Platen for a print on demand digital device
View Patent ↗A platen for a print on demand digital device, such as a digital camera, is provided. The platen includes a print media transport roller located on a first side of a planar member to support print media. A cutting mechanism is located on a second opposite side of the planar member to sever the print media. The cutting mechanism includes a cutting wheel mounted to a block threaded on a rotating threaded rod. A pawl extends from the block and is arranged to incrementally rotate a counter wheel with each cutting action.
1. A platen for a print on demand digital device includes:
a planar member to support print media;
a print media transport roller located on a first side of the planar member to move the print media; and
a cutting mechanism located on a second opposite side of the planar member to sever the print media, the cutting mechanism including:
a transport assembly driven by a threaded rod, said transport assembly having a body;
a cutting edge fixed to the body; and
a member driven by the threaded rod to engage an edge of a counter, such that said cutting member is arranged to increment the counter with each severing operation.
2. A platen according to claim 1 , wherein the member comprises a pawl mounted upon the body and arranged to rotate the counter by engagement with the edge of the counter.
3. A platen according to claim 1 , further including a printhead capping mechanism.
4. A platen according to claim 3 , wherein the printhead capping mechanism is fast with the planar member.
5. A platen according to claim 4 , wherein the printhead capping mechanism includes biasing members arranged to bias a printhead capping member away from the platen.
6. A platen according to claim 5 , wherein the printhead capping mechanism includes an electromagnetic assembly to selectively overcome the biasing members.
7. A platen according to claim 6 , wherein the printhead capping mechanism includes an elongated sponge to blot the printhead.
8. A platen according to claim 6 , wherein the electromagnetic assembly includes a coil that acts as a solenoid.
