Abstract
Abstract The invention provides a conversation device having a space key for instructing feeding of a printing tape without printing, a pulse oscillator for producing pulses of predetermined period upon depression of the space key, a counter for counting the pulses generated from the pulse oscillator, a one-shot multivibrator for producing a pulse to indicate that the count value has reached a predetermined value, a flip-flop which is set by the pulse from the one-shot multivibrator and allows the pulses from the pulse oscillator to be supplied to a motor driver for amplifying the pulses and which is reset when the predetermined number of pulses from the pulse oscillator is received and prohibits the supply of the pulse oscillator to the motor driver, and a pulse motor for feeding the printing tape without printing. Therefore, when the flip-flop is set, the motor driver causes the pulse motor to drive the printing tape for a predetermined length corresponding to a plurality of characters. The device further includes a CPU for discriminating a depressed key and for supplying a signal to the motor driver which causes the pulse motor to drive the printing tape for a length corresponding to one character.
