1. A recording device comprising:
a recording unit configured to perform recording on a transported recording medium;
a facing unit disposed facing the recording unit, the facing unit including
a support surface configured to support the recording medium,
a negative pressure chamber provided on an opposite side of the support surface from the recording unit,
a plurality of suction ports provided in the support surface and configured to put the negative pressure chamber and an outside of the support surface in communication with each other, and
a partition mechanism provided in the negative pressure chamber and configured to divide the negative pressure chamber by being rotated; and
a driving unit provided separately from the facing unit and configured to drive the partition mechanism; wherein
the partition mechanism includes
a partition wall extending inside the negative pressure chamber and configured to be displaceable between an open position in which the partition wall is horizontally positioned with respect to a bottom surface of the negative pressure chamber and a closed position in which the partition wall is vertically positioned with respect to the bottom surface,
an abutting unit coupled to the partition wall and extending outside of the negative pressure chamber, the abutting unit being configured to displace the partition wall, and
a coupling unit disposed at a bottom of the negative pressure chamber and configured to couple the partition wall and the abutting unit, the coupling unit including a rotation center of the partition mechanism,
the driving unit includes
a driving source configured to rotate and
a cam configured to rotate the abutting unit in conjunction with rotation of the driving source and thereby displace the partition wall between the open position and the closed position,
the coupling unit couples the partition wall and the abutting unit with a predetermined idle angle, and
in an open state, a horizontal surface of the partition wall is aligned at the same height with the bottom surface of the negative pressure chamber.
