    • A mechanism for supporting said light-emitting device in said reproduction apparatus in an electrographic reproduction apparatus having a light-emitting device for forming, on a dielectric support member, a charge pattern corresponding image-wise to information to be reproduced. The light-emitting device support mechanism includes a carriage attached to the reproduction apparatus and movable relative thereto to a first operative position and a second remote position. A pivot mechanism is supported by the carriage so as to provide a pivot axis, the light-emitting device being mounted on the pivot mechanism for movement about the pivot axis. A reference feature is located in the reproduction apparatus, the reference feature located in a predetermined relation relative to the dielectric support member. A movable latch member is selectively engagable with the light-emitting device to move the light-emitting device from a first position, remote from the reference feature, movable with the carriage to the first operative position or the second remote position, to a second position in engagement with the reference feature to be operatively associated with the dielectric support member.
    • 一种用于在具有发光装置的电子照相再现装置中将所述发光装置支撑在所述再现装置中的机构,所述发光装置用于在电介质支撑构件上形成与要再现的信息相对应的图像的电荷模式。 发光装置支撑机构包括附接到再现装置并可相对于第一操作位置和第二远程位置移动的滑架。 枢轴机构由滑架支撑以提供枢转轴线,该发光装置安装在枢转机构上以围绕枢转轴线运动。 参考特征位于再现设备中,参考特征位于相对于电介质支撑构件的预定关系中。 可移动的闩锁构件可选择地与发光装置接合以将发光装置从远离参考特征的第一位置移动,使其能够与托架一起移动到第一操作位置或第二远程位置到第二位置 与参考特征接合以与电介质支撑构件可操作地相关联。

    • A web-tracking control apparatus including a mechanism for monitoring the cross-track force exerted on a moving flexible web as the web is transported along a desired travel path, and a control circuit utilizing the monitored force to provide for feedback control to correct tracking of the moving web. The web-tracking control apparatus for controlling the movement of a flexible web traveling about an adjustable support member includes at least one web edge contacting member contacting a marginal edge of the flexible web. A pivot assembly is operatively associated with the web edge contacting member while said web edge contacting member is in contact with a marginal edge of said flexible web. The pivot assembly is capable of deflecting a predetermined amount proportional to the force of the flexible web on the edge contacting member. A cross-track force monitoring mechanism is operatively associated with the pivot assembly for producing a signal representative of deflection of the pivot assembly. An electronic circuit responsive to the pivot assembly deflection signal provides a correction signal for causing adjustment of the position of the web support member so that the web support supports the flexible web for movement without any substantially cross-track force being exerted on the web edge contacting member.
