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.

It is driven by a driving means such as a motor 13. Three sensors 14a, 14b, and 14c are provided at the insertion gate in front of the conveyance rollers 12 and 12 to detect the inserted sheet medium 11 from below. These sensors 14a, 14b, and 14c are arranged in a line in a horizontal direction perpendicular to the conveyance direction, and detect the right, center, and left positions of the sheet-like medium 11 passing through, respectively. Such sensors 14a, 14b,
For example, an optical sensor is used as the sensor 14c, which turns on when the sheet-like medium 11 is detected and turns off when it passes. These sensors 14a, 14b, 1
The detection signal 4c is transmitted to the medium position detection means 15. This medium position detection means 15 includes three sensors 14a,
The presence of the sheet-like medium 11 is detected in accordance with the on/off states of 14b and 14c, and a control signal for starting conveyance is given to the drive control means 16. Further, the detection signal from the medium position detection means 15 is given to the skew amount counting means 17 as a time count start signal for determining the skew amount of the sheet-like medium 11 . This skew amount counting means 17 includes right and left sensors 14.
Count the time difference between on and off of motors a and 14c, and
The amount of skew is determined from the conveyance speed of No. 3, and this amount of skew is compared with a predetermined reference value. Based on the comparison result, the drive control means 16
