摘要： PURPOSE: To easily form a prescribed image on an OHP film by mounting an OHP film magazine to the body of an image forming device and driving the OHP film in the magazine in one direction or the opposite direction thereof by a driving means.
CONSTITUTION: A conveying unit 15 is first removed from the body of a copying machine and in turn, the OHP film magazine 21 is mounted in the stage of recording the image on the OHP film. An upper opening 29 and a lower recess 23 are formed to a body case 22 of the magazine 21. The OHP film 25 is sandwiched between a photosensitive body 5 and a transfer charger 12 and a fixing device 19 is positioned to face the film 25 via the opening 29 when the magazine is held mounted. The visible image on the photosensitive body 5 is transferred onto the film 25 by a transfer charger 12 while the film 25 is fed toward the left. The film is once moved toward the right after the end of fixing by the fixing device 19 so that the formation of a large margin with the next image is obviated, then the next image is formed on the film 25.

摘要： PURPOSE:To obtain a copy having no focus shift by correcting a difference of an optical path length between an image surface and the surface of a photosensitive body of the time for copying an original and the time for copying a liquid crystal display image, by a movement of an optical element of an exposing optical system. CONSTITUTION:A titled device can be moved as one body from a position of the time for copying an original, shown by a full line in the optical axis direction of a lens 25, to a position of 23' and 24', which is separated by a distance (a) and shown by a broken line. By setting the distance (a) to 1/2 of an optical path length difference DELTAS, the optical path length to the lens 25 is lengthened by 2a=DELTAS. According, when copying an original, the second and the third mirrors 23, 24 are moved to a position of 23' and 24', and by moving the mirror at a prescribed scan speed from this state, the optical path length difference is corrected exactly, and a focus shift caused by copying of a liquid crystal display image is prevented.

摘要： PURPOSE:To display an easily observable image by executing a control so that an erect image and an inverted image are displayed on the front, when a contact glass is in a vertical position, and its surface, when said glass is in a horizontal direction, respectively, with regard to an image displayed on a liquid crystal display. CONSTITUTION:In case a liquid crystal display 1 has been set to a horizontal position in order to print an image signal from an external device 20, an image displayed on the liquid crystal display 1 by an external signal is controlled so as to become an inverted image by seeing it from above. Accordingly, it becomes an erect image, when it is seen from the lower side, and when it is illuminated by an exposing lamp, made to form an image on a photosensitive body by executing an exposure scan, transferred and a print is made, an image on the print becomes an erect image. On the other hand, in case copying is executed from an original, when the liquid crystal display 1 is set to a non- operation, the liquid crystal display has a light transmission property being uniform on the whole surface, therefore, it can be used as a contact glass, and a copy can be made in the same way as an ordinary copying machine.
摘要翻译：目的：为了通过执行控制来显示容易观察的图像，使得在前方显示直立图像和反转图像，当接触玻璃处于垂直位置时，以及其表面，当所述玻璃在水平方向上时，分别关于显示在液晶显示器上的图像。构成：在将液晶显示器1设定为水平位置以便从外部设备20打印图像信号的情况下，控制通过外部信号在液晶显示器1上显示的图像，使其变为反转从上面看它的形象。因此，当从下侧观察时，当从曝光灯照亮时，通过执行曝光扫描在感光体上形成图像，转印并进行打印，从而成为直立的图像。打印上的图像变成直立的图像。另一方面，在从原稿执行复印的情况下，当将液晶显示器1设定为非操作时，液晶显示器的整个表面的透光性均匀，因此可以使用作为接触玻璃，并且可以以与普通复印机相同的方式制作复印件。

摘要： PURPOSE:To obtain a distinct image by synchronizing a liquid crystal display driving means and an original scanner driving means so that a range illuminated by a light source of an original scanner is driven to display selectively, when a print of an image which has been brought to a liquid crystal display has been selected by a switching means. CONSTITUTION:In case when an image display onto a liquid crystal display 1 by an external signal has been selected by a selecting switch, as for the liquid crystal display 1, an image is displayed on the whole display area. In case a print of a display image has been selected, first of all, the right and left conversion of the image display is executed. At the time of a display, in case when 'ABC' as seen from above has been displayed onto the liquid crystal display as shown in a figure (a), it becomes an inverted image in case of seeing it from the lower face illuminated by an illuminating lamp of a scanner, and when copying is executed in this state, an inverted image is printed to a print to be transferred. Accordingly, in case a print is made by copying an image on the liquid crystal display, since it becomes an inverted image by seeing it from above as shown in a figure (b), the right and left conversion of the image is required. Subsequently, a copy control is started.
