  • Publication number: 20200290393
    Abstract: An image forming apparatus includes a processing tray, a post-processing controller, and a detection sensor. The processing tray is configured to support a sheet or a sheet bundle on which a post-processing is to be executed. The post-processing controller is configured to execute the post-processing on the sheet positioned on the processing tray. The detection sensor is configured to detect an object in a predetermined detection range including a space above the processing tray. The post-processing controller stops execution of the post-processing when the detection sensor detects the object at a determination timing other than a timing at which passage of the sheet or the sheet bundle through the detection range is estimated.

  • Publication number: 20200270080
    Abstract: According to one embodiment, a manual sheet feeding device includes a pressure plate, a first displacement member, a first input member, a second displacement member, a second input member, a coupling member, a restricting member, and an elastic member. The first displacement member displaces the plate from a first side to a pressure and a release position. The first input member displaces the first displacement member to a first and a second position. The second displacement member displaces the plate from a second side to the pressure and the release position. The second input member displaces the second displacement member to a third and a fourth position. The coupling member gives the second input member a second displacement amount larger than a first displacement amount. The restricting member restricts a displacement amount of the second input member. The elastic member elastically deforms when the amount of displacement is restricted.

  • Patent number: 10214377
    Abstract: A sheet processing apparatus includes a processing tray, a conveyance roller, an extrusion member, a pinch roller and a controller. The conveyance roller is arranged at a downstream side of the processing tray in a sheet conveyance direction, and conveys the sheet. The extrusion member extrudes an end of an upstream side in the sheet conveyance direction of the sheet placed on the processing tray to the downstream side. The pinch roller moves to a rotation position at the time of conveying the sheet by the conveyance roller to sandwich the sheet with the conveyance roller. The controller controls the pinch roller and the conveyance roller to convey the sheet using the pinch roller and the conveyance roller when the sheet placed on the processing tray is conveyed to the downstream side in the sheet conveyance direction.

  • Publication number: 20190004469
    Abstract: A sheet punching device includes a punching unit, a cover member, an opening and closing sensor, a dust box, and a controller. The punching unit forms a punched hole in a sheet. The cover member can open and close the punching unit. The opening and closing sensor detects an open state of the cover member of the punching unit. The dust box is arranged in the punching unit and houses punch waste of the punched hole. The controller instructs continuation of a job of an image processing apparatus even if the opening of the cover member is detected by the opening and closing sensor without using the punching unit.

  • Publication number: 20180370747
    Abstract: A post-processing apparatus includes a processing tray for stacking a sheet and a detection sensor for detecting the presence or absence of the sheet placed on the processing tray. The post-processing apparatus includes a pinch roller for moving towards the processing tray if the detection sensor does not detect the sheet, and a longitudinal alignment roller configured to rotate by a predetermined amount while sandwiching the sheet in the processing tray with the pinch roller to elongate the sheet. By holding a rear end of the sheet in the processing tray with a paddle section and elongating the sheet towards the downstream side with the longitudinal alignment roller, the presence or absence of the sheet is detected by the detection sensor.
