Abstract: In a nameplate apparatus incorporating a communication unit therein, the communication unit is formed in a thin film shape and transmits a coded code specific to the nameplate apparatus. On a front surface of this thin-film shaped communication unit, a display plate is mounted so as to display information such as a name, whereas on a rear surface of the communication unit, a holding member is provided so as to detachably secure the communication unit to a user's clothing or the like. In a data processing apparatus, after the coded code transmitted from the communication unit is determined to be coincident with a predetermined identification code, the data processing apparatus is brought into an operable condition.

Abstract: A data transmission system includes a data transmitter/receiver connected to an ECR and a data processor. The transmitter/receiver receives data from the ECR and transmits the reception data to the data processor, and includes a storage means for storing the reception data as transmitted data after the reception data is transmitted. The data processor is connected to the transmitter/receiver and continuously processes data from buffer memories for storing data sent from the transmitter/receiver. The transmitter/receiver sends the transmitted data again after a power supply for the data processor is recovered.

Abstract: A printing apparatus includes an electronic cash register body provided with a keyboard including entry keys and subtotal-closing key. An associated central processing unit includes registers for storing data to be printed and sends printing data furnished by key operation. When the subtotal-closing key is actuated, a recording sheet held in a printing section is caused to move forward a pre-determined distance after printing is completed, and a setting mark is printed on the recording sheet. The setting mark allows the recording sheet to be aligned with the printing section so that printing will continue from the next successive data line when the recording sheet is reinserted in the printing section.
