PURPOSE:To improve controllability of an output paper sheet in a stacker part by outputting the paper sheet to be accumulated in the stacker part, setting the paper sheet in its upper limit weight, thickness and number of sheets to an arbitrary quantity, easily handled by an operator, and controlling a paper sheet output for the stacker part. CONSTITUTION:A paper sheet is accumulated one by one on middle bottom plates 29a, 29b of containers 30a, 30b in stacker parts 25a, 25b, and detecting the paper sheet for an increase of its accumulating thickness and weight by light emitting parts 26a, 26b, light receiving sensor lines 27a, 27b and pressure detecting parts 28a, 28b, their detecting value is fetched to a CPU in a printer control part. Subsequently, these detecting values are compared with a preset value in a panel part of the printer control part 1, when the detecting value exceeds the preset value, the paper sheet is switched from one stacker part 25a (or 25b) to the other stacker part 25b (or 25a), fed successively and accumulated in this switched stacker part 25b (or 25a). |
