<p>PURPOSE:To obtain the excellent hand of use and to shorten the time for a treatment by setting the rising and turning speed of at least a back rest part higher than an ordinary turning speed. CONSTITUTION:The rising and turning speed of the back rest part is set at a slightly high speed and the laying down and turning speed is set at an ordinary speed by a speed setter 43. The slow start speed and slow down speed to lower the speed in the initial or final period of the rising and turning speed and laying down and turning speed of the back rest part are set by a slow start and slow down setter 45. The respective set speeds are inputted from a speed memory section 44 and a slow start and slow down memory section 46 simultaneously when the actually detected speed signal is inputted from a speed detector 41 of a speed control section 42 of this controller system and, therefore, the rising of the back rest part is started slow and after the back rest part rises fast, the rising slows down. The excellent hand of use well suited to the form of the actual treatment is, therefore, obtd.</p> |
