<p>PROBLEM TO BE SOLVED: To load a sheet material smoothly, easily, and surely when the sheet material is loaded on a middle plate. SOLUTION: When a sheet S is loaded on a middle plate 3, pressing force, due to a side press spring 22 provided on a picture image forming device main body 11 side, is not worked to a side press plate 18, thereby the sheet S can be smoothly loaded. When a cassette, on which the sheet S is loaded on the middle plate 3, is housed in the housing part 12 of the main body 11, a solenoid 23 is turned off by a signal from a control device 24 to release the holding a pressing bar 21, thereby making the press plate 18, pushed by he pressing bar 21 and the pressing bar receiving part 20 by the spring force of the side press spring 22, pressurize the sheet S, to push the sheet S to a sheet end part regulating plate 16 to be adopted as a paper reference surface.</p> |
