    • A neghold assembly permits withdrawal of a disc-like film unit from a clamping aperture assembly stationarily positioned on the photographic printer that holds a selected film frame at the print gate aperture. The disc-like film unit is held on a movable film transport assembly which engages a switching mechanism that actuates the clamping aperture assembly to an open position, releasing the disc-like film unit before the transport assembly can be moved from a print exposure cycle position. The film transport assembly includes a film transport base that is slidably attached to the printer and is positionable in the print exposure cycle position. A disc film holder, positioned on the transport base, holds the disc-like film units and rotationally indexes selected film frames to the print gate for clamping by the clamping mechanism.
    • 负压组件允许将盘状胶片单元从固定位于照相打印机上的夹持孔组件中取出,该照相打印机在打印门孔处保持所选择的胶片框架。 盘状胶片单元被保持在可移动胶片传送组件上,该可移动胶片传送组件接合将打开位置驱动夹紧孔组件的切换机构,在传送组件可以从打印曝光周期位置移动之前释放盘状胶片单元 。 薄膜输送组件包括可滑动地附接到打印机并可定位在打印曝光循环位置的薄膜输送基座。 位于传送基座上的盘片保持器保持盘形胶片单元,并将所选择的胶片框架旋转地转印到打印门以通过夹紧机构进行夹紧。

    • A disc film holder holds a generally disc-like photographic film unit having a plurality of image frames and indexes and disc-like photographic film unit to position selected image frames at a predetermined position, such as a print gate aperture in a photographic printer. The disc-like film unit is held coaxially about a central post and is rotationally indexed about a central axis. When the film unit is rotated for indexing a selected image frame to the print gate aperture, the film unit is biased upwardly to an indexing position so that both the top and bottom surfaces of the film is maintained out of contact with any surface during rotation. When the disc has been indexed so that the selected image is in alignment with the print gate aperture, the film unit is forced downwardly to a non-indexing position and the frame to be printed is clamped at the print gate aperture for transferring an image to photographic print paper.
    • 盘片保持器保持具有多个图像帧和折射率的盘状摄影胶片单元和盘状摄影胶片单元,以将选定的图像帧定位在诸如照相打印机中的打印门孔的预定位置。 盘状胶片单元围绕中心柱同轴地保持,并围绕中心轴旋转地编制索引。 当胶片单元旋转以将所选择的图像帧分度到打印门孔时,胶片单元向上偏压到分度位置,使得胶片的顶表面和底表面在旋转期间保持与任何表面不接触。 当光盘被索引以使所选择的图像与打印门孔对齐时,胶片单元被强制向下到非索引位置,并且要打印的框架被夹紧在打印门孔处以将图像传送到 照相打印纸。

    • A ratchet assembly properly positions selected film frames at a film gate aperture of a photographic printer. The ratchet assembly includes a ratchet wheel rotatably attached to a base having a plurality of ratchet teeth. Each tooth has a rotation-prevention edge and a ramped edge with the ramped edge being inclined toward the rotation-prevention edge of an adjacent tooth. A positioning pawl is pivotally attached to the base proximate a first end and has a head portion proximate a second end. The head portion has a first edge adapted to slidably engage the ramped edge of the ratchet wheel. The head portion of the positioning pawl is biased against the ratchet wheel such that if the ratchet wheel is indexed too far and does not properly position the selected film frame at the print gate aperture, the head portion forces the ratchet wheel to move back by slidably engaging the ramped surface of the ratchet wheel until an alignment pawl engages a notch located on the periphery of the disc film unit. The notch is in a precisely defined spatial relationship to the selected film frame at the print gate aperture and the alignment pawl ensures that the selected film frame is optically centered.
    • 棘轮组件将所选择的胶片框架适当地定位在照相打印机的胶片门孔处。 棘轮组件包括可旋转地附接到具有多个棘齿的基座的棘轮。 每个齿具有防旋转边缘和倾斜边缘,斜坡边缘朝相邻牙齿的防旋转边缘倾斜。 定位爪在第一端附近枢转地附接到基座,并具有接近第二端的头部。 头部具有适于可滑动地接合棘轮的斜坡边缘的第一边缘。 定位棘爪的头部被偏压在棘轮上,使得如果棘轮被分度太远并且没有将选定的胶片框架适当地定位在打印门孔处,则头部分迫使棘轮回滑动地滑动 接合棘轮的倾斜表面,直到对准爪接合位于盘片单元的周边上的凹口。 凹口处于与打印门孔处的所选胶片框架精确限定的空间关系,并且对准棘爪确保所选择的胶片框架是光学中心的。

    • A paper mask produces even width borders on bordered photographic prints even if the unexposed photographic print paper is misaligned, angularly mistracking, or wandering in alignment through roll feeding, or if the width of the paper varies. The paper mask apparatus includes a base which is mounted on the paper deck of the printer and front and rear guides which are movably mounted to the base and have masking lips which overhang the longitudinal edges of the print paper. The front and rear guides are generally parallel to one another and are urged toward one another by bias springs. A separate masking frame of the desired print size is mounted to one of the two guides and moves with that guide to define transverse masking edges.
