Structure to these base side unit 12 and lid side unit 13 is described in detail below.At first, base side unit 12 has this body frame 40, has set up balladeur train guidance axis 23 in the front part broad ways of this this body frame 40.On this balladeur train guidance axis 23, such as described, be supported with the head balladeur train 22 that has carried printhead 20 with the state that can move around.State with mulch-laying machine head carriage 22 and printhead 20 is equipped with colour band frame 41, and the outer peripheral portion of this colour band frame 41 is set as the installation portion 10 of ribbon cartridge 9.
Be formed for loading the incorporating section 8 of record paper roll 7 on the part of the rear side of this body frame 40, on the rear end part of this incorporating section 8, the rotary middle spindle 43 that broad ways is extended is erected on this body frame 40.This rotary middle spindle 43 becomes the center of rotation of covering side unit 13.
On the other hand, lid side unit 13 has cover framework 51, and this opens and closes the front end connecting plate part 54 that framework 51 has left and right sides transverse arm part 52,53 along the fore-and-aft direction extension, connects the fore-end of these transverse arm parts 52,53.The rear end part of left and right sides transverse arm part 52,53 by shown in the two end portions of rotary middle spindle 43 support freely to rotate.Front end in the front end connecting plate part 54 of covering framework 51 is equipped with lettering pressing plate frame 55, in its rear side paper feed roller axle 25a is installed, with the outer peripheral face of paper feed roller axle 25 along co-axially fixed 2 paper feed roller body 25b, 25b, the peristome 28a from the guide plate 28 that is formed at this lettering pressing plate frame 55 is forwards outstanding.On the front end connecting plate part 54 of lid framework 51, be equipped with the movable blade 32 and the driving mechanism 33 of scissor record-paper shearing device 30.
Here, can see that in this routine base side unit 12, as previously described, printhead 20 is tilted configuration upward from Fig. 2,3, corresponding with it, be installed in ribbon cartridge 9 in the installation portion 10 and also be configured to the state that tilts to same direction.In addition, in lid side unit 13 1 sides, according to the parallel at certain intervals relative mode of head face 20a with respect to printhead 20, square neck tiltedly disposes lettering pressing plate 21 down.In addition, the center of rotation of lid side unit 13, promptly the height and position of the central axis of rotary middle spindle 43 is set as the position of more leaning on downside than the head face 20a of printhead 20.
Consequently, be accompanied by the motion track of this lid side unit fore-end of the switching of covering side unit 13, promptly the upper end of the lettering pressing plate 21 relative with printhead 20 and the motion track of lower end are, from the position relative at certain intervals (lid side unit 13 is in the position of closed condition) with printhead 20, head face 20a with respect to printhead 20, be not forwards or the top, but rearward away from circular arc.So when lid side unit 13 opened and closed, lettering pressing plate 21 can not run into printhead 20.
In addition, the center of rotation (center of rotary middle spindle 43) of lid side unit 13 is owing to be positioned at the position of more leaning on downside than the head face 20a of printhead 20, therefore, the motion track at the two ends up and down of lettering pressing plate 21, it is bigger to be accompanied by the mobile and rearward amount of movement that covers side unit 13.Consequently, directly over print position 17, form the space (when when the side is seen, being the space of del) that can not intersect with the motion track of lid side unit 13.In this example, utilize this space, dispose platen 26, torsion bar 27, the fixed blade 31, cutter blades 35 etc. of cutting unit 30 automatically.So, can make device constitute densification.
In addition, in this example, in printhead 20 tilted configuration, the installation portion 10 of ribbon cartridge 9 also is tilted configuration.Consequently, ribbon cartridge 9 by from the place ahead upside of this installation portion 10 along oblique loading and unloading.Though directly over print position 17, dispose fixed blade 31, the cutter blades 35 of platen 26, automatic cutting unit 30,, can not be subjected to them to load and unload ribbon cartridge 9 intrusively.So the advantage that can carry out the loading and unloading of ribbon cartridge 9 by once-through operation is arranged.
And a side or both sides in the height and position of the angle of inclination by adjusting printhead 20 and lettering pressing plate 21 and the rotation centerline 43a of lid side unit 13 can change the motion track that covers side unit 13.Thus, have to increase and decrease directly over print position 17 space of not intersecting with the motion track of lettering pressing plate 21 that forms, increase the advantage of the free degree of part placement.
Below with reference to Fig. 7～Figure 10, the support structure of the fixed blade 31 on the scissor record-paper shearing device 30 of present embodiment is described.At first, the cylinder installing plate 29 of fixed blade 31 is installed, has the guide plate part 61 with guide plate 28 parallel array,, continuing horizontally extending horizontal plate portions 62 after the bending of printer the place ahead in the upper end of this guide plate part 61.In addition, at the front end of horizontal plate portions 62, the vertically extending vertical panel part 63 in crooked back is arranged upward, the upper end of this vertical panel part 63 continues horizontally extending cutter blades holding plate part 64 after the rear bending of oriented printer.The rear end part of this cutter blades holding plate part 64 is to the bending of oblique rear, in the upper end and the cut-out blade 35 formation one of this part.The cylinder installing plate 29 of this structure, the two ends of its horizontal plate portions 62 are set up in the upper part of the left and right sides rear side end plate portion 44,45 of the body unit 40 on the base side unit 12, and be fixing on these parts.
On the horizontal plate portions 62 of cylinder installing plate 29, leaf spring 91 is housed.In the present embodiment, the two ends of leaf spring 91 are fixed on the horizontal plate portions 62 by fixed screw 92a, 92b.Leaf spring 91 is formed by the crooked perk of the plate spring portion 91a, the 91b that extend towards oblique upper from about the mediad of its width.The plate spring portion 91a on both sides, 91b form with same length, but the height of the first end of perk is higher the plate spring portion 91a in left side one side.Supporting fixed blade 31 above the leaf spring 91 at this.
On the other hand, the two end portions from the end face of the printer front side of fixed blade 31 forms to printer the place ahead outstanding pair of right and left projection 31e, 31f.On the vertical component 63 of cylinder installing plate 29, be formed with the slit 63a, the 63b that insert these projections 31e, 31f.Jut 31e, 31f are towards front end one side thickness attenuate gradually.The width of corresponding slit 63a, 63b is certain.Thus, fixed blade 31 state that can rotate up and down with its blade 31a one side is installed on vertical panel part 63.
Here, the slit 63a in left side forms in the position higher than the slit 63b on right side.Thus, fixed blade 31 is installed on vertical panel part 63 with the heeling condition that tilts slightly towards the right side from the left side downwards.As mentioned above, because the left side plate spring portion 91a of leaf spring 91 is than the plate spring portion 91b height on right side, so whole fixed blade 31 is pushed to the top by certain spring force with the posture that tilts.
