trigger 26 and the element OR 27.

The keys 14-17, the triggers 18-21 and the time relay 22 are combined in block 8. Block 1 is designed for recording and reproducing an explanatory phonogram, text and for synchronization

the work of the film projector unit 9, overhead projector unit 10 and electrified card 6.

Generator 2 is designed to form labels recorded in block 1 when preparing a training program. The distributor 3 is used to transform the time sequence of command mark tags,

from block 1 to the space-time sequence of tags. Shaper 4 together with blocks 5 on commands coming from the distributor 3, establishes a certain

the time sequence of switching on the backlight elements of the electrified card 6.

The shaper 7, according to the commands received from the distributor 3, establishes a certain temporal sequence of operation of blocks 10 and 13. Block 13, by commands of the shaper 7, switches on the sound from block 9 and simultaneously turns off the sound from block 1. In addition, it turns off. bakes on commands from the driver 7 to turn off the sound from block 9 with simultaneous activation

soundtrack from block 1.

Block 8 is designed to control the operation of blocks 9 and 10. Block 12 is designed to control the operation of block 1, Triggers 24.26, key 23, AND 25 and OR 27 switches on and off the projection lamp of block 9 of the program of the driver 7.

When preparing a training program, you must:

prepare a movie on the selected topic;

record a phonogram of an explanatory text in the block 1, with a voiced movie you can use the phonogram of the filmV

make an entry in block 1 command labels corresponding to this learning program;

install transparencies in the cassette of the overhead projector unit 10 in the appropriate sequence;

type in the shaper 4 the sequence of switching on and off the elements of the backlight of the electrified card b;

have in the shaper 7 the sequence of operation of blocks 13 and 9,10. .

When the device is switched on according to the selected topic, the command tags from block 1 enter the distributor 3, where amplification and distribution take place along control circuits. From the corresponding outputs of the distributor 3, the command marks go to the drivers 4 and 7. From the driver 4, the command marks go to block 5 which generates commands to turn on and off the elements of the backlight of the electrified card 6. From the imaging unit 7 command marks in a certain time sequence of actions in block 8 which generates commands VK li ne and off film projector unit 9, saliva next slide in the slide projector unit 10, on and off the lamp unit 10 OHP.

The lamp of the overhead projector of the block 9 is turned on and off by the nporpciMMe generator 7. The lamp of the film projector of the block 9 is turned off from the output of the driver 7 to the single inputs of the flip-flops 20 and 21 a tape mechanism of the film projector of block 9 in the start mode. The trigger 21 also includes a relay 22 at the output of which a signal is generated that sets the trigger 21 to the zero state.

As a result, the key 17 turns off the start mode and the operating mode of the tape mechanism is activated.

In addition, this signal sets the trigger 26 to a single state, at the output of which a signal is generated, including the AND 25 element.

The signal for turning on the lamp of the projection lamp of the block 9 from the output of the imager according to the program is fed through the element 25 to the single input

trigger 24, setting it to one. At the output of the trigger 24, a signal is generated that includes the key 23, and hence the film projector lamp of the block 9.. The lamp-on signal comes from the output of the imaging unit 7 through the OR element 27 to the zero input of the trigger 24. The trigger 24 is set to the zero state, as a result of which the key 23 and the projection driver of the block 9 are turned on.

Signals of turning on the film projector of the block 8 comes from the driver 7 to the zero inputs of the flip-flops 20 and 26 and through the element OR 27 to the zero

5 trigger input 24. These triggers are set to the zero state, as a result of which both the tape mechanism and the cinema lamp of the block 9 are turned on, if the OHai has not been switched on earlier by a command from the driver 7.

The implementation of the device in the manner described above allows us to simplify the process of preparing the curriculum, expands the methodological possibilities of technical means of training, and makes it possible to create various versions of training programs.
