Specific embodiment

In order to more clearly describe the technical solution of the utility model, so that the technical solution of the utility model can be Those skilled in the art understands, below in conjunction with accompanying drawing, the specific embodiment of specific descriptions technical solutions of the utility model.

As illustrated in figures 4-5, this utility model roll sheet holder 10 includes guide 11, keeper axle 12, keeper 13.

Keeper axle 12 is substantially in open column shape, including first end 12a, the second end 12b and main part 12；Main part 12c is configured to polygonal column, can accommodate the roll of tape 9 on a hollow cylinder belt carcass；First end 12a is constructed For orthohexagonal protuberance, certainly, optionally, it is also possible to be configured to the shapes such as other regular polygons or circle, Two end 12b are configured to the protuberance of regular pentagon, certainly, optionally, it is also possible to be configured to other regular polygons or The diameter with diameter greater than main part 12c of the shapes such as circle, wherein first end 12a, the second end 12b with diameter greater than main body The diameter of portion 12c；Guide 11 includes an installing hole 11a, and the diameter of installing hole 11a is slightly larger than the diameter of main part 12c, from And guide 11 can pass through main part 12c and abut first end 12a, so as to guide 11 is spacing by first end 12a.It is fixed Position part 13 is attached on the second end 12b of main part 12c；The connection of keeper axle 12 guide 11 and keeper 13.Roll of tape 9 An end contact guide 11, another end contact keeper 13 of roll of tape 9.Keeper axle 12 accommodates roll of tape 9.

The printer being used together with this utility model roll of tape and roll sheet holder, with structure as shown in Figure 3, Printer includes housing 2, to accommodate each parts in printer；Top cover 3, in being as pivotally connected to housing 2 and can cover All parts in housing；Insertion opening 7, in roll of tape, unwound coil paper can be inserted into the insertion opening 7, and in printer mistake Journey is used to feed roll of tape, as shown by arrows in FIG. for paper roll feed direction, the direction is also defined as printer and roll of tape The width of keeper；Roll of tape receiving portion 4, for accommodating roll of tape and roll sheet holder, is formed as one to recessed Sunken recess；Limited impression 8, is formed as the guide in support roll sheet holder to position roll sheet holder；Keep Device supporting member 5, is formed in the side of printer housing, and is formed with the locating slot 6 of an opening upwards.

When roll of tape and roll sheet holder are attached in printer, the first location division 15 in guide 11 is inserted In limited impression 8 into printer, roll sheet holder is prevented to along feed direction vibration, the second positioning of guide 11 Support during portion 16 is connected to roll of tape receiving portion 4 and by roll of tape receiving portion 4, so as to support roll of tape to keep in above-below direction Device；It is spacing by which in the locating slot 6 of the insertion printer keeper of installed part 14 supporting member 5 in keeper 13, so as to roll of tape And roll sheet holder is stable being attached in printer and being supported by printer.

In the present embodiment, installed part 14 is arranged on the keeper 13 and from the outwardly protrusion shape of keeper 13 Become rib-like, the installed part 14 is symmetrical along its center line.When roll sheet holder is attached in printer, installed part 14 Slide along locating slot 6.When installed part 14 is attached in locating slot 6, the centrage of installed part 14 is big with the center of locating slot 6 Cause to overlap, so as to installed part 14 is housed stably in locating slot 6 and is supported.As shown in fig. 6-7, keeper 13 is along width The first side 13a and the second side 13b is respectively formed with direction.The central shaft of installed part 14 and the first side 13a of keeper away from From for L1, the central shaft of installed part 14 and the distance of the second side of keeper 13b are L2, and wherein L1 is more than L2.This utility model is pacified Piece installing 14 is closer to the second side 13b relative to the first side 13a of keeper 13.Selectively, installed part 14 can also be arranged Obtain the second side 13b closer to keeper.Support when roll sheet holder in the present embodiment is attached to keeper in printer In the locating slot 6 of part 5, installed part 14 is located at the center of locating slot 6 and is limited by the first locating slot 6；Simultaneously only keeper The first side 13a protrusions keeper supporting member 5 outside, and the second side 13b will not be protruded outside keeper supporter 5, so i.e. Protuberance is provided with making printing machine cap 3, also will not be interfered with roll sheet holder 10 and be affected the peace of roll sheet holder Dress.Compared to the roll sheet holder of prior art, roll sheet holder of the present utility model is smaller, using material more It is few, reduce production cost.But the positioning of functionally roll sheet holder is unaffected, and corresponding printer can be improved Design freedom.
