In step S _11, examines the normal or abnormal lock in the same manner as the previous step S _6, performs defect output of the disk device 7 if abnormally As before step S _12. When exiting abnormality in one of the drive, and the hand unit 12 proceeds to step S ₁₃ is the normal case in all drives is moved to the origin, the engaging portion 1
3 is separated from the knob 21. At this time, the control personal computer 6 rotates the conveyor 5 and carries the next DUT (disk 7 device) 7 into a predetermined position. Step Flow When the test is not completed in the S ₁₄ all the test object 7 is finished, all the process returns to step S ₁ If there is the test object 7 in the other repeats the above operation until the end.

Particularly, the movement of the hand portion 12 when the disk device 7 is a drive type will be described with reference to FIG. The engaging portion 13 moves to the front of the information knob 21 by the operation, the knob 21 is fitted into the recess 13a by the operation, and the no-lock test is performed by the operation. Next, in operation, disengage from the upper knob 21,
By operation, the lower knob 21 is moved to the front, and by operation, the knob 21 is fitted into the recess 13a, and a no-block test is performed by operation. Then, it moves away from the lower knob, and moves to the top.

When the other type of disk device in the bar code reader in Step S _3, for example, 3.5-inch floppy disk type with a knob of a push button type is read, the robot 3 is operated in accordance with the knob, the pusher of the cylinder 17 The lock test of the button type knob is performed by 14.

Thus, this device has a ROM 23 for knobs of different models.
It is possible to read the corresponding data from and respond immediately.

The pusher 14 can also be used for a keying test of a keyboard of a laptop computer. That is, one of the keys is tapped by the pusher 14, and it is tested whether or not the key input is reliably transmitted to the personal computer main body.
