Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data transmitting and receiving device that transmits and receives data to and from an external device.

The electronic typewriter, which is the main body of the data transmitting/receiving device according to the present invention, is not only capable of printing directly when keys are pressed, but also has a built-in storage device of a desired capacity so that printing can be performed after a predetermined time or any arbitrary time. There are many things that I did. Therefore, such electronic typewriters include a read-only memory (hereinafter referred to as ROM) that includes a program memory in which a predetermined program is written and a pattern memory that stores patterns such as character symbols, and a rewritable memory (hereinafter referred to as ROM). (referred to as RAM) and a central processing unit C for controlling these devices.
Various functions are exhibited by the PU.

One such function is to transmit the contents stored in the text memory in the RAM to a similar device or other external device, or to receive data from the other device. In conventional data transmitting/receiving devices of this type, if there is a shortage of printing paper and it is necessary to perform paper feeding or paper return operations while transmitting or receiving data, that is, while online, these operations are performed after going offline. had to be done. This was extremely inefficient and inconvenient because the lines that had been formed up until then were eliminated. This is uneconomical not only when an operator is always on standby near the other party's device 1, but also when data is transmitted and received automatically.

The present invention provides a data transmitting/receiving device that can insert a paper feed signal as necessary even during so-called online time during data transmission or reception, and thereby perform paper feeding or paper exchange. With the goal.

This object is achieved by a data transmitting/receiving device having the configuration described in the claims, that is, when a paper feed signal is inserted during data transmission or data reception, paper feed data is sent to a predetermined position of the data being transmitted and received. This is accomplished by a data transmitting/receiving device comprising means for inserting.

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 type-like device incorporating a data transmitting/receiving device according to the present invention, which is roughly divided into a keyboard portion K and a printer portion P.

The keyboard portion K in the figure includes a required number of various key groups such as character keys, numeric keys, and symbol keys, as well as a space bar SB, as is well known in ordinary typewriters, as well as a mode setting key M o , an online key C0NT, Text transmission key TXT, stop key ST, carriage return to left margin (C/R), left and right margins and tabs (
Various control keys are provided for changing or canceling settings such as TAB). These control keys include a hack space key, a shift key, a paper feed key LF, and a paper return key B.
Includes LF, repeat key, cursor key, code key, delete key, insert key, etc. The mode setting key Mo is a key for selecting and setting the operating mode of the electronic typewriter, and can be used to switch between, for example, a normal typewriter mode and a data transmitting/receiving mode as a data transmitting/receiving device according to the present invention. Online key〇〇N
T puts the communication on-line with the receiving device, and the text transmission key TXT is a key for starting the transmission of data stored in the text memory of this electronic typewriter.

The stop key ST is a key for stopping various operations, and can, for example, switch an online state to an offline state.

The paper feed key LF is a key to feed a portion of paper in the printer in the forward direction, and the paper return key BLF is a key to feed the paper in the reverse direction. In addition, since this electronic typewriter also has a calculation function, it also has a group of various keys such as +-×÷- and clear, as well as a type-calculation switch key.

In addition, the keyboard part K of this electronic type-like,
A display section with the required number of digits is provided to display the contents of characters, symbols, etc. that have been pressed. Although any suitable display device can be used for this display section, a liquid crystal display device LCD is advantageous in terms of power consumption and low cost.

In the printer part P, a carriage Ca that moves along a platen PL and a guide bar CB is disposed within an upper cover C. Although various types of print heads PH carried by the carriage Ca can be used, the thermal head Th is more advantageous in terms of power consumption, small size, and light weight. The thermal heads Th and II are arranged with a large number of heating elements that selectively generate heat according to the input, and are arranged in a donmatrix format on thermal paper arranged on a platen or on plain paper via a thermal ribbon. It is printed.

The electronic typewriter according to this embodiment is driven by a battery power source built into the printer part P, and is turned off by a power switch SW mounted at an appropriate position in 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 a data transmitting/receiving device according to the present invention.

These parts are the keyboard part K shown in the visible part of FIG.
It includes a display section, a printer section P, a central processing unit CPU, ROM, RAM, etc. built in the main body case. The keyboard section K, the display section, and the printer section P are each equipped with a keyboard driver KD, a display section controller DC, and a printer interface PI as necessary auxiliary circuits.

Furthermore, this electronic typewriter is equipped with an external interface driver/receiver-IR so that information can be exchanged with the outside. Therefore, for example, the first
As shown in the figure, information is sent to other computers etc. via appropriate interfaces, including similar devices connected to the connector CN provided on the side of the device, and the printer part P is operated according to information received from these devices. Can be driven.

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 and other circuit elements, printer mechanisms, and the like.

The data transmitting/receiving device according to the present invention can store data in the text memory in the RAM by operating the keyboard. This is carried out by the normal typewriter mode of the electronic quiwriter incorporating the device. The data stored in this way can be transmitted to a similar device as well as a personal computer or other external device via an appropriate line, and data can be received from the external device. In this case, in the data transmitting/receiving device according to the present invention, when it becomes necessary to feed or return paper, it is possible to operate the paper feed key LF or the paper return key BLF while maintaining online operation,
The device thereby performs the required operation. During this time, necessary paper feeding or paper return operations or paper replacement are performed. Of course, operations and actions corresponding to these are possible when offline.

When paper feeding or paper exchange is completed and the printer is ready for printing, data transmission is performed immediately because the device is online.

Therefore, when receiving data from, for example, a personal combiator using the data transmitting and receiving device according to the present invention, if you wish to exchange the reception form at the end of the program on the computer side, you can transmit and receive data while remaining online as described above. After a temporary interruption, during which paper is replaced on the receiving side, data transmission and reception of a new program can be resumed immediately.

FIG. 3 shows a flowchart showing the operation of essential parts of the data transmitting/receiving device according to the present invention. Key input is performed as in block 10 during data transmission and reception. Next, in block 11, the operation key is the paper feed key L.
It is determined whether the key is F or the paper return key BLF.

If this judgment is YES, the LF
Alternatively, a paper feed or return operation is performed according to BLF processing.

If the determination in block 11 is NO, in block 13,
It is determined whether the device was online. YE
In the case of S, online key manual processing is performed in block 14. For example, when the stop key ST is pressed, data transmission is temporarily interrupted, and then the next process such as block 15 is performed.

If the determination in block 13 is NO, the device is off-line, and key manual processing at offline time is performed as shown in block 16. This is a free operation such as paper feeding operation or mode setting, and then the next process is performed as in block 15.

As described above, according to the data transmitting/receiving device according to the present invention, even if data is being transmitted and received online, if it becomes necessary to operate the paper feed key LF or the paper return key BLF, you can freely operate the paper feed key LF or the paper return key BLF. Operation becomes possible. Therefore, it is possible to send and receive data without disconnecting the online line each time, and great benefits can be obtained in terms of time and effort. When offline, it is of course possible to feed paper, return paper, or replace paper by operating the printer.
