Abstract: A sheet feed apparatus includes a sheet separation unit, and the sheet separation unit includes a separation roller that is provided so as to be brought into contact to an outer peripheral surface of a sheet feed roller, and separates a sheet fed by the sheet feed roller into one. The sheet separation unit comprises a hook for rotatably supporting the sheet separation unit in a main body casing of the sheet feed apparatus and an engaging claw that makes the sheet separation unit engage with the main body casing. Therefore, the sheet separation unit is held in the main body casing detachably.

Abstract: A sheet conveyance device includes a pair of separable contact rollers configured to convey a sheet, a contact/separation mechanism configured to support the pair of separable contact rollers in such a manner that the pair of separable contact rollers are able to come into separable contact with each other, and a solenoid configured to operate the contact/separation mechanism. The solenoid is driven so that the contact/separation mechanism causes the pair of separable contact rollers to come into pressure contact with each other, and driving of the solenoid is cancelled so that the contact/separation mechanism causes the pair of separable contact rollers to be separated from each other. Pulse width modulation duty control is performed on the solenoid while the pair of separable contact rollers are in pressure contact with each other when a plurality of the sheets are conveyed one by one at an interval.

Abstract: A sheet transporting device in which a curved transport path is provided downstream in a sheet transport direction from a merging section where a plurality of transport paths, which are formed by transport guides for transporting sheets, merge, is provided. The sheet transporting device includes a sheet guide member that extends towards the curved transport path from the merging section, with an extending end portion of the sheet guide member being disposed so as not to contact the transport guides. The sheet guide member reduces jumping up of a trailing end portion of a sheet caused by flexing of the sheet passing through the merging section towards the curved transport path.
