Label declaration:
The specific embodiment
By specifying technology contents of the present invention, structural feature, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 2, if use large diameter paper roll, the space of the maximum that paper roll can occupy promptly contacts with containing cavity cover cavity surface; Therefore of Fig. 2, if the containing cavity lid is a monoblock type chamber lid, might put into paper roll so after; Can't close the containing cavity lid, its reason is as shown in Figure 2, because reel diameter is excessive; Near or applying containing cavity cover cavity surface, therefore when covering the containing cavity lid, the terminal A 1 of the movable end that containing cavity covers contacts with paper roll; Thereby the containing cavity lid is interfered with the paper roll surface, cause the containing cavity lid to close.
Present embodiment provides a kind of handheld POS terminal; Be specially and comprise printing mechanism 2, casing 1; Said casing 1 is provided with containing cavity 11, and the opening part of containing cavity is provided with the containing cavity lid 12 hinged with casing, and containing cavity lid 12 surrounds a containing cavity cover cavity 13; Containing cavity cover cavity 13 openings are towards containing cavity 11, the space that containing cavity cover cavity 13 and containing cavity 11 together are formed for placing web-like print media 4;
Said containing cavity lid is joined end to end by the cover plate more than two successively, and hinged forming is hinged with cover plate one end and casing that casing is hinged, and the other end and adjacent cover plate are hinged; For example in the handheld POS terminal shown in Fig. 1 a～c, cover plate A121 and cover plate B122 are through jointed shaft 123 hinged formation, and cover plate A122 and casing 1 are hinged through jointed shaft 124 simultaneously.
Make the cross section of containing cavity lid along the perpendicular direction of jointed shaft between containing cavity lid and the housing; The intersection point of jointed shaft between contact point between cover plate and the casing and cover plate and the cover plate on cross section is called contact; Relation below contact satisfies: on the cross section, arbitrary contact to the distance of adjacent contact greater than this contact any any distance to the containing cavity cover cavity surface between this contact and the adjacent contact.
Be that 2 embodiment explains operation of the present invention with cover plate quantity now, the electronic equipment of present embodiment is behind the large diameter paper roll of packing into, when covering the containing cavity lid; Because between the cover plate is hinged relationship, therefore, can rotate relatively around jointed shaft between the adjacent cover plate; Referring to Fig. 3, when closing the containing cavity lid, earlier first cover plate (cover plate hinged with casing) and second cover plate (cover plate hinged with first cover plate) are opened; The two angle is increased; Then first cover plate is covered downwards,, therefore can not disturb moving downward of first cover plate because second cover plate becomes bigger angle with first cover plate.Then, as shown in Figure 4, we are downward with second cover plate again, accomplish closing of whole containing cavity lid.
It should be noted that contact satisfy below relation: on the cross section, arbitrary contact to the distance of adjacent contact greater than this contact any any distance to the containing cavity cover cavity surface between this contact and the adjacent contact.For example in Fig. 3; With contact P1 is example; Contact P1 to contact P2 apart from l1 greater than contact P1 to the containing cavity cover cavity surface between contact P1 and the contact P2 any 1 N1 apart from m1; With contact P2 is example, and contact P2 satisfies above-mentioned relation to contact P1's apart from l1 too, and simultaneously contact P2 to contact P3 apart from l2 greater than contact P2 to the containing cavity cover cavity surface between contact P2 and the contact P3 any 1 N2 apart from m2.
Because the position that N1 or N2 are the paper roll maximum possible to be arrived, if therefore l1 greater than m1 or l2 greater than m2, even can guarantee that like this paper roll has arrived its maximum position, that can guarantee that also contact turns over paper roll smoothly under hinged relationship, be unlikely to be stuck.
As opposite example; We are with reference to all-in-one-piece containing cavity lid design shown in Figure 2; Contact P5 to contact P6 apart from l6 less than contact P5 to some N5 apart from m5, some N5 is contact P5 to the containing cavity cover cavity surface between contact P5 and the contact P6 more arbitrarily.Therefore, during paper roll size point of arrival N5, contact P6 can't walk around paper roll.
It is 2 example that present embodiment has been enumerated the cover plate number, but in fact the cover plate number can be realized identical effect with reference to the present invention program more than or equal to 2.
Except the handheld POS terminal that present embodiment is enumerated, scheme of the present invention can also be applicable to that other have the hand-hold electronic equipments of printing function, or non-hand-hold electronic equipments.
In the present embodiment, local or whole surface of said containing cavity cover cavity is the part of internal surface of column, and the radian of the internal surface of column on arbitrary cover plate is less than or equal to π, and said containing cavity part or whole surfaces are the part of internal surface of column.But, be designed to other curved surface pattern, for example ellipsoid also is fine, but the face of cylinder relatively suits the common shape of paper roll, reaches best space availability ratio.
In the present embodiment; Articulated manner between the said cover plate is specially: in two cover plate joints; One end of one cover plate is provided with two convexities, two convexities on the jointed shaft between the cover plate and protrusion direction opposite, an end of another cover plate is provided with two shrinkage pools or through hole; Said shrinkage pool or through hole and said convexity are suitable, and said convexity snaps in shrinkage pool or the through hole.But adopt the end that joins of adjacent coverslips that through hole is set, carry out hinged other modes that wait through the mode of a rotating shaft that runs through then and also be fine.
Wherein, Said printing mechanism is a thermal printing mechanism, and printing mechanism is provided with printhead 31, drive unit and live-roller 32, and said printhead 31 is arranged in containing cavity 11; Said driving mechanism is provided with the driven wheel of output rotating torque; Said live-roller 32 is connected with containing cavity lid 12, and live-roller one end is provided with driven gear 321, and driven gear drives live-roller 32 rotations;
Said containing cavity lid 12 and casing 1 movable the fastening, during fastening, live-roller 32 can press print media between the two with printhead 31, and driven gear 321 is meshed with driven wheel simultaneously.
Wherein, said live-roller 32 comprises roll body, be arranged in roll shaft 322 in the roll body, be arranged at the roll shaft bearing at roll body two ends, and said driven gear is arranged at the roll shaft bearing outside,
