JPS63312181A - Correction method in electronic typewriter - Google Patents

Abstract

PURPOSE:To enable an efficient typing, by a method wherein a printing function of a printing mechanism is stopped, data for a character string to be corrected is registered to a correction memory, and with an input of a correction execution signal a printed character string is continuously corrected on the basis of the data for the character string registered in the correction memory. CONSTITUTION:By operating a back space key, etc., a hammer part 14 of a printing mechanism 11 is positioned either on the first character in a character string to be corrected or on the first character in a line having a character string to be corrected. Successively, a retrieval correction key is pressed to change-over an action mode of an electronic typewriter to a retrieval correction mode. After that, all the character string required to be corrected is inputted (registered) alternatively from the top character in the character string in order or from the top character of the line containing the character string to be corrected to the last character of the character string to be corrected from a keyboard 20 to a correction memory 22. Thereafter, a correction key provided on the keyboard 20 is pressed, whereby a character string required to be corrected is successively erased from the last character therein toward the top of the character string.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a collection method for an electronic typewriter having a collection memory.

(Prior Art) In electronic typewriters, characters input from the keyboard are generally printed immediately without going through steps such as editing and correction.For example, characters input incorrectly from the keyboard are immediately printed incorrectly. To correct this, mechanically print the printed paper with the same characters as the incorrectly printed characters through a film with concealing properties called correction tape or an adhesive film, and cover up the errors with the film. Methods of putting it away or peeling it off are known. In order to facilitate this correction work, electronic typewriters are equipped with a storage area called a collection memory, which stores the characters and locations to be corrected, but due to cost considerations, the storage capacity of the collection memory is limited. It is usually limited to a few lines from a 10-character wheel. To make corrections using correction memory, when you press the key that instructs correction, corrections are made almost automatically from the last character to the first character in the misprinted character string, but the correction memory To correct characters outside the range, move the printing mechanism to the correction location, press the key that instructs the correction operation, and print the same type of character as the printed character through the correction tape. conduct.

(Problems to be Solved by the Invention) However, the above conventional collecticon method has the following problems.

Correcting incorrect prints that have left the correction memory and is composed of multiple character strings requires a series of correction operations such as moving the printing mechanism, instructing the correction mode, and stamping the type for each character, which is troublesome. Proportional space printing, which causes mental and physical fatigue for users, requires accurate positioning of the printing mechanism for each character being printed, especially in proportional space printing where the horizontal spacing varies between prints. There is a problem in that this complicated operation takes time and significantly reduces the efficiency of the overall typing work.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a collection method that allows character strings to be corrected to be collectively registered in a collection memory with a simple operation and to be continuously collected.

(Means for Solving the Problems) In order to solve the above problems, the present invention has the following configuration.

That is, in the method of collecting printed character strings of an electronic typewriter, the character string to be collected is registered by aligning the printing mechanism with the collection function with the character string to be collected or the first character of the line containing the character string. Input a signal indicating this, stop the printing function of the printing mechanism, register the data of the character string to be collected or the character string of the line containing the data of the character string in the collection memory, and input the signal to execute the collection. The present invention is characterized in that printed character strings are continuously collected based on character string data registered in the collection memory.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows the main parts of the printing mechanism 11. Further, FIG. 2 shows a block diagram showing the structure of the electronic typewriter.

First, an outline of the functions of the electronic typewriter will be explained.

A mode changeover switch called a retrieval correction key is provided on the keyboard 20.

When the electronic typewriter is powered on or the system is reset, the mode is reset to the normal typing mode. When the retrieval correction key arranged on the keyboard 20 is pressed and a signal is input, the mode becomes the retrieval correction mode. When in retrieval collection mode, collection memory 2
The data No. 2 is cleared, and the state waits for character registration from the keyboard 20. If you want to return the set retrieval correction mode to typing mode, press the retrieval correction key again and input the signal to enable normal printing, but first press the retrieval correction key to switch the mode. The data of the character string is not returned to the seventh action memory 22, and the collection memory 22 is in a data clear state.

Keyboard 2 in retrieval collection mode
When registering a character string to be corrected from 0, the actuator 24c that drives the printing mechanism 11 performs an operation corresponding to the registered character, but the actuator 26 in the printing mechanism 11 does not operate at all.

The collection memory 22 stores all registered character string data until its capacity overflows, but if character string data exceeding its capacity is input, the collection memory 22 only stores the latest data for that capacity. , among the data input initially, the data input earlier disappears in order.

Since the printing mechanism 11 moves in one-to-one correspondence with the characters registered in the collection memory 22, it is easy to know which characters have been registered.

Next, a collection method according to the present invention for erasing character strings printed on paper will be described.

First, the hammer part 14 of the printing mechanism 11 is aligned with the first character of the character string to be collected or the first character of the line containing the character string to be collected by operating the backspace key or the like. If the positioning is insufficient, a good correction cannot be performed. Next, press the retrieval correction key to switch the operating mode of the electronic typewriter to the retrieval correction mode. Next, input all the character strings you want to collect from the keyboard 20 into the collection memory 22 in order from the first character of the character string, or from the first character of the line containing the character string to collect to the last character of the character string you want to collect ( register.

When the registration in the collection memory 22 is completed, the correction rank key provided on the keyboard 20 is pressed to execute the correction operation. The collection operation starts erasing from the last character of the character string to be collected and sequentially erases toward the beginning of the character string. That is, since continuous collection is automatically performed in the reverse order of registration starting from the last registered position in the collection memory 22, the burden on the user can be reduced and the time required for collection can be saved.

When all the character strings registered in the collection memory 22 are collected, or when the correction key is released and character data is input from the keyboard 20,
Immediately, the mode is automatically switched to the typing mode, and the data of the inputted character string is erased and printed by the hammer part 14 located on the blank paper surface.

Next, other embodiments will be described.

In the previous embodiment, all data in the collection memory 22 was cleared by switching the mode, but as shown in FIG. The method of the present invention can also be applied to an electronic typewriter in which a portion of the area 52 is used as an area for storing retrieval collection data only when the data is stored. Since this method does not clear all the contents of the collection memory, for example, if you want to continue deleting character string data in the collection memory range, you do not need to register it again, and the data will be automatically deleted based on the character string data in the collection memory. Automatic collection is possible.

Furthermore, the method of the present invention may be used in a system in which the collection memory 60 and the retrieval collection memory 62 are clearly divided as shown in FIG.

Furthermore, in the first embodiment, when registering the character string to be collected in the collection memory 22, all the actuators 26 in the printing mechanism 11 do not operate, but at least the marking actuator 28, which is a solenoid, As long as it is stopped, the actuators 24a and 24b in other printing mechanisms 11 may be operated.

Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. be.

(Effects of the Invention) When the collection method according to the present invention is used, the printing function is stopped and the data of the character string to be deleted is registered in the collection memory, so there is no duplicate stamping, so it is easy to identify the character string to be deleted at the time of collection. can be erased.

In other words, it is possible to use normal or more compact collection memory and add new frequently used functions.

In addition, compared to conventional manual collection, the steps of adjusting the printing mechanism for each character of the character string you want to collect, setting the collection mode, and stamping the same type of characters as the characters to be collected are no longer necessary. Lines containing character strings can be registered consecutively in the collection memory in the same way as normal typing, allowing for efficient typing work. Note that the collection method according to the present invention has remarkable effects such as being able to perform the collection more effectively in proportional spacing printing.
