The specific embodiment
By describing technology contents of the present invention, structural feature in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 2, if apply large diameter paper roll, the maximum space that paper roll can occupy contacts with accommodating cavity cover cavity surface, therefore as described in Figure 2, if accommodating cavity lid is a monoblock type chamber lid, so likely put into after paper roll, cannot close accommodating cavity lid, its reason as shown in Figure 2, because reel diameter is excessive, approaches or laminating accommodating cavity cover cavity surface, therefore in the time covering accommodating cavity lid, the terminal A 1 of the movable end of accommodating cavity lid contacts with paper roll, thereby accommodating cavity lid and paper roll surface are interfered, and causes accommodating cavity lid to close.
The present embodiment provides a kind of handheld POS terminal, be specially and comprise printing mechanism 2, casing 1, described casing 1 is provided with accommodating cavity 11, the opening part of accommodating cavity is provided with the accommodating cavity lid 12 hinged with casing, accommodating cavity lid 12 surrounds an accommodating cavity cover cavity 13, accommodating cavity cover cavity 13 openings are towards accommodating cavity 11, the space that accommodating cavity cover cavity 13 and accommodating cavity 11 are together formed for placing web-like print media 4;
Described accommodating cavity lid is joined end to end successively by two above cover plates, 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 by the hinged formation of jointed shaft 123, and cover plate A122 and casing 1 are hinged by jointed shaft 124 simultaneously.
Make the cross section of accommodating cavity lid along the perpendicular direction of jointed shaft between accommodating cavity lid and housing, the intersection point of jointed shaft between contact point between cover plate and casing and cover plate and cover plate on cross section is called contact, contact meets following relation: on cross section, arbitrary contact is greater than the distance of this contact to any point on the accommodating cavity cover cavity surface between this contact and adjacent contact to the distance of adjacent contact.
Now take cover plate quantity as 2 embodiment, operation of the present invention is described, the electronic equipment of the present embodiment is packing into after large diameter paper roll, in the time covering accommodating cavity lid, owing to being hinged relationship between cover plate, therefore, between adjacent cover plate, can relatively rotate around jointed shaft, referring to Fig. 3, in the time closing accommodating cavity lid, first the first cover plate (cover plate hinged with casing) and the second cover plate (cover plate hinged with the first cover plate) are opened, the two angle is increased, then the first cover plate is covered downwards, because the second cover plate has become larger angle with the first cover plate, therefore can not disturb moving downward of the first cover plate.Then, as shown in Figure 4, we by downward the second cover plate, complete closing of whole accommodating cavity lid again.
It should be noted that contact meets following relation: on cross section, arbitrary contact is greater than the distance of this contact to any point on the accommodating cavity cover cavity surface between this contact and adjacent contact to the distance of adjacent contact.For example, in Fig. 3, take contact P1 as example, contact P1 is greater than the distance m1 of contact P1 to any point N1 on accommodating cavity cover cavity surface between contact P1 and contact P2 to the distance l1 of contact P2, take contact P2 as example, contact P2 meets above-mentioned relation too to the distance l1 of contact P1, and simultaneously contact P2 is greater than the distance m2 of contact P2 to any point N2 on accommodating cavity cover cavity surface between contact P2 and contact P3 to the distance l2 of contact P3.
Because N1 or N2 are the positions that paper roll maximum possible arrives, if therefore l1 is greater than m1 or l2 is greater than m2, even if can guarantee that like this paper roll has arrived its maximum position, that also can guarantee that contact turns over smoothly paper roll under hinged relationship, is unlikely to be stuck.
As contrary example, we are with reference to all-in-one-piece accommodating cavity lid design shown in Fig. 2, contact P5 is less than the distance m5 of contact P5 to some N5 to the distance l6 of contact P6, and some N5 is contact P5 to any point on accommodating cavity cover cavity surface between contact P5 and contact P6.Therefore,, when paper roll size point of arrival N5, contact P6 cannot walk around paper roll.
The present embodiment has been enumerated the example that cover plate number is 2, but in fact cover plate number is more than or equal to 2 and can realizes identical effect with reference to the present invention program.
Except the handheld POS terminal that the present embodiment is enumerated, the solution of the present invention can also be applicable to other and have the hand-hold electronic equipments of printing function, or non-hand-hold electronic equipments.
In the present embodiment, the part of described accommodating cavity cover cavity or the part that whole surfaces is internal surface of column, the radian of the internal surface of column on arbitrary cover plate is less than or equal to π, the part that described accommodating cavity is local or whole surfaces is internal surface of column.But, be designed to other curved surface pattern, for example ellipsoid is also 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 described cover plate is specially: in two cover plate joints, one end of one cover plate is provided with two projections, two projections on the jointed shaft between cover plate and protrusion direction contrary, one end of another cover plate is provided with two shrinkage pools or through hole, described shrinkage pool or through hole and described projection are suitable, and described projection snaps in shrinkage pool or through hole.But adopt the end that joins of adjacent coverslips that through hole is set, then carry out hinged other modes such as grade by the mode of a rotating shaft running through and be also fine.
Wherein, described printing mechanism is thermal printing mechanism, printing mechanism is provided with printhead 31, drive unit and live-roller 32, described printhead 31 is arranged in accommodating cavity 11, described driving mechanism is provided with the driven wheel of output rotating torque, described live-roller 32 is connected with accommodating cavity lid 12, and live-roller one end is provided with driven gear 321, and driven gear drives live-roller 32 to rotate;
Described accommodating cavity lid 12 and casing 1 activity button-fold, when 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, described live-roller 32 comprises roll body, be arranged in roll shaft 322 in roll body, be arranged at the roll shaft bearing at roll body two ends, and described driven gear is arranged at roll shaft bearing outside,
