Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Application of Soil Collection This invention relates to a color printer, and more particularly to a color printer in which a light source can be moved depending on the document.

(Prior Art) In recent years, it has become an important technical issue for color printers to be able to produce a wide variety of color photographs according to the user's preferences. In other words, the problem is how quickly color photographs can be provided to users at a low cost and with the same image arrangement as printing, although the quantity is smaller than that of printing.

For this reason, for example, it is possible to print an image from a negative film onto photographic paper in the main exposure area, and then freely print original images such as text and illustrations in a sub-exposure area provided separately on the photographic paper. be.

When printing original images such as text and illustrations, the light source is fixed, so when you want to change the printing position and print various originals by partial exposure, the position of the original must be fixed. The printing position is determined by adjusting the conveyance amount of the photographic paper.

(Problem to be Solved by the Invention) By the way, when printing an image of a document such as characters or illustrations, the position of the document is changed in the sub-exposure section every time the main exposure section is exposed or after a predetermined number of sheets have been exposed. It may be burned. At this time, partial exposure relies on manual operations, such as adjusting the transport amount of photographic paper while keeping the light source fixed, and especially when changing the placement position of the document, so it is difficult to accurately position the document. It takes a lot of effort to do this, and the operation is troublesome.

Therefore, if the light source could be moved and exposed in accordance with the movement of the document, the document would only need to be set in a fixed location at all times. There is no need to perform cumbersome manual operations such as making adjustments or placing the original each time, improving the accuracy of editing.

This invention was made in view of the above-mentioned conventional problems.
An object of the present invention is to provide a color printer that allows easy setting of partially exposed originals and improves editing accuracy.

(Means for Solving the Problems) In order to solve the above-mentioned problems of the present invention, light from a light source is irradiated on the main exposure section that irradiates the negative film and on the original placed on the printing frame of the deck. In a color printer that is equipped with a sub-exposure section and prints a predetermined image on a photosensitive material,
The apparatus is characterized by comprising a document moving means for moving the document in the sub-exposure section to a predetermined position, and a light source moving means for moving the light source in the sub-exposure section in accordance with the movement of the document.

(Function) In this invention, a document is set and moved to a predetermined position,
Exposure is performed at 8 times so that the light source is aligned with the moving position of this document. In this way, partial exposure is performed simply by always setting the original at a predetermined position, so there is no need to manually change the original placement position each time, and the positioning accuracy of the original is improved.
