the embodiment of the invention described above will.

In Fig. 1, the optical block has a neutral position. If the splined shaft 1 is rotated through an angle of 90 ° under these conditions, the optiochen units 3 threaten each other together with it. This optical block 4 is raised to the point at which a sheet of copy paper 12 of the loading device 13 is opposite, so that the surface of the copier. papiero 12 is electrically charged by the charging device 13. If the loading device 1.3 passes completely over the exposed surface of the copy paper, it is opposite the mask 7. Before the light source 9 of the light projector 10 emits light under these conditions, the light passes through the positive film 5 and the lens 6 and projects the image of the film, which is refracted by the reflector 7 and with the prescribed color on the copy paper 12 arrives.

When the exposure is completed, the optical block 4 is moved downward along the spline shaft 1. While sicti the optical block 4 is in the upper position for carrying out the exposure, is used a positive _f sv File 5 with a new one, in a portion other m ° dos electronic copying machine replaced. liunmore should refer to Pig. 3 to 6, the operation of the film exchange mechanism 21 has been described. When the solenoid 32 is energized and the positive film 5 is brought to the underside of the removal rod 48, the engagement member 30 rotates counterclockwise.

counter to the force of the spring 35 by. With this rotation had previously held the projection 28 of the cam 29, withdrawn to the outside, and in return the other approaches Engagement pawl 34 the cam 29. When the. Cam 29 is released, the spring clutch 27 is actuated so that the shaft 23 of the normally rotating motor 22 over the shaft 25 the gears 24 and 26 rotates. The rotates accordingly Cam 29 clockwise and is brought to a standstill when its projection 28 strikes against the engagement pawl 34. The rotation of the cam 29 is applied to the arm 36 via the shaft 25 so that the first rotatable lever 37 is rotated clockwise * The rotation of this first rotatable lever 37 is transmitted via the coil spring 40, so .that the Carriage 38 is moved in the axial direction, and consequently the second rotatable lever 51 is rotated via the connecting rod 52. The front end of the carriage 38, which extends to the right in ■ Fig. 3 moves, goes through the openings in the film magazine 43 and pushes the lowermost of the superimposed, positive films 5 in the holding plate 46 for the films. if under these conditions, the front end of the positive film 5a abuts against the actuator 45 to rotate it, If the detector 54 detects the movement of the positive film 5a and sends a signal to the conveying and discharge device 17 for the copy paper so that copy paper is fed. On the other hand, when the actuator 55 is not rotated, i.e., when the positive film 5a is not inserted into the holding plate 46, the detector conducts. 54 to the conveyor and take-off device 17 a signal to stop the feed. At this time, the rotation of the second rotatable lever 51 causes the extraction rod 48 slides in the same direction as the carriage 38, namely to the right in Fig. 3. The used positive Movie. 5t), the. is in the holding plate 46 is, by the film take-up claw 50 grips before the subsequent film 5a is inserted into the holding plate 46 through the carriage "30,

When sloh the sled not moved properly because I got the positive JTiIm 5 in the magaain 43 or the positive film got caught wrongly in the Retaining plate 46 has been inserted, limiting the resulting higher tension of the spring 40 the rotation 4ts occur levers 37t When the first rotatable lever 37 does any further rotation executes, the pressure 37b against 4en Betftiiguseehebel | ta dee microswitch 41 pressed, so that;) every further power supply to the »AntriebEiechanienuie 21 (fig. 1} is interrupted. If the drive mechanism 21 stops * becomes the first rotatable lever 37 by the clockwise rotating moment of the coil spring 40 eurtick brought into its initial position, eo that the positive one Film is proven against damage *

The above-mentioned introduction of the positive pilous 5 is completed while the exposure is being carried out in another section. When the exposure is finished, the optical block is moved down. This is followed by development and fixation. At this time, the Solemoid 32 is turned off, and the interference member 30 rotates due dee rightward rotating torque of the spring 35 in Gegenuhr ζ Eiger sense, that is, the engaging pawl 34 is withdrawn from the squatting 29, and the other engagement pawl 53 approaches the squatting. Due to the subsequent release of the cam 29, the rotatable shaft 25 rotates due to the action of the spring clutch 27, so that the first and second levers 37 and 51 are pivoted via the arm 36 in the counterclockwise direction. When the projection 28 of the cam 29 abuts against the engaging pawl 33, the rotatable shaft 25 stops again in view of the spring clutch 27. The pivoting of the first and second levers 37 and 51 moves the carriage 38 and the removal rod 48 to the left in FIG. 3 and thus in a position in which these parts are prepared for the insertion and removal of further positive filae. When the slide 38 is returned from the magazine 43, the following is

Lowing positive PiIm 5 brought down under the pressure of the weight 44 and lies opposite the openings 45. A repetition of the aforementioned work cycle allows the positive film 5 in the magazine 43 to be inserted into the holding plate 46 piece by piece, and the used Ii ¹ Hm to be withdrawn from the holding plate 46 into the collector 47.

Upon completion of the exposure of a positive film 5 and his Replacing with a new PiIm will make a .12 in brought a tank 45 on the bottom, while • © si.durcä die Holding unit 11. is held. At this point, a Developing solution introduced into tank 45 via inlet 46, flows through the downward pipe 88, flows from the bottom of the tank 85 up and fills the upward tube 89. After the exposed Surface of the copy paper 12 is developed, v; is the developing solution from the tank through the outlet 8? deducted. A wash solution is then introduced through inlet 86, the developed surface of the copy paper for fixing washes. Like the developing solution, the washing solution is withdrawn through outlet 87. Then, the optical block 4 becomes light raised, and a finished copy paper 12. is waraie Air dried -which emerges from the nozzle 16 of the dryer 15.

While a sheet of copy paper 12 during development and Washing is held in the holding unit 11, which the. Demand- and take-off device 17 is opposite, it is initially in developed in a single color and then in several colors for the creation of a so-called electronic photographic After this picture has been printed by the electronic copier, - a new sheet of copier paper is fed in, ijunmore should the mode of operation of a device 'for conveying and Peeling off copy paper.
