Abstract

PURPOSE:To enhance printing efficiency and key input efficiency, by a method wherein a printing control means releases a break underline mode when a specific character printing mode is set and the specific character inputted by a key is printed without applying an underline. CONSTITUTION:CPU1 temporarily releases a break underline mode when the specific character printing mode order inputted from a keyboard 4, that is, a mode for printing only a specific character without an underline and printing a usual character in the break underline mode is inputted. Then, the specific character, for example, a comma or a period is printed without an underline and, thereafter, the break underline mode is again set. Because it is unnecessary to perform cumbersome key operation for setting and releasing the break underline mode at every printing of a specific printing mode, printing efficiency and key input efficiency are enhanced.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] This invention relates to an electronic typewriter that prints an underline on typed-in characters.

[Conventional technology]

Conventionally, devices of this type have been proposed that have a function of setting a play-underline printing mode, that is, a mode in which no underline is printed when a blank space is input.

[The problem that the invention seeks to solve]

However, when the break underline mode is set, for example, if a symbol such as "," or "," is entered, an underline will be printed in the same way, making it difficult to distinguish between an underline and a symbol. This results in an inferior text. Therefore, the operator must set the break underline mode for each symbol input.
This has had the problem of requiring extremely complicated key operations and significantly reducing key input efficiency.

This invention was made in order to solve the above problem, and when a specific symbol is input while the break underline mode is set, the break underline mode is automatically canceled and the specific character is The purpose is to obtain an electronic typewriter that can print without underlining.

[Means for solving problems]

The electronic typewriter according to the present invention includes a mode setting means for setting a specific character printing mode in which a specific character inputted by a key is printed in a normal printing mode while a break underline mode is set; A print control means is provided for canceling the break underline mode when a character print mode is set and printing a specific character input by key without an underline.

[Effect]

In this invention, when a specific character printing code is set by the mode setting means, the printing control means cancels the break underline mode and prints the specific character input by key without underlining.

〔Example〕

FIG. 1 is a block diagram for explaining the configuration of an electronic typewriter showing an embodiment of the present invention. 1 is a CPU serving as a main control unit, which controls each part according to a control program stored in ROM 2. control. The CPU 1 also serves as print control means of the present invention. 3 is a RAM, which is used as a work memory for temporarily storing various data. 4 is a keyboard for inputting character data and various mode commands (printing mode with underlining, break underline mode, specific character printing mode).

Reference numeral 5 denotes a printer, which sequentially prints character data input from the keyboard 4 under the control of the CPUI. 6 is a system bus that transmits various data to each part.

While setting the break underline mode, the CPU 1 receives a specific character print mode command input from the keyboard 4, that is, a print mode in which only specific characters are printed without underlining, and normal characters are printed in break underline mode. is input, break underline mode is temporarily canceled, the specific characters (in this example, comma "," and period ",") are printed without underlining, and after printing is completed, break underline mode is resumed. to be set. Note that the underline printing mode, break underline mode, etc. can be set by pressing a combination of keys on the keyboard 4.

Next, the printing control operation according to the present invention will be explained with reference to FIG.

FIG. 2 is a flowchart for explaining the print control operation according to the present invention. Note that (1) to (8) indicate each step.

The CPU reads the key information entered from the keyboard 4 (1) and determines whether the underline printing mode is being set (2). If the answer is No, that is, it is character information, it proceeds to step (8) and prints out the key-input characters. Print information for printing information is output to the printer 5, and characters are printed.

On the other hand, if the determination in step (2) is YES, it is determined whether the break underline mode is being set. 3)
, If No, proceed to step (7) to print an underline, if YES, determine whether the input key information is blank information (4), if YES, step (8).
), if NO, determine whether a specific character printing mode is being set to print the key information input in step (1) without underlining 5); if YES, proceed to step (7), and if NO If so, please judge whether the key information input in step (1) is a specific character, such as a comma "," or a period ","6), and if No, print an underline (7), and select YES. If so, print information for printing the key-input character information is output to the printer 5, and the characters are printed (8).

〔Effect of the invention〕

As explained above, the present invention includes a mode setting means for setting a specific character printing mode in which a specific character inputted by a key is printed in the normal printing mode during setting of the break underline mode, and a specific character printing mode using the mode setting means. We have provided a print control means that cancels the break underline mode when the character print mode is set and prints specific characters input by key without underlining.
While setting break underline mode, you can select printing without underline or with underline for specific characters, and you can also select to cancel the setting of break underline mode each time printing in a specific printing mode. Since there is no need to perform cumbersome key operations, it has the excellent advantage of significantly improving printing efficiency and key input efficiency.

Claims (4)

[Claims] (1) In an electronic typewriter that can select between a normal print mode in which key-input character information is printed without underlining, and a break underline mode in which character information other than blank information is printed with an underline, mode setting means for setting a specific character printing mode in which a specific character input by key is printed in the normal printing mode while setting the break underline mode;
When the specific character printing mode is set by the mode setting means, the printing control means cancels the break underline mode and prints the specific character input by key without underlining. electronic typewriter. (2) The electronic typewriter according to claim (1), wherein the specific character is a period. (3) The electronic typewriter according to claim (1), wherein the break underline cancels underline printing when blank information is inputted by a key.
