摘要： An image forming system which is capable of, when a manual stapling process is to be carried out on sheets, reducing waiting time for a user and decreasing power consumption. The image forming system has an image forming apparatus, which forms images on sheets, and a sheet post-processing apparatus. When the sheet post-processing apparatus is to shift into a power-saving state, a movable stapler is moved to a manual stapling position. When it is detected that sheets have been set into a sheet setting unit in a state in which the image forming apparatus and the sheet post-processing apparatus have shifted into the power-saving state, the image forming apparatus is held in the power-saving state, and the sheet post-processing apparatus is returned from the power-saving state.

摘要： A sheet feeder which is capable of accurately detecting multi-feed of sheets even when the distance between sensors is changed. The sheet feeder includes a sheet container for holding a stack of sheets. Ultrasonic sensors for transmitting and receiving ultrasonic waves, respectively, are provided on a conveying path. The ultrasonic sensor as a transmitter transmits ultrasonic waves to a sheet being fed and conveyed. A reception circuit detects a level of ultrasonic waves received by the ultrasonic sensor as a receiver. The level of ultrasonic waves detected after lapse of a predetermined time from transmission of ultrasonic waves is compared with a predetermined threshold value to determine multi-feed of sheets. A distance between the ultrasonic sensors is detected, and at least one of the predetermined time period and the predetermined threshold value is corrected based on the detected distance between the sensors.

摘要： Provided is a sheet material binding apparatus capable of shortening a user's waiting time required to bind sheets through a manual operation with a movable stapler. A CPU (162) of a sheet material binding apparatus (50) monitors whether or not an image forming apparatus (1) can execute image formation processing. When the image forming apparatus (1) can execute the image formation processing, the movable stapler is arranged at a standby position close to the image forming apparatus (1). When the image forming apparatus (1) cannot execute the image formation processing, on the other hand, the movable stapler is arranged at a position for performing the manual operation, to thereby bind the sheets through the manual operation immediately.

摘要： Provided are a sheet feeding device and an image forming apparatus that are capable of accurately detecting an abnormality of a feeding state without erroneously detecting when a trailing edge of a preceding sheet and a leading edge of a subsequent sheet are fed in an overlaid state. The sheet feeding device includes ultrasonic wave sensors 6 and 7 that detect an overlaid state of a preceding sheet Sa and a subsequent sheet Sb fed from feeding portions 51, 317 to 319 and a controller 1 that continuously performs a detection of the overlaid state of a sheet fed from the feeding portion at a predetermined number of detecting points along a sheet conveying direction at every predetermined time and determines a number of detecting points where detects. Based on the determined number of detecting points, the controller determines that the overlaid state is normal or abnormal.
