Claims

[Scope of utility model registration request]

A photoconductor replacement timing notification device for a copying machine that uses a moving photoconductor having a circumference shorter than the length of the transfer paper in the conveying direction to copy an original image. , a pulse generating means for generating a pulse signal synchronized with the movement of the photoreceptor, a counting means for counting the pulses from the pulse generating means, and a notification that the count value of the counting means has reached a predetermined value. It has a notification device,
The photoconductor replacement time is automatically notified by the notification device by setting the predetermined count value to be notified to a value corresponding to the photoconductor replacement time. Notification device.
