Abstract
In an electronic apparatus with a first case and a second case movable to opening/closing positions of the first case, there is provided electro-optical converting means at a portion of the first case which is located opposite to the second case when the second case is opened at a predetermined opening angle. The electro-optical converting means converts an electric signal obtained from a first electronic circuit employed in the first case into an optical signal. Then, an optical-electro converting means is employed at a portion of the second case which is located opposite to the electro-optical converting means when the second case is opened at a predetermined opening angle. The optical-electro converting means converts the optical signal produced from the electro-optical converting means into an electric signal. When the second case is opened at a predetermined opening angle, the signal transmission between a first electronic circuit employed in the first case and a second electronic circuit employed in the second case is carried out via the electro-optical converting means and optical-electro converting means.
