IPC: B65H9/14
Filed: 1985-04-18
Abstract: PURPOSE:To prevent a lowering of copy efficiency by comparing a re-transport timing value of a re-transported sheet with a preset value, and generating a release signal when it exceeds the preset value to complete copy operation, so that work can be continued without stopping the copy operation. CONSTITUTION:An operator pulls out a sheet, one side of which is subjected to copy action, and the sheet is completely drawn out of a pair of discharge rollers 33. And if the sheet is not re-transported to a main body of a copying machine, when the trailing end of the sheet is detected by a sheet trailing end detecting sensor 35, the pair of discharge rollers 33 are reversed by reversing of a forward and backward rotating DC motor, and time counting for transport timing value is started at a control unit C. If the sheet is not detected by a timing detecting sensor 28, when the timing value amounts to a preset value previously set at a setting device X, it is judged that the sheet is not re- transported normally, the reversing of the paired discharge rollers 33 is stopped, and a command for copying the back side of the sheet is released. Further, the machine is again restored to the condition of making a copy on the first surface of a sheet in both-sided copying mode. Thus, copy efficiency can be improved.
