A sheet detecting apparatus including: a detection unit including a lever member having an abutment surface abutting a conveying sheet and a holding member configured to hold the lever member, the detection unit moved by the lever member pushed by the sheet; a first urging portion configured to urge the holding member to a waiting position after the sheet is separated from the abutment surface; a support portion configured to support the lever member movable with respect to the holding member to move the lever member to a retracted position for allowing the sheet to pass the lever member contacting a surface of the sheet when the holding member is in the waiting position; and a second urging portion configured to urge the lever member so that the lever member is moved from the retracted position to a position in which the abutment surface abuts a succeeding sheet.

A sheet conveying apparatus includes a discharge tray having a support surface supporting a sheet discharged by a discharge unit of a conveyor. A first stopper is provided on the support surface. A movable member is provided on the support surface between the discharge unit and the first stopper. The first stopper is changeable between a first position at which the first stopper protrudes from the support surface and a second position at which the first stopper is stored in the discharge tray. The movable member is changeable between a third position at which the movable member protrudes from the support surface and a fourth position located nearer to the support surface than the third position. The first stopper is changed from the first position to the second position in conjunction with a change of the movable member from the third position to the fourth position.

In one example, a media feed system includes a pick arm that is adjustable at a pivot and operable to maintain a distance between a pick roller and a separation wall as the pick arm changes orientation. In another example, a media feed system may include a pick arm, a pick roller coupled to the pick arm, a pivot coupled to the pick arm, and a plate coupled to the pivot via a pin and slot interface. In that example, a slot of the pin and slot interface is to adjust position of the pivot and adjust orientation of the pick arm.

A sheet conveying apparatus including: a locking member having an abutment surface abutting a sheet to correct skew feed of the sheet; a holding member configured to hold the locking member to rotate from a waiting position when the locking member is pushed by the sheet; a roller pair configured to nip the sheet abutting the abutment surface; a first urging portion configured to urge the holding member to the waiting position; a movable support portion configured to support the locking member in a manner that the locking member is located a retracted position where the locking member contacts a surface of the sheet and allows the sheet to pass; and a second urging portion configured to urge the locking member to a position where the abutment surface abuts a succeeding sheet.

A station for picking up and delivering shaped sheets that define box-like bodies of different types includes a magazine for the sheets and at least one handling element for at least one sheet at a time. The magazine accommodates a plurality of mutually aligned and juxtaposed sheets and the at least one handling element includes an end bracket provided with at least one grip element and at least one assembly with arms which are articulated with respect to the bracket and are independently movable with respect to a fixed frame. The bracket can move between a first configuration of alignment with the end sheet accommodated in the magazine, in the condition where the at least one grip element is in contact with the end sheet, and a second configuration of alignment with a conveyance line of the sheets which corresponds to the delivery region.

Disclosed is a corrugated paperboard box making machine which comprises a feeding control mode setting unit for setting a feeding control mode to one of a first feeding control mode for controlling a sheet feeding apparatus and a second feeding control mode for controlling the sheet feeding apparatus such that the sheet feeding operation is performed plural times during the period of time in which the printing rotor is rotated 360 degrees, and a control apparatus for controlling the sheet feeding apparatus according to the set feeding control mode. The control apparatus is operable to execute a sheet feeding stop control processing of, when the second feeding control mode is set, controlling the sheet feeding apparatus such that the sheet feeding operation is stopped at least once after execution of the sheet feeding control processing.

A sheet processing apparatus includes: a pair of binding members that respectively have a pair of crimping teeth facing each other, which move between binding positions where a sheet bundle is bound and retreat positions retreated from the binding positions; and a pair of regulating members that are arranged close to the binding members and respectively have a pair of regulating pieces which face each other and move between regulating positions where displacement of the sheet bundle bound by the pair of crimping teeth is regulated and retreat positions retreated from the regulating positions, wherein a separation distance between the pair of regulating pieces at the retreat positions of the regulating pieces is longer than a separation distance between the pair of crimping teeth at the retreat positions of the crimping teeth.

A sheet detecting apparatus has an abutment member against which a leading edge of a conveyed sheet abuts, a holding member with a positioning portion to hold the abutment member, and an indicator flag moving in association with movement of the abutment member. The abutment member moves between an abutment position and a retracted position, the holding member moves between a first position and a second position retracted from the first position, the abutment member is pushed by the leading edge of the sheet when the holding member is at the first position, with the push moving the holding member to the second position, the holding member is moved in a direction away from the first position so that the leading edge of the sheet is separated from the abutment surface, and the holding member moves from the second position to the first position when the abutment member is pushed by the sheet to the retracted position.
