ないことになる。Furthermore, since there is no need for the blind M4 to cover the notch 3a of the table 3 that was opened in order for the paper guide 1 to move, the number of parts can be reduced, and it is also necessary to adjust the amount of deflection of the leaf spring 2. Since there is no need to do this, significant cost reductions can be achieved. Furthermore, each time the size of paper to be loaded on the table 3 is changed, the bottom plate 8 must be prepared according to the size of the paper. From the standpoint of operability and workability, it is rare to change the paper size for one paper feed hopper, so there is little need to prepare a plurality of bottom plates 8.
