となく、組み付け易く部品管理が容易になる電子機器の
パネル構造が提供される。As is apparent from the above description, according to the present invention, a panel case having a plurality of holes, and a light transmitting member having a projection fitted into each hole of the panel case,
In a panel structure of an electronic device provided with a plurality of light emitting elements arranged at a predetermined position inside the light transmitting member, the light transmitting member is provided with an error between the pitch of each hole and the pitch of a protrusion fitted thereto. Since a flexible portion for absorbing is provided, even if there is a pitch error between the pitch of the plurality of holes formed in the panel case and the pitch of the plurality of protrusions fitted in the holes, this It is possible to absorb the pitch error, improve the appearance of the fitting part and relax the pitch dimensional accuracy, and the panel structure of the electronic device is easy to assemble and the parts management is easy with almost no increase in cost. Provided.
