Abstract

An ink jet recording apparatus having a sheet forward roller 8 and a pump unit 11 connected to a single drive motor 7, and a drive force is transmitted to the pump unit 11 through time lag mechanisms 33-34 that cause a time lag at the time of switching rotational directions. Sheet feeding/discharging operation and ink sucking operation are performed with the single drive motor by taking advantage of a timing at which there are no load fluctuations accompanied by the switching operation, without requiring any switching mechanism.
