Abstract: The present invention provide a sheet conveying device comprising a driving source which freely rotates in a forward/reverse direction, a separation roller shaft configured to drive a separation roller to separate and feed each sheet to be conveyed in accordance with forward/reverse rotation of the driving source, a stopper unit configured to close a conveyance path of stacked sheets on an upstream side of the separation roller in a conveyance direction, a stopper opening/closing member configured to open/close the stopper unit in a vertical direction, and a transfer unit provided between the stopper opening/closing member and the separation roller shaft and configured to transfer a rotating force to the stopper opening/closing member in accordance with a drive of the separation roller shaft.

Abstract: The present invention provides a sheet conveying device comprising a first conveyance path for conveying a sheet from a pair of first rollers to a pair of second rollers, a second conveyance path for performing switchback conveyance of the sheet, a switching unit for switching the second rollers between a press-contacted state and a separated state, and a single driving source for driving the rollers and the switching unit. A non transferring of drive section is set where when the driving source switches the rotation direction after the sheet that has been switchback-conveyed has reached the first rollers, a drive from the driving source is not transferred to the second rollers. The switching unit is driven to separate the second rollers during a time the drive is not transferred to the second rollers due to the non transferring of drive section.

Abstract: A drive switching mechanism includes a transmission gear and a planetary gear configured to transmit a drive from an input gear to an output gear. The drive switching mechanism further includes a swinging member configured to hold the planetary gear such that the planetary gear can swing around the input gear, a retaining unit configured to retain the swinging member in a swing enabled or disabled state, and a releasing unit configured to disengage the planetary gear from the output gear and cause them to be spaced apart. The output gear includes a toothless part that does not engage with a gear section engaging with the transmission gear.

Abstract: An original stacking plate for supporting and stacking an original is rotatably attached to an ASF base. A fulcrum position of the original stacking plate is provided with a rotational center on the upstream side in the sheet feeding direction from a fulcrum position of a pressing plate while keeping a predetermined distance from a base surface of the ASF base. Therefore, a rotational angle of the original stacking plate in association with the vertical motion of the pressing plate when the original and recording paper have been set is smaller than that of the pressing plate.

Abstract: A sheet feeding device includes a guiding member having an upper guiding surface for guiding the upper surface of a document and a lower guiding surface for guiding the lower surface of the document to guide the document to a support portion.
