DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a slide film positioning mechanism when the slide film is conveyed to a printing section and printed.

Conventionally, in printers that print slide film (mounted film), the dimensions of the slide and light film mounts are not standardized, so there is no printer equipped with a slide film positioning mechanism, which makes it difficult to quickly process large amounts of slide film. I couldn't do it. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a slide film positioning mechanism that enables a printer to quickly process a large amount of slide film.

This invention will be explained below.

FIG. 1 shows a schematic structure of a printing system to which the present invention can be applied. A magazine 2 in which a large number of slide films 1 are arranged and housed is installed in a predetermined position of a printer 4, and After printing the slide film l taken out one by one with the printer 4, it is transferred to another magazine 3.
It is designed to be stored in. Here, the printer 4 includes a transport section 41 that takes out the slide film 1 from the magazine 2 and transports it in the X direction, a print section 43 that prints the image of the slide film 1 on a roll of photographic paper 42, and a printer I.
A print stand 44 for fixing the position and focusing of the slide film 1 at a time, a light source 45 for print exposure disposed below the print stand 44, and a print stand 44 for moving the printed slide film 1 from the print stand 44 in the N direction. and a conveyance section 46 that conveys it to the magazine 3 and sends it out to the magazine 3. In this invention, the printing table 44 is provided with a slide film positioning mechanism.

In such a configuration, the slide film l is taken out from the magazine 2 and conveyed via the conveyance section 41, and reaches the top of the print table 44. Here, in the present invention, the slide film 1 is automatically positioned appropriately in the front, rear, right, and left directions on the printing stand 44. Thereafter, the slide film 1 is printed onto a roll of photographic paper 42 at an optimum exposure amount calculated based on the results of measurements taken in advance. After printing is completed, the slide film 1 is transferred to the transport section 46
It will be transported and stored in the magazine 3.

FIGS. 2(A) to 2(C) are views showing one embodiment of the alignment mechanism of the present invention, in which FIG. 2(A) is a plan view, FIG. 2(B) is a plan view of the back side, and FIG. C) is a side view; pudding;・

, 7B are disposed, and each receives a force pulled in the outward direction indicated by the arrow by a spring (not shown). In addition, there are bottle pieces 81A, θIB, 71A, and 71B in the center of the 7 ride pieces GA, 8B, 7A, and 7B, respectively, and these pins pass through the grooves (not shown) of the board 5 to be engaged and connect to the back side. has reached. There are pins 51, 52, 5 on the back side of the board 5.
3 is arranged, and a substantially semicircular ring-shaped rrf moving piece 8 is provided through the guide grooves 81 and 82 in the pins 5'l and 52, respectively.
are engaged, and the pins 53 and 51 have guide grooves 91, respectively.
．． A semicircular ring-shaped movable piece 9 is engaged through 92. The semicircular ring-shaped movable pieces 8.9 are each subjected to a pulling force in the illustrated PI and Ql directions by springs (not shown). A small kite piece lO having a slope that engages with a pin 71B is attached to one end V of the semicircular ring-shaped movable piece 8 with screws IIA and IIB so that the position can be finely adjusted, and a pin is attached to the other end W of the movable piece 8. ? A small guide piece 12 with a slope that engages with the screw 13 is attached so that the position can be finely adjusted.
It is being interrogated by A and 13B. Similarly, a small guide piece 14 with a slope that engages with the pin 81A is attached to one end X of the semicircular ring-shaped movable piece 9 by means of screws 15A and 15B, and a pin f (with a slope that engages with IB) is attached to the other end Y of the semicircular ring-shaped movable piece 9. A small guide piece 16 is attached with screws +7A and 17B.Furthermore, U-shaped frames 23 and 24 are attached to the sides of the moving pieces 8 and 9, respectively. A pusher JPP 18 shown in FIG. Similarly, it is fixed to the frame 24.The protrusion 22B of the rotary solenoid 22, which rotates around the shaft 22A, is connected to the push rod 18.20.
The tip portions TPI and TP2 are engaged with each other.

In such a configuration, the rotorin Reno (1.22
When 44518. is not activated, the protrusion 22B pushes 44518.
In order not to push 20 in the N direction shown in the figure, push the 18
．． The springs 19.21 whose ends are fixed to one side of the disc-shaped protrusions LPI and LP2 of 20 are not compressed by the force, and the frame bodies 23.24 are not subjected to the force to rotate in the N direction. Therefore, the movable pieces 8, 9 to which the frames 23, 24 are fixed, respectively.
are respectively shown in P2. It does not receive the force of rotation in the Q2 direction,
Since the springs 83 and 93 receive only the forces that move toward Pi and Ql, the movable piece 8 is moved to the one end 8 of the guide groove 81.
1A is in contact with the pin 51, and one end 82A of the guide groove 82 is in contact with the pin 52. Similarly, in the ffr moving piece 9, one end 91A of the guide groove 91 is in contact with the pin 53, and the guide groove 9 is in contact with the pin 51.
One end 92^ of the pin 2 is in contact with the pin 51. Therefore, since the guide piece 10 fixed to one end of the movable piece 8 comes into contact with the pin 718 at the lower end 10A of the slope, the slide piece 7B to which the pin 71B is fixed is not subjected to an inward pulling force but is pulled outward by a spring. , the guide piece 12 is the lower end 12 of the slope
Since it contacts the pin 71A at point A, the slide piece 7A to which the pin 71A is fixed is not subjected to an inward pulling force but is pulled outward by a spring. Similarly, the guide pieces 14 and 18 fixed to the movable piece 9 are located at the lower end of the slope +4A and I8A, respectively.
Since the slide pieces 8A and BB are in contact with the pins fl1A and EIIB, the slide pieces 8A and BB are not subjected to an inward pulling force but are pulled outward by a spring.

Next, when the slide film l is conveyed to the center of the substrate 5, the rotary lenoid 22 is activated and the shaft 22A is moved.
The springs 19.21, whose ends are fixed to the disc-shaped protrusions LPI and LP2 of the push rods 18.20, respectively, rotate in the R direction with the push rods 18.20 as the center.
A frame body 23 receives a compressive force in the direction and has its other end fixed.
, 24 in the R direction. At this time, the springs 19 and 21 are resisted by the force of the springs 83 and 93, which rotate the movable piece 8.9 to which the frame body 23.24 is fixed in the PI and Q1 directions, respectively. is strong, so the frames IB and 17 are rotated in the R direction without being compressed, and the frames 18 and 17 are rotated in the R direction, respectively.
The movable pieces 8 and 3 to which the frame pairs 18 and 17 are respectively fixed resist the force of the springs 83 and 93 and move to P2. It is rotated in the CI2 direction. Accordingly, the guide piece lO fixed to one end of the movable piece 8 comes into contact with the pin 71B at the upper end 10B of the slope, so that the slide piece 7B, which is added by 161 points of the pin 718, is affected by the force of the spring pulling outward. The small guide piece 12 moves inward against the resistance, and the small guide piece 12 pins at the upper end 12B of the slope. 1A, the small slide piece 7A to which the pin 71A is fixed moves inward against the force of the spring pulling outward, and the small slide pieces 7A and 7B touch the pair of sides of the mount of the slide film l. They make contact with each other to perform left and right alignment. Similarly, the guide piece 14.18 fixed to the movable piece 9
are pins 131A at the upper ends of the slopes 14B and 18B, respectively.
, since it comes into contact with BIB, slide small piece 8A,
8B moves inward against the force of the spring pulling outward, contacts the other pair of sides of the mount of the slide film l, and performs front-to-back positioning.

Then, the slide pieces 8A, 88.7A, and 7B move according to the size of the mount of the slide film 1, and the front, rear, left, and right alignment is completed, resulting in the state shown in FIG. 2(A). In this state, move the movable pieces 8 and 9 to P2 respectively.
, Rotate in direction Q2 and slide small pieces 8A, 6B, 7A
, 7B inward, requires a strong force that may damage the mount of the slide film l, but 19 and 21 are compressed in the R direction by push rods 18 and 20 from the rotary solenoid 22, respectively. Upon receiving the force, the frame bodies 23 and 24 try to rotate in the R direction. At this time, the springs 19 and 21 resist the force of the spring 83.93 which rotates the movable piece 8.9 to which the frame body 23.24 is fixed in the PI and Q1 directions, respectively, and also resists the force of the spring 83. It encounters such strong resistance that it cannot move any further unless it injures it.

Therefore, the spring 19.21 is compressed as shown in FIG. 5 without causing the frame bodies 23, 24 to rotate in the R direction, and pushes the rotation of the rotary linenoid 22 in the R direction, causing only the movement of the forest 18.20. Stop and do not apply more force than necessary to the slide film 1. When the rotary solenoid 22 rotates by a predetermined amount, it stops at that position, thus completing a series of positioning operations. The slide film 1 is opened by the operation.

In the above embodiment, the movable pieces 8 and 9 have been described as having a semicircular ring shape and rotating, but the present invention is not limited to this embodiment. It is not necessary to form it into a semicircular ring shape. The point is that the structure should be such that the pair of slide pieces can be moved by the same amount of movement at the same time. In addition, although the embodiment of the rotary solenoid 22 has been described as the drive source, if the pusher 18. It goes without saying that a known drive source such as a pressure type piston can be used.

As described above, in this invention, quick positioning in the front, rear, left, and right directions can be automatically performed according to the size of the slide film, and the slide film has an escape mechanism that does not apply unnecessary force to the slide film. It has the advantage of not damaging the mount.
