    摘要: A motor-driven time switch is disclosed which comprises a time switch mechanism having a time setting cam, leaf spring contacts forming a switching unit operated by the time setting cam, and terminals for connecting the leaf spring contacts to external equipment and a motor for rotating the cam. Terminal pin mounting parts are formed on the coil bobbin of the motor. The end portions of the wire forming the coil of the motor are wound on terminal pins press-fitted into the terminal pin mounting parts. The terminal pins are connected to the aforementioned terminals.

    摘要: This invention is intended for the communication between a first communication device (e.g., an IC card) and a second communication device (e.g., a card terminal) by preventing the faking of the IC card or card terminal, for example, thereby allowing correct information exchange between them. The invention provides the IC card with a first encryption means and the card terminal with a second encryption means. In consequence, communication signals in both directions are encrypted, and random numbers and the algorism of functional computation are prevented from being analyzed. As a result, manufacturing of fake devices can be prevented and correct information exchange can be performed.
