Abstract:
A medium supply apparatus supplying a rolled medium includes a tension member contacts to the medium to apply a tension to the medium, a state switching part that switches states of the tension member between first and second states, and a control unit. The tension member is swingable between a first position at which a first corner angle (θ1) and a second position at which a second corner angle (θ2) is formed, the second corner angle (θ2) being greater than the first corner angle (θ1). The control unit causes the state switching part to switch the state of the tension member to the fixed state in the first position when the medium is supplied, the control unit causes the state switching part to switch the state of the tension member to the releasing state in the first position when the control unit does not receive an image forming start signal for a predetermined period, and the control unit causes the state switching part to switch the state of the tension member to the fixed state when the tension member reaches the second position.

Claim (Index 1):
A medium supply apparatus, comprising:\n a holder that is configured to rotatably support a medium, which is wound in a rolled shape and to be rotated by a drive part, a conveyance part that conveys the medium in a conveyance direction, and is disposed in a downstream side with respect to the holder in the conveyance direction, a tension member that is disposed between the holder and the conveyance part, and contacts to the medium, which is positioned between the holder and the conveyance part, to apply a tension to the medium, a state switching part that has a detection sensor that detects a position of the tension member and switches states of the tension member between two states in correspondence with a detection result by the detection sensor, one state being a fixed state where the tension member is locked such that the tension member is not movable, and the other state being releasing state where the tension members is not locked such that the tension member is movable, a control unit that controls the drive part for the holder, conveyance part, and the state switching part, wherein the tension member is swingable between a first position at which a first corner angle (\u03b81) is formed and a second position at which a second corner angle (\u03b82) is formed, the first and second corner angles being determined with two tangent lines formed on the tension member which are seen from a rotational axis view of the holder, one tangent line being at an upstream contact point (UCP) where the medium comes in first contact with the tension member, and the other tangent line being at a downstream contact point (DCP) where the medium, which curves around an outer peripheral of the tension member, departs from the outer peripheral of the tension member, the second corner angle (\u03b82) being greater than the first corner angle (\u03b81), the control unit causes the state switching part to switch the state of the tension member to the fixed state in the first position when the medium is supplied, and the control unit causes the state switching part to switch the state of the tension member to the releasing state in the first position when the control unit does not receive an image forming start signal, which is a signal to start an image forming process, for a predetermined period after the conveyance part stops conveying the medium so that the tension medium is moved to the second position as the drive part drives the holder to rotate in an opposite direction to the conveyance direction, and the control unit causes the state switching part to switch the state of the tension member to the fixed state when the tension member reaches the second position.
