Claims

[Scope of utility model registration request]

A switching element that switches when a power supply bias is applied, a filter circuit that changes a filter frequency by switching the switching element, a noise reduction circuit that receives a recording signal via the filter circuit, and operation of the noise reduction circuit. a first switch that switches to an on contact and applies the power supply bias to the switching element via the on contact; a switching piece that is connected to the off contact of the first switch; and a normal tape contact and a non-normal tape contact. and a second switch that applies the power supply bias to the switching element via the off contact by switching to the normal tape contact.
