IPC: G03G15/10
Filed: 1990-03-06
Abstract: PURPOSE:To reduce maintenance and inspection and to detect the concentration of developer with high detecting accuracy with a comparatively simple device by detecting a residual potential on a developed electrostatic recording paper and obtaining the concentration of the developer. CONSTITUTION:The residual potential of a developed toner concentration detection mark is detected by a potential sensor 24. The output of the sensor 24 is amplified in an amplifier part 27, rectified in a rectification circuit 28 and smoothed in a smooth circuit 29, then it is digitized in an A/D converter 30. A comparison circuit 31 compares the digitized voltage value with a reference value, and outputs a replenishment signal when the voltage value exceeds the reference value, and an electromagnetic value control circuit 32 opens an electromagnetic valve 11 for a specified time so that concentrated toner 10 may be allowed to flow in a developer tank 4 from a concentrated toner container 9 to hold the concentration of the developer 5 in a specified range. Thus, concentration measuring accuracy is considerably improved, and it is almost unnecessary to perform the maintenance and inspection work because only the residual potential of the toner concentration detection mark part on the electrostatic recording paper 2 is measured.

Title: Magnetic inductor detecting method and the like
Inventor: IKOMA AKIRA
IPC: G03G15/00
Filed: 1993-03-16
Abstract: PURPOSE:To accurately detect a magnetic inductor from an electric amount generated due to an electromotive force of a coil by energizing a coil to generate a magnetic field between the coil and a detecting place, and then stopping the energization of the coil. CONSTITUTION:When a control signal to be input from a terminal 28 to a base of a transistor 25 becomes a low level, the transistor 25 turns on, and a current flows from a power source 26 to a coil 21. Thus, a magnetic field is generated between the coil 21 and a detecting place 22. When the signal from the terminal 28 is set to a high level as a current flowing to the coil 21 becomes stable, the transistor 25 is interrupted, and the energization of the coil 21 is stopped. Therefore, the current of the coil 21 is gradually decreased. The decrease in the current becomes slow, the larger an inductance of the coil 21 is. When a magnetic inductor 23 is disposed at the detecting place, the inductance becomes larger than that when the inductor 23 is not disposed, and an electromotive force of the coil 21 is also increased. Accordingly, presence/absence of the inductor 23 can be detected from a length of a time in which a diode 27 is conducted by the electromotive force of the coil 21.
