Data retaining apparatus for a camera

摘要

A data retention apparatus which protects against loss of data from the data processing circuits of a camera during replacement of the camera battery. A non-volatile memory, such as an E2 PROM, is arranged to receive data from the data processing circuits when the camera's battery cover is opened. An operating member holds the camera battery against it s contacts when the cover is opened so that data transfer can take place. Thereafter the operating member can be operated to release the battery.
