Abstract

SUMMARY OF THE INVENTION: the device comprises a housing with a data card receiver. In the lower part of the receiver there are two elastic plates cantilevered in the housing. The free end of one plate is made in the form of a bracket with the contacts of bulbs fixed to it. Between the contacts of the bulbs there is a middle contact fixed to the free end of the second elastic plate having a pin. Each of the cards has cutouts on one of its edges for engaging with the pin. Cutout depth not less than the sum of the gaps between the contacts. The pin is mounted in a console, so that its end is located from the upper bracket flange at a distance corresponding to the gap between the middle and lower contacts. Bill.

The invention relates to technical means of training and can be used to control (mainly for self-control) knowledge, for example, according to the rules of the road.

A device for monitoring the knowledge of students is known, comprising an album of cassettes and an indication unit / wherein the album cassette frames are equipped with windows, two metal plates fixed inside the cassette on its opposite sides, between which a control card with a cutout in the area corresponding to the correct answer number is placed and a metal contact plate.

A device for self-monitoring students' knowledge is also known, which contains a sequentially arranged board with a main contact, a punch card and a blank, as well as an elastic base plate with an additional contact installed against the main contact, one end of which is rigidly fixed to the bottom surface of the board, and the other rests on its punch card, and an additional group of contacts installed in the case under the card, the lower of the contacts of the additional group is rigidly connected to the body, and the upper - es elastic plate, wherein the circuit board with the contact and card osnsznym cantilevered to the chassis.

The closest in purpose and technical essence of the present invention is a device for controlling students' knowledge (prototype), containing a set of cards with the question text and options for encoded answers, a rotary disk for entering code information, combining -h

associated with an index located on the housing, and the light signaling unit of the correct answer with two light bulbs of different colors, the rotary disk having two transparent shells on its rim for placing cards between them, and the light signaling unit contains a spring-loaded button with a contact connected to the circuit one of the bulbs, and a movable pin located in the button with a conductive plate having two contacts, one of which is designed to interact with the button contact, and the second with the contact mounted on the truncated and associated with the second lamp, wherein the housing has an opening for inserting the pin, and a disc - a number of openings superposed at a predetermined position in the housing bore.

The purpose of the invention is to improve ease of use.

The invention and its distinguishing features (from the prototype) are that the device has an additional elastic plate, the end of which is made in the form of a bracket, and the contacts of the bulbs are mounted on the bracket one under the other, the housing has a card receiver with a groove, the plates are located at the bottom the receiver and are cantilevered in the case so that the elastic plate with the middle contact is located in the same plane as the bottom of the receiver, each card has cutouts on one of its edges designed for operating with a pin, and the installation risk, a perpendicular edge with cutouts, the depth of which is not less than the sum of the gaps between the contacts, while the pin is cantilevered on the plate so that its end face is located from the top shelf of the bracket at a distance corresponding to the size of the gap between the middle the contact and the lower contact of the bulb, and numbered divisions are applied to the housing at the receiver groove.

In FIG. 1 shows a device for monitoring knowledge (from the side of the light signaling windows of the correctness of the answer) with a cutout of a part of the housing cover; in FIG. 2 is a section AA in FIG. 1; in FIG. 3 is a view along arrow B in FIG. 1; in FIG. 4 shows a variant of the mutual arrangement of plates and contacts with an electric circuit for contacting contacts with light bulbs for indicating the result of a response; in FIG. 5 is an example of the location of coding cutouts on a card.

The knowledge control device comprises a housing 1 (Fig. 1). a cover 2 (Fig. 2) with a window 3 for accommodating a set of 4 information cards and two windows 5 for light bulbs b and 7 of a light signaling of the correct answer. There is a groove 8 of the card receiver between the housing 1 and the cover 2, the end face a of the elastic wall of the groove being oval for convenience of installing the card and adjoining the cover practically without any gap. On the front surface of the device at the groove 8 there are five divisions,

numbered 1-5 (Fig. 3). In the lower part of the groove 8, two elastic plates 9 and 10 are cantilevered in the housing 1 (Fig. 4), while the free end of the plate 10 is made in the form of a bracket in with contacts 11 and 12 fixed to it one under the other, between which it is placed with gaps the middle contact 13, mounted on the free end of the plate 9, on which the pin 14 is cantilevered in such a way

that its end face is located from the upper flange of the bracket c at a distance corresponding to the gap between the middle contact 13 and the lower contact 12. In the free state, the plate 9 with the middle contact

13 is located in the same plane with the bottom of the receiver (groove 8) cards. Each card 15 (Fig. 5) has cutouts d on one of its edges and an installation risk o, a perpendicular edge with cutouts, the depth of which is not less than the sum of the gaps between the contacts 12,13 and 11 (Fig. 4). The device has a power cell 16,

The procedure for working with the device for controlling knowledge is as follows. Take device

in the left hand with windows 5 (Fig. 1) to itself. With your right hand moving away from windows 5 the entire set of information cards in the rectangular window 3, remove the upper edge of the cards from the housing 1. Remove one card from the kit and install the rest into the housing. Read the question on the card, select the number of the correct answer and insert it with the edge having cutouts in the groove 8 (Fig. 2ji 3) of the card receiver until it stops in

its bottom so that in this case the installation risk o (Fig. 5) of card 15 coincides with the division applied to the end of the housing cover having a number corresponding to the number of the selected answer.

If the answer is correct, the green light will turn on, and if the answer is incorrect, red. Only in the case of a correctly selected answer the corresponding coding cut d of the card will coincide with the pin 14 (Fig. 4), therefore

the card will not act on the pin with its edge, but will move the bracket from the bottom with its edge, as a result of which contacts 11 and 13 will be closed, the green light 6. will turn on. And if the answer is incorrect, not a single one

from the cutouts d (FIG. 5) of the card 15 will not be

Claims (1)

coincide with the pin 14 (Fig. 4), so the card will move the pin 14 with its edge down along with the free end of the elastic plate 9, as a result of which the contacts 13 and 12 are closed, the red bulb 7 will light up.
