摘要： The present invention relates to a braking device for a focal plane shutter in a camera. In the early stage of a braking operation on a shutter curtain, a relatively weak braking force is applied, and in the closing stage of the braking operation, a strong braking force is applied to insure that without causing the shutter curtain to bounce or to be damaged by shock, the shutter curtain is stopped. The device is constructed from two brake members arranged so that in the early stage the first brake member takes action, and in the closing stage, the second brake member takes action to add a braking force to that of the first brake member.

摘要： In a focal plane shutter of the kind having a plurality of divided blades pivotally arranged to be turnable on driving arms in an overlapped state, the weight of the blades is reduced by making them from very thin material; the blades are reinforced with embossed protrusions which are formed in the longitudinal direction of the blades for the purpose of preventing them from flexing and being damaged during their travel. Each of the embossed protrusions is within the difference in stepped height between the surfaces of the blades and the heads of blade carrying studs disposed on the driving arms. Therefore, the shutter can be smoothly operated without increasing the thickness of the blades as a whole.

摘要： A camera is capable of forming different photographic image plane frames by causing a light blocking member which is movable in at least a photographic optical path to block part of a photographic light flux. The camera is provided with an urging member for imparting an urging force to the light blocking member, the direction of the urging force being changed when the light block member is located at a particular position in its movement course, a switching member arranged to switch its state at a point in a process in which the light blocking member moves from its maximum retracted position where the smallest amount of light flux is blocked to the particular position, and a display member for visually displaying the state of movement of the light blocking member, i.e., which of the photographic image plane frames has been formed, in accordance with the state of the switching member. In the above arrangement, during a photographic image plane frame switching operation, even if the light blocking member stops at or near the particular position and an imperfect photographic image plane frame is formed, a photographer can be informed that the photographic image plane frame as formed at least does not correspond to a photographic image plane frame state obtainable when the light blocking member is located at the maximum retracted position.

摘要： An output correction method for a proportional-output type O.sub.2 sensor including an oxygen concentration detecting element formed by an oxygen-pumping element and a cell element, each of the oxygen-pumping element and the cell element being composed of a wall of a solid electrolytic material having oxygen ion-conductivity, and a pair of electrodes having the wall interposed therebetween. The oxgen-pumping element is supplied with an output voltage corresponding to a difference between a voltage developed between the electrodes of the cell element and a predetermined reference voltage, and current flowing in the oxygen-pumping element is detected. A correction resistance supplies information indicative of a deviation of an air-fuel ratio detected by the sensor with respect to a predetermined reference air-fuel ratio. A correction value is determined on the basis of the information and the direction of flow of the current. The detected current is corrected by the use of the determined corrected value. A desired air-fuel ratio is calculated on the basis of the corrected current.
