Abstract

PURPOSE:To understand at a glance whether a text exists in a memory or not by changing a display position of a text number automatically according to presence or absence of a data of the text when the text is called on a displaying means and the like. CONSTITUTION:When a text input key is inputted, a desired text number is inputted from a key board section 2 through a control means 11. Then, presence or absence of a data of the text number is detected and when the data does not exist, in a display means 3, a display of (a) display 1 is carried out, and the text number is displayed at a right side of the display. When there is a content of the text, a display of (b) display 2 is carried out. Further, in the case of an erasing and the like, the display of (a) display 1 is executed and in the case of an addition, a display of (c) display 3 is carried out. In this manner, when the text is called on the display means 3, and the processing such as the erasing thereafter, the addition is executed, a different display is executed according to presence or absence of the data of the text. Thereby, it can be easily understood whether a sentence exists in a memory or not.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention stores sentences (hereinafter referred to as texts),
The present invention relates to a display system for an electronic typewriter equipped with a text storage function (hereinafter referred to as text memory) that allows editing, printing, etc.

Conventional configurations and their problems Conventionally, some electronic typewriters have been equipped with functions such as storing input from the keyboard, editing, and printing.Many of these have been equipped with functions such as editing and printing. It can be called and displayed. However, in many typewriters, when the memorized content is displayed on the display, it is difficult to determine whether the memorized content is present or not.

OBJECTS OF THE INVENTION The present invention overcomes the above-mentioned drawbacks, and it is an object of the present invention to provide a display device in which it can be visually determined whether a text is in memory or not.

Structure of the Invention The present invention includes a printing means for printing characters, a text input key for entering the text memory mode, and a tl) f gist selection key for inputting the type of text with numbers 1 to 9. Each keyboard is equipped with a storage means for storing the contents of the text and a display means for displaying the contents of the text, and after entering the text memory mode by the text input key, the text selections 1 to 9 are performed. The desired text is displayed on the display means by pressing the key. At this time, if the specified text is not memorized at all, the specified number is displayed on the right end of the display means, and if the specified text contains any data, the specified number is displayed on the left side of the display means. The designation number is displayed on the screen, and the entire text is then displayed. FIG. 1 is a perspective view of an example electronic typewriter. Reference numeral 1 denotes a main body, including a keyboard section 2, a display section 3, a text character 4, a paper feed amount selection switch 5 at line feed, and whether or not characters input from the keyboard section 2 are displayed on the display section 3 (L/L).

It is equipped with 6 character keys as in a normal typewriter, each of which performs an operation according to nK.

FIG. 4 is a block diagram of the present invention. Although the printing means 8 is not shown, it is configured to print using a ballpoint pen, and a motor 9 after moving the ballpoint pen left and right moves the ballpoint pen left and right. A line feed motor 8 is used to move the attached paper up and down, and a pen up and down movement motor 10 is used to touch and release the pen from the paper to draw the desired character. Further, the 8 to 1o motors are controlled by a control means 11, and the control means 11 is controlled by a text driver 4 provided in the keyboard section 2.
It is configured to read the human power of each of the above-mentioned keys and cause the printing means 7 to perform an operation corresponding to the human power. The control means 11 is also connected to a storage section 12, and performs operations such as writing, recalling, deleting, etc. character data in the storage section 12, and causes the display section 3 to display the contents of the storage section.

Next, the present invention will be explained in detail using the main flowchart of the control means 11 shown in FIG. Normally, the program starts from the start 14 and processes the text detection 15, and performs general typewriter processing such as outputting the human power from the keyboard section 2 to the printing stage 7. . When it is detected in step 15 that the text input key has been pressed, the user is asked in step 16 which type of text to select. Here, 26 of keyboard section 2
Enter the desired number (text &) using the 2W keys. In step 17, the presence or absence of data for (1, the text) A is detected. If there is no data, display 1 is displayed in step 22. Display 1 is shown in FIG. 6a, where a text (in this example, 3 is designated) is displayed on the right side of the display section 3, and a character (in this example, 3 is specified) for distinguishing the text mA from the input character. ) will be displayed, followed by a cursor, indicating that there is no data in the specified text storage area.

On the other hand, if it is determined in step 17 that there is text content, the process proceeds to step 18, where a display like Display 2 shown in FIG. 6 is displayed. (In this example, the human power of each key is checked in advance in text memory mode, and the processing corresponding to each key is performed.

For example, if a character key is detected in step 19,
At step 24, the input character is added to the storage section.
Further, when it is detected in step 20 that the erase key 2c has been pressed, the target data in the storage section is erased in step 23. After these deletion and addition processes, the presence or absence of text content is determined again in step 25, and if all text content is lost due to deletion etc., a display like the above display 1 is displayed. If you add or add (if you enter a new character S or Z) 6th
As shown in Figure C, the display contents are shifted to the left and the 3'' display disappears as the manual input is performed.

Further, in step 21, when the text person 4 is detected again, the text memory mode is canceled and the process proceeds to the normal typewriter processing routine.

Effects of the Invention The present invention is a typewriter equipped with a text memory function that allows text to be stored, edited, printed, etc. When the text is called up on the display, and subsequent processing such as deletion and addition is performed. By automatically changing the display position of text)/[ according to the presence or absence of text data at the time, the user can see at a glance whether text is present or not. .
