    • A fixing device has a fixing unit and a temperature detection unit. The fixing unit includes a heat roller provided with a roller section and a heater section, and a pressure roller in pressure contact with the heat roller. These rollers are disposed in a protective cover. The roller section includes a base layer of aluminum formed into a hollow cylindrical shape, a black radiation layer, and a toner parting layer. The heater section is disposed in a hollow space of the base layer. In this heat roller, when heat is emitted from the heater section, and the heat is transmitted to the radiation layer via the base layer, greater amount of infrared radiation is emitted from the radiation layer than in the case of a heat roller that is not equipped with the radiation layer. The temperature detecting unit includes an infrared radiation sensor. Thus, even if a noise component is absorbed to some extent by locating the sensor at a distance from the heat roller on an outside of the protective cover, the temperature of the heat roller is detected accurately.
    • 定影装置具有定影单元和温度检测单元。 定影单元包括设置有辊部和加热部的加热辊以及与加热辊压接的加压辊。 这些辊子设置在保护罩中。 辊部分包括形成中空圆柱形状的铝基底层,黑色辐射层和调色剂分离层。 加热器部分设置在基层的中空空间中。 在该加热辊中,当从加热器部分发出热量,并且热量经由基底层传递到辐射层时,从辐射层发射的红外线辐射量比不是 配有辐射层。 温度检测单元包括红外线辐射传感器。 因此,即使通过将传感器定位在距保护罩外侧的加热辊一定距离处,某种程度的噪声成分被吸收,也能准确地检测出加热辊的温度。

    • An optical code reader includes a reading window, a reading control circuit for sensing an image of a 2-dimensional code via the reading window in a state where the reading window is set within a preset distance from the 2-dimensional code and converting the sensed image into image data, a guide light source for applying a guide light beam to permit the 2-dimensional code to be guided within the reading range of the reading control circuit, and a portable frame having an opening used as the reading window, for accommodating the reading control circuit and guide light source. In the optical code reader, the guide light beam indicates the center of the reading range and is applied from the guide light source except for a period during which the image of the 2-dimensional code is sensed by the reading control circuit.
