    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: In the context of a structure wherein outer casing(s) is/are disposed so as to permit opening and closing about shaft(s), stopper member(s) and engagement piece(s) engaging with such stopper member(s) being disposed at such outer casing(s) so as to permit independent displacement in pivoting fashion about shaft(s) for each thereof, one end(s) of arm member(s) is/are supported by outer casing(s) so as to permit displacement in pivoting fashion, and shaft(s) of stopper member(s) is/are secured to other end(s) of such arm member(s). In addition, when bottom region(s) of stopper member(s) in engaged state(s) with engagement piece(s) abuts or abut and is/are pressed upward by original(s) loaded in original tray(s) during closing of outer casing(s) which had at least immediately prior thereto been in open state(s), this causes other end(s) of arm member(s) to be displaced upward in pivoting fashion, in accompaniment to which stopper member(s) is/are lifted upward.
