Abstract

A handheld print-on-demand digital device. The device comprises a pagewidth inkjet printhead and a platen assembly operatively positioned relative to the printhead. The platen assembly comprises: a planar platen member for supporting print media; a print media transport roller located on a first side of the platen member for feeding print media past said printhead; and a cutting mechanism located on a second opposite side of the platen member for severing the print media. The cutting mechanism includes a transport assembly driven by a threaded rod. The transport assembly has a body for traversing across the print media and a cutting edge fixed to the body for severing the print media during a traverse of the body.

Claims (15)

1. A handheld print-on-demand digital device comprising:

a pagewidth inkjet printhead; and

a platen assembly operatively positioned relative to said printhead, said platen assembly comprising:

a planar platen member for supporting print media;

a printhead capping mechanism;

a print media transport roller located on a first side of the platen member for feeding print media past said printhead; and

a cutting mechanism located on a second opposite side of the platen member for severing the print media, the cutting mechanism including:

a transport assembly driven by a threaded rod, said transport assembly having a body for traversing across the print media; and

a cutting edge fixed to the body for severing said print media during a traverse of the body.

2. The device of claim 1 , wherein said cutting mechanism further includes 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

3. The device of claim 2 , wherein the member comprises a pawl mounted on the body and arranged to rotate the counter by engagement with the edge of the counter.

4. The device of claim 1 , wherein the printhead capping mechanism is fastened to the planar member.

5. The device of claim 4 , wherein the printhead capping mechanism includes biasing members arranged to bias a printhead capping member away from the platen.

6. The device of claim 5 , wherein the printhead capping mechanism includes a solenoid for moving the printhead capping member into capping engagement with the printhead.

7. The device of claim 1 comprising, which is a digital camera.
