摘要： A paper processing device includes a processing unit, a paper ejection roller, a sorting mechanism, a paper overlapping mechanism, and a control unit. The processing unit performs predetermined processing upon sheets of paper being conveyed one at a time along a paper conveyance direction. The roller discharges the sheets in the paper conveyance direction, after completion of processing by the processing unit. The sorting mechanism shifts the roller to and fro between an initial position and a sorting position in a direction orthogonal to the paper conveyance direction. The overlapping mechanism superimposes, between the processing unit and the roller in the paper conveyance direction, a predetermined number of sheets of paper upon which processing has been completed. The control unit superimposes a predetermined number of sheets of paper by operating the overlapping mechanism, before shifting the roller from the initial position to the sorting position with the sorting mechanism.

摘要： A sheet feeder has a feed passage and includes feed roller pairs, sensors, and a controller. The feed roller pairs are arranged along the feed passage and feed sheets of paper in a feed direction along the passage by nipping the sheets. Each of the sensors is fitted at or near one of the feed roller pairs and senses a specified point on each of the sheets when the sheet is nipped by at least the associated roller pair. The controller includes a memory for storing reference feed timings as proper feed timings at each of which the specified points on the sheets should pass one of the sensors. The controller finds the real feed timing when each of the sensors senses the specified point on the sheet nipped by at least the associated roller pair. When each of the sensors senses the specified point on the sheet nipped by at least the associated roller pair, the controller finds the time difference between the associated reference feed timing and the associated real feed timing and controls, according to the found time difference, the feed speed at which the feed roller pair or pairs nipping the sheet feed it.

摘要： A duty correction circuit is formed using at least one delay circuit, which is constituted of a first inverter including three transistors of different conduction types and a second inverter including three other transistors of different conduction types and which delays and adjusts an input clock signal at the leading-edge/trailing-edge timing so as to convert it into an output clock signal based on a first or second bias voltage produced by a bias circuit detecting the duty ratio of the output clock signal. The duty correction circuit decreases the high-level period of the output clock signal having a high duty ratio based on the first bias voltage. Alternatively, the duty correction circuit increases the high-level period of the output clock signal having a low duty ratio based on the second bias voltage.

摘要： Disclosed is a timing control circuit that receives a first clock having a period T1, a group of second clocks of L different phases spaced apart from each other at substantially equal intervals and selection signals m, n supplied thereto and generates a fine timing signal delayed from the rising edge of the first clock signal by a delay td of approximately td=m·T1+n·(T2/L). The timing control circuit includes a coarse delay circuit and a fine delay circuit. The coarse delay circuit includes a counter for counting a rising edge of the first clock signal after an activate signal is activated and generates a coarse timing signal whose amount of delay from the first clock signal is approximately m·T1. The fine delay circuit comprises L-number of multiphase clock control delay circuits disposed in parallel, delays by n·T2/L the timing of sampling of the coarse timing signal by respective clocks of the group of L-phase second clocks, and takes the OR among the resulting delayed pulses to thereby produce the fine timing signal.

摘要： In an image forming apparatus of the present invention, an idle roller once stops rotating when a front edge of a sheet conveyed reaches the idle roller. The idle roller restarts rotating at such a timing that a front edge of a toner image on a photoreceptor and a front edge of an image writing position on the sheet are aligned with each other. Then, even if a rear edge of the sheet is still in the idle roller, the idle roller stops rotating when the front edge of the sheet is sandwiched between a transfer roller and the photoreceptor. By carrying out such operations, it is possible to avoid by a very simple way an occurrence of a slip phenomenon that is a phenomenon of slipping of the sheet with respect to the photoreceptor while suppressing a reduction in image quality as much as possible. In addition, it is also possible to surely secure a blank space formed at a rear edge portion of the sheet.
摘要翻译：在本发明的图像形成装置中，当传送的纸张的前缘到达空转辊时，空转辊一次停止旋转。空转辊重新开始旋转，使得感光体上的调色剂图像的前边缘和片材上的图像书写位置的前边缘彼此对准。然后，即使片材的后边缘仍然在空转辊中，当片材的前边缘夹在转印辊和感光体之间时，空转辊停止旋转。通过进行这种操作，可以通过非常简单的方式避免出现作为尽可能多地抑制图像质量降低的片材相对于感光体的现象的滑动现象。此外，还可以确保形成在片材的后边缘部分处的空白空间。
