Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a printing base plate for contact printing and stretch printing of a developed photographic film.

[0002]

[Prior art]

 Conventionally, photographic film developed in a photo lab has been delivered to retail stores in a negative bag made of transparent or translucent thin synthetic resin sheet. The image of this developed film consists of a series of top images that are continuous horizontally and vertically in multiple stages. At retail stores, this top image is suitable for contact printing and stretch printing. After selecting, the adhesion baking and the drawing baking were performed. For this selection work and printing work, the developed film is taken out from the negative bag, and the undeveloped film and the developed film or the developed film and the unexposed photographic paper are overlaid, and placed on the base 31 of the printer 30 shown in FIG. It was placed on a flat urethane 32 and pressed from above with a pressure plate 33 made of a transparent plastic plate or a glass plate, and in this state the frame image was visually selected and baked. .

However, the work for taking out and storing the developed film from the negative bag is not only complicated, but the development is performed between the urethane 32 and the pressure plate 33 on the flat base 31 of the printer 30. The work of keeping the pressured state under tension without sagging the finished film and unexposed photographic paper was also laborious and time-consuming.

[0004]

[Problems to be solved by the device]

 An object of the present invention is to select a frame image through a negative bag without holding the photographic film in the negative bag on the photographic base plate and pressing it with the pressure plate 33 as shown in FIG. In addition, the photographic film in the negative bag can be held on the photographic base plate in a tension state without sagging by an extremely simple operation. We provide a base plate for photographic film printing, which allows the exposure light to be radiated on the entire surface of the plate evenly, which makes it extremely easy, quick, and excellent to select and print a frame image. To do.

[0005]

[Means for Solving the Problems]

 The means for solving the problems of the present invention are as follows. The photographic base plate has a loose arc surface protruding upward in the front-rear direction, a negative bag fixing device is provided at the edge of the arc direction, and a pair of small holes opened at one end of the negative bag is provided for the protrusion. A base plate for printing photographic film that projects from an arc surface in the vicinity of the fixing device.

[0006]

[Action]

 The negative bag 20 containing the photographic film is placed on the loose arc surface 13 of the photographic base plate 11, and the small hole 22 of the negative bag is fitted into the protrusion 17 provided on the base plate 11, and the front fixing device, that is, the illustrated embodiment. In this case, cover the negative bag 20 with the pressing piece 14c to stop the upper edge of the negative bag, and squeeze the negative bag 20 against the arc surface 13 from the upper edge of the negative bag to the lower edge. The fixing device, that is, a fixing piece 19 which is separately formed in the illustrated embodiment, is pressed. Therefore, in the present invention, there is no need to press the pressing plate 33 as in a known printer, and therefore, the pressing plate is not required, and the surface of the photographic base plate 11 is formed by forming a gentle arc surface projecting upward in the front-back direction. Therefore, the negative bag containing the photographic film is held tightly and tightly without slack on the loose arc on the photo base plate, and the arc surface of the photo base plate is loosely formed. Therefore, the light emitted from above the photographic base plate is evenly distributed as in the case of illuminating a flat surface.

[0007]

【Example】

 1 to 4, an embodiment of a base plate for printing a photographic film according to the present invention will be described.

Reference numeral 11 is a photographic base plate having legs 12, and all or part (13a) thereof is formed of a magnetically attracting metal plate. The surface of the photographic base plate 11 is an arc surface 13 which is gentle in the front-rear direction. The above-mentioned arc surface 13 is projected on the upper surface side. Further, the above-mentioned gentle arc surface allows the entire surface of the photographic base plate 11 to be irradiated with light evenly when the photographic base plate 11 is irradiated with light such as light for exposure from above the photographic base plate. It has a gentle rounded surface.

A negative bag fixing device 14 is provided at one edge of the photographic base plate 11 in the arc surface direction. As shown in FIG. 5, the negative bag 20 is provided with a partition 21 for accommodating a film containing a number of frames and a pair of small holes 22 provided at the base end (close to one end edge). There is. As shown in FIGS. 3 and 4, the fixing device 14 of the illustrated embodiment fixes one piece 14a of the hinge to a mounting piece 15 fixed to the photographic base plate 11 and the other piece 14b of the hinge via a holding piece mounting piece 14d. The magnetic pressing piece 14c is fixed to the magnetic pressing piece 14c, and the magnetic pressing piece 14c is provided with a recess 16 into which a protrusion 17 described later is inserted. A projection 17 for inserting the small hole 22 of the negative bag 20 is projected upward at a position near one end edge of the photographic base plate 11 in the arc surface direction and corresponding to the recess 16. Has been done. Then, with the photographic film stored in the negative bag 20 as shown in FIG. 5, the small hole 22 of the negative bag 20 is fitted into the protrusion 17 and the magnetic pressing piece 14c is tilted down. The recess 16 is fitted into the protrusion 17 so that the negative bag 20 is pressed by the magnetic pressing piece 14c and the protrusion 17. Then, the open end of the negative bag 20 adsorbs and holds another fixing device, for example, a rod-shaped magnetic fixing piece 19 formed separately as the metal plate 11.

The photographic base plate 11 may be made of a magnetic material, and the holding piece 14c and the fixing piece 19 may be made of a magnetic material.

[0011]

[Effect of device]

 As described above, the present invention can hold a photographic film in a negative bag on a photo-printing base plate, select a top image and print without using a pressure plate. The photographic film in the negative bag can be held on the photographic base plate by a very simple operation without causing slack, and can be held in a tensioned state, and the photographic base plate is irradiated. Light for exposure or the like is uniformly irradiated on the entire surface similarly to the flat surface, so that it is possible to select, print the frame image very easily, quickly and satisfactorily.
