Abstract: A fan box is provided with, in addition to an intake port in the front face, a second intake port at a wall surface position upstream of a fan. An Input/output unit disposed above or below the fan box comprises an exhaust notch that is aligned with the second intake port of the fan box, as well as an intake notch that is provided further to the rear than the exhaust notch. The intake notch is in communication with an air duct that opens in the front face of the processor and that leads to a unit box. The fan discharges through an exhaust port cooling wind that has flowed into the first intake port via an operation unit, as well as cooling wind that has flowed into the second intake port via the Input/output unit.

Abstract: A stretcher 1 comprises a bed 21 on which a sick or injured person will be laid, legs 22 foldably provided on the bed 21, casters 23 provided at the legs 22, respectively, a tank 10 for storing high-pressure gas, pneumatic cylinders 8 and 9, and intake switches 11 and 13. When the intake switches 11 and 13 are turned ON, high-pressure gas is introduced from the tank 10 into the pneumatic cylinders 8 and 9 so that piston rods 28 are retracted. Thus, the legs 22 are given forces toward deployment so that the bed 21 is given an ascending force.
