A diverting system is proposed for diverting boxes from normal production flow. One embodiment comprises a diverter with a diverter surface, a diverter cam in contact with the diverter, a diverter cam shaft connected to the top diverter cam such that rotation of the diverter cam shaft causes rotation of the diverter cam, and an electric motor connected to the diverter cam shaft and configured to rotate the diverter cam shaft. The diverter cam is configured to control position of the diverter as the diverter cam rotates such that rotation of the diverter cam causes the diverter surface to move from a position above normal production flow to a diverting position within the normal production flow.

A paper reversing apparatus includes a main conveyance path, a reversing path, first and second guiding plates and a hardware processor. The reversing path is disposed so as to form a predetermined angle with respect to the main conveyance path. Paper enters the reversing path from the main conveyance path and leaves the reversing path to the main conveyance path by being sent backward. When paper enters the reversing path, the processor moves the first guiding plate to a position for the paper to follow the first guiding plate and moves the second guiding plate to a position to avoid the paper. When paper leaves the reversing path, the processor moves the second guiding plate to a position for the paper to follow the second guiding plate and moves the first guiding plate to a position to avoid the paper.

It is an object of the present invention to provide method for receiving sheets for a sheet supplying apparatus. The method includes converting an up and down motion of a tray to a rotational motion of a rotary member by a movement conversion mechanism, converting the rotational motion of the rotary member around a rotational axis to a linear motion of a cylindrical member parallel to the rotational axis by the rotary member and a cam and slider mechanism, and elastically pressing an end portion of the cylindrical member of the cam and slider mechanism in the rotational axis direction to lift the tray by a compression spring.

An example system includes a pressure plate actuating portion. The pressure plate actuating portion includes a cam gear coupled to a cam arm and a pressure plate arranged to be driven by the cam arm as the cam arm rotates with the cam gear through a pick-up cycle, the pressure plate being biased in a first direction toward the cam arm with a pressure plate spring. The example system also includes a pressure plate release control portion, the pressure plate release control portion being arranged to transfer potential energy from the pressure plate spring in a gradual manner.

A sheet feeding apparatus includes an abutment part having an abutment area against which a leading edge of a sheet abuts and a moving part to move the abutment part between first and second positions. The moving part includes a link member having an engage portion to engage with a positioning portion, the link member being joined with the abutment part, and an urging member to urge the link member such that the abutment part moves toward the second position. The abutment part is retained at the first position against an urging force of the urging member in a case where the positioning portion is engaged with the engage portion of the link member.

A sheet conveyance apparatus includes a cover unit, a base unit, a roller unit configured to be detachable from the cover unit, and comprising a roller configured to convey the sheet along a conveyance path and a holder comprising an arm portion configured to extend in a width direction orthogonal to a sheet conveyance direction, a cam configured to swing the holder by rotating, and a cover member configured to be openable and closable with respect to the cover unit and configured to cover at least a portion of the arm portion against the conveyance path in a closed state, the cover member being opened by being pressed by the arm portion in a case where the roller unit is detached from the cover unit.

A sheet supplying apparatus includes a cam gear to rotate about a first axis of rotation between first and second rotating positions, and an alignment member rotatable to an alignment position to block a fore-end of a sheet of a printing medium contained on a loading table, and a transport-allowing position to allow a sheet picked up by a pickup member to be transported, according to the rotating position of the cam gear. The sheet supplying apparatus includes a main gear to rotate about a second axis of rotation, a swing arm rotatable about the second axis of rotation, and first and second swing gears, supported by the swing arm, to selectively contact the cam gear according to a rotating direction of the main gear so as to rotate the cam gear between the first and second rotating positions.

A sheet conveying device includes a sheet tray on which one or more sheets are placed, a pickup roller by which a sheet is picked up from the sheet tray, and an elevating mechanism. The elevating mechanism includes a shaft rotated by a motor, and a cam attached to the shaft and rotated together with the shaft to raise and lower the sheet tray with respect to the pickup roller. The sheet conveying device further includes a load applying mechanism contacting the shaft to apply a load thereto.

A perforation device includes a shaft, a perforation motor, at least a first perforation portion, at least a second perforation portion, at least a first cam for reciprocating a first perforation blade in the first perforation portion, at least a second cam for reciprocating a second perforation blade in the second perforation portion, a rotation speed detecting portion, a home position detecting portion, and a controller. In second perforation processing in which the shaft is rotated one turn to perform first perforation with the first perforation portion and second perforation with the second perforation portion in sequence, the controller senses, with the rotation speed detecting portion, the rotation speed of the shaft after the first perforation blade penetrates the sheet in the first perforation and, based on the rotation speed detecting, the controller determines the timing of starting braking control in the second perforation and performs braking control.

A sheet supplying apparatus includes an alignment member pivotable to an alignment location for blocking and aligning fore-ends of media contained on a loading table, and a transport-allowing location for allowing a medium picked up by a pickup member to be transported, a cam gear including a gear portion partially including a tooth-omitted portion, and a cam portion for switching the alignment member between the alignment location and the transport-allowing location at first and second rotating locations, a swing arm pivotable about a same axis as a rotation axis of a main gear, and first and second swing gears supported by the swing arm to interlock with the main gear, selectively interlocking with the gear portion according to a rotating direction of the main gear, and rotating the cam gear to the first and second rotating locations.
