Abstract

PURPOSE:To form a photosensitive image at a specified reduction rate without changing an optical length by detecting the size of an object and changing automatically the size of a window of an aperture which determines the exposing range on a photosensitive material. CONSTITUTION:If there is a photoelectric element 7 for detecting the size of an object exists behind an object 3, the resistance of the element 7 is so large that a transistor 22 does not conduct. When a shutter switch 24 is pushed, relays 25, 26 operate and a motor control circuit 27 runs a motor 11 for a device for measuring the size of the object and a motor 12 for moving a movable aperture. A movable aperture 15a moves rightward, thus expanding an exposing range. The element 7 moves toward the right as well, and when the element arrives at the edge 3a of the object 3, the quantity of incident light increases, the transistor 22 conducts and a relay 23 operates to stop the motor 11, 12 and the edge 3a of the object 3 is positioned exactly in the window frame of the aperture. The shutter opens and the object 3 is photographed on a film F.

When photographing various objects of different sizes with a flat-bed camera, the position of the camera is moved up and down depending on the size of the object, and the reduction ratio is changed. Conventionally, the method for this was to place the subject in one of several types of frames shown on the photographing stand, and then the operator moved the camera up and down to a position corresponding to the size of the frame to take the picture. , there is a risk of forgetting the operation to move it. To prevent this, a method was developed that uses a photoelectric device placed behind the subject to detect the size of the subject and uses that signal to move the camera to the appropriate position.

FIG. 3 shows an example of an electric control circuit, and 20 and 21 are AC power supply terminals. If the photoelectric element 7 for detecting the object size is located behind the object 3, only a small amount of the light beam that has passed through the object 3 will be incident, so the resistance of the photoelectric element 7 will be large and the transistor 22 will not conduct. Relay 23 does not operate and its contacts 23.・232 is on the NC terminal side in the figure. When the shutter switch 24 is pressed in this state, the relay 25 operates to close this contact 251, and the relay 26 also operates to close its contact 26. At the same time, the contact 262 is switched to the No side, and the motor control circuit 27 is connected to the object size measuring instrument motor 11,
The movable aperture moving motor 12 is rotated. The motors 11-12 rotate clockwise when widening the aperture and counterclockwise when vice versa. If the motor 11 now rotates clockwise, the movable aperture 15a will move to the right in FIG. 2, widening the exposure range, and at the same time the photoelectric element 7 will also move to the right in FIG.

When the photoelectric element 7 reaches the edge 3a of the subject 3, the amount of incident light suddenly increases and its resistance decreases, and the output fluctuation causes the transistor 22 to become conductive and the relay 23 to operate. Therefore, the contacts 231 and 232 are switched to the terminal No side, the relay 26 is restored, the contact 262 is opened from No, and the motors 11 and 12 are stopped. That is, the movable aperture 15 and the photoelectric element 7 also stop. In this state, the edge 3a of the subject 3 is located just within the aperture window frame.

Furthermore, if the photoelectric element 7 is placed outward from the edge 3a when the subject 3 is placed on the semitransparent plate 2, the resistance value of the element will decrease when a large amount of light rays are incident on the element. , transistor 22 becomes conductive, and relay 23
operates, and the contacts 23° and 232 are switched from the state shown in the figure to terminal No.

The relay 29 is activated by the closing of the relay 29. The relay 29 is self-held by the contact 29□, and the contact 292 is switched to the No side, and the motor control circuit 27 rotates the motors 11 and 12 to the left, opposite to the front. For this reason, the movable aperture 15
When a moves to the left in FIG. 2 and the photoelectric element 7 reaches the edge 3a of the subject 3, which has moved to the left in FIG. 1, the amount of incident light decreases rapidly. Due to the output fluctuation, the transistor 22 becomes non-conductive, the relay 23 is restored, and the contact 23

By adjusting the variable resistor 30 according to the brightness of the light source illuminating the subject 3, the transistor 22 can be reliably turned off when the photoelectric element 7 is behind the subject, and only the semitransparent plate 2 can be turned off. The on-operation potential of the transistor 22 is kept constant so that it becomes conductive when the transmitted light beam is incident.
