The arc surface approximate right angle ground butt of the arc surface of upwardly extending formation fulcrum 22 and formation head axle 23 is a contact in front and back.Thus, the headstock 34 and thermal head 19 can be fulcrum with fulcrum 22, are moving on the following direction with freely swinging: the direction that thermal head 19 is pressed into the direction on the reel 17 and the power of pushing on the length direction of thermal head 19 is regulated.
As shown in Figure 3, an axis hole 24 is slotted holes longitudinally, and lateral dimension is roughly the same with the outside dimension of head axle 23.Therefore, as the action of the headstock 34, the direction action in addition that restriction is pressed into thermal head 19 direction on the reel 17 and the power of pushing on the length direction of thermal head 19 is regulated.
Fig. 6 overlooks the figure that observes the headstock 34.
Can find out clearly that from this figure the central point 38 of the length direction of thermal head 19, above-mentioned fulcrum 22 and spring supporting frame collude hanging hole (force of spring 27) 25, general alignment lists one under the observation overlooking.In other words, the structure of employing is: making above-mentioned fulcrum 22 be positioned at the line L1 between the two ends that link thermal head 19 is on the summit Q of isosceles triangle on base; Spring supporting frame is colluded on the line L2 that hanging hole 25 is positioned at the center R (central point 38) that links this fulcrum 22 and base.In this structure, because the spring force of spring 27 almost acts on the central point 38 of the length direction of thermal head 19 reliably, so on the length direction of thermal head 19, can correctly apply pressing force for reel about 17 equalizations.
Since by this overlook under observing with thermal head 19 binary points, with the position configuration fulcrum 22 of thermal head 19 quadratures and the force of spring 27, and is to freely swing about fulcrum by a long axis hole 24 thermal heads 19 with fulcrum 22, therefore, freely move on the direction that the power that the headstock 34 and thermal head 19 are pushed on to the length direction about thermal head 19 is regulated, thermal head 19 is pushed reel 17 equably on the periphery contraposition ground of reel 17.
This reel 17 as mentioned above, is pushed by bearing portion 35 under the situation about being positioned by thermal head 19 in the spool shaft 15 of reel 17, because of the precision of bearing portion 35, may cause the situation that reel 17 tilts and installs at its axis direction.Even in this case, according to this structure, because thermal head 19 cooperates the position of reels 17 and is pressed into equably on the reel 17, thus also can improve the compactness of thermal head 19 and reel 17, thus registration accuracy can be improved.
In this structure, the support plate of thermal head extends to the rear position of the top of coil paper 40, in this extension rear end, be provided with the force that is used for thermal head is pressed into the force application mechanism on the reel, and, because force application mechanism is disposed at above web-taking in device the spatial portion in the bight that the inside, the periphery track by coil paper 40 form, so, needn't be reset at thermal head 19 and put on the shelf and be used to dispose the space of force application mechanism between 7, thus put on the shelf 7 height of lowland restriction very.Therefore, can provide the printer of miniaturization, and this printer can be disposed at simply on low shelf of the following height of the sales counter in shop etc. for example etc.In addition, because the central point of thermal head, the fulcrum that support plate is swung, the force of force application mechanism, be positioned on the imaginary plane with the length direction approximate vertical of thermal head, so the load distribution in the longitudinal direction that can make thermal head put on reel becomes even.
More than, based on an embodiment the present invention has been described, but the present invention is not limited thereto.For example, in the above-described embodiment, the headstock 34 constitutes by 23 contacting structure of circular-arc fulcrum 22 and head axle, but be not limited thereto, so long as thermal head 19 is pressed into the direction of reel 17 and to the direction of regulating in the power of pushing on the length direction of thermal head 19 on, the structure that the headstock 34 can freely be swung, then this contact supporting construction can be other any structures.
