Title: System for detecting remaining quantity of developer
Inventor: IGAWA HARUO
IPC: G03G15/08
Filed: 1986-10-09
Abstract: PURPOSE:To prevent wrong output of a 'no developer' warning when the stirring of a developer is stopped, by causing the 'no developer' warning to be outputted when a driving signal indicating that the developing agent is stirred and a remaining quantity signal from a capacity sensor indicating that the no developer is left are simultaneously inputted. CONSTITUTION:An alarm circuit 6 inputs the remaining quantity detecting signal 10 of a capacity sensor 4 and drive signal 11 of a driving circuit 7 and makes AND calculation on the signals 10 and 11. When the output of the AND calculation maintains a high level for more than Tsec, the alarm circuit 6 outputs a 'no developer' warning to the outside so that shortage of the developer 2 can be informed and the agent 2 can be supplied. Namely, the alarm circuit 6 accept the remaining quantity detecting signal 10 indicating that no developer is left from the capacity sensor 4 and outputs the 'no developer' warning to the outside, only when the driving circuit 7 outputs the drive signal 11 and drives a motor 5 and stirring vanes 3 stir the developer 2. Therefore, wrong output of the 'no developer' warning when the stirring of the developer is stopped can be prevented.

Filed: 1983-12-20
Abstract: PURPOSE:To obtain fixed stylus force by detecting the sensitivity of a cantilever every time stylus force is applied, estimating the magnitude of magnetic field necessary to obtain prescribed stylus force, and controlling the amount of current of a stylus force coil so as to obtain the estimated magnitude of magnetic field. CONSTITUTION:A low pass filter 15 connected to the output of a D-A converter 14 consists of an integrating circuit. DC voltage corresponding to a digital numerical value is applied to transistors 1, 5 by count up down command signals c, d, and a magnetic field corresponding to the DC voltage value is applied to a magnet 9. An arithmetic unit 18 outputs a count up command signal (c) when stylus force is to be increased, and outputs a count down signal (d) when decreasing stylus force. Accordingly, when the stylus is at a point (a), the count down command signal (d) is inputted to make the value of an internal digital signal zero. When the stylus 11 is brought to a point (b) by the count up command signal (c), a signal (f) goes to high level, and a value to be outputted next is calculated from the value of the count up command signal (c) and stylus force coefficient data (g) corresponding to the value, and outputted. Accordingly, practically usable nearly accurate stylus force value can be obtained even when many conditions are superposed.
