Abstract
An ink jet recording apparatus having a sheet forward roller,and a pump unit,connected to a single drive motor,, and a drive force is transmitted to the pump unit,through time lag mechanisms,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.
