Abstract: PURPOSE:To cut off power supply automatically upon ending of developing of the photographed parts of a film by measuring the prescribed feed length of the film and automatically cutting off the power source upon detecting of the smallest one of a film loop in case when a power switch is turned off. CONSTITUTION:A detecting microswtich 234 of a loop detector which detects the amount of a looplike film in a film take-up chamber of a camera unit is provided right after the film inlet of a processor unit, and when there is no more loop at the point of the time when a powe switch is turned off upon ending of photographing, a switch 234 operates and the motor on the camera side is operated by the signal from this switch 234, whereby the film is fed by one frame. On the other hand, the pulse signals from a film feed detecting microswitch 279 of the processor unit are counted by a counter 410 and when they are counted by a prescribed number, a relay RL2 turns on, by which the supply of the power source to the entire device is cut off.

Abstract: PURPOSE:To transport a sheetlike copy automatically by a method wherein the trouble in a detector detecting the presence of the sheet is detected by the pulse counting of a counter. CONSTITUTION:When a start switch 30 is operated to begin the transportation of the copy, and a detector 16 is put in a condition of ''ON'' in spite of absence of the copy at the detecting position of the first detector 16, a signal is outputted from the detector 16 to open an AND gate A2 if the counted value of a first counter C1 is smaller than a preset value L. A driving roller is stopped by this output signal. On the other hand, a flip flop F3 is set by the output signal of the AND gate A2 and a trouble indicator 33 indicates the trouble. The condition of a trouble in the second detector 17 may be indicated in the same operation.

Abstract: PURPOSE:To make it possible to take out a one-reel film after shooting easily and then to utilize it immediately by detecting the rest of the film in a supply part and then by cutting off the electric power supply after the one-reel film is all taken up when the detected value of the rest is less than a prescribed value. CONSTITUTION:Film-rest detection lever 16 provided to supply reel 10 detects the film being less than prescribed length L' (when the length between A and B in the figure is denoted as L, L

Abstract: PURPOSE:To position the center of sheet material accurately to reference position by providing two detectors along the sheet material conveying path and controlling conveying rollers by the outputs thereof. CONSTITUTION:The 1st detector 20 is disposed in the position coinciding with the lens optical axis (a) of a camera 15 along the conveying belt 6 being turned by a conveying roller 7, and the 2nd detector 21 in the position just before the 1st detector 20 with respect to the conveying direction of the sheet material 2 and spaced from the 1st detector 20 at the distance longer that the length of the half the sheet material 2 having the maximum length at least in the conveying direction. As a result of this, the leading and trailing ends of the sheet 2 having been conveyed by conveying belts 3, 6 are detected by the 2nd and 1st detectors 21, 20. Based on the detection values thereof, the 2nd counter 31 counts the pulses of the number corresponding to the sheet material 2 length and when the divided value thereof and the calculated value of the 1st counter 30 coincide, a conveying roller drive motor 35' is stopped and the sheet 2 is stopped with its center being aligned to the lens optical axis (a).

Abstract: PURPOSE:To enable various recordings meeting use objects to be performed by covering the back of the original through the use of the sheet provided with the surfaces having the different characteristics of reflecting or absorbing light of the photosensitive wavelength region of recording madia on the front and back. CONSTITUTION:In the apparatus of recording the original 6 in a recording medium F, the one surface of a sheet 5 which is provided removably in the recess of an original platen 1 has the surface of the characteristic of reflecting light of the wavelength region sensitizing to microfilms and the opposite one surface has the surface of the caracteristic of absorbing light of the foregoin wavelength region. Both surfaces has the size larger than the original 6. A frame 20 for positioning the original 6 is provided on both surfaces of the sheet. By changing the surfaces of the original back sheet constituted in this way, the various recordings meeting use objects may be performed and further the exchange is easy and the work becomes simple.

Abstract: PURPOSE:To shorten film travel distance, miniaturize the device and evenly develop the entire surface of the film by spraying developing solution on the film on the slope which is inclined upward toward the advancing direction of the film. CONSTITUTION:The film F having been exposed by the camera enters a solution reservoir vessel 361 and makes uniform contact with the developing solution in the vessel 361. Next, the developing solution is sprayed onto the film emulsion surface by a nozzle 370 on the inclined plane 362, whereby the development is accelerated. In this case, the developing solution is injected in the direction opposite from the advancing direction of the film and therefore, the development is accelerated more as compared to other development systems. Hence, the travel distance of the film may be made relatively short and the film developed sufficiently, thus the entire surface of the film is evenly developed. If the film feed speed is the same, the apparatus may be made smaller than before.

Abstract: PURPOSE:To imprint various kinds of information to film with a simple constitution by providing a counter which permits arbitrary setting of contents and an optical means which imprinte the contents thereof to the film. CONSTITUTION:The read character ring 136, number imprinting ring 137 and read character ring 135 arrayed parallel with a plurality of character barrels constituting a decimal counter which counts the number of photographing frames, a drive ring 135 which drives the number imprinting ring 137 and the imprinting optical system consisting of a lamp 138, first, second mirrors 146, 147, imaging lens 148, etc. are provided in the lower part of a camera unit 1. Then when various kinds of code information are set in the decimal counter 134 driving the drive ring 135, imprinting on the film F by way of the imprinting optical system becomes feasible. In addition, the drive ring 135 cooperated to the film feed, by which the decimal counter 134 is automatically advanced and the frame number is continuously imprinted on the film F.
