  • Patent number: 7907886
    Abstract: An image forming apparatus comprising: a main body having an image forming section; a sheet feed section having a sheet cassette that accommodates a recording sheet and can be drawn out and loaded to the main body; and a sheet misalignment preventing mechanism that intermittently comes into contact with an uppermost recording sheet in the sheet cassette so as to prevent misalignment of the recording sheet in a loading direction when the sheet cassette drawn out of the main body is reloaded.

  • Patent number: 7891655
    Abstract: A method for moving a first combination of media from a media stack including one or more combinations of media. The first combination of media is an uppermost combination of media in the media stack. The method includes gripping the first combination of media and bending along a first axis by moving a first portion away from the media stack. The first combination of media is bent along a second axis by moving a flexing member while in contact with a second portion of the first combination of media, wherein the second axis is not parallel to the first axis. The first combination of media is repeatedly bent along the second axis while pausing movement of the first combination of media between the first bending along the second axis and the second bending along the second axis.

  • Patent number: 7420693
    Abstract: A paper cartridge of a printer including a cartridge body to load papers to be picked up, and a friction plate to provide a predetermined friction force to a front end of the papers picked up at the cartridge body. The friction plate is sloped at a predetermined angle in the body so that the friction plate can be moved by being pushed by the front end of the paper.

  • Patent number: 7004461
    Abstract: In a device for isolating and feeding the lowest sheet (1) in each case from a stack (2), with pushing-out elements (9) which grip the rear edge (3a, 3b) of the sheet (1) and transport it through, under a front-edge stop (5), into a pair of drawing-off rollers (6), can be moved forwards and backwards, are mounted on a cross-member (7) and have faces (9a), which are optionally front-mounted, for supporting the rear region of the stack (2) and also have bearing elements (11, 12) supporting the stack (2), and lateral abutment strips (13), the front edge (4) of the said stack being constant with respect to the sheet length (H), provision is made, in order to achieve high isolating outputs and faultless feeding of the sheets (1) with a device of simple design, for the cross-member (7) which receives the pushing-out elements (9) to be guided so as to be capable of travel in a linear guide (14), and for there to be directly associated with the said cross-member (7), for the driving movement of the latter, a linear m

  • Patent number: 6969062
    Abstract: A guide apparatus for guiding sheets to a sheet-processing machine, in particular a printing machine, and a method of operating the guide apparatus are described. The guide apparatus has at least one guide element which is disposed above a feed table and whose distance from the feed table can be set with the aid of a height-adjusting device. The guide apparatus is distinguished by the fact that the height-adjusting device has a first drive and a second drive, which can be actuated independently of each other.

  • Patent number: 5123887
    Abstract: An apparauts for placing a printer-slotter in positions where it processes sheets of corrugated paper. The printer-slotter includes a feeding unit for feeding the sheets, processing units, and differentials connected with the processing units. The apparatus comprises a position detector for detecting the position of the kicker of the feeding unit, positioning controllers connected with a central control unit (CCU), and sensors detecting the angular positions of the rotating cylinders included in the printing units and in the creaser-and-slotter unit. The sensors are connected with the positioning controllers, respectively. The CCU compares the position of the kicker with the positions at which the processing units process the sheets. The CCU controls the differentials in such a way that the position of the kicker corresponds to the positions at which the processing units process the sheets.

  • Patent number: 4735713
    Abstract: A dispenser is provided to dispense laminations to a forward position whereat they may readily be manually grasped for withdrawal from a dispenser and insertion into a preformed coil. One or more laminations may be dispensed in a selected group of laminations so that this entire selected group may be withdrawn at one time and need not be separately manipulated to align those laminations before they can be inserted into the coil. When the laminations are withdrawn from the forward dispensing position, a proximity sensor senses the absence of such laminations and controls an actuator to transversely move laminations from the bottom of the stack of laminations in the dispenser to the forward position, ready to be withdrawn by the operator, and then the actuator withdraws to the rearward position. Abutment means are axially adjustable to select one, two or more laminations in the selected group of laminations being dispensed to the forward position.
