Abstract
A printer having a paper handling mechanism that includes a paper feed roller pair located upstream of a recording head. The paper feed roller pair includes a roller having a roller axis and a follow-up roller having a follow-up roller axis. A line between the roller axis and the follow-up axis is inclined towards the recording head. A paper discharge roller pair located downstream. The paper discharge roller pair includes a discharge roller having a discharge roller axis and a discharge follow-up rolling having discharge follow-up roller axis. A line between the discharge roller axis and the discharge follow-up roller axis is inclined towards the recording head.

A printer having a recording head, comprising:
- a paper feed roller pair disposed upstream of said recording head, said paper feed roller pair including a drive roller having a roller axis and a follow-up roller having a follow-up axis, a line intersecting both said roller axis and said follow-up axis being inclined towards said recording head, wherein said follow-up roller is located closer to said recording head than said drive roller;
- a paper discharge roller pair disposed downstream of said recording head, said paper discharge roller pair including a discharge drive roller having a discharge roller axis and a discharge follow-up roller having a discharge follow-up roller axis, a line intersecting both said discharge roller axis and discharge follow-up roller axis being inclined towards said recording head, wherein said discharge follow-up roller is located closer to said recording head than said discharge drive roller;
- and
- a platen, said platen being disposed between said paper feed roller pair and said paper discharge roller pair, said platen being substantially parallel to said recording head.
A printer having a recording head, comprising:
- a paper feed roller pair disposed upstream of said recording head, said paper feed roller pair including a roller having a roller axis and a follow-up roller having a follow-up axis, a line intersecting both said roller axis and said follow-up axis being inclined towards said recording head;
- a paper discharge roller pair disposed downstream of said recording head, said paper discharge roller pair including a discharge roller having a discharge roller axis and a discharge follow-up roller having a discharge follow-up roller axis, a line intersecting both said discharge roller axis and discharge follow-up roller axis being inclined towards said recording head;
- and
- a platen, said platen being disposed between said paper feed roller pair and said paper discharge roller pair, said platen being substantially parallel to said recording head, wherein a first nip portion is formed between said roller and follow-up roller, a second nip portion is formed between the discharge roller and follow-up discharge roller, said platen has a first flat face that is adjacent to and lower than said first nip portion;
- an upwardly rising slope portion adjacent said first flat face;
- a second flat face disposed across a paper gap from said recording head adjacent said upwardly rising slope portion;
- a downwardly descending slope portion adjacent said second flat face;
- and a third flat face that is lower than said second nip portion, and disposed between said second nip portion and said downwardly descending slope portion.
