    • 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.

    • 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.
    • 本说明书公开了一种用于在电影的长镜头上连续拍摄原稿的装置。 各种尺寸的原件,如支票,证书,凭证等都在电影上拍照。 当在非照相胶片上拍摄各种尺寸的原稿时,显示在未照相胶片上可以拍摄原稿的原稿。 在未照相胶片上可拍摄的原稿的数量可以为每个原稿的大小而知道,并且也可以被称为具有迄今为止被拍摄的平均尺寸的原稿的数量或具有最小或最大尺寸的原稿的数量。 此外,在拍摄装置中,拍摄胶片暂时存储在存储部分中,然后被馈送到显影部分,显示可以在要存储在存储部分中的胶片上拍摄多少张原稿。
