Sheet conveying device, image forming apparatus with sheet conveying device, and method of correcting skew of sheet by using sheet conveying device
A sheet conveying device includes a sheet skew corrector to correct a skew of a leading end of a sheet inclining from a sheet conveyance direction and a pair of registration rollers disposed upstream of the sheet skew corrector in the sheet conveyance direction. The pair of registration rollers freely contacts and separates from each other. The pair of registration rollers conveys the sheet downstream of the sheet skew corrector in the sheet conveyance direction when driven at a prescribed time. A pair of conveyance rollers is placed upstream of the pair of registration rollers in the sheet conveyance direction. The pair of conveyance rollers continuously sandwiches the sheet from when the sheet with the skew corrected is sandwiched by the pair of registration rollers to when a trailing end of the sheet passes between the pair of conveyance rollers.
DESKEWING MEDIA
A deskew module of a valuable media depository is selectively controlled to operate in two deskew modes of operation. One deskew mode of operation selectively activates a single angle drive idler in a first cell while simultaneously activating a single straight drive idler in second cell, which forces the media to self-align against an edge of the deskew module for exiting the deskew module deskewed.

Image forming apparatus
An image forming apparatus includes a casing, an image forming unit movable between an accommodated position and a shifted position, an actuator, an urging member, a cam, and a contact portion. The actuator includes a pivot shaft and a protrusion protruding therefrom. The protrusion at a standby position crosses a conveyance path and is contactable with a sheet conveyed along the conveyance path. When the image forming unit is at the accommodated position, the contact portion and the cam contact each other and maintain the protrusion at the standby position against an urging force of the urging member. As the image forming unit moves from the accommodated position to the shifted position, the contact portion and the cam move away from each other such that the protrusion pivots from the standby position, by the urging force, to a retracted position at which the protrusion is retracted from the conveyance path.

Sheet conveying device, image forming apparatus including the same, and sheet conveying method
A sheet conveyance device, an image forming apparatus, and a sheet conveying method that convey a sheet in a predetermined sheet conveyance direction make a surface moving speed of a driven roller higher than a surface moving speed of a drive roller when a rotational driving force from the drive roller is transmitted to the driven roller, and by a one-way clutch that is provided at any place in a drive transmission path from the drive roller to the driven roller, restrict relative rotation of the driven roller in a first rotation direction, which is the sheet conveyance direction, with respect to the drive roller while allowing relative rotation of the driven roller in a second rotation direction, which is a direction opposite to the first rotation direction, with respect to the drive roller.

Printing sheet brake
A device for decelerating a transported and flat shaped product includes a brake operable by an air jet supplied by an air jet nozzle. The air jet nozzle is configured to impinge the air jet on a braking force implementing body to exert a braking force on the flat shaped product. The braking force implementing body includes: at least one first element, which has a physical structure for a return-flow of the air jet supplied by the air jet nozzle, and at least one second element, which for the braking force implementation is in an operative connection with the first element. The second element is configured to implement an impulse force caused by the air jet from the air jet nozzle. The impulse force results as the braking force onto the flat shaped product.
