<p>PURPOSE:To eliminate the generation of physical irritancies except heat and air during operations with a sharp stopping property of rising or falling of the heat and air by arranging a position sensor for detecting the present position of a shutter and an air/heat control means for controlling the opening or closing of air and heat sources to dispense with a visible light cutting filter. CONSTITUTION:Two position sensors 6 and 6a are arranged at a position of an equal angle of 90 deg., respectively with respect to the center of rotation of a shutter 5. It is so set that, when one sensor section is covered with the shutter 5, this sensor section alone is turned ON and when both the sensor sections are covered with the shutter 5, both the sensor sections are turned ON, which always allows the detection of the present position of the shutter 5. In this autonomic training apparatus, a heat source 3 employs a far infrared ceramic heater. The heat source 3 not only eliminates a visible light cutting filter but also allows improving of maintaining performance with a longer life while it provides a soft touching of heat with a longer radiation wavelength. The opening or closing of the air and heat sources 2 and 3 with one sheet of shutter 5 achieves a quick and sharp rising in the switching of air and heat, thereby eliminating possible hissing sound without turbulence otherwise caused by the blowing of air.</p> |
