Problems solved by technology

The construction is not very efficient and not ergonomic
[0003] Second, since the ribbon core has to be slid onto and out of the ribbon adapter many times, this motion creates back-and-forth sliding wear that can damage the interface between the clip and the ribbon core
The printer has a tolerance for this problem, but if the damage exceeds the tolerance, you will end up with poor print quality

Embodiment 540

[0102] Embodiment 540 shows a wedge action between button 502 and push rod 504 . Each press of button 502 on ribbon adapter 520 moves button 502 and push rod 504 forward or backward (directions B and A). Also, when push button 502 is pressed such that force A is applied to push rod 504, push rod 504 rotates clockwise or counterclockwise due to the wedge force. In other words, each press of the button 502 on the ribbon adapter 520 will cause clockwise or counterclockwise rotation based on the wedge force between the button and the push rod. Each press of the cylindrical button also moves the button 202 and push rod 504 forward or backward (directions B and A). The wedge force is the point of application of force on the wedge. The end of the button 552 is the point of application (or points of application) and the end of the push rod 504 includes a wedge shape. In other words, one or more force application points at one end of the cylindrical button are positioned to interfac...

Abstract

The present invention includes a method and apparatus for improving ribbon replacement in thermal printers. The invention is also applicable to replacing other media in an associated printer. Improvements are made based on a ribbon adapter or media adapter designed for two states: 1) a snapped state for printing, and 2) a released state for land replacement of media in the printer. By clicking or pressing a button, the user can toggle between the two states. A print operation is performed during the snap state. The snap-fit ​​state ensures that there is little or no relative movement between the media core and the media adapter. The media adapter can also support media cores of different diameters. The release state is achieved when the user changes media. The released state may allow easier replacement of the media without significant force or pressure.

Description

technical field [0001] The present invention relates to apparatus and methods for improving the ribbon replacement process in thermal printers. Background technique [0002] In general, contemporary ribbon adapters use parts to snap onto the core of the ribbon. This part may be metal or may be plastic. This construction has two considerations. First, when a user replaces the ribbon in the printer, the user may need to use a lot of force to remove the ribbon core from the ribbon adapter and install a new ribbon core. Not only does the user need to overcome the gravity of the ribbon itself, but also the sliding friction between the ribbon core and the ribbon adapter because of the interference fit between the core and adapter. The construction is not very efficient and not ergonomic. [0003] Second, since the ribbon core must be slid onto and out of the ribbon adapter many times, this motion creates reciprocating sliding wear that damages the interface between the snap fi...
