PURPOSE:To enable the plural kinds of control sections to be used at the same time with a comparatively simple composition by converting serial data to parallel data on the side of a data sink section, to separate an output section connected to the side of an image processing main-body, from a converting section on signal processing timing, and by composing a state which is electrically equivalent to the data output state of the control sections. CONSTITUTION:By a data sink section 16, the various control data of output generated from first and second control sections 11, 12 are received via a data source section 15, and are read, and are reset in a state which is electrically equivalent to an operated state at the control sections. So far as serial signal S9 converted to electrical signal at a light receiving section 48 is concerned, an error is checked at a discriminating section 54, and when it is discriminated that the signal is significant signal, then the input of an only data section to a converting section 55 is provided, and serial data are converted to parallel data. When the data of provided input to the converting section 55 are defined, then the data are written in a housing section 56 and are retained as signal receiving data, and by the timer signal of output generated from a reference generating section 57 and by directing output to an output section 58 regularly in no relation to data receiving working due to the converting section 55, the output section 58 is separated from the data sink side on timing. |
