Abstract: A copying machine of the diazo type comprises a light exposure zone for exposing to light a diazo type photosensitive sheet superposed with an original, a development zone for developing the light exposed photosensitive sheet and a delivery mechanism for feeding the original and diazo type photosensitive sheet to the light exposure zone and forwarding the light exposed photosensitive sheet to the development zone. The light exposure zone includes a transparent cylinder capable of rotating while having a superposed assembly of the original and photosensitive sheet closely contacting the outer surface thereof and a heat-generating light source mounted in the interior of the transparent cylinder. The transparent cylinder has a fan for feeding cold air into the transparent cylinder from one end thereof and cooling the outer surface of the transparent cylinder substantially uniformly along the entire length thereof and a temperature-detecting mechanism thermoconductively contacting the outer surface of the transparent cylinder to detect the temperature of the outer surface. A temperature-controlling mechanism is provided to control the air feed rate of the fan in response to signals from the temperature detecting mechanism, to control the temperature of the outer surface of the transparent cylinder within a predetermined temperature range.

Abstract: 1282058 Electro-photographic developers MITA INDUSTRIAL CO Ltd 17 Dec 1969 [18 Dec 1968] 61581/69 Heading G2H A liquid developer comprises a dispersion in an insulating liquid of toner particles of an amine salt formed by the reaction of a dyestuff or dyestuff base possessing at least one amino group with an aliphatic carboxylic acid of at least eight carbon atoms, the developer having dissolved therein free aliphatic carboxylic acid in an amount of at least 3 mols per mol of the amine salt. It is stated that the dissolved free acid inhibits dissociation of the amine salt. Preferred dyes, acids and carrier liquids are listed. Reference has been directed by the Comptroller to Specification 1196749.

Abstract: An electrophotographic machine of such type that a roll-like electrophotographic copying paper is fed into each of treating zones disposed along a copying paper transfer passage by means of a feed reel and an optical system for forming an image corresponding to an image of an original to be copied is moved on a passage for the optical system in a machine frame to effect slit exposure; wherein the electrophotographic copying paper is cut in a size corresponding to an optional exposure length of the original, and the movement of the optical system for the exposure step is complete in correscpondence to the optional exposure length of the original and simultaneously the return movement of the optical system is initiated, whereby the copying operation can be accomplished promptly without bringing about a waste of electrophotocopying paper and a loss time during the copying operation.
Abstract translation: 一种电子照相机，其特征在于，将卷状电子照相复印纸通过馈送卷轴和用于形成与原稿的图像对应的图像的光学系统沿着复印纸传送通道设置的每个处理区域中进给 被复制在机架中的光学系统的通道上移动以实现狭缝曝光; 其中电子照相复印纸被切割成对应于原稿的任意曝光长度的尺寸，并且用于曝光步骤的光学系统的移动与原稿的可选曝光长度相对应地完成，并且同时使原稿的返回移动 启动光学系统，由此可以在复制操作期间快速实现复印操作，而不会造成电子复印纸的浪费和丢失时间。
