  • Patent number: 4090658
    Abstract: An egg packing container having in rows a number of egg-receiving hollows in a receptacle and its lid. A ventilating groove is provided in each row of the egg-receiving hollows or recesses of the receptacle and lid, the ventilating groove extending from one end to the other end of the container through bottom portions of the egg-receiving recesses to allow fresh air to enter the container, particularly the bottom portions of the respective egg-holding recesses. A closing flap is flexibly connected to the receptacle for holding the lid in the closed position without using additional fixing means.

  • Patent number: 4043661
    Abstract: An enlarger-printer wherein aperture cards, each mounting a microfilm, are fed one after another from a card hopper, moved in the direction in which the major sides of the cards are oriented and scanned in the direction in which the minor sides of the cards are oriented, so that imagewise exposing of a photosensitive member can be effected for each card to form an enlarged latent image of the film of each card on the photosensitive member, which latent image is then converted into a visible image. Before each card is scanned, the card is moved upwardly a distance corresponding to the margin between the image and the upper edge of the film to reduce the time required for effecting scanning. Switching between lenses of different magnifications, exposing slits of different widths and scanning speeds consistent with desired magnifications of the image can be effected simultaneously by simply actuating a lever.

  • Patent number: 3992089
    Abstract: The apparatus comprises a projection optical system and a copying system. The projection optical system can project an image of an original either onto a screen or to an exposing position of the copying system by switching between two positions. The copying system comprises a plurality of chargers providing different charging conditions in accordance with the types and sizes of copy sheets, by utilizing a change-over switch. A plurality of switches adapted for use with copy sheets of different lengths are arranged along the path of movement of a sheet of paper and, when the switch corresponding to the particular length of copy sheet desired is actuated, the movement of the sheet of paper is stopped, so that the central portion of the copy sheet can be brought into alignment with the optical axis for exposing at all times regardless of the difference in the length of copy sheets.
