Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a novel card used for magic, and further development of the magic industry (which is involved in the manufacture or sale of magicians and magic tools) and the magic card. It contributes to the expansion of enjoyment.

[0002]

2. Description of the Related Art Magic has been developed in which a performer insights and applies a mark secretly decided by a customer from among a plurality of marks. One type of this magic is known to magicians as anarchy mind reading.

In this magic, a mark card having marks at each of 2 to the 5th power, that is, 32 positions (this is selected and commonly referred to as a card) and five kinds of window cards (which have holes) Known as an anarchy card because there is) and used.

As for the window card, (a) when each window card is overlaid on the mark card, 2 4 powers, that is, 16 marks can be visually recognized, and (b) each window card is inverted and overlaid on the mark card. In (a) and (a), the remaining 16 marks that could not be seen are visible, and (c) The combination of visible and invisible window cards is 1 for each mark.
A window is formed that satisfies the condition that it corresponds to pair 1. To explain the condition of (c) more specifically, for example, the mark attached to the upper left corner of the mark card is visible only in window card No. 1 and not visible in window card Nos. 2 to 5. If so, the only mark that can be seen only on No. 1 and not on other cards is the mark in the upper left corner, and there is no other mark.

This card is used as follows.
First, the performer presents the mark card to the guest and asks them to secretly determine one of the 32 marks in their mind. Next, the window cards No. 1 to No. 5 are sequentially overlaid on the mark card, and each time the customer is asked whether or not the decided mark is visible. When the answer is obtained for all the window cards, the visible window card is overlaid on the mark card, and the invisible window card is inverted and then overlaid. As a result, only the mark secretly decided by the customer will be visible, and the customer will be enchanted by a strange feeling.

Mathematically, this phenomenon can be explained as follows. FIG. 4 shows a list of phenomena that occur when the conditions (a), (b) and (c) above are satisfied. For example, the mark at position 1 cannot be visually recognized by any window card. , The mark at position 2 is visible only on window card No. 1, the mark at position 3 is visible only on window card No. 2, the mark at position 7 is only visible on window card No. 1 and No. 2. The visible relationship is illustrated. In the figure, the case where it is visible is indicated by a circle, and the case where it is not visible is indicated by a cross.

As is clear here, the types of marks and
The combination of visible window cards and invisible window cards corresponds to one-to-one correspondence, and one mark cannot be visually recognized in a combination of two or more, and one combination cannot visually recognize two or more marks. . This is because the window card complies with rule (c). Next, positions 1R to 1
6R is placed in a positional relationship that coincides with positions 1 to 16 when the card is turned over. For example, in window card No. 1, positions 2, 7, 8, 9, 10, 16R, 15R, 14R, 1
3R, 12R, 11R, 6R, 5R, 4R, 3R, 1R
The mark at the position of is visible, and if this is reversed, the remaining 2R, 7R, 8R, 9R, 10R, 16, 15,
It is shown that the marks at the positions 14, 13, 12, 11, 6, 5, 5, 4, 3, 1 can be visually recognized. This is because the window card complies with rule (b). Naturally, rule (a) is also satisfied.

Now, in this list, for example, a window card
If you can only see in No.1 and No.2 and not in No.3, No.4, or No.5, the mark that the customer has decided in his mind is the mark at position 7. is there. Here, No.3, No.
According to the No. 4 and No. 5 window cards, the mark at position 7R is commonly seen. Therefore, if this window card is inverted, the inverted position, that is, position 7 can be visually recognized. So No. 1 and No. 2 are piled up as it is (without being inverted),
When No.3, No.4 and No.5 are reversed and overlapped, only the mark at position 7 is visible. In addition, it is confirmed that the marks other than the position 7 are shielded by one of the cards and cannot be visually recognized.

[0009]

[Problems to be Solved by the Invention] This anarchy mind reading technique is a well-conceived magic technique, in which the guest wonders that a mark that he should secretly know is immediately selected, and the performer wonders. You can enjoy it together depending on how you look. However, as mentioned above, there is no leap in the logical process until the customer secretly infers the selected mark, and it is only a phenomenon that should occur naturally for a customer with mathematical ability. There is a tendency to accept that there is no mystery. Therefore, in the present invention, it is decided to create a card that can cause a more mysterious phenomenon.

[0010]

For this reason, in the present invention, the attributes of the marks attached to the mark card are classified according to the number of visible window cards in the conventional mark card. For example, in the example illustrated in FIG.
The attribute of the mark is changed between position 1 where there is no visible window card, positions 2 to 6 where there is one visible window card, and positions 7 to 16 where there are two visible window cards. Here, the attribute of the mark may be any attribute as long as it can determine which mark corresponds to the number of marks, and various meanings such as the meaning, color and shape of the mark are used. For example, if the mark of a beast is attached to the position 1, the mark of a bird is attached to the positions 2 to 6 and the mark of a fish is attached to the positions 7 to 16, the attributes are classified. Note that it is preferable that only the performer knows this attribute and that the guest cannot easily notice it.

[0011]

EXAMPLE First, 2 3 (8) marks are set to 3
An example of applying with one window card will be described. FIG. 2 shows A, B1 to B3, C1 at eight positions 1 to 4 and 4R to 1R.
Marks C to C3 and D are attached, and the relationship between each mark and the window card is displayed. Here, the mark A has zero visible window cards, the marks B1 to B3 have one visible window card, the marks C1 to C3 have two visible window cards, and the mark D is visible. There are three window cards. A, B, C and D are attributes, for example, when the mark is a mark indicating an Olympic sporting event, A is gymnastics, B is ball game (for example, B1 is volleyball, B2 is basketball, B3 is tennis), C Is athletics (C1 is marathon, C2 is 100)
m and C3 are tossed) and D is shot.

Positions 1 to 4 and 4R to 1R can be set at arbitrary positions on the card as long as the reversibility is satisfied. For example, as shown in FIG. As shown in FIG. 3 (d) (e), a matrix arrangement as shown in FIG. 3 (d) (e) or a random arrangement as shown in FIG. 3 (c) is allowed.

If the window card does not have the front and back sides, the reversibility of the window card is widely accepted. For example, as shown in FIG. 3 (a), the front and back sides can be inverted around the center line, and the diagonal line as shown in FIG. 3 (c). Invert the front and back with the center as the center, or place the 1 and 1R, 2 and 2R etc. at the place where the front and back are reversed centering on the vertical center line or the horizontal center line as shown in Fig. You can leave it.
For cards that cannot be turned upside down, make the point symmetrical about the center point as shown in Fig. 3 (b).

When performing this magic, the performer is required to remember only the relationship between the number of sheets and the attributes. The method of performing the magic is almost the same as the conventional technique, and the window card that can be visually recognized after the customer secretly determines the mark and the window card that is not visible are distinguished. In the conventional technique after sorting, the window card which cannot be visually recognized is inverted and overlapped, but this method does not do so. In this method, as a general rule, only visible cards are stacked. Figure 2
If you can see it only with the window card No.1 in, overlay only the No.1 window card on the mark card. Then, four marks at positions 2, 4R, 3R, 1R, that is, B
1, C1, C2, D are visually recognized. Therefore, the performer finds an attribute, in this case, an attribute B, in which only one window card can be visually recognized. As a result, the mark of B1 is found, so that the performer can know that the mark decided by the customer in mind is B1. Since the same phenomenon occurs for all marks, it is possible to know any mark by the same method.

At this time, even though the customer knows that one mark can be determined mathematically, he / she cannot remember the corresponding marks for all of many combinations. I feel very strange. In addition, the fact that there are no restrictions on the order in which the window cards are used actually makes it more confusing.

That is, with this card, it is not necessary to remember each of the various combinations depending on the attributes, and since the customer does not notice the logic at all, the magic of the magic is further enhanced.

Next, an example of applying the 2 <5> mark with 5 cards will be described with reference to FIG. In this example, there is a "snake" mark where the number of visible window cards is zero, and where there is one visible window card,
The first five of the twelve zodiac signs, "mouse,""cow,""tiger," and "rabbit."
"Ryu" is the window card where you can see 2 "fishes", "Taipei,""Ayu,""Abalone,""Carp,""Tuna," or "Cormorant," which is a "bird.""Duck""Ugui""Dove""crow"
Is displayed in the place where the number of visible window cards is 5, "horse"
The mark is attached. When there are three or four window cards, marks other than the above attributes are added (except for chickens, which are exceptionally treated as non-bird attributes).

The positions shown in FIG. 4 are arranged as shown in FIG. 5 on the actual card, and are arranged symmetrically when rotated by 180 ° about the center point. A prototype manufactured according to this rule is shown in Fig. 1. The actual card is composed of a mark card printed on a thick paper with business card type, and five window cards in which the opening part is cut out on the same thick paper. ing. The hole is made by combining L-shaped blades and embedding it in a wooden pattern and punching out cardboard. When 500 prototypes were made, the price per set was 200 yen or less. I was able to create it.

This card is used as follows. First, when it is visible only with one window card, the visible card is overlaid on the mark card. Window card for example
If you can see only No.1, stack only the window card No.1. Then, clearly from FIG. 4, the marks F1, G1 to G4
The marks H1 to H6, I1 to I4, and J are visible. Since only F1 has the attribute F corresponding to one sheet among them, the performer can immediately determine that it is F1 even if the table as shown in FIG. 4 is not in his head. Similarly, if it is visible only with card No. 2, it can be easily determined that it is F2, and if it is visible only with No. 3, it is F3.

Next, when visible only with two window cards, the visible window card is superposed on the mark card. For example, if you can see only two cards No.1 and No.2, you can stack No.1 and No.2. Then, clearly from FIG. 4, eight kinds of marks G1, H1, H2, H3, I1, I2 and I3 can be visually recognized. Here, the attribute corresponding to two sheets is G
Therefore, the performer can easily determine that it is G1.

As is apparent from FIG. 4, among the marks of the attribute G
Only G1 can be seen for No.1 and No.2, only G2 for No.1 and No.3, and only G3 for No.1 and No.4. Both marks can be determined by the same method. As a matter of course, the order of the window cards is not limited, and the window cards can be used in any order.

Next, the case where the three marks are visible will be described. For example, if you can see it with No.1, No.2, and No.3 window cards, overlay those window cards on the mark card. Then, four marks H1, I1, I2 and J appear. Here, since the attribute corresponding to three sheets is H, it can be determined as H1. This is exactly the same as the case of two or less sheets. However, when this method is adopted, one mark is actually determined from the four marks, and the mystery is a little poor.

Therefore, the following method is more preferable. First, superimpose the cards that were not visible, in this case No.4 and No.5 on the mark card. Then G10, H6, H9, H
Eight marks of 10, I3, I4, I5 and J appear. At this stage, the guest mistakenly thinks that the performer is trying to select a mark from the other 24 marks. The performer now looks for a mark with the attribute G of two cards as before. As a result, the mark G10 is found. Therefore, in this case, the position symmetrical to that, that is, G1
Look for the mark at position 16R, which is symmetrical to the 16 position with the 0 mark. As a result, H1 is found.

This is a method of producing a mysteriousness by utilizing the inversion property, and the mathematical process is the same as it has been so far. When you can see four cards, stack the remaining one card in the same way, find the mark of the attribute (F in this case) corresponding to one, and find the mark at this symmetrical position. Become a mark.

Even if the customer scrutinizes the mark card shown in FIG. 1, there is almost no danger of realizing that the mark is classified according to the attribute. The higher the customer's mathematical ability, the more mysterious that is. It will be impressive.

The above principle can be practically used when n is 3 or more. As shown in FIG. 6, when the number of window cards is 6, 64 marks are used, and when 7 windows are used, 128 marks are used. It becomes possible to let the customer choose from among them. As the number of cards increases, it is unlikely that the combination of cards that the performer can see and cards that the performer cannot see is stored in association with the marks, and the mystery becomes even more remarkable.

[0027]

According to the present invention, since no technique is used, anyone can play this magic, and also can play the magic of high logicality. As a result, it stimulates the intellectual curiosity of the guests and makes Magic even more interesting. For this reason, this card is often used and can contribute to the development of the magic industry involved in the manufacture and sale of magic items.
