Abstract
There is provided a resistance generating device including a resistance generating unit disposed inside the rotation axis, the resistance generating unit having an inner ring and an outer ring, one of the inner ring and the outer ring being combined with the rotation axis and the other one of the inner ring and the outer ring being combined with the fixed part, the one being rotated with respect to the other one while generating a rotational resistance, and a switch part disposed inside a surface of the rotation axis.
Claims8
A resistance generating device comprising:
- a rotation axis that rotates with a roll formed by winding a long recording medium;
- a fixed part disposed outside the rotation axis in a longitudinal direction of the rotation axis, the fixed part allowing rotation of the rotation axis while being fixed to an outside;
- a switch part disposed inside a surface of the rotation axis;
- and
- a resistance generating unit disposed inside the rotation axis, the resistance generating unit having an inner ring and an outer ring, one of the inner ring and the outer ring being combined with the fixed part, the one being rotated with respect to the other one of the inner ring and the outer ring while generating a rotational resistance;
- wherein, the switch part is configured to switch the resistance generating unit between a combined state and a non-combined state in accordance with an operation from outside,
- wherein the resistance generating unit is operative to generate the rotational resistance in the combined state and the resistance generating unit is unlocked in the non-combined state.

A recording apparatus comprising:
- a rotation axis that rotates with a roll formed by winding a long recording medium;
- a fixed part disposed outside the rotation axis in a longitudinal direction of the rotation axis, the fixed part being fixed to an outside and being rotated with respect to the rotation axis;
- a resistance generating unit disposed inside the rotation axis, the resistance generating unit having an inner ring and an outer ring, one of the inner ring and the outer ring being combined with the rotation axis, the one being rotated with respect to the other one of the inner ring and the outer ring while generating a rotational resistance;
- a switch part disposed inside a surface of the rotation axis, the switch part configured to switch the resistance generating unit between a combined state and a non-combined state in accordance with an operation from outside,
- wherein the resistance generating unit is operative to generate the rotational resistance in the combined state and the resistance generating unit is unlocked in the non-combined state;
- and
- a recording head for ejecting ink toward the recording medium pulled out from the roll.
