Abstract

PURPOSE:To process jam paper or the like immediately by stopping a main motor immediately in case of detecting no preceding paper in a copying machine at the incorrect paper feeding. CONSTITUTION:At the input of a signal from a paper discharge sensor 15, (-1) is added to a counted value of a paper counter to subtract the number. After passing a prescribed time, e.g. 300ms, from paper feeding, a control part 17 judges incorrect paper feeding at the time-up of an incorrect paper feeding detecting timer, checks the counted value of the counter, and when the value is (+1), stops the main motor 9 immediately on the basis of the fact that the paper has been already discharged or no preceding paper exists. When the counted value of the counter is (+2), the control part 17 judges that the preceding paper exists in the copying machine, and when a prescribed time has been passed or the paper discharge sensor 15 is turned on, stops the main motor 9.

By this control, the main motor 9 is driven, and one of the clutches 10 and 11 is turned on, and the paper feed rolls 12 and 13 are turned on.
One of them is driven. A misfeed detection timer (for example, the CPU 17e counts the clock) is activated by the output of the drive signal of the clutch 10 or Fill,
The tie 1- is reset by turning on the copy paper feed detection switch 140 (copy paper detection) placed in front of the register roll 6a. At the same time, the output of the clutch drive signal causes the copy paper counter (CP
Number of pairs of U17c I1/? is stored in the RAM 17 d) is set to +1, and the fact that one sheet of copy paper has been fed is set to 1.
1AM17dK is memorized. The fed copy paper 1 (is transferred by the transfer device 6 and fixed, then the copy paper ejection sensor) 5
It is then discharged. When the copy paper is ejected, -1 is added to and subtracted from the count value of the copy paper counter depending on the reliability of the copy paper ejection sensor 15. A predetermined period of time, for example, 300 ms has passed since the copy paper was fed.
7, when the misfeed detection timer times up (when the switch 14 is turned on within this time),
The control unit 17 determines that there is a misfeed 1~, and checks the count value of the copy paper counter, and if the count value is +1, the preceding copy paper has already been ejected, or
The main motor 9 is immediately stopped based on the fact that the copy paper is not ahead. On the other hand, when the count value of the copy paper counter is +2, it is determined that there is a preceding copy paper in the copying machine, and the main motor 9 is stopped when a predetermined time has elapsed or when the copy paper discharge sensor 15 is turned on.
