摘要： A cassette for releasably holding a film unit and locating it at an exposure position therein. The cassette includes base and cover sections locatable in a closed position wherein a pressure plate assembly on the cover section is movable toward and away from the base section between a raised film release position and a lowered pressure applying position wherein the film is pressed between opposed bearing surfaces, one of which may be formed by an intensifying screen for x-ray applications, within the cassette to locate the film unit at the exposure position. A simply-constructed, low-cost pressure plate assembly latching system is provided including a pair of latch members having latch tabs thereon which are captured in corresponding detents on the pressure plate assembly to releasably hold the latch members in a cocked unlatching position. In response to movement of the pressure plate assembly to the lowered position, the tabs are released from the detents and the latch members move forwardly automatically to the latching position wherein the tabs engagingly overlie the exterior surface of the pressure plate assembly to hold it in the lowered position.

摘要： An arrangement for presenting light-sensitive sheets, especially X-ray film sheets, to a treating machine, especially to a developing machine, includes a closure which is mounted at an inlet opening of a withdrawing station of the machine for movement between a retracted position in which it is spaced from the inlet opening, and an extended position in which it light-tightly closes the inlet opening. The cassette containing the sheets to be withdrawn at the withdrawing station is mounted on a carriage for joint movement through the inlet opening and forms a movable unit therewith. An engaging member engages the movable unit and causes the closure to move into its extended position during the movement of the unit in an initial path section, while an unlatching device unlatches the lid of the cassette during the movement of the unit in an intermediate path section, and a lid-opening device opens the lid of the cassette during the movement of the unit in path terminal path section. A blocking device retains the lid during the return movement of the unit so that the lid is closed and latched before the closure is displaced into its retracted position. The carriage has a sealing plate which prevents manual displacement of the closure into the retracted position.

摘要： A film package containing a stack of notched films in a light-tight envelope is held vertically in a light-tight loading chamber by a clamp member engaging with the notches of the films. The lower end of the envelope is cut, and the envelope is moved vertically relative to the films until the films are projected from the lower end of the envelope while the films are clamped by the clamp member. The clamp member is then disengaged from the notches of the films, and the films are allowed to move down into a receiving chamber positioned under the loading chamber. Then, a shutter is closed between the receiving chamber and the loading chamber to shield the films in the receiving chamber from light.

摘要： A cassette for releasably holding a photosensitive film unit and locating the film unit at a film plane therein. The cassette includes base and cover sections coupled together in telescoping relation for movement toward and away from each other between releasably latched first and second closed positions. In the first closed position there is minimal pressure applied to the film unit to facilitate its removal from the cassette. When the case and cover sections are located in the second closed position sufficient pressure is applied to the film unit to urge it into intimate contact with a film plane defining bearing surface in the base section. In the illustrated embodiment the cassette is configured for radiographic applications and includes an intensifying screen that is urged into intimate contact with the film unit when the base and cover sections are located in the second closed positions.

摘要： Photographic apparatus usable with a large format film processor for receiving and supporting a cassette holding an exposed film unit and for unlatching structure on the cassette to substantially reduce pressure on the film unit to facilitate its movement over a film bearing surface as the film unit is advanced from the cassette into the entry of the film processor. The cassette includes differently configured forward and rear pressure latch release members and the apparatus includes conforming forward and rear latch release actuators. The actuators are configured to allow the forward release member to pass by the rear actuator without causing premature actuation of the forward release member.

摘要： A cassette that holds a large format photographic film unit of the self-developing type in a film plane for exposure to x-rays has a generally rectangular housing and a pressure plate disposed in the housing. The walls of the housing are in fixed relation to one another. A variable gap film-loading opening is defined at one transverse end of the housing and a second variable gap opening is provided at the opposite end for sliding removal of an opaque envelope surrounding the film unit. Springs resiliently urge the pressure plate into intimate, continuous contact with the film unit which also places the photosensitive layer of the film unit in intimate, continuous contact with an x-ray sensitive phosphor layer disposed adjacent the film plane. Operating members such as spring-loaded slide rods mounted in the longitudinal edges of the cassette are operatively connected to the pressure plate through one or more cam surfaces. Movement of the operating members in a direction parallel to the film plane is translated into a transverse movement of the pressure plate away from the film unit. This movement of the pressure plate releases the film unit and increases the housing openings to allow the sliding insertion and removal of the film unit and the sliding removal of the envelope. Light seals are preferably provided at the openings to ensure that the cassette is light tight when the film unit is loaded in the cassette for exposure.
摘要翻译： 在用于暴露于X射线的膜平面中保持自显影型的大幅面摄影胶片单元的盒具有设置在壳体中的大致矩形的壳体和压力板。 外壳的墙壁彼此固定。 在壳体的一个横向端部限定可变间隙膜装载开口，并且在相对端设置第二可变间隙开口，用于滑动移除围绕胶片单元的不透明包络物。 弹簧弹性地迫使压板与膜单元紧密连续地接触，膜单元也使膜单元的感光层与邻近膜平面设置的x射线敏感荧光体层紧密连续地接触。 安装在盒的纵向边缘的诸如弹簧加载的滑动杆的操作构件通过一个或多个凸轮表面可操作地连接到压力板。 操作构件在与薄膜平面平行的方向上的移动被转换成压板远离薄膜单元的横向移动。 压力板的这种运动释放胶片单元并增加壳体开口以允许胶片单元的滑动插入和移除以及信封的滑动移除。 优选地，在开口处设置光密封，以确保当胶片单元被装载在盒中用于曝光时，盒子是不透光的。

摘要： A cassette holder is provided for use with a wheeled stretcher or the like. The holder is slidably and pivotably mounted to a pair of support tubes positioned beneath the top board of the stretcher. It may accordingly be positioned beneath any portion of the top board which is desired. To replace an x-ray or other type of film cassette, the holder may be pivoted downwardly towards either side of the stretcher. A tray slides out from the holder to provide easy access to the cassette. The holder accepts cassettes from both sides of the stretcher depending upon which support tube is utilized as a pivot axis.

摘要： An x-ray film cassette includes two cassette parts which are connected at one side by a hinge and which are cylindrically curved as considered in a plane normal to the hinge. The cassette part which constitutes the bottom carries a foil of ferromagnetic material floatingly supported on an elastic strip-sloped peripheral frame, and an intensifying shield supported on this foil, while the other cassette part which constitutes the top carries a magnetic plate supported on elongated projections of the cassette wall and supporting another intensifying shield. In the closed position of the cassette, the magnetic plate attracts the ferromagnetic foil to thereby eliminate air inclusions between the intensifying shields and the x-ray film interposed therebetween.
