Abstract

PURPOSE:To attain data transmission with no waste with an electronic typewriter having an external transmission function, by transmitting only the next input character in case the synthesizing is impossible for said next input character which is fed after the push of a dead key. CONSTITUTION:When a dead key is pushed, the corresponding data is stored to a dead key register and at the same time displayed at a display part. Then the adaptability is decided between the dead key and the next character key after this key is fed. When the synthesization is possible between the dead key data stored in the dead key register and the data of the next input character key according to the result of the above-mentioned decision, a combined character code is transmitted. If the synthesization is impossible, the dead key data is invalidated. Then only the next input data is transmitted.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an online data transmitting device for transmitting data input from a keyboard to an external device in an online mode, and in particular, an online data transmitting device built in an electronic quiwriter and connected to a similar device or a suitable computer. This relates to an online data transmission device for transmitting data entered from a keyboard to an external device.The pre-order is not only capable of printing directly when keys are pressed, but also capable of storing the desired capacity. Many have built-in devices that enable printing after a predetermined period of time or after ji, iJ at any time. Therefore, such an electronic quiwriter uses a read-only memory (hereinafter referred to as ROM) that includes a program memory in which the 7Ji standard program is written and a pattern memory that stores patterns such as characters and symbols.
) and a rewritable memory (hereinafter referred to as RAM).A variety of functions are achieved by the built-in storage device and the central processing unit CPU K for controlling it.

One such feature is the ability to send data online to similar devices or other external devices.

This conventional heel online data transmission device has difficulty in processing and transmitting data associated with pressing the Punto key. Here, a dead key is a key that does not function as a single character or symbol by itself, such as the German umlaut pa...'' or the French accent silicon flex ゛^'', and therefore does not involve carriage movement on part of the printer. This is a general term for a group of keys for inputting irregular codes. When such a dead key is pressed, the subsequent key does not necessarily match the dead key. There are many cases in which non-conforming characters are formed due to an error. In other words, there are cases where a dead key is pressed twice or a character key such as B or C is pressed after an umlaut. If data were to be sent to the outside each time the data was changed, a cancellation operation would be required afterwards, resulting in wasteful data transmission.

In addition, if the put key data is sent immediately, there is a possibility that the key will be pressed twice, leading to operational concerns.

The present invention provides a data transmitting device for transmitting data input from a keyboard to an external device, which can reasonably process and transmit input data using dead keys. purpose.

This purpose is to provide an online data transmitting device according to the claims, namely, a dead key register that stores dead key data when a dead key is pressed, and data from the next input key stored in the dead key register. When it is possible to synthesize with dead key data, (II
a code of a combination character of the Punto key data and the next character key data, and when it is impossible to synthesize the code,
This is accomplished by an online data transmission device comprising:

The invention will now be described in detail with reference to the accompanying drawings, which illustrate embodiments of the invention.

FIG. 1 is a perspective view schematically showing an electronic typewriter incorporating an online data transmission device according to the present invention;
It is roughly divided into a keyboard part K and a printer part P.

The keyboard part KVc in the figure includes a group of keys such as the required number of character keys, numeric keys, symbol keys, etc., as well as a space bar SP1 mode setting key Mo, as is well known in ordinary typewriters.
, Online sending key GONT, Text sending key T
Various control keys are provided for changing or canceling settings such as XT, stop key ST, carriage return C/R, left and right margins LM, FM, and tab TAB.

These control keys also include the bank space key,
Line feed key, shift key, paper feed key, paper return key, repeat key, cursor key, code key, delete key D
L, insert key IN, etc. are included. The mode setting key Mo is a key for selecting and setting the operating mode of the electronic typewriter, and is, for example, a normal print mode and a transmission key as an online data receiving device according to the present invention.

A stop key ST is a key for stopping various operations.

The delete key DL is a key for deleting a character or line, and the insert key IN is a key for inserting a character or line.

In addition, this electronic type-like is also equipped with arithmetic functions, so you can use the 10-×
It also has various key groups such as ÷= and clear.

In addition, the keyboard section K of this electronic typewriter has
A display section for displaying the number of digits is provided to display the contents of the characters, symbols, etc. that are entered on the key.

This display part can be used with a suitable display manufacturer, but from the point of view of power consumption and cost, it is difficult to use a liquid crystal display L (
J is advantageous.

will be placed. Print head P carried by this carriage
Although various types of heads can be used for H, thermal heads Th and H are advantageous in terms of power consumption and small size and light weight. A thermal head has a large array of heating elements that selectively generate heat according to input, and prints in dot matrix format on plain paper via thermal paper or thermal ribbon placed on a platen. be.

It should be noted that the electronic typewriter according to this embodiment is powered by a power source built into the printer part P.
It is turned off by a power switch SW installed at an appropriate position on the main body case.

Needless to say, it can also be used with commercial power by using an AC adapter.

FIG. 2 is a block diagram of an electronic typewriter incorporating an online data transmission device according to the present invention. This valley section includes the keyboard section K, display section and printer section P shown in the visible part of Figure 1, as well as the central processing unit CPU, ROM, RAM, etc. built into the main body case.

Note that the keyboard section has one display section and the printer section P has a keyboard driver KD and a display section controller D as necessary auxiliary circuits.

and a printer driver interface PI. Furthermore, this electronic typewriter is equipped with an external interface dryer/resino (-rRy7) so that information can be exchanged with the outside. It transmits information to other external devices such as computers via suitable interfaces, including similar devices connected to the head and lid, and drives the printer part P according to the information received from these devices. can do.

In the online data transmission device according to the present invention, when a dead key is pressed manually, this data is stored in the dead key register, displayed on the display section D (Fig. 1), and then pressed (1). The CPU waits for the input of the next character key to determine whether or not the two characters are compatible.

As determined by the CPU, if the dead key data stored in the dead key register and the data from the next consecutive character data can be synthesized, the combination character code of the dead key data and the next character data is transmitted, and the register is Clear. If it is determined that synthesis is not possible, the dead key data is invalidated and only the next input data is transmitted.

It will be obvious to those skilled in the art that each of the elements forming each block in FIG. 2 can be constructed using well-known elements or devices, such as LSI circuit elements, printer mechanisms, and the like.

FIG. 5 is a flowchart showing the operating state of the online data transmission device according to the present invention. Following the start, a kill scan is performed in block 1o to detect whether any key on the keyboard is pressed. It is done.

As a result of this key scan, it is determined in block 11 whether any key is ON VC or not.

If none of the keys are turned ON, key scanning and determination are repeated. If it is determined in block 11 that any key is in the ONK state, then it is determined in block 12 whether the key in the ON state is the Punto key or any other key.

If the judgment in block 12 is YES, this means that the key is dead, so the data transmitting device will not send this data as is (1).
, stores predetermined data in the dead key register as shown in block 13. This state and the content of the dead key are displayed on the display section D (FIG. 1), and the above operations are repeated until the next character key is pressed.

On the other hand, if the judgment in block 12 is 1-, it means that a key other than the dead key was pressed, so in block 15, it is stored in the dead key register corresponding to block 16 described in j4'J. It is determined whether the specified content exists or not. If YES as to whether there is a dead key register, it is determined in block 16 whether the currently pressed key is a character code or a function code other than that.

If the determination in block 16 is YES, -j-, that is, the key input is a character code, it is determined in block 17 whether or not it is possible to combine the character with the previous dead key. If this judgment is YES, block 1
A combination character code of a dead key and a character, such as 8, is cented.

On the other hand, if the judgment in block 17 is NO, it means that it is impossible to combine the preceding dead key and the following character, so the contents of the Punto key are invalidated, and as in block 19, the next character code is be done.

If the determination in block 16 is NO, it means that the pressed key is a function key that is neither a dead key nor a character key, so the contents of the dead key register are erased as in block 20, and then as in block 21. Set the function code corresponding to the pressed key to .

In response to any of the states in blocks 18, 19 and 21, the Punto key is displayed as shown in block 22 (block 14).
(displayed in block 26) and at the same time data transmission is performed as in block 26. The content transmitted here is either (II character code for the combination of dead key and subsequent character, (lIJ subsequent character code, (IIIl function code), or (II) corresponding to block 18.
is a case where the dead key and the following character can be synthesized, and the above (Ill) is a case where they cannot be synthesized. In the case of the above (rule), the data corresponding to the dead key is deleted and the required data will be transmitted only.

If the judgment in block 15 is No, it indicates that the currently pressed key is not a dead key, and the fact that a previous dead key was pressed is not stored, that is, the pressed state of a key unrelated to the Punto key. All blocks 16 to 22 are skipped and data transmission in block 23 is immediately executed.

After this data transmission is performed, the process moves to key scanning in block 10, and the above-described operations are performed until an input is performed by pressing the next key.

According to the data transmitting device according to the present invention, when only a dead key is pressed to an external device that is online, the data is simply displayed on the transmitting device and the data is not sent.
The data of the combination of the dead key and the character or the data of the next character whose combination with the next character has been determined in the transmitting device is transmitted. As a result, the operator can select and press the next character key while checking the display of the dead key. Furthermore, when transmitting data, it is determined in advance whether or not it can be combined with the next character before transmitting, so there is waste in data transmission, for example, a situation where a dead key code is sent immediately and then canceled by the next character. This makes it possible to eliminate errors and reduce operational errors as much as possible.
