摘要： A miniature single lens reflex camera using cassette film is disclosed. The camera can be operated with inexpensive lenses not having large back focus, due to the addition of a glass block between the shutter and the film plane. The finder optical system is short in actual length due to the combination of a trapezoidal prism, a right angle prism, and an equilateral prism.

摘要： The present invention is a film feed mechanism having a take-up shaft spaced apart from the film take-up spool. A bell crank is connected via a link to a conventional film feed control disc coupled to the take-up shaft. The reciprocal movement of the link is applied to the bell crank. The bell crank is provided with a first pawl and a second pawl. When the bell crank is moved to the right, the first pawl is in engagement with a first gear, which via second and third gears, causes the spool gear to be rotated counter-clockwise; however, the second pawl is slidingly disengaged from a rotating fourth gear. When the bell crank is moved to the left, the second pawl is in engagement with the fourth gear, which via a fifth, second and third gears cause the spool gear to be rotated counter-clockwise; however, the first pawl is slidingly disengaged from the rotating first gear. Thus, the present invention causes the spool gear to be rotated counter-clockwise in both directions of reciprocal movement of the link, and consequently, provides a widning torque of substantially constant level to the spool gear.
摘要翻译：本发明是一种胶片输送机构，其具有与胶卷卷轴隔开的卷取轴。钟形曲柄通过连杆连接到耦合到卷取轴的常规胶片馈送控制盘。连杆的往复运动应用于曲柄。钟形曲柄设置有第一棘爪和第二爪。当曲拐向右移动时，第一棘爪与第一齿轮啮合，第一齿轮经由第二和第三齿轮使得卷轴齿轮逆时针旋转; 然而，第二棘爪与旋转的第四档滑动地脱离。当曲拐向左移动时，第二棘爪与第四齿轮接合，第四齿轮通过第五，第二和第三齿轮使得卷轴齿轮逆时针旋转; 然而，第一棘爪与旋转的第一齿轮滑动地脱离。因此，本发明使卷轴齿轮在连杆的往复运动的两个方向上逆时针旋转，从而为卷轴齿轮提供基本上恒定水平的宽阔的扭矩。

摘要： A mirror operating mechanism in a single-lens reflex camera using a small film cassette. The mirror operating mechanism has a main plate having two guide shafts in parallel with the optical axis of the photographing lens of the camera and provided in the space between the picture opening and the film winding chamber of the film cassette. A mirror lifting drive plate and a mirror lowering drive plate are slidable along the two guide shafts, respectively. Driving coil springs are provided in parallel with the two guide shafts for driving said mirror lifting drive plate and mirror lowering drive plate, respectively.

摘要： An electro-mechanical shutter release delay apparatus includes a front curtain lock lever 4 sharing a common pivot axis 6 with a release lever 5 and joined to the latter by a spring 7. The depression of a shutter release rod 8 initially rotates the release lever 5 to close a first switch S.sub.1 which energizes front and rear curtain holding magnets M.sub.1 and M.sub.2. Continued depression tensions the spring and eventually closes a second switch S.sub.2. The latter energizes a flood lamp and initiates a time delay circuit, whose output deenergizes the front curtain holding magnet. The spring then rotates the lock lever to release the front curtain and commence the exposure, by which time the lamp has reached maximum intensity. After the proper exposure time has elapsed the rear curtain holding magnet is deenergized to release the rear curtain and terminate the exposure.Self-timing may be implemented by increasing the delay period provided by the time delay circuit, and including a notched holding lever 10 to latch the release lever 5 in its rotated position.
摘要翻译：机电快门释放延迟装置包括前窗帘锁定杆4，共享共同的枢转轴线6与释放杆5并通过弹簧7与之相连。快门释放杆8的按压最初使释放杆5旋转关闭对前后帘保持用磁铁M1，M2进行通电的第一开关S1。持续的凹陷使弹簧张紧，并最终关闭第二个开关S2。后者为泛光灯供电并启动延时电路，其输出使前帘保持磁体通电。然后，弹簧旋转锁定杆以释放前帘并开始曝光，此时灯已达到最大强度。经过适当的曝光时间后，后帘保持磁铁被断电以释放后帘并终止曝光。

摘要： A cassette type single lens reflex camera includes a longitudinally extending zoon lens system and a replacable film cassette disposed in opposite sides of the camera casing, the cassette having enlarged film storing opposite end sections joined by a tubular film guide with an inwardly vertically facing framing window. A 45.degree. semitransparent first mirror intercepts the zoom lens longitudinal optical axis to reflect lens traversing light through a rear lens group onto a second 45.degree. mirror mounted in the casing in the space between the cassette end sections and oriented to deflect the light from the first mirror to the cassette window. The light traversing the first mirror traverses, successively imaging and field lenses an erecting prism and an eyepiece lens which define a viewfinder.

摘要： Automatic exposure control is enhanced by providing a fixed diaphragm equivalent to the maximum aperture of the adjustable camera diaphragm so that the fixed diaphragm limits the maximum aperture to a consistent value. Consistent light measurements are possible as long as the lens being used does not interfere with the quantity of light entering the diaphragm.

摘要： A simple mechanism is provided for winding film in a film cassette in which a pawl engages a perforation in each film frame to actuate a film stop device which, in turn, disengages the pawl from the perforation to remove any force from the film during picture taking. Winding force is transmitted from a unidirectionally rotating film feed disc to a reciprocating link and then to a undirectionally rotating spool gear which drives the film spool.
