摘要： An encoder for detecting a forward/reverse movement of a rotatable object includes a rotating shaft that is supported on a base and rotates in accordance with the movement of the subject, two rotating disks fixed to the rotating shaft, and two photocouplers mounted on the base which are associated with the disks. Each of said rotating disks is formed with a predetermined light modulating pattern to vary the intensity of light along a circumferential direction. Each of the photocouplers emits a light toward the rotating disk and detects the light modulated by the pattern on the rotating disk. The angular relationship between the rotating disks is selected such that the output signals from the photocouplers due to the rotation of the rotating shaft have a predetermined phase difference.

Secondly, the male helicoid molding die is machined to form a helicoid portion thereof using the cutting tool. Next, an electric spark machining electrode is prepared having a helicoid portion whose shape is identical to a shape of the helicoid portion of the male helicoid molding die, by a mechanical cutting operation, using the cutting tool. Then a helicoid portion of the female helicoid molding die is formed by electric spark machining using the electric spark machining electrode.

摘要： The exposure controlling device comprises a controlling unit that controls, at the time of an exposure, the DC motor to rotate forward to open the shutter blades and then to rotate reversely to close the shutter blades, a calculating unit that calculates a time period for driving the DC motor in the forward direction between a predetermined starting point and a point where a required aperture area is obtained, a timer for counting the time period from the starting point, a memory for storing data of relationship between the time period and the aperture area, and means for storing an individual data of the relationship into the memory. The calculating unit calculates the time period based on a required aperture area by using the data of relationship stored in the memory for compensating individual differences among lens shutters.
