In this figure, 10 is a supply conveyor that moves to the left, and 11 is a discharge conveyor that moves to the right. be. The test device 5 has a built-in recording and reproducing device 6.
This is to record magnetic signals on all tracks of the magnetic disk 3 of the disk cartridge A and then read and reproduce them to finally test the presence or absence of dropouts. The disk cartridges A are loaded one by one into the test device 5 and subjected to a performance test, and then discharged by the test device 5 and placed on a discharge conveyor 11 moving in the opposite direction to the supply conveyor 10. The process of supplying and discharging the disk cartridge A to the testing apparatus 5 will be explained in detail below with reference to FIGS. 5 to 7.

As shown in FIG. 5, the test device 5 has an intake port 12 at a side position facing the supply conveyor 10,
A take-in arm 13 is provided above the take-in port 12. This intake arm 13 is connected to the spring 1
A protruding piece 15 having a vertically extending bar 4 is fixed to its tip and near the center, and its rear end is connected to an electromagnetic plunger 17 via a crank rod 16.

When the disk cartridge A is placed on the supply conveyor 10 and conveyed to just below the take-in arm 13, the take-in arm 13 rotates clockwise around the tree 18 as a fulcrum due to the suction action of the electromagnetic plunger 17. A spring 14 abuts against the end of the disk cartridge A and the center hole, respectively.

A motor 19 is located near the inner side of the intake port 12.
A first drive belt 20 that can be rotated and conveyed by a first drive belt 20 and a guide member 21 having a tapered surface 21a are provided, and the rear end of the take-in arm 13 is connected to this drive belt 20. . Therefore, the disk cartridge A in contact with the spring 14 is moved into the testing apparatus 5 while sliding on the guide member 21 due to the movement of the take-in arm 13 as the motor 19 rotates. transported.

Inside the test device 5, a first shutter 22, a second shutter 23, and a third shutter 24 are installed.
They are arranged at appropriate intervals from the top. As shown in FIG. 7, the first shutter 22 consists of a pair of L-shaped rods 22a rotatable around a pin 25 and a movable rod 22b connected to these L-shaped rods 22a. The shutter 23 also has a pair of L-shaped rods 23a that can rotate around a pin 26, and these L-shaped rods 23a.
The third shutter 24 also consists of a pair of L-shaped rods 24a rotatable around a pin 27 and a movable rod 24b connected to these L-shaped rods 24a. . The center portions of the movable rods 22b, 23b, and 24b are fixed to the shafts of electromagnetic plungers 28, 29, and 30, respectively.

The disk cartridge A transported into the recording device 5 by the take-in arm is sent to the top of the first shutter 22 which is in the closed state, and is held there in a horizontal position in preparation for the next operation. When it is confirmed by a sensor (not shown) that there is no disk cartridge A in the second shutter 23, the electromagnetic plunger 28 is activated and the first
The shutter 22 is opened, and as a result, the disk cartridge A on the first shutter 22 falls horizontally under its own weight to the second shutter 23 position.
The shutter 23 receives the fallen disk cartridge A under its own weight and prepares for the next operation (see Fig. 7).

A transfer member 33 having an upper clamping plate 31 and a lower clamping member 32 is provided near the second shutter 23 and below the guide member 21 . This transfer member 33 is connected to a second drive belt 35 that can be rotated and conveyed by a motor 34, so that it can reciprocate in the horizontal direction. As shown in FIG. 6, the upper clamping plate 31 is fixed to the transfer member 33, and the lower clamping member 32 is rotatably supported by a shaft 36 installed on the transfer member 33, and is supported by a spring 37. It is elastically biased in the clockwise direction.

When it is confirmed that the recording/reproducing device 6 is ready for processing, the motor 34 is activated to move the transfer member 3
3 is moved to the left in FIG. When the transfer member 33 moves to the left, the lower clamping member 32 that was in contact with the lower surface of the guide member 21 is rotated clockwise by the spring 37 in order to separate from the guide member 21 . As a result of this operation, the disk cartridge A held in a horizontal position on the second shutter 23 is moved so that the vicinity of the opening 4 of the jacket 2 is connected to the upper holding plate 31 and the lower holding member, as shown in FIG. It is held between 32 and 32. When the transfer member 33 is further moved to the left, the disk cartridge A is fed into the recording/reproducing apparatus 6 while being held between the upper holding plate 31 and the lower holding member 32.

The recording/reproducing device 6 records magnetic signals on all tracks of the magnetic disk 3 of the supplied disk cartridge A, then reproduces and reads the signals, performs a final test for the presence or absence of dropouts, and determines whether the product is acceptable or not. . When the recording and reproducing device 6 finishes recording and reproducing the disk cartridge A, the motor 34 rotates in the reverse direction, and the transfer member 33
moves to the right in FIG. When the transfer member 33 moves to the right, the lower holding member 32 contacts the tapered surface 21a of the guide member 21 and rotates counterclockwise, so that the disk cartridge A
is released from being held by the upper holding plate 31 and the lower holding member 32, and is again held in a horizontal position on the second shutter 23 in preparation for the next operation.

Next, when it is confirmed that there is no disk cartridge A in the third shutter 24, the electromagnetic plunger 29 is activated and the second shutter 23 is opened.
As a result, the disk cartridge A on the second shutter 23 falls horizontally under its own weight and is received by the third shutter 24 in preparation for the next operation.
Then, when it is confirmed that there is no other disk cartridge A on the discharge conveyor 11, the disk cartridge A held by the third shutter 24 is moved to the third shutter 27 due to the operation of the electromagnetic plunger 30. When opened, the test device 5 is discharged horizontally from the discharge port 38 onto the discharge conveyor 11, placed on the discharge conveyor 11, and conveyed to the right in FIG.

Incidentally, in the above-mentioned embodiment, a case has been described in which the recording/reproducing device 6 is used for testing when manufacturing the disk cartridge A, but the present invention is not limited to the above-mentioned embodiment. For example, a magnetic code for retrieval is stored in advance at a predetermined position in the recording band of the magnetic disk 3, and such a disk cartridge A is supplied to and ejected from the recording/reproducing device 6.
The recording and reproducing device 6 can also be used for searching for a desired one among a large number of disk cartridges A.

As explained above, according to the present invention, the disk cartridges are sequentially dropped in a horizontal state to the shutters below, and the disk cartridges held by the second shutter are supplied to the recording/reproducing device. The disk cartridge is not damaged when it falls, and since three shutters are used to eject the supplied disk cartridge, the structure of the device can be simplified.
