    05 The invention relates to a photo technique, namely, devices for transportation during processing of a reversible film provided with a side notch. In photographic films, especially in low-format ones, the edges of the latter are adapted to be provided with side cuts, which in subsequent automatic processing of films serve as information carriers, for example, in the process of framing films. So, for example, in negative color or black and white negative films of small or pocket format, the side cut is made in such a way so that for each negative that can be copied there is one side cut in a certain place. Through even overexposed or underexposed, or completely unexposed places of the film do not receive side cutting. When passing through the printer, the film is transported by means of a friction drive through the frame frame of the apparatus and, at the same time, the edge of the film is read by means of a mechanical or optical device. If there is a side gouge, the drive stops. In this case, the negative side cut is in the correct position needed to make a copy, and since highly overexposed or underexposed areas of the film do not get side cut, in such cases the film is fed automatically. for further processing, the negative will not again fall into the frame of the printer. A device for transferring a film provided with side notches is known, comprising a switch and a switching element cooperating with the side notches tn. However, this device does not have enough speed; necessary in the process of framing films on framing machines. The aim of the invention is to respond to speed. The goal is achieved by the fact that a device for transporting a film equipped with side gaps containing an actuator, a switch and a switching element that interacts with side gaps additionally introduces an electromagnetic clutch and a second switch connected in the current circuit of the coupling parallel to the first switch, and the drive is made a clamshell mechanism consisting of a cam, whose axis is connected with an electromagnetic clutch, and interacting with one two-armed lever, the other end of which It is pivotally connected to a carriage on which a grab is installed, made in the form of a two-armed lever, one end of which interacts with the film cut-through, and the other is spring-loaded and mounted to cooperate with the second switchS mounted on the carriage, and the first switch is installed to interact with the additional inserted by the cam, rigidly connected to the shaft of the first cam. According to the invention, the reversible film is transported using lateral cuts, and the reversible film is transported only in a predetermined region of the distance - between the side cuts. In FIG. 1 shows schematically a device for transporting a film; in fig. 2 — grab that is not engaged; Fig, 3 grab. meshed with a side notch; in fig. 4 - a film with a side notch with a normal distance between frames, top view; in fig. 5 - a film with a side notch with a distance between, numbered frames. Smaller than normal, top view; in fig. 6 - film with a distance between frames longer than normal, top view; in fig. 7 - diagrams showing the coordination of the position of the switches and with the movement of the film. The diagram contains a disk t (the direction of rotation of the disk cam obsignal 1 {position 2); double-shouldered shooter 3h axis 4 dBl of its lever; connecting element 1-1ent 5; carriage 6: grab 7; axis 8 grapple; shoulder 9; rifer; first switch 10; control cam 1i; the second switch 1 / - ;: so-called; 4-coupling 13; spring 14 oast; h lseny; direction 15 dIdaek -, -; shortcuts; film 16; unfinished edge 17 of the film; direction 18 of the carriage movement; side notch 19 of the film; side 20 notches; 21 movement direction of the film.
    The device works as follows.
    To move the film, the cam cam 1 rotates in the direction of the arrow 2 and thereby oscillates two-arm lever 3. The shape of the curve is chosen so that the axis A of the two-arm lever with a small-format film passes a distance of 40 mm. The movement of the point of the axis 4 is transmitted through the movable connecting element 5 to the carriage 6 for moving the film 16, which, in a straight line in the directions 15 and 18, slides along a non-slip slip (not shown) and also passes a path of 40 mm. A grab 7 is mounted on the carriage 6 for moving the film. The latter can rotate on the axis 3. The arm of the grapple 9 is rigidly connected to this axis, which moves with the grapple 7 and at the same time acts on the first switch 10, which is rigidly connected to the carriage 6. On that The same shaft, on which the disk cam 1 is located, also has a control cam 11, which acts on the second switch 12. The switches 10 and 12 are turned on, in parallel, and the electromagnetic clutch 13 is actuated.
    The stretch spring 14 pulls the grab 7 into the side cut-out 19 of the film, however, the spring force is adjusted so that when the carriage 6 moves backwards in the direction 15, the grapple 7 slides out of the side cut-out 19, as shown in FIG. 2, passes along the non-cut edge 17 of the film, until, under the action of the spring force, at the end of the return stroke again falls into the next side cut-out 19 (FIG. 3).
    At the beginning of the next transport stroke in the direction 18, the front face of the grapple 7 is adjacent to the side 20 of the notch 19 and, therefore, pushes the film 16 in the direction of the arrow 21. The position of the axis of the grapple 8 is chosen so that the inward notch is reached using the feed force
    19 is the magnitude of the spring component 14, which would be sufficient for holding the grapple 7 in the slot with normal resistance to the movement of the film. However, with a significant resistance to the movement of the film, the front face of the grapple 7 may slip from the side 20 of the notch 19, and then without moving the film, move the carriage 6 to the final position.
    The control cam 11 is adjusted in such a way that during full retraction (direction 15 of the double-arm lever 3) it turns on the switch 12 so that the magnetic clutch 13 remains in the active state. This clutch establishes a connection between the drive motor (not shown) of the disk cam 1. In addition, the control cam 11 is made such an o6pa3OMj that it keeps the switch 12 on even when the movement direction of the carriage 6 has already changed (the transition from direction 15 to direction 18) and carriage 6 again moved in feed direction 18 by 4 mm. Now, in the further movement in this direction, the control cam 11 turns off switch 12. The magnetic coupling 13 will break with the drive or not, and therefore the connection between the motor and the disk cam 1 depends on whether the grapple 7 is in the side notch, when switch 10 operating as a switch is on, i.e. no effect. In this case, the magnetic coupling still remains active, while the normal movement of the film 16 takes place. However, if the grapple 7 is in the position shown in FIG. 2, the switch 10 is turned on by means of the shoulder 9 of the film grapple interrupted.
    Some characteristic cases are shown in FIG. 5, 4 and 6. In FIG. 4 spacing between two frames is 38 mm. This corresponds to the normal spacing between edges. The grapple 7 describes its target movement of 40 mm. At the same time, the grab 7 in position 7 first slides off the side notch 19, and then as it moves -1
    The rods 6 in the direction of the bus 18 enters the side notch 19 when idle 2 PvI. After passing the next 2 mt path switch 12, which is controlled by the control cam 11, is turned off. However, the film is completely moved. since the switch 10 keeps the magnetic coupling 13 in the active state.
    FIG. 5 shows densely arranged adjacent images, the distance between which is 36 mm. Here, the grapple 7 first idles in the direction of the feed movement5 in this case 4 mn. The movement of the film 16 is normal; since the switch 12 is turned off at the moment when the switch 10 is turned on. If the distance between the two images was less than 36 mm, then when turning off the switch 12, the switch 10 would not yet be turned on and the film movement would be interrupted.
    FIG. 6 shows a film with a distance between frames greater than normal. The images are located 40 mm apart from each other. 2 mm more than the normal pitch of the film. Here, at the end of the path of movement, the grab 7 falls just as far as the next lateral cut-through S, since the fixed path of the film movement mechanism is also 40 mm. When the switch 12 is turned off, after the passage of the 4 mm path, the grab 7 remains in the slot, i.e. switch 10 is turned on and the film path is completed completely. If the distance between the two images were more than 40 mm, then the grab 7 could get into the side notch 19. Consequently, the switch 12 of the grapple 7 would turn off in the position according to (pig 2 and the switch lOj would turn off.) The movement of the film would be interrupted.
    The positions of the switches 10 and 12 in dependence on the position of the carriage 6 are represented in the form of diagrams; -g FIG. 7, while the shaded area of the crossover 10 is the area in which even the axis is lito with tfc with ps1) the movement of the film 1-1 with (Deviation of distance mtf; T, at b (} kov1) with 1 notches from the normal)
    The final position of the grab 7, for example relative to the trimming device of the surrounding machine, is at a predetermined distance - (Figures 4, 5, 6). If the punching machine for side gaps is adjusted so that the side gaps are located. If the center of the frame is exactly the same, then this distance is exactly 19 MMs t. e. half the normal distance from 38 mm in a small format film. Since this distance in the framing machine is a predetermined value, each slit is not: a} depending on the distance to the next image, it is cut off in the final position of the Grapple 7 exactly along the edge of the image. This means that with the automatic mode of the framing machine, manual frame correction is not required until then. until the difference between the intervals does not exceed a value of +2 mm. According to the invention, with the help of t:, ld) kk; tey mezhkal.rovyh intervals, t.C .: using these small dng; individual range, you can be reliable; operate an automatic framing machine with a convenient framing system. Significantly large inter-frame spacing causes termination of the framing process, since if the distance between frames is less than 36 mm, the images overlap each other, and it is necessary to peiuaTb whether to frame one of the images; and the rest of the other image to cut or both of the overlapped images of beats; 1l t--: films.
