AUTO-DETECTING CONTROL DEVICE AND METHOD OF PAPER SIZE

摘要

According to the present invention, a separate size recognition lamp is installed in the image scanner, and the size recognition lamp scans the horizontal and vertical sizes of standard and non-standard originals placed on the contact glass, and digitally processes this signal, thereby eliminating the selection of copy paper. It relates to a document size automatic detection control device and a control method for automatically feeding and sorting according to the size, the size recognition lamp (3) mounted on one side of the image scanner (1); A charge coupled device 7 embedded in the image scanner 1; An analog / digital converter 12 connected to the charge coupling element 7; A stepping motor driver 13 mounted to one side of the first home position sensor 4; An image process central processing unit 11 mounted in the copier main body; And a control method applied to a document size automatic detection control device and a document size automatic detection control device having a central control unit 14 connected to the image processing central processing unit 11 to copy a standard or non-standard document. When copying a book or the like, scanning the light of the lamp to the size of the original does not affect the worker's eye fatigue even when copying without closing the platen, and also automatically selects and feeds copy paper so that it can be quickly replaced by originals. There is an effect that the copy operation can be performed.
