An image recording apparatus includes a recording unit, first and second rollers, a guide member, and a cutting unit. The recording unit performs image recording on a sheet conveyed in a conveying direction on a first conveyance path. The first roller is located further downstream than the recording unit in the first conveyance path. The second roller is located further downstream than the first roller in the first conveyance path. The guide member has a guide surface that forms a second conveyance path extending from a connection position of the first conveyance path between the first roller and the second roller. The cutting unit is located between the connection position and the second roller, cuts a sheet, and has a cutter. The guide member changes in posture between a first posture for forming the second conveyance path and a second posture for opening the second conveyance path.

A recording device includes a recording unit, a first transport path, a second transport path, a first discharge roller pair, a second discharge roller pair, a first driving motor configured to drive the first discharge driving roller, a second driving motor configured to drive the second discharge driving roller, and a movement mechanism capable of moving the second discharge roller pair between a sandwiching state where a second discharge driving roller and a second discharge driven roller sandwich a recording medium, and a separated state where the second discharge driving roller and the second discharge driven roller are separated. In a part of a period in which the recording medium is transported, the second discharge roller pair is in the separated state.

A conveying roller unit comprises a first unit, a second unit, and a lock mechanism. The first unit comprises: a roller section; and a hollow cylindrical holder section. The second unit can be removably mounted to the first unit, and comprises: a second connection section; a rod section inserted into the holder section. The lock mechanism includes: a first engagement section provided on the inner circumferential surface of the holder section; a second engagement section provided on the outer circumferential surface of the rod section; and a urging member for pressing the second unit in the direction in which the rod section comes out of the holder section. The urging member maintains the first engagement section and the second engagement section in an engaged state and restricts the position of the second unit relative to the first unit in both the circumferential direction and the rotation axis direction.

An image forming apparatus includes a controller that performs one or more times a first image forming process including performing image formation on a sheet medium, and conveying the sheet medium in a conveyance direction by rotating a first roller by a first number of rotations and rotating a second roller disposed downstream of the first roller in the conveyance direction by a second number of rotations smaller than the first number of rotations. When a count of times the first image forming process has been performed becomes a particular number of times, the controller performs a second image forming process including performing image formation on the sheet medium, and conveying the sheet medium by rotating the first roller by a third number of rotations smaller than the first number of rotations and rotating the second roller by the second number of rotations.

There is provided an image recording apparatus including: a casing; a conveyor positioned inside the casing and configured to convey a sheet in a conveying direction; a recording part positioned inside the casing and configured to record an image, with an ink, on the sheet conveyed by the conveyor; a heater positioned inside the casing, on a downstream side in the conveying direction of the recording part, and configured to heat at least one of the sheet and the ink; a reading part positioned inside the casing, on the downstream side in the conveying direction of the heater, and configured to optically read the image recorded on the sheet; and a blower positioned inside the casing and configured to generate an air current toward the reading part and toward the sheet located at a position on the downstream side in the conveying direction of the heater.

A printing apparatus includes a conveyance path including a curving part, an inversion path for inverting a medium upside down, and a control unit, and the control unit includes a first mode for conveying the long medium at a first speed when a surface that faces inside when the long medium is rolled in a roll shape and a surface that faces inside when conveyed in a curved shape through the curving part are the same, and a second mode for conveying the long medium at a second speed lower than the first speed of the first mode when the surface that faces inside when the long medium is rolled in the roll shape and the surface that faces inside when conveyed in the curved shape through the curving part are different from each other.

An image forming apparatus includes a conveyor to convey a sheet medium, a print engine to form an image on the sheet medium, a cutter to cut the sheet medium, a signal output device, and a controller. The cutter includes a first blade, a second blade, and a moving device to move at least one of the first and second blades. The controller receives, from the signal output device, a signal indicating a variation over time in a value correlated with a moving load for the at least one blade, and determines, based on the received signal, which state the sheet medium is in among a plurality of states including a first state where the sheet medium is cut normally, a second state where there is an abnormality in cutting the sheet medium, and a third state where there is a different abnormality in cutting the sheet medium.

A printing apparatus includes a first transport roller pair configured to transport a medium while nipping the medium at a first nip portion, a second transport roller pair disposed downstream of the first transport roller pair and configured to transport the medium while nipping the medium at a second nip portion, and a device disposed between the first transport roller pair and the second transport roller pair in a transport path for the medium, and configured to nip the medium at a third nip portion, wherein a nip force in the third nip portion is weaker than a nip force in the first nip portion, and in a state where the medium is nipped at the first nip portion, a leading end of the medium is aligned with the second nip portion, and then the nipping at the first nip portion is released.
