ABSTRACT:
A sliding mechanism of a lens barrier, a lens barrier, and a camera have a simplified structure and can be readily downsized. An imaging apparatus has an imaging lens which focuses light to form an image. The lens barrier serves to cover the imaging lens from outside and is mounted on a main body of the imaging apparatus. The sliding mechanism of the lens barrier includes plural cam grooves and plural engaging members. The plural cam grooves are formed on a surface, which faces the main body of the imaging apparatus, of the lens barrier. The plural cam grooves have substantially parallel trajectories. The plural engaging members are arranged in the main body of the imaging apparatus and contact with the bottom portions of the plural cam grooves at least at three positions. The plural engaging members guide the lens barrier along the sliding direction. The lens barrier further includes an inner barrier and an outer barrier. The inner barrier is attached to the main body of the imaging apparatus and is slidable along a predetermined direction. The outer barrier is detachably attached to a surface, which is different from the surface attached to the main body of the imaging apparatus, of the inner barrier. The outer barrier has a surface area at least larger than the imaging lens.
