Media conveyance device, printer, and control method of a printer

摘要

A printer takes up slack in media while suppressing excessive rewinding, and can check the movement of a movable member that moves following change in tension on the media. The printer drives the supply motor in a first operating mode in a slack removal operation that rewinds the recording paper (media) onto a paper roll 2, and stops driving the supply motor when the tension lever (movable member) moves from a slack-side first position toward a second position. In the movement checking operation, the supply motor is driven in a second operating mode with greater output than the first operating mode, rewinds the recording paper on the paper roll, and sets the tension lever to the second position.

主权项

1. A media conveyance device comprising:
a conveyance mechanism that conveys continuous media delivered from a paper roll through a conveyance path; a drive motor that rotates the paper roll; a movable member disposed to the conveyance path between the paper roll and the conveyance mechanism, and movable between a first position and a second position different from the first position following change in the tension on the media; a urging member that urges the movable member from the second position toward the first position; a position detector that detects the current position of the movable member; and a control unit that drives the drive motor in a first operating mode and rewinds the media onto the paper roll until the movable member moves from the first position to a specific position toward the second position, and
drives the drive motor in a second operating mode with greater output than in the first operating mode, rewinds the media onto the paper roll based on the current position of the movable member, and moves the movable member from the specific position to the second position.
