Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a game in which multi-digit numbers entered on two sets of keyboards are matched against each other, and relates to a small electronic game device in which the degree of matching is judged and displayed by an electronic circuit. It is something.

In this game, the numbers entered by each other must not be known by the other party, and the number of hits must be checked, so a third party is required, but this is done using an electronic circuit to ensure fair judgment. It can be done and the process is fast.

In this game device, each player tries to guess the number of the other player, but each time the player's number changes and the percentage of hits changes, the display points come and go, giving the appearance of netting.

Once you get used to it, you will be able to devise strategies and play more varied games.

A case will be described in which this device is implemented as a three-digit number guessing game.

FIG. 1 shows the appearance of one embodiment of the device of the present invention, and shows the main body 70.
Includes power switch 79, reset switch 20, and LED
A display line 26 in which light emitting diodes (light emitting diodes) are lined up, and operation display lamps 14 and 18 are provided, and a determination circuit is built-in.

The two keyboards 1 and 6 have lead wires 77.7 to the main body 70.
8 and is electrically connected.

FIG. 2 shows a comparison between the display position of the LED and the numbers input from the two sets of keyboards.

In this case, if the numbers in the same place match, you get a score of 2, if there is 1 letter in the other place you get 1 point, and if there are 2 letters in the same place, you get 2 points.

If they match perfectly, the winning side wins; if they score 7 or more points, the winning side wins, and a light-emitting display at the edge of that side lights up, and the game ends.

FIG. 3 shows a block diagram of the circuit of the main body of the device.

The function of the device will be explained based on this.

First, when the power is turned on, the flip-flop (hereinafter F,
Gate 12 or 16 depending on the output of 11 (abbreviated as F)
is opened and this output causes the driver 13
or 17 is activated and the indicator 14 or 18 is turned on and at the same time the gate 15 or 19 is opened and the keyboard 1
Or input from 6 to memory 3, 4, 5 or 8, 9, 1
Prepare to send to 0.

Reference numerals 2 and 7 are encoder shift signal generators, which perform encoding for inputting key input into memory and generate shift signals for feeding.

Now, at the start of the game, it is possible to do this automatically, but in this example, the reset switch 20 resets the central point of the group of light-emitting display points (hereinafter abbreviated as display line) 26 in the linear arrangement. is displayed in a luminescent manner.

After the reset switch 20 outputs a signal from the signal generator 21 and clears the contents of the left/right shiftable shift register group 24, the output from the delay signal generator 22 is input to the central register 24, and this signal causes the driver group 25 to be output. The center point of the display line 26 is displayed by emitting light.

The clock signal is sent through the OR gate 23.

If, for example, the display 18 lights up depending on the state of the FF 11 set when the power is turned on, the first key input must be performed from the keyboard 6.

Input from keyboard 1 is blocked by gate 15.

The 3-digit number entered from the keyboard 6 is sent to the encoder 7
are sequentially stored in the memory 8.9.10.

In this case, the shift signal exiting through AND gate 19 causes the memory contents to be shifted one after the other, while at the same time the shift signal is applied through OR gate 27 to counter and signal generator 28.

The signal generator 28 generates a switching signal when three shift signals are received.

Switch 29 is set to the no time limit side (
(as shown in the figure), the signal from the signal generator 28 causes F
F11 is inverted, but if there is a time limit, the timer 30 adds one more signal after a certain period of time, so if there is no key input from the keyboard 1 within the time, FF11 is inverted again.

If a three-digit number is input from the keyboard 1 within the time, the timer 30 is further extended by a predetermined time from that point, so the keyboard 6 side is now subject to a time limit.

31 is the or gate.

The signal generated by the signal generator 28 has another role, namely:
It is used as a signal to check input numbers and start counting points.

This signal sets R-8FF32 and AND gate 3
Make a signal to open 3.

At the same time, the AND gates 12 and 16 are closed by the output of the FF 32 in order to prohibit input from the keys while counting.

Now, this example shows a method in which the input numbers are compared in parallel, and a group of logic comparators 34 to 42 are provided for this purpose.

Of these, the logic comparators 34, 37, and 40 output when the numbers of the same rank match, and the gates 43, 44
, 45.

Further, if all of these logic comparators 34, 37.degree. 40 have outputs, an output is output from the AND gate 46, operating the timer 47, and opening the gate 48 or 49.

The operation of this timer 47 will be described later.

The gates 48 and 49 are for displaying "win" on the side whose numbers match, and pass a signal through the driver 50 or 51 to display the display point at the end of the display line 26 by emitting light. .

This signal uses the output of the FF 11, but since it is inverted when the three-digit number is input, the output from the opposite side is used.

Gate groups 43 to 45 and 52 to 57 are for outputting scores from the collated results.

The signal of this score is obtained by converting the pulse signal from the oscillator 58 into a time series by a counter 59 and a decoder 60, and extracting the pulse signals in number corresponding to the score using a gate group of 43 to 45 degrees and 52 to 57.

With this method, it is possible to correctly add up scores without overlapping the results of parallel matching.

Depending on the number of pulse signals, the contents of the register 24 are shifted left and right (up and down in the figure) by that number, and the shift mode (left or right) is switched using one side of the output of the FF 11.

Since the register 24 initially has H()/E level) placed in the center by the reset switch, this will be shifted left and right by the above-mentioned shift signal.

Then, the score of either side is a fixed point (7 in this example).
In order to display "win" if the score exceeds (points), the register 24
When the count reaches a certain number, a signal is sent to the AND gate 46 via the OR gate 64 to cause it to perform a "win" operation in the same way as in the case of a complete match of three digits.

The timer 47 is provided for the following operations.

In Figure 2, in the process from the 20th step to the 21st step, even if the key human power A side can be perfectly matched, in reality, only 6 points will be obtained, so the displayed points will not reach the end. It stays in the middle without moving.

In order to avoid this, it is necessary to perform an extra shift and push it out of the display line.

In this example, the oscillator 5 is activated for a certain period of time by the timer 47.
A method is adopted in which the pulse from 8 is directly sent to the gate 23 through the gate 61.

As mentioned above, the "win" display at the end is performed regardless of the above-mentioned shift.

This concludes the explanation of the operation.

In addition to the method shown here, the circuit configuration can also be used for example, number matching,
Of course, it is also possible to consider a method of performing time-series processing (that is, matching one pair at a certain time and matching another pair at the next time) or parallel addition/subtraction processing in score counting.

Most of the circuits in the present invention can be integrated, and a lightweight and compact display can be realized.

A feature of the game device of the present invention is that it is possible to play the game even if the user does not initially know the meaning of the points, and the fun is doubled when the game is played by a group of people who understand the meaning.
