ABSTRACT:
A cell housing device for a camera has a housing chamber defined in a camera body and capable of housing therein one of two types of cells different in shape and comprising a first housing portion which are defined by first side walls and has a cross section and depth adapted to house therein a second cell relatively greater in diameter and short and a second housing portion which is further extended downwardly from said first housing portion and is defined by second side walls and has a cross section and depth adapted to house therein the lower portion of a first cell which is longer than the second cell. Furthermore the cell housing device is provided with a cover capable of opening or closing the cell insertion opening of said housing chamber, elastic means for pressing against the inserted cell toward the cover, means extended from the inner wall of the housing chamber in the vicinity of the cell insertion opening thereof and capable of temporarily engaging with the edge of the upper end surface of the inserted cell against the biasing forces of the elastic means and means extended inwardly from the lower surface of the cover for releasing the engagement of the inserted cell with the first mentioned means in response to the operation for closing the cover.
