摘要： 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.

摘要： 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.

摘要： A printing apparatus comprises a conveyance control unit which controls conveyance of printing sheets so that a trailing edge of a preceding sheet as a printing sheet precedingly fed from the stacking unit and a leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other; and a skew correction unit which performs skew correction of the succeeding sheet while the succeeding sheet overlaps the preceding sheet by the conveyance control unit. The skew correction unit makes the leading edge of the succeeding sheet abut against the conveyance roller during a time from an end of a last line feed operation by the conveyance roller for printing on the preceding sheet by the printing unit to start of a next conveyance operation.

摘要： 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.
