Abstract
Abstract A casing for retaining therein a series of dry cells is provided with cell holding members which hold the cells allowing movement in one direction of the cells, and a member for moving the cells in said direction. The direction in which the cells are made movable is lateral to the direction of connection of the cells connected in series in a line in the casing so that the electrodes of the cells connected with the electrodes adjacent thereto are abraded when the cells are moved in said direction by the movable member. The movable member may be a cover of the housing of the casing or other member associated with the shutter release mechanism or the like.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
A casing for retaining therein a series of dry cells for a photographic camera or the like comprising: a housing for retaining therein a series of dry cells connected in series in a line, a pair of oppositely disposed electrode springs provided on the opposite ends of the housing to sandwich the series of dry cells therebetween so that the series of dry cells arranged in a line are in pressure contact with each other, means for holding dry cells in the housing allowing the dry cells to transversely move independently of each other and urging said cells in one transverse direction, and means for moving said dry cells in the direction opposite to said transverse direction in which the cells are urged.
Claim 2
Dependent Claim
123 words
A casing for retaining therein a series of dry cells for a photographic camera or the like comprising: a housing for retaining therein a series of dry cells connected in series in a line, a pair of oppositely disposed electrode springs provided on the opposite ends of the housing to sandwich the series of dry cells therebetween so that the series of dry cells arranged in a line are in pressure contact with each other, means for holding dry cells in the housing allowing the dry cells to transversely move independently of each other and urging said cells in one transverse direction, and means for moving said dry cells in the direction opposite to said transverse direction in which the cells are urged.
Claim 3
Dependent Claim
44 words
A casing for retaining therein a series of dry cells as claimed in claim 1 wherein said dry cell holding means comprises a plurality of movable members to support said dry cells and spring means for urging the movable members in said transverse direction.
Claim 4
Dependent Claim
35 words
A casing for retaining therein a series of dry cells as claimed in claim 2 wherein said movable member for one cell has a different size from that of the movable member for another cell.
Claim 5
Dependent Claim
35 words
A casing for retaining therein a series of dry cells as claimed in claim 1 wherein said dry cell holding means comprises an elastic member elastically supporting the cell to allow the transverse movement thereof.
Claim 6
Dependent Claim
66 words
A casing for retaining therein a series of dry cells as claimed in claim 1 wherein said dry cell moving means is a cover movable to close and open the housing and said dry cell holding means holds the cells with the top portion thereof projected out of the housing so that the cells are pushed inward and moved transversely by the closure of the cover.
Claim 7
Dependent Claim
33 words
A casing for retaining therein a series of dry cells as claimed in claim 5 wherein said cover is a rigid cover hinged at an end thereof to an end of the housing.
Claim 8
Dependent Claim
42 words
A casing for retaining therein a series of dry cells as claimed in claim 5 wherein said cover is a rigid slidable cover having a slant end facing obliquely inward which is slidable on the housing to close and open the housing.
Claim 9
Dependent Claim
46 words
A casing for retaining therein a series of dry cells as claimed in claim 5 wherein said cover is a rigid cover movable in the direction parallel to said direction in which the cells are moved by said moving means to close and open the housing.
