  • Patent number: 11124000
    Abstract: A slide member slides in conjunction with reciprocation of a carriage. The slide member slides between a first position and a second position to cause a switch gear to move between a plurality of slide positions at which the switch gear engages respective ones of a plurality of transmission gears. The slide member at the second position is closer to a first end of a shaft than the slide member at the first position is. A first cover covers a first sliding contact portion of the shaft over an entire range of the first sliding contact portion in a main scanning direction. The slide member is in sliding contact with the first sliding contact portion when the slide member slides between the first position and the second position. The first sliding contact portion is closer to the first end than the slide member located at the first position is.

  • Patent number: 10183492
    Abstract: A detachable body for a printing apparatus enables positioning a board for electrical connection to a printing apparatus, while also reducing manufacturing cost. The detachable body for a printing apparatus includes a case that is mounted to and detached from a printing apparatus that performs printing on a sheet, and a board that is attached to an attachment surface that is a surface of the case, and that is electrically connected to the printing apparatus by coming into contact with detachable body-side contacts provided on the printing apparatus when the case is mounted to the printing apparatus. The attachment surface of the case is provided with an attaching portion to which the board is attached. The attaching portion surrounds the board and positions the board in a direction along the attachment surface of the case by coming into contact with peripheral edges of the board.

  • Patent number: 10144213
    Abstract: A printing apparatus includes a liquid discharge device, a carriage, and a controller. The liquid discharge device includes a first nozzle row to discharge a first liquid to form an image and a second nozzle row to discharge a second liquid of a type different from the first liquid. The carriage is mounted with the liquid discharge device and reciprocally movable in a main scanning direction. The controller is configured to control the liquid discharge device to discharge the second liquid onto a region of a medium including another region onto which the first liquid is discharged. The controller includes a control unit to control the liquid discharge device to discharge the second liquid from the second nozzle row in both of forward movement and backward movement of the carriage and discharge the first liquid from the first nozzle row in one of the forward movement and the backward movement.

  • Patent number: 10124364
    Abstract: The present disclosure relates to a manufacturing device and a manufacturing method of OLEDs. The manufacturing device includes a sprayer and a moving unit. The sprayer is arranged above a substrate, and the sprayer includes at least one nozzle configured to ejected ink on a surface of the substrate. The moving unit is configured to control the sprayer to relatively move with respect to the substrate. During an ejecting process of the ink, an ejecting speed of the ink injected by the nozzle includes a first speed weight along a horizontal direction with respect to the surface of the substrate, and a relative moving speed between the sprayer and the substrate comprises a second speed weight along the horizontal direction. The first speed weight is opposite to the second speed weight. As such, the ink may fall within a designated area so as to overcome the ink-jet printing error.
