Abstract

PURPOSE: To obtain an appropriate output image by performing reduction from size B4 to size A4 in both main and sub-scanning when the main scanning width of a receiving/reading original is equivalent to size B4 and the size of the recording paper is of A4 and further performing automatic or fixed reduction when the length of the sub scanning exceeds that of the recording paper of A4, etc. CONSTITUTION: An original is read by a contact sensor CS 9, and encoded via a read control gate array 10, and stored in image memory 13. A stored image is decoded by a recording control gate array 11, and reduction-processed by a reduction processing IC, and print-outputted on the recording paper by a laser printer 12. Also, received image data is demodulated by a modem 4, and checked whether or not an image error exists, and stored in a DRAM 13. The stored image is reduction-processed 14 by the content of an SRAM 3 after decoding, and outputted on the recording paper by the laser printer 12. At this time, reduction from B4 to A4 in both the main and sub-scanning is executed when the main scanning width of the original is of B4 and the size of the recording paper is of A4, and further automatic or fixed reduction is performed when the length of the sub-scanning exceeds that of the recording paper of A4.
