The seat reservation system, MARS 105, for the Japanese National Railways is one of the largest on-time systems in Japan, and meets the demand for extremely high system availability. The terminal equipment consists of a terminal controller (with operational board) and a ticket printer. Integrated circuits (IC) are used for the controller to achieve compact construction, and the controller and operational board are combined into a desk. The operational board has three types of input devices-ten key (numeric keyboard switch), full key, and page-designed to input request information such as the date of boarding and the name of train. It also has lamps to display input and answer message. The controller consists of IC logic circuits (and their power supply) for input control in the reading, storing, displaying, and editing of input information; control of transmission to and reception from the central unit; and of output control in answer messages checking and printing. The ticket printer is designed to print out answer messages obtained from the central unit. The ticket printer is composed of a 128-character impact printer (printing speed: 20 character/second) and a printing controller.
