PURPOSE:To enable the feeding of a layout which is too large to be fed into a paper feeder or the like by one rotation of a paper feed roller by rotating the paper feed roller two or more times using a mechanical paper feed trigger mechanism in a cassette feeder for the paper feeder. CONSTITUTION:When a paper feed command is issued from a controller, a motor 23 in a cassette feeder rotates to make a paper feed roller 22 mounted on a paper feed shaft 21 start rotating with the paper feed shaft 21. Here, when the paper feed roller 22 starts rotating for feeding paper, a trigger action is performed. Namely, a paper feed trigger for rotating the paper feed roller 22 twice is engaged by rotating a control ring 253 reverse (a predetermined pulse number) forward (a predetermined pulse number) reverse (a predetermined pulse number). The forward rotation of the control ring 253 from here results in the control ring 253 rotating twice to return to an initial position. At this time, the paper feed roller 22 rotates twice in synchronism with the control ring 253, and a paper feed action is completed. |
