Description

Detailed Description of the Invention (Technical Field to which the Invention Pertains) The present invention provides a multi-purpose portable device that can individually calculate insurance premiums and various taxes for non-life insurance such as automobile insurance, fire insurance, and accident insurance. It is related to computers.

(Background of the Invention and Problems with the Prior Art) Conventionally, for example, an automobile insurance agent would constantly carry around a complicated quick reference table of insurance premium rates, etc., and would keep track of information such as the type of insurance selected by the customer, the method of payment, the type of car, the insurance amount, etc. Based on the above, each constituent value of the insurance policy was calculated by Fudebe or a portable electronic desktop calculator (hereinafter referred to as a calculator). Therefore, it takes a lot of time and effort to calculate the total amount of insurance premiums, and it is very troublesome to change various conditions and recalculate insurance premiums according to customer requests.

Therefore, in order to deal with such problems, it has been considered to use a portable general-purpose electronic aI calculator. However, in general computers, it is necessary to program each computer individually, and it is difficult to use the computer unless one has considerable knowledge about computers. In addition, insurance premium rates for such automobile insurance, etc. are often changed, and each time]
There was a problem in that a huge amount of data had to be re-entered.

For this reason, portable computers dedicated to various uses have been proposed, for example as seen in Japanese Unexamined Patent Publication No. 58-99583. However, such dedicated calculators require special function keys, and for example, in the case of a life insurance calculator, apart from calculating life insurance premiums, it can only have calculator functions (four arithmetic functions). There wasn't. On the other hand, insurance salespeople are often in charge of several types of insurance, such as life insurance, automobile insurance, and accident insurance. Therefore, in such cases, each person must carry multiple dedicated computers, which not only adds bulk to their belongings, but also increases the cost of purchasing them. .

(Object of the Invention) The present invention was made in view of the above circumstances, and its main purpose is to provide a portable device that can perform calculations for various purposes with simple operations. is to obtain a type calculator.

Another object of the present invention is to provide a small, light, and low-cost multi-purpose machine.

(Characteristics of the Invention) In order to achieve this object, the present invention provides a main body of the calculator with keys similar to those of an ordinary calculator and a liquid crystal display capable of displaying numbers, kana characters, etc. A cassette-type memory in which arithmetic programs and data corresponding to each calculation type are stored,
They are connected interchangeably. On the display, a question text is displayed for each question item, which can be answered manually using the numerical keys and confirmation keys, and data can be entered using the keys in the form of answering the question. The input data is then displayed on the display, and the user can proceed to the next step while checking the data.

Therefore, there is a low possibility of erroneous input, and it has the characteristics that it can be easily operated without a special manual or the like.

(Example) Hereinafter, the present invention will be described in detail based on the drawings.

There is. Further, the RAM 9 is used to temporarily store data. If the capacity of the internal RAM 9 is insufficient, an external RAM 12 is added to supplement this capacity. 1.11 This external RAM 12 may be mounted within the main body 1 of the machine, or may be connected to the outside via a case foot.

According to the basic program, the CPU8
Executes arithmetic processing while importing necessary external data via the 1-person capo-I, or exchanging data with the RAM 9, as necessary.
The processed data is output via the output port of the I10 boat 11. Human power of data touches human capo-1 °C
The data is output via the keyboard 2.
This is carried out by an LCD 3 of the type I/MANDUS type connected to the output port via an LCD driver J3. Further, a printer 14 can be provided as an option, and output data, for example, contract conditions and insurance premiums in the case of an insurance premium 41q machine, can be printed on a sheet.

Furthermore, a buzzer 15 is provided to generate an alarm sound to alert the user as necessary.

The cassette type memories 5, 5.5 are connected to the CP via the connector 6.
It is connected to U8, and the CPU 8 performs 1.1q according to the instructions in the memory 5. On the other hand, key manual operations are executed by a basic program in the internal ROM 10. Therefore, it is not necessary to operate the cassette type memory 5 while waiting for the key to be activated. Therefore, at this time, the power to the socket-type memory 5 is turned off via the transmission line 16 of the socket selection to reduce power consumption. When keys NM and ENT on the keyboard 2 are pressed, the power to the socket-type memory 5 is turned on, and the program in the memory 5 executes arithmetic processing.

In addition, by the cassette 7+- selection signal, one of the three cassette I-type memories 5, 5.5 is selected. This signal is switched between I) and J by operating the mode key MD. Therefore, if these memories 5 and 5.5 are used for car insurance, fire insurance, and accident insurance, respectively, by switching the mode key MD, calculation of those insurance premiums can be performed in one memory. It will be done using a computer.

FIG. 4 is a flowchart when a target calculation is performed using this computer. Here, as an example, a case will be described in which an insurance premium for automobile insurance is calculated. Note that p1 to p9 in the figure indicate each step of the flowchart.

Standard values are set as the data values input in advance in step p2. For example, the value is 50 million (yen) for personal damages, and 2,000 for property damages.
10,000,000 (yen), and there are no special contracts. In steps p3 and p5, data necessary for calculation is input. In this case, a question will be displayed on the LCD 3, and the input will be made in the form of an answer to the question. In the case of automobile insurance, human data such as vehicle type, fleet/non-fleet age requirement, amount of compensation for personal injury, amount of compensation for property, passenger insurance amount, presence or absence of various special contracts, no-accident discount rate, demerit premium rate, etc. are required. It is. Inputting such data can be done in four ways: (1) yes/no binary selection, (2) selection of one item out of multiple items, (3) numerical value, and (4) confirmation. I can do it. Therefore, a question for obtaining input data may be a sentence that can be answered in any one of these four types. These four types of answers can be made only by numbers from 0 to 9 and 'yes' or 'no'.

In steps p4 and p6, "OK" or "check pass" is input in order to confirm and correct the input data. In the case of "OK", press the confirmation key ENT, and in the case of "check", press any number key NM or function key FN other than the confirmation key ENT. If OK, proceed to the next step; if OK, go back to the previous step.

At step p7, necessary calculations are performed using the input data and the data table in the cassette type memory 5. The calculation result is displayed on the LCD 3 in step P8. In step P9, 1. Il! The results are printed by printer 14. Input data is also printed if necessary.

Next, the process returns to step p3 for displaying questions and inputting data. At this time, the initial setting routine is not passed. Therefore, for example, the initial value of personal compensation amount is 50,000,000 yen.
Then, the first question is “Taijin 5.QQQ
man?゛ is displayed. If you enter 100 million at this time, the next question will be “Taijin to, ooo man?”
” is displayed. This makes it easy to confirm input and make some changes.

Next, each data input method will be explained in detail.

(1) Two choices with yes or no - If yes to the displayed message, press the confirmation key E
Press NT and press the confirmation key ENT to import the displayed contents as data.

If no, confirm key other than ENT key NM or FN
Press. A different message will then be displayed. After checking, press the confirmation key ENT.

If the numeric key NM or function key FN is pressed before the confirmation key ENT is pressed, the displayed content changes each time.

FIG. 5 is a flowchart in the case of yes/no input. n is a variable and indicates a value of 0 or l. Xn is a character corresponding to variable n. For example, when explaining moped collateral, n=o indicates no moped collateral, and n+=
1 indicates that there is a moped collateral. And xO
No tampo'', press 1 x tampo ant°°
shall be. If n=0 in the initial setting in step S1, "°°Gentsuki Tampo Nashi°" will be displayed in Step S2. If yes, press the confirmation key ENT to proceed to the next step; at this time, n=0 remains. If no, press a key NM or FN other than the confirmation key ENT. Then, the message ``GENTSUKI TAMPO ARI'' is displayed. If yes, press the confirmation key ENT. At this time,
n=1. Confirm again key E N Key N other than T
When M and FN are pressed, the display returns to ``GENTSUKI Tambo NO''.If n-1 was inputted manually last time, the display starts with ``GENTSUKI Tambo ALL'' in step S2.

(2) At the beginning of the selection among multiple items, a title message is displayed, for example, ``Jash (
1 to 5)'' will be displayed. Based on the title message, press the specified number key NM (1 to 5 in this example).
When you select and press , the item name corresponding to that key NM (
For example, °゛Kokatajiyouyou'nato) is displayed.

While the name of the item you want is displayed, press the confirmation key E.
Pressing NT selects that item. Confirmation key E
Before pressing NT, you can press the number key NM as many times as you like, and each time you press it, the item name corresponding to the key NM you press will be displayed! ,'J changes. Furthermore, when a non-designated number key NM or function key FN is pressed, a title message is displayed. When the title message is displayed, pressing the confirmation key ENT will not be accepted. Once an item is selected, the title message table ir\ is omitted from the next time, and the selected item is directly displayed. From this point on, unless there is a change in the selected item, check the input data and press the confirmation key E.
Simply press NT to proceed to the next step 7.

FIG. 6 is a flowchart in the case of input by selection. n is a variable, 0, 1, 2. ..., take the count of N.

n=o indicates an unselected state. N is the number of selected items, and when using numeric keys NM from 1 to 8, N≦9. For example, if the selection is from ``3 terms +'', N = 3
It is. Xn is a character corresponding to variable n, Xo is a title display, and x1 to xn are item displays. for example,
In the case of car model selection, r+-0 means no car model is selected, n=
1 indicates a small passenger car, n=2 indicates a regular passenger car, n=3 indicates a light four-wheeled passenger vehicle, n=4 indicates a small cargo vehicle, and n=5 indicates a light four-wheeled cargo vehicle. do
xO as “°Jash (1~5)′”, X.

, x2 is "Fujiyoyou", x5 is "°°Key Kamotsu゛°". If n = 0 in the initial setting in step S1, then in step s2, the 5) '' is displayed.

When the number keys NM from 1 to 5 are pressed in step S3, the name of the corresponding car model is displayed. If “OK”, press confirmation key E
Press NT and if you want to change to another car model, press number key NM
Press again. Numerical keys NM and confirmation key EN from 1 to 5
When you press a key other than T, NM or FN, the first display (
Return to n=0) and encourage proper human power. If a car model was selected in the previous question, that car model name will be displayed from the beginning. Therefore, if there is no change from the previous one, you only need to press the confirmation key/ENT.

(3) Numerical input This is inputting specific numerical values, and like a calculator, the number key N
Use M (+/- keys and decimal point key if necessary) to place a number on the LCD 3J.

If you make a mistake, use the clear key to correct it.

After confirmation, press the confirmation key ENT to receive the numerical data.

(4) Display a confirmation message and input the confirmation key ENT as 7 in response.

FIG. 7 and FIG. 8 are flowcharts 1 and 2 showing an example of confirmation, respectively. As shown in FIG. 7, the title is displayed immediately after the program starts. When the confirmation key ENT is pressed, the process advances to the next step, and no other keys are accepted. Figure 8 shows interpersonal! υ"Here is an example where it is set that there is no limit if the amount of compensation exceeds 200 million yen. If a value exceeding 200 million yen is entered manually, the message ゛°Taijin J\Seigen゛° will be displayed, Request confirmation.

(Effects of the Invention) As is clear from the above description, according to the present invention, the questions displayed on the display can be answered using only numeric keys and confirmation keys, and the answers can be input from the keyboard. Since this allows input data to be taken in as input data, there is no need to provide special function keys, making it possible to create a simple and low-cost calculator.
By preparing several types of cassette-type memories in which calculation programs and data are stored, and by replacing the memories as appropriate, it becomes possible to perform various J'' calculations with one computer.

The content displayed on the display is changed using the numeric keys, and the content is imported as data by pressing the confirmation key, which has the following advantages.

0) Since the information to be entered is displayed, there is less chance of human error.

■ Manual data can be easily corrected before pressing the confirmation key.

- The function of the confirmation key is the same (meaning "OK") through the four types of input methods, and the other keys have no special meaning, so the operation is easy to understand.

■ Even in the selection method, each item is displayed, so there is no need for a special manual.

■ When re-checking input data, simply press the confirmation key and the input data will be displayed in sequence. To change the data, all you have to do is input the new data manually using the numeric keys while the data you want to change is displayed. Therefore, there is no need to perform any special operations to confirm or change input data.
