Abstract

A credential production device includes a printing device, a laminating device, a transfer ribbon accumulator, a processing assembly, and a frame. The printing device is configured to print an image to the transfer ribbon. The laminating device is configured to transfer printed images from the transfer ribbon to a substrate. The transfer ribbon accumulator adjusts a length of a portion of a ribbon path, along which the transfer ribbon is routed, in response to different transfer ribbon feed rates. The processing assembly supports the transfer ribbon, at least a portion of the printing device or a portion of the laminating device, and at least a first portion of the transfer ribbon accumulator. The frame supports the second portion of the transfer ribbon accumulator. The processing assembly and the frame are configured to move relative to each other between first and second positions.

First claim

What is claimed is:

1. A credential production device configured to transfer print images using a transfer ribbon, the device comprising:
a printing device configured to print an image to the transfer ribbon;
a laminating device configured to transfer printed images from the transfer ribbon to a substrate;
a transfer ribbon accumulator configured to adjust a length of a portion of a ribbon path, along which the transfer ribbon is routed, in response to different feed rates at which the transfer ribbon is fed along the ribbon path through the printing and laminating devices;
a processing assembly supporting the transfer ribbon, at least a portion of the printing device or a portion of the laminating device, and at least a first portion of the transfer ribbon accumulator; and
a frame supporting a second portion of the transfer ribbon accumulator;
wherein the processing assembly and the frame are configured to move relative to each other between first and second positions.

2. The credential production device according to claim 1 , wherein the transfer ribbon accumulator is operative and engages the transfer ribbon when the processing assembly and the frame are in the first position.

3. The credential production device according to claim 2 , wherein the transfer ribbon accumulator is not operative and the transfer ribbon can be removed from, or loaded on the processing assembly when the processing assembly and the frame are in the second position.

4. The credential production device according to claim 1 , wherein:
the frame is a main frame of the device; and
the device further comprises a transport mechanism configured to feed individual substrates along a processing path having a fixed position relative to the main frame; and
the processing assembly is configured to move relative to the main frame and the processing path between operating and loading positions, which respectively correspond to the first and second positions.

5. The credential production device according to claim 1 , wherein:
the frame is an accumulator frame of the transfer ribbon accumulator that is supported by the processing assembly; and
the accumulator frame moves between operating and extended positions relative to the processing assembly, which respectively correspond to the first and second positions.

6. The credential production device according to claim 1 , wherein:
the transfer ribbon accumulator comprises a plurality of ribbon-engaging members (REM's);
the first portion of the transfer ribbon accumulator comprises at least one of the plurality of REM's;
the second portion of the transfer ribbon accumulator comprises at least one of the plurality of REM's;
the at least one REM of the first portion moves relative to the at least one REM of the second portion in response to movement of the processing assembly relative to the frame between the first and second positions.

7. The credential production device according to claim 6 , wherein the plurality of REM's includes a moveable REM configured to move relative to the frame to adjust the length of the portion of the ribbon path when the processing assembly is in the first position.

8. The credential production device according to claim 7 , wherein the transfer ribbon accumulator includes a drive system configured to generate a force that drives movement of the moveable REM relative to the frame.

9. The credential production device according to claim 7 , wherein the transfer ribbon accumulator includes first and second fixed REM's, each having a fixed position relative to the frame and configured to engage the transfer ribbon supported in the ribbon path.

10. The credential production device according to claim 9 , wherein the moveable REM moves relative to the fixed REM's and the frame along an axis that extends through a gap between the fixed REM's.

11. The credential production device according to claim 10 , wherein:
the drive system comprises a pinion, a rack that engages the pinion, and a drive force mechanism that drives rotation of the pinion;
the rack moves linearly relative to the pinion in response to rotation of the pinion; and
the moveable REM moves relative to the fixed REM's in response to rotation of the pinion.

12. The credential production device according to claim 11 , wherein the moveable REM is coupled to the rack and moves relative to the pinion in response to rotation of the pinion.

13. The credential production device according to claim 11 , wherein:
the second portion includes the first and second fixed REM's;
the first portion includes the moveable REM; and
the processing assembly and the moveable REM move relative to the frame and the first and second fixed REM's in response to relative movement of the processing assembly and the frame between the first and second positions.
