摘要： In a fixing apparatus of the present invention, an end section fixing control temperature changing section selects an end section fixing control temperature in accordance with the number of paper sheets that have been processed in one continuous printing process. A sub-heater on/off determining section turns on or off a sub-heater in accordance with a temperature detected by an end section temperature sensor and the end section fixing control temperature selected by the end section fixing control temperature changing section. This prevents the occurrence of fixing failure even in continuous printing with respect to large-size paper sheets in an arrangement in which a temperature sensor is disposed outside a maximum-size sheet passing region at an end section of a fixing roller and controls energization of a heater which is disposed corresponding to the end section of the fixing roller in accordance with a temperature detected by the temperature sensor.

摘要： A vacuum high-speed feeding apparatus equipped structure for moving suction nozzles attached to a cylindrical body towards sheet feeding rollers. The application of suction force is suspended upon detection that a drawn sheet has been caught and its conveyance has been stated by feeding rollers. This is done by detection of a leading edge of the sheet by a first sensor. The cylindrical body is restored to its home position when feeding of the sheet by a given distance is detected by a second sensor. The suction force is again applied when passage of the rear edge of the sheet through the feeding rollers is detected by the first sensor.

摘要： A sheet post-processing apparatus is provided with a discharge tray which can be selectively moved between a processing mode position corresponding to a processing mode and a non-processing mode position corresponding to a non-processing mode. The apparatus is also provided with a control device which controls a tray drive unit which drives so as to set the discharge tray in the processing mode position when the processing mode is selected, while in the non-processing mode position when the non-processing mode is selected. The apparatus offers an improved discharging efficiency of processed sheets from a processing tray to the discharge tray in the processing mode and an improved aligning facility of sheets discharged on the discharge tray in the non-processing mode.

摘要： A sheet post-processing apparatus is arranged such that in the non-staple mode, the leading edges of the sheets transported from the transport rollers are directed so as to be sandwiched between the upper and lower discharge rollers by a movable sheet guide in a non-staple mode position and the sheets are discharged onto a stacking tray through the upper and lower discharge rollers. In the staple mode, the leading edges of the sheets is directed to a discharge opening formed between the upper discharge roller and the movable sheet guide by the movable sheet guide in the staple mode position so as to be dropped onto the staple tray. After being processed by the stapler, the sheets are pushed by a pushing member through the discharge opening onto the stacking tray. As a result, the movements of the upper and lower discharge rollers are stabilized, and the sheets can be prevented from being stuck between the upper and lower discharge rollers and or being slanted when being discharged, thereby achieving a desirable discharge of the sheets in the non-staple mode.
