ADDITIVE PAPER FEEDING DEVICE

PROBLEM TO BE SOLVED: To provide an additive paper feeding device capable of recognizing the number of stages connected by an image forming device, and controlling paper feeding. SOLUTION: A control signal from an image forming device (not illustrated) is inputted to a selector 105. A stage number (n) of an additive paper feeding device is set by a switch 103. The selector 105 outputs a specified control signal through a driver 106 to a paper feeding motor 110 and a paper feeding clutch 111 based on select input from the switch 103. A comparator 104 compares a paper feeding select signal A from the image forming device with a signal B from the switch 103, and when the signal A coincides with the signal B, output of a paper size sensor 108 is sent through a driver 107 to the image forming device.
