摘要： A spherically particulate toner characterized by a volume-average particle diameter of from 1 to 6 &mgr;m, a colorant content of not less than 9.1% by weight, particularly not less than 5% by weight when the colorant is an organic chromatic pigment, based on the total weight of the binder resin and colorant used and an average circularity (average of circularity defined by (perimeter of circle having the same area as the projected area of particle)/(perimeter of the projected image of particle)) of not less than 0.98. The spherically particulate toner according to the present invention gives an excellent image quality and can be consumed in a drastically reduced amount per sheet of printing paper. By predetermining the particle size distribution of spherical toner particles and the added amount of inorganic oxide fine particles to optimum values, the image quality can be further improved.

摘要： The mechanism for opening and closing an operating cover of a printer having a discharge guide that remains in the same posture while moving in conjunction with opening and closing the operating cover prevents the gap between the discharge guide and the cover case of the operating cover from widening when the operating cover opens and closes. In a roll paper printer 1, the top end part 32a of the cover case 32 of an operating cover 3 is pivotably attached on the side of the discharge guide 5, which remains in the same posture while moving in conjunction with the cover 3 opening and closing. So that the cover case 32 does not separate from the cover frame 31 when the cover 3 opens and closes, a torsion spring 37 constantly urges the cover case 32 to open and close in unison with the cover frame 31 through an intervening connector arm 34. When the cover 3 opens and closes, a large gap is not formed between the top end part 32a of the cover case 32 and the discharge guide 5, and this gap does not increase in conjunction with the cover 3 opening and closing.

摘要： Disclosed is a printer comprising a paper guide surface (11D) defining a printing region. A print head (8) is disposed opposite to the paper guide surface (11D) with a gap in between and adapted to move in parallel to the paper guide surface (11D) along the printing region (11) and beyond the printing region (11) into a retracted position (11C). A paper guide guides recording paper (5) to the printing region (11) and exposing it to the print head (8) in the printing region. The paper guide includes a guide plate (31) movable between a first position in which it is disposed opposite to the paper guide surface (11D) so as to guide recording paper (5) past the printing region (11), and a second position in which it is retracted from the printing region. A drive source (31-38) moves the guide plate (31) from the first to the second position only when the print head (8) is in the retracted position (11C).

摘要： A cutter and a printer having a cutter prevent the paper pieces cut off by the cutter from collecting at the paper exit from which the cut-off pieces are discharged. A stage surface 40defines the bottom edge 5a of the paper exit 5. A sloped guide surface 41 is formed sloping down from the downstream side of the stage surface 40. A first side wall 42 determines where one side of the width of the paper passes over the stage surface 40 and the sloped guide surface 41. A second side wall 43 determines where the other side of the width of the paper passes. A protrusion 47 is formed on the first side wall 42 protruding toward the second side wall 43.When label paper 11 is cut, the cut-off portion 11c is deposited on the stage surface 40 covering the top of the protrusion 47. As a result, the cut-off portion 11c is made unstable by the protrusion 47 immediately after being deposited on the stage surface 40, and slides down easily. The cut-off portion 11c slides down from the stage surface 40 along the sloped guide surface 41, and is discharged smoothly from the paper exit 5.
