Abstract
In an optical apparatus having a group of contacts for electrical connection with another apparatus, a plurality of contacts for communication are disposed between a power-supply contact and a grounding contact; the power-supply and grounding contacts are spaced at a larger distance away from adjoining communication contacts than the spacing distance provided between communication contacts; the group of contacts are electrically connected by spring members to patterns formed on a contact substrate; and the width of patterns provided for the power-supply and grounding contacts is arranged to be wider than the width of patterns for the communication contacts.
Claims20
An optical apparatus comprising a group of connection contacts arcuately disposed on said optical apparatus for electrical connection to another apparatus, said group of connection contacts comprising a power-supply contact, a grounding contact and a plurality of communication contacts disposed between said power-supply contact and said grounding contact, wherein an angular displacement between said power-supply contact and a communication contact among said plurality of communication contacts disposed adjacent thereto and an angular displacement between said grounding contact and a communication contact disposed adjacent thereto are arranged to be greater than an angular displacement between each of said communication contacts wherein said connection contacts make electrical connection with like contacts disposed on said another apparatus when said optical apparatus and said another apparatus are rotatably coupled.
