<p>PURPOSE:To make possible to confirm that blank form sheet are set correctly, and the weight due to a paper weight means is sure and always to perform normal image forming work, by providing a paper weight means and a paper detecting means in a paper tray. CONSTITUTION:Make a paper feeding board 7 descend, place a bundle of blank form sheets 3 on the paper feeding board 7, make a paper weight lever 2 move, line up the lower end of the blank form sheets 3 to a designated position, and make its right end touch on the left side face of the paper tray 1. Then, drive a motor 12, make the paper feeding board 7 rise together with the blank form sheet 3, and stop the motor when the blank form sheet 3 is detected by switch 16, and the setting of blank form sheets is completed. At this time, if the setting is sure, switches 4, 5, and 6 are all turned on, and paper feeding becomes possible. Furthermore, when the paper weight lever 2 weights a standard size blank form sheet at a designated position, an actuator is operated and make a corresponding reflecting type phone sensor 18 on, and sureness of the weight is indicated.</p> |
