Abstract: A storage chamber for temporally storing elongate web is provided between exposure device for imagewisely exposing the elongate web and developing device. After the amount of web in the storage chamber has reached a preset amount, the web is fed from the storage chamber to the developing device, and feeding device is stopped when development of the trailing end of the final exposed section on the web has been terminated after the feed of the web to the developing device has been started.

Abstract: A device in which a light source and a light receiving element are disposed at one side of a sheet transportation path and a reflecting member is disposed at the other side of the sheet transportation path so that a light ray emitted from the light source is reflected by the reflecting surface of the reflecting member and is caused to enter the light receiving element and any variation in the quantity of light entering the light receiving element is detected to thereby detect the presence of a sheet. The reflecting member is disposed such that the angle formed by the normal to the reflecting member with the surface of the sheet placed at the detection position is equal to or smaller than the critical angle at which total reflection is created on the surface of the sheet.

Abstract: An apparatus for detecting the length of web wound on a bobbin. The apparatus detects the amount of rotation of the bobbin and the amount of feed of the web and detects the amount of roll by an operation on the basis of the detected amounts. The amount of rotation of the bobbin is detected by the pulses generated in response to the rotation of the bobbin and counted by a first counter. The amount of feed of the web is detected by the pulses generated in response to the feeding of the web and counted by a second counter. The amount of roll is calculated by an operation device on the basis of the count values of the first and second counters.

Abstract: This specification discloses an apparatus for photographing originals successively on a long footage of film. Originals of various sizes such as checks, stock-certificates, vouchers, etc. are photographed on the film. When originals of various sizes are photographed on unphotographed film, how may originals can be photographed on the unphotographed film is displayed. The number of originals photographable on the unphotographed film can be known for each size of original and can also be known as the number of originals having an average size which have hitherto been photographed or as the number of originals having a minimum or a maximum size. Also, in a photographing apparatus wherein photographed film is temporally stored in a storage portion and then fed to a developing portion, how many originals can be photographed on the film that is to be stored in the storage portion is displayed.

Abstract: A photographic apparatus, in which a plurality of image originals are sequentially photographed on a photographic film of a long length, and the thus photographed film is subjected to development. The photographic apparatus is provided with a film storage chamber, where the exposed film is temporarily stored, and the film stored therein is gradually fed by means of film forwarding rollers which operate in accordance with the film quantity staying in the film storage chamber to a film processing device to develop the exposed film.

Abstract: This invention provides a photographic apparatus for successively photographing originals on a photographic film in a continuous web form and subsequently developing the thus exposed film. Said apparatus comprises a camera unit and a processor unit, wherein said camera unit comprising a film chamber for storing the photographic film exposed at an exposing position into a loop form, a feed path for feeding said film in said film chamber into said processor and means for advancing said film into said film chamber. The photographic apparatus of this invention is selectively usable either as a camera for photographing only or as a camera-processor for continuous photographing and development.

Abstract: In transferring a toner image carried on a toner image carrier onto a transfer medium, a uniform charge is imparted to the surface of the toner image carrier while a charge of the same polarity as the uniform charge is imparted to the surface of the transfer medium, whereafter a toner image is transferred from the surface of the toner image carrier to the surface of the transfer medium.
