Claims

[Scope of Claim for Utility Model Registration] (1) In a rotary seat that rotates the seat using power to change the direction of the seat and is provided with an armrest, 1. A rotary seat characterized in that a pressure sensor capable of detecting pressure applied to the arm rest is disposed in order to control the rotation of the arm rest. (2) In a rotary seat that rotates the seat using power to change the direction of the seat and is equipped with an armrest, a pressure sensor disposed on the arm rest of the armrest, and the pressure sensor. an A/D converter that converts the pressure value detected by the A/D converter into a digital value; a comparison circuit that compares the digital value from the A/D converter with a reference value; A rotary seat characterized by comprising a control unit that stops rotation of the seat when it is determined that no arm is placed on the seat.
