本考案は回転デイスクから情報信号を読み取る
のに使用されるピツクアツプ送り装置の微少送
り、早送りに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to minute feed and rapid feed of a pick-up feed device used to read information signals from a rotating disk.

が限度であつた。 Conventionally, the minute feed and rapid feed devices for pick-up mounts have slowed down the rotation speed of the motor using gears, etc. to perform minute feeds. In this case, the maximum rotation speed of the motor for rapid traverse and return is limited, and the speed ratio of minute feed and rapid traverse is, for example, if the minimum rotation speed is 50 rpm and the maximum rotation speed is 2000 rpm, the speed change ratio of feed is 1:40. Therefore, the limit was several tens of times at most.
本考案は従来の送り速度比を飛躍的に向上させ

る。 This invention was devised to dramatically improve the conventional feed rate ratio and increase the feed rate by more than 1,000 times.
To explain the embodiment shown in the drawings, as shown in Fig. 1, it has two motors 1 and 2 with slightly different rotational speeds and opposite rotational directions, and the belt drive motor 1 rotates clockwise. , a belt 5 supported by a pulley 3 and a pulley 4 attached to the shaft of a drive motor 1 is driven. A motor 2 fixed to a pick-up mount 8 that moves along a slide shaft 9 rotates counterclockwise.
The roller 6 and pinch roller 7 attached to the shaft are attached so as to sandwich the belt 5, and the pinch roller 7
moves together with the pick-up mount 8 along the slide shaft 9, and the roller 6 is a pick-up moving device movably mounted on the belt 5.
本考案実施例は上記のような構造になつている

ーター２を停止させれば良い。 Since the embodiment of the present invention has the above structure, the motor 1 rotates and the belt 5 moves, but when the motor 2 is rotated so that the roller 6 rotates slightly faster than the speed of the belt 5, In FIG. 1, the pick-up mounting base 8 is slightly moved to the left. Also, when fast forwarding to the left, motor 1 may be stopped, and when returning to the right, motor 2 may be stopped.

ので工業上有効な考案である。 As mentioned above, this invention performs minute feeding by using the difference in the rotation speed of two motors. For example, if the rotation speed of motor 1 is 1000 rpm and the rotation speed of motor 2 is 1001 rpm, the speed ratio is 1:1000. is obtained. Further, if the rotational speed of the motor 2 is set to 1000.5 rpm, a speed ratio of 1:2000 can be obtained, and one motor is stopped to perform fast forwarding or return, which is an industrially effective idea.
