Thus, the equipment comes to more efficient, and the composition of the equipment can be simplified and inexpensive.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to electronic equipment, particularly electronic equipment that repeatedly performs a predetermined calculation using input operands and operands, adds data related to the calculation, and outputs the resultant data. It concerns equipment.

[Prior Art] Conventionally, electronic desktop calculators (hereinafter referred to as calculators) perform repetitive calculations (for example, AX B).
At the same time, the sum of the results of each operation is stored in the memory, and the sum of the operands (A for AXB) or the operands (B for AXB) is automatically stored in the specified memory, and then the appropriate key operation is performed. 2. Description of the Related Art Electronic devices that display or record and output the contents of their memory according to the information are known.

[Problems to be Solved by the Invention] In the above electronic devices, the data stored in a predetermined memory is fixed to either the operand or the operand.

For example, assume that in a certain device, the data to be stored in memory is fixed to the sum of operands and the sum of operation results.

In such a case, if the sum that the operator wants to obtain is the number of operands, the operator must add the operands for each operation using a separate memory in order to obtain the sum. This makes the work more complicated. This places a burden on the operator and also causes an increase in the cost of the device since a separate memory must be prepared.

In addition, if the operation is a commutative operation such as a product or a sum, the desired data can be added by reversing the input order of the operands and the operands, but in this case, information to switch the operators Processing is required. Normally, operators perform input according to the information on documents, etc., but in this case, they may have to perform manual input in the reverse order of the documents, which places a burden on the operator and causes problems such as incorrect input. be.

An object of the present invention is to solve the above problems and to enable the sum of operands or operands to be accumulated and output as desired.

[Means for Solving the Problems] In order to solve the above problems, in the present invention, a predetermined calculation is repeatedly performed using input operands and operands, and data related to the calculations are added and output. In an electronic device, a storage means for storing the sum of either the operand or the operand, and a means for specifying which sum of the operand or the operand is to be added to the storage means, When performing a predetermined repeated operation according to the settings of this designation means, either the operands or the operands are accumulated and stored in the storage means, and the summation data in the storage means is output in accordance with a predetermined operation. The configuration was adopted.

[Operation] According to the above configuration, the sum of the data of either the operands or the operands can be automatically added and stored according to the setting of the specifying means, and can be output as necessary. .

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings. FIG. 1 shows the structure of the operating surface of a calculator as an example of an electronic device employing the present invention.

In the figure, the reference numeral 1 indicates a keyboard, which includes a numeric keypad 1a, function keys 1b including four arithmetic calculation keys, an equal key 1c, and the like.

Further, in this embodiment, a storage switch 3 is provided for determining whether or not to store the operands or the sum of the operands and the sum of the calculation results in the memory for the manually performed calculations. Furthermore, a data designation switch 4 is provided which designates which of the sum of operands and the sum of operands is to be stored in the memory when the storage switch 3 is turned on. This switch 4 is constituted by an alternate switch, and specifies any of the above data depending on its specified state.

Also, the outfit shown in Figure 1! Here, there are two memory areas: an area (A) for storing the sum of operands or operands specified by the data designation switch 4, and an area (B) for storing the sum of the operation results. are provided, and data call keys 5a and 5b (A% B) are provided for respectively calling and outputting (displaying in this embodiment) the data stored in these memory areas.

Above the keyboard 1 is an LCD that can display multiple digits.
A display 2 such as an ED panel is provided. The display 2 can display and output input numerical values, calculation results, etc. by manually pressing the keys from the numeric keypad 1a and the function keys 1b.

FIG. 2 shows the structure of the control system of the device shown in FIG. In FIG. 2, reference numeral 1 is the keyboard shown in FIG. 1, and human input information from this keyboard is input to a CPU 11, which is comprised of, for example, a one-chip LSI.

In particular, input information from the data designation switch 4 of the keyboard 1 is determined via the determination means 12, and either the operand or the sum of the operands is stored in the designated sum data storage area 1ff(A) in the RAM 11c. is determined.

In addition, the CPU II is a ROM that stores the programs described below.
11b, arithmetic unit 11a1 and RAM for performing calculations;
11c.

The RAM 11c is used as a work area during calculations and a data storage area when memory is used, and has save areas lid and lle for temporarily saving operands and operands entered manually from the keyboard.

The RAM 11c also has an area 11g for storing the sum of calculation results when the storage switch 3 is turned on, and an area if for storing the operand or the sum of the operands specified by the data designation switch 4. have

The display 2 is driven by a display drive circuit 13 by the CPU II.
controlled via.

FIG. 3 shows the control procedure of the CPU II stored in the ROM 11b.6 Below, the operation of the apparatus shown in FIG. 1 will be explained with reference to FIG.

In step S1, the cpuit transfers data to be displayed to the display drive circuit 13 and displays it on the display 2. The display contents are determined by control described below.

Next, cpuz determines in step S2 whether or not a key force has been applied, and if no key force has been detected, the process returns to step S1.

If it is determined in step S2 that a key has been pressed manually, the process proceeds to step S3, where it is determined what kind of process is caused by the manually pressed key from the keyboard 1.

For example, if one of the function keys 1b (four arithmetic operation keys, etc.) is input, and it is determined that the process is to be performed in step S4, the input input is performed manually via the other key command processing routine in step 514 in the previous loop. The operand data is saved in the operand save area lid in FIG. 2, and the process returns to step S1.

Further, if the equal key is pressed manually, step S5
The process proceeds to step S14, in which the arithmetic operation data input through another key command processing routine is saved in the data save area lie shown in FIG.

Next, in step S6, arithmetic processing (four arithmetic operations, etc.) is performed according to the data and functions inputted from the keyboard 1 up to that point, and the results are transferred to the display drive circuit 13 and displayed on the display 2.

Subsequently, in step S7, the data save area lid
Then, the data saved in the data save area lie is added to the contents of the storage areas tif and l1g. This process is the fourth
This will be described later in connection with the figures.

In step S13, the data stored in the data storage area iff, 11g is transferred to the display drive circuit 13 according to the person's key and displayed on the display 2, and in step S1
Return to

FIG. 4 shows the process of step S7 in FIG. 3 in detail. First, in step S8, it is determined whether or not the data storage switch 3 shown in FIG. 1 is turned on. If the data storage switch 3 is not turned on, the process returns to the routine shown in FIG. 3 without doing anything. In step S8, if the data storage switch 3 is turned on, the calculation result obtained in step S6 is first added to the calculation result data in the data storage area 11g in step S9, and then stored in the same area again.

Next, the process moves to step S10, in which the data designation switch 4 determines whether the operand or the operand is designated as data to be stored in the data storage area 11f via the determination circuit 12, and the operand is designated as the data to be stored in the data storage area 11f. If the operand is specified, the process goes to step S11, and if the operand is specified, the process goes to step 312 for eight lines.

In step Sll, the arithmetic operation data in the data save area lie is added to the data in the data storage area 11f and stored in the same area again, and the process returns to step S1.

When proceeding to step S12, the data save area l
The operand data of id is added to the data in the data storage area 11f and stored in the same area again, and the process returns to step S1.

FIGS. 5A to 5P show the arithmetic processing when the data designation switch 4 specifies the calculation of the sum of the operands under the above control. The left side of each figure shows the input from the keyboard 1, and the right side shows the display state of the display 2 at that time. Note that before the input shown in FIG. 5 begins, each save area lid on the RAM 11c
, 11a and each storage area iff, fig are assumed to have been cleared using a clear key (not shown) or the like.

First, in order to store the data of each calculation manually performed in FIG. 5(A), the data storage switch 3 is turned on. Next, in FIG. Specifies to remember the sum.

Hereinafter, multiplication is performed three times (3×2.
9x4.8x6) a is repeated.

First, when the first operand is input in FIG. 5(C), the data is displayed on the display 2, and the second
The data is temporarily saved in the data save area lid shown in the figure.

Next, Figure 5 (D) shows the manual input of the function key, and Figure 5 (E) shows the manual input of the calculation number, its display, and the data saving area l.
When the equal key is pressed in FIG. 5(F), multiplication is performed and the result is displayed on the display 2. Here, since the data storage switch 3 is pressed down, the result of this calculation is stored in the data storage area 11g for summation of the calculation results. In addition, since the storage data designation switch 4 is set to store the sum of the operands, the data saved in the data save area lid is added to the data in the data storage area 11f, and then the data is saved again. Store in storage area iif.

Similar operations are repeated in Figures 5 (G) to (N) below.
The total sum of operands and the total sum of operation results are respectively stored in the data storage area 11f and the data storage area fig.

Then, when the data call key 5a is pressed in FIG. Further, when the data call key 5b is pressed in FIG.

On the other hand, FIG. 6 shows a case where the storage data designation switch 4 specifies that the sum of the calculation numbers be stored. Here again, a case is shown in which the same multiplication as in FIG. 5 is repeated three times.

When the equal key 1c is pressed in FIGS. 6(F), (J), and (N), calculations similar to those described above are performed, and the results of each calculation are displayed on the display 2.

Here, since we have specified to store the sum of the calculation numbers in FIG. 6(B), we add the data in the data save area 11e to the data in the data storage area 11f and then store it again in the data storage area if. Processing is performed. 6th
When the data call key 5a in Figure (0) is pressed, the sum of calculation results "90" is displayed as in Figure 5, but in Figure 6 (P
), the sum of the operands "1" is pressed.
2" is displayed.

According to the embodiment described above, when performing repeated calculations, the desired data of either the operand or the operand is specified by the data designation switch 4, the data is automatically added, and the total sum is displayed on the display 2. This has the advantage that there is no need to perform troublesome information processing such as memory transfer or exchanging data input order, compared to the conventional case where only one of the operands and the operands can be performed.

In addition, since the data storage area iff can be selected as the storage area for desired data, there is no need for a memory area to store unnecessary data as in the conventional method, which is efficient and allows the configuration of the device to be simple and inexpensive. It also has the advantage of being wrapped.

Although only multiplication has been described above, it can be used for the other four arithmetic operations, and similar techniques can be implemented for other operations, such as functional operations.

Further, in the embodiment described above, the data storage switch 3 and the data designation switch 4 are provided separately, but a single switch may also be used.

For example, as shown in FIG. 7, the switch 14 for storage control and data designation control is constructed from a slide switch having three setting positions.
It is conceivable that the setting state of a can be controlled to one of three states: one off state and two on states.

These two ON states of the switch 14 may be assigned to control whether the sum of the operands or the sum of the operands is stored, respectively.

That is, when the switch 14 in FIG. 7 is in the off state, control is performed so that nothing is stored in the data storage areas if and fig.

Further, in the first on state (ONl) of the switch 14,
The calculation result summation data is stored in the data storage area 11f, and
Control is performed to store operand sum data in the data storage area 11g.

Furthermore, in the second ON state (OH2), control is performed to store calculation result sum data in the data storage area 11f and calculation number sum data in the data storage area 11g.

Further, in the first embodiment, the data to be stored in the data storage area 11g is designated by the alternate type data designation switch 4, but this can also be realized by a momentary type key switch. In that case, the data designation switch I5 shown in FIG. 8 performs a toggle operation,
Each time the button is pressed, the operand or operand is set as memory storage data. This setting state can be identified by an indicator light 2a (or a display symbol, etc.) on the display 2.

In this way, the control method for the switch is arbitrary, and it goes without saying that various known control methods other than those described above can be used.

Moreover, although the embodiment of a calculator has been described above, it goes without saying that the above-described configuration is applicable to various electronic devices capable of at least repeating calculations and outputting calculation results.

[Effects of the Invention] As is clear from the above, according to the present invention, in an electronic device that repeatedly performs a predetermined operation using manually-generated operands and operands, adds and outputs data related to the operation, A storage means for storing the sum of either the operands or the operands, and a means for specifying which sum of the operands or the operands is to be added to the storage means, the specifying means When performing predetermined repeated calculations according to settings, either the operands or the operands are sequentially accumulated and stored in the storage means, and the total sum data in the storage means is output in response to a predetermined operation. Therefore, depending on the setting of the specifying means, the sum of data for either operands or operands can be automatically added and stored, and output as necessary. This simplifies operator operations compared to devices with fixed data, and eliminates unnecessary memory areas, which has the advantage of improving device operability and reducing manufacturing costs. be.
