Patent documentation 1 Japanese Patent Application Publication No.2000-318282

Summary of the invention

Whether yet the adjustment of seal face need be implemented before striking seal, and finish for the adjustment that confirms the seal face, and chapter is struck in the adjustment of seal face and examination to be needed to carry out repeatedly, requires considerable time and effort thus.

In addition, if a plurality of seal face is formed by different materials, then exist other problem.That is, each seal mask has its oneself applied pressure best, therefore, if use the suitable pressure of seal face is struck seal, and then other seal face may cause smudgyly, or printing ink may ooze out inversely.

The present invention has reached and has solved the above problems, and an object of the present invention is to provide the seal that can guarantee the seal quality, and it realizes purpose by the pressure that each face to a plurality of seal faces applies a best.

In order to achieve the above object, seal of the present invention comprises: one first seal body, and it is fixed on the body shell and has first a seal face that is used for forming a seal image; One second seal body, it has an exposed hole, and the first seal face exposes by this hole, and one second seal face, and it is used for forming seal image with the first seal face that exposes by exposed hole; And a limiting member, it maintains second seal body and limits a distance, wherein, when body shell presses down when striking chapter, the second seal face pressurized.

Seal of the present invention also can comprise a retaining member, and its opposite side from the second seal face keeps second seal body; One framing component, it pinches folder second seal body with retaining member, so that the second seal face exposes; An and damper member, it contacts with framing component with body shell, wherein, limiting member is made of framing component and damper member, when striking chapter, damper member pressurized causes framing component to press down, and the second seal face that exposes of compression, up to framing component with till the destination media that strikes chapter contacts.

Seal of the present invention can so be constructed: when not striking chapter, the first seal face be arranged on along with strike Zhang Fang in the opposite direction from a position that the second seal reduction of area advances, and damper member pressurized, like this, when body shell presses down when striking chapter, the first seal face and the second seal face are become flush each other.

Seal of the present invention can so be constructed, and it comprises an elastic component, and elastic component contacts with first seal body with body shell, wherein, the elastic component pressurized, like this, when body shell pressed down when striking chapter, the first seal face and the second seal face became and flush each other.

In seal of the present invention, when body shell presses down and strikes chapter, the second seal face with strike the chapter destination media and contact, and when it further pressed down, limiting member contacted with striking the chapter destination media, like this, even apply further power, the second seal face also keeps not being subjected to the loading of this power.Therefore, the second seal face does not load any excessive power, thus, does not cause fuzzy or leakage printing ink.First seal body on the other hand, can obtain to strike chapter clearly, because can load with a desirable power.

In addition, in seal of the present invention, second seal body is kept by framing component and retaining member, and like this, when not striking chapter, the second seal face is slightly outstanding from framing component.If body shell presses down when striking chapter, then second seal body keeps contacting with framing component by pushing away under the damper member, and the second seal face with strike the chapter destination media and contact.When pushing away under further, framing component contacts with striking the chapter destination media, and like this, even apply further power, second seal body also keeps not being subjected to the loading of this power.That is, an outstanding distance of second seal body when only equaling not carry out striking chapter by one, second seal body is pressurized.On the other hand, first seal body is subjected to a pressure in doing so, and like this, it is pressurized and realize striking chapter fully.Because there is not excessive power to be applied to second seal body, so, do not take place fuzzy and the printing ink leakage, and because a desirable power can be applied to first seal body, so, can obtain to strike clearly chapter.

Because in seal of the present invention, the first seal face presses down more than the second seal face, so, although, but, can obtain the fabulous chapter that strikes because two seal faces keep flushing each other always the first seal face and the second seal face are not positioned on the equal height.

Because seal of the present invention is provided with the elastic component between the body shell and first seal body, so, when body shell presses down when striking chapter, the elastic component pressurized, up to the second seal face and the first seal face become each other flush till.Therefore, even the user does not adjust height in use, a suitable pressure also can be applied to each of the first seal face and the second seal face, thereby can reach the fabulous chapter that strikes.

As illustrated in fig. 1 and 2, date stamp 1 has the body shell 2 of a substantial cylindrical, and the hole that is positioned at the cylinder-shaped end 2a on body shell 2 one ends is done to such an extent that be slightly larger than its body.Cylinder-shaped end 2a has a seal face that forms a seal image on the seal destination media.The seal face is a circular basically seal face, it has a plane perpendicular to the axial direction of body shell 2, and be constructed to be permeable to form a seal image by a synthetic seal face 111, the seal image of seal face 111 does not change with seal face 211, and seal face 211 can form the seal image such as any data that formed by combined digital and symbol.One cap 10 is provided, and when date seal 1 did not use, cap can be protected

seal face

111 and 211 after living, and this cap 10 can be pulled down from the cylinder-shaped end 2a of body shell 2.

The cylinder-shaped end 2d of one rear end part, 205 (see figure 3)s of removable seal part 200 from the opposite side of the cylinder-shaped end 2a that is arranged in body shell 2 exposes.It keeps body shell 2, and along the circumferential direction roughly turns over 180 when spending with respect to body shell shown in Figure 22 when rear end part 205, and removable seal part 200 is rotated with rear end part 205.Then, the operation part 221 of a sliding-type is exposed from an opening portion 2b, and described opening portion 2b opens wide in the outer peripheral edges face of body shell 2.Described in hereinafter, this operation part 221 is used to change the seal face 211 that provides with polytype.

As shown in Figure 3, keep the removable seal part 200 of seal face 211 and the fixing seal part 100 of maintenance seal face 111 to be contained in the body shell 2.

Fixing seal part 100 comprises that one wherein forms fixing seal member 112 (see figure 5)s of a seal face 111, and one contact with fixing seal member 112 and to be used for the black body 113 of storage supplying printing ink and kept by cylindrical retaining member 125 (see figure 5)s, this cylindrical retaining member 125 is from storing up seal member 112 and the Chu Mo body 113 that black body 113 sides are maintained fixed, an and cylindrical frame member 120, it is fitted into the outer peripheral edges of retaining member 125, expose seal face 111 from fixing seal member 112 sides simultaneously, and the seal member 112 and the Chu Mo body 113 that are maintained fixed with retaining member 125.Then, framing component 120 is fitted into the inner peripheral of the cylinder-shaped end 2a of body shell 2, so that fixing seal part 100 is contained in the body shell 2.Two spiral slots 121 are arranged in the outer peripheral edges of framing component 120, so that be accommodated in the opening of closing cylinder-shaped end 2a under the state in the body shell 2 with fixing seal part 100 in removable seal part 200.Two boss 2c that are provided with relative to one another highlightedly from the inner peripheral of the cylinder-shaped end 2a of body shell 2 engage with spiral slot 121.

By promoting the bottom surface of spiral slot 121, a stopper 121b is arranged on the terminal 121a place of spiral slot 121, when the seal part 100 of fixing advance/when withdrawing, the boss 2c that is positioned at terminal 121a place is restricted along moving of spiral slot 121 directions.One stopper 121c also is arranged on the starting end place of spiral slot 121, and when fixing seal part 100 relaxed, the motion of boss 2c was subjected to the restriction of stopper 121c, thus, prevents that the seal part 100 of fixing from skidding off outside the body shell 2.

According to this embodiment, fixing seal part 100 is configured to roughly 180 degree with respect to the angle of rotation of body shell 2, the seal part 100 of rotational fixation by mobile boss 2c, it at first is positioned at the terminal 121a place of spiral slot 121, rotate above stopper 121b along spirality 121, till its motion is blocked piece 121c obstruction.This corner preferably is at least about 90 degree or 270 degree.This reason is, if the corner of fixing seal part 100 is less than 90 degree, then when rotating, fixing seal part 100 cause the resistance that is applied to boss 2c with spiral slot 121 sliding-contacts to increase, because the moving direction of the seal part 100 that the direction of the guide ledges 2c of spiral slot 121 approaches to fix.Another reason is, if corner greater than 270 degree, then needs to discharge body shell 2 or the fixing seal part 100 that the user grasps, and when the user uses the seal part 100 of body shell 2 rotational fixation that grasp, need grasp once more.

A pair of ways 123 is outstanding from the inside of the framing component 120 of fixing seal part 100 along the relative direction of seal face 111.Guide pad 232 near the short side of two maintenance bodies 230 that are arranged on hereinafter the removable seal part of describing 200 highlightedly the side, quilt is pinched is clipped in this between the ways 123.Therefore, the motion of the seal part 100 that restriction is fixing is so that it only can in axial direction slide.That is, when boss 2c when spiral slot 121 slides, fixing seal part 100 is in axial direction advanced with respect to body shell 2 or is withdrawn.

Pair of protruding portions 122 is arranged on the side of framing component 120 of the seal member 112 that is maintained fixed and Chu Mo body 113.Ledge 122 engages each the bonding part (not shown) that is arranged on cap 10 inner faces.The exposed hole 114 of one essentially rectangular along perpendicular to the direction of the face of seal face 111 by fixing seal part 100, this exposed hole be formed on basically fixing seal part 100 seal face 111 in intracardiac.Exposed hole 114 is to expose the movably hole of the seal face 211 of seal member 210 in body shell 2.Above-mentioned ledge 122 is arranged on the side of the framing component 120 on the both sides of short side direction of exposed hole 114.Fixing seal part 100 is corresponding to second seal body of the present invention, and seal face 111 is corresponding to one second seal face.

Next, movably seal part 200 supporting movably seal member 210 remain on maintenance body 230 in the cylindrical bearing shell 201.As shown in Figure 4, movably seal member 210 is fixed on the outer peripheral edges face of each belt body of five belt bodies 220, five belt bodies 220 are supported abreast respectively, and rotatable along the length direction of the maintenance body 230 of essentially rectangular, so that it moves along with the rotation of belt body 220.Movably seal member 210 is arranged on the outer peripheral edges face of belt body 220 highlightedly, and a plurality of seal parts 212 that have seal face 211 at its front end place are provided with abreast along the rotation direction of belt body 220, and the root of corresponding seal part 212 connects by a blank area 213.This movably the length of seal member 210 less than half of the length of belt body 220.Seal part 212 with seal face 211 and blank area 213 has constituted this movably seal member 210, and seal part 212 is soaked into body by the China ink such as porous resin and formed and form one.Simultaneously, movably seal member 210 is corresponding to first seal body of the present invention, and seal face 211 is corresponding to one first seal face.

The operation part 221 of operating respectively and rotating each belt body 220 is arranged on the outer peripheral edges face of belt body 220 highlightedly, and by along the length direction slide part 221 that keeps body 230, belt body 220 can rotate.Be stamped in corresponding to a seal image sample 222 of the seal face 211 of each seal part 212 on the outer peripheral edges face on the opposite side of a wherein fixing movably side of seal member 210 of belt body 220.When any seal part 212 is positioned on the side owing to operated operation part 221 along the length direction that keeps body 230, be positioned on the another side corresponding to the sample 222 of the seal image of this seal face 211.One sample window 2e (see figure 5) is formed in the bottom surface of the rear end part 205 of seal part 200 movably, like this, can see along the length direction that keeps body 230 by sample window 2e to be positioned at sample 222 on the another side.

As shown in Figure 5, a ledge 223 is arranged on the operation part 221 of belt body 220 highlightedly, and pushing ledge 223 can advance/withdraw in the edge it perpendicular to a direction of the glide direction of operation part 221.Be used for location when engaging ledge 223 and the rotation of belt body 220 is applied the sunk part 231 of a load, along be set to the quantity identical in the rotation direction that keeps the belt body 220 on body 230 inner faces with seal part 212.The purpose of this structure is to locate belt body 220, so that be positioned at when ledge 223 engages with sunk part 231 along on the side of the length direction that keeps body 230 corresponding to the seal part 212 of sunk part 231.The seal part 212 of the correspondence of Ding Wei five belt bodies 220 is arranged abreast in this way, and be contained in the body shell 2 and be inserted in the exposed window 114 during with 100 sealings of fixing seal part in seal part 200 movably, so that its parallel arranged direction is consistent with the length direction of exposed hole 114.At this moment, the ways 123 of fixing seal part 100 is pinched the guide pad 232 that presss from both sides on the maintenance body 230 that is positioned at removable seal part 200, and fixing seal part 100 is with respect to removable seal part 200 location.Therefore, the direction that is arranged in parallel of seal part 212 accords with the length direction of exposed hole 114.

As mentioned above, supporting shell 201 forms cylindrical, with the consistent (see figure 3) of inner peripheral of the body shell of holding 2.Shown in Fig. 3,5, one bead 203 is arranged on the place, an end on seal face one side of supporting shell 201, and along outstanding perpendicular to the direction of outer peripheral edges face, like this, form one with the parallel plane surface of direction perpendicular to the axial direction of the body shell 2 of holding supporting shell 201.The outer peripheral edges of bead 203 are substantially equal to the inner peripheral of the cylinder-shaped end 2a of body shell 2, and the inner peripheral of the cylinder-shaped end 2a of body shell 2 has the bore dia bigger than body diameter.Two notch portion 204 are arranged in the bead 203, avoid disturbing with boss 2c with in supporting shell 201 is received into body shell 2 time.The damper member 300 of one ring-type has the shape roughly the same with the plane of bead 203, and this damper member is arranged between fixing the seal part 100 and bead 203.

As shown in Figure 3, four elongated gathering sills 202 in axial direction open wide in the side of supporting shell 201.When keeping body 230 to be contained in the supporting shell 201, the operation part 221 of two belt bodies 220 of respective operations part 221 1 ends of close five belt bodies 220, be projected into the outside of supporting shell 220 by same gathering sill 202, and the operation part 221 of its excess-three belt body 220 is from independently gathering sill 202 is outstanding.In addition, when the seal face can be changed as illustrated in fig. 2, all four gathering sills 202 exposed by opening portion 2b.

Next, the detailed structure of fixing seal part 100 will be described, and printing ink is fed to fixing seal part 100 and removable seal part 200.As shown in Figure 5, in fixing seal part 100, cylindrical retaining member 125 is from storing up seal member 112 and the Chu Mo body 113 that black body 113 sides are maintained fixed, and the seal face 111 of the seal member 112 that is maintained fixed, like this, seal face 111 is exposed in the framing component 120 with L shaped cross section roughly by driving, makes it be fitted into the outer peripheral edges of retaining member 125.By framing component 120 is driven in the retaining member 125, part near the fixing seal member 112 of outer peripheral edges is pinched in the state that is clipped in a compression by framing component 120 and retaining member 125, and produces a height difference H between end face of framing component 120 and the seal face 111 in an expose portion of fixing seal member 112.

Store up black body 113 and for example be made up of porous resin, it can soak into printing ink and with ink containment by inside.Fixing seal member 112 also is made up of porous resin, forms seal face 111 by exposing porous resin, and a part changes into a seal image of the fixing seal member of covering 112 according to traditional method, and like this, exposed portions is melted and the obstruction aperture.From storing up black body 113 China ink is supplied to fixing seal member 112.

Printing ink supporting body 130 is arranged on the one side on the opposite side of the face that contact with the fixing seal member 112 that stores up black body 113 so that it contact with the seal part 212 of seal member 210 movably, its maintenance of while with store up black body 113 and contact.Printing ink supporting body 130 for example is made up of felting and is carried printing ink, utilizes capillarity to be penetrated into the storage China ink body 113 of fixing seal part 100, is penetrated into the seal part 212 of the removable seal member 210 that contacts with printing ink supporting body 130, so that supply printing ink.Be diffused into fully entirely by printing ink from the printing ink that stores up 113 carryings of black body by printing ink supporting body 130 and soak in the movably seal member 210 that body forms, like this, printing ink is sent to corresponding seal part 212.

Apply pressure to the pressure adjustmenting mechanism of fixing seal part 100 and removable seal part 200 when next, seal is struck in description.As mentioned above, form place, the end (see figure 3) that identical with the plane of bead 203 basically annular damper member 300 is arranged on supporting shell 201.This stops damper member 300 to disturb and keeps body 230, and this keeps the movably seal member 210 of body maintenance by supporting shell 201 supportings.Damper member 300 has two notch portion 301, and they are corresponding to two notch portion 204 in the bead 203.If the notch portion 301 when body shell 2 assemblings in the damper member 300 is mated with the notch portion 204 in the bead 203, can not cause interference in the time of then in supporting shell 201 is installed in body shell 2.

As shown in Figure 5, the face of the damper member 300 on the opposite side of bead 203 contacts with the rear end 124 of framing component 120.That is, because the retaining member 125 of fixing seal part 100 is formed on a lower position, with framing component 120 spaced apart gaps 126, so damper member 300 does not contact with retaining member 125, but it contacts with framing component 120.Therefore; when the user who catches body shell 2 applies power along the direction of striking seal; retaining member 125 directly is not pressed; but damper member 300 pressurizeds; and framing component 120 is pressed against one and strikes (see figure 6) on the chapter destination media 50; therefore, protect fixing seal member 112 to be no more than the printing ink leakage of pushing with needing and causing inside to keep.

In the time of in supporting shell 210 is contained in body shell 2, it along the circumferential direction is supported rotationally.At this moment, the cylinder-shaped end 2d of the edge contact body shell 2 of the rear end part 205 that exposes from the cylinder-shaped end 2d of body shell 2, thus, restriction supporting shell 201 moves to the cylinder-shaped end 2a of body shell 2 along a direction.In addition, supporting shell 201 is limited to move to along a direction cylinder-shaped end 2d of body shell 2 by bead 203 because the body part of body shell 2 on diameter less than cylindrical end portion 2a.

When the date stamp 1 with structure like this is assembled, as shown in Figure 3, at first, separable rear end part 205 separates from supporting shell 201, this supporting shell 201 is inserted in the body shell 2 from the cylinder-shaped end 2a of body shell 2, then, the side from cylinder-shaped end 2d engages and is fixed on the there with rear end part 205 and supporting shell 201.Then, be positioned on the body shell 2 is that boss 2c engages with the spiral slot 121 of the seal part 100 of fixing, simultaneously, firmly make two guide pads 232 of maintenance body 230 between a pair of ways 123 of fixing seal part 100, from cylinder-shaped end 2a side so that the seal part 100 that installs and fixes.All four gathering sills 202 expose by opening portion 2b as shown in Figure 2, wherein, the boss 2c that engages with spiral slot 121 skips stopper 121c from the starting end of spiral slot 121, at this moment, movably the selected seal face 211 of seal member 210 keeps being drawn out exposed hole 114 in the fixing seal part 100.If operation part 221 is operated, then can select seal face 211 arbitrarily under this state.

Next, boss 2c slides along spiral slot 121 by the seal part 100 of rotational fixation.If fixing seal part is rotated for 100 this moments, then supporting shell 201 also rotates, because guide pad 232 pinches is clipped between the ways 123.Therefore, this program can be carried out by the rear end part 205 with respect to body shell 2 rotating support shells 201.If boss 2c is by spiral slot 121 guiding (as shown in Figure 1), then fixing seal part 100 moves along the direction that is received in the body shell 2, and when boss 2c skips the stopper 121b of spiral slot 121 and arrives an end position, as shown in Figure 5, Gu Ding seal part 100 navigates to body shell 2.

In order to change seal face 211, rear end part 205 rotates, and identical mode maintains body shell 2 with date stamp 1 assembling the time, and like this, boss 2c slides along spiral slot 121.Then, Gu Ding seal part 100 is advanced or is withdrawn along the axial direction of body shell 2 as described above.When fixing seal part 100 moves in the state that allows to strike chapter, fixing seal part 100 and removable seal part 200 are not approaching apace each other, thus, reduce to be applied to the load of the damper member 300 that is clipped in the middle, because the direction (axial direction of body shell 2) that the direction of spiral slot 121 guide ledges 2c is advanced/withdrawn with respect to fixing seal part 100 is inclination.

Incidentally, there is not the wall that is positioned on the seal face side at the terminal 121a place of spiral slot 121.The scope that fixing seal part 100 can move along the axial direction of cylinder-shaped body shell 2 when boss 2c is positioned at terminal 121a place, two positions of can going directly, a position, boss 2c is along the wall of the direction contact spiral slot 121 of the cylinder-shaped end 2a of body shell 2, in the another location, the rear end 124 of framing component 120 is along the direction contact bead 203 of the cylinder-shaped end 2d of body shell 2.Damper member 300 is constructed like this: its thickness member not during pressurized greater than fixing seal part 100 scope movably.Therefore, when date seal 1 is in the state that allows to affix one's seal, damper member 300 always contact with the rear end 124 of the framing component 120 of fixing seal part 100 and the bead 203 of removable seal part 200, simultaneously, along the direction that their are separated oppress them both.Therefore, when not affixing one's seal, the seal face 111 of the movably seal member 200 that can move along the axial direction of body shell 2, than the seal face 211 of the removable seal member 210 of supporting shell 201 supportings that are limited to move along the axial direction of body shell 2, more outstanding along the direction of affixing one's seal.In addition, fixing seal part 100 is subjected to the compressing of damper member 300, so that the boss 2c of body shell 2 keeps contacting with the wall of spiral slot 121, thus, prevents that the seal part 100 of fixing is lax.

This damper member 300 is formed by the elastomeric flexible member such as polyurethane foam, felting.As mentioned above, fixing seal member 112 and movably seal member 210 form by porous resin, and damper member 300 is formed by elastomeric material, along with the increase of elastomeric material decrement, its counter-force also increases.The thickness of damper member 300 need be set like this: the maximum compression time of damper member 300 and the thickness difference between the non-compression time (absorption size) are greater than the mobile range of fixing seal part 100.

When date seal 1 was used for affixing one's seal as illustrated in fig. 6, the seal face was pressed against on the destination media 50 of affixing one's seal and catches body shell 2.At this moment, the seal face 111 of the fixing seal member 112 more outstanding more than the seal face 211 of seal member 210 movably contact with the destination media 50 of affixing one's seal in advance, like this, when affixing one's seal, fixing seal member 112 acceptance one counter-force.By above-mentioned difference of hardness is provided, the damper member 300 more soft more than fixing seal member 112 absorbs and more manys counter-force, therefore than the seal member of fixing 112 pressurized more.If 300 compressions of damper member are so that its thickness reduces, then Gu Ding seal part 100 moves to the cylinder-shaped end 2d of body shell 2 along a direction.Then, limit the seal part 212 of the movably seal member 210 of the removable seal part 200 that moves with respect to body shell 2, relatively along moving from exposed hole 114 outstanding directions.Then, the seal face 111 of Gu Ding seal member 112 and movably the seal face 211 of seal member 210 on the surface of destination media 50 of affixing one's seal, become and flush each other.

When another pressure was applied on the destination media 50 of affixing one's seal, damper member 300 further compressed, so that seal part 212 is along further moving from exposed hole 114 outstanding directions.Because the seal member 112 that the framing component 120 of the seal member 112 that is maintained fixed is maintained fixed, so that it is from seal face 111 outstanding amount H (as shown in Figure 5) of fixing seal member 112, so, the seal member 112 further pressurizeds that restriction is fixing, but framing component 120 arrives the destination media 50 of affixing one's seal, and compression height H just.Therefore, be applied to by the desirable stress level of user on the seal part 212 of seal member 210 movably, and the pressure that is applied to fixing seal member 112 is subjected to the restriction of framing component 120.Therefore, can form one and not have seal image fuzzy or that printing ink leaks.

In the date stamp 1 of this embodiment as mentioned above, damper member 300 is arranged between fixing seal part 100 and the removable seal part 200, and the seal face 111 of fixing seal part 100 is outstanding along the direction of affixing one's seal with respect to the seal face 211 of removable seal part 200.When affixing one's seal, before seal face 211, seal face 111 contacts with the destination media of affixing one's seal, and than the counter-force of the soft more damper member 300 of fixing seal member 112 by the destination media of affixing one's seal than fixing seal member 112 pressurized more.Therefore, seal face 111 and seal face 211 become on the surface of destination media 50 of affixing one's seal and flush each other, so, inhomogeneities does not take place in the seal image that produces by synthesized seal face 111 and seal face 211.

Even strengthen plus-pressures when obtaining a more clear seal image by seal face 211 as the user, the compression of fixing seal member 112 also is restricted with the destination media position contacting place that affixes one's seal at framing component 120, because in the position from the outstanding compression distance H of seal face 111, damper member 300 only keeps in touch with the framing component 120 of the seal member 112 that is maintained fixed.Therefore, the printing ink that remains in the fixing seal member 112 does not leak out by excessive plus-pressure, or leaks out outside the exposed hole 114.Therefore, the protection destination media of affixing one's seal is avoided polluting, and can obtain a seal image clearly.

Do not use superfluous words, the present invention can make amendment in every way.Although movably seal member 210 is formed by porous resin, it is not limited to this example, can be formed by the rubber of porous, metal, pottery etc.Although made up two seal faces according to this embodiment, if but make up three or more seal faces, then allow to fix one of them and adjust other that have the damper member several, like this, when affixing one's seal, all seal faces become on identical plane and flush.

Movably seal member 210 can dismantle and with seal face 111 combinations of fixing seal part 100 so that form a single seal face.In addition, being used for exposing movably that the exposed hole 114 of the seal part 212 of seal member 210 is not limited to is a hole, but can be to cut one, if the side of fixing seal member 112 and Chu Mo body 113 is relative with seal part 212, then admissible any structure.

Although the shape set of damper member 300 is roughly the same with the shape of the bead 203 of supporting shell 201, if but the volume of damper member 300 does not increase when compression, or be provided with enough distances not contact with the inner face of body shell 2 during to expansion in compression vertically with along right and left for damper member 300, then damper member 300 can be different shapes with bead 203.

Next, with reference to Fig. 7-9 second embodiment of the present invention is described.Fig. 7 is the stereogram that the date stamp 1 of second embodiment disassembles.Fig. 8 is the sectional view of the date stamp 1 of second embodiment, and it is watched from the direction of arrow B with respect to the chain-dotted line among Fig. 1.Fig. 9 is the sectional view of the date stamp 1 of second embodiment when striking chapter.In a second embodiment, the present invention is applicable to the date stamp 1 identical with first embodiment.Therefore, first embodiment is used for following description about Fig. 1,2,4 description and corresponding accompanying drawing, and identical label is attached on the parts identical with first embodiment in Fig. 7-9, omits the description to it simultaneously.

As shown in Figure 7, although the date stamp 1 with first embodiment is identical basically for the date stamp 1 of second embodiment, between fixing seal part 100 and bead 203, damper member 300 is not set.Therefore, different with first embodiment, fixing seal part 100 is limited in axial direction to move with respect to body shell 2, because it is not subjected to the compressing of damper member 300.As shown in Figure 8, keep movably that the supporting shell 201 of seal member 210 has a rib 410, it is projected on the inboard near the end on the seal face side and keeps body 230.Be arranged on along between two guide pads 232 and rib 410 of the short side direction extension that keeps body 230 as the spring 400 of an elastic component.One end of spring 400 is fixed to body shell 2 by supporting shell 201 by rib 410, and its other end is fixed to first seal body 200 by guide pad 232.Its result, the seal face 211 of removable seal part 200 is pushed to body shell 2 sides by spring 400, and like this, when not affixing one's seal, it is positioned at a position that retreats into the inside of body shell from the seal face 112 of fixing seal part 100 slightly.According to second embodiment, when not affixing one's seal, be applied to the fixing seal part 100 and the thrust of seal part 200 movably with spring 400 adjustment.

Promptly, if when affixing one's seal with date stamp 1, the user grasps body shell 2 and applies a power along the direction of affixing one's seal, the seal face is pressed against on the destination media of affixing one's seal, then the rib 410 in the supporting shell 201 compresses guide pad 232 by spring 400, therefore, movably the seal part 212 of seal member 210 moves along the directions of giving prominence to from exposed hole 114 shown in Figure 9.On the other hand, the seal face 111 of fixing seal member 112 at first contact with the destination media of affixing one's seal, because it is given prominence to respect to the seal part 212 of seal member 210 movably.Yet, fixing seal member 112 is compressed height H, because framing component 120 keeps this fixing seal member 112,, and after arriving the destination media of affixing one's seal, framing component 120 further limits its pressurized so that it is from the seal face 111 projecting height H of fixing seal member 112.Then, because movably seal member 210 is outstanding from exposed hole 114, spring 400 is compressed as illustrated in fig. 9, so, the seal face 111 of fixing seal member 112 and movably the seal face of seal member 210 on the destination media of affixing one's seal, become and flush each other.

In the date stamp 1 of second embodiment, as mentioned above, do not have damper member 300 to be arranged between fixing seal part 100 and the removable seal part 200, and spring 400 is arranged between supporting shell 201 and the removable seal part 200.Its result, removable seal part 200 moves with respect to body shell 2, and fixing seal part 100 is fixing.Because when affixing one's seal, one compression distance of the seal member 112 that framing component 120 restrictions are fixing, but before seal face 211, seal face 111 contacts with the destination media of affixing one's seal, on the other hand, removable seal part 200 makes springs 400 compressions from exposed hole 114 is outstanding, the seal face 111 of fixing seal member 112 and movably the seal face 211 of seal member 210 on the surface of destination media of affixing one's seal, become and flush each other.In addition, absorb user's excessive amount of pressure because of spring 400 compressions, so, the leakage of impossible generation printing ink or smudgy on seal face 111 and seal face 211.Therefore, even the user does not implement Height Adjustment or examination is affixed one's seal, in the seal image that can form by synthesized seal face 111 and seal face 211 inhomogeneities not taking place, thus, guarantees a distinct image yet.

Although according to second embodiment, spring 400 is used as elastic component of the present invention, and this is not limited to spring, also can be rubber, polyurethane foam etc., as long as it is flexiblely just can.In addition, the installation site of spring 400 is not limited between rib 410 and guide pad 232, and it also can be arranged to the axial direction shrink/expanded along body shell 2, makes the one end and the other end keep respectively contacting with seal member 210 movably with supporting shell 201.

Next, with reference to Figure 10,11 third embodiment of the present invention is described.Figure 10 is the sectional view of the date stamp 1 of the 3rd embodiment, and it is watched from the direction of arrow B with respect to the chain-dotted line among Fig. 1.Figure 11 is the sectional view of the date stamp 1 of the 3rd embodiment when striking chapter.In the 3rd embodiment, the present invention is applicable to the date stamp that is similar to first and second embodiment.Therefore, in the following description, use first embodiment about Fig. 1,2,3,4 description and corresponding accompanying drawing, and identical label is attached on the parts identical with first and second embodiment in Figure 10,11, omits the description to it simultaneously.

As shown in figure 10, the date stamp 1 with first and second embodiment is identical basically for the date stamp 1 of the 3rd embodiment.Promptly, the date stamp of the 3rd embodiment has the damper member 300 identical with first embodiment, and be similar to second embodiment and have a rib 410, it is projected in the maintenance body 230 near the end on the seal face side that keeps the supporting shell 201 of seal member 210 movably.Be arranged between two guide pads 232 and rib 410 that extends from the side along the short side direction that keeps body 230 as the spring 400 of an elastic component.Therefore, when the date seal can be pressed, damper member 300 remained with the rear end 124 of the framing component 120 of fixing seal part 100 and the bead 203 of removable seal part 200 and contact, simultaneously, oppresses them along their directions separated from one another.One end of spring 400 is fixed to body shell 2 by supporting shell 201 by rib 410, and its other end is fixed to first seal body 200 by guide pad 232.Its result, the seal face 211 of removable seal part 200 is pushed to body shell 2 all the time by spring 400.According to the 3rd embodiment, when affixing one's seal, can implement adjustment to the thrust of fixing seal part 100 and removable seal part 200 by damper member 300 and spring 400.

If the user who catches body shell 2 when pushing date stamp 1 is along the direction application of force of affixing one's seal, make its seal face be pressed against (as shown in figure 11) on the destination media of affixing one's seal, the seal face 111 of then outstanding with respect to the seal face 211 of seal member 210 movably fixing seal member 112 at first contacts with the destination media 50 of affixing one's seal, and when affixing one's seal, fixing seal member 112 is accepted a counter-force from the destination media 50 of affixing one's seal.Yet, the damper member 300 more flexible more than fixing seal member 112 absorbs this counter-force, because as described in first embodiment, between fixing seal member 112 and the damper member 300 difference of hardness is arranged, so the seal member 112 that damper member 300 ratios are fixed is pressurized more.When damper member 300 compressed to such an extent that its thickness is reduced, fixing seal part 100 moved to the cylinder-shaped end 2d of body shell 2 along a direction.When body shell 2 was pressed against on the destination media of affixing one's seal, the rib 410 in the supporting shell 201 pushed away guide pad 232 by spring 400, so that movably the seal part 212 of seal member 210 moves along the directions of giving prominence to from exposed hole 114.Because fixing seal member 112 and movably seal member 210 is removable with respect to body shell 2, so by fixing seal member 112 and movably seal member 210 both can carry out adjustment highly, therefore, the seal face 111 of Gu Ding seal member 112 and movably the seal face 211 of seal member 210 on the destination media surface of affixing one's seal, become and flush each other.

When another pressure was applied on the destination media 50 of affixing one's seal, damper member 300 further compressed, so that seal part 212 moves along a direction of stretching out outside the exposed hole 114.Yet, when framing component 120 arrives on the destination media 50 of affixing one's seal, fixing seal member 112 is compression height H only, because the seal member 112 that the framing component 120 of the seal member 112 that is maintained fixed is maintained fixed, make it from the seal face 111 of fixing seal member 112 projecting height H only, yet, but further compression of restriction.Therefore, the pressure of the desired level of user is applied to the movably seal part 212 of seal member 210, and the pressure that is applied to fixing seal member 112 is subjected to the restriction of framing component 120, and like this, can form does not have seal image smudgy or that printing ink leaks.
