Abstract
A Centronics type interface comprising a switching circuit selectively outputting one of two input signals having a timing relationship such that only during the time one input signal is active, the other input signal is active according to the state of a select signal, a pulse generating circuit outputting a signal for a predetermined time from the rising edge of a signal outputted from the switching circuit, and a signal selecting circuit outputting one of the other input signals and a signal outputted from the pulse generating circuit, which can hold one input signal and the signal outputted from the signal selecting circuit in a desired timing relationship.
