Abstract
A sheet gripping mechanism includes a first sheet guide including a guide surface facing a sheet conveyance path along which a sheet is to be conveyed and a second sheet guide which faces the first sheet guide across the sheet conveyance path. The second sheet guide includes a protuberance extending toward the first sheet guide, to locations beyond the guide surface formed by the first sheet guide. When a sheet is located between the first sheet guide and the protuberance of the second sheet guide, the protuberance extends at least a portion of the sheet toward the first sheet guide to bring a part of a surface of the sheet into contact with the first sheet guide.
Claims20
A sheet gripping mechanism comprising:
- a first sheet guide comprising a guide surface facing sheet conveyance path along which a sheet is to be conveyed;
- and
- a second sheet guide which faces the first sheet guide across the sheet conveyance path,
- wherein the second sheet guide includes a protuberance extending toward the first sheet guide to a location beyond the guide surface formed by the first sheet guide, whereby, when a sheet is located between the first sheet guide and the protuberance of the second sheet guide, the protuberance extends at least a portion of the sheet toward the first sheet guide to bring a part of a surface of the sheet into contact with the first sheet guide.
A printer comprising:
- a discharge port through which a sheet may be discharged;
- a printing unit configured to perform printing on a sheet to be discharged through the discharge port after printing on the sheet is completed;
- and
- a sheet gripping mechanism comprising a first sheet guide forming a guide surface which faces a sheet conveyance path, and a second sheet guide which faces the first sheet guide across the sheet conveyance path,
- wherein the second sheet guide includes a protuberance extending from the sheet conveyance path thereof beyond the guide surface of the first sheet guide, and
- wherein, when a sheet is located on the protuberance, the protuberance extends at least a portion of the sheet toward the first sheet guide to bring a part of the sheet into contact with a surface of the first sheet guide, and the sheet gripping mechanism is located in a sheet conveyance path between the printing unit and the discharge port and grips a sheet at a location inwardly of the discharge port.
A sheet gripping mechanism comprising:
- a first sheet guide forming a guide surface which faces a sheet conveyance path fora sheet, the guide surface including an opening extending thereinto, the opening having opposed sidewalls;
- and
- a second sheet guide which faces the first sheet guide across the sheet conveyance path, wherein
- the second sheet guide includes a protuberance protruding inwardly of the opening in the guide surface of the first sheet guide, spaced from the opposed sidewalls of the opening in the guide surface of the first sheet guide, and
- when a sheet is located between the first sheet guide and the protuberance of the second sheet guide, the protuberance extends at least a portion of the sheet inwardly of the opening and portions of the sheet contact the protuberance of the second sheet guide and the sidewalls of the opening extending into the guide surface of the first sheet guide.
