Japanese Patent JP7358181
Kind Code:
B2
Abstract:
To highly accurately detect low speed and intermittent rotation of a shaft section without a power source.SOLUTION: The rotation operation device is provided with a shaft section 12 with a base end side rotatably supported by a front wall section 3A of a housing of a commodity bending machine, a handle 13 provided to a tip end side of the shaft section 12 and rotates the shaft section 12, and a rotation detection unit 14 arranged at a base end side of the shaft section 12. The rotation detection unit 14 includes a magnetic sensor 17 having a magnetic element generating a large Barkhausen effect, and magnets 15 and 16 forming a magnetic field around the magnetic sensor 17. The magnets 15 and 16 are attached to the base end of the shaft section 12, and rotates with the shaft section 12. The magnetic sensor 17 is attached to the housing of the commodity bending machine. The magnetic sensor 17 and the magnet 15 are arranged to face each other via a gap.SELECTED DRAWING: Figure 3
