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.

Recording apparatus

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.

Web roll amount detecting apparatus

A photographic apparatus for photographing originals in succession onto a photographic film of a continuous web form and then processing the thus exposed film. The apparatus is provided with a storage chamber located between the photographing station and the processing station for temporarily storing the film advanced from the photographing station, a feeder for feeding the film from the storage chamber to the processing station and a switch for actuating the feeder to feed the film from the storage chamber to the processing station. There are further provided a photographing controller adapted to prohibit the operation of the photographing device when a determined amount of the film is stored in the storage chamber and enable the photographing operation in response to the actuation of said switch, and a cutter for cutting the exposed film.

Photographic apparatus

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.

Photographing apparatus

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.
