Claims (7)

A bed with a back bottom;
A pivot mechanism that pivotably holds the back bottom around a pivot shaft that is positioned above the bed and extends in the left-right direction, and a support frame that supports the bed;
The rotating mechanism includes: a movable member connected to the back bottom; and a fixed member connected to the movable member via the rotating shaft;
The movable member or the fixed member is provided with an angle display unit that displays a rotation angle of the back bottom based on a relative positional relationship between the movable member and the fixed member around the rotation axis. A bed apparatus characterized by that. The support gantry includes a gantry body to which the back bottom is coupled via the rotation mechanism and receives the load of the bed;
The bed apparatus according to claim 1, wherein the fixing member is fixed to the gantry body. The bed apparatus according to claim 1, wherein the angle display unit is exposed to the outside in the left-right direction. Of the rotating mechanism, a portion located above the bed also serves as a restriction mechanism that restricts the movement of the mattress in the left-right direction by facing the mattress supported by the bed in the left-right direction. The bed apparatus according to any one of claims 1 to 3, characterized in that: A bed with a back bottom;
A pivot mechanism that pivotably holds the back bottom around a pivot shaft that is positioned above the bed and extends in the left-right direction, and a support frame that supports the bed;
Of the rotating mechanism, a portion located above the bed also serves as a restriction mechanism that restricts the movement of the mattress in the left-right direction by facing the mattress supported by the bed in the left-right direction. A sleeper device. The bed apparatus according to claim 4 or 5, wherein the restriction mechanism is disposed at a position equivalent to a lateral edge of the bed in a horizontal direction. The bed apparatus according to any one of claims 1 to 6, wherein the rotation mechanism is provided with a locking portion that locks a medical instrument.
