    • A camera wherein a front housing which contains a photographing optical system, an exposure device, etc. is connected by a foldable connecting device such as a bellows or the like to a rear housing which contains a photosensitive material to be exposed to light, a view finder optical system, etc. During photographing, the foldable connecting device is stretched to adjust the distance between the front and rear housings to a distance suitable for photographing. When the camera is not in use, the connecting device is contracted to being the front and rear housings very close to each other. An electrical wiring arrangement of a flexible material is either provided on the surface of the bellows or formed together with the bellows as an integral part of the bellows when it is formed in such a way as to be stretchable and contractable together with the bellows, the wiring service to electrically connect the components disposed in the front housing to those disposed in the rear housing. In our embodiment, a main switch disposed in the rear housing is operable from a switch control device in the front housing when the bellows is fully expanded.
    • 一种相机,其中包含拍摄光学系统,曝光装置等的前壳体通过诸如波纹管等的可折叠连接装置连接到包含要暴露于光的感光材料的后壳体,视图 取景器光学系统等。在拍摄期间,可折叠连接装置被拉伸以将前壳体和后壳体之间的距离调整到适于拍摄的距离。 当照相机不使用时,连接装置收缩为彼此非常接近的前后壳体。 柔性材料的电线布置或者设置在波纹管的表面上,或者与波纹管一起形成为波纹管的一部分,当其形成为与波纹管​​一起可拉伸和收缩时 布线服务以将布置在前壳体中的部件电连接到设置在后壳体中的部件。 在本实施例中,当波纹管完全膨胀时,设置在后壳体中的主开关可从前壳体中的开关控制装置操作。

    • The disclosed automatic flash photography apparatus operates with a camera having a shutter in which a diaphragm blade serves as a shutter blade, and the diaphragm diameter is varied by varying the time interval from the moment its blades start opening till the moment they start closing. A switch switches over between separate time constant circuits, one for artificial-light photography, the other for natural-light photography. For flash photography, a resistor which is variable in response to the distance from a light source to an object and the film sensitivity controls the time constant circuits for closing the diaphragm blades. Thus a flash device is illuminated and the amount of light passing the diaphragm aperture is established.
    • 所公开的自动闪光摄影装置利用具有光阑叶片用作快门叶片的快门的相机操作,并且通过改变从其叶片开始开始到开始关闭的时刻的时间间隔来改变光阑直径。 一个开关在分开的时间常数电路之间切换,一个用于人造光线摄影,另一个用于自然光摄影。 对于闪光摄影,响应于从光源到物体的距离而变化的电阻器和胶片感光度控制用于关闭光圈叶片的时间常数电路。 因此,闪光装置被照亮,并且建立了通过光阑孔径的光量。

    • The present invention relates to an aperture setting device for camera at the time of photographing under day light as well as under flashlight. The device presents an aperture setting ring rotatable from the range of photographing under daylight to that under flashlight, being switched over according to the then photographing conditions, an information setting means to be moved according to the set information for photographing under flashlight such as information of the distance and an aperture ring for setting aperture, whereby the aperture ring is moved in engagement with the aperture setting ring in case the aperture setting ring is set for the range of photographing under daylight while the aperture ring is moved in engagement with the information setting means in case the aperture setting ring is set for the range of photographing under flashlight. In this way the aperture is set for photographing under daylight as well as under flashlight.
    • 本发明涉及在日光下以及在手电筒下拍摄时的照相机的光圈设定装置。 该设备呈现一个光圈设置环,其可以在日光下的拍摄范围内旋转到手电筒下的拍摄范围,根据当时的拍摄条件进行切换;根据用于在手电筒下拍摄的设置信息移动的信息设置装置, 距离和用于设置光圈的光圈环,由此当孔径设置环设置在日光下的拍摄范围的情况下,孔径环与孔径设置环移动,同时光圈环与信息设置接合而移动 用于在手电筒下拍摄范围设置光圈设定环的情况。 以这种方式,光圈设置为在日光下以及在手电筒下拍摄。
