IPC: G03G15/04
Filed: 1990-11-30
Abstract: PURPOSE:To obtain a prescribed gradation characteristic by changing gradation correcting data in accordance with a detected density when the detected density exceeds a prescribed density range. CONSTITUTION:The grid potential VG of an electrifying charger 43 and the developing bias potential VB of developing units 45a-45d are changed based on the toner sticking quantity of a reference toner image measured by an AIDC sensor 210 to carry out the adjustment of an image reproducing density. At such a time, in the combination of the maximum values of the adjustment possibility ranges of the grid potential VG and the developing bias potential VB, and in the combination of the minimum values of the adjustment possibility ranges of the grid potential VG and the developing bias potential VB, when a density corresponding to the sticking quantity of the reference toner image exceeds the range of the density covered by a density controller, a gamma-correcting table is changed so as to obtain the prescribed gradation characteristics in corresponding to a density detecting level LBA measured from the toner sticking quantity. Thus, the prescribed gradation characteristics are obtained.

Filed: 1990-11-30
Abstract: PURPOSE:To make eject of an information recording medium possible only when data are correctly written in an information recording medium by allowing the discharge of the information recording medium only at the time of detecting the shift of a table to a completely closed state. CONSTITUTION:When a partition closing declaration is generated at the time of ending the use of an optical disk 121, a file management mechanism 113 writes all the data of a partition concerned stored in a disk cache 114 in the disk 121. After closing the state of the partition concerned in an open table 116, a disk exchange management mechanism 115 inspects whether the states of all partitions in the table 116 have been closed or not. In the closed state of all the partitions, the mechanism 11 is allowed to discharge the disk 121. Consequently the optical disk 121 can be ejected only when data are correctly written in the disk 121 to be an information recording medium.
