Facsimile equipment and its head

Abstract

Abstract PURPOSE: To form a read head and recording head on one substrate in one body by reducing the number of circuit elements by providing only one driving circuit for driving both the heads in transmission and reception in common. CONSTITUTION: Read head part 1 having element 1a for one line and recording head part 2 having recording element 2a for one line are fixed on common wiring substrate 3 in one body and substrate 3 is provided with driving circuit connecting terminals 4 and 5 and amplifying circuit connecting terminal 6. To read facsimile information, original YA is irradiated with light L and its reflected light is caused to strike the read element by way of condenser lens CL. To record the information, the recording element is driven by the output of the driving circuit. Both the read and recording elements are divided into M groups of N sections and the groups are successively selected according to a clock signal inputted to counter 15 to output N picture signals from amplifying circuit 13 sequentially in parallel, so that one-line picture information will be read. In reception, picture signals are supplied to element 2a of the selected groups and then recorded. COPYRIGHT: (C)1981,JPO&Japio
