摘要： An image forming apparatus includes a photoreceptor drum, a developing roller, a registration roller for positioning and conveying the paper and a drive controller for controlling the drive of the registration roller. The registration roller conveys the paper so that its leading end collides with the photoreceptor drum. The drive controller corrects the timing of driving the registration roller based on the detected eccentric variation of the peripheral surface of the photoreceptor drum and the rotational phase. The drive controller may acquire the eccentric variation as external data instead of detecting it.

摘要： In a paper-punching device for use in an image-forming apparatus, the rear edge of a sheet of paper that is being transported through a transport guide is detected by the photosensor. After a predetermined time has passed since the detection, a punching device is activated. At this time, a punching member is depressed downward, and a punching blade attached to its top penetrates through the sheet of paper, thereby forming a punch hole. Even during the punching operation, transport rollers continue to rotate. Therefore, when the sheet of paper is caught by the punching blade, the transport rollers are allowed to slip predetermined amount with respect to the paper. For this reason, at least one of the transport rollers is made of a foamed material. With this arrangement, since the punching operation is carried out on the rear side of the sheet of paper, it becomes possible to reduce the occurrence of paper jams even if sheets of paper are transported in succession. Further, the punching operation is carried out while the paper is being transported; this makes it possible to provide a high-speed operation. Further, even if the sheet of paper is caught by the punching blade, it is not damaged because of the slip that is provided.
摘要翻译：在用于图像形成装置的打孔装置中，通过光传感器检测正在运送通过传送引导件的纸张的后边缘。从检测开始经过规定时间后，冲孔装置被激活。此时，冲压构件向下压下，并且其顶部附着的冲切刀片穿过纸张，从而形成冲孔。即使在冲压操作期间，输送辊继续旋转。因此，当纸张被冲切刀片卡住时，允许输送辊相对于纸张滑动预定量。为此，至少一个传送辊由发泡材料制成。通过这种布置，由于在纸张的后侧执行冲压操作，所以即使连续传送纸张也可以减少卡纸的发生。此外，在纸张运送时进行冲压操作; 这使得可以提供高速操作。此外，即使纸张被冲压刀片卡住，也不会因为设置的滑动而损坏纸张。

摘要： An image forming apparatus provided with a photoreceptor with an internal gear includes the internal gear in a photoreceptor drum, a pinion gear in engagement with the internal gear, and a cleaning unit and a developer unit which apply contact pressure onto the photoreceptor drum. The pinion gear is provided in such an area that a resulting force of the contact pressure respectively applied from the process elements does not cause a distortion of the photoreceptor drum which exceeds an axial backlash determined in initialization according to a distance between axes of the pinion gear and the internal gear. The described arrangement prevents interference between non-driving surfaces of the internal gear and the pinion gear. As a result, a smooth rotary motion of the photoreceptor drum can be ensured, thereby preventing an image defect caused by an unstable rotary motion of the photoreceptor drum.
