摘要： A thermal fixing device for a xerographic reproducing apparatus includes a thin planar resistance heating element having a low thermal mass and a high coefficient of thermal expansion. The heating element is supported in such manner that one end thereof is free to move linearly under thermal expansion to activate a heater displacement detector comprising a pivotally mounted lever arm having a right angle configuration. One end of the lever arm is received in an opening in the heating element and the other end form a contact of a normally open switch which is adapted to be closed by pivoting of the arm due to expansion of the heating element. Closure of the switch activates a power controller to interrupt the power supply to the heating element.

摘要： In a caser where a first current is supplied to a first heater, a controller gradually increases the first current in a first period, supplies the first current based on a first duty cycle in a second period, and gradually reduces the first current to stop supplying the first current in a third period. In a case where a second current is supplied to a second heater, the controller gradually increases the second current in a fourth period, supply the second current based on a second duty cycle in a fifth period, and gradually reduces the second current to stop supplying the second current in a sixth period. The controller controls the supply of the second current such that part of the fourth period overlaps with the third period.

摘要： A heater lamp control apparatus and method of detecting an input AC voltage and providing a pulse signal corresponding thereto, includes an AC voltage phase detection unit to detect a phase of the inputted AC voltage when a magnitude of the inputted AC voltage is over a predetermined level. The heater lamp control apparatus also includes a pulse signal generation unit to generate a pulse reference signal based on a result of the detection, a pulse delay signal that is phase-delayed, and a heater lamp control pulse signal based on a result of the comparison of the magnitudes of the pulse reference signal and the pulse delay signal. The heater lamp control pulse signal includes a control unit to control a drive-timing of the heater lamp based on the heater lamp control pulse signal. Thus, the heater lamp control apparatus minimizes a flickering phenomenon as well as an amount of electric power consumed in a heater lamp.
