Abstract
A conductive chassis plate faces a printed circuit board at a distance. One end of the conductive chassis plate is aligned with one end of the printed circuit board. One end of the conductive chassis plate is electrically connected to a ground wiring pattern provided on one end of the printed circuit board. One end of the conductive chassis plate is electrically connected to a conductive member that extends from one end of the conductive chassis plate toward the other end. As a result, in transmitting or receiving a signal with respect to external equipment attached to a connector, an influence of electrostatic discharge is reduced with a simple configuration.
Claims7
An electronic apparatus, comprising:
- an electronic apparatus main body having a conductive chassis;
- an operating device provided separately from the electronic apparatus main body, for operating the electronic apparatus main body, the operating device comprising:
- a printed circuit board;
- a plurality of connectors for external equipment, which are mounted on both ends of the printed circuit board, respectively, and through which the printed circuit board transmits or receives a signal while the external equipment is connected to at least one of the plurality of connectors;
- a conductive chassis plate which is disposed to face the printed circuit board at a distance, and has one end aligned with one end of the printed circuit board, and is electrically connected to a ground wiring pattern provided on the one end of the printed circuit board;
- and
- a conductive member which is electrically connected to the one end of the conductive chassis plate, and extends from the one end of the conductive chassis plate toward another end of the conductive chassis plate;
- and
- a conductive support member which supports the operating device so as to project from the electronic apparatus main body, and electrically connects the conductive chassis and the conductive chassis plate.
