Disclosed is a means to detect LID status indicating LCD cover condition. This means enables detection of LID status using lead switch device and magnetic speaker u source of magnetic field without using separate dedicated magnet unit. (Problem to be solved) Traditional design to detect LID status is using tact switch, which is mechanical switch. to have correct status detection, detection means by tact switch requires rigid constructi tact switch device and high mechanical accuracy. As alternative means for the case where above mechanical requirements are not satisfied, these is detection device using lead switch using mechanical position detector by magnetic But, placing additional magnet may cause interference towards to media which is sensitive
