Claims

[Scope of utility model registration request]

A support shaft and a zero return shaft are installed on both sides of the frame, and a plurality of number rings each having a heart cam on one side are inserted through the support shaft, and the zero return shaft is in contact with the heart cam. A substantially L-shaped zero return member is provided, which includes a zero return arm to obtain and a plurality of pinions for rotating the number wheel, and the number wheel is integrated and displayed through the pinion. In the totalizer, the zero return arm formed on the zero return member is brought into contact with the heart cam by the rotation of the zero return member, and each number ring is rotated to return, and one side wall of the frame is provided with the support. A cylindrical holder with a notched guide section along the axial direction of the shaft is fixed, and the holder accommodates the pressure knob via a return spring, as well as a pressure cam that protrudes laterally from the outer wall of the pressure knob. is arranged along the notched guide portion of the cylindrical holder, and a rotary cam that engages with the pressing cam is attached to one end of the zero return shaft. .
