<p>PURPOSE:To attain required three operations with simple constitution by applying fast feeding in a desired direction by the selective operation of two sets of moving members so as to select the tape running direction by the simultaneous operation. CONSTITUTION:Pin engagement is disengaged and a lever is turned by a spring force through power application to a coil of an electromagnetic machine, then a follower gear having missing teeth is turned, and meshes with a main gear and is turned once. Then the 1st moving member 8 is forwarded, the turning drive to a reel is switched to attain right direction fast feeding. In this case, a tape direction switching member 26 is turned clockwise via a pin 8a of a member 8 and not moved. Similarly, the left fast feeding is attained via the 2nd moving member 9 and the member 26 is not moved while being turned counter clockwise by a pressing section 25 of the member 9. On the other hand, in operating the members 8, 9 at the same time, the slope 28 responds to the pin 20 of the member 8, the member 26 is forwarded, a pressing delivery member 31 is shaken to switch the tape running direction. Thus, the fast feeding direction and tape running direction are switched with simple constitution not requiring lots of electromagnetic mechanisms.</p> |
