Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to provide a game device suitable for application to Go, Shogi, etc., for example.

Most of the conventional devices that can automatically record the game records of Go, Shogi, Chess, etc. require separate entry of starting coordinates using a switch, etc., which is cumbersome to operate and prone to operational errors. However, the drawback was that the original interest in the game was lost.

One of the reasons for inputting moves using switch operations is that in games such as Go and Shogi, there is a rule that allows you to change the starting position as long as you do not take your finger off the Go stones (or pieces). Because there was a rule that allowed ``Karauchi'', it was impossible to accurately record the game just by checking the presence or absence of Go stones (or pieces) on the board.

The present invention aims to provide a game device that can automatically obtain an accurate score just by operating the pieces (or Go stones) on the board, by having the function of identifying the above-mentioned Kara-uchi and regular moves. For example, in shogi, a piece that was at point A (x ₀ , y ₀ ) is moved from point B (x ₁ , y ₁ ) to C (x ₂ ,
When the piece is placed at point y ₂ ), the conventional device picks up the piece at point A (x ₀ , y ₀ ), moves to point B (x ₁ , y ₁ ), and places the piece at point B (x ₁ , y ₁ ). However, if the device of the present invention is used, it will be possible to accurately detect ``take a piece at point A (x 0 , y ₀ ) and move to point C (x _{0 ,} y ₀ )''.
This makes it possible to detect "starting at point (x ₂ , y ₂ )".

The first feature of the present invention is to focus on the fact that Karauchi and regular moves are made consecutively with the same piece, and when a move is detected, the piece used is the same as the piece used before. It is a way to deal with empty play by checking whether they are the same or not, and invalidating the previous move if they are the same.

However, even in shogi, there are dozens of pieces, and it is not easy to distinguish them all.

The second feature of the present invention is to focus on the fact that Karauchi and regular moves are temporally consecutive, and when a move is detected, it is checked whether a piece remains at the location where the move was made immediately before. If there are no pieces, the currently detected move is determined to be on the same piece as the previous move, and the previous move is invalidated as a empty move.

Hereinafter, details of the present invention will be explained with reference to the drawings.

FIG. 1 shows a schematic configuration when the present invention is applied to Go, where 1 is a game board and 2 is a Go stone, which corresponds to the pieces referred to in the claims. 3 is a move detection means, 4 is a game record recording means, and 5 is a piece identification means.

An example of Go stones 2 is shown in FIG. In FIG. 2, 20 is a so-called external object made of plastic or the like, and has a permanent magnet 21 built therein.

FIG. 3 is a partial diagram showing the arrangement of the sensors 10 provided directly below the Go stone starting points on the game board 1, and there are 361 sensors in total on the board. A saturable magnetic core (not shown) is used at the center of the sensor 10, and this saturable magnetic core is connected to a permanent magnet 2 built in the Go stone 2.
1 is close to each other, the magnetic permeability becomes extremely small due to the magnetic field.

FIG. 4 is a circuit block diagram showing one embodiment of the present invention. In FIG. 4, 11 is a sensor 10
12 is a primary winding, and 12 is a secondary winding, which are provided on the above-mentioned saturable magnetic core.

In the start detecting means 3, an oscillator 30 excites the primary winding 11 of the sensor 10, and its state is switched by a primary winding switching decoder circuit 31. Further, the output of the secondary winding 12 is switched by a secondary winding switching decoder circuit 32 and is converted into a binary value.

Further, since the primary winding switching decoder circuit 31 and the secondary winding switching decoder circuit 32 are switched based on the address given by the control circuit 35, the output of the secondary winding switching decoder circuit 32 is
When Go stone 2 does not exist at the starting point on the game board 1 corresponding to the address given by , a high level output is obtained based on the large amplitude signal obtained in the secondary winding 12, and Go stone 2 is present. Sometimes, due to the reduced permeability of the saturable magnetic core, the amplitude of the signal available at the secondary winding 12 is reduced, resulting in a low level output.

The board state recording circuit 33 transfers the data stored at the address given by the control circuit 35 to the comparison circuit 34.
The comparator circuit 34 outputs the output from the secondary winding switching decoder circuit 32 and the board state recording circuit 3.
3, and when they do not match, the output is sent to the control circuit 35. The control circuit 35 rewrites the data in the board state recording circuit 33 so that the comparison in the comparison circuit 34 matches, and continues to change the addresses to be sequentially output.

Therefore, since the contents of the board state recording circuit 33 are normally controlled to match the state of the game board 1, the comparison circuit 34 indicates that there is a new start or a missing stone on the game board 1. The output will be obtained only when That is, the start detection means 3
is a board change detection signal output from the comparator circuit 34, an address output from the control circuit 35, and a starting point on the game board 1 corresponding to the address when a new start or a new move occurs on the game board 1. The output of the secondary winding switching decoder circuit 32 which gives the presence or absence of the Go stones 2 at is sent out.

When the piece identification means 5 receives the board surface change detection signal from the move detection means 3, the piece identification means 5 activates the secondary winding switching decoder circuit 3.
2 is checked, and when it is at a high level, that is, there is a Go stone 2 on the game board 1, it is assumed that a move has been made, and the address data given by the move detecting means 3 is written into the first register 40 of the game record recording means 4. At the same time, the address data recorded in the second register 41 is given to the control circuit 35 of the start detecting means 3, and by controlling this, the game corresponding to the address recorded in the second register 41 is executed. The secondary winding switching decoder circuit 32 of the move detection means detects the presence or absence of a Go stone at the start point on the board 1.
This is obtained as the output of the game score recording means 4, and when there is a low level, that is, 2 Go stones, the address of the game record recording means 4 is
After incrementing the address of the counter 42, the contents of the first register 40 are recorded in the second register 41 and the game record recording circuit 43, and the output of the secondary winding switching register circuit 32 is at a high level, that is, there are no Go stones. At times, the first register 4 is updated while maintaining the address of the address counter 42 of the game record recording means 4.
The contents of 0 are transferred to the second register 41 and the game record recording circuit 4.
Record in 3. Here, the control circuit 35, the primary winding switching decoder circuit 31, and the secondary winding switching decoder circuit 32 constitute a piece presence/absence determination circuit as referred to in claim 2.

By sequentially repeating the above-described procedure based on the output of the move detecting means 3, the correct game score will be recorded in the game score recording means 4 one after another.

At the start of the game, the contents of the board state recording circuit 33, the first register 40, the second register 41, and the game score recording circuit 43 are cleared using a switch or the like (not shown), and the address and
It is also necessary to reset the counter 42.

As described above, according to the present invention, the player can simply play the game in the same way as a traditional game, without having to make any unnecessary switch operations or worrying about the game record being disturbed by playing from scratch, etc. A game device that can obtain accurate game records can be realized, and its utility value is extremely large.

The above explanation was about Go, but
The same can be applied to Chess, and the same can be applied to Shogi by giving an address to the piece stand on which the captured piece is placed in the same way as the starting point on the game board, and filling in the sensor.

Further, the means for detecting Go stones is not limited to the method using magnetic coupling shown in the embodiments, and it goes without saying that the present invention can also be implemented using optical methods.
