Abstract

The Figure shows an arrangement supporting a sliding platen in a desk top copier for sliding movement along a platen scanning path. Reproduction machine top 10 is provided with a bearing receiving slot 12 extending along the machine top in the direction desired for scanning movement. A captivated ball bearing strip 14 of a commercially available type is supported in slot 12. A slide member 15 with a slot complementary to ball strip 14 is supported on ball strip 14 for low friction sliding movement. Slide member 15 supports platen 18 in a slot along an edge thereof. Slide member 15 is maintained in contact with the captivated ball bearing strip 14, by housing 20, which is fixedly attached to machine top 10, and overlies the slide member 15. Facing surfaces of slide member 15 and/or support 20 may be provided with a Teflon wear strip 22 to reduce the friction in the engagement between the two members.
