A method of grouping sheet units, which belong together in sheet groups, a sheet stream comprising two superposed sheet units each by means of a grouping unit, a grouping unit for a sheet handling system, and a sheet handling system that allow a high processing speed and a high cycle efficiency of a sheet handling system are disclosed. A sheet unit can be held back in the grouping unit. Depending on whether the downstream subsequent sheet units transferred into the grouping unit belong to a sheet group, the held-back sheet unit can be released by itself and together with one or together with both downstream subsequent sheet units.

A sheet processing apparatus includes a buffering portion having a reverse conveyance roller pair and an intermediate roller pair, with the reverse conveyance roller pair reversing a conveyance direction of a sheet received from a first conveyance path and delivering the reversed sheet into a second conveyance path and being configured to come into contact with and be separated from each other. The intermediate roller pair is disposed in the second conveyance path and disposed upstream of a conveyance roller pair in a sheet conveyance direction, and the reverse conveyance roller pair is caused to nip a first sheet and a second sheet by causing the reverse conveyance roller pair to abut each other after receiving the second sheet by the reverse conveyance roller pair from the first conveyance path in a state in which the intermediate roller pair nips the first sheet reversed by the reverse conveyance roller pair and the reverse conveyance roller pair is separated from each other.

A printing apparatus includes a printing unit configured to print an image on a sheet; a first exit path from which the sheet with the image printed thereon by the printing unit is discharged while being reversed; a second exit path from which the sheet with the image printed thereon by the printing unit is discharged without being reversed; and a switch member configured to be pivotably arranged so as to switch the first exit path and the second exit path. The first exit path passes above a pivot center of the switch member, and the second exit path passes below the pivot center.

A printing apparatus includes: a printing unit; a first conveyance unit configured to convey a sheet to the printing unit with nipping the sheet; a second conveyance unit provided on a downstream side of the first conveyance unit in a conveyance direction of the sheet, and configured to convey the sheet with nipping the sheet; a third conveyance unit provided on a downstream side of the second conveyance unit in the conveyance direction, and configured to convey the sheet with nipping the sheet; and a switching unit configured to switch a nip state of the second conveyance unit and a released state in which the nip state is released. When the sheet is conveyed by the third conveyance unit, the switching unit switches the nip state and the released state in accordance with a length of the sheet.

In an image forming apparatus capable of turning over a sheet to form images on both sides of the sheet, when duplex printing is executed successively on three or more sheets, a controller causes a first sheet conveyed from an image forming unit and a second sheet conveyed from the image forming unit to be guided into a first path by positioning a guide member in a first position, and then conveyed into a third path by a first roller, and causes a third and subsequent sheets conveyed from the image forming unit to be guided into a second path by positioning the guide member in a second position, and then conveyed into the third path by a second roller.

The present invention is to provide a sheet conveying apparatus capable of reliably detecting a full-load state of a storage section for storing sheets discharged from a sheet conveyance path when an abnormality such as multi feed is detected, a sheet feed apparatus is provided with a multi feed sheet storage section disposed below a common conveyance path to store multi-fed sheets with multi feed detected, and a flap member rotating between a first rotation position for supporting a sheet in the common conveyance path to be able to convey to the downstream side in a conveyance direction, and a second rotation position for guiding to the multi feed sheet storage section, and determines that the multi feed sheet storage section is in a full-load state in detecting that the flap member does not return to the first rotation position.

A first unit includes a receiving portion that receives a medium to be processed, a drying unit that processes the medium received from the receiving portion, and an end stitching unit that processes the medium received from the receiving portion or the medium processed by the drying unit. The processing performed by the drying unit is processing of drying the medium, the drying unit is located vertically below the end stitching unit, and the drying unit and the end stitching unit have a portion overlapping when viewed in a vertical direction.

A printer having front-end paper feeding and front-end paper outputting and being capable of changing a paper discharge path, said printer comprising a housing (10) and a paper discharge unit (40), the paper discharge unit (40) comprising a first paper discharge mechanism (401) and a paper discharge channel (50) which consists of upper and lower casings (1011, 1012), a front end surface of the housing (10) being a vertical flat surface A, a paper feed port (30) and a paper output port (20) being horizontally arranged on the flat surface A, the paper feed port (30) being located beneath the paper output port (20), the paper discharge channel (50) at the front of the first paper discharge mechanism (401) being provided with a paper conveyance system capable of changing a paper discharge path.

Disclosed are a cash box and a cash recycling and handling device; the cash box includes a box body, a first cash storage cavity, a second cash storage cavity, a transfer passage, a first switching member and a linkage assembly; a first lifting platform is provided inside the first cash storage cavity, and the first lifting platform is capable of moving back and forth in the preset direction and can be located at a first dispensing position; when the first lifting platform is in the first dispensing position, it is engaged with the linkage assembly to rotate the first switching member to a first position, and when the first lifting platform moves to a first inlet, the linkage assembly rotates the first switching member to a second position.

An image forming apparatus includes: as a conveyance path to convey an object formed with an image by an image former, a bent conveyance path exhibiting a bent shape; and a straight conveyance path connected to a downstream side of the bent conveyance path and exhibiting a straight shape, wherein the bent conveyance path and the straight conveyance path each include: a pair of guide parts facing each other to form the bent conveyance path and the straight conveyance path; and a plurality of friction reducing parts that are arranged in a conveyance direction on one of a pair of the guide part and are able to abut with an image forming surface of the object conveyed between a pair of the guide parts.
