Abstract

PROBLEM TO BE SOLVED: To surely perform the proof for a calculation by using an inhibition means which inhibits the subsequent inputs given from an input means if no equality is decided by a comparison means between the numeric value inputted to the input means and that inputted to a storage means. SOLUTION: An input part 11 inputs the numeric value and an operator. These inputted numeric value and operator are stored in a storage part 13 in response to the item count number showing the input position of the numeric value. When the arithmetic processing is carried out and then finished, it's decided whether a proof mode is selected next. If the proof mode is selected, the contents inputted in an arithmetic mode are inputted again via the input part 11. Then the inputted numeric value is compared with the numeric value of the item count number that is inputted in the arithmetic mode and stored in the part 13. If both numeric value are cat equal to each other, the input of an arithmetic key is permitted and the arithmetic processing is carried out. Meanwhile, the key input is locked if no equality is secured between both numeric value.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer capable of performing not only arithmetic but also verification.

[0002]

2. Description of the Related Art As a conventional technique, a computer having a check function is disclosed in Japanese Patent Application Laid-Open No. 6-35862.

According to the invention described in Japanese Patent Application Laid-Open No. Hei 6-35862, all the calculation contents of a computer are stored together with operators, and a verification key is input at the time of verification, whereby the operation contents are sequentially displayed in voice or display. If there is an error in the input, the correction can be temporarily interrupted with the correction key to perform the correction input, and thereafter the automatic verification can be performed subsequently.

However, in the above prior art, since the input contents are reproduced by voice or display, it is necessary to promptly confirm the input contents.
There is a problem that, overlooking it, it is not possible to correct incorrect input contents after all.

[0005] Further, when input contents are reproduced by voice, there is a problem that parts such as speakers and earphones must be added.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. Note that the present invention is not limited by this.

FIG. 1 is a diagram showing an example of a key layout of a computer according to the present invention. The slide switch 1 is a switch for switching between a calculation mode and a calculation mode, and the slide switch 2 is a switch for switching whether or not to perform printer output.

This computer has a numeric key 3 and an operation key 4 like a normal computer. Further, as keys unique to the present invention, a correction key 5 and an execution key 6 are provided.

FIG. 2 is a block diagram showing the configuration of a computer according to the present invention. In FIG. 2, the computer according to the present invention includes input means 11
And control means 12, storage means 13, display means 14, and printing means 15.

The input unit 11 is the various keys and slide switches described with reference to FIG. 1, the control unit 12 controls each unit, and the storage unit 13 stores the input contents from the input unit 11.

The display section 14 displays input contents and calculation results, and the printing section 15 prints input contents and calculation results.

FIG. 3 shows the contents stored in the storage unit 13 and the printing unit 15.
FIG. 6 is a diagram showing an example of the print content of the present invention. In FIG. 3, in addition to a numerical value and an operator as input contents,
An item count indicating the input position of the numerical value is stored in association with the item count. In addition, a numerical value, an operator, and an operation result are printed on the print content of the print unit 15.

FIG. 4 is a flowchart of the process according to the present invention. Normally, the operation mode is set (step S1).
A numerical value and an operator are input using the input unit 11 (numeric keys 3 and operation keys 4) (step S2). Then, in addition to the input numerical value and the operator, the storage unit 13 stores the item count number indicating the input position of the numerical value in association with each other.

Next, arithmetic processing is executed (step S
4) If the calculation is to be continued, the process returns to step S2, and a numerical value and an operator are continuously input. On the other hand, if the calculation is to be ended, it is next determined whether or not the verification mode is selected (step S6). If it is the verification mode, the contents input in the calculation mode are input again from the input unit 11.

First, a numerical value is input (step S7).
The currently input numerical value is compared with the numerical value of the item count number “1” input in the operation mode and stored in the storage unit 13 (steps S8 and S9). Execute the processing (step S1
0), returning to step S7, continuously inputting a numerical value, and this time comparing with the numerical value of the item count number “2”. This process is repeated by incrementing the item count.

On the other hand, if they do not match in step S9, the key input is locked (however, the input of the correction key 5 and the execution key 6 is permitted) (step S11).

When the correction key 5 is input (step S12), the numerical value input in the arithmetic mode and stored in the storage unit 13 is changed to the numerical value input in the verification mode, and the arithmetic processing is executed (step S12). Step S13), returning to step S2, and continuing the verification process.

If there is an input from the execution key 6 (step S14), an arithmetic process is executed using the numerical value input in the arithmetic mode and stored in the storage unit 13 (step S15).
Returning to step S2, the checking process is continued.

Next, based on the flowchart of FIG.
Another verification process will be described. Since the operation mode is normally the operation mode (step S21), the input unit 11 (numeric key 3,
A numerical value and an operator are input by the operation keys 4) (step S22). Then, in addition to the input numerical value and the operator, the storage unit 13 stores the item count number indicating the input position of the numerical value in association with each other.

Next, arithmetic processing is executed (step S2).
4) If the calculation is to be continued, the process returns to step S22, and a numerical value and an operator are continuously input. On the other hand, when ending the calculation, it is next determined whether or not the verification mode is selected (step S26), and if it is, the verification process is executed.

In this case, the calculation result in the calculation mode is output from the printing unit 15, and an input error location is found and corrected based on the output result.

First, when the item count number of the input error location is input (step S27), the control unit 12 displays the numerical value corresponding to the input item count number stored in the storage unit 13 on the call display unit 14. (Step S28).

Next, when a correct numerical value is input (step S29), the contents stored in the storage unit 13 are changed (step S29).
30) If there is any other input error, the process returns to step S27 to continue the verification process. If there is no other input error and the execution key 6 is input (step S32), the arithmetic process is performed using the corrected numerical value. Perform (step S33).
