Claims

[Scope of utility model registration request]

A rotating shaft rotatably incorporated into a bearing tube formed in the frame, a worm that drives a number wheel provided at one end of this rotating shaft, and a worm attached to the other end of the rotating shaft to receive rotation transmission from a drive source. In a counter comprising a pulley and a worm wheel that meshes with the worm, a first clutch means is disposed between the pulley and the rotating shaft, and the worm wheel is moved onto the spindle via the second clutch means. The first clutch means operates to connect the pulley and the rotation shaft when an addition rotation input is transmitted from the drive source, and to disconnect the pulley and the rotation shaft when a subtraction rotation input is transmitted, and the second The clutch means allows the worm wheel to rotate when the additional rotational input is transmitted, but
A counter that operates to prevent rotation when a rotational force in a subtraction direction is applied.
