Description

[Detailed description of the invention] This invention relates to a card matching learning tool, and is capable of automatically determining whether a placed card is correct or incorrect by utilizing the polarity of a magnet.

Card alignment itself is well known, but conventionally, it has been common to determine whether or not the card sequence is correct based on the continuity of the printed screen displayed on the back side of the card.

This method has the inconvenience of having to use a mounting table with a transparent back surface, place the card on it, and turn it over to check the printed screen on the back surface.

The present invention consists of a set of multiple cards, a question sheet on which the cards are fixed, and a base on which the question sheet is placed, and magnetic poles are provided on each upper and lower surface in the base and the card. Multiple pieces of magnets for determining correctness are embedded in corresponding predetermined positions, and if the answer is wrong, the card will be repelled, and if the answer is correct, the card will be attracted, and when the card is attracted, each card will be placed separately. The answer display device is operated by the operation of a magnet and a magnetic sensing reed switch disposed in the base, and the learning tool device is made smaller and lighter.

The embodiments shown in the drawings will be described below.

1 is a base made of synthetic resin, cardboard, etc. in the shape of a case; 2 is a sheet placing portion formed by recessing a part of the upper surface of the base 1; and 3 is an edge.

A region 4 corresponding to the size of the card is formed on the surface 2a of the sheet placement section 2, and a certain number (for example, two) of magnet pieces 5 for determining correctness are arranged in each region as magnets for answer cards, which will be described later. and its polarity are combined and buried.

Reference numeral 6 is a question sheet, and 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 the two magnet pieces 10 for determining correctness are located at positions corresponding to the buried positions of the magnets in the base, and their corresponding magnetic poles are respectively They are buried in a combination that will not cause repulsion.

Reference numeral 12 denotes a switch closing magnet piece buried at a different position from the magnet piece 10 for determining whether the card is correct or incorrect. Reference numeral 13 denotes a reed switch installed vertically in the base 1 directly below the switch closing magnet piece 12, and is closed by the magnetic action of the switch closing magnet piece on the answer card. . Each reed switch 13 has its terminals 13a and 13b connected to each substrate 14 and 15 so that it is held upright between the substrates 14 and 15 disposed at the middle and bottom of the base 1. It passes through and is bent at a right angle and connected to each board 14, 15 by connection 16, 17. These reed switches 13 are connected in series to an answer display section 18 having display means such as a melody IC and a lamp.

Next, we will explain how to use this product.

A question sheet 6 is placed on the sheet placing portion 2 of the board 1. When the six answer cards 9 in FIG. -2 The facing magnetic poles are different, so they are attracted to each other, and the cards are placed in each section 7 of the question sheet.
placed on top. When the card is placed in place, the reed switch 13 immediately below it is closed by the magnetic action of the switch-closing magnet piece 12 of the card. On the other hand, if (another card) is placed by mistake, at least one pair of opposing magnet pieces will repel, causing the card to float and not stay in place, causing the card's switch closing magnet piece to repel. The magnetic effect does not affect the reed switch.

When all the cards placed on each area 7 are correct in this way, all read switches 1
3 is closed, the display circuit is activated, and the answer display section 18 automatically and immediately displays that the answer is correct, so the answerer does not have to worry about deciding whether the answer is correct or incorrect.

The above embodiment is an example in which the number of magnets for determining correctness of each area 7 and each answer card 9 of the question sheet is two, but by increasing the number of magnets, the number of cards can be increased. Even more difficult problems or games become possible.

Furthermore, in this case, the cards can also be used with answers displayed on their backs, so two problem sheets can be applied to one set of cards.
