. It slides in the direction of arrow B ₁ along the straight portion 11a ₁ of the guide groove 11a. Further, from a predetermined position on the way of movement of the cassette transport body 21, the bent portion 21c of the cassette transport body 21 starts to come into contact with the engaging pin 19 projecting upward of the rear surface regulation member 17, whereby the rear surface regulation member 17 moves. Since the engaging pin 19 projecting downward starts to move from the V-shaped bent portion 11b _{1 of the} guide groove 11b to the straight portion 11b ₂ , the rear surface regulating member 17 removes the sliding pin 18 and the engaging pin 19 projecting downward. Starting to rotate in a very slight clockwise direction (arrow direction) toward the center, the regulating portion 17a reaches the vicinity of the corner portion of the cassette 2.

FIG. 8 shows a state in which the cassette carrier 21 and the cassette 2 are further moved in the direction of arrow B ₁ from the state of FIG. In the state of FIG. 8, since the engaging pin 19 projecting downward of the rear surface regulating member 17 has completely moved to the straight portion 11b ₂ of the guide groove 11b, the rear surface regulating member 17a is further rotated in the clockwise direction (arrow direction). To do. As a result, the regulation portion 17a comes into contact with the rear surface 2b of the cassette 2. Accordingly, the front and rear surfaces 2a and 2b of the cassette 2 are position-controlled between the restriction portion 13a of the front surface restriction member 13 and the restriction portion 17a of the rear surface restriction member 17, and the cassette carrier 21 and the cassette 2 are kept in this state for a while. When moving in the direction of arrow B ₁ , the state shown in FIG. 9 is reached.

In the state shown in FIG. 9, the sliding pin 14 of the front surface regulation member 13 is moved from a predetermined position while the cassette carrier 21 is moving, that is, before the cassette 2 is transferred to the cassette holder 51 (FIG. 5). Of (14a, 14b), the sliding pin 14a moves from the straight portion 11a ₁ of the guide groove 11a to the dogleg portion 11a ₂ . At this time, since the front surface regulation member 13 rotates in the clockwise direction (arrow direction) around the sliding pin 14 (14a, 14b), the regulation portion 13a of the front surface regulation member 13 does not come into contact with the front surface 2a of the cassette 2. The restriction portion 13a is released to avoid the side surface 2d side of the cassette 2.

After that, when the cassette carrier 21 and the cassette 2 are moved in the direction of the arrow B ₁ , the state shown in FIG. 10 is reached. In FIG. 10, since the position regulation of the front surface 2a of the cassette 2 is released, the rear surface 2b is arrowed by the regulating portion 17a that cooperates with the movement of the cassette transport body 21 to regulate the rear surface 2b of the cassette 2. B It is pushed in the ₁ direction. Further, in this state, even if the cassette carrier 21 is moved in the direction of the arrow B ₁ , since the restriction portion 13a of the front surface restriction member 13 is avoided, there is no transmission member for moving the front surface restriction member 13, and the front surface restriction member 13 is not provided. Reference numeral 13 keeps the position where the sliding pin 14 (14a, 14b) is still fitted in the dogleg-shaped bent portion 11a ₂ by the urging force of the spring 16.

[0053]   Then, the cassette carrier 21 and the cassette 2 are moved to the position shown in FIG. ₁ When the cassette 2 is moved in the direction Reach the place. At this time, a cassette moving mechanism (not shown) of the cassette holder 51 operates to operate the cassette. 2 is mounted on the cassette holder 51.

[0054]   Next, the cassette 2 mounted on the cassette holder 51 is attached to the cassette carrier 21. The returning operation is the reverse of the above. Here, explanation is given during the reverse operation. Only describe matters that have not been done.

At the time of this returning, the operation of returning the sliding pin 14 (14a, 14b) of the front surface regulation member 13 from the bent portion 11a ₂ to the straight portion 11a ₁ is performed by the cassette carrier 21 in the direction of arrow B _1. As the folded portion 21d of the cassette carrier 21 abuts on the engaging pin 15 of the front surface regulation member 13 as it moves in the opposite direction, the front surface regulation member 13 may move in the direction opposite to the arrow B ₁ direction. it can. Further, when the cassette carrier 21 and the cassette 2 are returned to the states of FIGS. 7 and 6, the position regulation of the rear surface 2b of the cassette 2 by the regulation portion 17a of the rear surface regulation member 17 is released, so that the front surface 2a of the cassette 2 is removed. Since the front surface 2a is pushed in the cassette insertion direction by the restricting portion 13a of the front surface restricting member 13 whose position is restricted, the cassette 2 can be manually detached from the cassette carrier 21 thereafter.

[0056]   As described in detail above, according to the cassette autochanger device 1 of the present invention. Then, the members constituting the cassette carrying mechanism 10 in the magazine 5 are made of rubber or the like. Since it can be configured without using a wear member, many operations of the cassette carrying mechanism 10 It can withstand repeated operations, improving the reliability of the cassette transport mechanism 10. The cassette 2 stored in the cassette carrier 21 in the magazine 5 Practical advantage that can be reliably transferred to and from the cassette holder 51 in the performance unit 50 Cause In addition, the cassette 2 can be attached / detached on the front side of the autochanger device 1, The advantage that the magazine 2 can be easily made from the front surface 2a side can also be accompanied.

[0057]   In the cassette transport mechanism 30 having the above structure, the front surface regulation member 13 and the rear surface regulation member 13 The control member 17 slides on the partition plate 11 in cooperation with the movement of the cassette carrier 21. However, the structure is not limited to this and can be configured as shown below. is there. That is, the cassette carrier 2 that moves the front surface regulation member 13 and the rear surface regulation member 17 One pair is supported on each of the left and right sides of 1, for example, a magazine 5 or a partition plate. 11 are provided with respective cam-shaped guide portions, so that the cassette carrier 21 can be moved to a predetermined position during movement. From the position of the front side regulating member 13a and the rear side regulating member by the cam-shaped guide portion. The restriction portion 17a of the control member 17 is configured to contact and separate from the front and rear surfaces 2a and 2b of the cassette 2. May be. Furthermore, do not provide a pair of the front surface regulation member 13 and the rear surface regulation member 17, respectively. In addition, one is provided in each of the central portions, and the cassettes 2 are arranged in the vertical direction of the front and rear surfaces 2a and 2b. It may be configured to appear and disappear freely.

[0058]   Therefore, in the present invention, the regulation portion 13a of the front regulation member 13 of the cassette transport mechanism 30 is used. Also, the regulation portion 17a of the rear surface regulation member 17 cooperates with the movement of the cassette carrier 21. It is a technical idea to have a structure in which the front and rear surfaces 2a and 2b of the cassette 2 are brought into contact with and separated from a fixed position. It is an idea.
