Abstract

PURPOSE:To control a remote side receiver to a state suited for reception by transmitting a line feed signal to a device of the remote side prior to transmission of the text data. CONSTITUTION:The data fed through a keyboard are stored to a text memory and the contents of the text memory are transmitted to an external device by a data transmitter. For such a data transmitter, a line feed code is transmitted prior to transmission of the date. In other words, a text key is turned on and the presence of a text is decided at a block 11. Thus a C/R code is transmitted through a block 13. A device of the remote side receives the C/R code and performs a carriage return action to secure a state suited to reception of the text. Then the received data are printed with line feed.

Various control keys are provided for changing or canceling settings such as C0NT, text transmission key TXT, stop key ST, carriage turn to left margin (C/R), left and right margins, tabs (TAB), etc. . The group of control keys also includes a bank space key, a shift key, a paper feed key, a paper return key, a repeat key, a cursor key, a code key, a delete key, an insert key, and the like. 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 transmission mode as a data transmission device according to the present invention. Online sending key CON
T puts the communication with the receiving device on-line, and the text transmission key TXT is a key for starting the transmission of data stored in the text memory of this electronic type-like.

The stop key ST is a key for stopping various operations. The delete key DI is used to delete a character or line, and the insert key IN is used to insert a character or line, respectively, in order to edit the text stored in the text memory. In addition, since this electronic typewriter is also equipped with an arithmetic function, it also has a group of various keys such as 10-x÷- and clear, as well as a type-arithmetic switching key.

In addition, the keyboard section K of this electronic typewriter has
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 cost.

The printer part P has a platen I inside the upper cover C)
Carriage Ca moving along L and guide bar CB
will be placed. Although various types of printing heads PH carried by the carriage can be used, thermal heads Th and 1I are advantageous in terms of power consumption, small size and light weight. The thermal heads Th and Il are arranged with a large number of heating elements that selectively generate heat according to input.
Printing is performed in dot matrix format on plain paper via thermal paper or thermal ribbon placed on a platen.

The electronic typewriter according to this embodiment is driven by a battery power supply built into the printer part P, and has a power switch SW installed at an appropriate position on the main body case.
