Camera with motor driven winding-up device

Claim 2

A motor driven winding-up device for a camera with a shutter including: (a) an electric motor; (b) a spool arranged to be driven by said motor for winding up film in the camera; (c) clutch means for transmitting driving torque of said motor to said spool so that said spool is driven to rotate when said clutch means is actuated, said clutch means being placed in a non-actuated state when a film is wound up by a length of one frame; (d) switching means for controlling a supply of current to said motor when said switching means is actuated, said switching means being placed in a non-actuated state corresponding to completion of energizing the shutter; (e) an actuating member for selectively actuating said clutch means and said switching means by shifting in a prescribed direction; and (f) a latch member engageable with said actuating member, and arranged to be disengaged from said actuating member when operation of the shutter is completed, for initiating shifting of said actuating member.

Claim 3

A device according to claim 1, wherein said latch member is supported in a freely rotatable manner and is rotated corresponding to completion of the operation of the shutter so as to release engagement thereof with said actuating member.

Claim 4

A device according to claim 2, wherein said latch member is biased in a direction for engaging said actuating member.

Claim 5

A device according to claim 3, wherein said latch member is arranged to rotate by contacting an element associated with the shutter when the operation of the shutter is completed.

Claim 6

A motor driven winding-up device for a camera including: (a) an electric motor; (b) a spool arranged to be driven by said motor for winding up film in the camera; (c) clutch means for transmitting driving torque of said motor to said spool so that said spool is driven to rotate when said clutch means is actuated; (d) switching means for controlling a supply of current to said motor when said switching means is actuated; (e) an actuating member for selectively actuating said clutch means and said switching means; (f) a latch member for latching said actuating member, said latch member being arranged to be disengaged from said actuating member when an exposure operation of the camera is terminated; (g) a release member operating in response to actuation of a camera release operation; and (h) a lock member arranged to be engageable with said release member for preventing movement of said release member, said lock member being arranged to be disengaged from said release member as said actuating member engages said latch member.

Claim 7

A motor driven winding-up device for a camera including: (a) an electric motor; (b) a spool arranged to be driven by said motor for winding up film in the camera; (c) clutch means for transmitting driving torque of said motor to said spool so that said spool is driven to rotate when said clutch means is actuated; (d) switching means for controlling a supply of current to said motor when said switching means is actuated; (e) an actuating member for selectively actuating said clutch means and said switching means; (f) a latch member for latching said actuating member, said latch member being arranged to be disengaged from said actuating member when an exposure operation of the camera is terminated; (g) a release member operating in response to actuation of a camera release operation; and (h) a lock member arranged to be engageable with said release member for preventing movement of said release member, said lock member being arranged to be disengaged from said release member as said actuating member engages said latch member.

Claim 8

A device according to claim 5, wherein said motor driven winding-up device for a camera further includes: (a) a response member, said member being actuated by said latch member; and (b) bias means, said means transmitting the action of said response member to said lock member.

Claim 9

A motor driven winding-up device for a camera including: (a) an electric motor; (b) a spool arranged to be driven by said motor for winding up film in the camera; (c) clutch means for transmitting driving torque of said motor to said spool so that said spool is driven to rotate when said clutch means is actuated; (d) switching means for controlling a supply of current to said motor when said switching means is actuated; (e) a first actuating member for actuating said switching means; (f) a first latch member for latching said first actuating member; (g) a second actuating member responsive to release of said first actuating member and said first latch member from engagement with each other, for actuating said clutch means in a direction toward a transmitting state; (h) a rewind control member for releasing said first latch member and said first actuating member from engagement with each other; and (i) a third actuating member cooperative with said rewind control member for latching said second actuating member.

Claim 10

A motor driven winding-up device for a camera including: (a) an electric motor; (b) a spool arranged to be driven by said motor for winding up film in the camera; (c) clutch means for transmitting driving torque of said motor to said spool so that said spool is driven to rotate when said clutch means is actuated; (d) switching means for controlling a supply of current to said motor when said switching means is actuated; (e) a first actuating member for actuating said switching means; (f) a first latch member for latching said first actuating member; (g) a second actuating member responsive to release of said first actuating member and said first latch member from engagement with each other, for actuating said clutch means in a direction toward a transmitting state; (h) a rewind control member for releasing said first latch member and said first actuating member from engagement with each other; and (i) a third actuating member cooperative with said rewind control member for latching said second actuating member.

Claim 11

A device according to claim 7, wherein said motor driven winding-up device for a camera further includes: (a) a second latch member engaging said third actuating member when said third actuating member is actuated by said rewind control member.

Claim 12

A device according to claim 8, wherein said motor driven winding-up device for a camera further includes: (a) a release member operating in response to actuation of a camera release operation; and (b) a lock member arranged to be engageable with said release member for preventing movement of said release member, said lock member being arranged to be disengaged from said release member when said first actuating member engages said first latch member.

Claim 13

A device according to claim 9, wherein said second latch member and said third actuating member are released from engagement with each other by the action of said release member.
