Abstract
An opening and closing mechanism is provided in a printing device, such as a printer which utilizes fan-folded print sheet fed between a pair of sheet dust brushes, wherein the mechanism separates the pair of brushes when a cover, panel or so forth is opened. The separation of the pair of brushes makes it easy to set the fan-folded sheet, or to remove jammed sheets since the brushes are separated when the cover, panel or so forth is opened.
Claims9
An opening and closing mechanism for a sheet printing device comprising:
- a pair of sheet dust brushes;
- a brush housing including a pair of brush housing portions, said pair of sheet dust brushes each being located in one of said brush housing portions, said pair of brush housing portions being movable between a first position in which said pair of sheet dust brushes are in contact with each other, and a second position in which said pair of sheet dust brushes are separated from each other;
- and
- at least one of said brush housing portions being coupled to a predetermined portion of said printing device so as to be movable with respect to said predetermined portion, said predetermined portion being movable between and opened and closed position, said at least one of said brush housing portions being movable to said second position when said predetermined portion is moved to said opened position.
An apparatus for moving a pair of sheet dust brushes between two positions, said apparatus being adapted to be positioned in a device which utilizes at least fan-folded sheet such that said fan-folded sheet is fed between said pair of sheet dust brushes, said apparatus comprising:
- means for moving said pair of sheet dust brushes between a first position where said pair of sheet dust brushes are in contact, and a second position where said pair of sheet dust brushes are separated by a predetermined angular distance;
- means for biasing said pair of sheet dust brushes toward said first position;
- means for biasing said pair of sheet dust brushes toward said second position;
- said pair of sheet dust brushes being housed in a brush holder, said brush holder comprising pivotable attached sections, each of said sections housing one sheet dust brush of said pair of sheet dust brushes, said brush holder being biased toward said first position;
- and
- said means for moving including a lever assembly, said lever assembly including at least one operation arm with one end in contact with a movable member which moves corresponding to said first position and said second position, and another end in contact with one of said sections of said brush holder, said at least one operation arm being pivotally attached to said device.
