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.

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.

Abstract: A sheet supplying apparatus, in which a user can select either automatic sheet feeding or manual sheet feeding, 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 first sensor that detects a leading end portion of the sheet separated from an outer circumferential surface of the roll, a second sensor that detects the leading end portion which is manually set in a conveyance path by the user, and a determination unit configured to determine whether or not automatic sheet feeding is performed on the basis of a detection result of the second sensor.

Abstract: It is an object of the present invention to provide a sheet supplying apparatus which is capable of winding the sheet tightly. A sheet supplying apparatus according to the present invention 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, in which, 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 smaller than a predetermined value.

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 the 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.

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

Abstract: An air-conditioning indoor unit includes a blow-out port, a Coanda vane and a controller. The Coanda vane is-provided in proximity to the blow-out port. The Coanda vane turns the blown air into a Coanda airflow along a bottom surface of the Coanda vane. The controller performs a control in which a direction of the Coanda airflow is directed in a first direction by positioning the Coanda vane in a first orientation, and the direction of the Coanda airflow is directed in a second direction different from the first direction by positioning the Coanda vane in a second orientation different from the first orientation.

Abstract: An air-conditioning indoor unit causes a flow of air blown out from a blow-out port to be diverted in a predetermined direction due to the Coand{hacek over (a)} effect. The air-conditioning indoor unit includes an airflow direction adjustment vane varying a blowout angle of blown air relative to a horizontal plane, a Coand{hacek over (a)} vane turning the blown air into a Coand{hacek over (a)} airflow along a bottom surface, and a control unit. The Coand{hacek over (a)} vane is provided in proximity to the blow-out port. The control unit executes an airflow direction automatic switching mode automatically switching between a Coand{hacek over (a)} effect use state in which the blown air is turned into a Coand{hacek over (a)} airflow along a predetermined surface and diverted in the predetermined direction, and a normal state in which the Coand{hacek over (a)} airflow is not created.

A convex shaped curved surface formed in the bottom surface of the Coanda vane has a radius of 50 to 300 mm. The controller adjusts the orientation of the Coanda vane away from a casing front surface as the Coanda vane separates from the blow-out port in the Coanda effect use mode.
