Description

[Detailed description of the invention] The present invention relates to a card matching learning tool that can automatically determine whether a placed card is correct or incorrect by using a combination of magnetic polarities, and is particularly useful for use by young children to increase their learning motivation. It was designed so that it could be done.

(Technical background of the invention and its problems) The present applicant has developed and proposed a card matching learning device equipped with a display circuit that is activated when all answer cards are answered correctly (Utility Application No. 43034/1983). . In this method, a display answer such as a voice generator is activated only when all answer cards are correct, and it is not possible to determine whether each individual card is correct or incorrect. Therefore, if the correct answer cannot be displayed, the answerer has to rearrange all the cards without knowing which card has an incorrect answer. Therefore, if this is used by young children, it would be a good idea to learn the knowledge about the questions beforehand, or if an older person is nearby, but it will be difficult to get them to answer all the cards correctly, and they will not be able to answer them halfway. There were inconveniences that could cause students to lose their desire to learn and stop or abandon their work.

(Structure of the invention) The structure of the invention consists of a single question sheet in which a plurality of sections of a fixed shape are formed and a question is displayed in each section, an answer card placed on the section, and the question sheet. A plurality of areas are provided in the base plate corresponding to the sections of the question sheet, and a plurality of magnet pieces are provided at predetermined corresponding positions in each area and the answer card. The magnetic poles are assembled so that the buried answer card is attracted to the correct answer position and repelled to the incorrect answer position, and is closed by adsorption of the answer card that has been answered correctly on the base plate in each area. In addition to providing a switch for
When each of the switches is closed, a light emitting diode is built in corresponding to the area of each answer card, and each set of each of the switches and each of the light emitting diodes is connected in parallel to a power source, and each answer card is connected in parallel to a power source. When a correct answer is given, the corresponding light emitting diode is turned on, and it is possible to immediately determine whether each card is correct or incorrect.

In addition, since the light emitting diodes used in this project are all the same, it is possible to use a display device such as an audio device by providing an appropriate judgment circuit based on the current value of the circuit or the combined resistance value when all the answers are correct. It is also easy to get the correct answer displayed twice.

(Example) An embodiment shown in the drawings will be described below.

1 is a synthetic resin underframe, 2 is a base plate, and 3 is an edge.

A region 4 corresponding to the size of the card is formed on the surface 2a of the base plate 2, and a fixed number (for example, three) of magnet pieces 5 are embedded in each region with the polarities of the magnets combined. ing.

Reference numeral 6 is a question sheet, in which question 8 is displayed in a card placement section 7 having the same shape as area 4.

9 is a plurality of sheets 1 having the same size as section 7;
A set of answer cards, in which answer 11 is displayed on the surface of each card, and two magnet pieces 10 are located at positions corresponding to the buried positions of the magnets in the base plate, and their corresponding magnetic poles do not repel, respectively. They are buried in such combinations.

Each area of the base plate 2 is provided with a switch contact 20 and a switch operating piece 21 for a movable contact, the actuating piece projecting slightly above the base plate. 23 is a light emitting diode that emits light when the corresponding switch is closed, and is connected in parallel to the power supply 22 with each switch 20, and is fixed to the surface of the base plate edge 3 adjacent to and corresponding to each area 4 of each answer card. has been done.

Next, we will explain how to use this product.

A question sheet 6 is placed on one side 2a of the base plate 2 of the underframe. When the six answer cards 9 shown in FIG. Since the facing magnetic poles of -2 are different, they are attracted to each other, so the actuating piece 21 is pushed down and the switch contact 20 is closed. When the switch is closed, the light emitting diodes 23 located at the positions corresponding to the respective cards are individually illuminated, and it is immediately determined that the answer is correct. On the other hand, if the wrong card is placed, at least one magnet will repel it, causing the card to float, the contact 20 will not close, and the light emitting diode will not light up, so the answer is incorrect. Once you know this, you can re-place another card and get the correct answer.

Although the above embodiment is an example in which the number of magnets in each area of the base plate is three, it is not limited to this, and for example, by increasing the number of magnets, the number of cards can be increased. Therefore, even more difficult problems or games are possible.

(Effects of the invention) Since the present invention has the above-mentioned configuration, when each answer card is answered correctly, the corresponding light emitting diode is lit and the correctness or incorrectness of each card is immediately determined, which increases the learning motivation of children and others. It is suitable as a learning material because it has the effect of increasing students' ability to understand the problem, and even if they have not learned the knowledge of the problem beforehand or an elder is not around, they can reliably get the correct answer by changing the combination of cards. It is something to do.
