Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electronic typewriter that can be equipped with a plurality of pens to draw characters, graphs, etc.

BACKGROUND OF THE INVENTION Conventionally, pen-type electronic typewriters equipped with multiple ballpoint pens have been known. A pen, by using three types of erasable pens in exchange with the color pen, the characters printed with the erasable printing pen are erased with the erasing pen, and after erasing, the pen becomes non-erasable. The printer is equipped with a so-called erasing function for corrected printing, and when three types of erasing pens are attached and an erasing key is operated, the erasing operation is automatically performed. Furthermore, the erase key also had a function of erasing the content displayed on the display section of the electronic typewriter.

Although there are only 17 problems that the invention attempts to solve, in the above configuration, when the erase key is operated with a colored pen attached, the eraser key is located at the position where the erase pen should originally be attached. Characters are printed using colored pens, and there is a high possibility that an erroneous erasing operation will be performed.

Means to Solve the Problem According to the present invention, when erasing the displayed content on the display section, only the erasure key is operated, and the three types of erasing pens are attached to erase the printed characters. In some cases, a key other than the erase key (for example, a code key) is operated.

Function: With the above-described configuration, the present invention can prevent erroneous printing that occurs when the erase key is operated by mistake while a colored pen is attached.

Example An embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 shows a block diagram of the main parts of the configuration of the present invention. Fig. 2 is a perspective view of the electronic tie lighter of the present invention. Equipped with 6th grade. FIG. 3 shows a detailed diagram of the keyboard section 2.

The keys included in a general typewriter are arranged in the keyboard section. 2a is backspace, 2
b has forward etc., below delete 2C, return 2
d, space 2e, repeat 2f1 left margin set 2q1 right margin set 2h1 tab set 21, tab tariff 2 L margin release 2, tab 211 shift lock 2 m, shift 2n, reverse index 20
, index 2p1 color change 2q, code key 2r, and other character keys.

FIG. 4 shows a block diagram of essential parts of the present invention. In addition to the pen selection means 7, the printing unit 6 includes a line feed means 8 for moving the loaded paper in vertical lines, a pen left/right movement means 9 for moving the pen in the left and right directions, and a pen left and right moving means 9 for moving the pen on and off the paper. Characters are printed by a well-known method using a combination of a line feed means 8, a pen left/right movement means 9, and a pen up and down movement means 1o. The print data is still configured to be processed by the control section in accordance with key input from the keyboard section 2 and output to the printing section 6.

Further, FIG. 6 shows a configuration diagram of the printing section described above.

The pen left/right moving means 9 includes an X motor 18 and a gear 18a.

18b, 18C, a pulley 18d, a shaft 18e, and an 0-pull 1sf. When the X motor 18 rotates, rotational torque is transmitted to the gear 18 via gears 18a and 18b.
When the gear 18 rotates, the pulley 18
d and connected to the carriage 13, the lobe 18f is wound up. Therefore,
As the X motor 18 rotates, the carriage 13
can be moved left and right by sliding on the shaft 18e. In addition, the line feed means 8 includes an X motor 19, gears 19C, 19
b and a platen 21 connected to a gear 19b, and when the X motor 19 rotates, torque is applied to the gear 1.
It works to rotate the platen 21 via 9a and 19b. On the other hand, the pen vertical movement means 1° is composed of an X motor 20, a bush lever 22, and a cam (not shown) provided between the X motor and the bush lever.
0 rotates, the bushing lever 22 rotates and controls the contact between the pen and the platen 21 by suppressing or releasing the rear part of the pen mounted in the pen mounting hole 13b of the carriage 13.

Although not shown, a spring attached to the carriage 13 is configured to bias the pen in the direction of separating from the platen 21. Further, by rotating the pen holder 13 and changing the rotation angle of the two motors 20, the bush lever 22 is moved by the cam with a larger amplitude than when pressing the pen. Accordingly, the lever provided on the ring 13 is #f'lt,
The carriage 13 is configured to be rotated by using a gear portion 13c provided around the 1-kiyo rig 13. Further, 13a is a lever for taking out the pen from the pen mounting hole.

Next, the operation will be explained in detail using the main part flowchart (b) of the control section shown in FIG. Normally, when an input such as a character key is input from the keyboard section 2, the process proceeds to step 24, and if the position to be printed has already been erased, the indelible pen 16 is set in step 27, and at the same time, If no characters have been printed yet at the position to be printed, the process proceeds to steps 25-26, where the erasable pen 14 is set, and in step 28, characters corresponding to the above-mentioned keystrokes are printed. The printed content or the content erased after printing is stored in the typewriter processing at step 19 for at least 1 line/minute.

If the erase key 2C is operated after printing several characters, the process proceeds to steps 20 to 21. In step 21, it is determined whether the code key 2r is pressed, and if so, the process proceeds to step 22. In step 22, it is determined whether the current pen position is set to the erasing pen 16, and if it is set to the erasing pen 15, the current pen position is set to the erasing pen 15.
If a pen other than the erase pen 16 is set, the erase pen 16 is set in step 29. Then, in step 23, the same character as the erased character is automatically printed with the eraser pen 15 and erased. In this erase operation, after printing the erased character, the character is automatically backspaced by one character. It is well known. If the erase key 2C is input again, the process proceeds to steps 20-21 to 22 again, but this time, since the erase pen 16 is still set, the process immediately proceeds to step 22. characters will be deleted.

On the other hand, if the code key 2r is not operated in step 21, the process proceeds to step 3o, and the contents of the display section 3 as shown in FIG. 9a are erased as shown in FIG. 9b. Do the following. This operation is performed when the mode changeover switch 5 is switched to a mode in which input from the keyboard 2 is once displayed on the display section 3, and then when the return key 2d is operated, the displayed contents are printed. It is composed.

Although not shown, the code key can be used in conjunction with another key, such as 6C'', to operate the centering function.

Effects of the Invention In the present invention, when erasing characters printed using an erasing pen, the erasing key is operated while pressing the code key, and when erasing characters displayed on the display section, the erasing key is operated while pressing the code key. By configuring it so that only the keys are operated, it is no longer necessary to use the colored pen to erase and print over the i character, and the contents of the display can be erased only by using the erase key. Therefore, it is possible to realize an erasing function that is easy to use for the user.
