    • This invention provides a connector which can positively effect coupling and detaching of a female connector, prevent electric shock and short-circuiting, and prevent an electric failure arising from contamination by extraneous substances. A lid plate 15 is biased by a compression coil spring 22 so that the lid plate is held by limit projections 26 at a protection position for covering male terminals 12 when a female connector is not coupled to the connector. Even if the lid plate 15 is pushed down by an external force so that the male terminals 12 are exposed from the lid plate 15, it can return to the protection position by itself when the external force is released. Since the lid plate 15 is constrained from rotating circumferentially at the protection position, the male terminal 12 smoothly passes through a terminal-through hole 16 in the lid plate 15 when the female connector 40 is inserted into a hood 13 and then the male terminals 12 are connected to female terminals 43. When the female connector 40 is extracted from the hood 13, the lid plate 15 is moved to the protection position by a bias of the compression coil spring 22. The terminal-through holes 16 in the lid plate 15 are closed by deformable tongue pieces of a dust-proofing rubber plate 150 to prevent the entrance of dust, water, or the like.
    • 本发明提供一种连接器,其可以有效地影响母连接器的耦合和拆卸,防止触电和短路,并且防止由外来物质污染引起的电气故障。 盖板15被压缩螺旋弹簧22偏压,使得当阴连接器未连接到连接器时,盖板被限位突起26保持在用于覆盖阳端子12的保护位置处。 即使盖板15被外力推下,使得阳端子12从盖板15露出,当外力被释放时,它也可以自身返回到保护位置。 由于盖板15被限制在保护位置周向旋转,所以当阴连接器40插入罩13中时,阳端子12平滑地穿过盖板15中的端子通孔16,然后阳端子12 连接到阴端子43.当阴连接器40从罩13抽出时,盖板15通过压缩螺旋弹簧22的偏压而移动到保护位置。盖板15中的端子通孔16 被防尘橡胶板150的可变形的舌片封闭,以防止灰尘,水等的进入。

    • A pseudo focal length camera which takes a photograph using an optical system of a single focal length. A printed photograph has a feature similar to that obtained by taking a photograph using an optical system comprising a plurality of photographing lenses each having a different focal length. Information indicating an image forming area corresponding to a designated pseudo focal length is recorded on a film when a photograph is taken and a printing is carried out based on the information. The view finder optical system includes a liquid crystal display for displaying the size of an image forming area which changes according to a magnification corresponding to each pseudo focal length. After the image forming area is determined by designating a pseudo focal length, the first switch is turned on by the depression of the release button in the first state. As a result, the lens of the view finder optical system is driven and consequently, the image corresponding to the determined image forming area appears in the whole area of the view finder. An exposure is effected by the depression of the release button to the second stage.
    • 使用单个焦距的光学系统拍摄照片的伪焦距照相机。 打印的照片具有与通过使用包括多个具有不同焦距的多个摄影镜头的光学系统进行照片而获得的相似的特征。 指示与指定的伪焦距对应的图像形成区域的信息在拍摄照片并基于该信息进行打印时被记录在胶片上。 取景器光学系统包括用于显示根据与每个伪焦距对应的放大率而变化的图像形成区域的尺寸的液晶显示器。 在通过指定伪焦距来确定图像形成区域之后,通过在第一状态下按下释放按钮来打开第一开关。 结果,取景器光学系统的透镜被驱动,因此,与所确定的图像形成区域相对应的图像出现在取景器的整个区域中。 通过将释放按钮按压到第二阶段来实现曝光。

    • A photographic camera of the type including a piezo-electric actuating element driven by energy accumulated in a capacitor for actuating a shutter wherein the piezo-electric element operates in stability to assure accurate appropriate opening and closing operation of the shutter of the camera and the capacitor is charged up rapidly to allow subsequent photographing operation to be done in a minute. In the camera, a charged voltage of the capacitor is checked several times to determine if it is sufficient to assure proper operation of the piezo-electric element, and if a then required level is not reached, then the capacitor is charged to the required voltage. While the capacitor is being charged, charging of a capacitor for a flash is inhibited. For operation of the shutter, a negative voltage is first applied across the piezo-electric element to set the same to its fixed home position, and then a positive voltage is applied to move the shutter from the home position to a predetermined opening position, whereafter the negative voltage is applied again to return the shutter to its initial position rapidly. The position of the shutter is also checked to assure proper operation of the camera.
    • 一种照相机,其类型包括由积累在用于致动快门的电容器中的能量驱动的压电致动元件,其中压电元件稳定地操作以确保相机和电容器的快门的精确的适当的打开和关闭操作 充电充电以允许随后的拍摄操作在一分钟内完成。 在相机中,检查电容器的充电电压几次以确定是否足以确保压电元件的正常工作,并且如果未达到所需的电平,则将电容器充电至所需电压 。 当电容器正在充电时,禁止对闪光灯的电容器充电。 对于快门的操作,首先在压电元件上施加负电压以将其设定为其固定的原始位置,然后施加正电压以将快门从原始位置移动到预定的打开位置,此后 再次施加负电压以快速将快门返回到其初始位置。 还检查快门的位置以确保相机的正常操作。

    • The disclosure relates a piezoelectric element-drive type shutter apparatus for camera. The shutter apparatus includes a main piezoelectric element having a free end which is able to move between a closed position and an opening position to drive shutter blades so as to be opened and closed, and an auxiliary piezoelectric element having a free end for urging the shutter blades toward its closed position when the free end of the main piezoelectric element returns from the opening position to the closed position. When the main piezoelectric element returns to the closed position, i.e. an initial position, the auxiliary piezoelectric element assists the returning movement of the main piezoelectric element. Accordingly, the shutter blades can be closed at a very high speed. This is very effective particularly when a small aperture of the shutter blade is desired. Furthermore, since the returning movement of the main piezoelectric element includes a compulsory force of the auxiliary element as well as a returning force of itself, the returning movement of the main piezoelectric element is insured to be stable as well as speedy, so that very accurate exposure can be obtained.
    • 本发明涉及一种用于照相机的压电元件驱动型快门装置。 快门装置包括主压电元件,其具有能够在关闭位置和打开位置之间移动的自由端,以驱动快门叶片以便打开和关闭;以及辅助压电元件,其具有用于推动快门的自由端 当主压电元件的自由端从打开位置返回到关闭位置时,叶片朝向其关闭位置。 当主压电元件返回到关闭位置即初始位置时,辅助压电元件有助于主压电元件的返回运动。 因此,快门叶片可以以非常高的速度关闭。 特别是当需要快门叶片的小孔时,这是非常有效的。 此外,由于主压电元件的返回运动包括辅助元件的强制力以及其自身的返回力,所以主压电元件的返回运动保证稳定且快速,从而非常准确 可以获得暴露。
