<p>PURPOSE:To contrive the correctness of positioning even in the time of an error in size and a change of humidity by providing a member urged by a paper guide engaging with a cassette bottom part further a stopper means in which the cassette bottom part adjusts a guide position of the engaging member in its point end in two or more positions. CONSTITUTION:When a lever 31 of an engaging member 28 is pressed and turned against urging force of a spring 27 in the counterclockwise direction in the time of storing paper, an engaging bar 33 is lifted retracting from a bottom part 34. Next moving a paper guide 23 to a position suited for size of the stored paper, when the lever 31 is released from being pressed, the lever 31 turns in the clockwise direction by the urging force of the spring 27, and the engaging bar 33 lowers engaging with a recessed part 29 corresponding to the size of the paper. Thus, the paper guide 23 is positioned in a width direction of the paper. Here, a clearance between the guide 23 and the side end of the storage paper can be formed to within 1.5mm when a space of the recessed part 29 is set to 1.5mm, even when unevenness is provided in the size of the paper due to its cutting error and a change of humidity or the like, the paper guide 23 displaces its position from the ideal position only by 1.5mm even in the worst case.</p> |
