The electrodes 8, 9 are connected to a CPU, etc. and the input signal formed when the electrodes 8, 9 contact is fed to the CPU, etc.

Description

[Detailed description of the invention] Technical field The present invention relates to an electric f'a device having a distance calculation function.

PRIOR ART Conventionally, this type of electronic equipment has a rotating part as a distance calculation function, and the rotating part uses the rotating part to create a map. Move the
The amount of rotation was calculated and the amount of movement was output, and the distance was calculated by multiplying that value by the scale of the map.

However, with such devices, if the rotating part is small, reliable rotation cannot be obtained, and if the rotating part is large, even if reliable rotation can be obtained, the details of the road on the map cannot be accurately traced, resulting in errors. The disadvantage was that it became larger. It was inconvenient that the correct distance could not be determined unless the output numerical value was multiplied by the reciprocal of the scale factor.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to have a distance calculation function that easily and accurately outputs the actual distance of a predetermined portion of the map 1-. Our purpose is to propose electronic devices.

EXAMPLE Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to screens.

FIG. 1 shows the overall appearance of an electronic device according to an embodiment of the present invention, where l is the main body of the electronic device, and 2 is the entire electronic device l.
A transparent keyboard panel section 2 is provided on the top of the map and is used to input distances on the map. Electronic device body
A display 3 for displaying input numerical values, converted distances, symbols, etc., and a keyboard section 4 for displaying various keys are arranged at the bottom of the screen. The display 3 is, for example, a liquid crystal display composed of a driver I, a driver I, and a driver I.

The input keys are [absolute for numbers 0 to 9J], 10 numeric keys 5 for entering numbers, a clear key 7 for erasing the contents, and specifying the start of input on the transparent keyboard panel section 2. A "start" key 6 is arranged.

FIG. 2 is a sectional view of the transparent keyboard panel section 2 of this embodiment. Reference numeral 10 denotes a film-like transparent sheet that forms two sides of the transparent keyboard panel portion 2, and 11 represents a transparent substrate made of a film-like sheet or a thin glass plate, which forms the lower surface. A large number of straight transparent electrodes 8, 9 are printed on the lower surface of the transparent sheet 10 and on the opposite surface of the transparent substrate 11 with minute intervals (several millimeters) between them. Transparent sheet 10
and transparent substrate 11 are placed so that their transparent electrodes 8 and 9 are orthogonal to each other and face each other with a minute gap in between, as shown in FIG. With the following configuration, the transparent sheet lO
When pressure is applied to the surface of the transparent electrode 8, only the area where the pressure is applied moves downward, and the transparent electrode 8 comes into contact with the electrode Fj9. Further, the transparent electrodes 8 and 9 are connected to the CPU etc. by electric wires 12.degree. 13, and a human input signal based on the contact of the electrodes 8.9 is sent to the CPU etc.

FIG. 4 shows the overall configuration of the control circuit of this embodiment. The aforementioned keyboard section 4 and transparent keyboard panel section 2
is a code converter 1 that converts the key λ signal into a binary code.
The display unit 3 is connected to the CPU 15 through the CPU 15.
The entire display is connected to the CPU 15 via an output control section 16, which is a decoder drive circuit that converts the output signal of the display 3 into a drive signal for the display 3. The CPU 15 is a central processing unit, and performs various signal processing based on human input signals sent to the transparent keyboard panel section 2 and the keyboard section 4 via the code converter 4, and performs overall control in addition to calculations and output of calculation results. 91. CPU
3-5 has a built-in ROM that stores a control program, a random access memory RAM used for data processing, and the like. Inside the random access memory RAM, there are four memory sections RAM0 to RAM3 for inputting and outputting data related to calculations for determining the movement .psi.

Next, the operation of this embodiment having the following configuration will be explained using FIGS. 4 and 4. Hereinafter, the explanation will be given by taking as an example the case of calculating the actual distance from point A (school) to point B (shrine) on map 17-L shown in FIG. 5.

First, when the scale of the map 17 is 1/500, when the number keys 5 are pressed in the order of r5-0-5J, a signal is emitted from the keyboard section 4, and the code of r500J is converted via the code converter 14. A data signal is input to CPU15. The CPU 15 sends the input data signal to the output control section 16. The output control unit 16 converts the data signal into a drive signal and sends it to the display 3.
is displayed as r500J.

Next, the electronic device body 1 is placed on the map 17J- so that the transparent keyboard panel 2 includes the area from point A to point B, and the start key 6 of the keyboard section 4 is pressed. Then, while pressing the transparent keyboard panel section 2, trace along the path from point A to point B on the map 17 that can be seen through the transparent keyboard panel section 2 (the part indicated by the broken line in the figure). As a result, the transparent electrodes 8 and 9 in the transparent keyboard panel section 2 contact each other sequentially as the traced portion moves, thereby emitting a signal, and the signal is converted into a code via the code converter 14 and sent to the CPU 15 as movement amount data. is input. The CPU 15 receives the input movement amount data signal, adds the number of traced electrodes, and sequentially multiplies the result by the already input reduction scale r500J to calculate the movement distance. Next, the display r500J on the display 3 is erased, and one piece of data of the moving distance is sent to the output control unit 16, and the moving distance is sequentially displayed on the display 3, and the transparent keypad 1'
When the signal from section 2 is interrupted, the display 3 displays the distance traveled so far (actual JZ distance #t from point A to point B).

Next, the control operation of the CPU 15 during this time will be explained according to the flowchart shown in FIG. In step S1, “5.
When number key 5 of 0-OJ is pressed, C is pressed in step S2.
The PU 15 determines whether the key manual power is numerical key manual power or not.

In this case, if YES, the process advances to the next step S3 and resets the flag S that determines whether the start key has been input. Next, the process goes to step S4, and the data r500J is stored in the storage section RAM0 of the random access memory RAM. Next, the process advances to step S5, and after displaying the data of r500J on the display 3, the process returns to the first step Sl.

Next, when the start key 6 is pressed, the number keys are not manually operated, so the result in step S2 is No, and the process proceeds to step S6. Step S6 is a step in which it is determined whether or not the clear key 7 is input. If the clear key 7 is input, the process advances to step S7 and the memory sections RAM-0, RAM-1, RAM-2
Erase the memory of ``0°°'', reset the start key cassette flag, and return to step St. In this case, the clear key 7 has not been input, so proceed to step S8. In step 8, write tI In this step, it is determined whether or not the scale is stored in the RAM-0. If the scale is not stored, the process returns to step l. Since r5ooJ is written in RAM-o, step The process proceeds to step 9. In step S9, it is determined whether or not the manual input is from the transparent keyboard panel section 2. In this case, since the initial key 7 is input, the answer is NO and the process proceeds to step SIO.Step SI
At O, it is first determined whether key human power is required. In the case of No, the process returns to the first step 31. In this case, since the start key 7 has been input, the process advances to step Sll and the start key manual flag S is set. Next, proceed to step 12. In step S12, the scale data stored in the storage section RAM0 is transferred to RAM1-. i.e. r500J
The data is transferred from RAM0 to RAMI. After the transfer, the process returns to the first step Sl. Next, if you trace the transparent keyboard panel section 2''- along the map 17) from point A to point B, it will not be a numeric key, so the answer in step s2 will be No and the process will proceed to step S6. At step s6, since the input is not for clear gear 7, the answer is NO and the process proceeds to step s8. Since "r500" is stored in RAM0 in step 58-71, the answer is YES and the process proceeds to step S9. step s9
Since this is a transparent keyboard panel input, the answer is YES and the process proceeds to step 13. In step 13, it is determined whether or not the initial key manual flag S is set, and if No, the process returns to the first step s1. In this case, since the initial key input flag S is set, the answer is YES and the process advances to step S14. In step 314, the number of traced electrodes is added and the results are sequentially stored in the storage RAM2. Further, in step 15, the scale r500J stored in RAMI is multiplied by the number of electrodes stored in RAM2 at that time, and the result is stored in storage RAM3. Next, the process proceeds to step 16, where RAM0 is cleared, data from RAM3 is transferred to RAM0, and displayed on display 3.

Although the distance is outputted to the display device in the second embodiment, it may be outputted to a printing device.

Furthermore, it is of course possible to add a function as a normal calculator to the electronic device.

As described above, according to the present invention, the actual distance of a predetermined portion on a map can be accurately and quickly determined by an extremely simple operation.
