摘要： A document feeder includes a document placing portion, a pick-up roller, a pair of feed rollers, a pair of registration rollers, a document sensor, a moving mechanism, and a control portion. The pick-up roller can move between a sheet feeding position where the pick-up roller contacts with the upper surface of the document placed on a placement surface and a standby position where the pick-up roller does not contact with the upper surface of the document placed on the placement surface. The document sensor detects a document between the feed rollers and the registration rollers in a document feed direction. The moving mechanism moves the pick-up roller up and down. The control portion moves the pick-up roller up to the standby position at a timing when the leading edge of the card document reaches the document sensor in a card document mode in which card documents are successively fed.

摘要： A drive transmission mechanism of a sheet transportation apparatus of the present invention comprises an upstream transportation roller gear and a planet gear for transmitting a first driving force from a driving source to the upstream transportation roller gear, and a release mechanism for preventing the upstream transportation roller gear and the planet gear from engaging with each other. The release mechanism prevents the engagement of the planet gear and the upstream transportation roller gear when the driven gear is driven to reversely rotate by a second driving force. The release mechanism prevents the engagement by moving a release member before the planet gear and the driven gear engage with each other. The release mechanism moves the release member by the driven gear being reversely rotated by the second driving force which is a driving force other than the driving source. This makes it possible to realize a drive transmission mechanism of a sheet transportation apparatus comprising a release mechanism capable of releasing the engagement of the driven gear and the drive gear for transmitting the driving force from the driving source to the driven gear, without the need of reversely rotating the driving source or the fear of impairing the driving force from the driving source.

摘要： When a first elapse time Δt3 from time point t1 of stop of a transport motor reaches a first specified time S1, a registration roller electromagnetic clutch is engaged. At time point t2 at which the first elapse time Δt3 reaches 50 ms, normal rotation of the transport motor is started. At time point t3 at which a second elapse time Δt4 from the time point t2 reaches a second specified time S2 (a given length of time), a reverse roller electromagnetic clutch is switched from an engaged state to a disengaged state, rendering reverse rollers and sheet discharge rollers freely rotatable. At subsequent time point t4, a coil of a solenoid is de-energized, to separate the reverse rollers from each other.

摘要： A hinge mechanism of an image forming apparatus supporting a platen cover for holding an original at a fixed position on a platen glass includes a hinge unit for supporting the platen cover in such a manner that the platen cover can be opened and closed by swinging it up and down, a compression coil spring for biasing the platen cover in its opening direction, and a hinge holder attached to a housing of the apparatus for accommodating the compression coil spring. The hinge unit is provided with a hinge torque keeping mechanism which causes the compression coil spring to produce a specific amount of hinge torque to bias the platen cover in its opening direction even when the platen cover is closed.

摘要： An original reading device includes a registration roller located upstream of an original reading position in an original transport path for adjusting the timing of feeding an original to the original reading position. There is at least one original feed roller for transporting the original which has been fed from an original loading tray into the original transport path toward the registration roller. A rotary motion controller is also provided, and it causes the original feed roller closest to the registration roller to rotate when a rear part of the original close to a trailing edge thereof passes over the original feed roller closest to the registration roller.
