摘要： The apparatus includes a vertically movable paper tray that descends to its lowered condition when a copier door is opened for resupply of copy sheets, a switch for detecting the fully raised sheet feeding condition of the tray, and a photosensor for detecting the presence of paper on the tray as the tray is raised toward its fully raised condition. A copier operation enabling signal is generated in response to the position of the door and the photosensor output, with a suitable time delay to prevent copying until the tray has attained its fully raised condition following detection of the presence of paper by the photosensor.

摘要： An image recording apparatus wherein image information is developed by converting the image information into an optical signal and by writing the image information on a drum-shaped image retainer with the converted optical signal to provide latent images and by developing the latent images, which are then recorded. A first writing timing is set in a first writing direction with respect to the image retainer and a second writing timing is set in a second writing direction with respect to the image retainer and the number of rotations with respect to the image retainer is calculated in accordance with the settings of the writing timings. The image information is overwritten by a number of times corresponding to the number of rotations to provide a plurality of images which may be entirely or partially or not superposed on one another.
