Claims

[Claims for Utility Model Registration] A guide ring that draws an arc upwardly is fixed to the base, an arm cuff is wound around the inside of the guide ring in a substantially cylindrical shape, and the area near the inner tip of the arm cuff is attached to the base. The outer end of the arm cuff is fixed to a slider that slides along the guide ring, and the arm cuff is fixed to a base near the inner tip of the arm cuff and is arranged along the outside of the arm cuff. A rope and an unwinding rope fixed to the slider are wound around a rope pulley, and a winding clutch that transmits the driving force of the motor to the rope pulley, a rewinding clutch, and a wrist cuff loosening when pressurized. In an automatic blood pressure monitor in which a locking clutch for locking is disposed on the same axis as the rope pulley, a pinion gear attached to the rotating shaft of the rope pulley, a cam gear meshing with the pinion gear, and two recesses rotating coaxially with the cam gear are provided. A limit switch including a formed cam, a contact piece that comes into contact with the recess and is displaced, and a control circuit that performs forward/reverse rotation and stopping of the motor based on a signal from the limit switch and a load signal from the motor. A wrist cuff malfunction prevention mechanism for an automatic blood pressure monitor, which is characterized by:
