    摘要: In an image recording apparatus having a recording head, recording may be interrupted (for example, to permit transfer of new image data after a predetermined amount of recording is performed). Recording quality is maintained by compensating for the change in head temperature which occurs during the interruption. This is done by detecting the temperature of the recording head and/or counting the interruption time, and driving the recording head in a stand-by mode or correcting the image signal in accordance with the temperature difference between interruption and resumption of recording.

    摘要: An image recording apparatus has a stand-by mode in which a recording operation is interrupted during recording for stand-by. The apparatus includes a recording head for recording on a recording medium, a head temperature detecting device for detecting the temperature of the recording head, a memory device for storing temperature information detected by the head temperature detecting device when recording in the stand-by mode is interrupted, a stand-by time counting device for counting an interruption time for recording operation in the stand-by mode, and a head driving controlling device for transmitting a driving signal to the recording head. The controlling device is responsive to a temperature stored in the temperature memory device and an interruption time calculated by the stand-by time counting device on resumption of a recording operation after it is interrupted and the apparatus is placed in the stand-by mode.
