The reversal information 35 from 7 and the second mark display information 37 from the second turn mark display circuit 31 are displayed.

The game will start from this state, but
First, prior to playing a game, the button ₅ is operated for a certain period of time to activate the timer 29 using the switch S5, thereby returning the first and second display sections 2a, 2b to zero, and preparing for the game.

Next, the two players decide on the first and second players, and the second player first operates button 6 to turn on switch S ₆ .
When the state is set, a signal is input to the set terminal S of the first RS-FF 21, and the first AND gate 23 is designated by the output signal from the output terminal Q, and at the same time, the first move mark is set by this output signal. The display circuit 30 operates, the first move mark 2c starts blinking based on the first mark display information 36, and the first display section 2
a is ready for operation. As a result, the game officially starts. From this state, if button 5 is operated for a short time, T-FF 28 is inverted, first AND gate 23 is opened, and by passing the time signal φ, the first time counter is activated. 25 starts time counting, and displays the measured time on the first display section 2a according to the first time information 34 to notify the usage time of the previous number.

Next, operate button 4 at the same time as the first person starts,
When the switch _S4 is turned on, a signal is input to the reset terminal R of the first RS-FF21 and no output signal is output from the output terminal Q, the first AND gate 23 is closed and the first time counter 25 stops measuring time. 1st
The display section 2a displays the usage time until the button 4 is pressed, and the first move mark 2c also stops blinking. At the same time, a signal is input to the set terminal S of the second RS-FF 22, so an output signal is output from the output terminal Q, and the second AND gate 24 is opened. By passing the clock signal φ, the second time counter 26 starts measuring time. At the same time, the time measurement is inverted and displayed on the second display section 2b by the inversion information 35 via the display inversion circuit 27, and at the same time, the second hand is The number mark display circuit 31 operates, and the second move mark 2d starts blinking based on the second mark display information 37, and the second display section 2
b starts its operation and notifies the usage time of the subsequent number.
Furthermore, when the second person operates button 6 again at the same time as starting, the output signal is started from the 1st RS-FF21, and the 1st
A signal is input to the hand mark display circuit 30, the first mark display information 36 is started, and the first AND gate 23 is opened to allow the timing signal φ to pass, so that the first time counter 25 starts timing again. At the same time, the first move mark 2c starts blinking on the first display section 2a according to the first time information 34.
The usage time of the previous number is displayed every moment by adding up to the previous usage time.

On the other hand, since the second RS-FF 22 stops the output signal, the input signal to the second move mark display circuit 31 stops and the second mark display information 37 stops, and the second AND gate 24 closes and the clock signal φ stops, the second time counter 26 stops measuring time, the second display section 2b stops blinking the second move mark 2d, and the time used when the button 6 was pressed is displayed in an inverted state. Ru.

Thereafter, in the same way, the first and second players alternately operate their own buttons at the same time as they start.
On the display section 2a, the first move mark 2c flashes to indicate the usage time of the first number, and on the second display section 2b, the second move mark 2d flashes to indicate the reversed usage time of the next number. Displayed while being accumulated.

Next, for example, during break time, it is necessary to stop the timing of both players, but in this case, press button 5.
When the T-FF 28 is reversed by operating for a short time, the first and second AND gates 23, 2
4 is closed, the passage of the time signal φ is stopped, and the time measurement of the first and second time counters 25 and 26 is stopped. As a result, the integration is stopped while the usage time up to that point is displayed on the first and second display sections 2a and 2b, but the first or second RS-FF2
Since the output is being emitted from 1 and 22, the move number mark is blinking in the current state.For example, if the next batting number is the first number, the first move number mark 2c is blinking and only the integration is performed. The player stops the ball and displays the player's turn to bat.

Next, when the break time is over and you want to continue the game, press button 5 again for a short time and press T-FF28.
By further inverting , the first and second AND gates 23 and 24 are opened. As a result, the state before the break time, for example, the first
If the turn mark 2c is blinking, the first AND gate 23 is open and the second AND gate 24 is closed, so the game returns to this state and the first time counter 25 starts counting time and the game begins again. .

When the competition is finally over, the first and second AND gates 2 can be opened by operating button 5 for a short time and inverting T-FF 28 in the same way as during the break time.
3 and 24 are closed, and timekeeping is stopped.

By using it as described above, the game function can be displayed.If you want to use it as a normal clock after the game is over, press the function selection button 3 and the display switching circuit will change the game clock information to the time information. and returns to the clock function mode shown in FIG.

Next, other embodiments of the present invention will be described.

FIG. 4A is a plan view of a digital watch showing another embodiment of the present invention, in which the same members as in FIG. 2 are given the same numbers and their explanations will be omitted.

Figure 4 A clearly indicates the first and second moves by arranging the first and second move marks shown in Figure 2 to imitate the white and black stones used in Go games, for example. At the same time, as shown in FIG. 2, by blinking the turn mark corresponding to the batting number, the batting number is also displayed on the display device. That is, in Fig. 4A, 7 and 8 are the first and second move marks, which are white stone marks 7a and 7a, respectively.
8a and black stone marks 7b and 8b,
It displays the batting number as well as the first and second numbers, and when only the white stone marks 7a and 8a rings are displayed, it indicates that the display side is the first number, and the black stone marks 7b and 8b are also displayed. When it is displayed, it indicates that the display side is the next number. Then, the batting number is indicated by blinking one of the play number marks in the same manner as in FIG.

FIG. 4B is a plan view showing the state in which the digital clock shown in FIG. 4A is switched to the game mode.

In FIG. 4B, a white stone mark 7a is displayed on the first turn mark 7, and this white stone mark 7
Since "a" is blinking, it indicates that the first display section 2a side is the first player and the current batting number. Furthermore, since the black stone mark 8b is displayed on the second turn mark 8, it indicates that the second turn is on the second display section 2b side.

FIG. 5 is a circuit block diagram showing the configuration of the digital timepiece shown in FIG. 4. The basic configuration is the same as that in FIG. 3, and the same members are given the same numbers and their explanation will be omitted.

In FIG. 5, 40 is a write circuit, and 50 is a memory circuit. The structure of FIG. 5 is obtained by adding the write circuit 40 and the memory circuit 50 to the structure of FIG. 3. The write circuit 40 is connected to a third RS-3 for controlling the write by a signal from the timer 29.
It is composed of an FF 41, third and fourth AND gates 42 and 43, and an OR gate 44, which pass signals from external operation switches _S4 and _S6 according to specifications from the third RS-FF41. Further, the memory circuit 50 receives the signal passed through the third or fourth AND gates 42, 43 and stores the writing in the move number mark 7 or 8 of the first or second number.
1,52.

Next, the operation of the digital watch having the above configuration will be explained.

First, when the button 5 is operated, a signal from the timer 29 that outputs a reset signal for returning the first and second display sections to zero is sent to the RS-FF5 of the memory circuit 50.
At the same time, the 3rd RS
-FF41 is set to the set state and a logic "1" signal is generated at its output terminal Q. The third and fourth AND gates 42 and 43 are
becomes the specified state. Here, when the second player operates button 6, the first RS-FF 21 is set, so that signal activates the first move mark display circuit 30, and the first move mark 7 starts blinking based on the first mark display information 36. This indicates that the first display section 2a side is in an integration preparation state. At the same time, the signal from switch _S6 passes through the fourth AND gate 43 in the specified state,
By setting 5RS-FF 52, the memory circuit 50 stores the display modes of the first and second numbers.

Then, the signal from the output terminal Q of the 5th RS-FF 52 activates the first move mark display circuit 30, and the white stone mark 7a is displayed on the first move mark 7 based on the first mark display information 36, and the first move mark 7a is displayed on the first display section. Make it clear that the 2a side has the first turn. And the second move mark 8 for which no signal was input is black stone mark 8b
It will be displayed and you will know that it is the next number.

Further, the operation signal of the switch _S6 which has passed through the fourth AND gate 43 passes through the OR gate 44 and is
By returning the 3RS-FF 41 to the reset state, the third and fourth AND gates 42 and 43 are closed. Therefore, once the signal from switch S ₆ has passed, the write circuit 40 will not operate regardless of whether the signal from switch S ₄ or S ₆ is input, and unless the signal from timer 29 comes again, the write circuit 40 will not operate.・The turn mark for the next turn does not change.

Therefore, from this state, button 5 is pressed as in Fig. 3.
When the first and second players operate buttons 4 and 6 alternately, their usage time will be accumulated and displayed on the display, and at the same time, the white stone mark 7a will indicate the first player. A turn mark will be displayed to indicate which turn it is, and which player's turn it is to bat by blinking.

Thereafter, the game proceeds by performing the same operations as in FIG. 3.

In addition, as for the black stone mark display, only the black stone mark was displayed in the embodiment, but by displaying the white stone mark and the black stone mark at the same time to form a black stone mark, it is possible to unify the size to the same size as the white stone mark. , it is also possible to make the black stone mark more visible.

As described above, according to the present invention, a simple game clock circuit is added to an electronic clock having two display sections capable of displaying the general time and a calendar, and the display is switched between them, and time counter information is displayed on one display section. The display is reversed using a display reversing circuit so that players can easily see their own playing time and know the game time, so it is easy to use with a normal two-level display clock. By adding a circuit, we can provide a game clock, and by displaying necessary information such as batting number, first number, and second number on the play mark, we can provide a game clock that is easier to see and inexpensive. This allows even the average enthusiast to own a game watch, which has the effect of expanding the product appeal of digital watches.
