Abstract: The disclosed system for securely latching a device in a support frame employs a pair of latching members each adapted to pivot about a latch pivot axis defined on an exterior side of the support frame and are adapted to engage a corresponding latch recess on the device downstream from the first latch pivot axis. The first and second latching members pivot toward the interior of the support frame to securely engage the respective first and second latch recesses and automatically pivot further toward the interior of the support frame within the engaged first and second latch recesses in case of an unplanned attempt to release the device from the support frame.

Abstract: A system for securely latching a device in a support frame comprises a first latching member adapted to pivot about a first latch pivot axis defined on one side of the support frame and to engage a corresponding first latch recess on the device downstream from the first latch pivot axis. The system also comprises a second latching member adapted to pivot about a second latch pivot axis defined on an opposite side of the support frame and to engage a corresponding second latch recess on the device downstream from the second latch pivot axis. The system further comprises a first spring operatively coupled between the support frame and the first latching member upstream from the first latch pivot axis and a second spring operatively coupled between the support frame and the second latching member upstream from the second latch pivot axis.

Abstract: A print media roll holder includes a multi-diameter core adapter for mounting print media rolls of different core sizes. The roll holder comprises a ring-shaped frame having a base portion provided with a guide rack which is used for positional adjustment. The multi-diameter core adapter is pivotally mounted inside the ring-shaped frame on two opposing lateral pins inserted through the frame and through the core adapter for 180 degree rotation in a clockwise or counter-clockwise direction depending on the size of core being used. The guide rack is part of a rack and pinion gear system used to vary the spacing between the roll holders in a reciprocal linear fashion.
