Title:
SURFACE TEMPERATURE CONTROL UNIT OF MOVING OBJECT
Document Type and Number:
Japanese Patent JPS5578309
Kind Code:
A
Abstract:
PURPOSE:To keep the temperature of the rotary cylinder of a copying machine, etc., at a constant temperature for stop as well as movement, by performing correction corresponding to output difference of a temperature detection element between stop and movement of a moving object. CONSTITUTION:The temperature detection signal from temperature detecting thermistor TH brought into contact with a moving object controls oscillation of programmable uni-junction transistor PUT through differential amplifier IC. This oscillation output controls heater H, which heats the moving object, through pulse transformer PT and triode AC switch TRC. The detection output of thermistor TH brought into contact with the moving object is different by contact conditions according to stop or operating of the moving object even in case of a constant moving object temperature. In this invention, this difference is corrected by connecting resistance R10, which is connected to switch 1a2 interlocking with start switch 1a1 of moving object driving motor M, in parallel to thermistor TH.
