Abstract: A copying machine comprising an original detecting member upstream of an original-exposing section of an original transfer passageway, a synchronizing feed roller immediately upstream of the original detecting member, and a sensitive paper detecting member upstream of a sensitive paper-exposing section of a sensitive paper transfer passageway. In order to cause both an original and a sensitive paper to reach the exposing sections synchronously. When the original has reached the original detecting member, the rotation of the synchronizing roller is stopped, and at the same time, the supply of a continuous sheet of sensitive paper is begun, and when the leading edge of the sensitive paper has reached the sensitive paper detecting member, the rotation of the synchronizing roller is resumed. The sensitive paper is cut to a predetermined size by the action of a timer.

Abstract: 1493280 Developing electrostatic images MITA INDUSTRIAL CO Ltd 31 July 1975 [1 Aug 1974] 32102/75 Heading G2H A developing apparatus for electrostatic latent images includes a member which carries a layer of one component powder developer into rolling contact with a body bearing the images, so positioned and dimensioned that an accumulation of developer forms ahead of the contact of member and body and the accumulation is internally mixed. For example, a magnetic brush roller may be caused to apply a developer which is both magnetically and electrostatically susceptible to images, and the developer may be internally mixed by passage through a wire mesh. Alternatively developer may be applied by action of a rotating magnetic body within a stationary or counter rotating sleeve, so that the developer somersaults into contact with the images to be developed.

Abstract: 1357629 Electrostatic printing MITA INDUSTRIAL CO Ltd 29 Dec 1971 [29 Dec 1970] 60530/71 Heading G2H [Also in Division B6] Electrostatic printing is carried out by forming an electrostatic image on a surface 4, suitably by electro-photographic means, and developing it with a toner 6 whose particles have a charge of the same polarity as that of the latent image, then contacting the surface 4 with an imagereceiving member 7 with electrical properties so chosen as to be able to receive the toner image without dissipation or disturbance of the latent image, which can be redeveloped for making of a second toner image. A charged insulating surface 4 may be exposed to a light image, and simultaneously subjected to a corona discharge which either is A.C. or of the opposite polarity to the charge previously given to the surface at 13. Then the entire surface is exposed to light 16, and a latent image is formed.
