Abstract: Disclosed is an improved fire alarm system for an information providing system having a plurality of terminal devices for providing information to a plurality of operators, respectively. The fire alarm system is provided with a fire detecting sensors. If a fire is detected, a predetermined signal is transmitted to a controller. The controller controls each of the plurality of terminal devices to indicate an alarm information to the operator when the predetermined signal is received.

Abstract: The invention provides an improved music-generating system for efficiently supplying newly available music data to a plurality of music-generating terminal units. The music-generating system includes a host unit and a plurality of music-generating terminal units, and works basically as follows. The host unit transmits music data input through input circuitry to each of the plurality of music-generating terminal units via transmitting circuitry. The music-generating terminal unit receives music data transmitted from the host unit by receiving circuitry. Writing circuitry transmits and writes the music data onto memory. When selection signals are sent from an external device to the music-generating terminal unit, reproducing circuitry reads out specified music data from the memory according to the selection signals and reproduces music corresponding to the music data.

Abstract: A prepaid card processing device for processing a prepaid card has a memory for storing information relating to an account, e.g., of money, and a printing portion on which the information is recorded. A prepaid card processing device has a reading portion for reading the information stored in the card memory; an input portion for inputting a charge amount of money for a transaction; a defrayal information processing portion for calculating the balance amount based on the charge amount inputted by the input portion and for preparing the defrayal information relating to the balance amount and the charge amount; a printing portion for printing defrayal information on the card; and a decision control portion for deciding whether or not the defrayal information is to be printed on the card by the printing portion. When the decision control portion decides that printing need not be performed, no printing on the card occurs. Thereby, the printing space on the card can be effectively utilized.
