Abstract
A printer including a paper guide auxiliary member for guiding recording paper to the vicinity of the lower end of a printing area in which a print head performs printing, a paper side regulating member formed of elastic material for guiding both sides outside of the printing area of recording paper transferred from the paper guide auxiliary member towards the exit of the recording paper, and a gap forming member located outside of recording paper path and pressed between the paper side regulating member and platen. The recording paper is guided along the platen by the paper side regulating member while being transferred in the predetermined gap formed between the paper side regulating member and platen without frictional force, thereby avoiding the need for a mask plate which often causes problems.
Claims15
A printer comprising:
- a platen member;
- a paper guide auxiliary member for guiding recording paper supplied to a printing surface of said platen member;
- a paper side regulating member for guiding a side portion of the recording paper passing through said paper guide auxiliary member;
- and
- a gap forming member located outside a recording paper path in which the recording paper is transferred and for providing a predetermined minimum gap between said paper side regulating member and the printing surface of said platen member;
- wherein said gap forming member comprises a projection formed on one of said platen member and said paper side regulating member, said projection contacting the other one of said platen member and said paper side regulating member to maintain said predetermined minimum gap therebetween.
A printer comprising:
- a platen member;
- a paper guide auxiliary member for guiding recording paper supplied to a printing surface of said platen member;
- a paper side regulating member for guiding a side portion of the recording paper passing through said paper guide auxiliary member;
- and
- a gap forming member located outside a recording paper path in which the recording paper is transferred and for providing a predetermined gap between said paper side regulating member and the printing surface of said platen member;
- wherein said platen member has a platen protruding therefrom forming the printing surface;
- and
- said gap forming member has a thickness equal to a sum of (a) a distance that said platen protrudes from said platen member and (b) said predetermined gap.
A printer comprising:
- a platen member;
- a paper guide auxiliary member for guiding recording paper supplied to a printing surface of said platen member;
- a paper side regulating member for guiding a side portion of the recording paper passing through said paper guide auxiliary member;
- and
- a gap forming member located outside a recording paper path in which the recording paper is transferred and for providing a predetermined gap between said paper side regulating member and the printing surface of said platen member;
- wherein said paper side regulating member is formed of an elastic material;
- said printer further comprising a manual cutter disposed downstream of the printing surface of said platen member in a direction in which the recording paper is transferred, and said paper side regulating member extends at least to said manual cutter along said recording paper path;
- wherein said manual cutter comprises a skirt section for guiding into said recording paper path the leading edge of the recording paper transferred from said printing surface along said paper side regulating member;
- and
- wherein said manual cutter is disposed for pivotal motion, and said paper side regulating member biases said manual cutter so that said manual cutter is disposed at a predetermined position in which said skirt section of said manual cutter guides the recording paper into said recording paper path.
