摘要： Near a discharge means (48) for discharging paper (P) with an image formed thereon, there is provided a punching means (7) for punching holes. The drive of the discharge means (48) is scontroled to punch holes in the trailing portion of the paper (P), without causing crease and tear or change in the quality of the paper (P). Said punching means (7) includes punching cutters (72) and a punching die (74). The punching cutters (72) and the punching die (74) are provided in a unit (U) which can be drawn out of a casing (1) covering the punching means (7). With the unit (U) drawn out of the casing (1), jam recovery can be easily executed. The unit (U) is moved in the width direction of the paper (P), thereby to adjust a position of punch holes. A collecting box (76) for collecting paper scraps (P1) is disposed in the unit (U). If the collecting box (76) is turned or the opening (76a) thereof is lifted up when the unit (U) is turned, the paper scraps (P1) therein will not fall off. Delaying timing for plural punching cutters (72) to punch holes can reduce load on the drive system.

摘要翻译：在用于排出形成有图像的纸张（P）的排出装置（48）附近，设置有用于打孔的打孔装置（7）。排出装置（48）的驱动被控制为在纸张（P）的尾部打孔，而不会引起纸张（P）的折痕和撕裂或改变质量。所述冲孔装置（7）包括冲孔刀（72）和冲孔模（74）。冲切刀72和冲压模74设置在能够从覆盖冲压装置7的外壳1中抽出的单元U中。将单元（U）从外壳（1）中抽出后，可容易地执行卡纸恢复。单元（U）在纸张（P）的宽度方向上移动，由此调整打孔的位置。用于收集废纸（P1）的收集箱（76）设置在单元（U）中。当单元（U）转动时，如果收集箱（76）转动或其开口（76a）被抬起，则其中的纸屑（P1）不会掉落。延迟多个冲孔刀（72）到冲孔的时间可以减小驱动系统上的负载。

摘要： An apparatus for regulating the movement of a movable member includes a drive device (52) for moving the movable member in a first direction from a rest position to an operative position and for moving the movable member in a second direction, opposite to the first direction, from the operative position toward the rest position. A first detector (72) detects the presence of the movable member at the rest position. A second detector (73) detects the presence of the movable member at a location adjacent the rest position but upstream thereof with respect to the second direction. A control arrangement (99) is operatively connected to the drive device (52) and to the first and second detectors (72, 73) to operate the drive device to move the movable member in the first direction and then in the second direction, to stop the drive device upon detection of the movable member moving in the second direction at the location by the second detector (73), whereafter the movable member continues movement by inertia in the second direction from such location to the rest position and is detected thereat by the first detector (72), and to, if the movable member is not detected at the rest position by the first detector (72) within a predetermined time period after the detection by the second detector (73), again starting the drive device to move the movable member in the second direction until detection thereof by the first detector (72).

摘要： A copying machine which develops an electrostatic latent image corresponding to an original image into a toner image, transfers the toner image on the copying paper (P) and fuses the toner image later on the copying paper (P) by means of a heating and fusing device (38), detects types of copying papers (P) to be transferred by the toner image and when the copying paper (P) is large in size, a fixed standstill time is arranged between the scanning and exposing operation of an original and a restoring operation to a home position is made and a fusing operation is prevented without fail when a temperature of the heating and fusing device (38) drops below a fusing temperature.
