Abstract: A tape counter with the structure where a substantially U-shaped frame is provided with digit wheel engaging grooves vertically notched on both side plates thereof, a digit wheel shaft axially mounting digit wheels is fitted on both ends to said engaging grooves, a lens member is integrally formed on a cover assembled over the frame to magnify and display digits on the digit wheels, positioning projections are integrally formed on the internal surface of the cover on the center line of the lens member, the reading line of the digit wheels is aligned with the center line of the lens member by engaging the projections into the digit wheel shaft engaging grooves, a side play adjusting spring having a slit extending upward from the lower end thereof to allow the digit wheel shaft to pass therethrough is inserted between the side plates and the highest order digit wheel and the upper end of the side play adjusting spring is caught with the internal surface of the cover.

Abstract: A reset mechanism for an odometer is provided. The reset mechanism operates by means of manually rotatable structure which causes rotation of a reset shaft provided in an odometer. Means are provided for permitting manual rotation of the odometer reset shaft through an angular distance of more than 360.degree. before a stop structure is encountered. Spring means are provided to urge the reset mechanism to a start position after each resetting of an odometer. The reset mechanism requires only about half as much manual rotation as the necessary reset rotation for the convenience and ease of the operator.

Abstract: A counter comprising a U-shaped frame, a plurality of digit wheels each having a heart-shaped cam, pinions respectively located between adjacent digit wheels for shifting the digit, a zero resetting bracket which supports the pinions and including a plurality of press members for pressing the heart-shaped cams, a reset button for operating the zero resetting bracket to disengage the digit wheels from the pinions and to press the heart-shaped cams with the press members thereby resetting the digit wheels to zero and drive means for driving the digit wheel. A plurality of slots are provided in the frame at positions beneath respective digit wheels for receiving respective heart-shaped cam push members. A cover including a magnifying lens for reading the numerical data displayed by the digit wheels is mounted on the frame to cover the digit wheels. The reset button is supported by the cover.

Abstract: A resettable mechanical counter having a plurality of number wheels and transfer pinions is mounted in a molded plastic housing in which are integrally formed fixed bosses that index the transfer pinions when the number wheels are reset. The transfer pinions are axially located by means of slots formed in the housing and the number wheels are axially located relative to the reset lever mechanism which itself is axially located relative to the housing to thus position the transfer pinions relative to the number wheels.
