摘要： A sheet feeding apparatus includes a sheet storage portion, a sheet supporting member that is liftable, and a damper mechanism including a resistance member and a movable portion movable by abutting against a body of the apparatus. The damper mechanism resists, at least temporarily, relative movement of the movable portion and the sheet storage portion by applying resistive force produced by the resistance member to the movable portion in a case where the sheet storage portion is inserted to the body, and resists, at least temporarily, lowering movement of the sheet supporting member by applying resistive force produced by the resistance member to the sheet supporting portion in a case where the sheet storage portion with the sheet supporting member having been lifted by the lift portion is drawn out of the body.

摘要： A translatable media height sensor assembly for measuring a media stack in an imaging forming device. The assembly includes a support and drive and insertion assemblies mounted thereon. Insertion assembly includes a translatable plunger having mounted thereon a sensor and a translatable probe. At a home position, the sensor is actuated by a flag on the support placing sensor output in a first state. During measurement, drive assembly translates insertion assembly toward a media stack and the sensor output changes to a second state and a counter is started. The probe initially encounters the media stack and stops while plunger continues to translate. As the plunger reaches the media stack, the probe engages the sensor causing the sensor output to again change state and stops the counter. The insertion assembly retracts back to the home position where the flag actuates the sensor causing the sensor output to change state.

摘要： An image forming apparatus includes a body having an opening, an image forming unit, storage units that can store a sheet, and a moving unit provided in each storage unit. The moving unit moves the stored sheet and then stops it in an exposed state where the sheet is partly exposed, from the opening, to a body outside. Where a first sheet and a second sheet, stored in a storage unit different from where the first sheet is stored, contact and then are exposed to the outside, when a first sheet moving distance to the exposed state and a second sheet moving distance to the exposed state are different, the moving unit changes a first sheet movement start timing relative to that of the second sheet or changes a first sheet moving speed relative to that of the second sheet, based on moving distances of the first and second sheets.

摘要： There is provided a stacking apparatus capable of stably conveying and stacking sheets without occurrence of damage or buckling of the sheets in the structure of discharging the curled sheets one by one. In regard to each of a plurality of clamp guides which project toward stacking trays from conveyance means to guide sheets S, the projecting position varies in accordance with a size and an amount of stacked sheets Sa on the stack trays. The stacking tray comprises an inclined surface and a curved surface. An upper guide is located to face the inclined surface by a predetermined interval, and the upper guide is located not to face the curved surface or is located to face it by an interval larger than a predetermined interval.
