    • Apparatus for transferring photosensitive sheets from the transporting plane into the copying plane of a photographic copying machine has a suction chamber with a perforated cover having a flat upper side which defines the copying plane. The interior of the suction chamber is subdivided into one or more centrally located primary sections which are in direct communication with the intake of a suction pump and two or more secondary sections which communicate with the primary section or sections by way of narrow passages defined by internal partitions of the suction chamber so that a sheet which is advanced in the transporting plane to a position of register with the cover is attracted first to that portion or those portions of the cover which overlie the primary section or sections and thereupon to those portions of the cover which overlie the secondary sections. The number of primary and secondary sections which communicate with the intake of the suction pump is reduced when the apparatus is used for transfer of smaller sheets. The number of perforations per unit area of that portion of the cover which overlies the primary section or sections is greater than the number of perforations per unit area of that portion of the cover which overlies the secondary sections, and the combined cross-sectional area of perforations in communication with the primary section or sections is greater than the combined cross-sectional area of passages between the primary and secondary sections.
    • 用于将感光片从传送平面传送到照相复印机的复印平面中的设备具有一吸气室,该抽吸室具有限定复制平面的平坦上侧的多孔盖。 吸入室的内部被细分成一个或多个居中定位的主要部分,其与抽吸泵的入口直接连通,以及两个或更多个次级部分,其通过由内部限定的狭窄通道与主要部分连通 使得在输送平面中前进到与盖对齐的位置的片材首先被吸引到覆盖在主要部分或部分上的那个部分或盖的那些部分或其上的那些部分 覆盖在二级部分上。 当将该装置用于较小的纸张的传送时,与抽吸泵的进气口连通的主部分和次部分的数量减少。 覆盖在主要部分上的盖的该部分的每单位面积的穿孔数量大于覆盖在次级部分上的盖的该部分的每单位面积的穿孔数目,并且组合横截面积 与主要部分或部分连通的穿孔大于主要部分和次要部分之间的通道的组合横截面面积。

    • A photographic copying machine wherein any one of a series of masks, each having a differently dimensioned light-transmitting opening, can be placed onto a locating plate which supports a battery of fixedly mounted or mobile magnetic actuators for discrete electric switching elements. Each mask carries a different array of soft magnets which displace or otherwise influence a group of actuators so that the thus influenced actuators open or close the associated switching elements which adjust the exposure controls and/or another system of the copying machine in dependency on the size and/or shape of the opening in the selected mask. The soft magnets on each mask influence a different group (e.g., a different number) of actuators each of which is an H-shaped permanent magnet.
    • 一种照相复印机,其中可以将具有不同尺寸的透光开口的一系列掩模中的任何一个放置在支撑用于离散电开关元件的固定安装的或移动的磁性致动器的电池的定位板上。 每个掩模携带不同的软磁体阵列,其移动或以其他方式影响一组致动器,使得受影响的致动器打开或关闭相关联的开关元件,其根据尺寸来调节曝光控制和/或复印机的另一系统 和/或所选掩模中的开口的形状。 每个掩模上的软磁体影响不同的组(例如不同数量)的致动器,每个致动器都是H形永磁体。

    • A rotary format-mask carrier plate carries a plurality of removably supported format masks for originals to be copied and carries them back and forth between the copying station and a change station, where the masks can be exchanged for others and/or copied originals replaced by not yet copied originals. Downwardly extending projections on the format masks extend through and beyond corresponding openings in the rotary carrier plate. While a format mask is transported from the change station to the copying station, it rests on the carrier plate. When it reaches the copying station, the carrier plate descends an amount such that the projections on the format mask come to rest on correspondingly arranged stationary electromagnets, thereby transferring the weight of the format mask to the stationary electromagnets. The carrier plate drops a further amount, losing physical contact with the format mask at the copying station. In this way, shaking or vibration of the format-mask carrier plate, resulting from laying on and removal of originals and format masks at the change station, cannot be transmitted to the format mask and original presently located at the copying station.
    • 旋转格式掩模载体板携带多个可拆卸支撑的用于要复制的原稿的格式掩模,并在复印站和更换站之间来回携带它们,其中可以将掩模交换为其他和/或复制的原件替换为 尚未复制原件。 格式掩模上的向下延伸的突起延伸穿过旋转载板中相应的开口并超出其中。 当格式化掩模从更换站传输到复印站时,它将放在载板上。 当到达复印台时,承载板下降一定量,使得格式掩模上的突起停留在相应布置的固定电磁体上,从而将格式掩模的重量传送到固定电磁体。 载体板进一步下降,与复印台的格式掩模失去物理接触。 以这种方式,由于在更换台上放置和移除原稿和格式化掩模产生的格式掩模载板的抖动或振动不能传输到当前位于复印台的格式掩码和原稿。
