ABSTRACT:
An accessory which is mountable on a camera having film frame count data communication capability, and which can print film frame count data on a film surface comprises a detector for detecting a photographing signal generated with each photographing operation of the camera, a data reception device for receiving film frame count data from the camera by communication with the camera; and a storage device for storing film frame count data based on film frame count data received from the camera. When the detector detects the photographing signal, the storage device increments film frame count data stored therein by a value corresponding to one frame, and when the data reception device receives film frame count data from the camera, the storage device stores the received film frame count data in place of the film frame count data presently stored therein.
