SHEET PROCESSING DEVICE AND IMAGE RECORDING DEVICE TO BE CONNECTED THERETO

摘要

PURPOSE:To improve the working efficiency of a sheet processing device for housing sheets on a discharged sheet housing tray and an image recording device for discharging the sheets to that sheet processing device. CONSTITUTION:A sheet processing device U1 is provided with a discharged sheet size storage means 212 for storing the cross directional sheet size SH of a sheet (Si) discharged from an image recording device U2 and a tamper movement control device 215 for moving a tamper (Ta) for the tamping operation between the waiting position and the sheet registering position in response to the sheet size SH. The sheet processing device U1 has a tamper movement control device 215 for comparing the cross directional sheet sizes SL and SH of the sheet at the largest size among the sheets housed in the discharged sheet housing tray with a sheet size comparing means 213, and for performing the tamping operation of the tamper (Ta) in the case of SH>=SL, and for stopping the tamper (Ta) in the case of SH
