Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character processing device capable of discriminating the accuracy of input characters. [0002] Conventionally, when practicing a type,
Regardless of English type or Japanese type (including Japanese word processor, etc.), while looking at the type exercise book,
It was customary to type the letters written there. However, in such a conventional practice method, it takes a lot of time to judge whether or not the typed character is correct, and in particular, accurate typing within a predetermined time limit is required. It was difficult to judge the speed and accuracy by counting the number of characters. Accordingly, an object of the present invention is to provide
An object of the present invention is to provide a character processing device which can recognize the correctness of input characters and practice typing. In order to achieve the above-mentioned object, a character processing device according to the present invention comprises an input means for inputting characters and a storage means for storing a specific character string. And a display unit for displaying a specific character string stored in the storage unit, and a character input by the input unit by the input unit of the specific character string displayed by the display unit. Detecting means for detecting whether or not it matches a character to be input, and when the detecting means detects a match, the identification displayed on the display means so that the character to be input next can be identified. And a control means for controlling so that the specific character string displayed on the display means is not scrolled when the character string is scrolled and the detection means detects that they do not match. It is those equipped. According to the above configuration of the present invention, when a character string input is incorrect when a specific character string is displayed on the display means to practice typing, the displayed character string is Since it is not scrolled, it can be recognized that it was not input correctly, and when the correct character is input, scroll the specific character string displayed on the display means so that the character to be input next can be specified Thereby, it can also be recognized that a correct character has been input. Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the present invention. In the configuration shown in the figure, KB is a keyboard, and includes alphanumeric keys AN such as AZ, 0-9, period, comma and type practice start key ST.
ART is provided. The CPU is a control unit composed of a microprocessor or the like, and includes a clock pulse generation circuit, a delay circuit,
It is configured in the form of a sequence control circuit having a gate circuit and other logic circuits (none of which are shown). DIS is a display device including, for example, a dot matrix type liquid crystal display, and is a control unit CPU.
Under the control of the display control signal CDIS from, a specific sentence such as a "proverb" which is a drill for practice is displayed, or a score indicating the skill of typing is displayed. The ROM is a read-only storage device, and stores a microinstruction group required when the control unit CPU supplies a control signal to each circuit device such as the display device DIS. The RAM is a randomly accessible storage device that stores the operating state of each circuit device, counts practice scores, and stores top scores. Further, in this embodiment, it is assumed that a large number of "proverbs" are stored in this RAM as a drill for practice. In addition, a display memory area (hereinafter, simply referred to as display memory) DM, which will be described later, is provided in the RAM. BUS is a bus line for transferring a memory address and data between the control unit CPU, the read-only storage ROM and the randomly accessible storage device RAM. TM is a timer for counting the time limit for practice. RG is a random number generator, and randomly selects one "proverb" from a large number of "proverbs" stored in the RAM based on the random number. Next, the operation of this embodiment shown in FIG. 1 will be described with reference to FIGS. FIG. 2 is a diagram showing the memory storage states and the display contents of the display DIS when the keys are operated. Also,
FIG. 3 is a flowchart (stored in the ROM of FIG. 1) showing the control procedure of this embodiment. First, in the procedure 1 shown in FIG. 2, when the power switch is turned on by the key operation, the entire storage device RAM is cleared in step S1 of FIG. After that, in steps S2, S3 and S4, when the display data in the display memory DM is displayed on the display device DIS, the time-out signal sent from the timer TM and any key is pressed. It goes around a loop waiting for a key input signal to be sent. Next, when the START key is pressed in step 2, the content of the flag F is detected in step S5. At the start, since F = 0, the flow shifts to step S6, and then the control shifts to step S7. In step S7, the score counter is cleared, the timer TM is instructed to count one minute, and then the flag F is set. In step S8, the start address of the randomly selected "proverb" is determined by referring to the table in which the start address of the practice "proverb" is stored, and the address data (for example, the present embodiment) is determined. In the example
701F (hexadecimal notation)) is stored in the load pointer. Here, in order to randomly select one "proverb" from a large number of "proverbs", one of the above-mentioned tables is selected according to the random number generated from the random number generator RG (see FIG. 1) described above. Just choose one. Next, in step S9, character data of 13 characters which is the number of displayable digits is loaded from the address indicated by the load pointer into the display memory DM. Then, the process returns to step S2 again. When the "N" key is pressed in step 3,
The control moves to steps S5, S10 and S11. Then, since the input character “N” matches the leftmost character “N” in the display memory DM, the control moves to step S12. In step S12, the contents of the score counter and the load pointer are incremented by one. Then, the control moves to a step S13. Here, since the input key is not the "." Key (period key), the process proceeds to step S9, the 13-character data from the address indicated by the load pointer is loaded again into the display memory DM, and the process returns to step S2. Display the data. As a result, the displayed character is scrolled to the left. Next, when the "Q" key is pressed in step 4, the control shifts to steps S5, S10 and S11.
However, in this procedure, since the input character "Q" and the leftmost character in the display memory DM do not match, step S
Return to 2. Therefore, the displayed characters are not scrolled. Thereafter, when the key operation as shown in FIG. 2 is performed in steps 5, 6, and 7, the same control as in step 3 is performed, and the display and other storage are performed as shown in FIG. The content changes. When the "." Key (period key) is pressed in step 8, steps S5, S10, S11, S1
2, control goes to S13. In step S13, it is detected that the input key is the "." Key, a new "proverb" is selected in step S8, and the start address is stored in the load pointer. In this embodiment, it is assumed that 42BC (hexadecimal display) address data is stored. Then, in step S9, the leading 13 characters of the new practice sentence "proverb" are loaded into the display memory DM, and thereafter, the process returns to step S2. When the key operation "Rome was" is performed in step 9, the same control as in step 3 is performed, and the display contents and the stored contents are changed as shown in FIG. When the time-out signal is sent from the timer TM (procedure 10), the control shifts from step S3 to step S14. Here, since the score counter data "29" is larger than the top score "0", the control shifts to step S15, and the score counter data "29" is stored as the top score. Then, in step S16, the score counter data "29" and the top score "29" are transferred together with predetermined comment data to the display memory DM, and the flag F is set.
Reset. Thus, in step S2, a display as shown in FIG. 2 is performed. As described above, according to the present invention, the character input by the input means matches the character to be input by the input means in the specific character string displayed by the display means. If the entered character is incorrect, the displayed character string is not scrolled, so you can recognize that you could not enter it correctly,
When the correct character is entered, the specific character string displayed on the display is scrolled so that the character to be entered next can be identified, and the correct character is also recognized. can do.
