摘要： The present invention relates to a lens unit construction for motion picture and other type projectors. The unit is provided with a motion picture projecting lens construction, a mantle cover to be fixed on the fixing position of the motion picture projector body, a guide device for slidingly guiding and holding the lens construction holding device on the device plate in such a manner that the construction holding device is slidable only along the direction of the optical axis of the lens construction and an adjusting device for operating the slide motion of the construction holding device. The construction holding device or the adjusting device is provided with a cam follower pin while the other is provided with a focus adjusting cam groove in which the cam follower pin is engaged. An engaging device guides the cam follower pin so that it can be easily introduced into the cam groove at the time of assembling the construction holding device with the adjusting device to form one body and for preventing the cam follower pin from being easily brought out of the cam groove in such a manner that the construction holding device is cooperatively coupled with the adjusting device.
摘要翻译：本发明涉及一种用于电影和其它类型投影仪的镜头单元结构。该单元设置有电影投影透镜构造，固定在电影投影机主体的固定位置上的罩套，以这种方式将透镜构造保持装置滑动引导并保持在装置板上的引导装置施工保持装置仅能够沿着透镜结构的光轴的方向滑动，以及用于操作施工保持装置的滑动运动的调节装置。施工保持装置或调整装置设有凸轮从动销，另一个设置有凸轮从动销接合的调焦凸轮槽。接合装置引导凸轮从动销，使得在组装具有调节装置的结构保持装置时可以容易地将其引入到凸轮槽中，以形成一体，并且用于防止凸轮从动销容易地从凸轮槽，其结构保持装置与调节装置协作地联接。

摘要： A sound motion picture projection apparatus provided with pressure pad means operable to press a film against magnetic sound recording and reproducing head means disposed along a path of the film for sound recording and/or reproduction. Urging means urge the pressure pad means toward its film pressing position. Externally operable means are provided for shifting the pressure pad means from its film pressing position to a released position against the urging force of the urging means. Releasable locking means are provided for holding the pressure pad means in the released position against the urging force of the urging means; and film detecting means are disposed in said sound film path behind the magnetic head means to detect introduction of the film into the sound film path and to release the locking of the pressure pad means by the locking means. Thereby, when film introduction into the film path for sound recording and/or reproduction is detected by the film detecting means, the pressure pad means is automatically changed from the released position to the film pressing position.
摘要翻译：一种具有压力垫装置的声音电影投影装置，可操作以将胶片按压在胶片的路径上设置的磁记录和再现磁头装置，用于声音记录和/或再现。推动装置迫使压力垫装置朝向其胶片按压位置。提供外部可操作的装置，用于克服施力装置的推动力将压力垫装置从其胶片按压位置移动到释放位置。提供了可释放的锁定装置，用于克服施力装置的作用力将压力垫装置保持在释放位置; 并且胶片检测装置设置在磁头装置后面的所述声音路径中，以检测胶片进入声音膜路径并通过锁定装置释放压力垫装置的锁定。由此，当通过胶片检测装置检测到用于声音记录和/或再现的胶片通道的胶片介质时，压力垫装置自动地从释放位置改变到胶片按压位置。
