Filed: 1982-04-26
Abstract: PURPOSE:To prevent the disturbance in the stage of transfer by providing a self-discharge type wire which is extended near the space where the surface of an image carrying body and a transfer material separate. CONSTITUTION:A transfer material is transferred thereon with the toner image on a photosensitive drum 1 by means of a transfer corona discharger 6, and is conveyed by the electrostatic attraction force that the material obtains there with a transfer drum 2. A grounded destaticizing wire 8 is extended by means of a supporting arm 9 having an insulation characteristic in the space of the position where the transfer material is separated. The separated transfer material is conveyed by the electrostatic attraction force which is increased by the grounded wire 8. The discharge in air is effected before the transfer material parts too far from the image carrying body right after the transfer and since the electric discharge between the transfer material and the destaticizing wire is accomplished uniformly, the disturbance of the transfer material is prevented. The good transferred image free from color deviation is obtained in the multiple color transfer wherein the transfer material is circulated repeatedly.

IPC: G11B15/087
Filed: 1984-04-09
Abstract: PURPOSE:To prevent abnormal increase of a load, by counting that the recording and reproducing processes of data are continuously executed on how many times of data blocks, and determining whether the processes are to be continuously performed or not by comparing the counted value with the threshold of a counting value issued by a command. CONSTITUTION:A control section 12 inputs a threshold setting signal 1 and threshold information 2 issued by a command from a host device in an OR circuit 13. A threshold counter circuit 14 stores the maximum permissible frequency of a streaming continuing number by means of the output of the circuit 13. A streaming counter circuit 15 advances stepwise by a streaming continuing signal 3 generated by the control section 12 itself and is reset by a streaming interrupting signal 4. A comparator circuit 16 compares the output of the circuits 14 and 15 with each other and, when they do not coincide with each other, outputs a streaming continuation enable signal 5. When they coincide with each other, the circuit 16 outputs a streaming continuation inhibiting signal 6. Therefore, the abnormal increase of a bus load can be prevented by interrupting the streaming operation at a prescribed times even if the streaming operation is to be made continuously for a long time.
