A container unit is composed of a lid and a unit body. A holder is a concave portion formed at a lower portion of the unit body. The lid is exposed at a lower surface of a camera body. The lid is slidable between a lock position where the lid is adjacent to a first inner surface of the holder, and a release position where the lid is adjacent to a second inner surface of the holder opposite to the first inner surface. An end portion of the lid is provided with a rotary shaft. Both ends of the rotary shaft engage with two elongate holes formed in lateral sides of the holder. The lid is slidably and rotatably retained by the holder.
