Filmstrip metering device for a camera

The camera according to claim 10, further comprising:

• a shutter cocking lever disposed in the path of movement of said wind-up member so as to be moved from a release position to a cocked position as the wind-up member is moved to its winding position, said shutter cocking lever having a release sensor thereon disposed out of the path of movement of said wind-up member and being moved together with said shutter cocking lever;
• an operating lever being mounted on the camera for pivotal movement between first and second positions, said operating lever in its first position being in engagement with said release sensor while said shutter cocking lever is in its release position, said release sensor moving away from said operating lever when said shutter cocking lever is cocked thereby permitting said operating lever to move into its second position, said operating lever in its second position bearing against said locking lever for locking it in the second position thereof;
• and
• a resetting lever pivotally mounted on the camera for bearing against said sensing member for retracting said sensing portion thereof away from the filmstrip in an initial phase of operation of said wind-up member as it is moved from its rest to its winding position.

A filmstrip metering device for a camera having a camera body housing a filmstrip having a single perforation for each frame thereof, the device including:

• a wind-up member movable from a rest position to a film wind-up position;
• a rotatable wind-up gear coupled with the filmstrip for winding up the filmstrip upon rotation of said gear;
• a sensing member movably mounted on the camera body;
• means resiliently urging said sensing member into engagement with the filmstrip, said sensing member being movable from a retracted position engaging said filmstrip through an extended position extending into one of said perforations and to a metering position moved a predetermined amount from said extended position as the filmstrip is being wound;
• a locking lever operatively coupled with said sensing member for movement from an active position to an inactive position in response to the movement of said sensing member from its extended to its metering position;
• means for transmitting the movement of said wind-up member toward its wind-up position to said wind-up gear for rotating same;
• the improvement comprising:
• said transmitting means including a rotatable first gear engageable with said wind-up member;
• first biasing means for urging said first gear into engagement with said wind-up member so that said first gear is rotated by the movement of said wind-up member toward its wind-up position;
• a first lever rotatably supporting said first gear and being pivotable from a first position to a second position respectively disengaging and engaging said first gear from and with said wind-up member;
• a shaft mounted on the camera body;
• a second lever mounted on said shaft for pivotal movement from a first position to a second position respectively disengaged from and engaged with said locking lever when in its active position;
• an intermediate gear mounted for rotation on said shaft and being operatively coupled with said wind-up gear for rotating same, said intermediate gear being maintained non-rotatable by a load exerted thereon from the filmstrip through said wind-up gear until a wind-up force greater than said load is exerted thereon from said wind-up member;
• and
• a second gear engaged with said first and intermediate gears and being rotatably supported on said first and second levers,
• whereby said second gear is moved along said intermediate gear due to the rotation of said first gear for pivoting said first and second levers from their first to their second positions, and when having reached their second positions, said first and second levers are maintained stationary relative to the camera body, so that said load exerted on said intermediate gear is likewise exerted on said first gear through said second gear to completely engage said first gear with said wind-up member, and whereby said wind-up force is exerted from said wind-up member on said intermediate gear through said first and second gears to rotate said intermediate gear for a film wind-up operation, and said second gear is further movable along said intermediate gear due to the rotation of said first gear when said locking lever is moved to its inactive position to be disengaged from said second lever, and said first and second levers being further movable to a third position due to the further movement of said second gear so that said first gear is disengaged from said wind-up member.
