Description

[Detailed description of the invention]

The present invention relates to an electronic watch with a game having a liquid crystal display device. Conventionally, it has been almost impossible to add games to electronic watches due to the limited number of display pixels of the display device of electronic watches, or it has been limited to extremely simple games. SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic timepiece that also serves as a display device and enables a game of competing reasoning abilities with the addition of a relatively simple electronic circuit. The present invention provides an electronic timepiece having a liquid crystal display device including 7-segment numeric display digits, in which the unit position is not displayed in the game state with the upper or lower part of each 7-segment display digit for normal time display. One object whose position is determined by a circuit (hereinafter referred to as M) and the other object which is displayed and whose position is determined by a switch operation (hereinafter referred to as C) are arranged, and when the positions of both objects match, the game is completed. This is an electronic clock with a game that has a logic circuit. The position of C is determined by having a circuit that moves the display by operating one switch (hereinafter referred to as switch A) and determines the position by operating the other switch (hereinafter referred to as switch B). Furthermore, depending on the timing of switch A operation, the reference frequency signal (16Hz in the example)
A circuit is provided that latches the high and low signals of 8 Hz and 8 Hz as random signals and uses them as data signals in the direction of position movement of M. Furthermore, in the present invention, in order to provide the operator with information on the positional movement of M, it is also possible to provide display pixels for displaying the positional movement data of M. Furthermore, the position of M at the start of the game is determined by the reference frequency signal (in the example, 64
It is also possible to have a circuit that stores a reference frequency signal (32 Hz in the embodiment) having a frequency smaller than 32 Hz (32 Hz in the embodiment) every time the switch A is operated and uses it as data. FIG. 1 shows an overview of an electronic timepiece with a game according to the present invention. In the figure, the game is being executed, and the liquid crystal display shows the position of C in the form of a "□" 15, and the position of C is not a hit, that is, the position matches with M, but M is moving, and the movement display 14 shows the position of C. And the vertical movement is displayed. The switch 11 is for switching between a game state and a time display state. Switch A12 moves the moving position of C in a sequential manner, and switch B13 determines the position of C, which is the operation equivalent to dropping the bomb. Of course, switches A and B
may have other meanings in the time display state. FIG. 2 shows display pixels of the liquid crystal display device of the present invention. Six digits are arranged to enable display of hours, minutes, and seconds. D0, D1,..., D1
0 and D11 are identification numbers of M and C's movement locations. Pixel 21 represents the movement of M to the left; pixel 2
2 represents the vertical movement of M, and pixel 23 represents the movement of M to the right. FIG. 3 shows only the display section in two states, a and b, as the game progresses. a is C3
1 is at position D9 and does not match M, M moves to the right without moving up or down, and display 32 represents movement to the right. In b, C and M match and the display of C33 is blinking for a certain period of time. This means that the game has been completed once. Oscillation, frequency division, timekeeping, and
Since the circuit configuration of the drive etc. is a well-known technical content, the explanation will be omitted. FIG. 4 is a circuit diagram for executing game logic related to the basic content of the present invention. Further, a decoder for game display and a multiplexer for display switching are well-known technical contents, and their explanation will be omitted. The table shows the relationship between data signals Cα, Cβ, Cγ, Cδ that determine the position of C, data signals Mα, Mβ, Mγ, Mδ that determine the position of M, and position numbers. Since M and C are also the same code, α, β, γ, and δ refer to the data of both. The decoder can be formed according to the table.

[Table] At the start of a game, the hexadecimal uptown counter 41 and flip-flop 42 are set to the output data of the shift register 46 in the final state of the previous game. These output data Mα, M
β, Mγ, Mδ determine the position of M, but no display is performed. Switch terminal 43 is at low potential (earth), i.e. 0, when switch A is not pressed.
If it is pressed, it is at a high potential (VDD), that is, 1. When switch A is pressed, the signal SAP becomes pulsed and the hexadecimal up counter 45 is operated. The rising timing of the signal SAP is regulated by the rising edge of the reference frequency signal 64Hz. Output data Cα, Cβ, Cγ, C of the counter 45
δ determines the position of C. Based on this value, C is displayed on the display device.
is displayed. However, if switch B is not pressed, C
The value of is not determined. Press switch A until C is at the position desired by the operator. The signal SAP simultaneously becomes a clock signal for the shift register 46, and the shift register takes in the 0 or 1 state of the reference frequency signal 32Hz every time the signal SAP rises, and outputs the data signals Pα, Pβ, Pγ, and Pδ. These signals are sent to the counter 41, flip-flop 42
This is used as a preset input to determine the initial position of M at the start of the next game. The signals Pγ and Pδ are appropriately decoded and input to the counter 41 as signals P'γ and P'δ. The position of M is moved by the counter 41 and flip-flop 42 counting the operation signal SBP of switch B from the value at the start of the game. When the signal IDS is 0, the signal SBP passes through the gate 56 and becomes a clock signal for the counter 41 and flip-flop 42. The up-down signal UDS of the counter 41 is the output of the clock clutch 50, and the 16Hz signal SAP
It latches, and high and low are determined at that timing. The gates 51, 52, 53, and 54 are provided to prevent the gates from going up in the case of the M positions D0 and D1. Therefore, counter 41
The up/down of M is determined each time by the operation timing of switch A, but the clock is too fast for the user to control, and whether M moves to the right or left depends on chance. flipflop 4
The clock enable signal CKS of 2 is an 8Hz signal.
When it is latched at SAP and the signal CKS is 0, Mα does not change. Therefore, whether or not M moves in the vertical direction also depends on chance. The output UDS of the clock clutch 50 represents the left and right movement of M, and is supplied as a display drive signal to FIG. Supplied as a display drive signal. A matching circuit 47 compares the M and C data signals,
The signal IDS becomes 1 only when they are the same. On the other hand, when switch B is pressed, the signal SBP becomes high in a pulsed manner, and when the gate 55 is opened and the signal IDS is 1, the reset latch 48 is set, and a hit condition occurs. In this state, the output Q3 of the counter 49 is 1.
It will be maintained until . When the output Q3 becomes 1, the game ends and the latch 48 is reset and the signal
Put PSP into pulse state. Signal PSP becomes a preset signal for counter 41 and flip-flop 42, and the value of counter 46 according to the timing of the previous final operation of switch A is preset as the starting position of position M in the next game. The signal indicating the hit status is the latch 48 output signal IDS
, left movement is the signal UDS, right movement is the inverse of the signal UDS, and up and down movement is the signal UDS.
It is CKS. In this way, the game is executed, but since M can only move in one direction when it reaches the right or left end, the position information becomes constant.
Also, the position where C has been determined once can be set as the M position if movement is taken into consideration, so the aim can be narrowed down. In other words, this game is an interesting one that combines reasoning and chance. As described above, since the present invention also serves as a display device for an electronic timepiece, it is possible to realize an electronic timepiece equipped with a game that competes for reasoning ability by simply adding a simple circuit and a few display elements.
