摘要： An exposure control apparatus has a photometry unit for measuring the brightness at a plurality of divisional areas of a subject screen. A correct exposure time is calculated in accordance with signals obtained by measuring the brightness at the plurality of divisional areas with the photometry unit when a shutter blade is closed. A light-receiving aperture is formed in the shutter blade. The photometry unit or another photometry unit is disposed at the back of the shutter blade to thereby measure light from the subject screen as the shutter blade is opened. When the measured value takes a value corresponding to the exposure time, the shutter blade is closed.

摘要： A control system for a camera controls a shutter release operation electromagnetically. A signal generating circuit produces a switching signal for operating a switching circuit which supplies current to a control circuit for a camera. The signal generating circuit is in a condition to always produce a switching signal when a camera operation member is set to normal photographing modes other than the bulb photographing mode, and is out of condition to produce the switching signal during the time between actuation of a magnet and termination of the shutter opening operation. The closing operation of the shutter is checked by means of a mechanical control member during the release when the camera operation member is set in the bulb photographing mode.

摘要： An electromagnetic shutter controlling device releases the shutter to start exposure when the device is energized and completes exposure when the device is deenergized.The electromagnetic shutter controlling device is constituted of a shutter blade for opening and closing the shutter aperture, a first driving spring for closing or releasing the shutter blade, an electrical delay circuit for controlling exposure time, an electromagnetic device including an armature attracted by the magnetic force of the electromagnetic device and being connected to the electrical delay circuit, a second driving spring which is strained by the attraction of the armature so as to release or close the shutter blade when it is released, and a retaining member for keeping the shutter blade at the aperture closing position until it is actuated to release the shutter blade by the attraction of the armature.The armature is actuated by the magnetic attraction of the electromagnetic device first to strain the second driving spring, then to release the stop restraining the shutter blade so that exposure is started. The electromagnetic device is deenergized after a predetermined period of exposure time controlled by the delay circuit to complete the exposure by releasing the armature to return to the resting position and by actuating the previously strained driving spring to drive the shutter blade to close the shutter aperture.A trigger switch is closed simultaneously with the attraction of the armature to energize the delay circuit.

摘要： A control device for the shutter of a camera comprises an opening member for opening a shutter aperture to initiate taking of an exposure, a closing member for closing the aperture to complete the exposure, and opening and closing pawls for respectively retaining the opening and closing members at their charged position. A control member actuated during the shutter release motion releases the engagement of the opening pawl from the opening member, and a governor is provided for delaying the operation of the control member. An interlock lever is actuated by the opening member to release the engagement of the closing pawl from the closing member, and an exposure time setting cam is provided for adjustably setting the motion of the governor so as to shift the interlock lever between its working position and rest position. The interlock lever is positioned at its rest position when the exposure time setting cam is set to its high speed adjusting position so that the control member successively releases the opening pawl and the closing pawl while the interlock lever is positioned at its working position when the exposure time setting cam is set to its middle speed adjusting position so that the motion of the control member is delayed by the governor after the opening member is released from the opening pawl by the control member before the opening member actuates the interlock lever to release the closing member.

摘要： An electrical shutter includes a locating member which maintains a shutter drive member at rest at its start position and which is constrained in abutment against the drive member in conjunction with a charging member, which rotates in response to a film winding operation, as a prime mover spring is being charged, thus holding the drive member against inadvertent movement. The locating member also urges a detent member against an electromagnet which is operative to control the closing operation of a shutter. The electrical shutter also includes switches which are associated with a data entry unit and a strobo unit and which are closed in response to an opening operation of the shutter.

摘要： An auxiliary brake control device for use in an automatic exposure camera of the lens stop value control type permits the lens stop operation to be controlled with high accuracy without substantially increasing the lens stop operation time. The auxiliary brake control device is controlled by comparing the variation rate in the measured light which passes through the lens stop with a preset value. In this way, lenses which have different characteristic variation rates can be freely interchanged.

摘要： A "scanning type" photographic shutter blade mechanism is manually actuated to open, thereby commencing a photographic exposure cycle, by a resilient opening drive element. The "scanning type" shutter blade mechanism is thereafter closed to terminate the photographic exposure cycle by deenergizing an electromagnet which in turn releases a shutter blade closing drive member resiliently biased to engage the shutter blade mechanism and move it to the closed position against the yieldable bias of the opening drive element. Subsequent manual deactuation of the camera operates to recock the shutter blade closing drive member so as to ready the camera for a subsequent photographic exposure cycle.
