摘要： PURPOSE:To reduce the extent of load due to paper taction as well as to make removal of a jammed sheet of paper ever so easy, by installing a guide plate guiding paper into a horizontal register roller, while moving it sidewise together with the horizontal register roller, and rotating the guide plate in addition. CONSTITUTION:The paper fed in a direction toward an arrow A is detected just before a horizontal register roller 47, while a feed roller 46 comes to a stop after the elapse of the specified time long. Since the roller 47 stops at this time, there is formed a loop between the roller 47 and the feed roller 46. Next, when a solenoid valve 55 is turned on, a lower roller 47b gets starting and simultaneously a spring clutch 53 comes on, rotating a cam 51. Together with a block 52, this cam 51 makes the roller 47 and a guide plate 150 move in a C direction. Each position after movement is detected by a sensor 60 whereby sidewise movement is stopped, and the roller 47 keeps up its rotation till paper comes off. And, when the guide plate 150 is rotated clockwise, it uplifts an upper roller 47a, and since a clearance is formable between both upper and lower rollers, removal of the jammed paper also is made ever so easy.

摘要： PROBLEM TO BE SOLVED: To provide a silent image forming device where working sound volume is low. SOLUTION: This image forming device is controlled so that an original G is successively carried to a specified reading position on a platen glass 1 by an original carrying means 103 and the image of every original G is read in a standby state before an image forming part 105 becomes an image forming feasible state, and the working sound of the carrying means 103 is reduced in the case of reading the original image in the standby state.

摘要： PROBLEM TO BE SOLVED: To heat even a part separate from a heating body to some temperature not so high as that at a fixing part, to hardly influence temperature and humidity at a transfer part by ambient temperature and humidity, to carry out good-quality transfer and to obtain a good-quality image by extending and arranging film to be opposed to an image carrier and utilizing it as a transfer belt. SOLUTION: A corona discharger 61a for imparting charge having an opposite polarity to the electrification polarity of toner to the surface of transfer material carried from a carrying path is disposed just on the downstream side of a pair of resist rollers 82. A corona discharger 61b for imparting the charge having the same polarity as the electrification polarity of the toner is disposed on the upstream side of the transfer part inside the film 62. Then, a linear heating body 94 is disposed at a position on a nearly opposite side to a transfer electrifier 61c inside the film 62, and a pressure roller 95 excellent in releasing property is arranged at a position opposed to the heating body 94 so as to press-contact with the body 94. Thus, the transfer material advances to the transfer part in a state where it is brought into contact with the film 62 similarly to the transfer belt.

摘要： PROBLEM TO BE SOLVED: To provide a document feeding device capable of positively separating a tip-curled document. SOLUTION: A plurality of transfer belts 26 for sucking and carrying documents are placed in parallel above a document tray for stacking the documents. Ribs 203 in which their lower end parts are positioned at the lower side rather than the sucking surfaces of the transfer belts 260 are provided between each transfer belt 260. Suction force afforded by a blower 253 sucks the uppermost document G3 of the documents stacked on the document tray to the transfer belts 260. Part of the document G3 is then hits the ribs 203 to be deformed (corrugated). Such the deformation (corrugation) is positively applied to the tip-curled document. The corrugated document G3 is liable to being separated from the document G4 located immediately below the document G3. The spaced gap easily invites original-separating air injected from nozzles 221.

摘要： PURPOSE: To make a screw low price, to enable abutting a cleaning pad to a wire at plural positions and to perform satisfactory cleanings for a long period by providing a bearing stopping at an intermediate position by being separated from a transferring piece after being connected to the transferring piece till the intermediate position in the moving stage of the transferring piece. CONSTITUTION: In a frame body 1 arranged adjacently to an electrifier, a means connected to the cleaning member of the electrifier is projectingly provided in the longitudinal direction and slits 1a guiding a transferring piece 3 are provided and a screw 2 is fitted along the slits. The transferring piece 3 is screwedly engaged with the screw 2 to be moved in the left and right directions shown in figure by the rotation of the screw 2. Moreover, a stopper 5 is arranged in the frame body 1 at a position being near the nearly center of the screw 2 and a bearing 4 loosely engaged with the screw 2 in between the stopper 5 and the one edge part of the screw 2 and guided by the slits 1a is arranged. Then, the width of the bearing 4 is made so that the bearing is abutted to the stopper 5 to be forcibly stopped at this position.

摘要： PURPOSE: To surely separate the lowest paper sheet with an air flow of relatively low pressure and small flow rate blown from the tip side at the time of feeding large size sheets in the lengthwise direction, by constituting a sheet rear end side loading part to be turnable in the vertical direction around a pivot. CONSTITUTION: A double-side unit 19 is provided with an intermediate tray 3 consisting of front and rear trays 3A, 3B, and on these top surfaces, the front and rear sides of a large-size paper sheet S fed in the longitudinal direction are placed. In the center of the front tray 3A, a sheet conveyance part 112 is disposed, and on the rear tray 3B, the rear end regulating plate 4 of the sheet S and respective side regulating plates 9a, 9b are disposed. The rear tray 3B is disposed so as to rotate in the vertical direction around the shaft 20, and is rotated downwards by driving a motor connected to the shaft 20. When the sheets S of prescribed quantity are loaded on a sheet conveyance means 3, a sheet rear end side loading part 3B is set in a condition inclined by a prescribed angle.

摘要： PURPOSE:To prevent any passing mark of a paper refeeding roller from being left behind on a sheet to be refed out of an intermediate tray of an image former. CONSTITUTION:A sheet 1 imaged on a first surface is jogged by a stopper plate 18 and loaded on an intermediate tray 26 and then it is refed by a paper refeeding roller 19. At this time, an elastic member 57 to be deformed by a smaller load than the self-weight of this stopper plate 18 is installed in a position corresponding to this roller 19 of the stopper plate 18. With this constitution, any refeeding trace (roller passing marks) by the roller 19 as seen in the example heretofore is thus prevented from occurring.

摘要： PURPOSE:To control the drive of a heating means and simultaneously, to display time information on drive on a control panel by inputting the actuation starting time of the heating means for preventing dew condensation through the key operation of the control panel. CONSTITUTION:When a user suspends a copying machine in a closing time, etc., the user inputs a specified time t2 from the next opening time, that is, a time lapsing from the present time to that time on the control panel, before a main switch is turned off, so that the dew condensation occurs inside the copying machine, a heating device is turned on before a minimum of time or above required for eliminating the dew condensation after the heating device is turned on. Thus, when a time t1 is set on a timer and the time of the control of the timer is up, an MPU receives a signal from the timer and generates a control signal for supplying electric power to the heating device again. Consequently, the user can obtain the copying machine for a normal image in a short waiting time just after working is started and evade the futile consumption of the electric power for heating.
