    • An image forming apparatus includes a fixing unit having a heat source, a temperature detecting unit for detecting a temperature of the fixing unit, an initial operation necessity detecting unit for determining whether an initial operation should be performed in the image forming apparatus, an initial operation selecting control unit for selecting an initial operation from among a plurality of predetermined initial operations based on the temperature detected by the temperature detecting unit when the initial operation necessity detecting unit detects that the initial operation should be performed, and a control unit for controlling the fixing unit so that the fixing unit performs the initial operation selected by the initial operation selecting control unit. Furthermore, a temperature control apparatus includes a determination unit for determining, based on the detected temperature of the body, whether the temperature of the body should be increased or decreased, a temperature increasing control unit for applying an AC voltage from the AC power supply to the heater so that the temperature of the body is increased when the determination unit determines that the temperature of the body should be increased, and a temperature decreasing control unit for applying to the heater a pulse-shaped AC voltage which is repeatedly turned on and off at a frequency so that the temperature of the body is decreased when the determination unit determined that the temperature of the body should be decreased, the frequency being generally not perceived by people.
    • 图像形成装置包括具有热源的定影单元,用于检测定影单元的温度的温度检测单元,用于确定在图像形成装置中是否应执行初始操作的初始操作必要性检测单元,初始操作 选择控制单元,用于当初始操作必要性检测单元检测到应该执行初始操作时,基于由温度检测单元检测到的温度从多个预定初始操作中选择初始操作;以及控制单元,用于控制定影 单元,使得定影单元执行由初始操作选择控制单元选择的初始操作。 此外,温度控制装置包括:确定单元,用于基于身体的检测温度来确定身体的温度是否应当增加或减少;温度上升控制单元,用于将来自AC电源的AC电压施加到 所述加热器使得当所述确定单元确定应该增加所述身体的温度时所述身体的温度增加;以及降温控制单元,用于向所述加热器施加重复打开和关闭的脉冲状AC电压 使得当确定单元确定应该减小身体的温度时,人体的温度通常不被人感觉到,从而使身体的温度降低。

    • There is provided a device in an accessory apparatus, which is connected with a main apparatus, for protecting a motor driver IC and a logic circuit in the accessory apparatus from the application of a voltage higher than the rated voltage for these circuits, when the connection between the main apparatus and the accessory apparatus (optional apparatus) which receives power from the main apparatus enters an abnormal state. Therefore, even when the power of the main apparatus is ON, the accessory apparatus can be attached to, or removed from, the main apparatus without damaging the circuits. The device comprises an inexpensive element, such as a rectifying diode or a Zener diode.
    • 在附件装置中设置有与主装置连接的装置,用于在连接时保护附件装置中的电动机驱动器IC和逻辑电路免受对这些电路的额定电压高的电压的影响 在主装置和从主装置接收电力的附件装置(可选装置)之间进入异常状态。 因此,即使主设备的电源接通,辅助设备也可以安装在主设备上或从主设备移除,而不会损坏电路。 该器件包括廉价元件,例如整流二极管或齐纳二极管。
