Abstract

A device for processing media may include a system and method for loading and unloading consumable supplies of a printer, and more particularly, a system and method for providing a compact form factor printer which provides convenient access to the replaceable components of the printer. A printer may include a base and a lid hingedly attached to the base, moveable between a closed position in which the lid is secured to the base, and an open position. A cavity may be defined between the lid and the base, where the cavity is inaccessible when the lid is in the closed position and the cavity is accessible when the lid is in the open position. The printer may include a ribbon positioning assembly disposed within the cavity.

First claim

That which is claimed:

1. A ribbon cartridge comprising:
a first spool housing configured to receive a first spool;
a second spool housing configured to receive a second spool; and
at least one frame member connecting the first spool housing and the second spool housing;
wherein the at least one frame member extends from a first end attached to the first spool housing, along a length between the first spool housing and the second spool housing to a second end attached to the second spool housing,
wherein the at least one frame member defines:
a first portion between the first spool housing and the second spool housing having a first width in a direction perpendicular to the length; and
a recessed portion between the first spool housing and the second spool housing having a second width in the direction perpendicular to the length, and

wherein the first width is greater than the second width.

2. The ribbon cartridge of claim 1 , further comprising a radio frequency identification tag disposed proximate the first end of the at least one frame member.

3. The ribbon cartridge of claim 1 , further comprising a spool lock defining a locked position and an unlocked position, wherein the spool lock is biased in the locked position with at least one of the first spool or the second spool, wherein the spool lock in the locked position precludes rotation of the at least one of the first spool or the second spool, and wherein the spool lock is driven against the bias to the unlocked position in response to being inserted into a media processing device.

4. The ribbon cartridge of claim 3 , wherein the spool lock comprises a pawl, and the at least one of the first spool or the second spool comprises a plurality of recesses disposed about a barrel of the spool, wherein each of the plurality of recesses are configured to receive at least a portion of the pawl in response to the spool lock being disposed in the locked position to preclude rotation of the spool.

5. The ribbon cartridge of claim 4 , wherein the pawl is biased into engagement with the recesses disposed about the barrel of the spool, and wherein the spool lock is disengaged in response to driving the pawl against the bias.

6. The ribbon cartridge of claim 3 , wherein the spool lock comprises a first spool lock and a second spool lock, wherein the first spool lock in the locked position is configured to engage and preclude rotation of the first spool and wherein the second spool lock in the locked position is configured to engage and preclude rotation of the second spool.

7. The ribbon cartridge of claim 3 , wherein the spool lock comprises an engagement surface, wherein the spool lock is driven against the bias toward the unlocked position in response to the engagement surface being engaged by a driving element of the media processing device.

8. The ribbon cartridge of claim 1 , wherein a printhead receiving aperture is defined between the first spool housing and the second spool housing, and between a first one of the at least one frame member and a second one of the at least one frame member.

9. The ribbon cartridge of claim 8 , wherein a first channel is defined in the first one of the at least one frame member and a second channel is defined in the second one of the at least one frame member, wherein the first channel and the second channel cooperate to define a printhead guide to guide a printhead through the printhead receiving aperture.

10. The ribbon cartridge of claim 1 , wherein the recess is configured to receive a projection of a printhead assembly in response to the printhead assembly being moved along a printhead assembly guide channel.

11. A ribbon cartridge comprising:
a first spool housing configured to receive a first spool;
a second spool housing configured to receive a second spool; and
a frame member extending from a first end adjacent to the first spool housing to a second end adjacent to the second spool housing;
wherein a first portion of the frame member has a lesser width relative to a second portion of the frame member, the first and second portions of the frame member being located between the first spool housing and the second spool housing.

12. The ribbon cartridge of claim 11 , further comprising a spool lock, wherein the spool lock is biased into a locked position configured to engage at least one of the first spool or the second spool.

13. The ribbon cartridge of claim 12 , wherein the spool lock is configured to be driven against the bias to an unlocked position in response to the ribbon cartridge being received within a media processing device.

14. The ribbon cartridge of claim 12 , wherein the spool lock is biased into the locked position in engagement with both the first spool and the second spool, and wherein the spool lock is configured to maintain a tension of a ribbon extending between the first spool and the second spool when the spool lock is engaged with the first spool and the second spool.

15. The ribbon cartridge of claim 12 , wherein the first spool is a ribbon supply spool, and wherein the second spool is a ribbon take-up spool, and wherein a radio frequency identification chip is disposed proximate the take-up spool.

16. The ribbon cartridge of claim 11 , wherein the first portion of the frame member defines a recess.

17. The ribbon cartridge of claim 16 , wherein the frame member comprises additional structural reinforcement proximate the recess relative to a majority of the frame member.
