The restriction body 4 cannot be pulled out with respect to the storage box body 3 in the vertical direction. Then, as shown in FIGS. 2 to 4, a pair of separation grooves 26, 26 are provided in the edge piece 2 in the longitudinal middle portion of at least one of the left and right guide grooves 22.
By drilling from 1 to the second bottom piece 15 so as to extend in a direction intersecting with the extending direction of the guide groove 22 in a plan view, the base end of the second bottom piece 15 is formed between the pair of separation grooves 26, 26. A series of elastic locking pieces 27 is formed. In this case, the tip portion (free end portion) 27 a of the elastic locking piece 27 is bent downward so as to be located at the height of the guide groove 22. The front-rear width dimension of the tip portion 27a of the elastic locking piece 27 is L1.

When the tip end portion 27a is bent downward by pushing the tip end with the finger, the tip end portion 27a is configured to sink into the through hole 28. On the other hand, of the edge portions 25, 25 on the left and right sides of the restricting body 4, the elastic locking piece 2
An engaging groove for fixing the position of the regulation body 4 with respect to the storage box body 3 in the front-rear direction according to the size of the paper 11 in the front-rear direction is fixed to the edge portion 25 corresponding to the side where the sheet 7 is provided. 29 are provided at a plurality of locations (two locations in the embodiment). The front-rear length dimension L2 of each engagement groove 29 is formed slightly larger than the front-rear dimension L1 of the tip portion 27a.

When the lower end 24 of the front end is brought into contact with the downward edge of the front end 24, the restricting body 4 cannot be inadvertently removed rearward.
Next, the operation of assembling and adjusting the position of the paper feed cassette thus configured will be described. As shown in FIG. 3, from the open rear end side of the storage box body 3, the left and right side edge portions 25, 25 of the longitudinal direction of the regulation body 4 are arrowed with respect to the U-shaped left and right side guide grooves 22, 22. Insert in the A direction.

せれば良いのである。At the stage where the front end of the one edge portion 25 of the regulating body 4 collides with the tip end portion 27a of the elastic locking piece 27, as shown in FIG.
When 7 is pushed downward, its tip portion 27a goes into the through hole 28 and the edge portion 25 can be inserted in the front guide groove 22 direction. Then, while the downward pressing force on the elastic locking piece 27 is released, the restricting body 4 is slid in either of the front and rear directions, and the engaging groove 29 in the restricting body 4 and the tip of the elastic locking piece 27. At the position where the front and rear positions of the portion 27a coincide with each other, the tip portion 27a returns upward so as to fit into the engagement groove 29 (see FIG. 6), and the tip portion 27a is moved to the guide groove 22.
Since it is held so as to be substantially the same height as the edge portion 25 within the height of, the restricting body 4 cannot move back and forth at that position. When the sheet 11 having a short front-rear length is used, the engaging groove 2 on the side closer to the vertical piece 23 (rear side) of the regulating body 4 is used.
It suffices to fit the distal end portion 27a of the elastic locking piece 27 to the shaft 9.

に移動できなくなるのである。Further, engaging grooves 34 are formed at a plurality of locations (only one location is shown in FIG. 8) corresponding to the front and rear sizes of the sheet 11 in the longitudinal middle portion of the edge piece 21.
The front-rear length dimension L2 of each engagement groove 34 is the same as the tip portion 33.
It is formed slightly larger than the front-rear dimension L1 of a. According to this configuration, when the elastic locking piece 33 is pushed downward by the operator's finger, the tip portion 33 a of the elastic locking piece 33 is positioned below the edge piece 21 and below the edge portion 2.
The regulating body 4 is movable back and forth as it approaches the upper surface of the regulating member 5. When the tip portion 33a of the elastic locking piece 33 of the regulating body 4 and the engagement groove 34 of the edge piece 21 are aligned, the tip portion 33a returns upward so as to fit into the engagement groove 34, The restriction body 4 cannot move back and forth at that position.
