PURPOSE:To avoid undesired data from being sent when misoperation takes place or confirming operation is executed by sending a code data and that for a shift key bit just before to a code key operated just after the operation without immediate sending of the corresponding data at the operation of a specific shift key. CONSTITUTION:A means storing the result of shift key operation in a prescribed area B1 of the 1st memory 23-1, a means discriminating the operation of the shift key and code key and sending a code and a means sending a code data when the code key is operated sequentially area stored as programs. In operating a keyboard 1, a keyboard control circuit 25 is controlled by a microprocessor 1 to obtain a code data. In operating the specific shift key, a bit representing it is stored in the 1st memory 23-1. When the code key is operated further, the bit to the code key is sent together with the code key data and sent to a prescribed device through a transmission line 4 via a line controller 24, the 1st MODEM3.
