  • Patent number: 11926152
    Abstract: A printing apparatus includes a carriage mounted with a printing unit; a first motor configured to move the carriage in a predetermined direction; a second motor configured to move the carriage in the predetermined direction; and a control unit. The control unit executes a first mode in which, when causing the printing unit to perform printing under a first printing condition, the first motor is driven in a first direction and the second motor is driven in the first direction, and a second mode in which, when causing the printing unit to perform printing under a second printing condition different from the first printing condition, the first motor is driven in the first direction and the second motor is driven in the first direction while changing an output ratio between the first motor and the second motor.

  • Patent number: 11929655
    Abstract: An embodiment includes: a first transport module on which a carriage moves; a second transport module that is configured to be able to move to a position for connecting to the first transport module and on which the carriage is able to move to and from the first transport module; a position detection unit that detects a position in a moving direction of the second transport module and outputs position information; a first control unit that controls motion of the carriage on the first transport module; a second control unit that controls motion of the carriage on the second transport module; a third control unit that controls motion of the second transport module; and a fourth control unit that controls the first to third control units. The fourth control unit corrects a position where the second transport module connects to the first transport module based on the position information.

  • Patent number: 11557954
    Abstract: In a transport system that moves a moving portion, which moves in a transport direction along a fixed portion, while detecting a position of the moving portion by a scale and a sensor, a guide block is installed on a second surface of a first part of the moving portion, a guide rail is installed on a first surface of the fixed portion, the scale is installed at an end of the first part of the moving portion on an opposite side across the guide block, and a sensor that has a detecting unit at a position facing the scale is installed in the fixed portion.

  • Publication number: 20220363081
    Abstract: A printing apparatus include a carriage mounted with a printing unit, a belt, a first motor configured to drive the belt at one end in the widthwise direction, a second motor configured to drive the belt at the other end in the widthwise direction, and a control unit configured to control the first motor and the second motor. The control unit performs first control by driving the first motor in which the carriage moves from a state in which the carriage is stopped. In the first control, an output of the second motor is controlled from a first state lower than an output of the first motor to a second state higher than the first state.

  • Publication number: 20220363079
    Abstract: A printing apparatus includes a carriage mounted with a printing unit configured to perform printing on a print medium, a first motor used to move the carriage, a second motor used together with the first motor to move the carriage, and a control unit configured to control the first motor and the second motor. When moving the carriage, the control unit controls the first motor with a first control amount and controls the second motor with a second control amount. The first control amount and the second control amount are different from each other, and a ratio therebetween is a predetermined ratio.

  • Patent number: 10951092
    Abstract: A carriage on which a workpiece is supplied and which is transported by a transport path has a reference member that is a reference for positioning of the workpiece. The carriage also has a fixing unit, whose motion is controlled by a control unit provided outside the carriage, that fixes the workpiece. The workpiece, which has been positioned in a first direction on the carriage and has not yet been fixed by the fixing unit, is pressed in a second direction against the reference member by a positioning unit, in which the second direction intersects with the first direction, and the workpiece is positioned on the carriage in the second direction.
