摘要:
A media detection system includes a light source mounted within a cartridge receiving chamber defined by a cartridge engaging assembly. A cartridge referencing member has an arm portion mounted to the cartridge engaging assembly and a head portion located within the cartridge receiving chamber at a position adjacent the light source. The cartridge referencing member is deflected by a data cartridge within the cartridge receiving chamber so that when no data cartridge is located within the cartridge receiving member, the cartridge referencing member is not deflected and the cartridge referencing member blocks light from the light source. When a data cartridge is located within the cartridge receiving member, the cartridge referencing member blocks less light from the light source. A detector assembly mounted within the cartridge receiving chamber detects whether light from the light source is blocked or not blocked.

A picker for data cartridges in a computer information storage library. The picker includes a sleeve for transporting data cartridges, a thumb that can move in one dimension relative to the sleeve, and a single pivoting finger on the thumb. The single finger has an inboard pivot point which results in a self locking action (pulling makes the finger grip tighter). The finger has an armed state for gripping and a splayed state for release. Switching between states is passive, depending only on one dimensional motion of the thumb relative to the sleeve. The finger has a post that travels in tracks in the sleeve. Switching tracks switches finger states. A spring loaded gate in the tracks enables track switching. Potential cartridge wear and binding problems during extraction are eliminated by providing sleeve guides that limit cartridge rotation, by providing a concave guide surface in storage locations, and by proper selection of materials. A corresponding drive has a handle that must be manipulated. The picker includes thumb details for manipulating the drive handle.

Example embodiments disclosed herein relate to a print media jam clearance assembly for use in a printing device. The print media jam clearance assembly includes a first print medium jam clearance position and a second print medium jam clearance position. This is accomplished, in part, by a repositionable platen of the printing device.
摘要:
An apparatus for linearly displacing a cartridge engaging assembly along a predetermined displacement path and for supporting the cartridge engaging assembly at a fixed orientation relative to its displacement path. The apparatus includes single or multiple elongate flexible members fixedly secured to the cartridge engaging assembly at at least three points thereon, a flexible member engagement assembly (e.g. pulleys) fixedly positioned relative to the displacement path, and a drive assembly operatively connected to at least one elongate flexible member.

In one example, a media guide for use with a print bar includes a plate suspended over the print bar to guide a leading edge of print media away from printheads on the print bar during printing when the print bar is installed in a printer.
摘要:
A media cartridge insertion apparatus for a media cartridge storage and handling system for use in association with a media cartridge of the type having a rear end portion which is adapted to be inserted into a media drive and having a forward end portion which is adapted to be grasped by a human operator for handling the cartridge comprising a cartridge receiving assembly for receiving a cartridge in a predetermined orientation therewith, said cartridge receiving assembly being displaceable between a first relatively rotated operating position and a second relatively rotated operating position angularly displaced from said first operating position.

Cylinder-to-cylinder attachment method and construction featuring nonutiltion of mechanical fasteners or bonding, especially advantageous for attachment of cylinders which are composite or to be subjected to hydrostatic pressure. A fastening ring is interpositionally and rotatively engaged and aligned with a toothed axial end of each cylinder whereby the inwardly radial teeth for each cylinder appropriately mesh with the outer grooved circumferential surface of the fastening ring. The resultant joint is easily detachable and less susceptible than conventional joints to damage, breakage, degradation, stress concentrations and fluid infiltration.
摘要:
A circumferential rib-stiffened hollow cylinder and method for fabrication thereof featuring construction of the cylinder from complementarily shaped nestled prefabricated rings and resultant circumferential ribs which are integral with the rest of the cylinder. In one embodiment ring sections which are "L"-shaped in cross-section are axially and sequentially mated; ring sections which are "U"-shaped are axially and correspondingly integrated therewith, therein for a cylinder having internal circumferential ribs and thereout for a cylinder having external circumferential ribs. The dominant load path for the cylinder is through the reinforced cylinder elements, and the cylinder's wall-thickness-to-diameter ratio is effectively reduced, thereby allowing radial reinforcement of the ribs, reducing residual stresses and increasing strength; these advantages are especially significant for cylinders which are composite or are to be subjected to hydrostatic pressure. Moreover, in comparison with conventional cylinders of monocoque construction, manufacture and quality control may be expected to be more economical and cost-effective.
摘要:
Data cartridge exchange apparatus for use in a data storage system may include a moveable cartridge storage array having at least a first data cartridge storage location and a second data cartridge storage location. The first data cartridge storage location is operatively associated with the second data cartridge storage location so that the first data cartridge storage location is independently moveable with respect to the second data cartridge storage location when the second data cartridge storage location is accessible by the data storage system.
