Claims (1)

[Claims for Utility Model Registration] (1) A thermal head in which a heating element for one line generates heat by a heat pulse supplied based on image data, and a heating element interposed between the thermal head and the recording paper. An ink film that transfers the ink to the recording paper by the heat generated by the recording paper, a sub-scanning means that simultaneously sub-scans the ink film and the recording paper, and a heating element of the thermal head that sends heat pulses based on image data. , a control means for outputting a sub-scanning signal to the sub-scanning means at a predetermined timing, and a detection means for detecting black data included in a first line of image data; An image recording apparatus comprising: a leading edge margin control means for controlling the size of the leading edge margin of the recording paper based on the black data of the leading line. (2) When the content rate of black data in the leading line is less than or equal to a preset standard value, the leading edge margin control means causes recording of the leading line to start from a preset recording position, and records the black data. The image recording apparatus according to claim 1, wherein when the content rate is equal to or higher than the standard value, recording is started after feeding the recording paper by a predetermined amount in the sub-scanning direction. (3) When the image recording device is a facsimile device and the leading edge margin control means indicates that the reception mode of the facsimile device is a predetermined reception mode,
After feeding the recording paper by a predetermined amount in the sub-scanning direction, recording is started, and when the mode is not in a predetermined reception mode, the size of the leading edge margin of the recording paper is controlled based on the black data of the first line of the image data. An image recording device according to claim 1 or 2 of the utility model registration claim, characterized in that:
