Abstract
Abstract There is provided an image recording apparatus to record an image onto a recording sheet in a facsimile apparatus or the like. This recording apparatus comprises: a recording head for recording an image onto the recording sheet; a rotary platen roller for conveying the recording sheet; a guide member for guiding the recording sheet along the peripheral surface of the platen roller; and a device to rotatably support the guide member around the rotary shaft of the platen roller as a rotational center. The recording head is arranged so as to be come into pressure contact with the peripheral surface of the platen roller. A pair of cam members for separating the recording head away from the platen roller are attached integrally with the guide member. With this apparatus, even if the sheet holder and platen roller are closely located, the recording sheet can be easily inserted into the gap therebetween. The apparatus can be miniaturized.
