摘要： PURPOSE:To simplify the circuit and switch constitution and improve the reliability of focus adjustement, by stopping the travel of length setting member according to the relation between the pulse correspoinding to the angle of rotation of movable mirror and the pulses due to traveling of length setting member. CONSTITUTION:Along with traveling of a length setting member, a control signal ME becomes L, and reset of FFs33, 51, 54 and dividing circuit 25 is released, while light information on the fixed mirror side is stored in a focus detecting circuit. A pulse P corresponding to the angle of rotation of movable mirror is sent into a counter 41. Every time a peak detection signal PH becomes H, the content in the counter 41 is written in a counter 42. By traveling of the length setting member, a corresponding pulse P is added to a counter 42. When the signal P and signal PH are established in the specified relation in the counter 42, the traveling of the length setting member is stopped.

摘要： PURPOSE: To prevent the malfunction of a shutter and simplify the production by operating a circuit means, which determines an exposure corresponding to the luminance of an object, in accordance with a shutter opening/closing means.
CONSTITUTION: When the exposure time corresponding to the luminance of the object elapses, a capacitor of an exposure time setting circuit reaches a prescribed level, and an electromagnet 8 is degaussed. Then, an iron piece lever 7 starts turning clockwise by its own energizing force and presses the lower part of a blade opening lever 4 by a back pin 7a to turn it right, and detention of a blade lever 5 is released. Therefore, the lever 5 is turned right by its own energizing force while being controlled by a governor mechanism 11 again to close shutter blades 6 and 6 through a pin 5a. On the other hand, a sector wheel 10 is turned counterclockwise while following up the lever 5 and releases press of a leas piece 9a to return a timing switch 9 to the turn-on state again.

CONSTITUTION: When the exposure time corresponding to the luminance of the object elapses, charging of a capacitor reaches a prescribed level, and an electromagnet 8 is degaussed. Then, an iron piece lever 7 presses a lower sliding edge 6b of a blade opening lever 6 by a spring 7e to turn right it and disengages it from a blade lever 9. Therefore, the lever 9 is turned right by a spring 9d while being controlled by a governor again, and shutter blades 10 and 10 are closed through a pin 9b. Meanwhile, a sector wheel 11 is turned counterclockwise by the energizing force of a spring 11b while following up the lever 9, and therefore, a stood pin 11e releases press of a lead piece 12a to return a timing switch 12 to the turn-on state again.

摘要： PURPOSE:To increase the number of usable film classifications and to make an alarm indication possible to enhance the effect, by setting a specific film sensitivity of a relatively high frequency in use in case of a general cartridge which has not a code part. CONSTITUTION:When a general cartridge which has not a code part is loaded, the film sensitivity of ASA100 of a relatively high frequency in use is set, and a signal code G changes to H. Consequently, the signal from an oscillating circuit 47 is inputted to a transistor (TR) T7 through an AND circuit 40 and an OR circuit 42 to flicker an LED43. Meanwhile, when a cartridge which has a code part of ASA800-5,000 is loaded, a signal code E changes to H, and the LED43 is flickered similarly. Thus, the number of usuable film classifications is increased, and alarm indication is made possible, and the effect is enhanced.

摘要： PURPOSE:To decrease electric current for illumination by setting a projecting means on the position where the projecting means can be guided in the light path of a movable mirror in a range finder where two images consist with each other, and detecting the distance by switching to one photoelectric element and receiving the light of the luminous source after connecting plural photoelectric elements when the brightness of the subject is low. CONSTITUTION:The light from a subject is incident to photoelectric elements 4a- 4c through half mirror 1 and the output are entered into distance detecting circuit 12 through switches S1-S3 to store the output ratio of 4a and 4c to the output of photoelectric element 4b. When the distance measurement starts, actor 5 is opened and movable mirror 5 starts to rotate. When the similar output ratio of photoelectric element 4 consists with the stored value, the distance set point is outputted from the OR circuit. When the brightness of the subject is low, switch 11 is changed over as shown in a dotted line by the output from detecting circuit 16 and connected to detecting circuit 13 and reflection mirror 8 jumps up. At the same time, oscillation circuit 17 operates and the light of luminous source 7 is reflected by mirrors 8 and 2 to illuminate the subject. Thus, electric current for illumination can be reduced.

摘要： PURPOSE:To simplify construction and circuit by changing the input voltage level of an input terminal for reading codes so that the need for a manual selector switch is eliminated and the manual setting of film sensitivity is simultaneously accomplished with the same input terminal. CONSTITUTION:An input circuit part 11 for automatic setting with which film sensitivity is automatically set by a cartridge having a code part, an input circuit part 12 for manual setting with which the film sensitivity is set manually for a cartridge having no code part and an input terminal part 13 for inputting the information on the film sensitivity to the circuit in the stage of automatic setting and manual setting are provided. A level detecting part 14 detects wether the film sensitivity is automatically set or manually set. A selecting circuit 15 consists of five circuit blocks for input terminals S1-S5. An auto signal A and a manual signal A' are respectively inputted to the respective circuits as shown in the figure.
