Abstract

PURPOSE:To put automatically underlines by clearing the storage set by a setting means which puts underlines to printed characters when the line feed and tab position data are read out of a text memory. CONSTITUTION:A CPU50 uses a temporary storage function of an RAM58 and at the same time processes the signal supplied from a keyboard 54 according to a program stored previously in an ROM56. A print mechanism 66 stored within a print part 10 is driven by a print mechanism driver interface 60 to set characters on the print paper in a desired array. The RAM58 contains a format memory which stores the format data to the print character array such as the margin data, the tag position data, etc. and a text memory which stores the printing order of a large number of character data. Then the underline reset data is transmitter prior to the space data including the tab position data, the line feed data, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a data transmitting device, and in 4) when transmitting unlined data, if space data related to tab data or line feed data is being transmitted, the space data is unlined. The present invention relates to a data transmitting device that transmits data as unaccompanied data.

Conventional technology Data such as character data representing characters input from a keyboard, line feed data, tab data, etc. is recorded in the text I memory.1. A data transmitting device is known that can sequentially transmit the contents of its text memory to an external device. In such a data transmitting device, when transmitting data 1a recorded in its axt memory in sequence, when transmitting a group of characters with an angline attached, the beginning of the character code corresponding to those characters is Character data representing a character with an angle line is transmitted to the external device by transmitting an angle line seso I and code L to the position, and transmitting an auto angle line reset code at the end of the transmission of these character codes. However, in such conventional transmitting devices, when transmitting tab data, the area from the current data position to the next tab position is replaced with space data, and when transmitting line feed data, the origin of the next line (absolute left margin) is replaced with space data.
It was common for the entire left margin to be replaced with space data before being sent. Therefore, there was a drawback that the space data replaced in this way would cause the underground line to be lost.

Purpose of the Invention The present invention has been made against the background of the above circumstances,
The purpose of this is to transfer data with unlined lines so that when printing is performed based on the transferred data, unlined lines will not appear between spaces created by line feed operations or tab operations. The purpose is to provide a data transmission device.

In addition, a text memory is provided for appropriately storing the format 1 data, line feed data, etc. in a mixed state between single character data. ”1 Fumiko) - Kazuya is Alpha Head.

It includes not only numbers, symbols, etc., but also space data for moving the printing position. In short, character data is data related to moving the carriage, and requires changing the printing position.

The operation of the electronic data recorder constructed as described above will be explained with reference to the flowchart shown in FIG.

First, an initialization process (not shown) is executed simultaneously with the operation of the power switch 22 of the electronic typewriter, and the contents of various counts, registers, etc. are cleared. Then, according to the operation of the character key 26, etc., character data corresponding to the desired character is stored in the next text I memory, and format data such as line feed data and tab position data are changed to the appropriate character register 1a. , the characters are arranged. Even if there is no such input operation, the text memory is backed up by the data storage system even when the power switch 22 is not turned on, so the previously input data may be retained. Then, prior to transferring the contents of the text memory, the mode switching key 45 is switched to the terminal mode side, and the code key 30 is switched to the terminal mode side.
and continue key 46 are operated at the same time, 0N-
It is set to LINE state. In addition, since the stop key 47 and the code key 30 are made by the same DFm, 0N-L
IN IF, the condition can be cleared.

Next, step S1 is executed, and it is determined whether a transfer operation has been performed. That is, it is determined 21' whether or not the text key, in other words, the coat' key 30 and the plus key 44 have been operated simultaneously to issue a transfer start command. If the transfer start command is not issued, other processing is executed, but if the transfer start command is issued, steps 82 and subsequent steps are executed. Other processing is omitted because it is not necessary for the explanation of the present invention. data transfer(
When the transmission (transmission) is started, 1. One piece of data is read from the beginning of the data that has been read out, and the read data is transferred to step S3. S4, S5. S
6, it is determined whether the data is Angline set data (Cat'), Angline reset data (Code), Space data (Code), Tab position data (TAB code), or Line feed data (CR flow). .

6 years old if the read data is character data, -
Since it is not any of the data described in , step S7 is executed, that one character data is sent to the external device, and step S8 is executed to check whether the text is finished, that is, it is recorded in the text memory (, E ) is checked to see if all the data has been transmitted. That is, the steps from step 32 onward are repeatedly executed until the text is terminated at step S8, and the character data of +11i1 in the text memory is continuously transmitted one by one. Here, for a character group with an underline, underline set data is stored immediately before the character code corresponding to the character group, and underline reset data is stored immediately after the character group. This distinguishes it from those that do not involve Angrain. Therefore, when transferring such data, underline seso 1- data is read out in step S2 prior to transmitting the character ko 1-' corresponding to the character with an underline. In such a case, in step S3, the read data is determined to be underline cell 1 data, so steps S9 and SIO are executed as an underline separator 1 data.
The O1-Angline flag, which is a storage means for storing the state in the A1. and auto underline,
1 data is sent to an external device. Then, in the subsequent cycles, character data corresponding to characters with anglines are sequentially transmitted in the same manner as described above, and angline set data stored immediately after the character data group is transmitted in step S2.
When the data is read out in step S4, it is folded with the unline reset 1-data, so auto unline reset S12 is executed, the auto unline flag is cleared, and the O1 to underline reset l- data are read out. Data is sent to an external device. As a result, the external device also stores the data in the transmission order, and the angry line set data and the angry line set data are stored immediately before and after the character data group corresponding to the character group with an angry line, respectively.

If the data read in step S2 is space data for opening spaces between characters,
In step s5, is the read data space data? P month will be prayed, then step S
13 is executed, and it is determined whether or not the auto unline flag is set. If it has been sent, step S171 is executed and underline data is transmitted in place of the space data, but if it has not been sent, step S15 is executed.
Space data is sent as is. Enter that underlined data or one character's worth of space! Is Umono.

If the data read in step S2 is tab position data or line feed data, it is determined in step S6 that it is tab position data or line feed data, and step S16 is executed.

In step SI6, the number of spaces is cented, but if it is tab position data, the next tab position is determined based on the digit position for specifying the tab position represented by the signal stored together with the tab position data. The number of spaces up to (the number of blank feeds) is calculated and set in a predetermined register. If the data is line feed data, the number of spaces from the origin (absolute left margin) to the left margin (I, M) is found and set in a predetermined register. The number of spaces is also recorded together with the line feed data (determined based on the Q-valued signal -υ. Then, in step S
I7 is executed and whether it is line feed data or not is '111
1 fold, and if it is not line feed data, the step 88 is performed.
The following is repeatedly executed, but if it is line feed data, step SI8 is first executed to send the line feed data to the external device, and then step 319 is executed to reset the number of spaces set in step SI6 to zero. Whether or not: 111 is rejected. If it is zero, step S8 is repeatedly executed, but if it is not zero, the following steps S20 to S25 are repeated until the set number of spaces becomes zero.

That is, in steps S20 and S2L, the unline reset data is sent to the external device, and subsequently one space data is sent, and then step 322 is executed, and 1 is subtracted from the number of spaces that have been cleared. It will be done.

Next, it is determined whether the subtracted result has become zero in step s23, and if it has not become zero, steps S20 to S23 are repeatedly executed, but if it has become zero, step s24 is executed, It is determined whether the auto unline flag is set. If it has not been set, step S19 is directly executed because unlined data is not being transmitted, but if it has been set, step S19 is executed directly.
Step 319 is executed again after the auto-angle set data is sent to the external device.

Therefore, step S6,320. S24. S25 forms an unline control means that clears the underline sesoto state of the transmitted data when the tab position data or line feed data is read from the text memory during auto unline set data, and during the subsequent transmission of space data. -ing

As described above, according to the present embodiment, in the auto angle line set data, when space data related to tab position data or 4-line feed data is transmitted, the angle line set data is transmitted prior to transmitting the space data, Also, after the space data transmission is completed, the
- Angline set data is sent. Therefore, when printing or displaying is performed on the external device based on such transmitted data, the auto-angline flag of the external device is reset by the set data. , and is set to the auto-angline reset state by the auto-angline set data, and is configured so that an Angline is attached to characters printed or displayed according to the Angline flag from O1 to Angline flag, so tab operations or 6
This means that an unlined line will not be inserted into the space corresponding to the space created by the line break operation.

The above-mentioned embodiment is merely one embodiment of the present invention, and various modifications may be made to the present invention without departing from the spirit thereof.
