This cushioning material 3 It goes without saying that the corresponding portion of the suction hole 2d is open.

[0008]   A suction tube 4 leading to the internal cavity 2e is connected to the camera fixing base 2 to be inspected, The internal cavity 2e of the camera fixing base 2 to be inspected is decompressed by a compressor not shown. It is like this. A pressure sensor 5 and a solenoid valve 6 are provided in the middle of the suction pipe 4. And a controller 7 for operating the solenoid valve 6 in conjunction with the pressure sensor 5 is provided. It is equipped. This controller is in a ready state on display means (not shown). And READY display signal to display and In addition to outputting the NG signal to be shown, the camera inspection device (not shown) Output a set completion signal indicating that fixing of the A test completion signal indicating that the inspection of the camera is completed is input.

[0009]   The camera 1 to be inspected is mounted on the upper surface portion 2c of the fixed base 2 of the camera to be inspected. The one side surface portion and the rear surface portion are respectively brought into contact with the fixed base side surface receiving portion 2a and the rear surface receiving portion 2b. Then, the suction force from the plurality of suction holes 2d causes the contact with the fixed base 2 of the camera 1 to be inspected. The touch portion, that is, the bottom portion of the camera 1 to be inspected in this embodiment, one side surface lower portion and the back surface lower portion The direction is adsorbed at a predetermined pressure. In this case, in the contact part of the fixed base 2 with the camera 1 to be inspected Since the cushioning material 3 is attached, the camera 1 to be inspected is not damaged.

[0010]   FIG. 3 shows a graph of measured values by the pressure sensor 5. The horizontal axis is time Yes, at time 0, the camera to be inspected 1 is placed on the fixed base 2 and the operator starts the compressor. It is when the power switch is turned on. The set pressure Pc of the compressor is determined by the camera to be inspected. The pressure is sufficient to fix the camera, but not enough to damage the camera under test. Needless to say.

[0011]   When the camera 1 to be inspected is correctly placed on the fixed base 2, all the suction holes 2d are inspected. Since it is blocked by the camera 1, the pressure P detected by the pressure sensor is shown in FIG. As described above, it stabilizes at a certain time Tc. However, the position where the camera to be inspected 1 is placed is not If so, a part of the suction hole 2d is opened without being blocked by the camera 1 to be inspected, so that the pressure P is It will be lower than when the camera 1 to be inspected is in the correct position.
