Abstract

Usage: in optical copying equipment, in particular in animation. SUMMARY OF THE INVENTION 1 The device comprises a light guide bundle, the input and output ends of which are located in one plane so as to allow the image to be transferred from one film frame to another. For this, the fibers in the bundle are rotated by 180 ° in layers. This allows the still part of the image to be copied when creating cartoon films. 1 silt

Description

The invention relates to optical equipment, which allows to combine both the image projection mode in the form of drawings in one closed system, and initially to create these drawings by drawing directly on the film according to the rules for creating multiplication by transferring the projection of the drawing from the drawn frame to the next one.

Devices for projecting various kinds of images are known, containing in their concept a light source, a tape drive mechanism with a drive, an optical system, a film channel, a screen.

As an example of such a known device can cite av.sv. USSR No. 822132, class C 03 B 21/00, 1979, where a system of prisms is introduced into the device to form a three-dimensional image.

In another similar device auth. USSR № 325587, cl. G 03 B 21/10, 1970 the original is the relative position of the reflecting mirrors included in the optical system, which ultimately

allows you to improve the incoming image on the screen.

These known devices, despite the differences therein, are essentially various kinds of projectors designed to display in advance the film or other image carriers. Consequently, in these devices themselves it is not possible to simultaneously create drawn images and, in particular, directly on the film, especially according to the principles of creating multiplication.

Devices are known that allow creating an animation containing several coaxially mounted and fixed plates, on one of which an image is applied and where a technique such as transferring an image to a secondary basis is used (e.g., U.S. Patent No. 4569577, cl. 352-87, 1986 ).

However, to create animated films with such a device, additional equipment is required that would transfer all the images to captivity.

ku, and in order to show such films, at least a film projector is also required.

Thus, a complex and complex system is required in the complex, which, for example, for home use, for creating and showing animated films is not possible.

The closest technical solution to the invention is a device for copying drawings (including frames of cartoons) on a desktop, containing an illuminator mounted on a table, glass, a device for turning a picture, a projecting device and holders (German Patent No. 2931074, cl. G 03 B 21/132, 1981.

In this device, the projecting and image-wrapping unit is made in the form of a glass sheet and a system of mirrors under it, which only allows to project the images, and they must be carried out in advance by other means. Thus, if all these constructions are combined, which allow these images to be executed and projected, then a cumbersome system consisting of self-contained units will be obtained.

The purpose of the invention is to enhance the functionality of the device by ensuring the transfer of the pattern from the previous frame to the next frame of the same tape.

The goal is achieved due to the fact that in the device containing the illuminator, the device projecting and wrapping the image, the latter is made in the form of a light guide bundle, the ends of which are located in one plane, and the fibers in the layers located along the direction of transfer are rotated 180 °.

Thanks to this constructive implementation, it became possible to draw the animation directly on the film, and the drawing process is facilitated by the fact that it was possible to create a transfer of the projection from the drawn frame to the next one. This property helps to orient in the frame space for applying the next phase of motion onto it.

The drawing shows a schematic of the proposed device.

It comprises a housing 1 in which the light source 2 is located in the form of a glow lamp. A capacitor 3 is located under the light source. It is rotatably fixed on the inner side of the housing and is made in the form of a box without side walls. The tape mechanism contains a U-shaped frame 4, the cross section of which is provided with holes a, b and c. The transverse hole a exceeds by 3-4 mm the window of the drum 5, and the other two parallel holes of the bivs are designed for clamps b of perforation of the film 7. Bearings 8 and 9 are installed in the side walls of the casing, in which the shafts 10, respectively, are fixed under the drum and 11 are punched carcass 12 interconnected through the parasitic gear 13, so that they rotate in one direction with the same speed.

The drum is a hollow cylinder with a transparent liner in the shape of a parallelepiped inside it. The cylinder itself has four symmetric rectangular holes that are parallel to the faces of the liner and

0 have a frame size of 14 films. The perforation coil also has the shape of a cylinder, on the end parts of which circular flanges 15 are provided. They have a diameter greater than the diameter of the cylinder of the perforation coil, and trapezoidal teeth 16 are provided on their side surfaces for engagement with the perforation of the film. In the housing is a system of flat mirrors 17, 18. 19, 20, 21

0 rectangular shape. They are located at different angles (30 °, 120 °). In the system of mirrors between the mirrors 17 and 18 there is an objective lens 22 for focusing the image. At the top

5, the housing panel 23 is fitted with a matte screen 24. It is oriented towards the mirror 21, is made of a transparent material and is enclosed in a frame 25 of dark opaque material. Under the top panel of the case

0, the light guides 26 are fixed, which function as an organ transmitting the image. They have the form of a loop, the end parts of which are directed toward the film channel 27, in which the film is located. Each of the end parts is directed to the adjacent film frames and is rotated on the whole by i80 ° relative to each other. In turn, the fibers of the optical fibers of one of the end portions of the loop are rotated 180 ° with respect to their location in the other end portion. Due to this implementation, the light guides ensure the identical and identical arrangement of the patterns on both its ends.

5 The device has a frame 28 frame.

The construction can operate in two modes: the animation drawing mode and the viewing mode; personnel or in motion.

In the first mode, film 7 is laid in the film channel 27 so that its first and second frames 14 are located under the ends of the loop of light guides 26. In the first frame, an image is drawn that is transmitted by the fibers to the second, adjacent frame. At the end of the drawing, in the first frame there is a drawing to be drawn on the second with some offset from the projected image. After the drawing is finished, the second frame moves the film by hand through the tape mechanism from itself by exactly one frame so that the last frame drawn and the new frame of the film are located exactly under the ends of the optical fiber loop. The film is again fixed by the clips 6 and the drawing process is repeated.

In the second operating mode, the viewing mode, the film 7 with the finished drawing image is also placed in the film channel 27. The capacitor 3 displaces by turning relative to the hinge attachment from the lower position to the top and together with the frame frame 28 is fixed above the film. The light source 2 is switched on and the image is projected on the screen. For the effect of movement, the film can be pulled by hand through a tape

mechanism and the screen will show the film.

The technical and economic effect of the invention lies in the fact that with one simple design you can create drawn animations and display them on the screen.
