ABSTRACT:
A release device for unlocking the back-cover of a camera includes a back-cover lock member urged in a direction to lock the back-cover, an operating lever pivotally disposed along a side of the camera and operable externally of the camera so as to be angularly displaced therefrom and an interlocking plate for interlocking the operating lever with the back-cover lock member. The operating lever is engageable with the interlocking plate after the operating lever is angularly rotated through a predetermined preliminary angle in an opening direction from a position where the operating lever is disposed along the camera body so as to displace the interlocking plate and to correspondingly displace the lock member to thereby unlock the back-cover. The interlocking plate is interlocked with a film rewind shaft so as to move the film rewind shaft in a direction to disengage the shaft from a film cartridge in accordance with the movement of the back-cover lock member to its unlocked position when the operating lever has been rotated beyond the predetermined preliminary angle.
