PURPOSE:To enhance the service by transmitting the objective floor by key operation with a portable card by means of electromagnetic waves together with the own specific code, and at this time, receiving signal in the neighborhood of each place for getting on, and selecting and allocating the optimum response unit using a group managing means. CONSTITUTION:Through key entry the objective floor is commanded by the use of a portable card 1 possessed by a user, and now it is transmitted via electromagnetic waves together with his own specific code to be received by a receiving antenna 21 of a sensor panel 20 provided at the place for getting on the floor concerned, and this signal is forwarded to an elevator control part 30 via a demodulator circuit 22. The group managing means of this elevator control part 30 selects and allocates the optimum response unit for the floor to which the received command is applicable, and the information is sent to the portable card 1 via a converter circuit 23 and a transmitting antenna 24. Thereby the portable card 1 displays on the display when identical to the own card. Thus service enhancement is obtained. |
