Abstract

PURPOSE:To contrive reduction in side and cost, by a construction wherein data on the current position of a printing part are erased from a tab position memory part by depressing a key, and when the position of the printing part is not found in the data stored in the tab position memory part, the position data are stored into the tab position memory by depressing the key. CONSTITUTION:When a tab setting/clearing key 4 is turned ON, it is discriminated whether the current position of a pen is found in the data stored in the tab position memory part 12 in a controlling part 11. When the pen is not located at a tab position, the data of the current pen position are added to the data stored in the tab position memory part 12. On the other hand, when the current pen position is at a tab position, the position data are erased from the tab position memory part 12, thereby accomplishing a tab-clearing operation.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic typewriter having tab setting, tab release and tab operation functions.

Conventional Structure and Problems Conventionally, electronic typewriters have generally been equipped with tab functions as well as tab setting and tab release functions. In addition, although dedicated keys are provided for setting and canceling the tab, these two keys are not actually used at the same time, which increases the number of keys on the entire typewriter and increases costs. was.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned drawbacks of the conventional technology.
By using only one key for tab release (hereinafter referred to as tab sector or tab clear), it is possible to downsize and reduce the cost of an electronic typewriter.

Composition of the Invention The present invention includes keys for setting and releasing tabs, a keyboard for inputting characters, and a tab position storage unit that reads input from the keyboard and issues a print command to a printing mechanism unit that prints characters. a control section, when the position of the printing section is in the data of the tab position storage section, pressing the key erases the current position data of the printing section from the tab position storage section, and also erases the current position data of the printing section from the tab position storage section; When the position is not included in the data in the tab position storage section, pressing the above key causes the current printing section position data to be added to the tab position storage section and stored in the tab setting or cancellation key. This made it possible to unify the

DESCRIPTION OF EMBODIMENTS FIG. 1 is a schematic diagram for explaining the present invention, and FIG. 2 is a perspective view of an electronic typewriter according to an embodiment of the present invention. Reference numeral 1 denotes a main body, which includes a keyboard section 2 and the like. FIG. 3 is a detailed diagram of the keyboard section 2, in which the paper feed amount selection switch 3. Tab set clear key 4. Left margin set 6 degrees right margin cella) 6, 45 character keys, backspace 2a, forward 2b, erase 20. Return 2d, Margin Release 26. Tab 2f.

It is equipped with keys for shift lock 2g, shift 2h, repeat 21° space 2j, and index 2, and performs operations corresponding to each.

FIG. 4 is a block diagram of an embodiment of the present invention. Although the printing means 7 is not shown, it is configured to print using a ballpoint pen, and the pen is moved left and right to move the ballpoint pen left and right. A motor 9, a line feed motor 10 for vertically moving the attached paper, and a pen vertical movement motor 8 for touching and releasing the pen on the paper are used to draw the desired character. be. Also, 8 and 9 above
The motor 10 is controlled by a control means 11, and the control means 11 reads the tab set/clear key 4 provided on the keyboard section 2 and the human power of each of the above-mentioned keys, and prints the operation according to the input by the printing means 7. It is configured to perform the function of The control unit 1 is equipped with a tab position storage unit that stores data on the electronic tab position, and when the tab key 2f is operated, it detects the data on the tab position on the right side that is closest to the current pen position. It works like moving a pen to a certain position.

Further, when a tab is set by the tab set/clear key 4, the alarm means 13 is activated to notify the user that the tab has been set.

Next, the operation of this embodiment will be explained using a flowchart of the main part of the control section 11 shown in FIG. First, when it is detected in step 21 that the tab set/clear key 4 has been turned on,
The current pen position is the tab position storage unit 12 of the control unit 11
In step 22, it is determined whether or not the pen is on the tab. If the pen is not on the tab, the current pen position data is added to the tab position storage unit 12 in step 23, an alarm is sounded in step 24, and a new tab is set at the current pen position. to show that

On the other hand, when the current pen position is on the tab in step 22, the current pen position data is erased from the tab position storage unit 12 in step 26, that is, a tab clear operation is performed. .

Effects of the Invention The present invention is configured with one key for tab set and one for clearing tabs, and when the key is operated when a tab is already set at the position of the pen, it operates as a tab clear. This is configured so that when the key is operated when no tab is set, it will operate as a tab set, so the normally required two keys can be reduced to one, making electronic typewriters more compact and This can greatly contribute to cost reduction.
