Abstract
Abstract An information input device for a camera including a contact disposed in the vicinity of a patrone chamber in contact with the outer circumference of a patrone (film cartridge), a protecting member which moves between at least a first position for protecting the contact and a second position for exposing the contact, and a moving device for moving the protecting member between at least the first and the second positions according to an exposure operation of the camera. The protecting member slides over a contact area which is in contact with the patrone during its moving process between the first and the second positions.
