PURPOSE: An interval controller for an autotrack is provided to lengthen the life span of the autotrack by preventing the damage on the autotrack, to easily maintain the autotrack, and to improve economical efficiency by reducing the cost of management. CONSTITUTION: Plural interval control signal lines(23) are installed along the traveling direction around a pair of power supply lines(21) and divided at a specific interval. A main control unit(31) applying a stop signal and a travel signal to the interval control signal lines is connected to an interval control unit(29). The interval control unit has many relays sensing the control signal of the interval control signal lines and applying the control signal of the interval control signal lines. The relays apply the traveling control signal generated from the main control unit to the interval control signal lines. Insulators(27) are installed between the interval control signal lines to discriminate the control signals of the interval control unit.
