Claims

[Scope of utility model registration request]

Inside the case body of the demagnetizer, there is a degaussing signal generation circuit that generates alternating electric sand, a microswitch that controls the drive of the degaussing signal generation circuit, and a degaussing head insertion window provided in the case body. A degaussing head that faces the front side and is held retractably inside the case body, and a middle part of the degaussing head is brought into contact with the rear end of the degaussing head to press the degaussing head toward the insertion window, and both ends of the degaussing head are held. In the configuration, the microswitch is provided with an elongated spring material and an actuating piece of the microswitch driven by the spring material that protrudes and deforms as the degaussing head retreats, on the left and right of a contact point of the degaussing head on the spring material. , a degaussing device characterized in that an auxiliary spring member that acts to push back the spring material is provided on the side opposite to where the actuating piece is located so that the force pushing back the demagnetizing head is approximately equal on the left and right sides. vessel.
