发明名称 Emitted-radio-wave shield and image forming apparatus using same
摘要 An emitted-radio-wave shield capable of preventing the leakage of emitted radio waves from a circuit board includes a shield box, which houses the circuit board, and a shield plate that is easy to attach and remove in order to access the circuit board. A shield member, which is disposed at a joint between the shield box and the shield plate and is electrically connected with the shield box, shields emitted radio waves from the circuit board in a state in which the shield plate is secured to the shield box. The shield plate is formed to have a plurality of protrusions, which project toward the shield member, at a part thereof that contacts the shield member.
