Abstract

PURPOSE: To confirm the number of the remaining forms easily by mounting a plurality of light controlling sections to a moving body interlocked with a form base and changing the controlling sections by stages in response to the quantity of movement in the detector for the number of the forms housed in a cassette for a copying machine.
CONSTITUTION: A reflecting plate unit 18 is fitted to a nose section of the detecting lever 16 interlocked with the form base 12, and the light reflecting sections 201W 204 as the light controlling sections are mounted onto the surface of the rectanglar light absorbing plate 19. The reflecting sections are shaped rectangularly in the same width dimensions W, and each have different length dimensions. On the other hand, light transmitting and receiving sections 231W234 formed by pairing fiber glasses 214W214 for transmitting light and fiber glasses 221W224 for receiving light are arranged oppositely to the reflecting sections 201W204, and a rise of the reflecting unit 18 due to the decrease of the number of the forms 13 is detected by stages by means of phototransistors 271W274. Accordingly, the number of the forms can be detected accurately by determining the length of the reflecting sections corresponding to the number of the remaining forms.
