Medium supply device and recording device

A recording device comprising:

• a receiving portion configured to receive an electrically conductive spindle including a shaft portion extending through a roll body on which a medium is wound, the spindle being configured to hold the roll body;
• a displacement member disposed at the receiving portion and configured to be displaced to an advanced position at which the spindle is covered and a retracted position at which the spindle is exposed;
• and
• a recording unit configured to perform recording on the medium, wherein
• the receiving portion includes
• a support portion abutting an outer peripheral surface of the shaft portion of the spindle and configured to rotatably support the spindle, and
• a drive gear meshing with a driven gear provided at an end of the shaft portion of the spindle to rotate the spindle, and
• the displacement member includes:
• a pivoting shaft configured to pivot between the advanced position and the retracted position;
• an abutting portion abutting the outer peripheral surface of the shaft portion of the spindle when the spindle is installed at the receiving portion, the abutting portion being configured to cause the displacement member to pivot from the retracted position to the advanced position around the pivoting shaft;
• an opposing portion abutting, at the advanced position, the outer peripheral surface of the shaft portion of the spindle installed at the receiving portion;
• a cover portion configured to, at the advanced position, cover the driven gear;
• and
• a grounding member contacting, at the advanced position, the spindle, thereby coupling the spindle to a ground potential.
