Abstract
PURPOSE:To execute quick and accurate diagnosis, by enabling to switch and input diagnostic signals to the input side of some functional blocks from a diagnostic signal generating circuit suitably. CONSTITUTION:In diagnosing a printer circuit 7, a selector switch S7 is switched, a test pattern signal of a diagnostic signal generating circuit 10 is supplied to a printer circuit 7, and the normality of the printer circuit 7 can be diagnosed from a playback output picture 9 obtained at that time. Further, the switch 7 is switched to a facsimile device, the test pattern signal is input to a demodulating circuit 5, and the diagnosis of the demodulation circuit 5 the same as mentioned above. Similarly, the normalities of a modulation circuit 3, memory circuit 2 and a video information read-in circuit 1 are diagnosed by the switching of switches S4-S6.
