  • Patent number: 5574528
    Abstract: The present invention relates to a camera which is capable of easily performing the film replacement even if it is in a dark place. This camera is equipped with an illuminating lamp in a patrone compartment within the camera or at the vicinity of the patrone compartment so as to lighten at least the patrone compartment with the lamp. In addition, this lamp turns on in response to a detection of a rear cover being opened, and turns off in response to a detection of the rear cover being closed. Moreover, a detector to detect an outside brightness is provided such that the lamp can be turned on when it has detected that the outside brightness is below a predetermined brightness. Thus, it is possible to offer a convenient camera.
