Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a display type electronic calculator suitable for performing vertical and horizontal calculations.

[Prior Art] A conventional electronic calculator capable of calculating the length and width outputs the length and breadth data and calculation results processed on the RAM to a printing device. Therefore, the printing device is large, the price is correspondingly high, and there are also problems in terms of portability. Furthermore, since the printing speed of a printing device is generally slow, the apparent calculation speed is also slow accordingly. Furthermore, due to the reduction in total cost, the reliability of the printing device was not perfect and maintenance was required. Furthermore, the power consumed by having a printing device is much greater than the power consumed by a display-only calculator, so display-only devices cannot use solar cells that can be used as an independent power source, etc. There was a drawback.

[Purpose] The present invention has been made in view of the above-mentioned drawbacks of the prior art, and its purpose is to display necessary information and information by using a large display that can display data in multiple lines. The purpose of the present invention is to provide a small, high-speed, low-power consumption electronic calculator that is devised so that related information can be viewed at a glance.

The above-mentioned objects of the present invention are achieved, for example, by the configuration of functional blocks as shown in FIG. That is, key power means 1 for inputting data and functions, display means 4 capable of displaying information in multiple lines, storage means 3 for storing length and width information according to key power, and calculation means for performing predetermined calculations on the length and width information. 2, and a control means 5 for controlling the display and correction of a part of the information related to the vertical and horizontal calculations. Preferably, the storage means 3 stores larger pieces of vertical and horizontal information, and the control means 5 selects the desired part according to the key manual operation. The horizontal and vertical information of the image and the information of the calculation results related thereto are displayed simultaneously. The display means 4 is divided into a display area 41 for displaying vertical and horizontal information and a display area 42 for displaying calculation results. When there is a correction input to the display information in the display area 41, the display area 42 displays the related corrected information. You can see the calculation results at a glance.

[Embodiment] Hereinafter, an electronic calculator according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 2 is an external perspective view of an electronic calculator according to an embodiment of the present invention. In the figure,
Reference numeral 6 designates a battery as a power supply, 7 a large liquid crystal display capable of displaying data in multiple stages, and 8 a keyboard for inputting data and functions. The display screen of the liquid crystal display 7 is, for example, a display area 7 for displaying the progress of calculation execution.
1, digit and ? The purpose of use is divided into a display area 72 for displaying J8jW results. In addition to the various key switches necessary for performing normal calculations, the keyboard 8 also includes key switches 81 and 82 for controlling the scroll display function of the liquid crystal display 7, and key switches 82 for setting the machine to the vertical and horizontal calculation mode. and a key switch 84 used for controlling selection and display of some data during operation in the vertical and horizontal calculation mode.

FIG. 3 is a block diagram showing the main configuration of the electronic calculator shown in FIG. 2. Components that are the same as those shown in FIG. 2 are given the same numbers. In the figure, 9 is a microprocessing unit (MPU) that performs main control of the electronic calculator main body and arithmetic and logical operations, 10 is a ROM that stores programs executed by MPU 9, and 11 is information related to numeric values and vertical and horizontal operations. 12 is a display control circuit that drives the liquid crystal display 7.

In addition to processing procedures for performing various calculations in the normal calculation mode, the ROM 10 stores programs for processing procedures for performing vertical and horizontal calculations in the vertical and horizontal calculation mode. RAM area 11.
is a buffer register RR1 that stores the number of keys entered manually and function information in the order in which they were entered.
For example, 1 word (4 bits x 14) stores 10-digit numerical values and functions, and there is one that can store 10 digits, and general-purpose registers XR and YR used to execute various operations.
, ZR, and a register M a Y RF for storing flag information associated with various calculations. Other details of the hermitage will become clear from the explanation to be given later.6 Also, in the RAM fI area 112, matrix information of data arranged for vertical and horizontal calculations is stored. The display control circuit 12 has display registers DRI-DR6 corresponding to each display row of the liquid crystal display 7, and accesses the character generator CG under the control of the timing control circuit TC to display numbers and symbols in the display area 71. is displayed on 72.

FIG. 4 is an explanatory diagram showing details of the RAM area 112.

A relative column address and a relative row address are set as shown in the figure with reference to a predetermined address a of the RAM area 112.

For example, the address of column 1 and row 0 is indicated in the order of column and row, such as (i, o). Here address (1, 1), (N, l)
,(N.

A region 113 surrounded by a square including N) and (1, N) stores vertical and horizontal data, and addresses (1, O) to (N
, 0) is the total of the vertical data of each column, and the address (
o, 1) to (0, N) respectively store the total horizontal data of each row. Note that the RAM area 11.
has a memory capacity that is sufficiently larger than the information that can be displayed on the liquid crystal display 7 at one time.

In the above configuration, the operation in normal mode is performed in register
The content of the numeric value taken into R is displayed in the display area 72, and in this state, for example, when the "+" key is input, the 16 content of the register XR is added to the content of the operand register YR, and the result is transferred to the register ZR. Store in. The contents of register ZR are immediately displayed in display area 72, and a plus sign is added to the contents of register XR, and this is displayed in display area 71 as calculation execution progress information. The size of the display area 72 in the normal mode is one line, and the contents of the set numbers and the calculation results are displayed alternately according to the operation input. In this way, this machine also has the same benefits as those of a conventional calculator with a printing device or printing the calculation process on recording paper. Moreover, in this case, even if the display of the calculation execution progress overflows the display area 7□, information equivalent to the number of buffer registers RR, which is larger than this, is normally stored, so if the display overflows from the display area 7I. If you want to see the data,
For the cursor positioned at the top of the screen,
By pressing the "Home" key 81, the information in the display area 71 is scrolled down one line so that previous data can be viewed. If you want to return to the original state, display area 7
A reverse scroll display can be performed by further pressing the "ma" key 82 with respect to the cursor moved to the bottom line of □. These processes are executed according to a program stored in ROM10.

Now, the processing of the vertical and horizontal calculations becomes possible by turning on the rTYJ switch 83 for specifying the mode.

FIG. 5 is a flowchart showing the processing procedure for data manual calculation and display in the vertical and horizontal calculation mode. This processing is input by turning the rTYJ switch 83 to the ON side. In step S1, RAM areas 11□ and 112
Initialize the contents of.

In step S2, key personnel are in a waiting state.

If there is human power to press the key, the process advances to step S3 and it is determined whether or not it is a numeric key. If it is a numeric key, the process advances to step S4 and stores the numeric content in register XR.

If it is not a numeric key, the process proceeds to step S5, where it is determined whether it is a "+" key. If it is the “+” key, step S
Proceed to step 6 to perform normal addition processing. In other words, Zista XR
The contents of the numbers are stored in a predetermined address of the RAM area 112, and the totals of the vertical and horizontal data are calculated, respectively, for the vertical and horizontal data arranged in a matrix.
@l Store in the 0th column and 0th row of 12, and separately perform addition of the display column, store the addition result in the register ZR, and increment the contents of the item count register ICH by 1. In addition, display registers DH, ~DR5
Shift up the contents of by one line and transfer the contents of the register XR to the empty display register DR5,
The display register DR6 stores the contents of the addition result of the register ZR in the most significant digit of the item count register ICH.
Transfer the contents in a combined form. By combining and displaying the contents of item count register ICH,
The operator can immediately know the total number of vertical data items by displaying the calculation result. Furthermore, among the above-described processes, the former process is a process for calculating the vertical and horizontal directions in the RAM area 112, and the latter process is a process for notifying the operator of the calculation progress of the display column.

In step S7, it is determined whether the contents of the item count register ICH are equal to the contents of the register M a Y R. The register M a Y R is a register that stores the number of vertical data for one column through processing to be described later. Initially, it is initialized to O in step SL, and if the determination is NO, the process returns to step S2 and repeats the same process as described above for subsequent data in the same column. Further, a predetermined value is set in a process to be described later, and when the determination is YES, the process advances to step S8 and the contents of the register M a X R are incremented by one. In other words, move on to processing the next column.

Register M a X R is a register that stores the number of takes of horizontal data. In this way, the contents of the register MaXR are incremented by 1 each time one column of vertical data is input, and when the maximum column aN of the RAM area 112 is exceeded, the determination in step S9 becomes NO and the flow returns to the error handling routine. Proceed to step SlO. If the number is not exceeded, the process returns to step S2 and repeats the same row and column processing as described above.

If it is determined in step S5 that the key is not the "+" key, the process proceeds to step 311, where it is determined whether the key is the "=" key. "="
If it is a key, it indicates the end of addition of the data in the column, and the process proceeds to step 312, where it is determined whether the contents of the register M a Y R are equal to the contents of the item count register ICH. Initially, the contents of the register M a Y R are O due to the processing in step S1, and if an appropriate number of vertical data inputs are made, the item count register IC
The contents of H are appropriate integers. So step 3
The determination in step 12 becomes NO and the process proceeds to step 313. In step SL3, it is determined whether the flag M a Y RF is 0 or not. The flag M a Y RF is set when data is set in the register M a Y R in a process described later. Therefore, since this is also 0 at first, the flow proceeds to step s14, and if there is numeric data placed immediately before the "=" key manually, the same data processing as in step s6 described above is performed on it. In step S15, the contents of the item count register ICH are transferred to the register M.
Transfer to aYR. In step 316, the flag MaYR
Set the contents of F to 1. Step 3 mentioned above here
To explain the effect of the process No. 15, when the operator inputs data for vertical and horizontal calculations, the operator is free to decide whether to use one column as data for a row. That is, after inputting an appropriate number of data for the first column, by pressing the first "=" key, the item count number at that time is determined to be the number of data for one column. Therefore, from the processing of the next column, the number of data for one column will be automatically managed by the process of step s7 described above, regardless of the presence or absence of human effort using the ";" key. Step S1
In step 7, the contents of the item count register ICH are cleared in preparation for processing the next column. In step S18, the contents of the register M a X R are counted up by one. This is to move from the processing of the first column to the processing of the next column. The flow advances to Stella 7'S9 and register M is read in the same manner as above.
It is determined whether the contents of aXR are larger than a predetermined value N or not, and if it is smaller, the process returns to step S2. Furthermore, if the determination in step S12 is YES, this means that the number of data in the first column is one. The flow continues as it is at step 314.
Proceed to step 3 and perform the same processing as described above. In addition, from the processing of the next column, even if the "=" key is pressed midway, NO will be returned due to the flag M a Y RF being set in step S13.
is determined and the process returns to step S2. The contents of the item count register ICH and the contents of the register M a X R managed in this way are also used when arranging the data vertically and horizontally in the RAM area 112 in a matrix.

As the keys are manually operated as described above, the RA
The M area 112 stores vertical and horizontal data and the results of vertical and horizontal calculations, and at the same time, the display areas 71 and 72 display data related to the key operations and data of the calculation results.

FIG. 6 is a diagram showing monthly sales data by branch in tabular form. Regarding the data array shown in the figure, if keys are manually operated in order for each column from January to June, a similar data array will be reproduced in the RAM area 112, and each vertical and horizontal operation will be performed in the 0th column and 0th row. The results are stored. Next, a description will be given of a process for reading out the data of branches A to E in January on the screen and correcting the sales data of branch B from "5o" to "7o" for the data created in this way.

FIGS. 7(a) to (C) are diagrams showing the key operation procedure and display mode in this case, and FIG. 8 is a flowchart showing the processing procedure for partially displaying and correcting vertical and horizontal data. It is. The operation will be described in detail below with reference to both figures. To this process.

In the RAM area 112, enter the relative column address that contains the data you want to partially display, and then immediately enter r.
It is input by pressing the MAT J key 84. Figure 7 (a) shows the first number of human forces “1” followed by rM.
An example key operation procedure is shown in which the ATJ key 84 is pressed. Of course, multiple digits may be used as the number. In step S20, the number content rlJ of register XR is set to register
Move to s. Next, in step 321, the system waits for input of a number key to input a relative row address. In step S22, the second numeral content rlJ is taken into the register O is stored in the cursor position register CC indicating the display line position.Step S2
6, the contents of registers X s and Y s are set as column and row addresses of RAM area l12 from (Xs, Ys) to (
Xs.

The contents of the addresses sandwiched by Ys+4) are transferred to display registers DR, -DR5. The state of the display is shown in Figure 7 (
Shown in a). With this operation, the A of January shown in Figure 6 is
- Sales data of branch E was displayed. In step 327, the cursor is displayed at the northernmost digit of the display register DH(cc) indexed by the contents of the cursor position register CC. In other words, it is the left end of the top display line. In step S28, RAM area 112(1) address (Xs, 0
) That is, the content r of the vertical sum at address (i, o)
Transfer 1230J to display register DR6, step 5
At step 29, the contents "06" of the register M a Y H are transferred to the second two digits of the display register DR6 and displayed. If the "ma" key 82 is pressed once in this state, this is determined in step S30, and the process proceeds to step S35, where it is determined whether the contents of the cursor position register cc are smaller than 5 or not. If it is smaller, the content of the cursor position register CC is incremented by 1 in step S36 and the process returns to step S26. #ii! <
It will be seen that when the process passes through step S27, the cursor display line moves down one step. The state of this display is the 7th
It is shown in figure (b). If the determination in step S35 is No, the process advances to step S37 and the contents of the register Xs are incremented by one. It will be seen that the flow returns to step S26 and in subsequent processing the contents of the next column are displayed. In this way, the inside of the RAM area l12 is displayed in the display area 7.
1 + 72 can move freely. Also, step S31
8. If the input is determined, step 33
In steps 2 to 334, the reverse processing of steps 535 to S37 described above is performed. That is, in step S32 it is determined whether the contents of the cursor position register CC are greater than O, and if so, in step S33 the contents of the crab crane position register CC are decremented by one. If it is not larger, the contents of register Xs are minus 1 in step S34.
do. In other words, the contents of the previous column will be displayed. In step S38, the process waits for the subsequent input of the numeric key. In the example, the seventh
As shown in Figure (C) < r7J.

"0" is entered. If there is a numeric key input, this is taken into the register XR in step S39. Step 3
At step S40, the process waits for the subsequent input of the "+" key, and when the "+" key is input, the process advances to step S41. Hereinafter, in order to make the explanation easier to understand, the processing up to step 349 will be explained with reference to the flow and by substituting numbers according to the operations of the embodiment. In step 541, 7 dollars/s (0) of RAMm castle 11z.
