PRT is a printing device, which is input by pressing αN to display display memory D in random access memory RAM, which will be described later.
The characters and numbers stored in M are printed on the βJ paper under the control of the print control signal CPFI from the control unit CPυ.

DIS is a display device consisting of, for example, a dot matrix type liquid crystal display, and is a control unit) Display control from CPIJ ■ Under the control of signal CDl5, it is stored in display memory DM in random access memory RAM, which will be described later. The above-mentioned letters Φ numbers are also stored in the random access memory R.
The Angline stored in the Angline memory ULM in the AM is displayed with an Angline attached according to the data of the additional digit.

Furthermore, the ROM is a read-only memory, that is, a read-only storage device, and when the control unit CPU sends the control #J signal to the printing device PRT and other external circuit devices,
A group of commands necessary to sequentially inform the control unit (CPU) of the procedure for sending out the control signal is stored.

In addition, the RAM is a randomly accessible storage device that stores the operating status of each circuit device, or stores input characters, numbers, etc. in an internal display memory area DM, and further stores it in an underground memory area ULM. stores the location where an underline should be added in the document being printed.

BUS connects control unit CPυ and read-only storage device RO
This is a pass line for transferring memory addresses and data between M and the random access storage RAM.

Next, regarding the operation of the electronic typewriter of the present invention having the configuration shown in the first figure, an input is made by key operation to the printing device PRT.
The explanation will be given with reference to FIG. 2, which shows an example of printing on a computer, and FIG. 3, which shows a flowchart of signal processing.

When this electronic typewriter is powered on in step 1 of the control procedure shown in the second figure, in step St of the flowchart shown in the third figure, the display memory area 11LM of the RAM is cleared, and the display memory area 11LM of the RAM is cleared. , a cursor pointer area in random access memory RAM.

CPM　“i　” is stored.

In the next steps S2 and S3, the character/numeric data in the display memory area OM is transferred to the underground memory area UL.

Executes a control loop that waits for the next key press while displaying the

Next, in step 2 of the control procedure shown in the second figure, when a key signal is input, for example, by pressing rAJ among αN keys, the process advances to step S4, where it is determined whether the pressed key or αN key is pressed. Determine whether or not. However, αN
If it is the key, the process proceeds to step S5, where it is determined whether it is the underground mode (enter y) or not (XX).

In the example of FIG. 2, the input by the above-mentioned press key rAJ is not in the underground mode, so step S
7, the character corresponding to the input key is stored in the display memory area DM of the RAM, and the cursor pointer is advanced to store 2' in the cursor pointer area CPM.

Next, among the controllers 1 tilted in the second diagram, the αN keys "B", "C", "D" and rEJ are pressed in the hand 1103.
When pressed in sequence, the above-mentioned control process of steps S2 to S7 in the flowchart shown in the third figure is repeatedly executed, and "'A, B" is displayed in the display memory area DM of the RAM.
, C, D, E"' are stored, and "6°°" is stored in the cursor pointer area CPH.

Note that when the Angline mode selection switch ULS has been selected in advance to Angline mode 183, the process advances from Step S5 to Step S8, and 1' is stored in the digit indicated by the power pointer in the Angline memory area ULM. Then, an angle line is attached to the input of the alphanumeric key αN sequentially. In this way, the operation when selecting the outline mode is the same as the conventional one.

Next, when the cursor left shift key is pressed in step 4, the process moves from step S4 of the above-mentioned control process in the flowchart shown in the third figure to step 312 via step S8, where the cursor left shift key is pressed. After confirming, the process advances to step 313.

In step S13, the cursor pointer is set to "'1".
At this time, the cursor ink area CPH stores 6° as described above, so the process proceeds to step S14, where the cursor pointer is counted down and the cursor pointer is counted down. 5'' is stored in the cursor pointer area CPH.

Finally, in step 5, press the cursor left shift key LSK.
When you press twice, the same control process as in step 4 is repeated twice and "3" is displayed in the cursor pointer area.

Furthermore, the process advances to step Sit, where the cursor pointer is incremented and the counted and deleted "4" is stored in the cursor pointer area CPM.

Next, in step 7, if you press the cursor right shift key again in the underground print mode,
As in step 6, the control process from step S4 to step S38 to step Sll is executed, and the underground memory area U[H is the memory content "00110" shown in FIG. 2.
At the same time, the memory contents of the cursor pointer area CPH are incremented to "5".

Next, when the carriage return key OR is pressed in step 8, the process proceeds to step 315 through steps S4, S8, and S12 in the above-described control process in the flowchart shown in the third figure. In this step S15, character strings rA, B, C, D are stored in the display memory area DM in the RAM.

E", perform printing as shown in Fig. 2 with the unlined line in accordance with the memory content "001100" shown in the second figure of the unlined memory area ULM, and then print the carriage return and line for one line. Run the feed. Next, the display memory and Angline memory areas UK, IJI, and M in the RAM are cleared, and the initial value "°1"' is stored in the Kahnle Point memory area CPH, and the series of control processes described above is executed. It will end once.

In addition, in the upper part, the cursor is shifted to the left end of the part to which an angline is to be attached, and the cursor is shifted to the right from that position while executing the angline processing, but the present invention is not limited to this example. Contrary to this example, the cursor may be shifted to the right end of the part to which an angline is desired, and the angline processing may be executed while shifting the cursor to the left from that position.

Furthermore, as a key for instructing execution of underground printing, in addition to the above-mentioned carriage return key, any desired function key, such as the country key or the logo key, may of course be used.

〔effect〕

As is clear from the above description, according to the present invention, in an electronic typewriter having an underground printing function,
