PURPOSE:To prevent a malfunction of an operating knob, by turning a zero resetting turning body by moving a pulley on a knob shaft in the axial direction, turning a zero resetting member by intelocking with said turning, and resetting each figure wheel to zero and putting in order. CONSTITUTION:In case of resetting an integration meter to zero, when a knob shaft 12 is pushed to the small diameter direction from the large diameter side of a conically inclined surface 11a of a pulley 11, a press-contact part of an end part 13a in the diametral direction of an idle gear 13a and the inclined surface 11a moves to the large diameter side from the small diameter side of the inclined surface 11a to rotate the gear 13, and the rotation is transferred to a gear part 16a through a gear part 13a to rotate a drive gear 16. When a shaft 8 fixed to the gear 16 is rotated, an intermediate gear 4 held by a support plate 6 fixed to the shaft 8 is released from the figure wheel, and cam levers 6a-6d provided on the plate 6 are made to press-contact with a heart cam provided on the side of each figure wheel 2a-2d to reset to zero and put in order these figure wheels 2a-2d. |
