  • Publication number: 20240025191
    Abstract: A roll sheet with a continuous sheet wound in a roll form is rotated in a forward direction to supply the sheet to a printing unit. A sensor whose output is changed in accordance with a distance between the sensor and the sheet is used. A rotation direction of the roll sheet is switched from an opposite direction to the forward direction on the basis of the output of the sensor during rotation of the roll sheet in the opposite direction.

  • Publication number: 20240011248
    Abstract: A speed compensation part included in a construction machine executes a feedback control of regulating an opening degree of a second control valve to an opening degree obtained by subtracting a correction amount from a second target opening degree of the second control valve, when a combined manipulation is performed and a preset load determination condition is satisfied. The correction amount is calculated by the speed compensation part so as to be larger as a speed difference between a first target speed and a first actual speed becomes larger, the first target speed being a target speed of a first actuator and determined on the basis of a manipulation amount of a first instructive manipulation, the first actual speed being an actual speed of the first actuator.

  • Publication number: 20230347666
    Abstract: A roll sheet, in which a continuous sheet is wound in a roll form, is caused to rotate in a forward direction to supply the sheet to a printing unit. First and second sensors are arranged at positions facing an outer circumferential surface of the roll sheet and deviated in an axis line direction of the roll sheet. Outputs of the first and second sensors are changed in accordance with a distance to a sheet of the roll sheet. A rotation direction of the roll sheet is switched from a forward direction to a reverse direction on the basis of the outputs of the first and second sensors while the roll sheet is being rotated in the reverse direction.

  • Publication number: 20230227282
    Abstract: A sheet supplying apparatus, which is capable of winding a sheet tightly, includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a sensor that detects a leading end portion of the sheet separated from an outer circumferential surface of the roll, and a contact body that presses the outer circumferential surface. Before the sheet is fed, in a state in which the contact body presses the outer circumferential surface, the driving unit causes the roll to continuously rotate in the second direction until a detection cycle of the leading end portion by the sensor is less than a predetermined value.

  • Patent number: 10597247
    Abstract: Automatic sheet feeding of an installed roll is performed more reliably. To this end, a leading end of a sheet is detected on the basis of a change in an output value of a sensor while causing a roll to rotate in a winding direction using a sensor capable of detecting a distance to the sheet separated from the roll. After the detection, the roll is caused to rotate in a feeding direction, and a feeding state of the sheet is determined on the basis of a change in the output value of the sensor.

  • Patent number: 10421299
    Abstract: In a sheet supply apparatus, a type of sheet to be used can be specified using a sensor that detects a sheet separated from a roll at the time of automatic sheet feeding. The sheet supplying apparatus includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a sensor that detects the sheet separated from an outer circumferential surface of the roll, and a specifying unit. In a case in which the sensor detects a leading end portion of the sheet while the roll is being rotated in the second direction, the driving unit changes a rotation direction of the roll from the second direction to the first direction and feeds the sheet, and the specifying unit is configured to specify a type of the sheet on the basis of an output of the sensor while the roll is being rotated in the second direction.
