TECHNICAL FIELD OF THE INVENTION
The present inventionPaper mask device and printing exposure deviceAnd a paper mask positioning device for fine-tuning the inclination angle of a mask openingMask Apparatus and Printing Exposure ApparatusIt is about.
[0002]
[Prior art]
Recently, an index print photograph in which images of all frames recorded on a photograph film are displayed in a list has been provided. Such an index print photograph is created by reading each frame of the photo film by a film scanner and printing and exposing the image of each frame on a color paper using a liquid crystal display panel or the like, for example, so as to arrange the images in the matrix. You.
[0003]
In this case, an image of, for example, five sub-frames for one line is displayed using a liquid crystal display panel or the like, and is printed and printed on color paper. The sub-frame image of the frame is printed and exposed. Hereinafter, in the same manner, for example, an index image of 5 × 5 frames is printed and exposed. In this way, the printing exposure of the sub-frames of each row is performed in such a way that if the sub-frames of all the frames are to be printed at the same time, the number of pixels of the liquid crystal display panel increases and the liquid crystal display panel becomes expensive. This is because the photographic printer cannot be made more compact as the size of the printer increases.
[0004]
[Problems to be solved by the invention]
At the time of printing exposure of the sub-frames of each row of the index image, if the loading position of the paper mask is shifted and slightly inclined, as shown in FIG. 14, the sub-frames SF of each row are cut obliquely by this inclination. As a result, the quality of the index image is reduced. A rectangular frame 2 shown in FIG. 14 shows an exposure area on the color paper 3 by the mask opening of the paper mask, and is a case where the paper mask is set in a slightly inclined state. In this case, one or both ends of each sub-frame SF are cut obliquely, resulting in an unsightly index image.
[0005]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and has made it possible to easily and accurately adjust the inclination of a mask opening.Paper mask device and printing exposure deviceThe purpose is to provide.

[0035]
As shown in FIGS. 5 and 8, the mask positioning device 57 includes a rotation holding unit 87, a mask holding frame 88, and a shift unit 89 for slightly shifting the mask holding frame 88 in the vertical direction. I have. The rotation holding portion 87 is formed of a bearing, and as shown in FIG. 5, is arranged at the center in the vertical direction at the innermost portion of the guide groove 55 a of the mask guide plate 55. The rotation holding portion 87 is brought into contact with a rotation concave portion 52d as a rotation center formed at the tip of the paper mask 52, and the positioning of the mask in the insertion direction of the paper mask 52 is performed. The turning recess 52d is formed in an arc shape corresponding to the outer diameter of the bearing.
[0036]
As shown in FIG. 8, the mask holding frame 88 is formed in a rectangular cylindrical shape, and a support bearing 88a as a guide member is disposed at the center of the upper and lower ends in the cylinder. Both side edges of the paper mask 52 come into contact with the support bearing 88a, and hold the paper mask 52 from above and below. In addition, instead of the support bearing 88a, the guide member may be constituted simply by a cylindrical body, a columnar body, an arc-shaped projection, or the like.
[0037]
The shift portion 89 includes a shift frame 90 that holds the mask holding frame 88 so as to be slidable in the vertical direction, and an eccentric cam 91. The shift frame 90 is formed with two vertically long guide holes 92, and a guide roller 93 projecting from the mask holding frame 88 is fitted into the two vertical guide holes 92, whereby the mask holding frame 88 in the shift frame 90 is fitted.

A lateral guide hole 94 that is long in the lateral direction is formed in the shift frame 90, and an eccentric cam 91 is fitted in the lateral guide hole 94. Therefore, by rotating the eccentric cam 91, the mask holding frame 88 is slightly moved according to the eccentric amount of the eccentric cam 91.DisplacementWill do. The vertical direction of the mask holding frame 88DisplacementAs a result, the paper mask 52 is slightly rotated about the rotation holding portion 87 as shown by a two-dot chain line in FIG. 5, whereby the inclination of the paper mask 52 is finely adjusted. In this manner, the mask holding frame 87 is slightly moved by the eccentric cam 90.DisplacementAfter that, the screw of the eccentric cam 91 is turned to fix the eccentric cam 91, thereby fixing the position of the mask holding frame 88 in the shift frame 90. In addition, a lateral guide groove may be provided on the mask holding frame 88 side, and an eccentric cam that enters this lateral guide groove may be provided on the shift frame 90 side to shift the holding frame 88.
[0038]
When finely adjusting the inclination of the paper mask 52, a grid-like chart 97 serving as a reference of the inclination is projected onto the paper mask device 16 by the index image printing exposure unit 17 as shown in FIG. 9. (A) shows an example of the projection of the grid chart 97 before the fine adjustment, and (B) shows an example of the projection of the grid chart 97 after the fine adjustment. Before the fine adjustment, since the paper mask 52 is inclined as shown in (A), the distances L1 and L2 between the horizontal line (reference line) 97a of the grid chart 97 and the lower edge of the mask opening 52a of the paper mask 52 are equal. However, the mask opening 52a is inclined. In the fine tilt adjustment, the eccentric cam 91 is rotated so that the distances L1 and L2 indicating the degree of tilt between the horizontal line 97a of the grid chart 97 and the lower edge of the mask opening 52a become equal to L3 in (B). .
[0039]
The projection of the chart 97 may be performed by focusing on the photosensitive emulsion surface of the color paper 12 or by focusing on the surface of the paper mask 52. In this case, the grid chart 97 is enlarged and projected on the periphery of the mask opening 52a so that the horizontal line of the grid chart 97 and the upper and lower edges of the mask opening 52a are parallel. After finely adjusting the inclination of the paper mask 52, the grid chart 97 is printed and exposed on the color paper 12 and developed, and the horizontal line of the grid chart 97 of the developed color paper 12 is compared with the horizontal line. The inclination may be corrected by observing the degree of parallelism with the upper and lower edges of the mask opening 52a.
[0040]
Next, the operation of the present embodiment will be described. In normal photo printing, each frame of the photo film 42 is sequentially set at a print target position, and photometry and imaging of the print target frame are performed by a scanner. Next, the LATD and the scene characteristic value are obtained based on the photometric data, as is well known, and the printing exposure amounts of three colors are calculated based on the LATD and the scene characteristic value. The set position of each of the filters 38 to 40 is determined based on the three-color printing exposure amount. After the filters 38 to 40 are set at the set positions and the light quality of the printing light is adjusted, the shutter 43 is fixed. By opening for a time, the image of the print target frame is printed and exposed on the color paper 12. The color paper 12 subjected to printing exposure is stored in a loop shape in the second paper reservoir 27, and then sent to a paper processor 28 where it is developed. As is well known, the developed color paper 12 is separated for each frame based on the cut mark, and is united for each case based on the sort mark. The image data of each frame is stored in the memory 46, an index image is created in a predetermined format based on the image data of each frame, and this is stored in the memory 46 of the controller 45.
[0041]
When printing and printing the index image, the index image paper mask 52 is set in the paper mask device 16. In this case, as shown in the flowchart of FIG. 10, first, the identification mark 61 of the paper mask 52 is read by the mask type sensor 60, and the controller 45 sends the paper mask 51 set on the print stage 15 based on this detection signal. , 52 are for index images or for character printing. When the paper mask is used for printing characters, an alarm for replacing the mask is displayed and a warning sound is sounded, so that the operator is notified of a mask loading error.
[0042]
As shown in FIG. 5, when the index image paper mask 52 is inserted into the paper mask device 16, the rotation concave portion 52 d at the tip of the paper mask 52 comes into contact with the rotation holding portion 87. This contact positions the paper mask 52 in the mask insertion direction. Next, the grid-like chart 97 is projected onto the paper mask 52 side by the index image printing exposure unit 17, and the parallelism between the horizontal line 97 a of the grid-like chart 97 and the upper and lower edges of the mask opening 52 is observed. Then, the mask holding frame 88 is shifted as shown in FIG. 8 so that the upper and lower edges of the mask opening 52a are parallel to the horizontal line 97a serving as the reference line. The shift of the mask holding frame 88 is performed by rotating the eccentric cam 91.
[0043]
Next, it is detected whether or not the lamp box 53 is set. This detection is performed when the lamp box 53 is set on the print stage 15 because the lamp box 53 is connected to the power supply via the connector 71. Is detected. Note that, besides detecting the presence or absence of the lamp box 53 based on a change in the resistance value due to the connection, the presence or absence of the lamp box may be simply detected using a microswitch, a photoelectric sensor, or the like.
[0044]
When the lamp box 53 is set on the print stage 15, an instruction to remove the lamp box 53 is displayed and a warning sound is emitted. Thus, the lamp box 53 is removed from the paper mask device 16. Therefore, when the index image is printed, the lamp box 53 is not erroneously printed with the lamp box 53 loaded in the paper mask device 16. When the lamp box 53 is to be removed, the side cover of the printer processor 10 is opened and the handle 64 is pulled out to pull out the lamp box 53 from the lamp box guide frame 58. Since the side cover is opened when the lamp box 53 is removed, the color paper 12 is pulled back to the magazine 11 side from the paper mask device 16, so that the color paper 12 is not exposed. . Instead of pulling the paper 12 back to the magazine 11, a blind plate may be set on the paper mask device 16 so that the paper 12 is not exposed.
[0045]
In the print exposure of the index image, a title column 101, which is the first line image LP1 as shown in FIG. 7, is displayed on the liquid crystal display panel 81 shown in FIG. 2, and this is subjected to print exposure. After the printing exposure of the title column 101, the paper 12 is sent by one line, and a line image LP2 including five sub-frames of the next second line is printed and exposed. Hereinafter, similarly, the row images LP3 to LP6 are sequentially printed and exposed, so that one index image is printed and exposed.
[0046]
Although the index image is printed after the exposure of each frame of each order after the exposure of the frames is completed, the index image may be printed in a batch for each order.
[0047]
When creating a greeting card, a paper mask 51 for printing characters is set on the paper mask device 16. As shown in FIGS. 1 and 3, the paper mask 51 is provided with a lith film 59 for greetings such as "Merry Xmas" and "Happy New Year", which is prepared in advance, and a squirrel film mounting step 51d of the paper mask 51. (See FIG. 3). In this case, as shown in the flowchart of FIG. 11, first, the identification mark 61 of the paper mask 51 is read by the mask type sensor 60, and the controller 45 detects the paper mask 51 set on the print stage 15 based on this detection signal. , 52 are for index images or characters. When the paper mask is for an index image, an alarm for mask replacement is displayed and a warning sound is sounded, so that the operator is notified of a mask loading error.
[0048]
Next, it is detected whether or not the lamp box 53 is set. When the lamp box 53 is not set on the print stage 15, an instruction to mount the lamp box 53 is displayed and a warning sound is emitted. Thus, the lamp box 53 is attached to the paper mask device 16. This attachment is performed by first setting the light box 53 on the light box guide frame 58 and pushing out the handle portion 64 in the setting direction. When the connector is set to the lighting position, the connector 71 is connected to the connector on the printer processor 10 side, so that the attachment of the light box 53 is detected by a change in the resistance value of the connected connector.
[0049]
When the lamp 65 emits light for a certain period of time, the character image of the lith film 59 is printed and exposed on the color paper 12. After the printing of the character image, the color paper 12 is fed frame by frame, a new unexposed portion is set on the print stage 15, and a predetermined number of characters are printed.
[0050]
In the photographic print stage 20, the image of the photographic film 42 is overexposed to the frame on which the character printing has been performed. This overlapping exposure is performed for a predetermined number of sheets. The printed color paper 12 is developed by a paper processor 28 and then cut into individual frames to create a greeting card.
[0051]
