Claim 7

A camera as defined in claim 3 further comprising a rib on said camera wall means adjacent said opening and extending into said cavity for entering into the groove of a received battery holder, said rib having a surface facing away from said opening and toward the abutment surface of a received battery holder to block movement of the first end wall of the battery holder toward said opening.

Claim 8

In a camera having a housing which defines a first cavity for receiving at least one battery and a second cavity for receiving roll film, a door movable relative to said housing between open and closed positions to provide access to at least said second cavity, an electrical circuit, and a contact for engaging said battery to connect said battery to said circuit; the improvement comprising means for moving said battery relative to said contact in response to movement of said door between its open and closed positions so as to provide rubbing engagement between said contact and a received battery.

Claim 9

In a camera having a housing which defines a first cavity for receiving at least one battery and a second cavity for receiving roll film, a door movable relative to said housing between open and closed positions to provide access to at least said second cavity, an electrical circuit, and a contact for engaging said battery to connect said battery to said circuit; the improvement comprising means for moving said battery relative to said contact in response to movement of said door between its open and closed positions so as to provide rubbing engagement between said contact and a received battery.

Claim 10

A camera comprising: a housing having means for defining (1) a cavity for receiving at least one battery (2) an opening through which such a battery may be inserted into said cavity, and (3) a door movable relative to said housing between open and closed positions to respectively uncover and cover said opening, said cavity being dimensioned to permit movement of a received battery in said cavity; means on said housing for restricting such movement of a received battery between first and second positions when said door is in an open position; an electrical circuit; at least one electrical contact on said housing and extending into said cavity for connecting a received battery to said circuit; and means for moving a received battery relative to said contact to its first and second positions respectively in response to movement of said door between its open and closed positions so as to provide rubbing engagement between said contact and a received battery.

Claim 11

A camera comprising: a housing having means for defining (1) a cavity for receiving at least one battery (2) an opening through which such a battery may be inserted into said cavity, and (3) a door movable relative to said housing between open and closed positions to respectively uncover and cover said opening, said cavity being dimensioned to permit movement of a received battery in said cavity; means on said housing for restricting such movement of a received battery between first and second positions when said door is in an open position; an electrical circuit; at least one electrical contact on said housing and extending into said cavity for connecting a received battery to said circuit; and means for moving a received battery relative to said contact to its first and second positions respectively in response to movement of said door between its open and closed positions so as to provide rubbing engagement between said contact and a received battery.
