摘要： PURPOSE:To always obtain proper exposure by actuating a flash light emission circuit during a flash light emission time when it is controlled by a light quantity integration circuit when the luminance of field is smaller than a set lowest proper exposure allowable luminance. CONSTITUTION:A set diaphragm value signal 6 and a set second signal 24 are inputted in a set luminance arithmetic circuit 25 so as to output the set lowest proper exposure allowable luminance signal 27. When either a lens aperture driving signal 20 or a lens aperture output signal 28 is outputted in a state where a flash light emission signal 35 is outputted from a comparator 33 when the set luminance signal 27 is larger than an actual luminance signal 32, an OR circuit 36 generates an output and an AND circuit 38 energizes the flash light emission circuit 34 so as to emit flash lights during the flash light emission time when the circuit 34 is controlled by the light quantity integration circuit 44 which is controlled with a guide number and a film sensitivity. Thus, the proper exposure can be always obtained.

摘要： PURPOSE:To execute proper exposure by setting a proper guide number in a flash light emitting device and actuating it when the luminance of field is smaller than the lowest proper allowable luminance set by a set luminance arithmetic circuit. CONSTITUTION:When a set luminance signal 27 is larger than an object luminance signal 32 expressing the actual luminance of an object from a photometry device 31, an OR circuit 38 energizes the flash light emission circuit 34 so as to emit a flash light after outputting either a driving signal 20 from a control circuit 19 or an output signal 28 from a timer 26. A guide number arithmetic circuit 44 which works with the output 22 from a film sensitivity switching device 21 and the output 4 from a range finder 3 is provided in the titled camera, which is constituted so that the guide number to be set in the circuit 34 is computed to be given to the device 34, thereby always obtaining the proper exposure. When the set luminance signal 27 is smaller than the set lowest proper exposure allowable luminance, the guide number for the proper exposure is set in the circuit 34 so as to actuate the circuit 34.

摘要： PURPOSE:To obtain an inexpensive camera, whose structure is simple, having the precision in photographing equal to that of a conventional autofocusing camera by providing a range finder, a photometry device, a film sensitivity switching device and a flash light emitting device in a pan-focus camera and a zone focus camera. CONSTITUTION:A signal 2 expressing the set photographing distance of a photographic lens 1, a measured distance signal 4 expressing the measured distance from the range finder 3 and a set film sensitivity signal 22 from the film sensitivity switching device 21 are inputted in a diaphragm arithmetic circuit 5 so as to compute the set diaphragm value by which the position of an object is within the depth of field of the photographic lens 1 corresponding to the set film sensitivity, and a set diaphragm value signal 6 is outputted. Thus, the inexpensive camera whose structure is simple can always execute the photographing in which the precision is equal to that of the conventional autofocusing camera.

摘要： PURPOSE:To obtain an inexpensive camera, whose structure is simple, having an excellent photographing function equal to an autofocusing camera by providing a range finder in a pan-focus camera or a zone focus camera and setting a diaphragm in a desirable set diaphragm value. CONSTITUTION:A signal 2 showing the set photographing distance of a photographic lens 1 and a measured distance signal 4 showing the measured distance from a range finder 3 are inputted in a diaphragm arithmetic circuit 5 so as to compute the set diaphragm value by which the position of an object is within the depth of field of the photographic lens and a set diaphragm value signal 6 is outputted. When the opening of the diaphragm reaches the set diaphragm value, the diaphragm is held in the set diaphragm value or when the diaphragm value computed from the sensitivity of a film, the luminance of the field and a set exposing time is smaller than the set diaphragm value, it is held in the computed diaphragm value, by a control circuit 29. And also before the opening of the diaphragm reaches the set diaphragm value, closing actuation can be started. Thus, photographing whose precision is as excellent as that of a conventional autofocusing camera can be always possible by the inexpensive camera whose structure is simple.

摘要： PURPOSE:To increase the braking distance in the 2nd space and to stop a front blade group which travels at a high speed safely and surely, by increasing the number of blades constituting the front blade group so as to decrease the width in the traveling direction. CONSTITUTION:A front blade group 115 is constituted of a slit forming blade 115a, covering blades 115b, 115c, 115d, 115e and has an increased number of blades; therefore, the width in the traveling direction of each blade is small. In addition, the stop position of the group 115 is longer in a braking distance L by as mush as the decrease in the width. As a result, even if the group 115 is moved at a high speed, there is no need for stopping the same quickly; therefore, the impact in the stage of stopping can be decreased and the group 115 stops in the position shown by an alternate long and two short dashes line safely and surely. A rear blade group consists of a slit forming blade 116a and covering blades 116b, 116c, 116d, 116e.
摘要翻译：目的：增加第二空间中的制动距离，并通过增加构成前刀片组的刀片数量来减少行进方向的宽度，从而安全可靠地停止高速行驶的前刀片组。构成：前刀片组115由狭缝形成刀片115a，覆盖刀片115b，115c，115d，115e构成，刀片数量增加; 因此，各叶片的行进方向的宽度小。此外，通过与宽度的减小一样，组115的停止位置在制动距离L中更长。结果，即使组115高速移动，也不需要快速停止; 因此，可以降低停止阶段的冲击，并且组115可以安全可靠地停止在替代的长和短短划线所示的位置。后刀片组由狭缝形成刀片116a和覆盖刀片116b，116c，116d，116e组成。

摘要： PURPOSE:To provide a flash synchronizing device for a camera constituted so that the set position of an image frame size varying device is detected and a flash is made to emit light by closing a synchronizing switch for set image frame size. CONSTITUTION:When an image frame decision member is placed at the set positions of a first image frame, detection switches 14 and 15 are opened and a stroboscope bulb SB emits the light by closing the synchronizing switches for a first image frame 11c and 13. When it is placed at the set position of the second image frame, the switches 14 and 15 are closed and the stroboscopic bulb SB is made to emit the light by closing the synchronizing switches for a second image frame 11b and 12.
