A camera includes a counter rotatable about a support shaft, a spring that urges the counter in a first rotation direction, a rotary member and a drive cam that rotate the counter in a direction opposite to the first rotation direction, a stopper rotatable about the support shaft, and a spring that urges the stopper in a second rotation direction. The counter includes an outer circumferential surface that changes an indication in a circumferential direction, and a first engagement portion including a plurality of projections. The stopper includes contact tabs that receive a force acting in a direction opposite to the second rotation direction from at least one of a film pack or a door, and an engagement tab engageable with one of the projections on the first engagement portion on the counter to restrict rotation of the counter in the first rotation direction.
