    • When a lens unit is to be mounted, the lens unit is moved downward along guide grooves, whereby an opening portion cover is also pushed down counter to an elongation force of coil springs, the lens unit is mounted to a camera body, and the opening portion cover is moved to an open position. When the lens unit is to be removed, the lens unit is moved along the guide grooves, whereby engagement with the guide grooves is released. Because the opening cover portion is urged from the open position to a closed position by the coil spring at this time, the opening portion cover is moved with the lens unit along the guide grooves and fixed at the closed position.
    • 当要安装透镜单元时,透镜单元沿着引导槽向下移动,由此开口部分盖也相对于螺旋弹簧的伸长力被推下,透镜单元安装到照相机主体上,并且开口 部分盖移动到打开位置。 当要移除透镜单元时,透镜单元沿着引导槽移动,从而释放与引导槽的接合。 由于此时开口盖部分由螺旋弹簧从打开位置推动到关闭位置,所以打开部分盖沿导向槽移动并固定在关闭位置。

    • There is disclosed a distance measuring equipment capable of performing efficiently a greater accuracy of focusing without troubling an operator, and a camera incorporating thereinto such a distance measuring equipment. By the use of the first focusing algorithm switches 61, 62 and 63 set up to the turn-off state, the turn-off state and the contact 62a side, respectively, so that AF-dedicated photo detector circuit 40 performs once a ratio arithmetic processing in accordance with photo-currents I1 and I2 from the PSD 30. In case of the short distance area, they are dealt with as the focusing data. In case of the middle distance area, the ratio arithmetic processing is performed by n times. In case of the long distance area, by the use of the second focusing algorithm switches 61, 62 and 63 set up to the turn-off state, the turn-on state and the contact 62b side, respectively, so that the ratio arithmetic processing is performed in accordance with the photo-current I1 and the constant current Ir from the constant current source 50. In case of the longest distance area, by the use of the third focusing algorithm switches 61, 62 and 63 set up to the turn-on state, the turn-off state and the contact 62b side, respectively, so that the light quantity arithmetic processing is performed in accordance with the additional values of the photo-currents I1 and I2 and the constant current Ir to determine focusing data.
    • 公开了一种距离测量设备,其能够有效地执行更高的聚焦精度,而不会使操作者困扰,并且将相机并入其中的这种距离测量设备。 通过使用分别设置为关断状态的第一聚焦算法开关61,62和63,关断状态和接触62a侧,使得AF专用光电检测器电路40执行一次比率算术 根据来自PSD 30的光电流I1和I2进行处理。在短距离区域的情况下,它们被作为聚焦数据处理。 在中间距离区域的情况下,比率算术处理执行n次。 在长距离区域的情况下,通过分别使用设置为截止状态的第二聚焦算法开关61,62和63,导通状态和触点62b侧,使得比率算术处理 根据来自恒流源50的光电流I1和恒定电流Ir进行。在最长距离区域的情况下,通过使用设置为转向电流的第三聚焦算法开关61,62和63, 导通状态,关断状态和触点62b侧,使得根据光电流I1和I2的附加值和恒定电流Ir执行光量算术处理以确定聚焦数据。

    • A digital camera is composed of a camera body and a lens unit removebly attached to the camera body. When the lens unit is attached to the camera body, the lens unit and camera body send and receive control signals by antennas and wireless I/Fs each disposed on the lens unit and the camera body, respectively. In addition, data of the image captured with the lens unit is sent to the camera body by serial drivers, each disposed on the lens unit and the camera body, through connection contacts that electrically connect the lens unit and the camera body. When the lens unit is detached from the camera body, on the other hand, the control signals are sent and received by the antennas and the wireless I/Fs, and the image data is sent by the wireless communication.
    • 数码相机由照相机主体和透镜单元组成,取出并附着在照相机主体上。 当镜头单元安装在照相机主体上时,镜头单元和照相机主体分别通过天线和每个设置在镜头单元和相机机身上的无线I / F发送和接收控制信号。 此外,通过将透镜单元和照相机主体电连接的连接触点将通过镜头单元拍摄的图像的数据发送到相机主体,串行驱动器设置在镜头单元和相机主体上。 另一方面,当镜头单元与相机机身分离时,控制信号由天线和无线I / F发送和接收,并且通过无线通信发送图像数据。
