DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a schematic hardware configuration of this embodiment, and FIGS. 2 and 3 are flowcharts each illustrating the operational flow of this embodiment. Further, FIGS. 4(a) to 4(d) are explanatory diagrams for explaining the operation of this embodiment on a display.

In FIG. 1, a key input unit 1 includes a character key 1a for inputting characters, a numeric key 1b for inputting numbers, a memo key 1c for setting a memo mode, a calculation key 1d for setting a calculation mode, and a calculation key 1d for arithmetic operations. Various calculation keys 1e and a return key 1f for searching data are provided, and information input through the key input section 1 is sent to a control section 2 that controls each section.

The control section 2 sets a flag for the processing mode instructed by the key input section 1 in the mode flag M2a, uses this flag to retrieve the execution program stored in the program memory 2b, and executes the processing in the instructed mode. It is. This control section 2 is connected to the following sections. A display unit 3 that displays input information, processing results, etc., and a data memory 4 that stores input memo data and processing data.
A R/W control unit 5 specifies a read/write position from a pointer 5a and performs reading/writing, and a numeric discrimination unit determines whether data read by the R/W control unit 5 is character data or numeric data. part 6, a BCD code converter 7 which converts the numeric code determined as a number by the numeric discriminator 6 into a BCD code; and a BCD code converter 7 which further stores the numeric data converted into a BCD code by the BCD code converter 7 in preparation for calculation. X・
A register unit 8 consisting of Y registers 8a, 8b and an operator register 8c for operators, and an arithmetic unit that has a predetermined arithmetic function and performs a specified operation based on the numerical data stored in the register unit 8. 9.

An example of the calculation operation of the information processing apparatus of this embodiment configured as described above in terms of hardware will be explained using data on the amount of expenses per person and data on the number of attendees at a certain year-end party stored in the data memory 4. An example of calculating the total cost will be explained with reference to FIGS. 2, 3, and 4. FIG. 2 is a flowchart of the calculation mode in this calculation process, and FIG. 3 is a flowchart of the numeric search process in the flow of FIG.

First, when the year-end party data is read from the data memory 4 and the display content on the display section 3 is as shown in FIG. The calculation mode is set by setting the mode flag M2a to 1. When in calculation mode,
In step A1 of FIG. 2, as shown in FIG. 4(b), the bottom row of the display section 3 is secured as a display area for arithmetic processing, and the register section 8 is cleared to enable arithmetic processing, and the next At step A2, the system waits for key input. When the return key 1f is operated in this step A2, it is determined in the next step A3 whether or not the return key 1f has been operated continuously. Naturally, the first operation is not continuous, so
In this step A3, the determination is No, and the process proceeds to step A4, where the contents of the X register 8a of the register section 8 are transferred to the Y register 8b. In this first operation, all registers in the register section 8 have been cleared in the previous step A1, so they are 0.
It has no meaning in terms of processing as it only transfers the data. When the process in step A4 is completed, the process proceeds to step A5, which is a numeric search process.

A detailed flowchart of the numeric search process in step A5 is shown in FIG. In this flow, when entering the numeric search process, R/
A read position pointer is set in the pointer 5a of the W control section 5 in step B1. Once the pointer is set, the data specified by the pointer is read character by character from the data memory 4 in step B2. In the case of this embodiment, data is read starting from "1" in December, which is the date of the year-end party, which is the beginning of the data. In the next step B3, it is determined whether or not it is the end of the data, and if it is not the end, step B4
It is determined whether it is a numeric code or a non-numeric code, and if it is a numeric code, the number read in step B5 is sent to the BCD code conversion section 7 and converted into a BCD code, and then the register section 8
This number is stored in the X register 8a. When the storage is completed, 1 is added to the pointer in step B6, and the process returns to step B2 to read the next data.

[0012] If it is determined in step B4 that it is not a number,
In step B7, it is determined whether it is a decimal point or another code, and if it is a decimal point, decimal point processing is performed in step B8, and step B
Proceed to step 6. Also, if it is determined in step B7 that it is not a decimal point, that is, in the case of a character or symbol, it is determined in step B9 whether or not the number has been imported, and if it has not been, the process proceeds to step B6 to read the next data. . If it is determined in this step B9 that the number has been taken in, and if it is determined in step B3 that the read data is finished, this number search process ends and the process returns to the original calculation mode process flow.

When the numeric search process is completed, the numeric data taken into the X register 8a in step A6 of the calculation mode process is displayed on the bottom line of the display section 3 as shown in FIG. 4(b). When this display ends, the process returns to step A2 and waits for key input.

[0014] The operator determines whether or not the displayed digits are necessary for the calculation. If the operator determines that the digits are unnecessary, the operator presses the return key 1f to execute a flow for displaying the next numeric data. This operation causes the membership fee amount of 9000 to be displayed in the calculation display area as shown in FIG. 4(c). Step A2 waiting for key input in this state
If a key other than the return key 1f is input in step A7, it is determined whether the pressed key is an input from the numeric key 1b or another key operation, and if it is another key, step A8 is performed.
It is determined whether it is the calculation key 1e or another key.

If it is determined in step A8 that it is the calculation key 1e, then in the next step A9 it is determined whether the operator has already been loaded and the calculation can be executed. If the calculation is not possible, in step A10, the operator inputted in step A8, for example, x, is fetched, and the process returns to step A2 to wait for the next key operation. In this embodiment, as shown in FIG. 4(d), the next number is searched by pressing the return key 1f, and 25, which is the personnel data, is displayed.

Step A waiting for key input in this state
2, when the = key of calculation key 1e is pressed, step A7
, A8, and A9, the x operator is input first, so the calculation is executed in step A11 and the calculation result is stored in the X register 8a. The stored calculation results are displayed in the calculation display area of the display section 3 through step A6.

[0017] When the membership fee amount of 9000 is displayed, for example, if you want to add 1000 yen to the membership fee, enter the operator + in step A8, and then enter 1000 from the number key 1b in step A7. . Next step 1
2, it is checked whether an operator has already been imported, and if an operator (in this case, the + operator) has been imported, the contents of the X register 8a, that is, 9000, are transferred to the Y register 8b in the next step A13. The number set in step A14, that is, 1000, is stored in the X register 8a, and the number 1000 is displayed on the display section 3 through step A6. After this, if you input the operator =, steps A8, A9, A
10 performs an addition operation.

[0018] Through this operation, the numerical data stored for memo purposes is utilized as numerical data for calculations.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be modified and implemented without changing the gist.

[0020]

According to the present invention, the range of use of information processing devices such as electronic notebooks can be expanded because numerical data input as memos can be utilized for calculations.
