Abstract

PURPOSE:To reduce the fatigue of an operator, by calculating the relative positions of pieces of characteristic information on the 1st operated key stored in the 1st storage part and characteristic information on the 2nd operated key from those pieces of characteristic information, and storing them in the 2nd storage part and performing processing. CONSTITUTION:When the operator depresses a desired key of a matrix key part 45 for the 1st time, pieces of characteristic information on the X and Y coordinates of the key are read by a microprocessor muPC42 and stored in the storage part 41 of a storage part 44. Then when the operator depresses one of adjacent upper and left, and left and right keys including the 1st operated key for the 2nd time, the muPC42 reads pieces of characteristic information on the X and Y coordinates of the key and subtracts the pieces of information in the storage part 41 from the read pieces of information according to the program in an ROM46 to obtain information on the position relation between the 1st and the 2nd operated keys, thereby specifying one display character of the matrix key part stored in a storage part 43 on the basis of the obtained information. Consequently, the operator inputs data with only his or her left or right preferable hand and even an unskilled operator inputs data easily.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a key matrix type data input device.

2. Description of the Prior Art Conventionally, a key matrix type data input device has a matrix key part 11 in which a plurality of keys are arranged in a wax pattern as shown in FIG. In general, a plurality of pieces of input information are displayed in an arrangement similar to the key matrix of the numeric keypad section 12. Note that FIG. 2 shows an example of the information displayed on one key 13 in FIG. 1.

In this example, when inputting the information ``Add'', the operator first presses the key 13 of the matrix key part 11 with his right hand, and then presses the key 12 of the numeral key part 12 with his left hand the second time. It is common to press ``4''. That is, the first operation of the key 13 indicates that the information "Add" belongs to the key 13, and the second operation of the key "4" indicates that the keys "1" to "9" of the numeric keypad part 12 are assigned. Sequence and similarity Ma) I
Among the nine pieces of information displayed on the J wax-like key 13, the user is instructed to input the information ``Add'' displayed at the position corresponding to the position of the key ``4'' on the numeric keypad portion 12. Thus, in this type of data input device, the right hand is used to operate the matrix key part 11 on which input information is displayed, and is used to move the range of the matrix key part 11 vertically and horizontally, while the left hand is used to operate the numeric keypad. In order to achieve a good data input speed when operating the scale 12, it should be placed exactly on the scale 12, and its relative position with the scale 12 should not move too much. was necessary.

In a two-handed data entry operation with such conditions,
Except for skilled full-time operators, there is naturally a limit to the amount of time required or the length of time that an operator can continue data input operations at a good speed without feeling pain or fatigue. In addition, if a beginner operates only with his or her dominant right or left hand, the matrix may be partially
1 and the number pad part 12 must be constantly moved back and forth, which is not only painful for the operator, but also has the disadvantage that there is a limit to the working time, and furthermore, the input speed is slow.

OBJECTS OF THE INVENTION It is an object of the present invention to reduce the pain and fatigue of the operator compared to conventional IJ wax data input devices, and to enable the operator to input data using only his or her dominant hand, either the right or left hand. The object of the present invention is to provide a key matrix type data input device which is capable of inputting data and is also suitable for beginners.

Structure of the Invention The present invention provides a data input device that has a plurality of keys arranged in an IJ wax pattern and in which a plurality of pieces of input information are displayed in a matrix on each key. A first storage unit that stores unique information regarding the key operated for the second time, unique information regarding the key operated for the second time, and information in the first storage unit 1 are calculated. a first means for generating information representing the relative positional relationship of the keys; and a second storage unit for storing a plurality of pieces of information displayed on each key in association with the information representing the relative positional relationship. , a second means for specifying and extracting one piece of information from the second storage section based on the information in the first storage section and the information representing the relative positional relationship; When a person operates a key on which the desired input information is displayed for the first time in order to input any one of the information displayed on the data input device, a unique information is stored in the first storage section, and then when any one key is operated for the second time, the first means stores the unique information regarding the key and the information stored in the first storage section. information, and generates information representing the relative positional relationship between the first key and the second key, and further, the second means calculates the information in the second storage unit and the relative positional relationship. The key matrix type data input device is characterized in that target input information is specified by extracting one piece of information from the second storage unit based on the information displayed.

Embodiments of the Invention Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 3 shows an example of a part of the matrix key in the first embodiment of the key matrix type data input device according to the present invention. In the figure, when inputting the information "Miyako" at 6-1, the operator first presses the key 22 ("Miyako").
``Miyako'', ``Tsu'', and ``Tsu'' are displayed), then press the key 21. Key 22. and key 23 respectively for "Miyako",
Assuming that the matrix parts correspond to ``tsu'' and ``tai'', press the key 21 corresponding to ``to j''. This completes the input operation for "Miyako". Similarly, to input "tsu", the key 22 is pressed the first time, and then the key 22 is pressed the second time. Also, to input "vs",
The key 22 is pressed the first time, and then the key 23 is pressed the second time.

FIG. 4 is an example of a part of the matrix in the second embodiment of the present invention. In the figure, when inputting "Miyako", the operator presses the key 33 for the first time, and then presses the key 31 for the second time. With this, the input operation for "Miyako" is completed. In this case, when the second key operation is performed, the key 31
．． Key 3? , key 34, and key 35 are regarded as matrix parts corresponding to "Miyako", "Tsu", "Tai", and "Oi", respectively.

FIG. 5 shows an embodiment of the data input device of the present invention having a part of the input/output interface illustrated in FIG. In the figure, 47 is a data bus, and the microprocessor 42
executes the microprogram stored in the microprogram section 46, and also executes the microprogram stored in the storage section 43.
In the matrix key, all the information displayed on some keys is arranged and stored so that it can be extracted arbitrarily based on the X and Y coordinates of the keys and their Y difference values. has been done.

Here, when the operator presses a key for the first time, unique X, Y coordinate information regarding the key is sent to the microprocessor 42.
reads it and stores it in the storage unit 41 in the storage device 44.

Next, when the operator presses a key for the second time without error, the microprocessor 42 reads the unique X, Y coordinate information regarding that key, subtracts the information in the storage unit 41 from this information, and then presses the key for the first time. As information representing the relative positional relationship between the keys and the second key, the result is: X difference - ○, Y difference difference knee 1
Or get +1. If we compare this result with the example in FIG. 3, we can see that: - If the key 22 is pressed the first time and the key 21 is pressed the second time, then the X difference = 0. Y difference=-1.

If the key 22 is pressed for the 11th time and also for the second time, the X difference=O, and the Y difference -0.

When the key 22 is pressed for the 11th time and the key 23 is pressed for the second time, the X difference is -0 and the Y difference is +1.

i, the microprocessor 42 extracts one piece of information from the storage unit 43 based on the information in the storage unit 41 and the information of the Y difference -1, Of +1, thereby performing the above two times. One piece of information input by key operation is finalized. Here, in correspondence with the example shown in FIG. 3 above, if the OY difference is -1, the input information is "Miyako".

- If Y difference = 0, the input information is "tsu".

・If the Y difference is -11, the input information is "pair" and is 9 - be.

Effects of the Invention According to the present invention, as explained above, compared to the conventional key matrix type data input device, the degree of pain and fatigue is less, and the operator can input data using only his or her dominant hand, either the right or left hand. This has the effect of realizing an IJ wax data input device (keyma) suitable for beginners.
