A printing apparatus and a sheet storage device meet a need for diversification in printing modes while reducing a load on a user. A printing apparatus includes a first holder which rotatably holds a roll sheet, a second holder which is located below the first holder and rotatably holds a roll sheet, a printing unit which performs printing on a shed reeled out of the first holder or the second holder, a discharge port which is provided above the first holder and discharges the sheet printed by the printing unit, and a receiving unit which is provided between the first holder and the second holder and is capable of establishing a first stab of receiving a front end portion of the sheet discharged from the discharge port and a second state of not receiving the front end portion.

A sheet housing apparatus including a housing unit, which houses a sheet to be discharged from a discharging opening of a printer, and a pair of housing-side feet disposed on both sides, in a width direction, of the sheet housing apparatus. The sheet housing apparatus can be combined with the printer. The printer includes a pair of body-side feet disposed on both sides, in the width direction, of the printer. In a state in which the sheet housing apparatus is combined with the printer, the body-side feet and the housing-side feet are arranged not to overlap with each other in the width direction.

According to an aspect of the present disclosure, a printing apparatus includes a conveyance unit configured to convey a sheet in a conveyance direction, a print head configured to perform printing on the sheet conveyed in the conveyance direction by the conveyance unit, a discharge port from which the sheet printed by the print head is discharged, a stacking portion located below the discharge port and configured to stack the sheet discharged from the discharge port in a state where a leading end of the sheet is directed to an upstream side in the conveyance direction, and a holding unit disposed in a sheet discharge path below the discharge port and configured to move between a holding position in which the holding unit holds the sheet and a releasing position in which the holding unit releases the sheet.

A sheet feed device includes: a tray provided in a device body in a manner capable of being pulled out and having a loading part that is moved up and down; an extension part attached to the device body to support a portion of a sheet to be fed through the tray; a lifting mechanism that has a lifting/lowering part for moving the loading part up and down and a driving part for lifting and holding the loading part via the lifting/lowering part; and a disconnecting part that disconnects the lifting/lowering part and the driving part when an uncoupling operation is accepted in a state in which the tray is accommodated in the device body.

A sheet container includes a housing, a stacking part provided in the housing so that recording sheets are stacked on the stacking part, a contact part to be brought into contact with edges of the recording sheets in a length direction on the stacking part in an attached state in which the contact part is attached into the housing, a connection member connected to the stacking part or the housing and having an extension part longer than the stacking part in the length direction, and a retreater that retreats the contact part in the attached state from the extension part with the connection member connected to the stacking part or the housing.

A sheet accommodating apparatus includes a main body portion, a loading portion that is provided in the main body portion and supports a portion of a sheet loaded thereon from below, a lifting unit that lifts the loading portion, and a supporting portion that is connected to the main body portion and supports another portion of the sheet from below during a process in which the loading portion is lifted.

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.

An image forming apparatus includes an image forming portion, a sheet reversing roller portion, a first sheet feeding passage, a second sheet feeding passage, a sheet a guiding member forming a retraction feeding passage for guiding upward a leading end of the sheet fed from the reversing roller portion rotating in the first direction and then for guiding the sheet, guided upward, in a direction crossing a vertical direction, the guiding member having an inner surface curved to guide one side of the sheet, and a preventing member for preventing a droop of the leading end of the sheet by contact with the sheet guided in the direction crossing the vertical direction by the sheet guiding member.

Provided are a loading portion configured to load a medium discharged from a discharging portion, and a plurality of pressing portions provided downstream of the discharging portion in a discharging direction of the medium, and configured to press the medium loaded on the loading portion. The loading portion includes a first loading portion including a downward sloped surface sloping downward in the discharging direction, and also includes a second loading portion including an upward sloped surface sloping upward in the discharging direction. The downward sloped surface and the upward sloped surface form a discharging path through which the medium is discharged. The plurality of pressing portions includes a first pressing portion configured to press the medium loaded on the first loading portion, and also includes a second pressing portion configured to press the medium loaded on the second loading portion.

An image forming system includes an image forming apparatus and a post-processing device. The image forming apparatus includes a scanner reading image data from a sheet, an image forming part forming an image on the sheet, and a sheet ejecting part ejecting the sheet after forming the image. The post-processing device includes a post-processing conveying path, and a stapling part. The post-processing conveying path introduces the sheet from the sheet ejecting part and conveys the sheet. The stapling part collects sheets conveyed on the post-processing conveying path for each predetermined number of sheets and executes staple processing to the sheets. The image forming apparatus or the post-processing device includes a size deciding part deciding a sheet size based on the image data. The post-processing device includes a staple controlling part determining a binding position for the staple processing on the basis of the sheet size.
