Description

[Detailed description of the invention] The present invention relates to a print mask device for printing images onto photographic paper, and more specifically to a print mask device that allows a print mask to be easily attached to and removed from a print mask support. .

As is well known, B size or
3S size (89mm x 89mm), E size (82.5mm x approx.
115mm) and other sizes are available, especially E
In terms of size, there are slightly different lengths such as 114 mm, 117 mm, and 120 mm for the same photographic paper width (82.5 mm). In addition, the prints of each size above are available as "bordered" or "borderless".
processing can be performed selectively. Print processing of these various sizes is used as promotional material for DP stores to customers, and customers' requests for printing processing vary widely.

In addition, when printing on photographic paper of the same paper width (117 mm), by changing the magnification of the printing device's lens, the width is 117 mm x length 82.5 mm, and the width is 117 mm x length 165 mm.
It is also possible to print in two sizes (mm).

With reference to FIG. 1, a case will be described in which a conventional drop-in type print mask apparatus is used to meet the above-mentioned customer's demands and to print in different sizes.

The small holes 4 of the print mask 1 are fitted into the two positioning pins 6 provided on the print mask support 5, and the print mask 1 is placed on the print mask support 5. Next, the photographic paper from the feed roller (not shown) is guided in the direction of arrow C of the photographic paper guide section 3 via the feed guide roller 8, and is wound up by the take-up roller (not shown) via the drive roller 8. It is mounted so that it can be The print mask 1 is covered with a cover 9 equipped with a photographic paper pressure bonding mechanism and the like. Print preparation is now complete.

If you want to replace the print mask 1 during printing, first raise the cover 9 to a position where it does not interfere with the removal of the mask, then loosen the photographic paper sufficiently and remove it in front of the print mask 1. Lift the side upwards with respect to the support stand 5 and remove it from the positioning pin 6.

When replacing a print mask in such a drop-in type print mask device, not only must the photographic paper on the print mask 1 be loosened, but also the photographic paper pressure bonding mechanism, backing device, etc. located above the print mask must be replaced. The drawback is that the mechanism used for this method must be moved each time to a position where it does not interfere with the attachment and detachment of the print mask.

Variable print mask devices have been proposed as a means of solving the above-mentioned drawbacks, but they are generally extremely expensive.

Furthermore, in the case of test firing, the mask width is usually 25mm.
Since the change is performed only at a certain level and is not within the variable range of the variable print mask, there is also the drawback that the print mask must be replaced.

The present invention has been devised to solve the above-mentioned drawbacks of conventional print mask devices, and provides a print mask device in which the print mask can be replaced without moving components other than the print mask. The purpose is to

To achieve this purpose, the print mask device of the present invention includes a print mask having an opening,
A print mask guide portion having a sliding groove for slidably supporting the print mask, a locking device for fixing the print mask, and a photographic paper support provided independently of the print mask. , a guide block having pins for positioning;
A photographic paper guide portion is provided with a sliding groove for slidably supporting the guide block.

Next, the present invention will be explained in detail using FIG.

The print mask device according to the present invention includes a print mask 1' having an opening 2', and a photographic paper guide section 30 having a sliding groove 21 for sliding the mask 1' in the y direction. There is. The position of the print mask opening 2' relative to the print mask support 5' is defined by distances A and B, respectively;
A can be finely adjusted between the sliding groove 21 of the print mask guide section 20 at both ends of the print mask in the x direction and the auxiliary plate 40, and the distance B in the y direction can be adjusted by adjusting the distance between the end surface 60 of the print mask 1 using a magnet or the like. It is determined by being attracted by the stopper 50. Furthermore, independently of the print mask 1', a photographic paper guide section 30 is provided, which is provided with a guide block 33 having a pin 32 and a sliding groove 31 for determining the position of supplying the photographic paper to the print mask opening 2'. ing.

Therefore, if it is necessary to change the photographic paper width, before or after replacing the print mask 1',
The position of the photographic paper guide section 30 will be changed. In this case, the position can be easily changed by, for example, pulling up the pin 32, moving the guide block within the sliding groove 31, and dropping the pin into a different positioning hole.

In the print mask device of the present invention configured as described above, the print mask 1' can be replaced without changing the condition of the photographic paper mounted between the photographic paper guide section 30 and the feeding side guide roll 8. Pull the mask 1' toward you and remove the locking tool 50 and the end surface 6.
By releasing the attraction due to the magnetic force between the print mask 0 and the print mask support 5' and sliding the print mask in the sliding groove 21, it can be removed from the print mask support base 5'. Further, when inserting a desired print mask, it is only necessary to engage the print mask in the sliding groove 21 and push it in until the end surface 60 of the print mask and the locking tool 50 are magnetically coupled. This is the photographic paper guide section 30
By providing the cover 9 independently of the print mask 1', the print mask can be replaced without changing the position of the cover 9, which is located above the photographic paper and is equipped with a crimping mechanism, etc. It is something that

Therefore, the print mask apparatus according to the present invention enables rapid printing processing in accordance with various sizes requested by customers, and greatly contributes to improving work efficiency.
