<p>PURPOSE:To attain the switching of the operation of an automatic answering telephone set, by providing several number of locking pieces on the front and the rear of a driving gear, changing an operating position at the locking position of the driving gear, and rotating the driving gear by a spring in one direction. CONSTITUTION:A responding endless tape cassette is contained in a cassette container room 15, and a recording tape cassette is loaded in a cassette container room 18 at the front of a second recording and reproducing head 9, then a waiting state is generated. At this time, a driving gear 30 intends to rotate in a clockwise direction by a pressing force of a spring 36, but the rotation of the driving gear 30 is blocked by the connection of the connecting end part 40 of a lock lever 41 to the connecting piece 46a of the driving gear 30. When a call state is generated by receiving a call signal, a plunger 37 is energized for several seconds, thereby, an attracting operation is performed, and the lock lever 41 is rotated in a counterclockwise direction, thereby, the engagement between the locking end part 40, and the locking piece 46a, is canceled, and the driving gear 30 is moved a little in the clockwise direction. In this way, the turning position of the driving gear can be controlled only by changing the driving time of the plunger, and a various kinds of operating states can be obtained, and especially the titled device is suitable for the automatic answering telephone set.</p> |
