The present invention relates to a power control device for a copying machine that is capable of supplying the maximum allowable power to a heat fixing device in view of the power capacity of a power source.
複写機においては、電源投入後の使用者の待ち時間をな
るべく短かくするために、そのウオーミングアツプ時間
を短縮することが望まれる。In a copying machine, it is desirable to shorten its warming-up time in order to reduce the waiting time of a user as much as possible after the power is turned on.
ウオーミングアツプ時間は、良く知られているように、
主として、電源投入時から、熱定着装置内の定着器の温

ウオーミングアツプ時間の短縮のためには、電源投入後
に、前記定着器を加熱する定着ヒータになるべく多くの
電力を供給してやることが必要である。As is well known, the warming-up time is
It is mainly determined by the time from when the power is turned on until the temperature of the fixing device in the thermal fixing device reaches a specified value. therefore,
In order to shorten the warming-up time, it is necessary to supply as much power as possible to the fixing heater that heats the fixing device after the power is turned on.

0v, 15A - i.e. 1500VA.

で、従来は、これらの消費電力を考慮しても前記許容電
力値を超えないように、定着ヒータの最大消費電力（す
なわち、定格）が設定さねでいた。Copying machines have parts that consume power in addition to the fixing heater, such as various electric motors and exposure lamps. However, the maximum power consumption (i.e., the rating) of the fusing heater has not been set.

限されてしまい、ウオーミングアツプ時間の短縮が難し
いという欠点があった。Therefore, even though other electrical components are not yet in operation during warming up after the power is turned on, and therefore the power supply has sufficient power capacity, the power supplied to the fusing heater is limited to the fusing heater. There is a drawback that it is difficult to shorten the warming-up time because it is limited by the rating of the heater.

的とするものである。The present invention overcomes some of the above-mentioned drawbacks and makes it possible to supply the maximum power allowed by the power capacity of the source to the fuser heater, especially during the warming amplifier of a copying machine, thereby minimizing the warming amplifier time. It is an object of the present invention to provide a power-operated kettle device for erishiso, which can be shortened in size.

るようにしている。In order to achieve the above purpose, in the present invention, the rated power consumption of the fusing heater is set sufficiently large, so that the sum of the power consumption of other electrical parts and that of the fusing heater is as much as possible within the allowable power supply. The power supplied to the fixing heater is controlled so that it is equal to the power supply, that is, the maximum allowable power is supplied to the fixing heater in view of the power capacity of the power source.
以下に、図面を参照して本発明の詳細な説明するＯ 第１図は本発明の一実施例のブロック図である。Hereinafter, a detailed explanation of the present invention will be given with reference to the drawings. FIG. 1 is a block diagram of one embodiment of the present invention.

ある。In the figure, l is an AC power supply, 2 is a power switch, 3 is a current detector, 4 is a fixing heater, 5 is a triac connected in series with the fixing heater 4, 6 is an electric component other than the heat fixing device, and 7 is an electric component. A conduction angle control circuit for the triac 5, 8 a comparator, 9 a fuser temperature detector (thermistor),
10 is an operational amplifier, 11A, IIB is a rectifier circuit, 1
3 is an operating power transformer, and 14 is a (voltage) stabilizing circuit.
いま、電源スィッチ２を閉成すると、定着ヒータ４およ

ータによる熱定着器（図示せず）の加熱が開始される。Now, when the power switch 2 is closed, a power supply voltage is applied to the fixing heater 4 and other electrical components 6, and the fixing heater starts heating a thermal fixing device (not shown).
この時、定着ヒータ４および熱定着器は規定の湯度以下
であるため、ウオーミングアツプ期間となり、コピーを
取る事は出来ない。At this time, since the hot water temperature of the fixing heater 4 and the heat fixing device is below the specified temperature, the temperature is in a warming-up period and copying cannot be made.
しだがって、熱定着器以外の電気部品（各種電動機や露
光ランプなど）は作動しておらず、その消費電力は極め
て少なく通常は、数１．ＯＶ Ａ程度である。それ故に
、この時は、定着ヒータ４には、電源１の電力容量から
みて許容される最大電流に近い電流を流す挙が許される
。Therefore, electrical parts other than the heat fixing device (such as various electric motors and exposure lamps) are not operating, and their power consumption is extremely small, usually several 1. It is about OVA. Therefore, at this time, the fixing heater 4 is allowed to flow a current close to the maximum allowable current in view of the power capacity of the power source 1.
一方、電流検出器３は、そこに流れる電流値−すなわち
、複写機内で消費されている電力に比例した電圧を発生
する。この検出電圧は交流であるので、整流器１１Ａに
よって直流に変換されたあと、オペアンプ１０で反転増
幅される。On the other hand, the current detector 3 generates a voltage proportional to the current value flowing therethrough, that is, the power consumed within the copying machine. Since this detected voltage is alternating current, it is converted to direct current by the rectifier 11A, and then inverted and amplified by the operational amplifier 10.
明らかなように、オペアンプ１０の出力電圧Ｅｏｕｔは
、前記消費電力が太きくて′電源容量に余裕がないほど
低く、反対に消費電力が少なくて電源容量の余裕が大き
いほど高い値となる。前記出力電圧Ｅｏｕｔは導通角制
御回路７に制御（調整）電圧として供給される。As is clear, the output voltage Eout of the operational amplifier 10 is low as the power consumption is large and there is no margin for power supply capacity, and conversely, the output voltage Eout of the operational amplifier 10 is high as the power consumption is low and there is a large margin for power supply capacity. The output voltage Eout is supplied to the conduction angle control circuit 7 as a control (adjustment) voltage.
導通角制御回路７は、前記制御電圧Ｅｏｕｔに応じて、
定着ヒータ４と直列に接続されたトライアック５の導通

制御する。The conduction angle control circuit 7, depending on the control voltage Eout,
The conduction angle of the triac 5 connected in series with the fixing heater 4 is controlled (corrected), and the current flowing through the fixing heater 4 is controlled.
このようにして、定着ヒータ４には、電源の電力容量か

値と比較されている。In this way, the fixing heater 4 is supplied with electric power corresponding to the remaining electric power obtained by subtracting the amount of electric power consumed by other electrical components from the electric power capacity of the power source. The maximum allowable power that can be supplied at a moment can be supplied. On the other hand, the fuser temperature sensor (in this example, a thermistor) 9
As a result, the temperature of the fixing device is detected, and the detection signal is supplied to the positive input terminal of the comparator 8. Further, a reference signal is supplied to the negative input terminal of the comparator 8. That is, the temperature of the fixing device is constantly compared with a reference value in the comparator 8.

加される。したがって、この場合は、前述したように、
定着ヒータ４には許容最大限の電力が供給され、定着器
の温度は最小の時間で規定値に達する。If the temperature of the fixing device is below the specified temperature, the output of the comparator 8 becomes high impedance, and the output voltage Eout of the operational amplifier 10 is applied to the conduction angle control circuit 7. Therefore, in this case, as mentioned above,
The maximum allowable power is supplied to the fixing heater 4, and the temperature of the fixing device reaches the specified value in the minimum time.

により、トライアック５は遮断され、定着ヒータ４への
給電が禁止される。On the other hand, when the fixing device reaches a specified temperature, the output of the comparator 8 becomes low impedance and low level, so the output Eout of the operational amplifier 10 is short-circuited. As a result, the triac 5 is cut off, and power supply to the fixing heater 4 is prohibited.

きる。As described above, according to the present invention, the total power consumption of the copying machine is detected, and if the detected value is less than the maximum allowable power based on the power supply capacity, the fuser heater is activated within the range that does not exceed the maximum allowable power. Since the maximum current is applied to the fuser, it is possible to accelerate the temperature rise of the fuser heated by the fuser heater to the maximum allowable speed. In particular, the warming-up time when the power is turned on is shortened, and the waiting time is minimized. It can be done.

ある。In the above embodiment, the power consumption of the fixing heater was controlled by controlling the conduction angle of the triac, which is the driver of the fixing beater. It is obvious that switching may be performed to control the power consumption.
