Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is particularly applicable to games such as shogi and chess (Western shogi), in which three or more types of pieces are used. The present invention relates to a game device having a function of detecting.

Structure of conventional examples and their problems In recent years, there has been a growing demand for automatic recording of game scores in games such as Go, Shogi, Chess, and Othello, which can be used for later learning.

At that time, it goes without saying that it is necessary to detect the placement of pieces and Go stones.In Go games, it is already difficult to detect the placement of stones because there are only a few types of stones and the stones have many directions. It is relatively easy to do. As shown in Fig. 1, the magnetic body 2 is embedded in Go stones 1 made of plastic and Suchinoku so that the magnetization direction of the magnetic body 20 is perpendicular to the game board. By reversing the position, the magnetic sensing element 4 arranged under the game board 3 detects the magnetic field.

However, in games such as shogi or chess, where there are many types of pieces and the pieces have different directions and heads and tails, the above method has limitations.

OBJECTS OF THE INVENTION The present invention relates to a game device including a game board and pieces having a function of detecting the positions, types, and directions of pieces in games such as shogi and chess that use three or more types of pieces.

Structure of the Invention The game device of the present invention is a game device that uses pieces (or Go stones) and a game board, and includes pieces in which at least one magnetic material having a uniform magnetic strength is embedded corresponding to the type of pieces and a magnetic head. A game comprising a signal processing circuit that detects the type, position, and direction of the pieces by sweeping the board with a magnetic field array arranged at the bottom of each square on the board. It consists of a board, which makes it possible to easily detect the type, direction, and position of the pieces even when there are many types of pieces.

DESCRIPTION OF EMBODIMENTS FIG. 2 shows a cross-sectional view of shogi pieces in an embodiment of the present invention as viewed from the game board side. A required number of long rectangular bar-shaped magnetic bodies (permanent magnets) 11 having uniform magnetic strength are buried according to the 120 types of pieces. The magnetic material 11 is buried so that its longitudinal direction is parallel to the surface of the piece, and the direction of magnetization is as follows.
Preferably, it is perpendicular to the longitudinal direction. The reason for using the long magnetic material 11 magnetized in this way is that during the game, the pieces are not always placed in the middle of the squares, so they may be slightly shifted or placed diagonally. This is to ensure accurate placement detection.

3(a) and (1)) show cross-sectional views taken along lines A-A and B-B in FIG. 2, respectively. As with actual shogi pieces 21, if the pieces have different front and back sides, a different number of magnetic bodies 22 will be embedded in each side. A magnetic head array can be used to detect the types, directions, and positions of pieces on the game board. FIG. 4 is a vertical sectional view of a game board according to an embodiment of the present invention and a number of pieces placed on the board as seen from the player's side. A magnetic head array A consisting of magnetic nozzles 42 arranged in the game board 41 to obtain piece information from each square is brought close to the back of the board, and each time a player makes a move, the magnetic head array A is The step motor 43 is driven to make the Herad array A slide on the back surface 44 of the large No. 1. By doing this, an electrical signal corresponding to the arrangement of the magnetic materials embedded in the pieces 45 on the board can be extracted, and by circuit processing this, information such as the type, direction, and position of the piece can be obtained.

FIG. 6 is a diagram showing the state of the magnetic head output assuming various cases regarding the mutual positions of the pieces and the squares. However, in this case, the number of magnetic bodies present on the side of the piece sensed by the magnetic head is five.

In Fig. 6←), the center position C of the piece placed in the square coincides with the center C' of the square, and moreover, the magnetization direction of the magnetic material in the piece coincides with the moving direction L' of the magnetic head. This is the case.

FIG. 6(b) shows a case where L' matches that shown in "7", but C and CI match, but are shifted by tl when converted to the chair time axis.

Similarly, in FIG. 6(C), L and L' match, but C and C' match, but are shifted by t2 when converted to the chair time axis.

FIG. 6(d) shows a case where C and C' match, but L and Ll do not match, and the signal period T3 is shown in FIG.
), and the time difference T between the negative direction signal N and the positive direction signal P is also slightly larger than the signal period T1 in FIG.
Time difference T2 in a). It is slightly larger than that, but both are small.

Although not shown, almost the same situation occurs when both C and C' and L and L' do not match.In either case, the time pitch starting from the first signal is within that time pitch. It is easily possible to detect a certain signal.

Next, an example of a method for obtaining information regarding pieces placed in a square will be explained using FIG. 7.

In Fig. 7, an identification signal x is placed between the sign signalman and ■b.
,y,z exist. Let's now temporarily define it as follows.

If a positive direction signal is read after a negative direction signal, it is 1°.If a negative direction signal follows a positive direction signal, it is 2°.If neither signal is present, it is O.If defined in this way, the magnetic head output is as shown in In case (a), it has 5-digit ternary information "11201".

If you extract the identification signal part from this, it will be "120" 3
It is a 3-digit value in decimal. Since there are three identification signals, x, y, and z, 3-27 can be distinguished.

FIG. 7(b) shows a case where the same type of pieces as in FIG. 7(a) K are placed in the opposite direction, and the magnetic head output is reversed on the time axis. According to the above definition, the head output in this case has the information "20122".

Since the sign signals a and b are 11211, it can be determined that the pieces are in the opposite direction. Furthermore, if it is determined that the piece is in the opposite direction, the following two processes are performed regarding the information obtained from the identification signal, such as the above-mentioned "012".

(1) Swap "2" and "1".

(2) Reverse the arrangement of the three-digit information.

Through the above two processes, it is determined that the identification signal indicates "120", and it becomes possible to determine that the piece is the same type as in the case of FIG. 7(,).

Note that the above-mentioned 6 definitions'' and ``processes'' can be realized using conventional techniques, and their explanations will be omitted.

In the above example, two label magnetic bodies are required to obtain a label signal, and zero to three identification magnetic bodies at maximum are required to obtain an identification signal. Therefore, there are a maximum of five in total.

In addition to making it possible to distinguish the direction of the pieces as described above, the marking magnetic material also contributes to indicating the effective area of the information given to the pieces.

The identification signal is not differentiated into three values of 2"ff11Z'"0",
A method of distinguishing into two values of +111ZII○'' corresponding to presence or absence is also considered, but this is disadvantageous when it is necessary to increase the number of identification magnetic bodies.

FIG. 6 shows a block diagram of the game device of the present invention, in which the type and direction of pieces 52 on the board are changed by sweeping the magnetic head array disposed inside the game board 51. ,
A position-related signal is processed by an electric circuit 53, and can be recorded and stored in a recording device 54 such as a magnetic card, tape, or semiconductor memory, and a regenerator 55 as necessary.
can be played with.

Effects of the Invention As is clear from the above explanation, the game device of the present invention is a game device that uses pieces (or stones) and a game board, and has at least one or more magnetic intensities that are uniform in accordance with the types of pieces. A signal processing circuit that detects the type, position, and direction of the pieces by sweeping the board surface with a magnetic torsion array consisting of pieces embedded with magnetic material and magnetic heads arranged below each square on the board surface. It consists of a game board equipped with a game board, which can accurately and automatically record the progress of a game, and can later be used to learn the direction of the game while playing back. Also, during the game,
Since information about the placement of pieces that changes every time can be retrieved without the need for human intervention, there is no need for the recorder to take the trouble of visually transcribing the score, and as a result, it is convenient because it does not interfere with consideration of the players during the game. .
