A medium transport apparatus includes: a frame; a table including a placement surface on which a medium is placed, a first end portion, and a second end portion, the table extending from the first end portion to the second end portion and being rotatable about a first shaft portion parallel to the placement surface; a first rotor arranged adjacent to the first end portion of the table; a second rotor arranged adjacent to the second end portion of the table; a belt that is stretched by the first rotor and the second rotor, and is configured to rotate circularly and to transport the medium in a first direction from the first end portion toward the second end portion; and a biasing part that links the frame and an attachment part provided between the second end portion and the first end portion of the table, and that biases the table.

A cart chassis is described which includes: multiple areas inside the chassis to accommodate either of two different types of modular accessory trays in multiple configurations. An upper platform of the chassis is to support a print engine.

Provided is a stacker including a stacking shelf on which printed paper from a printer is received and stacked, a lifting and lowering mechanism that lifts and lowers the stacking shelf, and a stacker control unit that controls the lifting and lowering mechanism. The stacker control unit controls the lifting and lowering mechanism to lift and lower the stacking shelf to a first predetermined height corresponding to the printer at a receiving position for receiving the paper from the printer, and to lift and lower the stacking shelf to a second predetermined height corresponding to a sheet processing machine at a paper supply position for supplying paper to the sheet processing machine, the paper supply position being different from the receiving position.

An image forming apparatus to which a first feeding device which does not notify abnormal sheet feeding or a second feeding device which notifies the abnormal sheet feeding is connectable includes a sheet receiving portion, a sheet detector, an image forming unit, and a controller. In a case that the first feeding device is connected to the image forming apparatus, the controller discriminates that the abnormal sheet feeding occurs in the first feeding device when the detector does not detect the sheet at first timing. In a case that the second feeding device is connected to the image forming apparatus, the controller discriminates that the abnormal sheet feeding occurs at the sheet receiving portion when the detector does not detect the sheet at second timing and notification of the abnormal sheet feeding is not provided from the second feeding device.

The invention provides a sheet storage apparatus and a printing apparatus, which include simplified mechanisms for supporting a sheet and for guiding the sheet. A sheet storage device that can store a sheet discharged from a discharge port of a printing apparatus includes: multiple flappers provided below the discharge port and arranged in a width direction of the sheet, each flapper being rotatable between a first posture in which the sheet discharged from the discharge port is guided downward in a gravitational direction by using a first surface, and a second posture in which the sheet is supported by using a second surface being different from the first surface; and a connecting unit which connects the plurality of flappers to one another.

An opening radial dimension is set as a radial direction permissible dimension K of the metal coil as expressed by the following equation or lower. $K=\frac{\mathrm{Yp}Z}{2\mathrm{EI}}{R}^2\left(-\sin \cos \right)$ Wherein: K is a radial direction permissible dimension at the load action point position in mm; Yp is a yield stress of the metal sheet, in kgf/mm.sup.2; Z is a section modulus of the metal sheet, in mm.sup.3; R=(a metal coil radius r)(the plate thickness t of the metal sheet), in mm; E is a Young's modulus of the metal sheet, in kgf/mm.sup.2; I is a second moment of area of the metal sheet in mm.sup.4; and is an angle in radians about the axis of the metal coil from the load action point to the nearest restraining roll along a rewind direction of the metal coil.

A device for removing road tape from a surface comprises a body, and a drive assembly coupled to the body. The drive assembly comprises a motor having a drive wheel, at least one drive belt, a rolling drum drive wheel configured to engage the at least one drive belt, and at least one rolling drum configured to secure an end of the road tape. The rolling drum is configured to rotate in response to rotation of the rolling drum drive wheel and wind the road tape about a circumference. The winding of the road tape drives the body in a forward direction.

A sheet storage apparatus according to an embodiment of the present invention includes a receiving unit which receives a sheet that is discharged from a discharge port at a position below the discharge port, and a sheet butting unit which is provided in the vicinity of the receiving unit and receives a front end portion of the sheet. The sheet butting unit has a projection which is provided on at least one of an inner side surface and an inner upper surface of the sheet butting unit. The projection is configured to be capable of retaining a state of regulating vertically upward movement of the front end portion of the sheet being discharged from the discharge port.

The invention provides a printing apparatus and a sheet storage device which 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 sheet 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 state 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 medium transport apparatus includes: a frame; a table including a placement surface on which a medium is placed, a first end portion, and a second end portion, the table extending from the first end portion to the second end portion and being rotatable about a first shaft portion parallel to the placement surface; a first rotor arranged adjacent to the first end portion of the table; a second rotor arranged adjacent to the second end portion of the table; a belt that is stretched by the first rotor and the second rotor, and is configured to rotate circularly and to transport the medium in a first direction from the first end portion toward the second end portion; and a biasing part that links the frame and an attachment part provided between the second end portion and the first end portion of the table, and that biases the table.
