By mistake, not only the target key but also the adjacent key may be pressed at the same time. For this reason, the input person
We always judge in parallel with the data input whether there was any mistaken operation, and when we noticed the mistaken operation, we had to interrupt the input work once to delete the mistaken input data in order to correct that part. .

To address such a problem, for example, in Japanese Patent Laid-Open No. 12317/1990, when two adjacent keys are driven at intervals shorter than a certain interval, a visual or audible warning is issued. , A keyboard configured to prevent erroneous input of keys is disclosed. According to this keyboard, the data input person can easily be made aware of the occurrence of an erroneous input due to the simultaneous pressing of a key adjacent to the target key. Therefore, it is possible to prevent the input work from being continued without noticing the erroneous operation.

Embodiments of the present invention will be described below with reference to the drawings. (First Embodiment) FIG. 1 is a block diagram showing the arrangement of a data processing apparatus according to the first embodiment of the present invention. In FIG. 1, 1 is a keyboard, 2 is a main storage device, 3 is an input interval measuring means for detecting that two key inputs have been made by the keyboard 1 at intervals shorter than a preset time, 4
Is a key position discriminating means for discriminating whether or not two consecutive key inputs are caused by keys adjacent to each other, and 5 reads input data from the keyboard 1,
A data transfer device for transferring to the main storage device 2 and a pattern storage device 6 for storing a correct pattern of an input data string.

When the user mistakenly presses a correct key to be input and a key arranged adjacent thereto at one time, the input interval measuring means 3 inputs the interval between these two key inputs correctly. A key input interval to be determined as an erroneous input is set by focusing on a point shorter than the key input interval. This input interval is set to 100 ms, for example.

The key position discriminating means 4 holds information on the adjacency relation of the input keys arranged on the keyboard 1,
It is determined whether or not the two key input data detected as erroneous input candidates are input from input keys adjacent to each other. Next, the operation of the data processing device according to the first embodiment of the present invention will be described using the flowchart shown in FIG.

In FIG. 2, in step 100, the data transfer device 5 reads two data from the keyboard 1,
The first data is stored as PREV2 and the next data is stored as PREV1. Next, step 101
“Transfer PREV2” indicates that the data transfer device 5 transfers the first data PREV2 read in step 100 to the main storage device 2.

Step 102 "input data → INP"
Indicates that the data input from the keyboard 1 is stored in the data transfer device 5 as “INP”.
Step 103 "Interval with previous input?" Is a process of determining by the input interval measuring means 3 whether or not the time interval between the key input of the data read in step 102 and the key input immediately before it is 100 ms or less.

In step 104 "adjacent key?", It is determined that the interval between the input key read in step 102 and the key pressed immediately before it is 100 ms or less. 2
The key position determining means 4 determines whether or not two input keys are adjacent to each other. Step 105 "P
In “transfer REV1”, the data transfer device 5 transfers the data stored as PREV1 to the main storage device 2.

In step 106, PREV1 is set to PRE.
Move INP to V2 and PREV1 respectively. In step 107 “Pattern search” and step 108 “Correct data?”, The data transfer device 5 uses the pattern storage device 6.
It is determined which of PREV1 and INP is correct as the data following PREV2 by searching the stored data of.

In step 109, INP is PREV1.
Be moved to. After that, steps 100 to 109 are repeated until all data input is completed. The above operation will be further described using a specific example. FIG. 3 is an example of the arrangement of the keyboard 1 used in the following description, and it is assumed that Roman letters are input using this keyboard. Further, when there are two key inputs from the keyboard 1 at intervals of 100 ms or less, the input interval measuring means 3 detects these two key inputs as erroneous input candidates. Further, the pattern storage device 6 stores a correct input data pattern for inputting Roman characters. For example, the characters shown in FIG. 5 are stored as data that may follow “s”.

In the following, the place where the user should input "mojikensaku" from the keyboard 1
The operation when the input keys “a” and “q” are accidentally pressed at the same time and “mojikensqaku” is input will be described. Further, FIG. 4 shows a time interval of each key input. For example, the interval from the first "m" is pressed to the second "o" is 120 ms.
Is shown.

First, when "m" and "o" are input, they are stored as PREV2 (m) and PREV1 (o) respectively in step 100 of FIG.
Further, “m” is transferred to the main storage device 2 (step 1
01). Next, when "j" is input, it is stored as INP (step 102). Here, the input interval between "j" and the previous input "o" is 160 ms as shown in FIG. Therefore, the process is 1 according to the determination in step 103.
Move to 05.

Then, after transferring PREV1, that is, the "o" input previously, to the main storage device 2, step 10
In step 6, "o" is stored in PREV2 and "j" is stored in PREV1, and the process returns to step 102. FIG. 6 shows the step 10
2 shows the storage data of PREV1 and PREV2 when each data is read, and the data transferred to the main storage device 2 until the next input data is read.
For example, as described above, “j” is stored in PREV1 and “o” is stored in PREV2 at the time of reading the next data “i”, and “o” is stored between the reading of “j” and the reading of “i”. Is transferred to the main storage device 2.

With respect to the fourth input "i" and the fifth input "k" in step 102, since the intervals with the previous input are 140 ms and 160 ms, respectively, the same processing as in the case of "j" is performed, During this time, “j” and “i” are transferred to the main storage device 2. Next, when the sixth "e" is read (step 102), the interval between "e" and the previous input "k" is 80 ms, so step 1
The process proceeds to step 104 depending on the determination of 03.

In step 104, the key position discriminating means 4 discriminates whether or not "e" and "k" are inputted from the adjacent keys by referring to the adjacent key information. And
It is determined that "e" and "k" are not inputs from the adjacent keys, and the process is the same as the input data up to this point.
Then, the value "k" of PREV1 at this time is transferred to the main storage device 2.

After that, for the inputs of "n", "s" and "q", the intervals from the previous input are 140 ms and 120 m, respectively.
Since it is s, 120 ms, it is processed in the same manner as "j" above, and "e", "n", and "s" are transferred to the main storage device 2 during this time. Next, when "a" is read (step 10)
2) Since the interval between “a” and “q” of the previous input is 60 ms, the process proceeds to step 104 by the judgment of step 103.

In step 104, the key position discriminating means 4 judges that "a" and "q" are adjacent keys. Then, the data transfer device 5 determines that either "a" or "q" is an erroneous input, and searches the stored contents of the pattern storage device 6 (step 107). in this case,
The seven types of character strings shown in FIG. 5 are searched for as correct characters following the input “s” before “q”. Then, as a result of the search, it is determined that "a" stored as INP is correct and "q" is incorrect as the character following "s" (step 108). After that, the process proceeds to step 109, and the data “a” is stored in PREV1. However, in this case, the transfer to the main storage device 2 is not performed, and the process returns to the data input of step 102.

The same processing is continued for the subsequent input data, and as a result, "mojik" from the keyboard 1 is input.
For input "ensqaku", "mojiken"
Correct data "saku" is transferred to the storage device 2. As described above, according to the present embodiment, the input interval measuring means 3 for detecting the presence of two key inputs at intervals of 100 ms or less and two consecutive key inputs are generated by the adjacent keys. Key position discriminating means 4 for determining whether or not it is a data, a data transfer device 5 for reading input data from the keyboard 1 and transferring it to the main storage device 2, and a pattern storage device for storing a correct roman character input pattern. 6 is provided, and by the input interval measuring means 3 and the key position discriminating means 4, the adjacent keys are set to 10
When it is detected that the button is pressed at an interval of 0 ms or less,
Based on the Roman alphabet input pattern stored in the pattern storage device, the data transfer device 5 determines which of the two inputs by the adjacent keys is the incorrect input, removes the incorrect input data, and outputs only correct data. Main memory 2
By transferring the input data to, the erroneous input can be automatically deleted without interrupting the input work, and the input efficiency can be improved. (Second Embodiment) FIG. 7 is a block diagram of a data processing apparatus according to the second embodiment of the present invention. The data processing device shown in FIG. 7 differs from the configuration shown in FIG. 1 in that an input buffer 7 is provided between the data transfer device 5 and the keyboard 1.

The input buffer 7 sequentially receives and stores the input data from the keyboard 1. Then, the data transfer device 5 can also read from the input buffer 7 the data input after the data currently being processed. FIG. 8 is a flowchart of the operation of the data processing device according to the second embodiment of the present invention.

In FIG. 8, steps 100 to 107 and step 109 are the same as those in FIG.
08 is different from the case of FIG. 2 in that the process proceeds to step 110 when erroneous input data and correct data cannot be discriminated. In addition, Step 110 “Data prefetch”
Indicates that the data input after the data currently being processed are read ahead from the input buffer 7, and step 111
"Correct data?" Refers to a process of determining whether or not erroneous input data that could not be specified in step 108 can be specified by prefetching the data in step 110. The processing of steps 110 and 111 is repeated by prefetching the input data in sequence until the erroneous input data can be identified.

Further, as in the first embodiment, steps 100 to 111 are repeated until all data input is completed. Next, the operation will be described using a specific example. As in the first embodiment, the keyboard 1 is arranged as shown in FIG.
Shall be shown in. Further, it is assumed that the pattern storage device 6 stores the spelling of English words. Here, the case where the user should press "tribute" from the keyboard 1 by mistake, but presses the input keys "b" and "v" at the same time and inputs "tribvute" will be described as an example. Note that FIG. 9 shows the time interval of each key input as in FIG. 4.

The operation of the data transfer device 5 for each input of "t", "r", "i", and "b" is exactly the same as that of the first embodiment, and "t" and "r" are data transferred in step 100. For the “i” and “b” that are read by the device 5, the processes are performed in the order of steps 102, 103, 105, and 106, and when “v” is read (step 102),
"B" is stored in PREV1, and "i" is stored in PREV2.

When the processing for "v" starts, the input interval between "v" and the previous input "b" is 30 ms, and "v"
Since "and""b" are adjacent keys, the data transfer device 5 judges that either "v" or "b" is an erroneous input by the determination of step 103 and step 104, and the stored data of the pattern storage device 6 is determined. (Step 10
7).

Then, a candidate for a correct English word as shown in FIG. 10 is searched from the stored data as a word starting with "trib" or "triv". In this example, "t
Both words starting with "rib" and words starting with "triv" are present in the pattern store as correct English words. Therefore, it is not possible to specify which of "b" and "v" is correct input data. Therefore, depending on the judgment in step 108, the process proceeds to step 110.

In step 110, the data transfer device 5 prereads the input data next to the erroneous input candidates “b” and “v” from the input buffer 7. In this case, the input data following the currently processed data “v” is “u”. Then, in step 111, “tribu”
It is determined whether or not the character strings "trivu" and "trivu" correspond to the correct English word candidates shown in FIG. As a result, among the word candidates listed in FIG. 10, there are words that start with “tribu”, but there are no words that start with “trivu”.
Here, it is determined that "b" stored as PREV1 is correct and "v" is erroneous input.

This discards the data "v",
The process returns to step 102. Similar processing is continued for the subsequent input data, and as a result, “trivvute” is input from the keyboard 5 by “trivvute”.
The correct data “Bute” is transferred to the storage device 2. As described above, according to the present embodiment, the input interval measuring means 3 for detecting the presence of two key inputs at intervals of 100 ms or less and two consecutive key inputs are generated by the adjacent keys. A key position discriminating means 4 for discriminating whether or not it is a data item, a data transfer device 5 for reading input data from an input device and transferring it to the main storage device

Is provided. When the input interval measuring means 3 and the key position discriminating means 4 detect that adjacent keys are pressed at intervals of 100 ms or less, the data transfer device 5 is stored in the pattern storage device 6. Based on the spelling data of the English words, it is determined which of the two inputs by the adjacent keys is the erroneous input, and when it is not possible to identify which is the erroneous input data at this point, the input buffer 7 By identifying the erroneous input data by prefetching the data input after the currently processed data stored in the erroneous input data, only the correct data is transferred to the main storage device 2, As a result, erroneous input can be automatically deleted without interrupting the input work, and the input efficiency can be improved. (Third Embodiment) FIG. 11 is a block diagram of a data processing apparatus according to the third embodiment of the present invention. The data processing device shown in FIG. 11 differs from the configuration shown in FIG. 2 in that a plurality of pattern storage devices 6a and 6b are provided and an input mode instructing means 8 for instructing the current input mode is provided.
