    • A camera consists of a lens barrel unit, a spool chamber unit, a Patrone chamber unit, and a substantially plate-like linking member. The linking member has a photographic aperture, and guide rails for restricting the position of a film relative to the photographic aperture. The linking member links the spool chamber unit and Patrone chamber unit. A picture size switching mechanism realizing a picture size switching function for partly blocking the photographic aperture is mounted on the linking member. The camera further includes a viewfinder picture size switching mechanism for switching viewfinder picture sizes, and a switching control unit for controlling the photographic picture size switching mechanism and viewfinder picture size switching mechanism so that a photographic picture zone and viewfinder picture zone will be set to the same picture size. After the viewfinder picture zone is switched from a large picture size to a small picture size, the photographic picture zone is wider than a field of view defined as the viewfinder picture zone.
    • 相机包括镜筒单元,卷轴室单元,Patrone室单元和基本上板状的连接构件。 连接构件具有照相孔和用于限制膜相对于照相孔的位置的导轨。 连接构件连接卷轴室单元和Patrone室单元。 实现用于部分遮挡照相孔径的图像尺寸切换功能的图像尺寸切换机构安装在连接部件上。 照相机还包括用于切换取景器图像尺寸的取景器图像尺寸切换机构,以及用于控制照相图像尺寸切换机构和取景器图像尺寸切换机构的切换控制单元,使得照相画面区域和取景器图像区域将被设置为 相同的图片大小。 取景器图像区域从大图像尺寸切换到小图像尺寸后,摄影图像区域比定义为取景器图像区域的视野宽。

    • Disclosed is an image forming apparatus for forming a toner image on a sheet both in a horizonal installation and in a vertical installation of the apparatus. The image forming apparatus is designed so that an air flow from a thermal fixing unit exerts no influence on an image forming operation of a photosensitive body and a temperature detection operation of the thermal fixing unit even when installed horizontally or vertically. This image forming apparatus therefore includes an exhaust duct for guiding a gas of an interior of the thermal fixing unit in an upper oblique direction from the thermal fixing unit to exhaust the interior Of the thermal fixing unit. The air flow from the thermal fixing unit does not therefore influence an image formation on the photosensitive body even when the apparatus is installed horizontally or vertically. This image forming apparatus also includes a temperature detector provided obliquely to a heat roller of the thermal fixing unit. The image forming apparatus further includes a plurality of temperature detectors each provided in a different position with respect to the heat roller of the thermal fixing unit. The image forming apparatus still further includes a temperature detector for detecting a temperature of the heat roller and a control circuit for controlling a fixing temperature of the heat roller by comparing a set temperature corresponding to an installing direction of the apparatus with a temperature detected by the temperature detector. The temperature of the heat roller can be therefore accurately controlled irrespective of the installing direction of the apparatus.
    • 公开了一种用于在水平安装和垂直安装中在片材上形成调色剂图像的图像形成装置。 图像形成装置被设计成使得即使在水平或垂直安装时,来自热定影单元的空气流也不影响感光体的图像形成操作和热定影单元的温度检测操作。 因此,该图像形成装置包括用于从热定影单元沿上倾斜方向引导热定影单元的内部的气体排出热定影单元的内部的排气管道。 因此,即使装置水平或垂直安装,来自热定影单元的空气流也不影响感光体上的图像形成。 该图像形成装置还包括倾斜于热定影单元的加热辊设置的温度检测器。 图像形成装置还包括多个温度检测器,每个温度检测器设置在相对于热定影单元的加热辊的不同位置。 图像形成装置还包括用于检测加热辊的温度的温度检测器和用于通过将与设备的安装方向相对应的设定温度与由该设备的安装方向相对应的温度进行比较来控制加热辊的定影温度的控制电路 温度检测器 因此,无论装置的安装方向如何,都可以精确地控制加热辊的温度。
