Title: Image forming device
Inventor: KONO HISAAKI
IPC: G03G15/08
Filed: 1987-07-31
Abstract: PURPOSE:To always form an image at a fixed density and to prevent deterioration in image forming quality by comparing a developer concentration of a developing means with a reference concentration, judging the replenishing amount of a developer, driving a replenishing means and performing the replenishment of the developer according to the change in the consumption of the developer.

Namely, a toner concentration of a developing device 18 is compared with the reference value and the replenishing amount of toner corresponding to the difference is judged. The replenishment of the toner is performed according to the judged replenishing amount and the change in the consumption of the toner by driving the replenishing means. Therefore, when the image whose image density is high or the image whose density is low is copied, the most suitable toner amount can be replenished. Thus, printing can be always performed at the fixed density and the deterioration in the image forming quality is prevented.

Title: Tape deck
Inventor: TAKEHARA HIDEAKI
IPC: G11B15/675
Filed: 1990-07-17
Abstract: PURPOSE:To cope with an abnormal state without causing damage to a tape by ejecting the tape based on detecting results of the number of times of reversing the tape and the existence of looseness of the tape during a prescribed time. CONSTITUTION:The end of a tape is detected by a CPU 11 with an end detecting sensor 14, and when a prescribed time is passed, an end detecting counter is reset to perform a reverse operation. When the prescribed time is not passed yet, the end detecting counter is counted up to detect the end, and if looseness is generated, whether or not the looseness was in existence is decided by utilizing a fact that the next end detecting time becomes approximately double as long as an end detecting time with no looseness. If looseness was in existence, since the looseness has already disappeared, whether the detecting value is more than a prescribed value or not is decided by the counter, and if more than the prescribed value, the abnormality is decided an the ejecting operation is performed. By this method, the tape is not slackened, and the tape is ejected under the state of more than the prescribed value in the number of its reversing times during a given period of time, thus causing no damage to the tape.
