  • Patent number: 10248070
    Abstract: There is provided a transportation apparatus in which a first transportation unit, which transports a paper sheet from a mounting portion, starts transportation of a next paper sheet at a time when a specific time has elapsed after the second transportation unit, which is positioned on a downstream side of the first transportation unit, starts to transport a paper sheet so that an inter-sheet distance between a preceding paper sheet and a following paper sheet becomes optimal.

  • Patent number: 10148836
    Abstract: An image reading apparatus includes a reading portion that reads an image on a target object; a motor that cause the reading portion to move; and a control portion that controls the reading portion and the motor. Further, in a case where the motor does not enter a step-out state, the control portion executes a first reading operation that causes the reading portion to read the image simultaneously with causing the motor to cause the reading portion to move at a high speed, and in a case where the motor enters the step-out state, the control portion executes a second reading operation that causes the reading portion to read the image simultaneously with causing the motor to cause the reading portion to move at a low speed, and generates image data having a resolution lower than a high resolution corresponding to the low speed.

  • Publication number: 20170343085
    Abstract: Provided are a recording apparatus and a motion unit drive method that determines a stop rotation torque of a CR motor indicating stop of a carriage by a stopper and, within a predetermined period after the determination of the stop rotational torque, supplies to the CR motor the drive signal that causes a rotational torque of the drive motor to be a low rotational torque having a smaller torque value than the stop rotational torque.

  • Patent number: 9527280
    Abstract: For a lenticular in which a lens body having low shape accuracy is disposed on one end portion, when the other end portion of the lenticular is detected, a position of a carriage at the time of detecting the end portion of the lenticular is stored in a buffer as a paper end position, a carriage motor is controlled such that the carriage is separated from a home position and moved in a main scanning direction, and a printing head is controlled such that an ink discharge having a color according to printing data is started at the paper end position. Since the lens body having high shape accuracy is disposed on the end portion of the lenticular, it is possible to land the ink onto a more suitable position with respect to the lens body, thereby allowing printing quality to be improved.

  • Patent number: 9481170
    Abstract: When printing is performed by discharging ink from a printing head onto a lenticular, a carriage motor is controlled such that a carriage is moved in a main scanning direction at a velocity which is slower than a movement velocity of the carriage at the time of performing a normal printing process with respect to a recording medium different from the lenticular as a recording paper and further separated from a home position, and the printing head is controlled such that an ink discharge having a color according to printing data is started with respect to an end portion of the lenticular, and thus the printing of one pass is started. Since the velocity is slower than the movement velocity of the carriage at the time of performing the normal printing process, it is possible to improve printing quality at the time of performing printing with respect to the lenticular.

  • Patent number: 9233561
    Abstract: A lens sheet is provided with a lens layer which is formed by arranging lenses, which extend in a y direction as a first direction, in a plurality of lines in an x direction as a second direction which is a direction which is orthogonal to the first direction, and an ink absorbing layer which configures a surface on the opposite side with regard to a surface which is configured by the lens layer, where the thickness of an edge which is an end surface on one side of the lens layer in the x direction is thinner than the thickness of an edge which is an end surface on the other side. The printer performs recording from the edge which is a reference side toward the edge on the opposite side.

  • Patent number: 9104958
    Abstract: In order for skew relative to the transport direction to be detected in a sheet which is transported to a recording unit, a carriage is initially moved in a scanning direction to a first position and the sheet is transported in this state. Then, when the front edge of the sheet in the transport direction is detected by a second sensor, the carriage is moved in a direction so that the second sensor is no longer able to locate the front edge to a second position, which is separated from the first position by a regulating movement distance. Furthermore, the sheet is transported to where the second sensor locates the front edge of the sheet in the transport direction at the second position and skew in the sheet is detected based on this transport distance and the regulating movement distance.
