Medium transport apparatus, printer, plotter and combination of printer and plotter

A printer comprising:

• a medium transport apparatus comprising:
• a feeding roller configured to rotate around a rotational axis;
• a guide rail extending along the rotational axis;
• a slider supported by the guide rail and movable along the rotational axis;
• a rotatable pinch roller configured to clamp medium between the feeding roller and the pinch roller to move the medium;
• a lever connected to the pinch roller and movable to change a clamping state with respect to the medium between the feeding roller and the pinch roller;
• and
• an arm connected to the slider and configured to take an engaging position where the arm moves the lever to change the clamping state when the slider moves along the rotational axis and a standby position where the arm is not engaged with the lever when the slider moves along the rotational axis.

A plotter comprising:

• a medium transport apparatus comprising:
• a feeding roller configured to rotate around a rotational axis;
• a guide rail extending along the rotational axis;
• a slider supported by the guide rail and movable along the rotational axis;
• a rotatable pinch roller configured to clamp medium between the feeding roller and the pinch roller to move the medium;
• a lever connected to the pinch roller and movable to change a clamping state with respect to the medium between the feeding roller and the pinch roller;
• and
• an arm connected to the slider and configured to take an engaging position where the arm moves the lever to change the clamping state when the slider moves along the rotational axis and a standby position where the arm is not engaged with the lever when the slider moves along the rotational axis.

A combination of a printer and a plotter, comprising:

• a medium transport apparatus comprising:
• a feeding roller configured to rotate around a rotational axis;
• a guide rail extending along the rotational axis;
• a slider supported by the guide rail and movable along the rotational axis;
• a rotatable pinch roller configured to clamp medium between the feeding roller and the pinch roller to move the medium;
• a lever connected to the pinch roller and movable to change a clamping state with respect to the medium between the feeding roller and the pinch roller;
• and
• an arm connected to the slider and configured to take an engaging position where the arm moves the lever to change the clamping state when the slider moves along the rotational axis and a standby position where the arm is not engaged with the lever when the slider moves along the rotational axis.

A medium transport apparatus comprising:

• feeding means for rotating around a rotational axis;
• guide means extending along the rotational axis for guiding;
• sliding means for sliding on the guide means along the rotational axis;
• rotatable pinch means for clamping medium between the feeding means and the pinch means to move the medium;
• lever means for changing the clamping state with respect to the medium between the feeding means and the pinch means;
• and
• arm means for moving the lever means to change the clamping state when the sliding means moves along the rotational axis in an engaging position and for not engaging with the lever means when the sliding means moves along the rotational axis in a standby position.
