Detailed description of the invention
With reference to Fig. 1 ~ Fig. 6, a kind of printer upper guide plate assembly routed up of the present invention, it comprises upper guide plate 1 and left and right side frame 2,3, before and after described left and right side frame 2,3 liang of relative sidewalls are respectively arranged with towards left long guide groove 21, right long guide groove 31, the front and back at this place extend towards referring to the paper direction of leading of left and right guide groove 21,31 along printer, printer lead paper direction as shown in the arrow A in Fig. 1, upper guide plate 1 is shelved in left and right long guide groove 21,31 by the rotating shaft 11 at its two ends; The left and right sides wall of described upper guide plate 1 is also provided with front fulcrum 12, front fulcrum 12 is snapped with extension spring 4, preferred described front fulcrum 12 is provided with the annular groove 121 for shelving extension spring 4, prevent extension spring 4 from coming off, the other end of extension spring 4 being positioned at left side snaps onto on left frame 2 on corresponding button bit, and the other end of the extension spring 4 on the right side of being positioned to snap onto in left side frame 3 on corresponding button bit; Described left and right long guide groove 21,31 is respectively one away from the outer face of printhead 6 and adapts to the left and right cambered surface 22,32 that front fulcrum 12 is center of rotation with rotating shaft 11; Adapt to front fulcrum 12 by rotating shaft 11 for center of rotation refers to when front fulcrum 12 rotates centered by rotating shaft 11, left and right cambered surface 22,32 makes way for front fulcrum 12, and the lower position of left and right cambered surface 22,32 is respectively the suitable left and right draw-in groove of the same fulcrum 12 23,33.When printer is in normal operating conditions, front fulcrum 12 makes upper guide plate 1 have the trend of moving towards printhead 6 all the time under the effect of extension spring 4, rotating shaft 11 is connected to left and right long guide groove 21,31 on the inner face of printhead 4, as shown in state 1b in Fig. 5, now, upper guide plate 1 is the narrowest with the distance of word car 5, what make the distance between upper guide plate 1 and printhead 6 become very is little, thus making printer when leading paper, the top of form of turnup can not be touched with printhead 6 and paper jam phenomenon occur.
When printhead 6 changed by needs, when colour band 7 or other reasons cause paper jam phenomenon and need remove paper jam error, with hand by upper guide plate 1 to the direction push-and-pull away from printhead 6, as the arrow indication in Fig. 5 represented by label c, make upper guide plate 1 move to rotating shaft 11 away from printhead 6 and be resisted against a left side, right long guide groove 21, on 31 inner faces away from printhead 6, then gently upper guide plate 1 is upwards routed up, as the curved arrow indication in Fig. 5 represented by label d, front fulcrum 12 is made to walk around a left side, right cambered surface 22, a left side is connected to after 23, right draw-in groove 23, in 33, upper guide plate 1 arrives as the state 1a in Fig. 5, namely as shown in Figure 6, now, very large spacing is had between upper guide plate 1 and word car 5, greatly facilitate the replacing to printhead 6 and colour band 7, and the removal to paper jam error.
When needs reset upper guide plate 1, only need light by upper guide plate 1 to the direction push-and-pull away from printhead 6, make front fulcrum 12 away from left and right draw-in groove 23,33, upper guide plate 1 just can automatically reset under the effect of extension spring 4, fast easy and convenient.
Affect and lead paper action for avoiding upper guide plate 1, when paper work led by printer, upset occurs, the left and right sides wall of described upper guide plate 1 is also provided with rear fulcrum 13, left, left side frame 2, 3 liang of relative sidewalls are respectively arranged with the left side stoping upper guide plate 1 to overturn, right deep-slotted chip breaker 24, 34, left, right deep-slotted chip breaker 24, the opening direction of 34 is towards rear fulcrum 13, printer is when normal operating conditions, rear fulcrum 13 snaps onto a left side, right deep-slotted chip breaker 24, in 34, left, right deep-slotted chip breaker 24, after 34 pairs, fulcrum 13 serves position-limiting action vertical, upper guide plate 1 is avoided to occur upset, guarantee that printer is led paper action and normally carried out.
For making when upper guide plate 1 resets, rear fulcrum 13 can drop in left and right deep-slotted chip breaker 24,34 all the time accurately, the upper groove of described left and right deep-slotted chip breaker 24,34 is along being connected to left and right support plate 25,35, and left and right support plate 25,35 plays the guide effect imported to by rear fulcrum 13 in left and right deep-slotted chip breaker 24,34.
As the improvement of above-mentioned embodiment, the left and right sides wall of described upper guide plate 1 is provided with the plate muscle 14 connecting forward and backward fulcrum 12,13.Consider that upper guide plate 1 and front fulcrum 12 are one-body molded for working of plastics, after long-time use, front fulcrum 12 may occur bending and deformation under the effect of extension spring 4, for improving the intensity of front fulcrum 12, extend its service life, can arrange the plate muscle 14 connecting forward and backward fulcrum 12,13 on the left and right sides wall of described upper guide plate 1, after avoiding long-time use, front fulcrum 12 deforms and even ruptures.
The above, just better embodiment of the present invention, but the present invention is not limited to above-described embodiment, as long as it reaches technique effect of the present invention with any same or similar means, all should fall within protection scope of the present invention.
