Claims
- 1. A motor driving device of a camera comprising:
- a motor for driving a film winding mechanism;
- first means for outputting a holding signal in association with the film winding mechanism;
- second means for outputting a position signal in association with the film winding mechanism, the position signal representing that a film lies at a correct position for next photographing;
- first means for driving said motor;
- first means for detecting whether or not the holding signal is outputted, while said first driving means drives said motor;
- first means for braking said motor when said first detecting means detects that the holding signal is not outputted;
- second means for detecting, a predetermined time after said first braking means brakes said motor, whether or not the position signal is outputted;
- second means for again driving said motor when said second detecting means detects that the position signal is not outputted;
- third means for detecting, after said second driving means drives said motor whether or not the position signal is outputted; and
- second means for braking said motor when said third detecting means detects that the position signal is outputted.
- 2. A motor driving device of a camera according to claim 1, wherein the holding signal is stopped a slight time before the film reaches the correct position so that the film is moved by inertia of the film winding mechanism after the holding signal disappears.
- 3. A motor driving device of a camera comprising:
- a motor used for winding a film;
- first means for driving said motor to wind the film;
- first means for detecting whether or not the film is wound up by a predetermined length;
- first means for braking said motor when said first detecting means detects that the film is wound up by the predetermined length;
- means for outputting a signal representing that the film is wound up correctly;
- second means for detecting whether or not the signal is outputted, a predetermined time after said first braking means brakes said motor;
- second means for again driving said motor when said second detecting means detects that the signal is not outputted;
- third means for detecting whether or not the signal is outputted, after said second driving means drives said motor; and
- second means for braking said motor when said third detecting means detects that the signal is outputted.
- 4. A motor driving device of a camera comprising:
- a motor for driving a driving mechanism which drives a load of the camera;
- first means for outputting a holding signal in association with the driving mechanism;
- second means for outputting a position signal in association with the driving mechanism, the position signal representing that the load exists in a correct position;
- first means for driving said motor;
- first means for detecting whether or not the holding signal is outputted, while said first driving means drives said motor;
- first means for braking said motor when said first detecting means detects that the holding signal is not outputted;
- second means for detecting, a predetermined time after said first braking means brakes said motor, whether or not the position signal is outputted;
- second means for again driving said motor when said second detecting means detects that the position signal is not outputted;
- third means for detecting, after said second driving means drives said motor, whether or not the position signal is outputted; and
- second means for braking said motor when said third detecting means detects that the position signal is outputted.
- 5. A motor driving device of a camera comprising:
- a motor;
- first means for driving said motor to operate a load of the camera;
- first means for detecting whether or not the load is operated by a predetermined quantity;
- first means for braking said motor when said first detecting means detects that the load is operated by the predetermined quantity;
- means for outputting a signal representing that the load is operated correctly;
- second means for detecting whether or not the signal is outputted, a predetermined time after said first braking means brakes said motor;
- second means for driving said motor again when said second detecting means detects that the signal is not outputted;
- third means for detecting whether or not the signal is outputted, after said second driving means drives said motor; and
- second means for braking said motor when said third detecting means detects that the signal is outputted.
- 6. A motor driving device of a camera comprising:
- a motor for driving a camera load;
- means for driving said motor;
- means associated with said load for outputting a holding signal in response to said motor being driven;
- means associated with said load for outputting a correct position signal;
- means for braking said motor;
- processor means for activating said braking means upon detecting a disappearance of said holding signal, said processor means further including:
- means for detecting a predetermined time after said braking means has been activated, whether said correct position signal has been output, whereby if said correct position is not detected, said processor means causes said motor to again be driven without activation of said braking means until said correct position signal is detected whereupon said braking means is re-activated.
