Among them, electronic game devices such as car races and motorcycle races that require operations corresponding to screen changes are gaining popularity. In this electronic game device, for example, in a car race game, the vehicle speed and the traveling direction of the own vehicle are operated with respect to the displayed course and the other vehicle, and the own vehicle is displayed on the displayed course while avoiding collision with the other vehicle. It is designed to run in the appropriate direction as fast as possible.

However, in the racing game device as described above, it is unnatural because the course suddenly changes, for example, the displayed course suddenly changes from a straight course to a right curve or a left curve. It was difficult to deal with and there was the inconvenience that the fun was halved.

[Purpose of device]

This invention was made in view of the above situation,
It is an object of the present invention to provide an electronic game device that allows a player to recognize in advance information about a change in a screen displayed during execution of a game, such as a curve in a car racing game.

[Key points of device]

According to this invention, display screen information according to the progress of the game is stored, information displayed after the currently displayed information is read, and the next screen change is notified.

[Example of device]

Hereinafter, an example in which the present invention is applied to a car racing game will be described with reference to the drawings. FIG. 1 shows an external configuration, and 1 is a case body. This case body 1
A game start key 2, a handle switch 3 for operating the traveling direction, an acceleration / deceleration switch 4 for speed adjustment, and the like are provided on the front surface of the player, as well as a display section 5 formed of, for example, a liquid crystal display element. The display unit 5 displays a curb indicating a running course, a racing car of the own vehicle and other vehicles, and a navigation display indicating the direction of the curve in advance when the next course is a curve. Done.

Next, the structure of the electronic circuit provided in the case body 1 will be described with reference to FIG. In the figure, reference numeral 11 denotes an input unit including the start key 2, the handle switch 3, the acceleration / deceleration switch 4 and the like. The control unit 12 discriminates an operation signal input from the input unit 11 and performs a display control operation according to the discrimination content, and performs data input / output with a course data storage unit 13 that stores course data. At the same time, the data is sent to the display data memory 14, the direction register 15, the distance register 16, the distance register 17, and the course direction designating section 18. The display data memory 14, the direction register 15 and the distance register 16 are composed of one RAM or the like. The display data memory 14 stores the display data necessary for the display unit 5, and also the direction register 15 and the distance register 16 Stores the course direction data and the distance data of the section course data at that time sent from the course data storage unit 13, and the stored contents of the display data memory 14, the direction register 15, and the distance register 16 are It is sent to the display drive circuit 19. Above distance setting unit 17
Is for setting the distance data among the divided course data stored in the course data storage unit 13 by the control unit 12, and the set data is sent to the distance register 16 and the remaining distance counter 20. This remaining distance counter 20
After setting the distance data sent from the distance setting unit 17, the contents are counted down by the distance down count signal from the control unit 12 as the game progresses, and the count value becomes a constant value. The remaining distance determination unit 21 determines whether or not the distance is satisfied. This residual distance determination unit
The judgment result of 21 is sent to the control unit 12. Further, the course direction designating section 18 designates the course direction data of the divided course data stored in the course data storage section 13 by the control section 12, and the designated data is the direction register 15 and the direction judging section. Sent to 22. The direction determining unit 22 determines the direction to be navigated to next by using the direction data input from the course direction designating unit 18 and the direction register 15, and inputs the determination data to the control unit 12. Then, the display drive circuit 19
Drive the display unit 5 according to the display data.

FIG. 3 shows an example of the contents of the course data stored in the course data storage unit 13, which is divided into addresses "001" to "n-1" according to the set course data. The course data such as "straight line" and "right curve" and the corresponding distance data are stored. Then, the course direction data "GOAL" indicating the end of the course data and the distance data "0" are stored in the last address "n".

Fig. 4 shows an example of the actual setting course. In this case,
The course is a clockwise track, which consists of two straight lines and two right curves, and the navigation display of the next section is performed between the section end position in each section and a specific distance.

Next, the operation of the above embodiment will be described in detail with reference to FIG. FIG. 5 is a flow chart for controlling the reading of the course data and the display operation corresponding thereto. First, when the game start key 2 is operated, the section course data stored at the head address of the course data storage unit 13 is read out first. To be done. This section course data is composed of course direction data and distance data as shown in FIG. 3, and the course direction data is sent to the direction register 15 and the direction determination unit 22 by the course direction designating unit 18, and the distance data. Is the distance setting unit 17 and the distance register 16 and the remaining distance counter.
20 are set for each memory. Next, as shown in step S01, the control unit 12 outputs a distance down count signal to the remaining distance counter 20, and the count value of the remaining distance counter 20 is counted down. Then, the count value of the countdown remaining distance counter 20 is judged by the remaining distance judging unit 21. In this case, first, in step S02, it is determined whether or not the count value is "0". If it is not "0", then, as shown in step S03, this time is "200 (m) or less". It is judged whether or not. If it is not "200 or less", it is not necessary to change the display content on the display unit 5, so
After the processing is completed, the processing from step S01 is performed again. If it is "200 or less", it is necessary to display the navigation, so proceed to step S04,
The direction determining unit 22 determines the course direction data designated in the direction register 15. Here, if the course direction data is "straight line", it means that the straight line course is currently being displayed on the display unit 5, so that the following step S05 is performed.
In, it is specified that the next section course is a left or right curve. Therefore, in the next step S06, the control unit 12 displays the section course data at the address next to the section course data currently displayed in the course data storage unit 13 in order to perform the navigation display of the next section course. The course direction data is read out and sent to the course direction designating section 18. The direction determining unit 22 determines the curve direction based on the data from the course direction designating unit 18, and if the curve direction is right, the step S0
Proceeding to 7, the control unit 12 sets the right arrow display data in the display data memory 14, the display drive circuit 19 causes the display unit 5 to navigate and display the right arrow, and the process ends. If it is determined that the curve direction is to the left,
In step S08, the left arrow display data is set in the display data memory 14, the left arrow is navigatingly displayed on the display unit 5, and the process ends. If the course direction data stored in the direction register 15 in the step S04 is “right curve” or “left curve”, it means that the curve course is currently being displayed on the display unit 5, so In step S09, the next section course is designated as a straight course. And the following step S1
At 0, the direction of the curve course currently displayed is judged. If it is a left curve, in order to navigate and display the next straight course, the process proceeds to step S07, the right arrow is displayed, the process ends, and the operation from step S01 is repeated. Also in the case of a right curve, in the same way, for navigating display of the next straight course, the process proceeds to step S08, the left arrow is displayed and the process ends, and the operation from step S01 is repeated again. . When it is determined in step S02 that the count value of the remaining distance counter 20 is "0", this means that the navigation display section currently displayed on the display unit 5 ends and the next running course is not displayed. Therefore, the procedure proceeds to step S11, and the left or right arrow that is being navigated is erased. Then, the course direction data of the new section course data is read from the course data storage unit 13, and the course direction data is stored and set in the direction register 15 and the direction determination unit 22 by the course direction designation unit 18.

Next, as shown in step S12, the direction determination unit 22 determines the course direction data stored and set. In this case, if the course direction data is a straight line, the process proceeds to step 13, the straight line course data is stored in the display data memory 14, and the straight line course is displayed on the display unit 5. After that, step S1
At 4, this time, the distance data is read from the course data storage unit 13, is set in the distance register 16 and the remaining distance counter 20, and the processing is ended. When it is determined in step S12 that the direction designation is the left curve or the right curve, the process proceeds to steps S15 and S16, respectively, and after the left curve or the right curve is displayed on the display unit 5, the above step S14 is performed. The distance data is set and the process ends.

FIG. 6 shows an actual display change on the display unit 5, and FIG. 6 (1) shows a display state in a straight course. In this case, the curbstone 51 for indicating a straight line course, the own vehicle 52, the other vehicle 53, etc. are displayed in a straight line on the display unit 5. At this time, the direction data register 15 is stored in the direction register 15.
The straight course data is stored as the course direction data from 13, and the distance data corresponding to the straight course data is set in the distance register 16 and also in the remaining distance counter 20. The count value of the remaining distance counter 20 is counted down by a distance down count signal input from the control unit 12 at time intervals corresponding to the operation position of the acceleration / deceleration switch 4.

Then, when the count value of the remaining distance counter 20 becomes "200", the remaining distance judging unit 21 judges this as shown in FIG. 6 (2), and determines the direction data of the next section course data. It is read and the right arrow 54 is navigated and displayed on the display unit 5 as shown in step S07.

Even after this, the remaining distance counter 20 continues to count down, and when the count value becomes “0”, the right arrow 54 is erased as shown in FIG. View course. In this case curb
By changing the display position of 51 and other vehicles 51, the course of the right curve is expressed. With this change of the course display, new distance data corresponding to it is displayed in the distance register.
16 and the remaining distance counter 20 are set, and the remaining distance counter 20 performs a countdown operation starting from that value.

Then, when the count value of the remaining distance counter 20 becomes "200", as shown in FIG.
Judges this and displays the left arrow 55 on the display unit 5 for navigation for the "straight line" course which is the next section course.

After that, the remaining distance counter 20 counts down according to the distance down count signal from the control unit 12, and when the count value becomes “0”, it is shown in FIG. 6 (5).
As shown in Figure 5, while turning off the display of the left arrow 55 which is a navigation display, the course direction data "straight line" of the new section course data is read from the course data storage unit 13, and the curbstone 51, the other vehicle 53, etc. are read accordingly. Use to display a straight course.

In this way, since the navigation display is made in a direction in which the course changes from a point that is a certain distance before the point in which the course direction changes, the player can detect the change in the course direction in advance.

In the above embodiment, the display unit 5 is shown to be composed of a liquid crystal display element, but the present invention is not limited to this, and other cathode ray tubes, LEDs, fluorescent display tubes or the like may be used. .

Further, not only car racing but also various things such as motorcycles, boats, and horse racing can be considered.

Then, in this embodiment, as the navigation information, the arrow is displayed according to the direction of the curve, but this may also display the word "right curve", or by voice, "right curve", etc. In addition to the curve, an obstacle, an uphill, a downhill, a bridge, a branch, or the like may be displayed as the navigation information.

Further, as a method for detecting that the traveling distance has reached a specific value, the distance data is down-counted and the remaining distance is determined in the above embodiment, but the present invention is not limited to this, and the distance count is incremented from "0". It may be detected by starting counting and when the difference between the distance data and the count value (remaining distance) reaches a specific value.
