摘要： An envelope processing apparatus (100) includes a conveyance roller (124) that conveys an envelope to an enclosing position. A first envelope length calculator (1501) calculates a first envelope length of the envelope in an envelope conveyance direction in which the envelope is conveyed in a close state in which a flap of the envelope closes. A flap opener (180) opens the flap while the conveyance roller (124) conveys the envelope. A second envelope length calculator (1502) calculates a second envelope length of the envelope in the envelope conveyance direction in an open state in which the flap opens. A controller (150) calculates a flap length of the flap in the envelope conveyance direction based on the first envelope length and the second envelope length. The controller (150) controls enclosing of an enclosure into the envelope based on the flap length.

摘要： A medium processing apparatus (100) for processing a medium ejected from an image forming apparatus includes conveying means (11, 12, 13), a slit (23), medium processing means (19, 26), a stopper (25a, 25b), and a plurality of detecting means (50). The conveying means (11, 12, 13) conveys the medium ejected from the image forming apparatus. The slit (23) communicates with an opening of a housing (25) into which a medium is manually inserted from outside. The slit (23) includes a placement face (23a) on which the inserted medium is placed. The placement face (23a) has a first side and a second side orthogonal to the first side. The first side and the second side are not parallel to a direction in which a side face of the housing (25) extends. The medium processing means (19, 26) processes the medium conveyed by the conveying means (11, 12, 13) or the medium placed on the slit (23). The stopper (25a, 25b) regulates edges of the medium along the first side and the second side of the placement face (23a). The plurality of detecting means (50) is disposed on the stopper (25a, 25b) to detect the medium.

摘要： A sheet processing device (20 and 30) includes an upstream device (20), a downstream device (30), and a controller (100). The upstream device (20) includes multiple rollers (22a, 22b, 23, 24, 25) to convey a sheet in a conveyance direction and perform a sheet processing. The downstream device (30) is downstream from the upstream device (20) in the conveyance direction. The downstream device (30) includes a sheet sensor (29) to detect the sheet. The controller (100) controls a timing to rotate the multiple rollers (22a, 22b, 23, 24, 25) of the upstream device (20) to perform the sheet processing in response to a detection of the sheet by the sheet sensor (29).

摘要： A sheet folding apparatus (20) includes a conveyor (22), a first folding roller (23), a second folding roller (24), a third folding roller (25), a guide (26), a motor (24a), and a driving force transmission mechanism (28a, 28b). The motor causes the second folding roller to perform either forward rotation in which the second folding roller rotates to convey a sheet on a main conveying path in a conveying direction and to convey the sheet on a reflux conveying path from a joining position toward a branching position or backward rotation in a direction opposite to the forward rotation. The driving force transmission mechanism rotates the guide toward a first posture from a second posture in conjunction with the forward rotation of the second folding roller and rotates the guide from the first posture toward the second posture in conjunction with the backward rotation of the second folding roller.

摘要： An envelope processing apparatus (100) includes a conveyance roller (124) that conveys an envelope to an enclosing position. A first envelope length calculator (1501) calculates a first envelope length of the envelope in an envelope conveyance direction in which the envelope is conveyed in a close state in which a flap of the envelope closes. A flap opener (180) opens the flap while the conveyance roller (124) conveys the envelope. A second envelope length calculator (1502) calculates a second envelope length of the envelope in the envelope conveyance direction in an open state in which the flap opens. A controller (150) calculates a flap length of the flap in the envelope conveyance direction based on the first envelope length and the second envelope length. The controller (150) controls enclosing of an enclosure into the envelope based on the flap length.
