Abstract
An image fixing portion includes a drum of cylindrical shape provided on a conveyance passage, a magenta fluorescent lamp and a yellow fluorescent lamp installed near the axis of the drum, and a fixing portion guide guiding the roll paper to be conveyed along the inner wall of the drum on the conveyance passage. The magenta fluorescent lamp and the yellow fluorescent lamp are disposed so that their axial direction may be coincident to the axial direction of the drum. When the image fixation is made, the roll paper is led into the drum. The roll paper has its image forming area alone led into the inside of the drum, so that light from each fluorescent lamp is applied to the image forming area alone.
Claims7
A photo printer comprising:
- image forming means for forming an image by heating a roll paper having a plurality of thermally coloring layers on which images are formed at different heating temperatures, and fixed by lights having different wavelengths depending on the heating temperatures;
- image fixing means for fixing the image by applying a light to the roll paper on which the image is formed by the image forming means;
- wherein
- the image fixing means includes;
- an outside portion of cylindrical shape for accommodating an image forming area of the roll paper along an inner wall of the image fixing means, the outside portion having partly a notch;
- light radiating means including a plurality of line light sources for radiating a light having a wavelength in accordance with an image to be fixed, the plurality of line light sources being disposed at the positions substantially the same as a central axis of the outside portion of cylindrical shape along the central axis;
- light intercepting means for intercepting light from the light radiating means, the light intercepting means provided near the notch;
- and
- conveyance assisting means for leading the roll paper along the inner wall.
