Abstract

PURPOSE:To display a rotary disk the extent of rotation that corresponds correctly to the extent of the movement of a body, by holding the length of a belt, transmitting the rotation of a movement-extent detection roller, constant by moving up and down the roller. CONSTITUTION:The driver of rotary disk 6 for timing pulse generation, when movement-extent detection roller 12 pressed against an original surface moves up and down according to fluctuations of the original surface, varies the opening angles of tension arms 22 and 23 according to the upward-downward motion of roller 12. To hold the tension of belt 30 constant all the time, namely, to hold the length of belt 30 constant, it operates. As a result, disk 6 rotates to show the extent of rotation that corresponds correctly to the extent of the movement of body 1 detected by roller 12. Further, even if roller 12 moves up and down, the extent of the press of roller 12 against original surface O has not large variance. Therefore, timing pulses are generated in an excellent state all the time.
