FIELD: training. ^ SUBSTANCE: device contains stands of the testee and the investigator each of which contains an Lighted Electronic Display with switches panel where transparent and flexible transparencies are put on, for the testee and the investigator, respectively, while the transparencies are chequered, the number and area of each sector is equal to the number and area of the indicators-switches, on the surfaces of sectors of the testee and the investigator inscriptions are written, respectively, the questions and alternative responses, in addition, it contains electronic blocks of the testee and the investigator where the indicators-switches are placed, in the investigator's block they are connected with one side to a power source, and with another - to a group of indicators-switches of the testee's block, to the input of the electrical timer starting and to one input of coincidence circuit, located in the testee's block whose output is connected with the indicator of the correct answer, one of the indicators-switches of each group of the transparency of the testee is located under the transparency sector with the correct answer, it connected to the second input of the coincidence circuit with input of the electrical timer shutdown, and through the diode and the impulse counter with number of impulses display showing the number of responses of the testee, the indicator-switch is structurally made as one block, in the investigator's block it represents a circuit of the light indicator and a switch connected in series, and in a block of the testee they are connected in parallel and are connected with one output to the investigator's block. ^ EFFECT: simplification and cheapening of the device. ^ 5 dwg |
