摘要： An automatic exposure control apparatus of electric type for a photographic camera having an exposure control parameter setting means cooperative with a geometrical progression scale in isometric graduation is provided with a resistor device. The device includes a variable resistor having a grounded slider associated with the setting means upon movement thereof for providing a resistor value proportional to the amount of movement of the setting means, but to the reciprocal logarithm of the preselected parameter value. In order to minimize the complexity of a computer circuit responsive to the various outputs of the resistor device for performing photographic Appex computation, a bias voltage is applied to each of the variable resistors in a manner to produce a signal in the form of current proportional to the reciprocal of the amount of movement of the setting means. The resistor device has a single substrate having a plurality of resistor elements formed thereon by a metal coating technique and arranged for cooperation with respective sliders, thereby improving the exposure control accuracy and stabilization of the performance of the computer circuit against variation of temperature distribution in the apparatus.

摘要： A photographic camera having a magnetic actuating device associated with an electronic control device for initiating a release of one or more of the camera mechanisms from the cocked position thereof. In one embodiment of the invention, the magnetic actuating device comprises a single magnetic winding with a core material having a substantially rectangular hysteresis loop, and an armature of which the movement is controlled by the polarity of the magnetic winding and which is connected to spring-biased means for latching the mechanism in the cocked position. After the core is magnetized by applying a voltage to the magnetic winding for a relatively short period to hold the armature with the latching means in the cocked position against the force of the spring, the magnetic winding is energized by an output of the opposite polarity from the electronic control device causing the armature to move away from the core, whereby the release of the mechanism is initiated.

摘要： In an electromagnetic release for a camera a normally de-energized electromagnet is coupled with unitarally joined elongated pole pieces, and when energized, generates a magnetic flux opposing the magnetic flux of a permanent magnet. A moveable, magnetizable armature adjacent corresponding ends of the pole pieces is normally attracted by the pole pieces as a result of the flux of the permanent magnet when the electromagnet is deenergized. The permanent magnet is positioned between the pole pieces. A spring biases the armature to disengage it from the faces of the pole pieces.

摘要： The device includes a permanent magnet for attracting a movable iron armature. A pair of elongated rectilinear magnetic bodies have planar pole faces at one end facing the iron armature, and the permanent magnet is sandwiched between these two magnetic members intermediate their ends, with the permanent magnet extending perpendicularly to the magnetic members. Respective magnetizing windings embrace each magnetic member between the permanent magnet and the pole faces of the members, to produce a magnetic flux in the magnetic members opposing the flux provided by the permanent magnet so as to release the iron armature. In one embodiment of the invention, the other ends of the members, projecting beyond the permanent magnet, are angled to face each other to provide an air gap therebetween. In a second embodiment of the invention, the magnetic members or yokes have respective second windings thereon, beyond the permanent magnet, and the ends of these yokes, beyond the second windings, are formed with planar pole faces for operative association with a second iron armature. Both iron armatures are spring biased to disengage the magnetic yokes or members. As the permanent magnet engages the yokes intermediate their ends, the magnetic flux path due to the magnetizing windings does not include the permanent magnet and therefore an effective armature releasing magnetic flux can be provided with only a relatively small current supplied to the magnetizing windings.
