摘要： PURPOSE: To improve an image editing function and operability by copying the overlapped part of the previously inputted original and erasing the over lapped part of the second original, when image regions are overlapped. CONSTITUTION: The first original is illuminated by an exposure optical device for illuminating 8 including a light source 2, mirrors 3-6 and a lens 7, to form an image on a photoreceptor 9 by an exposure. In an original replacing device 1, the first original is taken out and the second original is set in a fixed position. Then, a transfer is performed on the surface having the image of the first original of a transfer paper 14 fed to a transfer position. When the overlapped part appears from a viewpoint of the arrangement of the transfer paper 14 to which the image regions of the first and second originals are copied, the overlapped part of the previously inputted first original is copied and the overlapped part of the second original is erased by an erasing unit provided for erasing in the horizontal direction of an electrostatic latent image in a coping process.

摘要： PURPOSE:To mount a back tape in a simple, small-sized lowcost structure. CONSTITUTION:A tape T is so previously wound in a roll that an adhesive surface is opposed to a sheet bundle P and contained in a tape cartridge 55. A tape mounting unit is so mounted at a mounting position that a lateral direction of the tape T is protruded from a leading end of the bundle P in an advancing direction, and when the bundle P is stopped at a mounting position, a free end of the tape P is pressed by the rotation by a solenoid. When the cartridge 55 is moved in a lateral direction of the bundle P while maintaining this state, the tape T is mounted in a lateral direction in a state of protrusion from the end of the bundle P, and when the tape T is mounted in a lateral direction of the bundle P, the cartridge 55 is stopped and rotated to cut the tape T.

摘要： PURPOSE:To clear the sorting of resultant substance in a device provided with a binding machine as a postprocessor. CONSTITUTION:The binding device 40 which binds the bundle of a recording paper 9 by a belt-like substance is provided at an ejection part which ejects the paper 9 where an image is formed to the outside of a machine. Besides, the binding device 40 is provided with a loop forming part 34 which forms the loop of the belt-like substance in the ejecting path of the paper 9, a stack part 19 which stacks the paper 9 in the belt-like loop and a stack position change means 15 which relatively changes the position of the bundle of the stacked paper 9 in a front and back direction with respect to a loop position, for example. By varying the binding position by driving the change means 15 by a binding control means every prescribed binding unit, for example, every time when one copy is finined, the binding result whose sorting is cleared and whose state is different is obtained.

摘要： PURPOSE:To draw out a belt material with an optimum length and prevent recording paper from choking due to drawn-out tape when recording is still left paper on a tray by detecting whether the recording paper is on a placing base or not and feeding the belt member only when the paper does not exist and turning around. CONSTITUTION:A tape-holding claw 29 is used as a turning means around periphery to circulate a belt member 23. After specified sheets of recording paper 32 are fed on a placing base 35, a tray for instance, a driving roller 25 is driven reversely counterclockwise to pull back the tape 23 to bundle the periphery of the recording paper 32. And a detecting hole 36 is provided on a mounting base 35 for the recording paper 32 to detect whether the taking out process of the recording paper 32 after bundling is completed or not. And the paper detector like an optical sensor 37 or like having alight projector and a light receiver is provided. When recording paper already recorded is detected, removal of paper is indicated and directed. When paper does not exsist, the tape is wound off (feeding out) and the recording paper wound off after recorded is bundled.

摘要： PURPOSE:To correctly perform prescribed operations by displaying various working contents when an old cartridge is removed to replace it with a new one. CONSTITUTION:As toner is replenished, the toner quantity is gradually reduced in a toner replenishment chamber 21. When the residual toner in the replenishment chamber 21 is below a fixed amount, a toner exhaustion detecting sensor 22 being a toner lack detecting sensor provided near the bottom of the toner replenishment chamber 21 detects it and outputs a signal. Together with the detection of toner exhaustion, a display device provided on the forward upper part of a copying machine main body 100 displays toner replenishment instruction. According to the contents displayed on the display device, an operator removes the old toner cartridge, sets a new one, performs prescribed operations, and surely replenishes toner to a developing device.

摘要： PURPOSE:To prevent toner from being used wastefully by allowing an eraser to destaticize a latent image before development and after an electrostatic latent image is read out by a potential sensor. CONSTITUTION:The potential sensor 12 and the eraser 13 are arranged between an exposing part 4 and a developing part 16. To indicate more precisely, the potential sensor 12 is arranged in the upstream of a photosensitive body belt 10 in its rotating direction, and the eraser 13 is arranged downstream thereof. After a pattern is formed as an electrostatic latent image on the photosensitive body belt 10, its potential is detected, and then the electrostatic latent image of the pattern is destaticized by the eraser 13. The pattern part is not developed. The wasteful consumption of toner, and deterioration in a cleaning means can be prevented.
