摘要： PURPOSE:To read out image information from a recording device and to generate a copy in case of obtaining the same copy afterwards, by recording simultaneously its image information in the recording device such as a magnetic disk, etc., in case of copying an original. CONSTITUTION:An image scanner 100 reads the image of an original placed on an original platen, and generates digital image information. An image printer 101 contains the image forming part of an electrostatic electrophotographic system, and forms an image by bringing a laser beam to scanning against a photosensitive drum. In case of copying the original, the digital image information generated by the image scanner 100 is sent to the image printer 101, printed by a laser printer, and also recorded simultaneously in a disk memory 102. In this way, in case of obtaining the same copy afterwards, the copy is obtained by the image information obtained from the disk memory 102.

摘要： PURPOSE:To attain edition even when a coordinate input device having a coordi nate input surface smaller than the maximum size of an original is used by executing precopying so that the original is set up to the size suitable for the coordinate input device and inputting the coordinates of an area to be erased, an area to be copied or a moving extent, etc., to the precopy. CONSTITUTION:When an original is set up on an original platen and an original cover is closed, the size of the original is automatically detected. When the original is set up in the longitudinal direction, the replacement of the original is instructed by displaying the replacement on a display part 221d. In case of setting up the original normally, copying magnification and form are automati cally selected so that a copy is suitable for the coordinate input device, and under said status, precopying is executed by depressing a print switch. The obtained copy is set up on the coordinate input device and editing operation is executed, so that the editing information is transmitted from the coordinate input device to the copying machine side.

摘要： PURPOSE:To easily switch a mode and to prevent a previously set-up image forming condition from being erased in error by forming a normal mode restoring means for restoring an interruption mode to the normal mode as it is an power non-saving mode when a key detecting means detects the depression of a power saving mode setting key during the interruption mode. CONSTITUTION:The power saving mode is set up by depressing the power saving mode setting key 1 in the power non-saving mode. On the other hand, the power saving mode is restored to the power non-saving mode by depressing the key 1 in the power saving mode. The interruption mode is set up by depressing an interruption mode setting key 2 in a normal mode other than the interruption mode and restored to the normal mode by depressing the key 2 in the interruption mode. Even if the key 1 is depressed in the interruption mode, the interruption mode is not directly switched to the power saving mode, but the interruption mode is once released and the normal mode is set up. Then, the normal mode is switched to the power saving mode by depressing the key 1 again.

摘要： PURPOSE:To prevent an image on one surface of a copying form from being seen through from the other surface side by controlling the quantity of exposure preferentially so that an image thinner than an image in normal copying operation is formed in both-surface copying operation. CONSTITUTION:A switch 44 has contacts S1 and S2 and its connection piece S3 is switched to the contact S2 when a both-surface copy mode is set or to the contact S1 when a one-surface copy mode is selected. The contact S1 of the switch 44 is connected to a fixed voltage 41 for one-surface copying together with the contact S1 of a switch 43 and the contact S2 is connected to a fixed voltage 42 for both-surface copying. The fixed voltage 42 for both-surface copying is set higher than the fixed voltage 41 for one-surface copying and image density is set a little bit thinner in both-surface copying than in one-surface copying. The fixed voltage 41 for one-surface copying is so set as to obtain optimum image density as usual.

摘要： PURPOSE:To facilitate supplementary copying operation and to perform automatic both side copying operation by holding a top-surface original on an original discharge path after the supplementary copying operation, feeding a reverse- surface original which is evacuated in an original inversion tray to an original platen again, and performing reverse-surface copying operation. CONSTITUTION:When the original of the 4th page is fed to the original platen 2 through an original feed path 38, 201 is carried from a paper feed part to a copying process part and copying operation is performed. The original 104 after a set number of sheets are copied is on stand by in the original discharge path 42 and the original 103 of the 3rd page is fed to the original platen 2 from an original tray 33. Forms 201 having an image of the original 104 copied on one side are guided from the original tray 21 to the copy processing part and an image of the original 103 is copied on reverse surfaces. The forms 201 are discharged to a sorter 4 and the originals 104 and 103 are discharged to above the original tray 33; and the original of the 2nd page is guided to the original platen 2 and its image is copied to forms 202. Consequently, supplementary copying operation for a defect in paper feeding is made extremely easy.

摘要： PURPOSE:To prevent a paper from being mixed with one-face copied paper by feeding a paper from an intermediate tray unless there is a paper in a subordinate intermediate tray during reverse-face copying operation and then feeding a paper from the subordinate intermediate tray when there is the paper in the subordinate intermediate tray. CONSTITUTION:The subordinate intermediate tray 81 is arranged rockingly around a both-face copying conveyance path 34 as a fulcrum and the end bottom face on the side of an inverting paper conveyance path 35 contacts a cam roller 82. When a paper is fed from the subordinate intermediate tray 81, the cam roller 82 rotates and the side end part of the inverting paper conveyance path 35 of the subordinate intermediate tray 81 moves up. The paper stacked in the subordinate intermediate tray 81 by this operation abuts on a subordinate intermediate tray part paper feed roller 84 and is fed toward the inverting paper conveyance path 35. A changeover claw 83 for one-face copied paper is arranged rockingly at part of the both-face copying conveyance path 34. Said changeover claw 83 is a one-face copied paper switching means and guides the one-face copied paper to an intermediate tray 22 or the subordinate intermediate tray 81.

摘要： PURPOSE:To remove a charge securely from the surface of a photosensitive body after a transfer process and to lower the electrostatic attractive force of waste toner by arranging a reflecting plate which distributes the light beam which provides the highest illuminance among light beams from a light source to the surface of the photosensitive body while slanting its optical axis slightly from a normal direction. CONSTITUTION:An electrostatic discharging device 22 for the photosensitive body has the elliptic reflecting plate 23 and incorporates the light 24. the reflecting plate 23 is arranged slantingly to a normal 41 to the surface of the photosensitive drum 1 and the light 40 is distributed to the surface of the photosensitive body at an angle thetaof incidence where the highest illuminance is obtained on the surface of the photosensitive body. Waste toner 50 remaining on the surface of the photosensitive drum 1 after the transfer process is stuck with electrostatic attractive force. The light from the electrostatic discharging device 22 is distributed to the surface of the photosensitive body at the angle theta of incidence to illuminate the contacting part between the waste toner 50 and the surface of the photosensitive drum 1. Consequently, a charge which generates the electrostatic attractive force making the waste toner 50 stick on the surface of the photosensitive drum 1 is removed securely.

摘要： PURPOSE:To make the diameter of a recording medium small, and to make the whole device small in size by placing a lamp for exposing uniformly the recording medium through a transfer material, in an area for transferring an image rotated on the recording medium, to the transfer material. CONSTITUTION:As soon as a transfer corona discharger 9 is operated, the overall length in the axial direction of a photosensitive body 5 is exposed uniformly by a lamp 20. The lamp 20 is provided on the back of a shield plate 9-1 of the corona discharger 9, and exposes the photosensitive body 5. In this case, other part than the part (the part which has been adhered tightly to the photosensitive body 5) corresponding to a transfer material is exposed by the lamp 20, therefore, adhesion of toner adhering to the photosensitive body 5 which is not transferred to the transfer material is weakened, a cleaning effect by a cleaning device 11 is raised, and the burden of cleaning is reduced. Also, the lamp 20 is provided on the back of the corona discharger 9 for transferring a toner image to the transfer material, therefore, the photosensitive body 5 can make a drum diameter small without being controlled by a placed position of the lamp 20.
