Patent ID: 7905662

Claim:
A connecting device for connecting a signal transfer path to a connection target component in such a manner that a signal is capable of being transferred therebetween, the connecting device comprising: the signal transfer path that is to be connected to the connection target component; and a moving portion that has therein a sealed space, the moving portion moving an end portion of the signal transfer path closer to the connection target component so that the end portion is connected to the connection target component with signal transfer being possible therebetween in response to an increase in a pressure of a gas in the sealed space of the moving portion, the moving portion moving the end portion away from the connection target component in response to a decrease in the pressure in the sealed space of the moving portion, wherein the signal transfer path is an optical waveguide, and the moving portion moves the end portion of the optical waveguide closer to the connection target component in response to the increase in the pressure within the sealed space of the moving portion, so that the end portion of the optical waveguide and the connection target component are optically connected to each other.
