Abstract An interlocking device for the exposure meter in a camera includes a rotatable interlocking member engaging an exposure regulating member, a locking lever pivotally mounted on the interlocking member for rotation with the interlocking member, a needle scanning member engageable with the interlocking member and movable in response to the rotation of the interlocking member and the locking lever to scan the position of the needle of the exposure meter, and a fixed locking member. The locking lever is moved with respect to the interlocking member by the movement of the latter when the scanning member is stopped, and that movement of the locking lever is imparted to the fixed locking member without exerting any great force upon the needle of the photoexposure meter. Another embodiment further provides means to make the movement substantially linear of the lever which is moved by the exposure control interlocking pin provided at the lens. Moreover, means are provided for reducing the gap between the needle of the exposure meter and the stepped portion of the interlocking lever before exposure adjustment.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
158 words
In a camera having a self-contained exposure meter and an exposure regulator for scanning the needle of the exposure meter to automatically determine the exposure, an interlocking device for the exposure meter comprising an interlocking member for connecting an exposure regulating member and a needle scanning member; a locking lever pivotally mounted on said interlocking member for movement in response to movement of said interlocking member; and a fixed locking member against which said locking lever abuts to limit movement of said interlocking member, said locking lever and said needle scanning member; said needle scanning member moving in response to the rotation of said interlocking member and said locking lever to thereby scan the position of said needle, said locking lever being moved relative to said interlocking member by the mOvement of the latter when said scanning member is stopped, said movement of said locking lever being arrested by said fixed locking member, thereby providing an abutment-like support.
Claim 2
Dependent Claim
158 words
In a camera having a self-contained exposure meter and an exposure regulator for scanning the needle of the exposure meter to automatically determine the exposure, an interlocking device for the exposure meter comprising an interlocking member for connecting an exposure regulating member and a needle scanning member; a locking lever pivotally mounted on said interlocking member for movement in response to movement of said interlocking member; and a fixed locking member against which said locking lever abuts to limit movement of said interlocking member, said locking lever and said needle scanning member; said needle scanning member moving in response to the rotation of said interlocking member and said locking lever to thereby scan the position of said needle, said locking lever being moved relative to said interlocking member by the mOvement of the latter when said scanning member is stopped, said movement of said locking lever being arrested by said fixed locking member, thereby providing an abutment-like support.
Claim 3
Dependent Claim
68 words
An interlocking device for the exposure meter according to claim 1, the device further comprises a lever engaged at its one end with an exposure control interlocking pin provided at the exposure regulator, the lever being pivotally supported by said interlocking member and the other end of said lever being slidably moved within an elongated groove so as to move said one end of the lever substantially linearly.
Claim 4
Dependent Claim
104 words
An interlocking device for the exposure meter according to claim 1, the device further comprises an interconnecting member rotatably supported by another lever and pivotally connected to said needle scanning member, said needle scanning member having a groove engaged with a fixed pin, said interconnecting member having a groove, and connected to an auxiliary lever having a coupling pin slidably mounted in said groove, the rotational movement of said interlocking member being transmitted to the needle scanning member as a linear movement through said auxiliary lever and said interconnecting member so as to reduce the gap between the needle and the needle scanning member.
