Abstract

PURPOSE: To enable a controller of a tape reader for a numeric controller to attain effective control, by preventing a trouble caused by mechanical abrasion by eliminat ing a mechanical preload, by applying a pre-load electrically.
CONSTITUTION: This controller is provided with tape reader 1 reading information from tape 2, reel driving motor 6 winding and rewinding tape 2, and reel arm 4 operating according to the advance of tape 2. Then, the handler of a tape reader which performs the ON-OFF control of forward or reverse turning according to the position of reel arm 4 is also provided with amplifier 9 supplied with a voltage of either power supply +Vcc or -Vcc through the alternations of micro-switches 7 and 8, and power amplifier 10 in addition to the feedback loop which feeds the output voltage of amplifier 10 to the input side of amplifier 9. The voltage of motor 6 is made constant to prevent the hunting of the motor caused by the ON- OFF control.
