Description

  The present invention relates to an electronic device having a matrix operation function.

  Some conventional electronic desk calculators (hereinafter, simply referred to as “calculators”) have arithmetic functions such as calculus arithmetic and matrix arithmetic in addition to the four arithmetic operations. In order to perform a matrix operation with a calculator, matrix data is first input and stored, and the stored matrix data is read out.

  A dot matrix type liquid crystal display device is mainly used as a display unit provided in a calculator having a standard function, and its display area is limited to about a few lines. Therefore, it is necessary to input matrix data as follows.

  When inputting matrix data, first, the number of rows and the number of columns are input to define the size of the matrix, and then each element is sequentially input. The screen display when each element is input is displayed as “(1,1) =”, for example, in the case of the first row and the first column. , 2) = ”, and the input screen for the first row and the second column is displayed. When reading to confirm the stored matrix data, the element in the first row and the first column is displayed as “(1,1) = 1”, and this display is switched to “(1,2) = 2”. The elements in the first row and the second column are displayed, and are sequentially displayed up to the last input element.

  Thus, since each element is sequentially switched and displayed when data is input and when data is confirmed, it is difficult to confirm the size of the matrix and the position of the elements. In addition, in the case of addition or subtraction between matrices, the number of rows and the number of columns must match, but if the size of the stored matrix cannot be grasped, the number of matrices does not match and an error occurs. Will occur. Therefore, the user needs to remember the size of the stored matrix.

  In the matrix input device described in Patent Document 1, when the number of rows and the number of columns are set by operating the direction keys, the entire matrix corresponding to the set number of rows and columns is displayed on the screen using parenthesis symbols. Input of matrix elements is performed with the entire matrix displayed.

  In this way, the size of the matrix and the position of the input element can be confirmed by displaying the entire matrix.

  The layout display method described in Patent Document 2 includes a keyboard device for inputting characters, a character display device having display digits for one line, and a layout display device for displaying a document layout. In the layout display device, one segment is assigned to one character. When a character is input from the keyboard device, the character is displayed on the character display device, which corresponds to the position where the character of the layout display device is input. Turn on the segment.

The display unit 2 has a limited display area of only one dot matrix display row, or one dot matrix display row and one numeric display row. Here, the size of each dot in the dot matrix display row is preferably large enough to be visible. However, even in the case of a size that is difficult to visually recognize, the display unit 2 is not displayed in an enlarged manner or one element of the matrix is displayed as one dot through a device for enlarging display. If the cluster of dots is displayed as one element of a matrix, whether or not the size of each dot is visible does not impair the effect of the present invention. Furthermore, it is not necessary that the size of each dot is the same.

  An input unit 3 including a plurality of keys is provided below the display unit 2. The input unit 3 includes a power source / clear key 31 to be pressed when turning on / off the power and clearing an input numerical value, a cursor key 32 to be pressed when changing an input position, scrolling a display, etc. In the input of the numeric key 33 to be pressed when inputting numerical values, the calculation key 34 to be pressed when performing arithmetic operations, the edit key 35 to be pressed when shifting to the matrix data editing mode, the matrix data, etc. A data key 36 to be pressed when confirming a numerical value, a memory call key 37 to be pressed to shift to a call mode for a matrix data stored in a memory in a matrix operation or the like, and pressed to call a matrix data.

Key for an element value input means the key is provided for performing various operations, such as keys for key for trigonometric function operation, a regression calculation.

  FIG. 2 is a block diagram showing an electrical configuration of the calculator 1. The calculator 1 includes a display unit 2, an input unit 3, a VRAM (Video Random Access Memory) 4, a CPU (Central Processing Unit) 5, and a memory 6. The VRAM 4 stores display screen data of the display unit 2. The CPU 5 performs various calculations, writing and reading of each data to the memory 6, key input control from the input unit 3, writing of display screen data to the VRAM 4, transfer control of display screen data from the VRAM 4 to the display unit 2, and the like. And control the overall operation of the calculator 1. Further, a display control controller may be provided between the VRAM 4 and the display unit 2, and display screen data stored in the VRAM 4 may be transferred to the display unit 2 under the control of the display control controller.

  An address indicating a storage location of the VRAM 4 is associated with a coordinate indicating each dot of the display unit 2, and the CPU 5 writes a pixel value at a predetermined address based on the contents of the matrix data, which will be described later on the display unit 2. Perform layout display. When the display unit 2 can perform monochrome binary display, the pixel value is either “0” indicating white display or “1” indicating black display. When multi-value display is possible, the pixel value is a gradation value indicating brightness, and when color display is possible, the pixel value is a value indicating color and gradation.

  The memory 6 includes an edit matrix data area 61 for storing edit matrix data, an edit element position area 62 for storing edit element positions, a matrix memory A63 for storing matrix data, a matrix memory B64, a matrix memory C65, and a matrix memory D66. Matrix data storage means. Editing matrix data is matrix data that is being edited, such as when it is newly created for storage, or when an already stored one is modified, and has the same data structure (matrix size and matrix data as the stored matrix data). Each element value). The edit element position indicates the element position of the element value being displayed or input during editing of the matrix data.

  The matrix size setting means includes the input unit 3, CPU 5 and memory 6.

  FIG. 3 is a diagram illustrating a display screen example of the display unit 2. The display unit 2 has a dot display area 21 for displaying alphabets and symbols in various operations, and a segment display area 22 for displaying a numerical value mainly for a segment system. In the example shown in the drawing, the dot display area 21 can display up to 12 characters by 5 × 6 dots. Since the dot matrix method is a commonly used display method, the matrix size and element position can be easily displayed without using a special display method.

  FIG. 4 is a diagram illustrating a display example of the layout display. FIG. 4A is a diagram showing an example of a display screen of the display unit 2 when layout display is performed, and FIG. 4B is an enlarged view of the layout display area 23.

  As shown in FIG. 4A, the calculator 1 uses, for example, an area for one character (5 × 6 dots) in the dot display area 21 as a layout display area 23 that is a matrix position display area. Display. The layout display is displayed at the same time as the input screen for data such as element values, so that the user can select the matrix size of the currently edited matrix data and the relative position on the matrix of the element value being edited It is possible to input data while visually confirming “position” in some cases. Specifically, a rectangular dot block (simply abbreviated as “rectangular block”) in which the number of rows of matrix data being edited is the number of vertical dots and the number of columns is the number of horizontal dots is displayed in black. The element position being edited is displayed as a white dot in a rectangular block. For example, in FIG. 4B, since a 4 × 4 dot rectangular block is displayed in the layout display area 23, it can be seen that the matrix size of the matrix data being edited is 4 × 4. Since the dots at the positions of 2 dots from the left and 3 dots from the top are displayed in white, it is understood that the element position being edited is the element position of the third row and the second column. Further, as shown in FIG. 4A, in the dot display area 21 excluding the layout display area 23, “MAT” is used to indicate numerically that the element position being edited is the element position in the third row and the second column. 3, 2 = ”. Since the matrix set value display area is an area obtained by removing the layout display area 23 from the dot display area 21 and the segment display area 22, the matrix position display area is set smaller than the matrix set value display area. The position display area and the matrix set value display area are arranged in one display screen.

  The user can change the position of the element being edited by pressing the cursor key 32 while the layout is being displayed. For example, when the cursor key 32 → key (right key) is pressed once and the cursor key ↓ key (down key) is pressed once from the display state shown in FIG. As shown in FIG. 4, the display position of the white dots in the layout display area 23 changes to the positions of 4 dots from the left of the rectangular block and 3 dots from the top, and the dot display area 21 excluding the layout display area 23 has “MAT 4, 3 = ”is displayed, indicating that the element position being edited has been changed to the fourth row and the third column.

  By performing such layout display, even if the calculator has a limited display area, editing such as creating matrix data while checking the matrix size of the matrix data being edited and the element position being edited be able to. In addition, the size of the layout display area can be reduced as compared with the case where element positions and the like are displayed numerically.

A description will be given of a procedure for creating matrix data necessary for performing matrix operations and the like.
FIG. 6 is a diagram showing an operation procedure for creating matrix data. First, in the procedure A1, the editing key 35 is pressed and the cursor key 32 is pressed in a state such as a calculation mode for performing a calculation, thereby shifting to the editing mode.

  By shifting to the edit mode, the data of the edit matrix data 61 can be edited. The edit matrix data area 61 stores matrix data initialized by the initialization process of the calculator 1 or matrix data edited by the user last time. The operations performed in the subsequent procedures are reflected in the edit matrix data.

  In procedure A2, the number of rows is input to define the matrix size. As shown in FIG. 3, since “ROW =” is displayed in the dot display area 21 of the display unit 2, the number of lines is pressed by pressing the value number key 33 and inputting the number of lines, and then pressing the data key 36. Confirm. At this time, if the number of rows of the editing matrix data currently stored is different, all the element values of the editing matrix data are initialized to 0 as creating new matrix data.

  In step A3, the number of columns is input. As in the case of inputting the number of rows, “COLUMN =” is displayed in the dot display area 21, so the number of columns is pressed by pressing the value number key 33 and then the number of columns is determined by pressing the data key 36. . At this time, if the number of columns of the editing matrix data currently stored is different, all element values of the editing matrix data are initialized to 0 as a new matrix data is created.

  In step A4, an element value is input. The edit element position (initial position is, for example, the first row and the first column) is displayed in a layout, and the element values of the stored edit matrix data are displayed. When the value key 33 is pressed to input a numerical value, and the data key 36 is pressed, the element value of the edit matrix data is replaced with the input numerical value.

In step A5, the element position is moved. When the ↑ key is pressed, the element position line goes up by one, when the ↓ key is pressed, the element position line goes down by one, when the → key is pressed, the element position row goes to the right by one, and when the ← key is pressed Since the element position column is moved one place to the left, the value number key 33 is pressed to input an element value.
In step A6, the power / clear key 31 is pressed to end the editing mode.

FIG. 7 is a flowchart showing matrix data creation processing.
The editing matrix data and the matrix data stored in each matrix memory are composed of the number of rows R, the number of columns C, and element values m _{11 to} m _RC , and the editing element position is composed of the number of rows Ri and the number of columns Ci.

  This process starts from a state such as a calculation mode in which the calculator 1 is turned on and performs calculations. In step S1, it is determined whether or not the edit key 35 has been pressed and the cursor key 32 has been pressed. If pressed, the process proceeds to step S2, and if not pressed, the process waits. In step S 2, “ROW =” is displayed in the dot display area 21, and the matrix data initialized by the initialization process of the calculator 1 stored in the editing matrix data 61 or the matrix edited by the previous user is displayed. The value of the number of data rows R is displayed in the segment display area 22.

  In step S3, it is determined whether or not the value number key 33 is pressed and the row number X is input. If it is input, the process proceeds to step S4.

  In step S4, it is determined whether or not the number of rows R stored in the edit matrix data is the same as the number of input rows X. If they are not the same, the process proceeds to step S5, and if they are the same, the process proceeds to step S6.

The fact that the number of rows different from the stored number of rows is input means that new matrix data is created rather than correction of matrix data, etc., so in step S5, the initial value of the edited matrix data is displayed. Do. Initialization sets the input value X to a new row number R and column number C to 1, and sets all element values m _{11 to} m _RC to 0.

  In step S 6, “COLUMN =” is displayed in the dot display area 21, and the value of the number of columns C is displayed in the segment display area 22.

  In step S7, it is determined whether the value number key 33 is pressed and the column number Y is input. If it is input, the process proceeds to step S8.

  In step S8, it is determined whether or not the column number C stored in the edit matrix data is the same as the input column number Y. If they are not the same, the process proceeds to step S9, and if they are the same, the process proceeds to step S10.

The fact that the number of columns different from the number of stored columns is input indicates that new matrix data is created rather than correction of the matrix data, etc., so in step S9, the initial value of the edited matrix data is displayed. Do. In the initialization, the input value Y is set to a new column number C, and all element values m _{11 to} m _RC are set to 0.

  In step S10, the edit element position is set to Ri = 1 and Ci = 1. In step S11, the element values at the edit element positions Ri and Ci of the edit matrix data are displayed in the segment display area 22.

  In step S12, layout display is performed in the layout display area 23. In the layout display, assuming that one element corresponds to one dot, a rectangular block of R × C dot size is displayed in black, and dots at positions corresponding to edit element positions Ri and Ci are displayed in white. The CPU 5 calculates the coordinates of the pixels in the layout display area 23 based on the values of R, C, Ri, and Ci, and performs layout display by writing the pixel values to the corresponding addresses in the VRAM 4.

  In step S13, it is determined whether the value number key 33 is pressed and the element value M is input. If entered, the process proceeds to step S14, and if not entered, the process proceeds to step S15.

In step S14, the input value M is set as a new element value m _RiCi, and then the process returns to step S11 to display the input element value m _RiCi in the segment display area 22, and in step S12, the layout display area 23 The layout is displayed.

  In step S15, it is determined whether or not the cursor key 32 has been pressed. If pressed, the process proceeds to step S16, and if not pressed, the process proceeds to step S17. In step S16, a cursor movement process is performed, and the process returns to step S11. In step S17, it is determined whether or not the power / clear key 31 has been pressed. If it is pressed, the process ends. If not, the process returns to step S11.

  FIG. 8 is a flowchart showing the cursor movement process. If it is determined in step S15 of the flowchart shown in FIG. 7 that the cursor key 32 has been pressed, a cursor movement process is executed.

  First, in step S21, it is determined whether the ↑ key (up key) has been pressed. If it has been pressed, the process proceeds to step S24, and if not, the process proceeds to step S22. In step S24, the number of lines Ri at the editing element position is decreased by 1 (Ri = Ri-1). Next, in step S25, it is determined whether Ri = 0. If 0, the process proceeds to step S26, and if not 0, the process ends. In step S26, Ri = 1.

  In step S22, it is determined whether the ↓ key has been pressed. If it has been pressed, the process proceeds to step S27, and if not, the process proceeds to step S23. In step S27, the number of lines Ri at the editing element position is increased by 1 (Ri = Ri + 1). Next, in step S28, it is determined whether or not Ri> R. If Ri> R, the process proceeds to step S29, and if Ri ≦ R, the process ends. In step S29, Ri = R.

  In step S23, it is determined whether the ← key (left key) has been pressed. If it has been pressed, the process proceeds to step S30, and if not, the process proceeds to step S23. In step S30, the number of columns Ci at the editing element position is decreased by 1 (Ci = Ci-1). In step S31, it is determined whether or not Ci = 0. If Ci = 0, the process proceeds to step S32. If Ci = 0, the process ends. In step S32, Ci = 1.

  In step S33, the number of columns Ci at the editing element position is increased by 1 (Ci = Ci + 1). Next, in step S34, it is determined whether or not Ci> C. If Ci> C, the process proceeds to step S35, and if Ci ≦ C, the process ends. In step S35, Ci = C.

  In such a cursor movement process, even if an attempt is made to move the white display dot indicating the edit element position out of the rectangular block indicating the matrix size, the process cannot be moved outward.

  Next, a procedure for calling the matrix data stored in the memory 6 when performing a matrix operation or the like will be described.

  FIG. 9 is a diagram showing a calling operation procedure of matrix data. First, in the procedure B1, the memory call mode 37 is depressed by pressing the memory call key 37 and the matrix key 38 is depressed in a state such as the calculation mode for performing the calculation, and the mode is shifted to the memory call mode.

  In procedure B2, the size of the matrix data stored in the matrix memory A63, the matrix memory B64, the matrix memory C65, and the matrix memory D66 of the memory 6 is displayed.

  FIG. 10 is a diagram illustrating a matrix size display example of the matrix data stored in the memory 6. As shown in FIG. 10A, alphabets A, B, C, and D are displayed in the dot display area 21, and the matrix stored in each matrix memory in the size display area 24 on the right side of each alphabet drawing. Displays the matrix size of the data. For example, in FIG. 10B, since a 4 × 4 dot rectangular block is displayed in the size display area 24, it can be seen that the matrix size of the stored matrix data is 4 rows and 4 columns. In the display example of FIG. 10A, the matrix size of the matrix data stored in the matrix memory A63 is 4 rows and 4 columns, and the matrix size of the matrix data stored in the matrix memory B64 is 3 rows and 4 columns.

FIG. 11 is a display example when matrix data is designated. In FIG. 11, an example when the B key is pressed in the procedure B3 is displayed, and “matB” is displayed in the dot display area 21.

  In step B4, the power / clear key 31 is pressed to end the memory call mode. After the procedure B4, matrix operation can be performed using the called matrix data.

The matrix data includes a row number RD, a column number CD, and element values mD _{11 to} mD _RC .

  This process starts from a state such as a calculation mode in which the calculator 1 is turned on and performs calculations. In step S41, it is determined whether the memory call key 37 has been pressed and the matrix key 38 has been pressed. If it is pressed, the process proceeds to step S42. In step S42, in order to display the size of the matrix size of the matrix data stored in the matrix memory A63, the alphabet “A” is displayed in the dot display area 21, and the predetermined size display area 24 adjacent thereto is displayed.

If pressed, the process proceeds to step S53, and if not pressed, the process proceeds to step S54. In step S53, “matD” is displayed in the dot display area on the assumption that the matrix data stored in the matrix memory D66 is designated, and the matrix data stored in the matrix memory D66 is stored in the calculation data storage area (not shown). To remember.

  In step S54, it is determined whether or not the power / clear key 31 has been pressed. If pressed, the process ends. If not, the process returns to step S46.

  In the above, when performing layout display and size display, black and white binary display is performed. However, it is possible to identify the storage size of the matrix data being edited and stored and the element position being edited. That's fine. If multi-value display is possible, the gradation values of the dots indicating the matrix size and the dots indicating the editing element positions may be displayed as dots having different gradation values. If color display is possible, the dots indicating the matrix size and the dots indicating the editing element positions may be displayed in different colors.

  In the above, one element of matrix data is assigned to one dot and layout display and size display are performed. However, a plurality of elements such as two elements and four elements may be assigned to one dot.
