A tape dispenser housing wound adhesive tape includes a brake spoke tapering (i.e., narrowing) from a distal radial end to a proximal radial end relative to a tape rotational axis, wherein the brake spoke effectuates the braking of wound adhesive tape on a hub by contacting the wound adhesive tape, the hub, or both simultaneously.

Provided is a medium supply device including a spindle that supports a medium having a roll shape, a supplying portion that supplies the medium supported by the spindle toward outside, a plurality of support rollers that support the medium in positions between the spindle and the supplying portion, a moving roller that, in a contact position between the support rollers, is capable of coming into contact with a bridging medium extending across the support rollers in a state where a load is applied to the bridging medium and that is capable of moving from the contact position to a non-contact position of non-contact with the bridging medium, and a moving mechanism configured to move the moving roller from the contact position to the non-contact position.

A sheet conveyor includes: a holder that detachably holds a sheet roll; a rotation measuring device that measures a rotation amount of the sheet roll; a conveyance roller that conveys a sheet pulled out from the sheet roll held by the holder; a tensioner that is provided between the holder and the conveyance roller and that contacts with the sheet pulled out from the sheet roll toward the conveyance roller; a position detector that detects a position of the tensioner; a motor that generates driving force for rotating the conveyance roller; and a controller that controls the motor. The controller estimates a diameter of the sheet roll based on a conveyance amount of the sheet caused by rotation of the conveyance roller, a rotation amount of the sheet roll measured by the rotation measuring device, and a position of the tensioner detected by the position detector.
