The specific embodiment

Explain embodiment of the present utility model below in conjunction with accompanying drawing:

As shown in Figures 1 to 4, the utility model has disclosed a kind of portable printer, and it comprises shell 1, rubber roll transmission group 2, TPH(thermal printing head) and control element group 3, carbon ribbon transmission group 4, upper cover 5 and removable carbon ribbon group 6;

Described shell 1 is the rectangular housing of a strip, its top coordinates the upper cover 5 can opposite shell 1 opening, shell 1 forms chamber resettling with upper cover 5, two ends at shell 1 arrange electrical accessorie, as power supply, wiring board and motor etc., (this is the electric elements of printer indispensability, non-this case emphasis, does not describe in detail at this).In the chamber forming at shell 1 and upper cover 5, left end is that rubber roll transmission group 2 is set, right-hand member is that carbon ribbon transmission group 4 is set, rubber roll transmission group 2 and carbon ribbon transmission group 4 is common forms two tops open first hemi-closure space 11 that can hold carbon ribbon group 6 and the second hemi-closure space 12, and TPH and control element group 3 are to be just arranged between the first semiclosed appearance 11 and second between hemi-closure space 12.

Described upper cover 5 is provided with rubber roll 51, and after upper cover 5 fastens with shell 1, rubber roll 51 just bears down on one at TPH(thermal printing head) and the position of the TPH31 of control element group 3.After upper cover 5 fastens with shell 1, its front and back end and shell 1 just form paper feed port 14 and exit slot 15.Between upper cover 5 and shell 1, coordinate by buckle is movable, release knob 13 can be arranged on shell 1.

Described TPH(thermal printing head) and control element group 3 comprise TPH31 and mainboard 32.

Described carbon ribbon transmission group 4 comprises the first carbon ribbon swivel head 41 coordinating with carbon ribbon backrush axle 63 and the second carbon ribbon swivel head 42 coordinating with carbon ribbon mandrel 61.

Described carbon ribbon group 6 comprises support 60 and is engaged in a carbon ribbon mandrel 61, carbon ribbon backrush axle 63 and the carbon ribbon film 62 on support 60, and carbon ribbon film 62 one end are wound on carbon ribbon mandrel 61, and the other end is bonded on carbon ribbon backrush axle 63.

When the concrete implementation of printer of the present utility model, open upper cover group 5, carbon ribbon group 6 is matched with in shell 1, be that carbon ribbon group 6 is assembled in the first hemi-closure space 11 and the second hemi-closure space 12 from the opening on top, wherein, carbon ribbon mandrel 61 in carbon ribbon group 6 is in the second hemi-closure space 12, carbon ribbon backrush axle 63 is in the first hemi-closure space 11, carbon ribbon film 62 in carbon ribbon group 6 covers TPH and control element group 3 tops, carbon ribbon backrush axle 63 is connected with carbon ribbon transmission group 4 by the first carbon ribbon swivel head 41, carbon ribbon mandrel 61 is connected with carbon ribbon transmission group 4 by the second carbon ribbon swivel head 42.

When printer work, upper cover group 5 closures, the rubber roll 51 in upper cover group 5 is pressed on TPH(thermal printing head) 31 top, sandwich carbon ribbon film 62, carbon ribbon film 62 is plastic sheetings that one deck one side is coated with carbon dust, is now the one sides that scribble carbon dust towards the one side of rubber roll 51.Coordinate shown in Fig. 4, when paper 7 one end are put into printer and arrived rubber roll 51 and TPH(thermal printing head from printer paper feed port 14) when 31 tangent position A, rubber roll transmission group 2 on printer is started working, and drive counterclockwise rotation of rubber roll 51, under the frictional force effect that paper 7 provides at rubber roll 51, move to exit slot 15.Now, be down paper 8 successively from rubber roll 51, carbon ribbon film 62 and TPH(thermal printing head) 31.When paper 7 moves to exit slot 15, friction drives carbon ribbon film 62 movement of turning right.When rubber roll transmission group 2 is started working, carbon ribbon transmission group 4 is also started working, and drives carbon ribbon backrush axle 63 by illustrating turning clockwise of 4 marks, and the carbon ribbon film 62 toward moving right is wound on carbon ribbon backrush axle 63.In the time that printer receives the data that need printing, TPH(thermal printing head) 31 under the control of mainboard 32, start heating, carbon ribbon film 62 is subject to thermal softening, under the pressure-acting that the carbon dust applying on film provides at heat and rubber roll 51, be attached on the paper 7 of carbon ribbon film 62 tops, thus by data-printing on paper 7.

In sum, portable printer of the present utility model, by being set respectively at shell 1 two ends, rubber roll transmission group 2 and carbon ribbon transmission group 4 form the first hemi-closure space 11 and the second hemi-closure space 12 that coordinate for carbon ribbon group 6, and TPH and control element group 3 are just arranged between the first semiclosed appearance to 11 and second between hemi-closure space 12, the portable printer compact conformation so forming, effectively reduced volume, realizes portable function, realizes the demand of printing anywhere or anytime; Utilize in addition carbon ribbon group 6 to print and be not only applicable to heat-sensitive paper, but also go for plain paper, and the writing holding time is long, applicable to long-term file printout of preserving.
