摘要： An exposure display device for a single lens reflex camera including light display elements for displaying either shutter speed or diaphragm value is disclosed. Nominal values representing either shutter speed or diaphragm value are marked on a glass plate disposed in the vicinity of the focusing plate of the camera's viewfinder. A first display section, comprising a first set of light display elements aligned with (and, if desired, located inbetween) the nominal values, creates a first exposure component (e.g. diaphragm value or shutter speed) display whose value is related to predetermined exposure conditions, such as object brightness, film sensitivity and the other exposure component (e.g. shutter speed or diaphragm value). A second display section, comprising a second set of light display elements, also aligned with the nominal values, creates a second display of the exposure component chosen to be displayed. The second display represents the actual position of the camera element controlling the displayed exposure component.

摘要： An automatic exposure control device is disclosed which is capable of aperture dominant and shutter speed dominant exposure control operation as well as manual exposure control operation. A logarithmic compression circuit including transducers develops voltages directly dependent upon the APEX indicating quantities Bv, Sv, Tv and Av. For automatic operation one of the voltages dependent upon Tv or Av is set into the circuit by manual control, and the other is calculated by the APEX indication formula Bv + Sv = Tv + Av, and applied as an output to the shutter control or aperture control mechanism. An indicator means is connected in the circuit to provide Tv or Av indications depending on the exposure control mode selected for the camera.

摘要： An automatic exposure control device for a single lens reflex camera characterized in that a stop determining member which stops down diaphragm blades by rotation thereof at a predetermined speed is released by a shutter release plate. A time constant circuit is started to operate simultaneously with the start of rotation of said stop determining member, and the rotation of said stop determining member is stopped by an electromagnetic mechanism when a time has lapsed. The length of said time linearly corresponds to the stop size determined by APEX operation based on the output voltage of said time constant circuit as an operation factor.

摘要： A shutter speed digital display device for cameras equipped with both automatic and manual shutter speed controls is disclosed. A shutter speed display control circuit generates a first digital signal in accordance with the adjustment of the camera's shutter speed by an automatic shutter speed control circuit. The first digital signal is decoded and used to control a light-transmitting liquid crystal device display. In addition, when the camera is in a manual mode of operation, the first digital signal is compared with a second digital signal related to manually adjusted shutter speed. If the comparisons are equal, a coincidence indicator is energized.

摘要： An automatic iris adjustment control for cameras which, using the APEX operational equations, compares the brightness value Bv and film sensitivity value Sv with the iris size indication value Av and shutter speed value Tv. The iris size indicating value Av is derived from the sum of pulses created by a pulse generator which operates in conjunction with the moving adjustment of the iris size. When the values are compared and found equal, an electro-magnet is de-energized stopping the movement of the adjustable iris at the correct iris setting.

摘要： A mechanical arrangement is disclosed for blocking the electric shutter operation of a camera when the rear shutter holding electromagnet is not energized sufficiently to hold the rear shutter. A pair of gears for the front and rear shutters, respectively, are mechanically linked to the shutters to prevent their running when the gears are held stationary. A release controlled lever holds the front shutter gear stationary, and the stationary position of the front shutter gear holds the rear shutter gear stationary. When the release button is depressed the front gear is released from the lever and rotates as the front shutter runs to an unblocking position. Rotation of the front gear frees the rear gear, but the rear shutter is held by the electromagnet until the exposure time is completed. Thereafter the electromagnet is deenergized causing the rear shutter to run to its blocking position and the rear shutter gear to rotate. If the electromagnet is not sufficiently strong, e.g. because of a reduction in battery power, to hold the rear shutter, both shutters will start to run and both gears will start to rotate simultaneously. A lever held in a first position by the starting position of the rear shutter gear, moves to a second, blocking position, when the rear shutter gear starts to rotate. When in the blocking position, the lever stops further rotation of the front shutter gear which, in turn, stops further rotation of the rear shutter gear. The operator, as a result, hearing no running sound of the shutters knows there is a failure in the electromagnet circuitry.
摘要翻译： 公开了一种机械装置，用于在后挡板保持电磁体没有被充分地通电以保持后挡板时阻挡相机的电动快门操作。 分别用于前百叶窗和后百叶窗的一对齿轮机械地连接到百叶窗上，以防止当齿轮保持静止时它们的运行。 释放控制的杆将前快门齿轮固定住，并且前快门齿轮的静止位置保持后快门齿轮静止。 当释放按钮被按下时，前挡板从杠杆释放并且随着前快门运行到解锁位置而旋转。 前轮的旋转释放后齿轮，但后挡板由电磁铁保持，直到曝光时间完成。 此后，电磁铁被断电，导致后挡板运行到其阻挡位置，并且后挡板齿轮旋转。 如果电磁体不够牢固，例如 由于电池功率的降低，为了保持后挡板，两个快门将开始运行，两个齿轮将同时开始旋转。 当后挡板齿轮开始旋转时，由后挡板齿轮的起始位置保持在第一位置的杠杆移动到第二阻挡位置。 当处于阻挡位置时，杠杆停止前快门齿轮的进一步旋转，其进而停止后快门齿轮的进一步旋转。 因此，操作者听不到百叶窗的运行声音，知道电磁铁电路有故障。
