Abstract

PURPOSE:To prevent the occurrence of jamming in the middle of carriage, and to prevent breaking of a sheet medium during the alignment of width in post-treatment by detecting the lateral position of the sheet medium, and by stopping the carriage of the sheet medium when the amount of skew of the medium exceeds a standard value. CONSTITUTION:A carrier roller 12 is rotated by the driving of a motor 13, and a sheet medium 11 is carried thereby. During the carriage, it is detected by a medium position detecting means 15 which of the right and left sensors 14a or 14c is turned 'OFF' by the passing of the sheet medium 11. When either of these is turned 'OFF', time counting is started by skew counting means 19 until both of the right and left sensors 14a and 14c are turned 'OFF'. The carrying speed of a motor 13 is detected by the means 17, and the amount of skew is calculated from the counted time and speed. If the amount of skew is not more than a standard value, taking in and carrying of the sheet medium 11 are continued, while if it is not less than the standard value, carriage is stopped being defined as a skew error, whereby the occurrence of jamming or the breaking of the sheet medium 11 can be eliminated.

As shown in the figure, when the sheet-like medium 11 is manually inserted from the insertion port gate portion while the motor 13 is not rotating (step 5TI), the three sensors 14a, 14b, and 14c detect the sheet-like medium 11. The medium 11 is detected and turned on and off depending on its presence or absence. The medium position detection means 15 includes three sensors 14a,
14b, 14c are all turned on or not (step 5T2). If not all are turned on, the operation returns to repeating manual insertion again, and when all are turned on, a control signal is sent to the drive control means 16. The feeding motor 13 is rotated and the conveying rollers 12.12 start conveying (steps ST3, 5T4). Next, while the conveyance is being performed, the medium position detection means 15 detects the sheet-like medium 1.
1 passes, and it is detected whether either the right or left sensor 14a or 14C is turned off.Step 5T5) When either of them is turned off, the skew amount counting means 17 starts counting the time, and the right and left sensor 14a, 14C is turned off. Count the time (1) until both 14a* and 14c turn off (step ST6. ST?
