Device for detecting travel condition of inkribbon for printers

摘要

A device for detecting a travel condition of an inkribbon for printers is disclosed. The device is composed of a rotary member rotatable in response to the travel of the inkribbon and a signal generation means interlocked with the rotary member. The signal generation means generates a detection signal and can not only detect trouble of the detection device but also detect a mode in operation of a carrier on which the detection device is arranged as well as detect the travel of the inkribbon.
