An image forming apparatus includes a sheet accommodating portion, an image forming portion, an accommodating portion opening portion, a lifter plate, a lifter plate lifting and lowering mechanism, a lower-limit detecting portion, a control unit lowering the lifter plate and opening the accommodating portion in accordance with an operation in a set mode of a plurality of modes when the control unit receives an instruction to open the accommodating portion, wherein the modes includes a first mode in which the accommodating portion is opened irrespective of whether or not the lifter plate lowers to the lower-limit position and a second mode in which the accommodating portion is opened after the lifter plate lowers to the lower-limit position; and an operating portion operable by an operator for changing setting of the mode, between the modes, executed when the control unit receives the instruction to open the accommodating portion.

Provided is a printing apparatus comprising: a discharging unit configured to convey and discharge print media; a tray configured to receive print media discharged in a first direction from the discharging unit; and a drive unit configured to move the tray in a second direction perpendicular to the first direction. In discharging print media, the tray is moved in the second direction to thereby receive the discharged print media at a plurality of different positions on the tray. The tray is movable to a take-out position being a position closer in the second direction to a take-out side where print media are taken out than any of the positions at which the tray receives the print media discharged from the discharging unit.

Provided is a technique that enables proper sorting of discharged print media by suppressing curling of each of the print media sufficiently. A determining unit determines a curling suppressing operation to be executed such that in a case where sorting operation is executed, the suppressing operation having a higher effect of suppressing curling is executed than in a case where the sorting operation is executed. Then, a print control unit controls a print head to perform printing on print media while executing the suppressing operation determined by the determining unit.

The paper ejection apparatus includes a housing including an ejection slot for ejecting a paper and a storage space provided below the ejection slot, a tray, formed in an arcuate shape to extend downwards and stored in the storage space to be pullable out from the storage space, for stacking the paper ejected from the ejection slot when the tray is pulled out from the storage space, and a cover swingably provided on the housing between the ejection slot and an opening of the storage space. A swinging end of the cover moves downwards by working with an operation for pulling the tray out from the storage space.

A sheet accommodating device includes a housing; a sheet accommodating portion configured to accommodate a sheet and detachably mountable in the housing, the accommodating portion including, a supporting member supporting the accommodating portion so as to be rotatable relative to the housing, a movable member movable relative to the supporting member along the supporting member, a first urging member urging the movable member in a moving direction of the supporting member, a regulating member movable in a direction crossing with the moving direction of the movable member, and a second urging member urging the regulating member so as to protrude it from the movable member. The housing is provided with an engageable member engaged with the regulating member.

The paper ejection apparatus includes a housing including an ejection slot for ejecting a paper and a storage space provided below the ejection slot, a tray, formed in an arcuate shape to extend downwards and stored in the storage space to be pullable out from the storage space, for stacking the paper ejected from the ejection slot when the tray is pulled out from the storage space, and a cover swingably provided on the housing between the ejection slot and an opening of the storage space. A swinging end of the cover moves downwards by working with an operation for pulling the tray out from the storage space.

A system for presenting media sheets includes a finisher output bin assembly. The finisher output bin assembly includes a translatable output floor, and a guide substrate coupled to the translatable output floor to guide the translatable output floor relative to the guide substrate in at least one coordinate direction. The finisher output bin assembly includes an output structure mechanically coupled to the translatable output floor to drive the translatable output floor relative to the guide substrate.

Provided is a printing apparatus that prevents a print medium from buckling during discharging, a method of controlling a printing apparatus, and a storage medium. In the case where the print conveyance speed determined by the print mode is higher than or equal to the specified speed, the print medium after printing is conveyed to the discharging tray at the print conveyance speed, and in the case where the print conveyance speed determined by the print mode lower than the specified speed, the print medium after printing is conveyed to the discharging tray at the specified speed increased from the print conveyance speed.

A tray unit assembly includes a housing, a separating/stacking unit, a tray unit and an elevating member. The separating/stacking unit includes a separating roller unit and a stacking roller unit provided in the housing. The tray unit is provided to be inserted into the housing and includes a first tray body fixed to the housing when the tray unit is inserted into the housing, and a second tray body connected to the first tray body to be slidable in a vertical direction and having a media stacking space formed therein. The elevating member is disposed to be movable up and down and configured to be in contact with a bottom surface of the second tray body to move the second tray body toward the stacking roller unit or the separating roller unit.

A medium discharge device includes: a discharge unit that discharges a medium; a first medium receiving tray that receives the medium discharged by the discharge unit; and a second medium receiving tray that is provided above the first medium receiving tray in a vertical direction and receives the medium discharged by the discharge unit. The second medium receiving tray is capable of changing a position between an advance position for receiving a medium, which is discharged, by causing at least an upstream zone of the tray including an upstream side end portion in a medium discharge direction to advance to a passing route of the medium from the discharge unit toward the first medium receiving tray and a retraction position to which the upstream zone retracts from the passing route.
