Abstract
PURPOSE: To enable to take a high velocity ratio between operations of high speed and low speed and stabilize the sheet-feeding in a captioned device by short-circuiting both ends of a supply-side motor at the low-speed operation of a winding-side motor and opening the both ends of the supply-side motor at the high speed operation.
CONSTITUTION: When a film is fed to a take-up reel 13 from a supply reel 8 at a low speed, a switch S3 to its contact (a) and a switch S4 to its contact (a) are respectively connected for setting a circuit of a motor M2. Meanwhile, a switch S1 to its contact (b) and a switch S2 to its contact (b) are respectively connected for short-circuiting both ends of a motor M1. Then, when the film is fed in the same direction at a high speed, the switch S2 is connected to its contact (b) for opening both ends of the motor M1. In this construction, on the basis of the switching of switches, braking is given at a low-speed operation and restrained at a high-speed operation for expanding the variable range of the speed.
