Abstract: A printing unit performing printing by applying ink to a print medium conveyed in a first direction, a reversal conveyance path reversing the print medium conveyed in a second direction opposite to the first direction to guide the print medium to a position to which the ink can be applied by the printing unit, and a control unit performing printing on a first side and an opposite second side in a first print medium and a subsequent second print medium are included, and in starting printing on the first side in accordance with the amount of the ink applied to a region that the second print medium being conveyed in the first direction contacts in the first print medium conveyed through the reversal conveyance path after the first side is printed, the control unit keeps the second print medium on standby for predetermined time in the first position.

Abstract: A printing apparatus includes a printing unit, and first, second, and third conveyance paths. The printing unit performs printing at a printing position on a print medium conveyed in a conveyance direction. The first conveyance path causes the print medium to pass through the printing position of the printing unit. The second conveyance path reverses obverse and reverse surfaces of the print medium, and the third conveyance path reverses obverse and reverse surfaces of the print medium. The second conveyance path branches from the first conveyance path at a first branching point on a downstream side of the printing position in the conveyance direction and merges into the first conveyance path on an upstream side of the printing position. The third conveyance path branches from a second branching point on the second conveyance path and merges into the first conveyance path on the upstream side of the printing position.

Abstract: A printing apparatus includes a supply unit, a supply path, first and second conveyance paths, a printing unit, and an inversion roller. The first conveyance path conveys, to a first direction, a print medium. The printing unit prints an image on the two surface of the print medium. The inversion roller inverts a conveyance direction of the print medium and conveys the print medium in a second direction. The second conveyance path conveys the print medium conveyed in the second direction to the first conveyance path while inverting the print medium. When performing printing on both sides of print media, the print media are convey such that a first print medium supplied from the second conveyance path and a second print medium supplied from the supply path overlap in the first conveyance path.

Abstract: A printing apparatus includes a first conveyance path, a conveyance roller, a printing unit, a reverse roller provided at a position on a downstream side of the printing unit in a first direction, a second conveyance path configured to reverse the front and back of the print medium, and a control unit. In a case where a first print medium on which printing has been performed first is conveyed in a second direction via the second conveyance path, the control unit controls the conveyance roller and the reverse roller, such that a trailing edge of the first print medium in the second direction passes through the reverse roller before a second print medium conveyed by the conveyance roller subsequent to the first print medium reaches the reverse roller.

Abstract: A recording apparatus to record an image on a sheet includes a roller pair and a switching unit. The roller pair sandwiches the sheet between the roller pair to convey the sheet. The switching unit switches between a first state in which the roller pair sandwiches the sheet and a second state in which rollers of the roller pair are separated from each other. The switching unit includes a first movable member that is moved in a first direction so that the first state is switched to the second state, and includes a second movable member that is moved in a second direction different from the first direction so that the first state is switched to the second state.

Abstract: An object of the present invention is to provide a printing apparatus including a scanner unit openable and closable with respect to a printer body unit for simultaneously achieving smooth opening/closing movement and the downsizing of the apparatus. The printing apparatus includes a first gear member provided in the printer body unit and a second gear member which is attached to the scanner unit so as to be swingable with respect to the scanner unit and which is in mesh with the first gear member. When the scanner unit opens or closes with respect to the printer body unit, the second gear member swings with respect to the scanner unit while retaining a meshing state with the first gear member.

Abstract: There is provided an image forming apparatus including a scanner unit configured to be openable on an apparatus front side with respect to a printer unit due to a first hinge portion on an apparatus rear side, a cover to cover a feed port configured to be openable due to a second hinge portion on the apparatus front side of the feed port, wherein a rotation axis of the first hinge portion is positioned on the apparatus rear side of a rotation axis of the second hinge portion in an apparatus depth direction. Interlocking with an operation to open the scanner unit, the cover moves while a portion thereof is in contact with a surface of the paper feed tray or the sheet placed thereon to open the cover in an interlocking manner.

Abstract: A carriage device includes a first guide member and a second guide member for supporting a carriage with a head mounted thereon at two separate positions and guiding reciprocation of the carriage, a first adjustment unit configured to adjust a height of the carriage relative to the first guide member through movement of the carriage, and a second adjustment unit configured to adjust a height of the carriage relative to the second guide member through the movement of the carriage. The carriage device can sequentially perform a first operation of changing the height of the carriage by the first adjustment unit and a second operation of changing the height of the carriage by the second adjustment unit.

Abstract: An interval switching member that relatively displaces a carriage with respect to a printing medium in a direction orthogonal to a printing surface of the printing medium is provided between the carriage and a first guide member, and between the carriage and a second guide member. Subsequently, an inclination control member that changes a distance between the carriage and the first guide member is provided between the carriage and the first guide member. By changing the distance between the carriage and the first guide member with the inclination control member, the carriage rotates about a second guide rail serving as a central axis, such that an angle of the printing head against the printing medium is changed.

Abstract: An image reading and recording apparatus includes an image recording unit and an image reading unit supported to be pivotally movable above the image recording unit and configured to be opened and closed by being pivotally moved relative to the image recording unit. The apparatus includes a stay including an opening portion formed thereon, a rotor inserted in the opening portion of the stay, a first cam surface provided on an inner peripheral portion of the opening portion, and a second cam surface provided on an outer peripheral portion of the rotor. The rotor rotates due to abutment of the first cam surface and the second cam surface with each other. The image reading unit is held in a first opened state with a first open angle, due to meshed engagement of the first cam surface and the second cam surface with each other.

Abstract: A printing apparatus includes a conveyance roller conveying a print medium, a printhead printing an image on the print medium, a carriage supporting the printhead and movable in a direction parallel to an axial direction of the conveyance roller, and a detecting unit detecting a rotation amount of the conveyance roller.
