ABSTRACT:
In a counter reset to zero by a push button and adapted to be mounted on a tape recorder or the like, there are provided a U shaped frame including a bottom plate, a pair of side plates, a spacer parallel with the side plates, a plurality of pinion aligning resilient members secured to the bottom plate, a digit wheel shaft supported by the side plates, a plurality of digit wheels rotatably mounted on the digit wheel shaft, and a driving gear rotatably mounted on the digit wheel shaft for driving a digit wheel of the lower most order. Each digit wheel comprises a heart shaped cam and a gear on one side and a carry pin gear on the other side. A zero resetting bracket is pivotally mounted on the frame and is provided with actuating members for actuating the heart shaped cams. The digit wheels are rotated by the source of drive of the tape recorder through the driving gear and each time a digit wheel of the lower order completes one revolution, a digit wheel of the higher order is rotated by one digit. A push button is mounted on either one of the side plates for simultaneously resetting to zero all digit wheels. In a modification a contact mechanism is provided for producing an electric signal which stops the operation of the tape recorder when the display of a digit wheel of the highest order changes from 9 to 0.
