PURPOSE:To shorten the arrangement time at the time of varying kinds while removing waiting for the cooling of heater blocks by installing a plural kind of the heater blocks on the outer circumference of a rotatable block supporter and selecting a desired heater block as required. CONSTITUTION:Four flat mounting surfaces are formed on the outer circumferential surface of a block supporter 76 at regular intervals, and different heater blocks 78-81 are fitted to these mounting surfaces. When changing over kinds, a device is stopped, and the block supporter 76 is positioned at a lower section by reversely rotating a motor 72. A locating pin 86 is drawn out, the block supporter 76 is kept rotatably, a motor 83 is turned, the block supporter 76 is rotated at a fixed nagle, and a desired heater block such as one 80 is faced in front of a circuit substrate 1 and revolution is stopped. The locating pin 86 is penetrated into a pilot hole 78c at a lowermost level, a reference hole 85 and the pilot hole 78c are conformed, and the heater block 80 is adjusted at predetermined height by the motor 72, thus completing arrangement.
