Abstract
A conveyer includes: a supporting member which supports a roll body having a sheet wound therearound; a conveyance roller which conveys the sheet; a guide member; an urging member which urges the guide member; a sensor; and a controller. The controller is configured: to determine a target position of the guide member and a permissible position in accordance with the target position; to control a rotation amount of the supporting member and/or a rotation amount of the conveyance roller; to determine whether or not a position of the guide member exceeds the permissible position; and to perform a notification of a conveying error of the sheet.
Claims8
A conveyer comprising:
- a supporting member configured to rotate in a state that the supporting member supports a roll body in which a roll sheet is wound;
- a conveyance roller configured to convey the sheet pulled from the roll body in a conveying orientation;
- a guide member positioned upstream in the conveying orientation of the conveyance roller, configured to make contact with the sheet pulled from the roll body, and configured to move in a crossing direction crossing an axis of the supporting member and an axis of the conveyance roller;
- an urging member configured to urge the guide member in an urging direction including a component in the crossing direction so as to apply a tension to the sheet making contact with the guide member;
- a sensor configured to detect a position in the crossing direction of the guide member;
- and
- a controller configured to control rotation of the supporting member and rotation of the conveyance roller,
- wherein the controller is configured to execute:
- determination of a target position in the crossing direction of the guide member in accordance with a diameter of the roll body, and determination of a permissible position in accordance with the determined target position;
- controlling of a rotation amount of the supporting member, a rotation amount of the conveyance roller, or both of the rotation amount of the supporting member and the rotation amount of the conveyance roller such that the position in the crossing direction of the guide member becomes to be the determined target position;
- determination as to whether or not the position in the crossing direction of the guide member detected by the sensor exceeds the permissible position;
- and
- performing of a notification of a conveying error of the sheet in accordance with determination by the controller that the position in the crossing direction of the guide member exceeds the permissible position.
