Claims

[Scope of utility model registration request]

a plurality of number wheels each having a note cam; a plurality of carry pinions each interposed between these number wheels and transmitting the rotation of the lower digit number wheel to the higher digit number wheel;
a zero return member having a heart cam pressing piece that engages with the cam of each number wheel, and when pressed, temporarily separates the carry pinion from the number wheel and returns the number wheels to zero all at once; a reset prevention member that is coaxial with the number wheel and adjacent to the highest digit number wheel, has a heart cam and a zero return prevention protrusion on one side, and is biased in one direction by a spring; A member is provided corresponding to the zero return prevention protrusion, and maintains a non-coupling state with the zero return prevention protrusion during the first reset operation by the zero return member, allowing the heart cam pressing piece to press the heart cam; After the zero return operation is completed, the reset prevention member is brought into contact with the inner surface of the protrusion and moved in the axial direction against the spring, thereby disengaging the reset prevention member from the protrusion and returning the zero return member to its initial position. and an engaging protrusion that abuts the outer surface of the zero return prevention protrusion during subsequent reset operations to prevent the zero return operation, and the pinion shaft is moved in the direction of the number wheel by a spring. The spacing between the zero return preventing protrusion and the retaining protrusion is set to be smaller than the spacing between the pinion shaft and a pressing portion provided on the zero return member and pressing the shaft during a reset operation.
