20100053250 | RECORDING APPARATUS - There is disclosed a recording apparatus including a feeding mechanism, a recording head, a position sensor, a determining portion, and a recording-head controller. The feeding mechanism feeds a recording medium placed on a feeding surface. The recording head ejects a liquid droplet onto the recording medium on the feeding mechanism. The position sensor outputs a detection signal when the recording medium being fed by the feeding mechanism reaches a predetermined position, and also when a liquid-droplet ejection area formed at a part of the feeding surface reaches the predetermined position. The determining portion determines whether the liquid-droplet ejection area reaches the predetermined position. The recording-head controller controls the recording head such that: (i) when the detection signal is not outputted from the position sensor, the recording head does not eject a liquid droplet, (ii) when the detection signal is outputted from the position sensor and the determining portion determines that the liquid-droplet ejection area does not reach the predetermined position, the recording head records on the recording medium an image desired to be recorded on the recording medium, and (iii) when the detection signal is outputted from the position sensor and the determining portion determines that the liquid-droplet ejection area reaches the predetermined position, the recording head prints on the liquid-droplet ejection area an image desired to be printed on the liquid-droplet ejection area. | 03-04-2010 |
