Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device having a statistical processing function such as a scientific calculator and a pocket computer, and more particularly to an electronic device having a function of inputting / storing / displaying weights of statistically processed data.

[0002]

2. Description of the Related Art Conventional examples of weighting statistically processed input data are shown in FIGS. FIG. 6 shows an example of weighting by a statistical processing software that stores input data.
FIG. 7 shows an example of weighting by a statistical processing software that does not store input data.

In FIG. 6, weight "1" is added to input data "12".
, And weighting the input data “3” with “5”.
(A) When statistical processing software without a weighting input function is used, X1 = 12, X2 = 3, X3 = 3, X4 = 3,
It is necessary to input the same data as the number of weights, such as X5 = 3 and X6 = 3. When (b) statistical processing software having a weighted input function is used, X1 =
When the [ENTER] key is pressed after inputting the data and weight such as 12, X2 = 3 × 5, the input data and weight are fixed, and X1 =
12, X2 = 3, X3 = 3, X4 = 3, X5 = 3, X6
= 3, data is stored by the number of weights.

On the other hand, FIG. 7 shows an example in which the input data "12" is given a weight "1", the input data "3" is given a weight "5", and the input data "64" is given a weight "0.978". . When inputting data and weight, the data is input in the form of “data × weight”, and then, when the [Data] key is pressed, the statistic is calculated as shown on the right side of the screen. Similarly,
When weighting “5” to the data “3”, “3 × 5 [D
data] ”and weighting“ 0.978 ”to the data“ 64 ”, the statistic is calculated every time“ 64 × 0.978 [Data] ”is input. In the case of a type of statistical processing software, statistics are calculated for each input of data and weight.

[0005]

However, in the above-mentioned conventional example, [1] the statistical processing software of the type that stores input data does not have a function of storing weights as data regardless of the presence or absence of a weighting input function. Therefore, input data must be stored by the number of weights, a large-capacity memory is required when inputting data with a large weight, and a small number of weights cannot be stored. Furthermore, the stored input data must be added or deleted when changing weights. On the other hand, [2] it is obvious that neither the input data nor the weight can be stored, and the weight cannot be changed, in the statistical processing software of the type that does not store the input data.

[0006]

An object of the present invention is to solve the above problems. An electronic device having a statistical processing function according to the present invention has a function of inputting a weight of input data, and the weight itself is stored / displayed as data. It is possible to change the weight data in the same manner as the input data. According to the first aspect of the invention, in the electronic device having the statistical processing function, the input of the numerical value and the cursor operation are performed. Means, a cursor position storage means for storing the position of the cursor, a cursor position detection means for detecting the position of the cursor at the time of inputting a numerical value by the cursor position storage means, and a cursor in response to the output of the cursor position detection means. When the position is at the input position of the statistical data, statistical data storage means for storing the numerical value input from the input means as statistical data, When Sol position is input position of the weight data, the weight data storing means for storing a numeric value input from the input means as the weight data of the statistical data,
Display means for displaying the numerical value input from the input means at the position of the cursor, and further, in the invention according to claim 2, the statistical data storage means or the weight data storage means is stored. A calling means for calling the statistical data or the weight data to the display means is provided.

[0007]

According to the present invention, in response to the output of the cursor position detecting means, when the cursor position is at the input position of the statistical data, the numerical value inputted from the input means is stored in the statistical data storing means as the statistical data, Display on the display means. On the other hand, in response to the output of the cursor position detection means,
When the cursor position is at the input position of the weight data, the numerical value input from the input means is stored in the weight data storage means as the weight data of the statistical data and displayed on the display means. Further, by operating the input means to position the cursor on the statistical or weight data called by the calling means and inputting a numerical value from the input means, the data is changed to store the statistical or weight data. Remember.

T, weight storage area W, cursor position storage area C A writable storage device RAM3 having a PT, an LCD driver 4 that controls the drive of the LCD, and an L that displays.
It is composed of a CD 5 and a KEY 6 for detecting a key input.

An input example of the input data and the weight of the input data will be described with reference to FIGS. 3 and 5. Here, as in the case of FIG. 7, an example in which the weight “1” is assigned to the input data “12”, the weight “5” is assigned to the input data “3”, and the weight “0.978” is assigned to the input data “64” Show. Input data is Xn
In the term (n = 1, 2, 3, ...), the weight is Wn (n = 1,
The weights are stored / displayed for each data. In FIG. 3, (a) when no data is input, the input screen for the first data is displayed,
The input data is in an input waiting state, and the weight is set to "1" unless input. → In this state, input data “1

→ The CPU 1 stores “W3 = 0.
978 ″ is stored. As described above, the input of the three input data and the input of the weight are confirmed.

The input procedure will be described with reference to the flow chart of FIG. 5. In FIG. 3A, the cursor is "X".
It is located at “=” of 1 = ”, so CPU1 is RAM
3 cursor position storage area C The current position of the cursor is stored in PT. In the state of FIG. 3A, if "12" is input from the numerical keypad (S1), the CPU 1 will
C of M3 It is determined whether PT is the position of weight (S
2). Since the cursor is now at the position of the input data, (N
O), the process proceeds to S4, and the input numerical data "X1 = 1"
2 ″ is stored in the statistical data storage area DT of the RAM 3.
Next, there is a numerical input in the state of (c) of FIG.
In this case also, since the cursor is at the position of the input data, the same processing as above is performed, and the input data "X2 = 3" is stored in the statistical data storage area DT. After that, the display is shown in FIG.
In this state, if the numerical value "5" is input (S1), the cursor is located at the weight position in S2 (YES), the process proceeds to S3, and "W2 =" is stored in the weight storage area W.
5 ”is stored. The above process is repeated thereafter.

Next, an example in which the weight "W2 = 5" of the input data "X2 = 3" is changed to "W2 = 100" will be described with reference to FIGS. When the second data screen of the input data is called, (a) the input data "X2 = 3" and the weight "W2 = 5" are displayed. → In this state, operate the cursor key to move the cursor to the weight position →
(B) CPU 1 is a cursor position storage area C of RAM 3
Store the cursor position in PT. → And, when you input the value "100" with the numerical keys, the weight "W2 = 10"
0 ”is displayed on the LCD 5. → Next, [ENTER]
When the key is pressed, (d) the CPU 1 stores “W2 = 100” in the weight storage area W of the RAM 3. Then, when the input screen is displayed, → (e) Certainly, the weight of the input data “3” is changed to “100”.

Also in the case of changing the weight, the position of the cursor is set to the cursor position storage area C as in the case of inputting the input data and the weight. The numerical value is stored in PT, the cursor position for inputting a numerical value is determined (S1 to S2), and the numerical value is stored in the statistical data storage area DT or the weight storage area W (S3 or S4). Here, the change of weight is described,
It goes without saying that the same is applied to the case of changing the input data.

[0015]

According to the present invention, not only the statistical data can be weighted, but also the statistical data and the weight data of the statistical data can be input / stored / displayed, respectively. You can see at a glance, there is no need to enter or store statistical data as many as the number of weights as in the past, key operation is reduced, a large amount of memory is unnecessary, and a small number of weight data storage Is possible. Since the data can be input / stored / displayed by the same operation as the statistical data without any difficult operation for the weight data, the weight data can be changed similarly to the statistical data.
