Abstract

PURPOSE:To delete a word registered in a dictionary memory without the reinput of the word by eliminating the last outputted word from the dictionary memory when a deletion key is operated in a stop state after outputting one word. CONSTITUTION:In the state where the printing action of registered words is stopped if the deletion key is inputted, a word stored in the address DIC(i-1) of a user dictionary memory 222, that is, only the last printed word is deleted and the area of the user dictionary memory 222 is arranged. And printing process mode becomes one word printing mode again. Thus the word can be deleted without being reinputted, so that the operation can be simplified.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a document creation device such as a Roman electronic typewriter or word processor.

[Prior art]

2. Description of the Related Art Conventionally, some document creation devices such as European electronic typewriters and word processors are equipped with a function to check the spelling of input words. A document creation device with such a function has a dictionary in which the spellings of words are stored in a storage device, and by comparing the word data stored in the dictionary with the input word data, the input word can be determined. This is to check the spelling of. Therefore, for spell checking to function effectively, it is necessary to create a dictionary that stores as many words as possible. However, if a large number of words are stored, the storage capacity increases accordingly, and since words that are used less frequently are also included, there is a problem that the efficiency of using the storage capacity decreases. Furthermore, the types of words used vary depending on the field of the document being created, and each field has special specialized words. Therefore, in addition to the dictionary memory created in advance, a user dictionary memory is provided in which the user can freely register and delete words.Words that are not registered in the dictionary memory in advance can be registered and One method is to create your own dictionary.

[Problems to be solved by the invention]

The contents of the user dictionary memory, which can be registered or deleted by the user, are output to a printing device, display device, or the like, so that the user can know the registered words. If an unnecessary word exists, the user erases the word from the user dictionary memory by inputting and specifying the unnecessary word again from the keyboard. in this way,
In conventional devices, the output of registered words and the deletion of registered words are completely independent processes, so when deleting a word from the user dictionary memory, first output all the registered words to mW, and then The problem was that the words had to be re-entered from the keyboard, making it difficult to use.

[Purpose of the invention]

The present invention has been made to solve the above problems, and its purpose is to enable words registered in a dictionary memory to be easily deleted.

[Means to solve the problem]

The configuration of the invention to solve the above problems is, as shown in FIG. A dictionary memory in which a plurality of word data for performing spell checking can be written and erased by an operator, and a control means for performing spell checking by comparing data input from the keyboard or the like with data in the dictionary memory. a word output control unit that outputs words stored in the dictionary memory one by one in a predetermined order from the output device based on a signal from the keyboard; and the word output control unit. In the stopped state after one word has been output by the section,
and a word deletion control section that deletes the last output word from the dictionary memory when the deletion key on the keyboard is operated.

[Effect]

Word data is input by operating keys arranged on the keyboard, and the input word data is spell-checked by the control means and then visually displayed by the output device to create a document. . Further, words are registered in the dictionary memory by the operator, and the words can be visually displayed by the output device. Every time a signal is output from the keyboard to the word output control section, the word output control section outputs the words registered in the dictionary memory one by one through the output device and visually displays the words. Then, in a stopped state after one word has been output, if the signal is input again, the next registered word will be output, but in this stopped state, it is detected that the erase key on the keyboard has been operated. Then, the word deletion control section deletes the last word displayed by the output device from the dictionary memory. In this way,
The words stored in the dictionary memory are output one word at a time according to the operator's operations and are visually displayed.
Deleted by operator command.

【Example】

The present invention will be described below based on specific examples. FIG. 2 is an external view of an electronic typewriter according to an embodiment of the present invention. A keyboard 1 having a large number of keys is disposed at the front of a case 70 of this typewriter, and a type impact type printer 30 as an output device 3 is disposed at the rear thereof. The mechanical part mainly consists of the platen 3
a printing mechanism including a printing hammer 32, a printing wheel 33, a printing ribbon cassette 34, etc.;
It is composed of a carriage moving mechanism that moves a carriage (not shown) equipped with a printing mechanism in the printing line direction. Further, in the printer 30, the printing position on the paper is controlled by driving the paper feeding mechanism and the carriage movement a mechanism in response to a signal from the control device C described later, and the printing position on the paper is controlled by driving the printing mechanism. Printing is controlled. Keyboard 1 has many character keys a and many function keys b
As part of the function key b, there is a print sub-dictionary key 12 that commands continuous output of registered words, which will be described later, and a stop key 13 that commands output of one word.
and an erase key 11 for commanding erasure of registered words. Further, a panel above the keyboard 1 is provided with a liquid crystal display 38 for displaying messages, input characters, registered words, etc. The control means 2, the dictionary memory 4, the word output control section 5, and the word deletion control section 6 are included in a control device C mainly consisting of a computer system shown in FIG. It is arranged on a printed circuit board (not shown). A central processing unit (CPtl) 20 that constitutes the control device C of the electronic typewriter is connected to the keyboard 1 via an input interface 23, and the input interface 23 is outputted from the keyboard 1 in response to key operations. It has a buffer register R into which a 1-byte key signal is input. The CPU 20 has an address bus, a data bus,
A ROM 21, a RAM 22, and input/output interfaces 24, 25, and 26 are connected to each other via a control bus. The ROM 21 includes a program memory 210 that stores a control program for inputting data from the keyboard 1, checking spelling, creating a document, and driving the printer 30 to print the document, and a program memory 210 that stores words in advance. A fixed dictionary memory 212 is formed. Also, RAM2
2 includes an input buffer 22 that reads and stacks data every time data is input to the buffer register R.
0, a line buffer 221 that stores output character data for one line, and a user dictionary memory 222 that allows the operator to freely register and delete words, and this RAM 22 is backed up by a battery. . Drive devices 80°, 82.84 are connected to the input/output interfaces 24, 25.26, respectively, and each drive device includes an LF motor 81 for paper feeding, a CR motor 83 for moving the carriage, and a printing motor. Hammer 32
A printing mechanism drive source 85 for performing impact, lifting and feeding of the printing ribbon, rotation of the type wheel 330, etc. is connected to each of the printing mechanism drive sources 85. Note that the drive device 80 and the LF motor 81 are electric means that constitute a part of the paper feeding mechanism, and the drive device 82 and the CR motor 83 are electric means that constitute a part of the carriage movement mechanism. The printing mechanism drive source 85 for the device 84 is an electrical means that constitutes a part of the printing mechanism. Next, the operation of the device of this embodiment will be explained. When a key on the keyboard 1 is pressed while the buffer register R in the input interface 23 is in an empty state, a code signal corresponding to each key is input to the buffer register R. When the input of the code signal is completed, the input interface 23 outputs a buffer full status signal and the CPU
An interrupt signal is output to 20. When this interrupt signal is input to the CPU 20, a predetermined interrupt routine is activated, the contents of the buffer register R are read, the data is stacked in the input buffer 220 formed in the RAM 22, and this interrupt routine ends. . Further, when the contents of the buffer register R are read, the buffer full status signal is reset, and the next key can be pressed from the keyboard 1. In this way, the keyed-in data is transferred to the input buffer 2 by interrupt processing.
20 are sequentially stacked. (a) Continuous printing of registered words In step St (hereinafter simply referred to as Sl. The same applies to other steps) in FIG. 4, the input buffer 2
One byte of data is read from 20, and in the next step 82, it is determined whether the input key data is print subdictionary key data or not. After other key processing is executed in S3, the CPU processing returns to Sl. On the other hand, if the input key data is determined to be print subdictionary key data in S2, printing processing for registered words 84 or less is executed. First, in S4, the initial value of the parameter [parameter] which determines the address of the registered word is set to 1. In the next step 85, the code data constituting one word stored at address DIC(i) of the user dictionary memory 222 is output to the line buffer 221, and then the printer 30 is activated and the registered word is printed. . Then, in S6, it is determined whether the number of printed words has reached the registered word number N, and if it has not yet reached it, the process proceeds to S7, where the parameter i is updated by 1, and in the next step 88, the next number from the input buffer 220 is The input key data is read. Then, in S9, it is determined whether the input key data is stop key data, and if it is other than stop key data (including when no data is stacked in the input buffer 220), the process returns to S5. Stop key 1 like this
If step 3 is not input, the printing process of the words registered in the user dictionary memory 222 is performed continuously, and the process proceeds to step S6.
When it is determined that printing of all registered words has been completed, the printing end process of S15 is executed, and the process returns to S1. ) Printing one registered word If the stop key 13 is pressed during the continuous printing process described above, the input key data is determined to be stop key data in S9 after printing one word, and the processes from 810 onwards are executed. executed. Sll-S14 is a routine for determining the type of next input key data. If it is not the corresponding input key data or if the data is not stacked in the input buffer 220, the CPU 20 will repeatedly execute the above routine until the corresponding key is input, and the printer 30 will stop printing. The situation is as follows. In this state, when the stop key 13 is pressed again, the determination in Sll becomes YES, and in S16, the next one registered in the user dictionary memory 222 is pressed.
The word printing process is performed. Then, in the next step 317, it is determined whether printing of all the registered words has been completed, and if the printing has not been completed yet, the step of updating the parameter i in 318 is performed.
Return to 10. Then, the routine from SIO to 514 is repeated until the next predetermined key power is received, and the state of the apparatus as seen from the outside becomes standby. In such a situation,
When the stop key 13 is pressed again, the next registered word is printed and the device is again in a standby state. In this way, each time the stop key 13 is pressed, the registered words are sequentially printed one by one. Additionally, if the number of printed words exceeds the number of registered words N during the above process, that is, the determination result in S17 is Y.
In the case of ES, the process moves to 515 and returns to the initial process 81 through the end process of S15. Further, if it is determined in S12 that the input key data is print subdictionary key data, the process moves to S5, and the print processing mode is changed from this one-word print mode to the above-mentioned continuous print mode. Further, if the input key data is determined to be end key data in S14, the end process in S15 is executed,
The CPU processing returns to the initial step 81. (C) Deletion of registered words When the execution steps of the CPU 20 are in the routines SIO to 314, this device stops printing the registered words, but if the erase key 11 is input in such a state, step S13 The determination becomes YES, and the process moves to 319, where the word stored at address DIC (i-1) of the user dictionary memory 222, that is, the last printed word, is deleted, and the area of the user dictionary memory 222 is deleted. Sorting will take place. Then, the process returns to SIO, and the print processing mode becomes the one-word print mode again. Through such a processing procedure, the user dictionary memory 222
The words registered at the end of R can be printed one by one and the words printed at the end of R can be deleted from the user dictionary memory 222 by operating the erase key 11. Therefore, since words can be deleted without having to be re-entered, operations become easier. Note that the functions of the word output control section 5 are mainly S10, S1
1, S16, S17, and S17.
This is achieved through a series of processing steps of the CPO 20 that executes the steps 19 to 19. Further, in the above embodiment, when the character key a is pressed and word data is input during execution of the routines 810 to 314, the word may be registered in the user dictionary memory 222. Further, in the previous embodiment, the printer 30 was used as an output device, but a display control circuit that controls the display of a display device such as a liquid crystal display 38 or a CRT display may also be used as an output device, and both of them may be output. They may be operated simultaneously as devices.

【Effect of the invention】

As described above, the present invention provides a document creation device having a dictionary memory for spell checking, which outputs the words stored in the dictionary memory one by one in a predetermined order to the output device, and outputs the words one by one. When the erase key is operated in the stopped state after the input, the last output word is deleted from the dictionary memory, so the words registered in the dictionary memory can be deleted without having to re-enter them, and the device Improves operability.
