Claims

[Scope of utility model registration request]

A character wheel having a plurality of digit wheels coaxially provided, a step motor having a rotor provided on an axis common to the central axis of the character wheel, and a step motor that decelerates the rotation of the step motor to reduce the rotation of the character wheel to the lowest position of the character wheel. It consists of a speed reducer that transmits information to the digit wheel, and an electronic circuit that operates when a power supply voltage is applied to drive the step motor, so that the power supply voltage continues to be applied to the writing electronic circuit during the operating time. An operating time meter characterized by:゛・
