Abstract:
1. An ink jet recording apparatus comprising: a carriage for mounting therein a recording head which executes a recording operation by discharging ink onto a recording material and for executing an reciprocating motion; a conveying roller for conveying the recording material in a direction which crosses a moving direction of the carriage; a cap for covering a discharge port of the recording head; a pump for generating a suction force in an interior of the cap; and a drive transmission mechanism for transmitting a driving power of the conveying roller to the pump, wherein the pump is driven with a delay of a predetermined time from a forward/reverse switching of the conveying roller; and lock means which locks the carriage at a capping position where the discharge port is covered with the cap, wherein the lock means moves simultaneously with the forward/reverse switching of the conveying roller, wherein, when the lock means is in an active state, the lock means can be switched to the non-active state by movement of the carriage toward the cap.
