Description

The proposed machine is a conventional typewriter with small changes, allowing us to use it for photosetting, and the set is obtained line by line (tape) and has all the letters of a given size of the same width — therefore the machine cannot be used for a set of conventional printing publications , but only for printed works, where the difference in the width of the letters is not decisive, and for the production of text inscriptions on the exhibition material.

In FIG. 1 shows a diagram of the general appearance of the machine; FIG. 2-gear transmission to the belt mechanism; FIG. 3-register device; FIG. 4- device of the letter lever; FIG. 5- shutter action; FIG. 6-lighting device; FIG. 7 is a diagram of an optical device; FIG. 8 scheme for calculations.

As can be seen from FIG. 1, a photosensitive film of 1-2 of the same shape and width, protected from light by a transparent and painted case, is inserted in place of the tape of a conventional typewriter; instead of pads with letters, a frame 13 is installed with a play 14, on which are inscribed, the letters 26 of the respective font

(81)

(Fig. 4). For each font there are two plots, respectively, of the keyboard on the machine.

The letters 26 on the film in frame 14 are reduced to 1-2 points, which, with a height of 1 cm in the block, allows you to place from 5 to 10 double sets of fonts. An optical system 3 is attached to the bookbinder 4. When printed, the pad 13 strikes the diaphragm and the letter enlarged with the optics to the desired size is photographed on the photosensitive tape 2 propelled by the tape driver 5 attached to the opposite end of the optical system, and the tape is moved to a distance corresponding to the size of the letter. The typewriter carriage is removed, and a hole 29 is made under the ratchet wheels 10, which drive the gears 12 of the belt mechanism, which allows the ratchets 10 to be lowered and the wheel to be pushed not by 2, but by 4-6 teeth. The number of teeth by which the ratchet pushes the gear wheel 12, and hence the distance that the belt moves, is adjusted by the stand 8. By adjusting the height of the stand with the screws 22, 7, it is possible to change and push the dimensions. Simultaneously with the change in the height of the arrangement, the storage cells 10 are changed by the same installation and the optics 3, so that the variation of the pin and the stroke of the ratchets are matched.

A rail 19 is vertically mounted on the upper register key 18 along which the fork 24, 25 runs, the distance between the branches of which allows the register lever to move within two letters. The fork was strengthened with a screw 21 at a certain height, the round bar was raised to the desired height, i.e. it was set against the letter 4, a letter was needed. Within the two desired letters, the lever 20 of the register 18 with the lower register rests on the upper branch of the plug 24, and pressing the register key to the lower branch 25 of the fork is translated to the upper register. The letters 26 on the film are applied by photographing a large font size in a photographic apparatus, the letters being reduced to 1-2 points. The letters are made negative, i.e. white on a black background, since from the vice will be black on white. The distance of the frame 14 with the letters 26 from the pad Id must be such that the light incident on the side penetrates into the gap and is sufficient to produce a photo print.

Optics 3 consists of lenses that give the desired magnification, and this magnification is changed either by replacing the lens (revolving system) or by changing the distance of the system from the ribbon driver. The mechanism, which changes the magnitude of the increase, by the same installation 6, 7, according to a special pointer, changes the height of the position of the ratchets 10, which move the gear wheel 12 of the belt drive.

In order to actuate the shutter when pressing the keys, the lever 36, entering the lower leg 4, strikes the following shutter device: in the case 76, in which the optics 3 are located, in front there is a shutter 56 located between the planes 58 having a through hole 77 through which light passes to lens 65 from bulbs 60. Shutter 56 is a disk in which, at a certain equal distance, holes 59 are made with a diameter corresponding to the size of letters 26 on the block 13, the shutter disk 56 of circumference has teeth read so that the tooth pitch is equal to the distance between two adjacent holes 59. A ratchet 57 adjoins the teeth. When it moves, the top of the disk 56 moves and the hole 59 flashes at the through hole 77 for a period of time sufficient for exposure. The ratchet 57 is raised by the protrusion 55 of the wheel (it is in a restful state in the recess 54). The tabs are located around the circumference of the disk 53, which is tightly connected to the ratchet 78. The protrusions are designed so that they raise the ratchet 57 by the pitch width of the teeth 56. When the lever 52 is pushed forward, it advances the disk 53 and the ratchet 55 moves with it, and the ratchet 57 moves from it moves the disk 56 with the holes 59. The lever 52 by the spring 51 returns to its original position. It ends with the head 50 entering the initializer 4. The lever 16 strikes it and provides the exposure. For illumination of the supplied letter to the optics, each plate 75 bordering the initializer is screwed onto a light installation consisting of a light bulb 60 with a reflector 61 and a condenser 62. The light installations go beyond the edge of the pad 75 and provide-. The illumination of the letter with light passing through the condenser is bred on both sides. In the optical system, there is a fixed literal object in the frame; 14 and screen (film 2 If we take the size of the letter on the block into 1 point, and the height of the film is 10 mm, then we can get the gradation of pins from b to 20th, i.e. an increase from b to 20 times will be required The change in magnification can be obtained by changing the main focal length of the lens 65 and its distance from the film 2. If we take the conventional pins b, 8, 10, 12, 16, 20, then we need to ensure that the lenses have different curvatures. from the bookbinder 4 to the ribbon driver 5, we can, for example, take in 10 cm (100 mm. Denoting (Fig. 8) through p the distance from tera to the lens 65, and through the / from the lens to the film-2,

based on the well-known formulas, we can say that p B5 so many times must be greater than p, what time b more a. If by L we denote the increase, that is, the ratio of b to fi, then

At THIS, the letters are between the focal and double-focal lengths, and a real, enlarged and reversed image is provided (i.e., the characters must be on the film in an inverted).

Optical system 3 has the following device. In the case 76, which rests at one end on the buzzer and the other on the tape feeder, there is a shutter 5G and a lens 65. The lens 65 is mounted on a curvilinear support 73, where there are lenses of all the sizes listed above. The support 73 is moved by the screw 81 on the pointer, where the angle of rotation for each pin is indicated. Lens 65 is fixed in case 64, which is moved in case 76 by screw G8 through teeth 67-66 on pointer 69. Support 73 is enclosed in case 80, which prevents light from penetrating into it. A screw 68 that moves the cover 64 is associated with a screw 22 through 6 of 6, which determines the height of the ratchetta stand 10. Thus, with one turn, a lens and a ratchet are mounted on the desired pin, which moves the tape 2 to the distance, respectively, of the dial. The device 71-72 has the following purpose: if the letters are negative (white on a black background), then the size of the hole 70 does not play a role. If for some reason it will be necessary to make the letters positive (black and white), then, in order to avoid exposing the film 2, the opening 70 must correspond to the pins. In this case, the movement of the screw 68 through the bar 72 is transferred to the gear 71 and changes the size of the hole 70 in the pin. A screwdriver manually sets the required lens with a screw 81, changes the lens distance from the letter with a screw 69, changes the span of the ratchet 10 to the tape drive and, if necessary, the size of the hole 70 is all in size.

When typing, first install screw and skittle with screw 22 and write in normal order. On the move, 11, 1 flat tape 2, you get a photograph of 9.1 7, / letters. The tape, as required, from 5, 9 is cut and exhibit or develop in 4, 8 faces.

The typed material is formed in the desired size of the line or is arranged for subsequent work according to a pattern or layout.

Proofreading is done by replacing erroneous words with new ones.

The subject matter of the invention.
