Abstract

PURPOSE:To avoid the misinput with an electronic calculator by executing input of the continuous numerical values and the repeating frequency of these numerical values through a key part in an input state of the continuous numerical values so that the input of a necessary number of digits is possible. CONSTITUTION:When the continuous numerical values are included in the input numerical value, the presence of these continuous numerical values is supplied via a specific key and judged at a control part 12. Then the continuous numerical values if decided are transferred to an exclusive register 15 serving as a 1st storing means. At the same time, the continuous frequency of said numerical values is supplied to an exclusive counter 17 serving as a 2nd storing means. Then the numerical values are transferred to a register in an arithmetic part 14 in the counter input frequency. Thus an operation is carried out. In such a way, the input operation frequency is reduced and at the same time the misinput is avoided.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electronic desktop calculator, and in particular, when inputting consecutive numerical values, the key is to enter the consecutive numerical values and the number of repetitions of the consecutive numerical values. This invention relates to an electronic desktop calculator that allows input of the required number of digits by doing so.

[Conventional technology]

With conventional electronic desktop calculators, when inputting numerical values, it is necessary to input the input numerical values up to t times. For example, in 1,222,333, ``1'', ``2''
”, “2”, @2, “3”, “3#,” and so on.

[Problem that the invention seeks to solve]

In the conventional electronic desk calculator mentioned above, when inputting a numerical value, you press the key seven times to input all the numerical values, but there are some that require inputting three times each, such as '2'' and 13''. In this case, there was a drawback that the user entered the wrong number of keystrokes or entered the wrong keystrokes.

[Means for solving problems]

In the electronic desktop calculator of the present invention, when there are continuous numbers in the input numerical values, the controller inputs the continuous input numerical values using a specific key, the control unit determines that the input numerical values are consecutive, and if the numerical values are continuous, the first storage means is used. The number is transferred to a dedicated register, which is the numeric value, and the number of successive numbers of that number is input to the second storage means, which is a dedicated quanta.The number is transferred to the register in the arithmetic unit for the number of times input to the counter, and the calculation is performed. It is something.

[Example 1] The present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of a first embodiment of the present invention.

Normal numeric inputs are input multiple times through the key input section 11, and the data decoded by the control section 12 is transferred to the arithmetic section 14 and also transferred to the dedicated register 15, which is a first storage means. Next, in the case of continuous numerical input, input the numerical values from the key manual section 11, and as before, enter the numerical values from the calculation section 14. After being transferred to the dedicated register 15, which is the first storage means, the key input unit 11 inputs a key to determine whether the numerical values are continuous, and when the control unit 12 determines that the numerical values are continuous. When a consecutive number of times is input from the key input unit 11, the control unit 12 decodes that it is a consecutive number of times and transfers a value less than the number of inputs by ``'1'' to the counter 13, which is the second storage means. . While decrementing the inside of the counter 13, which is the second storage means, by '1#, the data in the dedicated register 15, which is the first storage means, continues to be transferred to the arithmetic unit 14 until MOH is reached. In addition, if the consecutive numbers include a decimal point, first transfer the number of consecutive integer parts to the counter 13, which is the second storage means, the number 1# less than the number of inputs, and then By pressing a key indicating a numerical value, the control unit 12 determines that the subsequent input numerical value is a consecutive number of digits below the decimal point, and the input numerical value is stored in a separate counter 1 by the second storage means.
Transfer to 7. First, counter 1, which is the second storage means.
The data in the dedicated register 15, which is the first storage means, continues to be transferred to the arithmetic unit 14 until the internal value of 3 is decremented by ``1'' until it reaches ``0'', and it is determined that the counter has reached ``0#''. At the time, the decimal point is transferred to the calculation unit 14, and then the data in the dedicated register 15, which is the first storage unit, is transferred to the calculation unit 14 until the content of another counter 17, which is the second storage unit, reaches “0”K. For example, 12,222
．． When inputting 22, first 1# is the normal input and is input to the calculation unit 1.
11# is transferred to the register in 4, and "1" is also input to the dedicated register 15 (step 1 in FIG. 3). Next, since "2" is a number with four integer parts and two decimal parts across the decimal point, "2'" is transferred to the register in the arithmetic unit 14 as usual, and the first It is also transferred to the dedicated register 15, which is a storage means (step 2).

Next, in order to input the consecutive number of times, the controller 12 presses the key °'α" to determine that the previously input numerical value is a continuous numerical value. Step 3) Press the same key again. The control unit 12 determines that the input of the consecutive number of times has ended. First, the number of consecutive integer parts "'4
``'' and save it to counter 1, which is the second storage means.
3 (step 4). Next, by pressing the key "β" indicating that the number of consecutive integer parts has ended (step 5), the next input data is the number of consecutive numbers of decimal parts, and inputs "'2#". It is transferred to another counter 17, which is a second storage means (step 6).The control unit 12 Then, 1 is subtracted from the data in the counter 13, which is the second storage means (step 7). A dedicated register 15 is a storage means for the apprentice.
The data in the counter 13, which is the second storage means, is transferred to the register in the calculation unit 14, and the data in the counter 13, which is the second storage means, is decreased by 1 until it reaches 0#.The data in the dedicated register 15, which is the first storage means, is calculated. The data continues to be transferred to the register in the unit 14 (steps 8 to 10). When the control unit 12 determines that the data in the counter 13, which is the second storage means, has reached “0”, the decimal point is transferred to the register in the calculation unit 14 (
Step 11) Then, the data in the dedicated register 15, which is the first storage means, is stored in the arithmetic unit 1 until the data in the separate counter 17 reaches 0'' in the second storage means.
Continue to transfer to registers in 4 (steps 12-13)
.

[Example 2] FIG. 2 is a block diagram of a second embodiment of the present invention.

As in the first embodiment, normal input data is inputted from the key human power section 11, decoded by the control section 12, and transferred to the calculation section 14. Next, in the case of consecutive numbers, first, the key human power section 12
Press the key to determine whether the next numerical value is a continuous numerical value, and if the control unit 12 determines that the numerical value is continuous, the data of the key 21 is stored in the first storage means. By pressing a key to determine that the continuous numerical value has ended, the number of consecutive numerical values to be inputted next is determined and transferred to the counter 27, which is a second storage means. A key indicating the end of the input number of inputs is input from the human power unit 11, and if it is determined by the control unit 12, the data in the dedicated register 23, which is the first storage means, is stored as many times as the counter 27, which is the second storage means. The data is transferred to the dedicated register 25 and then to the arithmetic unit 14.

For example, when inputting 2131313134, the first 2# is the normal number (Step 1 in Figure 4). Next, there are 4 consecutive numbers of "13", but first press the key "α" which indicates that the numbers from next onwards are consecutive (Step 2)
As a result, the control unit determines that the subsequent input numerical values are continuous, and the subsequent numerical value (113'') is stored in the dedicated register 23, which is the first storage means, instead of being transferred to the arithmetic unit.
13" is transferred to the next input (steps 3 and 4). By pressing the key 1α2" indicating that the next consecutive numerical value has been completed (step 5), the control unit 12 transfers the next numerical value (4# ) is determined to be the consecutive number of times, and input it to the counter 27, which is the second storage means (step 6). Key 1 to determine when consecutive number of inputs have been completed
α3” (step 7), the contents of the dedicated register 23, which is the first storage means, are transferred to the dedicated register 25.
Continue to transfer the contents of the counter 27, which is the second storage means, to 0'' until it reaches 0'' (steps 8 to 11). When the contents of the counter 27, which is the second storage means, is determined to be 60'', The contents are transferred to the calculation unit 14 (step 12). Next, input the normal input @4'' (step 13).

〔Effect of the invention〕

As explained above, the present invention saves consecutive input numerical values temporarily in a dedicated register and inputs the number of input values into a dedicated counter, instead of inputting all input numerical values. By inputting the beginning and number of inputs, all consecutive input numerical values can be input, which has the effect of reducing the number of input operations and eliminating errors in inputting the number of digits in consecutive inputs.
