According to the twelfth aspect of the present invention, the rotating force of the rotating ring is applied to the rotating ring and the disk connected to the image pickup means by the attraction force of the magnets of different polarities. The direction of the image pickup means can be easily changed to an arbitrary direction with a small force and transmitted to the image pickup means.

According to the thirteenth aspect of the present invention, the image pickup means is mounted at an arbitrary position on the tape by inserting the connector having the image pickup means into the tape in which the electric wiring such as the signal line is embedded. Can be. Further, since the image pickup means can be installed only by inserting the connector into the tape, the mounting operation is simple and the operation time can be reduced.
