2 shows a bed 1 provided with a floor undulating mechanism having a rising angle adjusting means. The bed 1 includes an operation switch Sw that supplies an operation command signal to an electric floor undulating mechanism (not shown).
_It has a hand switch 3 (wired system) on which _{1 to} Sw ₆ is mounted and which can be operated on the floor 2, and a motor (described later) for operating the floor undulating mechanism,
The hand switch 3 is provided with an operation switch 4 for setting a floor rising angle and a display means 5 (such as a liquid crystal display means). The operation switches Sw _{1 to} Sw ₆ are used, for example, to give operation commands for raising / lowering the back, raising / lowering the knee, and raising / lowering the entire floor by the floor raising / lowering mechanism, respectively. The floor wake-up angle setting operation switch 4 is used for setting and inputting the wake-up angle of the floor 2. In the bed 1 configured as described above, the floor undulating mechanism is the operation switch S in the hand switch 3.
w _{1 to} Sw ₆ , an operation signal from the floor rising angle setting operation switch 4 is transmitted via a signal cable 6 to a controller (described later) mounted on a control box (not shown) provided on a frame below the floor 2. By introducing and controlling the motor drive by this controller,
The undulating operation of the floor 2 is performed. Further, the controller takes in a signal corresponding to the rotation amount from a rotation amount detection means (not shown) provided in the motor.

Next, a description will be given of a rising angle adjusting means of the floor raising / lowering mechanism. That is, as shown in FIG. 2, a controller 7 constituted by a well-known control circuit is mounted on a control box provided on the frame below the floor 2 described above. Such controller 7, with the hand switch 3, the signal according to the wake-up angle setting of the floor portion 2 by the floor portion wakeup angle setting operation switch 4 via the signal cable 6 Sa, operation switches Sw ₁ to SW ₆ A display signal Sc is provided to the display means 5 of the hand switch 3 based on a key input signal Sb relating to an operation command of the floor unit 2 and a signal Sa relating to the setting of the rising angle.

That is, the controller 7 uses a well-known setting circuit each time the floor-rise angle setting operation switch 4 is pressed, for example, 50 ° → 55 ° → 60 ° → 65.
° → 70 ° → 75 ° → 50 °, etc., and the wake-up angle is set stepwise, and the display means 5 displays the display signal Sc.
