Description of the Related Art As a conventional competition watch of this type, for example, when one of the competitors starts a competition, the time display section of the other competitor is activated and a predetermined timepiece is held. The time is sequentially subtracted, and after this one competitor points to the piece, pressing the switch on the one time display unit side of the competition clock stops the subtraction of this one time display unit, and at the same time, The subtraction of the time display of the other competitor is started, and the other competitor points his hand and presses the switch of the other time display to reduce the time of the other time display. It stops, and the subtraction of the time display section of the one competitor starts.

[0003]

However, in such a conventional apparatus, since the competitor must press the switch each time, if the player is engrossed in the competition, he or she may forget to press it. In addition, the switch operation itself was troublesome.

Accordingly, an object of the present invention is to provide a competition clock which can automatically display the time of each competitor on each time display section without the competitor pressing the switch each time.

[0005]

Means for Solving the Problems In order to achieve such a problem, the invention according to claim 1 is used for a game such as shogi, go, chess, etc., in which one-on-one alternately points to pieces, etc. It has two time display sections for displaying, and both time display sections are provided corresponding to both athletes, and the time display section for one athlete displays one time after the other athlete points. A competition timepiece that displays the time required for a player to point to a piece or the like by subtracting it from a predetermined time, and a detecting unit that detects that the competitor points to the piece or the like; When detecting that the pointing is performed, the control unit that stops the subtraction of the time display unit of the one athlete side from the signal from the detection unit and starts the subtraction of the time display unit of the other athlete. It is characterized by having a competition clock having.

According to this configuration, when one of the competitors (the first player) points to a piece or the like after the start of the competition, this state is detected by the detection unit, and a signal from the detection unit detects the state.
The subtraction of the time display portion on the leading side is stopped, and the subtraction of the time display portion of the other competitor (rear hand) is started. Then, this time, when the back hand points to a piece or the like, this state is detected by the detection unit, and the signal from this detection unit stops the subtraction of the time display unit on the back side, and the subtraction of the time display unit on the front side. Is started. As described above, since each competitor simply points to the piece or the like, the time display section of each competitor is automatically subtracted, so that the competitor does not need to press the switch as in the past,
You can concentrate on the competition without forgetting to press the switch.

According to a second aspect of the present invention, the detecting section detects a vibration generated on a game board such as a shogi board, a go board or a chess board when the player points at a piece or the like. Then, the detection signal is transmitted to the control unit.

According to this configuration, when the competitor points at the piece or the like, vibration occurs in the game board, so that by using this vibration, it is possible to easily detect that the competitor points at the piece. .

According to a third aspect of the present invention, the detection unit according to the first aspect is configured to generate a sound generated on a shogi board, a go board, a chess board or the like when a player points at a piece or the like. It is characterized by detecting and transmitting the detection signal to the control unit.

[0010] According to this configuration, when the competitor points at the piece or the like, a sound is generated between the competitor and the game board. If this sound is used, it is easy for the competitor to point at the piece or the like. Can be detected.

The invention according to claim 4 is the invention according to claim 2 or 3.
The control unit according to the above, when a plurality of detection signals from the detection unit is transmitted within a predetermined time, to determine these as one signal, to stop the subtraction of the time display unit of one athlete side,
The time display section of the other competitor is set to start subtraction.

According to such a configuration, during a competition, an illegal vibration such as a release of the hand pointing at a piece, a stone, or the like or a re-hit may occur. A detection signal is transmitted. However, even when a plurality of detection signals are transmitted within a predetermined period of time, the control unit determines that these are one signal, thereby preventing malfunction. Of course, the predetermined time must be set appropriately in consideration of the time indicating the competitor's piece or the like.

[0013]

Embodiments of the present invention will be described below.

1 to 5 show an embodiment of the present invention.

First, the structure will be described. In FIG. 3, reference numeral 1 denotes a competition watch. This watch 1 is composed of a watch main body 2 and a piezoelectric sensor 3 as a “detection section” mounted on the back side of the shogi board 4. It is composed of

The piezoelectric sensor 3 detects a vibration of the shogi board 4 generated when the player points at a piece, and sends a signal to the timepiece main body 2.

The timepiece body 2 amplifies the signal from the piezoelectric sensor 3 by an amplifier 5 and compares the signal from the amplifier 5 (see FIG. 4A) with a constant voltage b by a voltage comparator 6. Then, a minute signal is removed, and the signal is converted into a digital signal (see FIG. 4B). The constant voltage b is appropriately selected so as to remove minute vibrations and illegal vibrations (such as vibrations when the shogi board 4 is touched by hand). Next, when a plurality of pulse signals from the voltage comparator 6 are transmitted within the predetermined time c by the illegal signal removal circuit 7, these are output as one pulse signal ((c in FIG. 4). )reference).

When this pulse signal (see FIG. 5 (a)) is inputted to the switch switching circuit 8, when the first pulse signal P1 is inputted, as shown in FIG. 5 (b). When the first switch ON signal S1 is output and the second pulse signal P2 is input, the second switch ON signal S2 is output, and when the third pulse signal P3 is input. , A switch ON signal S3 on the leading side is output.

The switch ON signals S1 are input to the competition clock unit 9, for example, as shown in FIG.
When the first switch ON signal S1 is input to the switch 9a, this signal is input to the CPU 9c, and the signal from the CPU 9c stops the subtraction of the first time display unit 10 in the time table. The subtraction of the time table on the time display unit 11 is started. At the same time, the lower count display 12 of the time table of the rear time display section 11 blinks. Next, the switch ON signal S2 on the rear side is
b, the CPU 9c reverses the above,
The subtraction of the time table of the time display unit 11 on the rear side is stopped,
The subtraction of the time table on the time display unit 10 on the leading side is started. At the same time, the lower count display 13 of the time table of the time display unit 10 on the leading side blinks.

The competition clock unit 9 has a structure shown in FIG.
As shown in the figure, a pair of start buttons 1 on the front side and the rear side
The start button 14 is connected to the switch 9a in FIG. 2, and the start button 15 is connected to the switch 9b. When these buttons 14 and 15 are pressed, the respective switches 9a and 9b are turned on. It is supposed to be.

Next, the operation will be described.

First, the setting time is set by operating the setting key 16 shown in FIG. If the rear side of the start buttons 14 and 15 is the start button 14, this button 14
The game is started by pressing. As a result, the switch 9b is turned ON, the time table of the time display unit 10 on the leading side is subtracted from the remaining time via the CPU 9c, and the number display 13 below this blinks.

Then, the first competitor starts, that is,
When the player points to a piece, the shogi board 4 vibrates. This vibration is detected by the piezoelectric sensor 3 and the analog waveform (10 mV to 1
(About 00 mV) is detected by the amplifier 5 of the controller 17
The signal is amplified to about V, and a signal as shown in FIG. Then, the voltage is compared with a constant voltage b by the voltage comparator 6 to remove minute vibrations, and is converted into a digital signal.
The signal as shown in FIG.

In the illegal signal removing circuit 7, a predetermined time c
Even if a plurality of digital signals are input during this period, the digital signals are output to the switch switching circuit 8 as one digital signal.
In the case of this example, as shown in FIG. 4B, since two digital signals D1 and D2 are input during the fixed time c, the digital signal D2 is ignored and the illegal signal removal circuit 7 Thus, one digital signal as shown in FIG. 4C is output to the switch switching circuit 8. In this way, malfunction can be prevented even when an illegal vibration occurs, such as when pointing and releasing the piece or re-pointing the piece. As the fixed time c, it is necessary to appropriately select a time at which such irregular vibration will occur.

When the first pulse signal P1 is input from the unauthorized signal removing circuit 7 to the switch switching circuit 8, the switch ON signal S1 on the leading side is input from the switch switching circuit 8 to the switch 9a. . Then, CPU
While the subtraction of the time display of the time display unit 10 on the leading side is stopped via 9c, the time display of the time display unit 11 on the back side is subtracted, and the count display 12 is displayed below the time display unit 11. Flashes.

Thereafter, when the rear competitor starts, a switch ON signal S2 on the rear side is output from the switch switching circuit 8 by the same operation as described above, and the time display on the time display section 11 on the rear side is subtracted. Is stopped, the subtraction of the time display of the time display unit 10 on the leading side is started, and the count display 13 on the lower side of the time display unit 10 blinks.

As described above, the competitor switches the time display automatically only by pointing to the piece. Unlike the conventional technique, the competitor does not need to press the start buttons 14 and 15 each time after starting, and thus forgets to press it. You can concentrate on the competition without doing it.

Since the vibration when a piece is pointed on the shogi board 4 is mainly a vertical vibration, the piezoelectric sensor 3 is mounted on the bottom of the shogi board 4 as in the above embodiment. Thus, the vibration in the vertical direction can be detected well by the piezoelectric sensor 3, whereas the vibration when the side of the shogi board 4 is hit is hard to be detected. Therefore, also in this respect, the illegal vibration can be removed.

In the above-described embodiment, the competition clock of the present invention is applied to shogi. However, the present invention is not limited to this, and it is needless to say that the competition clock can be used for a game such as go and chess, which alternately points to a stone, etc. is there. Further, in the above-described embodiment, the piezoelectric sensor 3 is used as the “detection unit”. However, the invention is not limited thereto, and a sensor or the like for detecting sound may be used.

[0030]

As described above, according to the first aspect of the present invention, the subtraction of the time display section of each competitor is automatically switched only by each competitor pointing at a piece or the like. As in the related art, the player does not need to press the switch, and can concentrate on the competition without forgetting to press the switch.

According to the invention described in claim 2, according to claim 1
In addition to the effect of the above, when the competitor points at the piece or the like, vibration occurs in the game board. Therefore, if this vibration is used, it is possible to easily detect that the competitor points at the piece or the like.

According to the invention described in claim 3, according to claim 1
In addition to the effect described above, when a competitor points to a piece or the like, a sound is generated between the competitor and the game board. Therefore, by using this sound, it is possible to easily detect that the competitor points to the piece or the like.

According to the fourth aspect of the present invention, the first aspect is provided.
In addition to the effects of 3 to 3, during the competition, illegal vibrations such as when releasing the hand pointing at a piece or a stone or when re-hitting occur,
The detection unit may send multiple detection signals,
Even when a plurality of detection signals are transmitted within a predetermined period of time, the control unit determines that these are one signal, and thus has a practically useful effect of preventing occurrence of a malfunction.
