Abstract
In a photographic camera, a single electric motor serves as the only electro-mechanical transducer in an exposure adjusting device and also performs at least two other non-contemporaneous functions, such as a film advancing and/or shutter cocking function, and a shutter releasing function.
Claims13
In a camera adapted to receive a film element that is advanceable incrementally to successive exposure positions, said camera including:
- (a) a motor;
- (b) control means for controlling the mode of performance of the motor;
- (c) an exposure regulating device adjustable in accordance with luminance;
- and
- (d) a shutter releasable from a cocked condition to produce an exposure, the improvement comprising:
- (1) first means operable for causing the motor to advance the film element received by the camera,
- (2) second means operable for translating a particular mode of performance of the motor into a corresponding adjustment of the exposure regulating device in accordance with luminance,
- (3) third means operable for causing the motor to release the shutter, and
- (4) sequencing means for operating said first, second and third means sequentially and non-contemporaneously.

In a camera adapted to receive a film element that is advanceable incrementally to successive exposure positions, said camera including:
- (a) a motor;
- (b) an exposure regulating device adjustable in accordance with luminance;
- and
- (c) a shutter releasable from a cocked condition to produce an exposure, the improvement comprising:
- coordinating means selectively adjustable to:
- (1) an adjusting mode of operation in which the motor is operatively coupled to the exposure regulating device for adjusting the exposure regulating device in accordance with luminance but is ineffective to release the shutter and/or to advance the film element,
- (2) a shutter releasing mode of operation in which the motor is operatively coupled to the shutter for releasing the shutter from its cocked condition to produce an exposure, but is ineffective to advance the film element and/or to adjust the exposure regulating device in accordance with luminance,
- (3) a film advancing mode of operation in which the motor is operatively coupled to the film element received by the camera for advancing the film element but is ineffective to release the shutter and/or to adjust the exposure regulating device according to scene luminance, and
- sequencing means for sequentially adjusting said coordinating means to said adjusting, shutter releasing and film advancing modes of operation.
