<p>PROBLEM TO BE SOLVED: To provide a motor operating device for a Gatch bed having a small difference of speeds at rising and falling times and capable of being reduced in size and weight. SOLUTION: The motor operating device for the Gatch bed rises and falls the front part of the bed capable of rising and falling at one part or a plurality of parts (not shown) of a bed floor by the driving force of a motor M1 by a DC voltage. The device comprises switching circuits 6, 200a, 220 for switching the voltage to a first voltage when the part is fallen and to a second voltage higher than the first voltage when the part is risen to decelerate the difference of the falling and rising speeds of the part.</p> |
