Abstract
Abstract A standard-length positioning apparatus wherein acceleration and deceleration of a driving mechanism for actuating a mechanism for feeding a material is controlled by a digital positioning mechanism according to a position feedback. Marks marked on the material are read by a sensor during the deceleration of the driving mechanism, and the digital positioning mechanism outputs a signal for stopping the driving mechanism when it receives the read-in output of the sensor while the driving mechanism is being decelerated. When a signal from the sensor is not received by the digital positioning means while the drive is being decelerated, the digital positioning mechanism utilizes feedback pulses of a positioning detector to stop the drive.
