However, the cassettes can be transferred smoothly between the cassette transfer machine and each cassette storage shelf.

[Prior Art] As a conventional example of a cassette autochanger using a video cassette, the applicant of the present invention has proposed, for example, Utility Model Application No. 1986-
The application described in the specification and drawings of No. 52569 was previously filed.

This conventional example is equipped with a large number of cassette storage shelves storing a large number of cassettes, a cassette transfer machine, and a recording re-export device, and selectively automatically transfers cassettes between the cassette storage shelves and the recording re-export device. This is a cassette autochanger configured to perform exchange using a cassette transfer machine.

In this type of cassette autochanger, each cassette storage shelf is usually
A reflective type detecting section 6 having a square hole 2 etc. is attached to the lateral side of the end 1a on the side of the cassette transfer device 4, and attached to the lateral side of the side surface 42 of the cassette transfer device 4 on the side of the cassette storage shelf 1. Each cassette storage shelf 1 is detected by a method such as detecting the center O of the square hole 2 of the detected part 3 using a sensor 5 such as an optical sensor.
The configuration is such that the cassette transfer machine 4 is positioned with respect to Y.

After positioning the cassette transfer machine 4 with respect to each cassette storage shelf 1, the cassette 6 is moved between the cassette entry/exit lower of the cassette transfer machine 4 and each cassette storage shelf 1.

Conventionally, as shown in FIG. 6, an inner wall 9a of a pair of five stones guides a pair of left and right cassette height reference surfaces 8a, sb on each cassette storage shelf 1, and guides both left and right sides 6a, 6b of the cassette 6. , 9b. A recess 10 is provided between the pair of five-stone cassette height reference surfaces 8a and 8b, and the bottom surface 6c of the cassette 6 is sent out from the inside of the cassette transfer machine 4 onto each cassette storage shelf 1 in the direction of arrow Ja, for example. The left and right ends of the E stone pair of cassette height reference planes 8
It was configured so that it was placed on the tops of the panels a and 8b.

[Problems that the invention is supposed to solve]

By the way, as shown in FIG. 8, the positioning reference when positioning the cassette transfer device 4 with respect to each cassette storage shelf 1 using the sensor 5 is based on the end portion 1a of each cassette storage shelf 1.
This is the center O of the square hole 2 of the detected part 3 provided on the lateral side of.

Therefore, as shown in FIG. 8, even if each cassette storage shelf 1 and the cassette transfer machine 4 are tilted relative to each other due to variations in assembly accuracy or wobbling due to operating conditions, the positioning reference O determined by the sensor will change. This does not occur, and the mutual inclination of each cassette storage shelf 1 and cassette transfer machine 4 is in the direction of arrow C with respect to the positioning reference 0 determined by the sensor.

For this purpose, conventionally, as shown in FIG. An overlap r)H in the vertical direction may occur between the farthest cassette height reference plane 8a and the end 6C of the bottom surface 6c of the cassette 6 on one side surface 6a side.

As a result, when trying to send the cassette 6 from the cassette transfer device 4 onto each cassette storage shelf 1 in the direction of the arrow a in FIG. End surface 8a on the side of the cassette transfer machine 4 shown in FIG.
There was a problem in that an accident occurred in which the cassettes 6 could not be delivered from the cassette transfer device 4 onto the respective cassette storage shelves 1 in the direction of the arrow a.

In order to eliminate this accident, it is necessary to correct the mutual inclination between each cassette storage shelf and the cassette transfer machine as described above, but the cassette autochanger has many cassette storage shelves 1 stacked up. Therefore, there is a problem in that the above-mentioned tilt correction work is a difficult work that requires a large amount of time and labor.

The present invention provides a cassette autochanger that allows cassettes to be smoothly received and transferred between the cassette transfer machine and each cassette storage shelf even if the cassette storage shelves and the cassette transfer machine are tilted relative to each other. is intended to provide.

[Means for Solving the Problems] In order to achieve the above object, the cassette autochanger of the present invention detects the detected portion provided on each cassette storage shelf, and connects the cassette transfer machine to each cassette storage shelf. a sensor for positioning the cassette storage shelf, a cassette height reference surface disposed at a position close to the detected portion of each of the cassette storage shelves, and a cassette height reference plane disposed at a position far from the detected portion of each of the cassette storage shelves; The cassette height reference plane is provided with a recessed portion cut downward relative to the cassette height reference plane.

[For production]

In the cassette autochanger configured as described above, the cassette height reference plane of each cassette storage shelf is arranged closer to the detected part of the sensor, which is the positioning reference of the cassette transfer machine with respect to each cassette storage shelf. Ori,
Moreover, since the recess cut out downward from the cassette height reference plane is located far from the detected part, each cassette storage shelf and the cassette transfer machine are the positioning standards for the sensor to be detected. Even if the cassette height reference plane is close to the detected part, it will not be affected by the above-mentioned inclination.Also, the farthest position from the detected part is a recessed part. Since the cassette height reference surface is cut out, when the cassette receiver is transferred between the cassette transfer machine and each cassette storage shelf, the recessed part furthest from the detected part is located at the eighth position. Unlike the prior art explained in the drawings, there is no problem such as the cassette colliding with the end face of the cassette height reference plane on the side of the cassette transfer machine.

Therefore, even if each cassette storage shelf and each cassette transfer machine are tilted relative to each other, cassettes can be received and transferred smoothly between the cassette transfer machine and each cassette storage shelf.
