TW588545B - Sheet-size detecting mechanism - Google Patents

Abstract

A sheet-size detecting mechanism includes a sheet holder composed of a paper tray and a paper guide. The mechanism also includes a logic board and a sensor module. Adjusting the width of the paper guide corresponding to the sheet width may cause a lot of digital information to be generated due to relative motion between the logic board and the sensor module. Then, the sheet-size may be determined accordingly.
