摘要： PURPOSE:To prevent a sheet paper from soiling and wrinkling by making a reverse roller follow the motion of a load when a load torque higher than the fixed value is applied, in case of a feeding apparatus having a mechanism for preventing double-feed. CONSTITUTION:When a sheet 11 is applied, a solenoid 10 operates to press a regular rotation roller 1 to a reverse roller 2. In the case that one sheet 11 is fed, it advances by the regular rotation roller 1. Because the driving force of this roller is large, a friction clutch 3 slips and the reverse roller 2 follows the motion of a sheet. In the case that two sheets are fed, they slips from each other, since the coefficient of friction between the sheets is small, and the upper sheet 11a advances and the lower sheet 11b is stopped by the reverse roller 2. In this way, any soiling and wrinkling of the sheet due to slippery contact with the reverse roller is prevented from generating.

摘要： PURPOSE:To completely eliminate the fog in a simple constitution, by providing a charger to give the electric charging to a recording matter to the same polarity as a toner before the developing process. CONSTITUTION:A charging corotron 10a is set opposite to a recording matter 2, and a metallic plate 15 containing an earthed end is provided inside the corotron 10a to form a charger. Then the surface opposite to the corotron 10a is electrically charged to the same polarity as a toner 13 of a developer. As a result, no electric insulation is required for a developing device 5, and furthermore an electric field which is necessary for the prescribed development can be formed just by using the corotron 10a and not using any bias power supply. Thus a so-called back fog can be completely eliminated.

摘要： PURPOSE:To facilitate an easy process for a continuous paper, by giving a gap between the both pressure rollers at the initial setting of the recording paper and when the paper jam is detected, and then giving a fine adjustment to the pressure distribution between the both rollers. CONSTITUTION:When the paper jam occurs, the recording paper 6 has lines. And the a certain engagment plate 53 is not restricted by the paper 6 any more to touch the electrode plate 56 and thus transmit the alarm signal. With this alarm signal, the eccentric cams 15 and 15' are turned in the same way as the initial setting of the paper to cause a gap between the pressure rollers 7 and 8. As a result, the jammed paper can be removed easily. The oblique shift of the paper 6 is detected by the oblique shift sensor 19 to deliver the signal. Then the eccentric cams 17 and 17' provided with a shift of 180 deg. given to the phase have turns according to the output signal in the same direction and by a fixed angle. As a result, arms 11 and 11' rock in the opposite directions to each other, and the spring force is controlled for the springs 16 and 16' to give a fine control to the pressure between the rollers 7 and 8. Thus the oblique shift of the recording paper is corrected easily.

摘要： PURPOSE:To prevent the formation of defective transfer images and white paper portions by specifying the transfer-in and out directions of transfer material. CONSTITUTION:A paper guide plate 11 comprising forming the paper guide 11a on the transfer-out side to hemi-cyclic form is vertically movably disposed to the upper part of a support body 1 and transfer material 4 is put thereon. With this arrangement, the transfer material 4 is turned by a conveying device 6 and the transfer material 4 is carried in from the tangential direction of the support body 1. The paper guide plate 1 is then lowered to be contacted to the support body 1 to transfer the toner images, etc. formed on the support body 1, after which the feed direction is reversed and when the transfer material is transferred out toward the transfer-in direction, the transfer material 4 is readily separated from the support body 1 owing to rising of the paper guide plate 11. At the same time, the point Ha of the transfer material 4 is simply moved perpendicularly to the surface of the support body 1 by the vertical movement of the paper guide plate 11 and therefore the velocity components in the tangential direction of the support body 1 are not generated.

摘要： PURPOSE:To operate smoothly and more automatically a fish body picture input apparatus by detecting automatically the clogging of fish to close a path and thereby prevent the succeeding fish from being transferred therein. CONSTITUTION:When a weight roller is choked with fish, the output of a light receiving sensor is left as L, and electric pulse does not enter the input terminal B of a counting circuit 82 so that subtraction by the counting of said circuit 82 is not carried out. On the other hand, every time a spike drum is rotated by one revolution, fish is sent into a tray while electric pulses are applied from a rotary encoder to the terminal A of the circuit 82 and adding is carried out by the counter so that the accumulated value in the counter exceeds value N0 preset in the circuit 82. Thus the output terminal C of the circuit 82 is held at 1, the output of the light receiving sensor is left as L and the input terminal I and output terminal J of the circuit 85 become L and 1 so that air valves 51, 53 permit a shutter to close a fish path with an air cylinder.

摘要： PURPOSE:To obtain a cut paper with less position shift in printing and an less error in cutting width by obtaining a cutting signal according to the rotation of a fixing roller which is closest to a cutter, and correcting recording paper during transfer fixation, page by page. CONSTITUTION:A turning-angle encoder 90 for a fixing roller 9 generates a pulse signal (e) and a latent image forming device 3 inputs a page end trigger singal (f) to a flip-flop circuit 80 to output a set signal (g). Simultaneously, a passage 1' between conveyance rollers 2 and fixing rollers 9 is controlled by a buffer roller arm 7 which oscillates according to the expansion and contraction of the passage. A preset-number correcting circuit 70 performs automatic correction to input a corrected signal to a counting circuit 40, and a count end signal is fed back to the cicuit 80, which resets a set signal (g) to decide on signal length; and a signal (h) from AND50 is supplied to the circuit 40, which outputs a cutting signal (d) to a cutting driving part 10.
