Abstract
A printing apparatus (printer) is provided in which a base material is conveyed by a roll-to-roll method and feedback control is performed on a tension imposed on the base material, and which includes a control unit, a first drive motor (front drive motor) configured to control a speed of conveyance of conveying the base material, and a second drive motor (feeding motor, rear drive motor, winding motor) configured to control the tension imposed on the base material. In a case where a conveyance operation for conveying the base material is stopped based on detection of a foreign object, and when a speed of the first drive motor is at a predetermined value or less, the control unit stops the tension control performed by the second drive motor.
Claims6
A printing apparatus in which a base material is conveyed by a roll-to-roll method and feedback control is performed on a tension imposed on the base material, the printing apparatus comprising:
- a control unit;
- a first drive motor configured to control a speed of conveyance of conveying the base material;
- and
- a second drive motor configured to control the tension imposed on the base material, wherein
- in response to determining that an emergency stop of a conveyance operation is to be performed, the control unit is configured to:
- cause the first drive motor to stop;
- and
- when a speed of the first drive motor is at a predetermined value or less, cause the second drive motor to stop controlling the tension imposed on the base material.
A printing method of a printing apparatus in which a base material is conveyed by a roll-to-roll method and feedback control is performed on a tension imposed on the base material, and which includes a control unit, a first drive motor configured to control a speed of conveyance of conveying the base material, and a second drive motor configured to control the tension imposed on the base material,
- the printing method comprising:
- determining that an emergency stop of a conveyance operation for conveying the base material is to be performed;
- stopping, by the control unit, the first drive motor;
- determining, by the control unit, that a speed of the first drive motor is at a predetermined value or less;
- stopping, by the control unit, the second drive motor for controlling the tension imposed on the base material.
