Claim 2

Dependent Claim 201 words

A cell housing device capable of selectively housing a first cell relatively longer in length and elongated in the longitudinal direction or a second electric cell relatively greater in diameter and shorter in length, comprising: a housing chamber provided with an opening through which said first or second cell is inserted, and comprising a first housing portion having a depth sufficient to house said first cell and a relatively large cross sectional size corresponding to said second cell and a second housing portion being defined integral with said first housing portion and having a depth and a relatively small cross sectional size sufficient to house therein a portion of said first cell; a cover for closing or opening of said housing chamber; elastic means for biasing said first or second cell inserted into said housing chamber toward to said opening; engaging means which is extended inwardly into said opening of said housing chamber and temporarily engage one edge of the inserted cell against the biasing forces of said elastic means; and disengaging means provided on said cover and capable of releasing said temporarity engagement of said engaging means with said inserted cell in response to the closing action of said cover.

Claim 3

Dependent Claim 82 words

A cell housing device for a camera as set forth in claim 1, wherein said disengaging means includes a projection which is extended inwardly from the lower surface of said cover and is capable of engaging with said one edge of said cell and is inserted between said cell and the side walls of said housing chamber when said cover is closed so as to displace said one edge of said cell in the direction in which said cell is pushed out.

Claim 4

Dependent Claim 77 words

A cell housing device as set forth in claim 2, wherein said projection of said disengaging means has a leading end insertable between said one edge of said inserted cell and the side wall of said housing chamber and a tapered portion which is extended further integrally with said leading end and is capable of shifting said one edge of said inserted cell in the direction substantially perpendicular to the direction in which said cover is closed.

Claim 5

Dependent Claim 47 words

A cell housing device as set forth in claim 1, wherein said cover further includes an engaging member which is pressed against one end surface of said inserted cell when said cover is closed, thereby maintaining said inserted cell in a stationary state in said housing chamber.

Claim 6

Dependent Claim 58 words

A cell housing device as set forth in claim 1, wherein said cover further includes positioning means which is forced to contact with one end surface of said second cell inserted into said first housing portion in response to the closing operation of said cover, thereby displacing said second cell so as to adjust the housing position thereof.

Claim 7

Dependent Claim 139 words

A cell housing device for a camera comprising: a housing chamber in which is housed selectively one of a plurality types of electrical cells whose terminals or electrodes are spaced apart from each other by different distance and at least which are different in length; and electric contact establishment member comprising an electrical contact portion disposed within said housing chamber, a contact supporting portion supporting being displaced over a distance corresponding to the length of said cell inserted into said housing chamber so as to displace said electrical contact portion to the position of the electrode terminal of said inserted cell in response to the operation of inserting said cell into said housing chamber and an elastic spring portion for forcibly contacting said contact portion with said electrode or terminal of said inserted cell through said contact supporting portion.

Claim 8

Dependent Claim 139 words

A cell housing device for a camera comprising: a housing chamber in which is housed selectively one of a plurality types of electrical cells whose terminals or electrodes are spaced apart from each other by different distance and at least which are different in length; and electric contact establishment member comprising an electrical contact portion disposed within said housing chamber, a contact supporting portion supporting being displaced over a distance corresponding to the length of said cell inserted into said housing chamber so as to displace said electrical contact portion to the position of the electrode terminal of said inserted cell in response to the operation of inserting said cell into said housing chamber and an elastic spring portion for forcibly contacting said contact portion with said electrode or terminal of said inserted cell through said contact supporting portion.

Claim 9

Dependent Claim 88 words

A cell housing device as set forth in claim 6, wherein said elastic spring portion of said electrical contact establishment member comprises a torsion spring one end of which is securely anchored to the inner wall of said housing chamber; and said contact supporting portion is in the form of a rod extended integrally with the other end of said torsion spring in the direction in which said contact supporting portion intersects a coil shaft, one end of said rod-shaped contact supporting portion terminating into said contact portion.

Claim 10

Dependent Claim 54 words

A cell housing device as set forth in claim 6, wherein said housing chamber includes a cover member which can open or close an opening of said housing chamber through which is inserted a cell; and said electrical contact establishment member biases said inserted cell through said electrode or terminal toward said cover member.

Claim 11

Dependent Claim 112 words

A cell housing device for a camera comprising: a housing chamber into which is selectively housed one of a plurality types of cells which are different at least in length and have electrodes or terminals spaced apart from each other by different distances; an electrical contact capable of contacting in common with the electrode or terminal of any cell inserted into the housing chamber; means for displacing said contact over a length corresponding to the length of the cell housed in said housing chamber in response to the operation for inserting a cell into said housing chamber; and elastic spring means for forcibly contacting said electrical contact with said electrode or terminal.

Claim 12

Dependent Claim 112 words

A cell housing device for a camera comprising: a housing chamber into which is selectively housed one of a plurality types of cells which are different at least in length and have electrodes or terminals spaced apart from each other by different distances; an electrical contact capable of contacting in common with the electrode or terminal of any cell inserted into the housing chamber; means for displacing said contact over a length corresponding to the length of the cell housed in said housing chamber in response to the operation for inserting a cell into said housing chamber; and elastic spring means for forcibly contacting said electrical contact with said electrode or terminal.

Claim 13

Dependent Claim 80 words

A cell housing device as set forth in claim 9, wherein said elastic spring means comprises a torsion spring whose one end is securely anchored to the inner wall of said housing chamber; and said contact displacing means in the form of a rod extended integrally from the other end of said torsion spring in the direction which said contact displacing means intersect a coil shaft, the leading end of said contact displacing means being terminated into said electrical contact.

Claim 14

Dependent Claim 57 words

A cell housing device as set forth in claim 9, further comprising a cover member which can open or close an opening of said housing chamber through which a cell is inserted into housing chamber; and said elastic spring means biases said inserted cell through said electrical contact and said electrode or terminal toward said cover member.
