In other words, in the paper feed section, the stack of sheets is placed in the initial standby position, and then After all the sheets have been fed out and the carrier plate is empty, wait until the operation is complete. Transport it to the machine position and move it to the operating position. Note that the empty cache The rear plate is attached to a lifting table (keyboard) that rises as the number of sheets increases during operation (decrease in stacked sheets). carrier plate) and is sent back to the initial standby position to receive the next stacked sheet. Waiting for acceptance. In addition, in the stacking section for good and bad paper, empty paper is placed in the initial standby position. The carrier plates are kept on standby, and the stacked sheets that reach a predetermined number of sheets are After the operation is completed, the machine is carried out to the standby position and moved to the operating position. Also before The carrier plate that has become empty due to the transfer of the recorded stack sheet is It passes under the lifting table (carrier plate) and is sent back to the initial standby position. Wait in an empty state. The above cycle is repeated sequentially, and the stacked sheets are automatically transported. Loading and unloading is performed continuously. Note that the carrier plate 3 is provided in a plurality (usually The common ones consisting of 2 pieces) are sequentially recycled, and the stacked sheets 9, 10 , 11 are carried onto the carrier plate in a stacked state on the sheet holder 8, or are placed in a key position. removed from the carrier plate.
