PURPOSE:To ensure the effective use of a space produced in the direction of an optical axis, with a simple structure, by providing a connector having a movable contact bar which can be biased elastically along the cylindrical surface of a fixed lens barrel and the radial direction of the lens barrel. CONSTITUTION:A fixed lens protecting barrel part 7 is formed between a mobile lens barrel 6 and a lens bayonet part 1, and a projection is formed at a part of the part 7. A contact holding member 10 is put into a cut part 9 formed at the projection 8. A mobile contact bar 12 which serves as a good electric conductor having the elasticity is fixed to the member 10. A contact 13 having extremely small electric resistance is connected to a free terminal of the bar 12. These member 10 and contact 12 are set together into a unit to form a connector. As a result, a space of the optical axis direction can be used effectively with a simple structure. |
