Abstract
PURPOSE: To offer a comfortable operation of an electronic typewriter which is controlled electronically, by conducting the repetition of various functional operations carried out in a repeat mode, according to signals each having a different frequency.
CONSTITUTION: A character key, a line feeder 1a, a space key 1b or a correction key 1d on a key board 1 is operated, and then a repeat key 1c is operated, so that a predetermined functional operation is repeated by an electronic control circuit 2. In this case, a signal obtained by the successive frequency division of a signal outputted from an oscillator 9 by flip-flops 10, 11, 12 is used as a repeat frequency signal to conduct each operation. A repeat space is set at a frequency level lower than that of a repeated typewriting operation, and the repeat of the line feeder is set at a further lower frequency level, so as to improve the operability. The repeat can be also done automatically by the continuation of the pushing-down state of the same key without use of the repeat key.
