In the present invention, the idler gear of wherein said Power Drive Unit and the engagement of all change owner moving gears, this switches driving gear and switches the coaxial interlock of hypodontia gear with one, a part of circumference of described switching hypodontia gear is provided with tooth and is meshed with the tooth of operating rocker wheel, on this operating rocker wheel, be provided with projection, one state switches driving wheel and is meshed with a back friction roller gear by projection, this state switches driving wheel and the coaxial interlock of a state change gear, this state change gear and described continuous media drag the paper device driven gear that drags of paper device to mesh, on described operating rocker wheel, be provided with the knob spring that resets, therefore driving the crop rotation of switching driving tooth when the Power Drive Unit rotation clockwise rotates, owing to switch driving gear and switch the coaxial interlock of hypodontia gear, switch the hypodontia gear and also clockwise rotate this moment, switch the hypodontia gear clockwise after certain angle its tooth be meshed with the tooth that operating rocker is taken turns, this moment, the operating rocker wheel rotated counterclockwise, the protruding jack-up state that this moment, operating rocker was taken turns switches driving wheel, state switches the driving wheel rising and is meshed with back friction roller gear, thereby the drive state switches driving wheel to rotate, further drive state change gear is rotated, owing to drag the engagement of paper device driven gear and state change gear, realized that the drive continuous media drags the work of paper device so drag paper device driven gear to rotate, promptly entered the continuous media duty, promptly realized switching to the work of continuous media from single medium; Driving the crop rotation of switching driving tooth when the Power Drive Unit rotation rotates counterclockwise, switch the hypodontia gear and rotate counterclockwise this moment, its tooth is meshed with the tooth of operating rocker wheel after switching the hypodontia gear to reverse certain angle, this moment, the operating rocker wheel clockwise rotated, thereby the projection that drives on it moves, state switching driving wheel descends under the effect of the knob spring that resets and separates with back friction roller gear, thereby enter the single medium state, realized switching to single medium from continuous media, so the present invention is owing to adopted said structure, so its low cost of manufacture, it is little to take up room, and can realize the continuous media of printer and the automatic switchover between the single medium.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of the device of the continuous media of a kind of printer that can automatically switch of the present invention and single medium.
Fig. 2 is the structure chart of operating rocker wheel of the device of the continuous media of a kind of printer that can automatically switch of the present invention and single medium.
The specific embodiment
As shown in Figure 1, it is a structural representation of the present invention.A kind of continuous media of printer and device of single medium of can automaticallying switch, comprise that Power Drive Unit 1 and continuous media drag paper device 15, this continuous media drags paper device 15 to have to drag paper device driven gear 14, wherein this to drag paper device driven gear 14 are square shaft gears.In the technical program, Power Drive Unit 1 comprises motor 2, deceleration strip moving gear 3, reduction gearing 4, idler gear 5, the gear of described motor 2 and 3 engagements of described deceleration strip moving gear, described deceleration strip moving gear 3 and reduction gearing 4 coaxial interlocks, described reduction gearing 4 and idler gear 5 engagements, described idler gear 5 and all change owner moving gear 6 engagements, this switches driving gear 6 and and switches hypodontia gear 7 coaxial interlocks, a part of circumference of described switching hypodontia gear 7 is provided with tooth and is meshed with the tooth of operating rocker wheel 8, promptly its tooth is meshed with the tooth of operating rocker wheel 8 in these switching hypodontia gear 7 rotation processes, this operating rocker wheel 8 is sectional wheels, on this operating rocker wheel 8, be provided with projection 9, see Fig. 2, this projection 9 is oblique projectioies, one state switches driving wheel 10 and is meshed with a back friction roller gear 12 after by protruding 9 jack-up, described state switches driving wheel 10 and a state change gear 11 coaxial interlocks, drag paper device driven gear 14 and described state change gear 11 engagements, be provided with the knob spring 13 that resets on described operating rocker wheel 8, this effect that resets knob spring 13 is to make operating rocker wheel 8 to reset and is fixing.
When the present invention uses, at first, the process that switches to continuous media from single medium is: motor 2 work and drive its gear and rotate counterclockwise, deceleration strip moving gear 3 clockwise rotates at this moment, because deceleration strip moving gear 3 and reduction gearing 4 coaxial interlocks, so reduction gearing 4 also clockwise rotates, thereby driving idler gear 5 rotates counterclockwise, because idler gear 5 and 6 engagements of switching driving gear, so switching driving gear 6 clockwise rotates, owing to switch driving gear 6 and switch hypodontia gear 7 coaxial interlocks, so switching hypodontia gear 7 clockwise rotates, switch hypodontia gear 7 clockwise after certain angle its tooth and operating rocker take turns 8 tooth and be meshed, operating rocker wheel 8 rotates counterclockwise at this moment, the projection 9 jack-up states that this moment, operating rocker was taken turns on 8 switch driving wheel 10, state switches driving wheel 10 risings and is meshed with back friction roller gear 12, thereby the drive state switches driving wheel 10 to rotate, because state switches driving wheel 10 and state change gear 11 coaxial interlocks, so state change gear 11 is rotated, owing to drag paper device driven gear 14 and 11 engagements of state change gear, so drag paper device driven gear 14 to rotate, promptly realize driving described continuous media and dragged 15 work of paper device, promptly entered the continuous media duty, realized that printer switches to the work of continuous media from single medium; Secondly, the process that continuous media switches to single medium is: motor 2 work and drive its gear and clockwise rotate, deceleration strip moving gear 3 rotates counterclockwise at this moment, because deceleration strip moving gear 3 and reduction gearing 4 coaxial interlocks, so reduction gearing 4 also rotates counterclockwise, thereby driving idler gear 5 clockwise rotates, because idler gear 5 and 6 engagements of switching driving gear, so switching driving gear 6 rotates counterclockwise, wherein switching driving gear 6 rotates counterclockwise certain angle and will stop, so the present invention does not have to interfere and produces, owing to switch driving gear 6 and switch hypodontia gear 7 coaxial interlocks, so switching hypodontia gear 7 rotates counterclockwise, its tooth is meshed with the tooth of operating rocker wheel 8 after switching hypodontia gear 7 to reverse certain angle, operating rocker wheel 8 clockwise rotates at this moment, thereby the projection 9 that drives on it moves, state switching driving wheel 10 descends under the effect of the knob spring 13 that resets and separates with back friction roller gear 12, thereby enter the single medium state, realized that printer switches to single medium from continuous media.
In a word,, should illustrate that obviously those skilled in the art can carry out various variations and remodeling though the present invention has exemplified above-mentioned preferred implementation.Therefore, unless such variation and remodeling have departed from scope of the present invention, otherwise all should be included within protection scope of the present invention.
