Abstract

PURPOSE: To ensuare an instantaneous switching between the winding and the quick winding through a simple constitution and without giving any abnormal tension to the tape, by giving a fixed selective switching to the rewinding and quick winding modes in accordance with the operation and via a logic process.
CONSTITUTION: When the rewinding switch SW1 is turned off, the low-level pulse having a duration which is decided by the resistance R2 and the capacitor C1 is delivered from the NAND circuit NAND1. And thus the FF2 and 1 are reset and set each, and the rewinding mode is secured instantaneously regardless of the mode of the quick winding switch SW2. In the same way, the switch SW2 is closed to secure immediately the quick winding mode regardless of the state of the switch SW1. Accordingly, if one of the quick winding and rewinding modes is operated in the other mode, an instantaneous switching is secured to the other mode. And with cancel of the mode, an automatic and instantaneous switching is given to one mode. And a simultaneous driving is not given to the both quick winding and rewinding motors to prevent the abnormal tension of the tape. Thus the head leading of the tape can be secured in a good condition.
