  • Patent number: 5740482
    Abstract: An LCD panel for displaying information in finder has an input terminal. In order to connect the input terminal and a driving circuit, an FPC board is employed. The LCD panel and the FPC board partially overlap each other so that the terminals of the LCD panel and the FPC board face each other with a cushion inserted therebetween. The cushion includes insulating portions and conductive portions. The overlapping portion of the LCD panel and the terminal are inserted into the slit so that the LCD panel, the cushion and the FPC board firmly contact each other. Thus, the display panel and the FPC board are electrically connected.

  • Patent number: 5729774
    Abstract: In a single use camera having a flash circuit and a film drive motor operated from a single battery source, a control circuit is provided with a diode that is coupled from a terminal on the motor control switch to the flash charging circuit to suppress operation of the flash charging circuit while the film drive motor is operating to advance the film after a picture taking event. The motor OFF position of the control switch is connected to battery positive terminal and the control circuit includes a capacitive connection from the switch to the flash charging circuit such that when the motor switch changes over from the motor ON to motor OFF position, a positive pulse is applied to restart operation of the flash charging circuit when the motor is turned off. This arrangement suppresses operation of the flash charging circuit while the motor is running, allowing full battery current to be applied to the motor.

  • Patent number: 5721977
    Abstract: A distance measuring apparatus includes a pair of line sensors. An image of an object is projected on the line sensor through a lens. The distance up to an object is measured according to the object image in the line sensor. The line sensor includes a plurality of pixels (CCD). The time period for respective pixels to complete charge accumulation with the pixel first completing charge accumulation as the pixel of quantizing reference becomes the data for the respective pixels. In the present invention, the range of pixels used for quantizing reference is altered according to variation in the focal length of the lens. The operation of distance measurement is terminated when charge accumulation for all the pixels within the range of the integration completion determination ends. The range of integration completion determination is altered according to the focal length, the measured brightness value and the shooting mode.
