Claim Text:
1. A sheet conveying device comprising: a device main body; a first sheet feed cassette configured to feed a sheet stored therein in a sheet feed direction in which the sheet is fed to the device main body and be inserted to and pulled out from the device main body in an insertion/pulling-out direction which intersects with the sheet feed direction; a second sheet feed cassette disposed in alignment with the first sheet feed cassette on a downstream side thereof in the sheet feed direction and configured to be inserted into and pulled out independently from the device main body in the insertion/pulling-out direction; a conveyance unit disposed above the first sheet feed cassette and the second sheet feed cassette in the device main body and configured to be inserted into and pulled out independently of the first sheet feed cassette and the second sheet feed cassette in the insertion/pulling-out direction and convey a topmost sheet of the sheets stored in the first sheet feed cassette toward a sheet conveyance path that is provided more on the downstream side in the sheet conveyance direction than the second sheet feed cassette; a feed roller provided in the conveyance unit in such a way as to be displaced above the sheets stored in the first sheet feed cassette and feed the topmost sheet to the conveyance unit; a lift plate having a sheet stacking surface on which the sheets stored in the first sheet feed cassette are placed, and configured to be raised and lowered between an upper position and a lower position, wherein when the lift plate is at the upper position, the sheets on the lift plate abut on the feed roller and the feed roller is allowed to feed the sheet, and when the lift plate is at the lower position, the sheets on the lift plate are separated from the feed roller; a lifting portion configured to raise and lower the lift plate between the upper position and the lower position; an interruption portion projecting from an upper part of the first sheet feed cassette; and an actuator member provided in the conveyance unit and configured to be displaced between a first position and a second position in conjunction with displacement of the feed roller, wherein the actuator member at the first position is allowed to contact the interruption portion, and the actuator member at the second position is separated from the interruption portion, wherein the conveyance unit is configured such that when the conveyance unit is pulled out in a state where the actuator member is at the first position, the actuator member and the interruption portion contact each other, and the conveyance unit is pulled out together with the first sheet feed cassette, and when the conveyance unit is pulled out in a state where the actuator member is at the second position, the actuator member does not contact the interruption portion, and the conveyance unit is pulled out independently of the first sheet feed cassette.
