Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a negative carrier moving device, and in particular is capable of making multiple prints without moving photographic paper.

2. Description of the Related Art Photographic printers typically print a sheet of negative film on a print paper of a certain width.

Problems that the invention aims to solve Recently, however, there has been a proposal that it would be possible to print different widths by dividing the width onto a single sheet of printing paper of the same width.

Means to Solve the Problem After repeated various prototypes and experiments, the inventor of the present invention was able to move the position of the negative carrier in which the negative film is set back and forth, thereby changing the optical axis and exposing only a certain part of the printing paper. If you change the position of the negative film and expose the remaining part of the print paper again, you will be able to print multiple prints of different widths on a certain width of print paper. By changing the negative film, you can obtain multiple prints with completely different designs. Therefore, in the present invention, the negative carrier is configured to be movable on the negative carrier table using the negative carrier base as an intermediary. That is, the present invention includes a negative carrier stand 1, a spring 2, 2 whose one end is fixed to the negative carrier stand 1, and whose other end is connected to pull one end of the set levers 3, 3, and whose other end is held by the negative carrier stand 1. Rolls 4, 4 provided near the center of the set levers 3, 3;
A U-shaped stopper 5a is attached to the guides 9, 9, which are always in contact with one side of the slide shaft 8, and which slide via integrated bearings 7, 7 on the slide shaft 8 attached to the negative carrier stand 1. a negative carrier 5 having a window 5b having a spring 5c for sandwiching a negative film;
By providing a negative carrier base 6 that slides on the negative carrier stand 1 integrally with the negative carrier 5 and to which the bearings 7, 7 are attached, and a limit protrusion 8a provided on the slide shaft 8. This is a negative carrier moving device that allows relative movement of a negative carrier 5 with respect to a negative carrier stand 1 within a movement limit.

Operation: With this configuration, the negative carrier can be moved reliably and accurately with respect to the negative carrier stand.

Embodiment Figures 1a, b, and c are perspective views of the main operating parts on the back side of the moving device of the present invention in different states, and Figure 2 shows the exposure of the printing paper being moved as the negative carrier moves. A schematic diagram showing the state, FIG. 3 shows a schematic oblique view of the negative carrier on the front side.

In the figure, reference numeral 1 denotes a negative carrier stand, and springs 2, 2 are symmetrically fixed on the negative carrier stand 1 at one end and connected to set levers 3, 3 at the other ends. One end of the set levers 3, 3 is fixed to the negative carrier stand 1, and the other end is pulled by a spring 2, 2, and the rolls 4, 4 are provided near the center of the guides 9, 9 so as to be always in contact with one side thereof. 5, the negative film printed by the negative carrier is fixed in the window 5b in the figure, by clamping the negative film to the negative press frame using the spring 5c on the negative plate stand as shown in FIG. A U-shaped stopper 5a is also attached. Reference numeral 6 denotes a negative carrier base, which is integrated with the negative carrier 5 and slides on the negative carrier stand 1, and an oil-less bearing 7 slides on a slide shaft 8 to move it to the negative carrier stand 1. This allows relative movement of the negative carrier base 6. It is assumed that the negative carrier 5 is located on a negative carrier base 6 and can move together with the negative carrier base 6. Furthermore, a projecting piece 8 is integrally provided on the slide shaft 8.
a is attached and slides within the U-shaped stopper 5a to determine the limit of movement of the slide shaft 8.
Thus, the window 5b ₀ where the negative film appears in Figure 1

If you want to shift the film position from 5b ₀ to 5b ₁ or 5b ₂ by moving the position back and forth, move the negative carrier base 6 directly or by adjusting a knob (not shown). base 6
This movement moves the integral negative carrier 5 and bearing 7 relative to the slide shaft 8, and at the same time the guides 9,9 cause the set levers 3,3 to move relative to the roll 4. As the negative carrier 5 moves, the position of the negative film moves back and forth from 5b ₀ to 5b ₁ or 5b ₂ , changing the exposure position of the negative film on the printing paper to B ₀ as shown in FIG.
It is possible to move from B ₁ to B ₂ . The first

shows the state in which the slide shaft 8 is biased with respect to the bearings 7, 7, that is, the windows to which the negative film is attached move from 5b ₀ to 5b ₁ and 5b ₂ , respectively, and from B ₀ on the print in Fig. 2. _B1 ,
The film image is transferred to _B2 and exposed.

Effects of the invention As described above, with this invention, the negative carrier 5 can be moved forward or backward for each exposure to perform back and forth exposure as shown in Figure 2, and then each screen can be cut into one sheet and used. This allows printing in different widths with only one type of paper size, eliminating the need to change paper when changing the size.
