Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a game clock that is capable of audibly announcing the time remaining in a game such as Shogi or Go in which the playing time of the opponents is determined in advance.

(b) Prior Art Conventional game clocks are disclosed in Japanese Patent Application Laid-open Nos. 16381-1981 and 16382-1982.

All of these conventional game clocks are designed to provide audio notification of the remaining time every predetermined period of time after the start of the game.

(c) Problems to be Solved by the Invention When the remaining time is notified at regular intervals as in the above-mentioned prior art, when there is a considerable amount of time remaining,
Even if you notify the system at regular intervals, it will have little effect as there is still some psychological leeway, but when the time is running low, there will often be a situation where there is a stalemate, and in such cases there are no warning signs. If you inform them, ``How much time do you have left...'' instead, it has a big psychological impact, and often causes people to panic and not be able to think accurately.

In such a case, even a winnable game may end up being a loss, which is a serious problem for the players.

(d) Means for Solving the Problems The present invention allows players to be informed of the time they have in a reasonable manner and without affecting the game. In particular, the moment when the opponent stops thinking is when his or her turn ends, and at this time, the voice notification does not have much of an effect.

Therefore, in the present invention, when one player's turn ends, that is, when a switch is operated to stop the counter that counts the remaining time and activate the counter that counts the other player's time. A voice announcement is made. However, at the beginning of the game, because both players move quickly, the intervals between switch operations are short and they do not need much time information, so having a voice notification every time a switch is operated would make it noisier.
It is possible that it will interfere with the game.

Therefore, in the present invention, at the beginning of the game, voice notification is performed at regular intervals, and towards the end of the game, when both players are gradually stuck and the time consumed per play is getting longer, the sound notification is performed every time the switch is operated. This system is designed to provide audio notifications.

The structure of the audio game clock of the present invention includes a reference signal generator, a bistable switch, and two sets in which counting and stopping of clock pulses from the reference signal generator are performed in opposition to each other by operation of the bistable switch. a subtraction counter; an audio signal generation circuit that generates an audio signal based on the count value of the subtraction counter; and a sound generation circuit that generates audio based on the audio signal from the audio signal generation circuit;
a fixed time detection circuit that outputs a detection signal every time the count value of the subtraction counter is subtracted by a fixed value; an operation detection circuit that detects that the bistable switch is operated; and a fixed time detection circuit that detects that the bistable switch is operated; A remaining time detection circuit detects that the remaining time has fallen below a certain value, and in response to a signal from the operation interval detection circuit, the detection signal from the fixed time detection circuit is activated until the subtraction value of the subtraction counter becomes below a certain value. a selection gate circuit that applies an operation signal to the audio signal generation circuit, and applies a detection signal from the operation detection circuit as an operation signal when the subtraction value of the subtraction counter becomes less than a certain value; It is characterized by:

Next, the operation of the circuit shown in FIGS. 2 to 5 will be explained using the time charts shown in FIGS. 6 to 12.

As mentioned above, the audio notification of the game clock in this embodiment is performed at regular intervals until the remaining time reaches a predetermined time, and when the remaining time becomes less than the predetermined time, the audio notification is performed in accordance with the operation of the bistable switch 6. It will be done. Therefore, the fixed time detection circuit 50 (Fig. 3)
The operation of the switching circuit 52 (FIG. 4) from the start of the game until each opponent's remaining time reaches a predetermined time, and the operation after the remaining time becomes less than the predetermined time will be described first.

As mentioned above, the subtraction counters 20 and 22 operate corresponding to the first move and the second move, respectively, and now, as shown in FIG. 6, the bistable switch 6 is turned on in the direction shown in FIG. 1, and the signal is output. When _C1 is at H level and the subtraction counter 20 is operating, the decode 134 in the fixed time detection circuit 50 inputs the signal _A1 from the subtraction counter 20 and outputs a pulse to each output every 10 minutes. . The pulse output by this decoder 134 is the output signal of the OR gate 138.
Occurs on E ₁ .

On the other hand, the predetermined time detection circuit 16 in the switching circuit 52
0 also inputs the signal _A1 , but keeps its output signal _J1 at the L level until the remaining time for the first move reaches 2 hours. Furthermore, since the FF 164 is reset by the signal I from the inverter 11 in the initial state, its output signals J ₃ and J ₅ are normally at L and H levels, respectively, and the AND gate 176 is opened at the beginning of the game. It is becoming a state.
Similarly, the output signals J ₄ and J ₆ of FF166 are also L,
It is at H level, and the AND gate 178 is initially in an open state.

Therefore, the pulse generated in the signal E ₁ is generated in the output signal J 8 of the AND gate 176 in the switching circuit 52 and is further passed through the OR gate 180 to the signal J ₈ .
Occurs on J ₁₁ and starts voice notification operation. Also,
Since the signal _J6 is at H level, the fixed time detection circuit 5
The AND gate 146 in FF 0 is in an open state, and the pulse generated in the signal E ₁ passes through this AND gate 146 and the OR gate 154 to the FF 15.
is applied to the set input S of 8 to set it. Therefore, the signal _E3 becomes H level, and the player is in a state where the time remaining for the first move is notified.

After that, as shown in FIG. 6, when the bistable switch 6 is switched and the signal _C2 becomes H level,
The subtracting counter 22 is activated and in turn the decoder 136 in the fixed time detection circuit 50 outputs a pulse on each output every ten minutes, which pulse is generated via the OR gate 140 on the signal E ₂ .

The pulse generated in this signal _E2 is transmitted to the switching circuit 5.
A signal _J11 is generated through an AND gate 178 and an OR gate 180 in J2 to start the audio notification operation. Further, as mentioned above, since the signal J ₆ is at H level, the AND gate 1 in the fixed time detection circuit 50
48 is in an open state, and the pulse generated in signal _E2 is applied to the reset input R of FF 158 via AND gate 148 and OR gate 156 to reset it.

This signal _E3 goes to the L level, and becomes in a state of notifying the remaining time of the draw.

Next, as shown in FIG. 7, when the remaining time for the first move reaches two hours, the predetermined time detection circuit 160 detects this and outputs a pulse to its output signal _J1 . The pulse generated in this signal _J1 is FF164
is applied to the set input S of , to set it.
As a result, the output signals J ₃ and J ₅ of the FF 164 become H and L levels, respectively, and the AND gate 176
Instead, the AND gate 172 becomes open.

After this, even if a pulse occurs in the signal _E1 , this pulse is connected to the AND gate 176 and the OR gate 1.
The signal J ₁₁ is not generated through 80, and the time remaining for the first move is not announced at regular intervals.

After that, bistable switch 6 switches the signal
When _C2 becomes H level, a pulse is output from the one-shot multivibrator 168 in synchronization with this rise, and this pulse is applied to the AND gate 172 and OR gate 180, which are already open.
A signal J11 is generated via the signal _J11 to start the voice notification operation. Furthermore, when the signal C ₂ becomes H level, a pulse is also output from the one-shot multivibrator 142 in the fixed time detection circuit 50, and since the signal J ₅ becomes L level, the AND gate 150 is in an open state. and via or gate 154
Applied to set input S of FF158.

Therefore, the signal _E3 becomes H level, and the player is in a state where the time remaining for the first move is notified.

At this time, if the remaining time of the drawer has not yet reached 2 hours, the FF 158 is reset again by the pulse generated in the next signal E ₂ , and a pulse is also generated in the signal J ₁₁ . , the time remaining on the draw is announced at regular intervals.

Then, when there are two hours left in the remaining time, a pulse is generated in the output signal _J2 of the predetermined time detection circuit 162 in the switching circuit 52, and the FF 166 is set by this pulse, similar to the operation described above. As a result, AND gate 174 instead of AND gate 178 becomes open. Even if a pulse is generated in the signal _E2 in this state, this pulse is not generated in the signal _J11 , and the notification operation does not start.

Thereafter, when the bistable switch 6 is switched and the signal _C1 becomes H level again, a pulse is output from the one-shot multivibrator 170 in the switching circuit 52, and this pulse is passed through the AND gate 174.
and is generated at signal J ₁₁ via OR gate 180,
Start the voice notification operation. Also, signal _C1 is H
When the level is reached, a pulse is also output from the one-shot multivibrator 144 in the fixed time detection circuit 50, and the signal J ₆ is at the L level, so the pulse is outputted to the FF 158 via the AND gate 152 and the OR gate 156, which are open. is printed on the reset input R of the

When the FF 158 is reset, the signal _E3 goes to L level, and the player is in a state where he/she is notified of the remaining time of the draw.

In this way, the output signal of the switching circuit 52 (FIG. 4) remains unchanged until the remaining two hours of the opponent's time remain.
A pulse is generated in _J11 at regular intervals to start the notification operation, and when the remaining time of the opponent becomes less than 2 hours, a pulse is generated in signal _JJ1 every time the bistable switch 6 is operated. This will start the notification operation.

Next, the operation of the circuit shown in FIGS. 2 and 5 will be explained.

As described above, from the start of the game until the opponent has two hours, a pulse is generated in the output signal _J11 of the switching circuit 52 at regular intervals.

Now, a pulse is generated in the output signal _E1 of the fixed time detection circuit 50, and in response to this, as described above, a signal is generated.
When _E3 becomes H level, the multiplexer 104 in the time audio code output circuit 56 becomes in a state to output the signal _A1 from the subtraction counter 20, and the multiplexer 102 outputs the signal A1 from the subtraction counter 20.
The code ROM 92 is now ready to output signals, and these output signals are applied to the multiplexer 106 along with the output signals of the other code ROMs 96-100.

As will be described later, the outputs _Q0 to _Q5 of the counter 108
When successively becomes H level, this multiplexer 1
All the signals sequentially output from the multiplexer 106 are applied to the multiplexer 58, and since the normal signal L is at the L level, the multiplexer 58 transfers the signal from the multiplexer 106 to the audio signal generating circuit 64.
to be applied.

On the other hand, when a pulse is generated in the signal _J13 , the counter 108 in the time audio code output circuit 56 is reset and its output _Q0 becomes H level, and a pulse is also generated in the signal ₁ via the OR gate 126. FF 130 is set by the pulse generated in this signal _M1 .

When FF130 is set, its output signal M ₂
becomes H level, which causes AND gate 1
32 becomes open, and the clock signal _φ1 is generated as its output signal _M3 .

The address counter 186 in the audio signal generation circuit 64 (FIG. 5) is activated when this signal _M3 is input, and has already been input to the multiplexers 102, 106, 58.
A signal from the "Sente" code ROM 92 is applied to the start address designation ROM 182 via the start address designation ROM 182, and the address counter 186 reads data from the audio ROM 62 from the start address a of the audio "Sente" corresponding to this signal. Converter 194, low pass filter 196 and sound generation circuit 6
The voice "sente" is emitted through the address counter 8, and the output signal of the address counter 186 at this time is also applied to the digital comparator 188.

On the other hand, the signal from the multiplexer 58 is also applied to the end address designation circuit 184, and this end address designation circuit 184 applies the end address a+b of the voice "Sente" corresponding to the input signal to the digital comparator 188.

In this way, when the end address a+b from the end address designation ROM 184 of the final address of the voice "Sente" designated by the address counter 186 is applied to the digital comparator 188, the digital comparator 188 detects that the input signals match. Generate one pulse in the output signal.

This pulse is generated at the output signal H of the AND gate 192, which is normally open, and is applied to the clock input φ of the counter 108 via the OR gate 122 (FIG. 2) to advance the count of the counter 108 and its output. Set output _Q1 to H level.

When the output _Q1 of this counter 108 becomes H level, the multiplexer 106 outputs the signal from the "AT" code ROM 96, and similarly to the operation described above, the start address designation ROM 182 in the audio signal generation circuit 64 and the end address designation
The ROM 184 sequentially outputs the start address c and end address c+d of the voice "ato". Therefore, the address counter 186 reads data from the audio ROM 62 according to the start address, and outputs the audio "ato" from the sound generation circuit 68.
is issued, and at this time digital comparator 1
The final address and end address c+d of the voice "ato" designated by the address counter 186 are applied to 88, and this digital comparator 188 detects that the input signals match and generates a pulse again in its output signal.

This pulse is generated by the signal H, similar to the operation described above.
occurs, and the counter 108 increments the count.

In this way, the counter 108 advances the count by the pulses sequentially generated in the signal H, and the multiplexer 106 outputs "sente", "ato", "ni", etc.
Each code signal of "Jikan", "Sanjiyutsu", and "Pun" is outputted, and is transmitted through the multiplexer 58, the audio signal generation circuit 64, and the sound generation circuit 68 as shown in FIG. is emitted.

When this sound is emitted, the final pulse generated in the signal H causes the output _Q6 of the counter 108 to go to the H level, which causes a pulse to be output from the one-shot multivibrator 124, which resets the FF 130 via the OR gate 128. The AND gate 132 is closed and the notification operation ends.

Thereafter, when the bistable switch 6 shown in FIG.
A pulse is generated in the output signal _E2 of _the fixed time detection circuit 50 which inputs the signal _A2 from
A pulse is generated in the output signal J ₁₁ of .

In this way, when the signal _E3 becomes L level, the multiplexer 10 in the time audio code output circuit 56
4 and 102 are switched to output the signal A ₂ and the signal from the "trowel" code ROM 94, respectively.

Therefore, as described above, the pulse generated in the signal _J11 causes the output signal of the voice start circuit 66 to
When the clock signal _φ1 is generated at _M3 , a pulse is generated in the output signal H of the audio signal generation circuit 64, the counter 108 is activated, and the multiplexer 106 sequentially outputs "gote", "ato", "san", " Jikan”, “
The code signals "nijiuyu" and "pun" are output, and the sound "gote" is outputted via the multiplexer 58, the sound generation circuit 64, and the sound generation circuit 68 as shown in FIG.
Ato San Jikan Nijiuyu Pun” is uttered.

Thereafter, when the remaining time for the first move is less than two hours, a pulse will be generated in the output signal _J11 of the switching circuit 52 when the bistable switch 6 is operated as described above.

As shown in FIG. 9, when the bistable switch 6 is switched and the signal C ₂ is set to H level, the signal J ₁₁ is activated periodically at the rising edge of the signal C ₂ as described above.
A pulse is generated.

At this time, the bistable switch 6 is switched to the direction of measuring the holding time of the second hand, but as described above, the output signal E ₃ of the fixed time detection circuit 50 is high.
level, so multiplexer 104, 102
are respectively signal _A1 and "Sente" code ROM92
It is now ready to output signals from.

Therefore, the voice "Sente ato ichi jikan sanjiyutsu pun" is emitted by the same operation as the time limit notification for the first move described above.

Also, if the time on the draw is less than 2 hours,
Similar to the operation described above, when the bistable switch 6 is switched and the signal C ₁ becomes H level and the time for the first move is measured, the time for the second move will be recorded as a voice like "Gote ato ichi jikan nijiyutsu pun". Emitted.

Thereafter, when the remaining time of one or both of the first move and the second move becomes less than one hour, the "0" time detection circuits 70 and 74 in the zero time detection circuit 48 output the signals A ₁ and A ₂ from the subtraction counters 20 and 22, respectively. It is detected that the time has changed from 0 to 0, and the output signals B ₁ and B ₃ are set to H level.

Now, when the signal E ₃ is at H level and the signal B ₁ goes to H level while the time for the first move is being measured, the output signal of the AND gate 110 in the time audio code output circuit 56 goes to H level, and the OR gate 116 is activated. Via the signal _N3 occurs. Therefore, the AND gate 118 is in an open state, and as mentioned above, the signal
A pulse is generated at J ₁₁ to start the voice notification operation, and the counter 108 is advanced. When the output Q ₂ or Q ₃ of the counter 108 becomes H level, the output signal N ₂ of the OR gate 114 also goes to H level. , and the output signal _N4 of the AND gate 118 also becomes H.
become the level.

Therefore, the AND gate 120 is also opened, and the clock signal _φ1 is generated as its output signal _N5 .

The clock signal φ ₁ generated on the signal N ₅ is applied to the counter 108 via the OR gate 122.
Fast forward that count. Therefore, when the outputs Q _{2 and} Q ₃ of the counter 108 for outputting the audio code of the hour digit from the multiplexer 106 go to H level, the count of the counter 108 is immediately fast-forwarded, and the audio code of the hour digit, for example, the audio ”,
Before the "time" code is output from the multiplexer 106, the next minute digit audio code is output. As a result, the audio signal generation circuit 64 reads the audio code excluding the audio code of the hour digit from the audio ROM 62, and the sound generation circuit 68 emits the audio "Sente at gojiyu pun" as shown in FIG.

Next, when the signal E ₃ is at the L level and the signal B ₃ goes to the H level while measuring the duration of the second hand, the output signal of the AND gate 112 in the time audio code output circuit 56 goes to the H level, and this causes Then, the output signal _N3 of the OR gate 116 becomes H level. The operation after this is similar to the operation described above, and the sound generation circuit 68 outputs the sound "gote" as shown in FIG.
Ato Sanjiyuthu Pun” is uttered.

After that, when one of the opponents runs out of time, the "0" time detection circuit 70 and the "0" minute detection circuit 72 or the "0" time detection circuit 74 and the "0"
The minute detection circuit 76 detects this and outputs its output signal B ₁ , B ₂ or
B ₃ and B ₄ become H level.

That is, when the time for the first move runs out, the signal B ₁ ,
_B2 goes to H level, and the output signal _B5 of AND gate 78 goes to H level.When the time on the back side runs out, signals _B3 and _B4 go to H level, and the output signal _B6 of AND gate 80 goes to H level. Becomes H level.

Therefore, the output signal of AND gate 78 or 80 corresponding to the opponent whose time runs out first
B ₅ or B ₆ becomes H level and is applied to the multiplexer 90 in the end audio code output circuit 54.

This multiplexer 90 is in a state where it outputs the signal from the "Gotenokachi" code ROM 88 when the signal B ₅ goes to H level, and also when the signal B ₆ goes to H level.
When you reach the level "Senteno Kachi" code ROM8
The state is such that the signal from 6 is output.

Further, when one of the signals B ₅ and B ₆ goes to H level, the output of the OR gate 82 goes to H level, thereby causing the one shot multivibrator 84
A pulse is generated in the output signal _B7 of.

When a pulse is generated in this signal _B7 , the FF 60 is set and its output signal L becomes H level.

When this signal L becomes H level, the multiplexer 58 switches to a state in which it outputs the signal from the multiplexer 90 in the end audio code output circuit 54, and the audio signal generation circuit 64 which inputs this signal
The start address specification ROM 182 and the end address specification ROM 184 inside are the voice "Gotenokachi".
Or memorize the start address and end address of "Senteno Kachi".

On the other hand, the pulse generated in signal B ₇ is also generated in output signal M ₁ of OR gate 126 to set FF 130, thereby generating clock signal φ ₁ in output signal M ₃ of AND gate 132. This signal M ₃ causes the audio signal generation circuit 64 to read the data of the audio ROM 62 from the address specified by the start address designation ROM 182 mentioned above, and output the data to the D-A converter 194 and the low-pass filter 1.
96 and the sound generation circuit 68, the voice "Gotenokachi" or "Sentenokachi" is generated.

At this time, when the address counter 186 specifies the end address of the voice "Gotenokachi" or "Sentenokachi", the digital comparator 188 detects that the output signal of the address counter 186 and the output signal of the end address designation ROM 184 match. Outputs pulses. This pulse is generated in the output signal K of the AND gate 190, which is in an open state because the signal L is at the H level.
The FFs 60 and 130 are reset and the audio notification operation is ended.

As described above, in this embodiment, until a predetermined time, such as two hours remaining, is reached, the player is notified of the remaining time by voice at regular intervals, and when the remaining time reaches the predetermined time, the bistable switch 6 is activated. In response, a voice notification of the time remaining is provided.

(f) Effects of the Invention According to the present invention, a voice notification is made at regular intervals until the time limit reaches a predetermined time, and when the time limit reaches a predetermined time, a voice notification is made in response to a switch operation. Voice notification can be made without affecting the status.
