PURPOSE:To reduce the rearranging time of frames so as to facilitate an operation by fixing a rear frame with respect to a sheet feeding direction and operating right and left frames respectively by means of buttons with said rear frame as a reference. CONSTITUTION:The movement of a guide 1 and a guide 2 in the right and left directions are adjusted via sliders 1b, 2b. And, their positions are carried out by detecting them by means of encoders 11a, 11b provided on one slide end face each of connecting rods 10a, 10b. The driving side end parts of threaded rods 1c, 2c are rotatably supported by both end parts of a beam 8e while the other end parts are rotatably supported on the bearings 1e, 2e of the sliders 1b, 2b respectively. Equally, the driving side end parts of threaded rods 1d, 2d are rotatably supported by machine frames Fa, Fb while the other end parts on the bearings 1e, 2e of the sliders 1b, 2b respectively. And, the framing of the front and rear and right and left frames of a magazine is automatically carried out according to the size of a sheet through the button operation of their respective motors with brakes.
