Abstract

PURPOSE:To make width of cassette same as that of paper sheets having the maximum size by mounting a regulation plate which regulates the end of the sheets on the internal face of a side wall of a cassette case which stores the sheets having different size rotatably, and providing a knotched section which stores the regulation plate on the internal face of the side wall. CONSTITUTION:Internal width of a case 1 which stores paper sheets having different size is made equal to the width of the sheets having the maximum size. A knotched section 9 is formed on the internal face of a side wall 5 of it, and a regulation plate 6 is stored in this knotched section. It is on the same face as the side wall 5. At this time, a projection in the lower end of the regulation plate 6 engages with an engaging hole 10 of the case 1 and is stored in the knotched section 9. At the time of regulation, the regulation plate 6 is rotated and engages with an engaging hole 8 on the bottom. Also, the basic end of rotation of the regulating plate 6 is connected to the side wall 5 by a V-shaped groove 11 so that it can rotate. Therefore, it is unnecessary to make internal width of the case larger than the width of the sheets having the maximum size.
