A sheet accommodating apparatus includes a loading portion onto which a sheet is loaded, a lifting and lowering unit that lifts and lowers the loading portion, a raising portion that raises a sheet loading surface with respect to a lowermost lowering position of the loading portion and above which a portion of the sheet is loaded, and an extension portion that extends to a position outward of the loading portion from the raising portion side as seen in plan view and supports another portion of the sheet.

A sheet stacking apparatus includes: a sheet stacker capable of stacking a sheet; a sheet conveyer that conveys the sheet to the sheet stacker; an openable member that can be opened/closed at time of taking out the sheet stacked on the sheet stacker; and a hardware processor that controls the sheet conveyer so as to convey the sheet to the sheet stacker in a case where an opened/closed state of the openable member is an intermediate state between a fully-opened state and a fully-closed state.

The application relates to a media drawer for a media processing device with a housing and an electrically-driven lift table arranged in the housing, where the media drawer is movable between a first position, in which the media drawer is arranged in the media processing device in such a manner that media can be removed from the media drawer by the media processing device, and a second position, in which media can be inserted into the media drawer, where the lift table can be supplied with power in the first position by the power supply of the media processing device. Further, the media drawer can exhibit a power supply that is independent of the power supply of the media processing device, via which the lift table can be provided with power in the second position.

A suction fan of a sheet feeder sucks in air through a sheet feeding belt to generate flotation air. The suction fan uses the flotation air to attract set sheets by suction. A belt motor rotates a sheet feeding belt and feeds out a sheet of the set sheets. An interval measurer measures a sheet-to-sheet interval when the suction fan is attracting the sheet by suction. Based on an output of the interval measurer, a controller recognizes the sheet-to-sheet interval. Based on the recognized sheet-to-sheet interval, the controller adjusts a flow rate of the flotation air.

A sheet feeding apparatus includes a sheet loader, a rear end holder, an air blower, a front end holder, a sender and an air controller. The sheet loader stores stacked sheets. The rear end holder holds a rear end of a topmost sheet on the sheet loader. The air blower blows air to the loaded sheets to raise a sheet. The front end holder holds a front end of the raised topmost sheet. The sender sends the sheet in the sheet feeding direction. The air controller controls the air blower to start blowing a raising air to raise the sheet after the rear end holder holds the rear end of a next sheet that is stacked under the topmost sheet before a rear end of the topmost sheet sent in the sheet feeding direction by the sender passes through the front end holder.

A paper feed apparatus in accordance with the present invention feeds printing paper stored in a printing paper storage unit. The printing paper storage unit includes: a paper stacking table on which the printing paper is stacked; and an erected member erected along a side of the paper stacking table. The erected member includes a low erected portion formed lower in a height direction than a surrounding portion of the erected member. The paper stacking table has a top face thereof located at a position as high as, or higher than, the low erected portion in the height direction.

A sheet feeding device includes a sheet stacker configured to stack a sheet bundle; a blower configured to float a sheet on an upper portion of the sheet bundle; a conveyor configured to convey the sheet floated by the blower; a lift configured to lift up and down the sheet stacker; a first reflective optical sensor configured to detect the sheet floated by the blower; a second reflective optical sensor configured to detect the sheet bundle and a side face of the sheet stacker, the side face including a detection region to be detected by the second reflective optical sensor and a non-detection region not to be detected by the second reflective optical sensor; and circuitry configured to control the lift based on a detection result of the first reflective optical sensor and a detection result of the second reflective optical sensor. The circuitry is configured to cause the lift to lift up the sheet stacker in response to a change from a detection state to a non-detection state of the second reflective optical sensor.

An image forming system includes: an image former that forms an image; a stacker that stacks a recording medium on which an image has been formed by the image former and which has been discharged from the image former; a lifter that raises or lowers the stacker between a stacking position where the recording medium is stacked and a lower position located below the stacking position; a recording medium detector that detects the recording medium stacked on the stacker; and a hardware processor that controls driving of the lifter so as to lower the stacker from the stacking position to the lower position when it is determined that the recording medium is on the stacker on the basis of a detection result of the recording medium detector within start-up time from a time when power is switched on to a time of shifting to an image formable state.

A paper stacking apparatus according to an embodiment of the present disclosure includes a stacking table, a first sensor, and a hardware processor. The stacking table includes an upper face on which papers are stacked, the stacking table being capable of being elevated and lowered by a drive mechanism. The first sensor is disposed at a first position and configured to detect the upper face of the stacking table or an upper face of stacked objects stacked on the stacking table. The hardware processor is coupled to the drive mechanism and the first sensor. The hardware processor is configured to determine that the stacking table is excessively elevated when an elapsed time after starting to detect the object by the first sensor is at least a first excessive-elevation determination value of time.

A paper feeding device has a paper feed tray, a device body, a fan, a rectifying member, and a retreat mechanism. A paper bundle in which a plurality of sheets of paper are stacked can be placed on the paper feed tray. The rectifying member is positioned above the paper bundle placed on the paper feed tray in a state in which the paper feed tray is accommodated in an accommodating part of the device body. The rectifying member generates a negative pressure between the rectifying member and an uppermost sheet of paper of the paper bundle using airflow from the fan in a state in which the paper feed tray is accommodated in the accommodating part. The retreat mechanism displaces the rectifying member in conjunction with the paper feed tray so that the rectifying member retreats from the paper feed tray in at least one of a pull-out operation and a push-in operation of the paper feed tray.
