Abstract: PURPOSE:To perform appropriate light emission and exposure in high probability by deciding a divided area which is not used for dimming in the case of normal light emission by using the photometric output and the emitted light quantity of a preliminary light emitter at a final stage and performing the normal light emission. CONSTITUTION:When preliminary light emission is performed the photometry of reflected light from the plurally divided areas of a field is performed to obtain the photometric output of every area from divisional photometry means 8a-8e. Then, the outputs from the divisional photometry elements 8a-8e are fetched in a photometric circuit 34, and in the case that at least one of the photometric outputs therefrom attains a specified value, the emitted light quantity is decreased and the preliminary light emission is performed again. The preliminary light emission in a state where the emitted light quantity is decreased is repeated until the photometric output which attains the specified value does not exist. By using the photometric output and the emitted light quantity at the time of performing the repeated preliminary light emission at the final stage, the divide area which is not used for dimming in the case of the normal light emission is decided. Thus, the appropriate light emission and exposure are performed in light probability.

Filed: 1993-07-05
Abstract: PURPOSE:To prevent malfunction or damage of a mechanism by making the position of the back end of a cassette at the time of starting to pull-in the cassette become constant independent of the kind of cassettes when the cassette in different size are inserted. CONSTITUTION:When the small cassette 33 is inserted to a cassette holder 10 from a cassette inserting window 8 of an outside case member 9, the cassette 33 is never brought into contact with a cassette detecting lever 27 since the horizontal width of the cassette is narrow. Therefore, a switch 29 for detecting cassette size does not perform the changeover operation. The cassette 33 is further inserted, and at the time when the back end 33a of cassette is attained to the position almost coincident with that of the cassette inserting window 8, a lever 30 for detecting cassette insertion is operated for turning by the cassette holder 10 to changeover a switch 32 for detecting cassette insertion. At this time point, the insertion of the small cassette is discriminated. Next, when the large cassette 34 is inserted, the switch 29 is changed over by the lever 27, therefore, the insertion of the large cassette is detected.

Title: Polar linear actuator
Inventor: NAKAUCHI SHUNSAKU
IPC: H01F7/20
Filed: 1993-07-05
Abstract: PURPOSE:To provide a high response polar linear actuator. CONSTITUTION:Two attracting members 2U, 2D are arranged oppositely such that the members 2U, 2D attract one core 3, moving literally between two members 2U, 2D, in the opposite directions. Flux from permanent magnets IU, ID is then passed through the magnetic bodies 9UR, 9UL, 9DR, 9DL in two attracting members 2U, 2D in the direction perpendicular to the moving direction of the movable core 3. Flux generated through excitation of coils 4UR, 4UL, 4DR, 4DL is added thereto for one magnetic body and subtracted therefrom for the other magnetic body. Flux from the permanent magnets passes in the same direction through both magnetic body. Consequently, the flux density in the gap varies between both magnetic bodies upon excitation of the coil to shift the movable core. Since the movable cores 3 are coupled through a light coupling rod 11 to provide a low mass movable part, the ratio of mass to the output decreases and the response is enhanced.
