Description

本発明は、被捺印面に対する印面の接触量を的確容易に規制して印字濃度を簡単に微調整でき、しかも、調整部材の緩みや損傷によって印面の接触量規制が解除されることを防止できるようにした多孔性印材を用いた印判に関するものである。 The present invention makes it possible to easily and finely adjust the printing density by accurately and easily regulating the contact amount of the printing surface with respect to the surface to be printed, and to prevent the restriction of the contact amount of the printing surface due to looseness or damage of the adjustment member. The present invention relates to a stamp using such a porous stamping material.

多孔性印材を用いた印判は連続捺印が可能なため広く普及しているが、捺印圧の強弱によってインキが紙面に過剰に付着して印影が潰れたり、インキの付着量が不足して印影がかすれたりして印字不良を生じるという問題があるため、捺印圧を一定にするための捺印圧調整機構を組み込んだ印判が提案されている。（例えば、特許文献１、２、３、４参照）。 Stamps using porous stamping materials are widely used because they can be continuously stamped, but the ink sticks excessively on the paper surface due to the strength of the stamping pressure, and the imprint is crushed or the ink deposit is insufficient. Since there is a problem that printing defects occur due to fading, a stamp incorporating a printing pressure adjusting mechanism for making the printing pressure constant has been proposed. (For example, see Patent Documents 1, 2, 3, and 4).

しかしながら、従来のものはいずれも調整機構をロックする機構がないため、長期間使用しているうちに捺印圧調整機構が調整部材の緩みや損傷によって有効に作用されなくなって調整量が変わってしまい、適正な捺印ができなくなるという問題がある。しかも、スライド量の微調整が難しいので光沢紙のように僅かなスライド量で適正な捺印領域からずれるものには対応できないという問題もあった。 However, none of the conventional ones has a mechanism for locking the adjusting mechanism, so that the printing pressure adjusting mechanism is not effectively operated due to looseness or damage of the adjusting member during long-term use, and the adjustment amount changes. There is a problem that proper stamping cannot be performed. In addition, since it is difficult to finely adjust the slide amount, there has been a problem that it is not possible to deal with a thing that deviates from an appropriate marking area with a small slide amount like glossy paper.

本発明は前記のような問題を解決して、被捺印面に対する印面の接触量を的確容易に規制して印字濃度を簡単に微調整でき、しかも、調整部材の緩みや損傷を防止できるようにした印判を提供することを目的とするものである。 The present invention solves the above-mentioned problems, and can easily finely adjust the printing density by accurately and easily regulating the contact amount of the printing surface with respect to the surface to be printed, and can prevent loosening and damage of the adjusting member. The purpose is to provide an official seal.

前記のような課題を解決した本発明の印判は、下端の印材収納部に多孔性印材を収納した印材ホルダを外套枠の内側に昇降動自在に装着するとともにこの印材ホルダの上部に把持部材を嵌着してある印字体ユニットを前記した多孔性印材の印字面が弾発ばねによって常時は外套枠の脚端よりやや上方に位置されるように装着するとともに、前記した外套枠３に対する印字体ユニットの印字面を捺印条件に応じた位置に微調整する捺印圧調整機構を組み込んだ印判であって、前記した捺印圧調整機構が、印材ホルダの中央頂部に立設したねじ棒と、このねじ棒に螺合されてその正逆回動により外套枠に対する印字体ユニットの高低位置を調整する調整ノブとを少なくとも備えたものであり、さらに、この調整ノブの回動を阻止する緩み止め機構を印判内部に設けられており、且つ、前記した緩み止め機構が、調整ノブの外周面に形成してあるローレットと、把持部材の内面に形成されて前記したローレットと係合する係止片とよりなるものてあることを特徴とする。 The stamp of the present invention that has solved the above-mentioned problems is that a stamping material holder containing a porous stamping material is mounted in the stamping material storage part at the lower end so as to be movable up and down inside the mantle frame, and a gripping member is provided above the stamping material holder. The attached printing body unit is mounted so that the printing surface of the porous printing material is always positioned slightly above the leg end of the outer frame by a spring, and the printing body with respect to the outer frame 3 is mounted. A stamp that incorporates a printing pressure adjustment mechanism that finely adjusts the printing surface of the unit to a position according to the printing conditions. The above-mentioned printing pressure adjustment mechanism includes a screw rod that stands upright at the center top of the printing material holder, and the screw. A locking mechanism that at least includes an adjustment knob that is screwed to the bar and adjusts the height of the printing unit relative to the outer frame by forward and reverse rotation, and further prevents the adjustment knob from rotating. Stamp provided inside, and, more above-mentioned locking mechanism, the knurls are formed on the outer peripheral surface of the adjustment knob, the locking piece is formed on the inner surface of the gripping member engages knurled and that the characterized in that that is Te becomes one.

なお、調整ノブの回動を阻止する緩み止め機構は、調整ノブの外周面に形成してあるローレットと、把持部材の内面に形成されて前記したローレットと係合する係止片とよりなるものであればよいが、弾発ばねにより常時は上向きに弾発されるスライド部材をその脚部が外套枠の上部内面に添って上下摺動可能に組み込んでおき、このスライド部材の天板部上面に複数の円弧状凹部を配設しておく一方、前記した調整ノブの下面に前記した円弧状凹部と係合する係合用凸部とを設けておき、調整ノブの回動により前記した係合用凸部が複数の円弧状凹部のいずれかに係合してこれにより調整ノブの回動操作が節度を付与しながら一定角度宛間欠的に行なわれて外套枠に対する印字体ユニットの高低位置が所定量宛段階的に調整されるようにしておけば、外套枠に対する印字体ユニットの印字面を捺印条件に応じた位置に的確に微調整できるので特に好ましい。 Incidentally, locking Organization for preventing rotation of the adjustment knob, the more the knurls are formed on the outer peripheral surface of the adjustment knob, the locking piece to knurling engage described above is formed on the inner surface of the gripping member Monodea Re may be, but normally leave incorporated to be vertically slidable along the slide member upwardly bullets emitted to the upper inner surface of the leg jacket frame by the elastic spring, the top plate of the slide member A plurality of arc-shaped concave portions are provided on the upper surface of the part, while an engaging convex portion that engages with the arc-shaped concave portion is provided on the lower surface of the adjustment knob. The engaging convex portion engages with any of the plurality of arc-shaped concave portions, so that the rotating operation of the adjustment knob is intermittently performed at a certain angle while giving moderation, and the height of the printing body unit relative to the outer frame Is adjusted step by step to a certain amount If you put, especially preferred because it accurately finely adjusted in position in accordance with the printed surface of the printing drum unit against the mantle frame to seal condition.

本発明の印判は、下端の印材収納部に多孔性印材を収納した印材ホルダを外套枠の内側に昇降動自在に装着するとともにこの印材ホルダの上部に把持部材を嵌着してある印字体ユニットを前記した多孔性印材の印字面が弾発ばねによって常時は外套枠の脚端よりやや上方に位置されるように装着するとともに、前記した外套枠に対する印字体ユニットの捺印圧調整機構を組み込んだものであるから、常時は外套枠の内側に昇降動自在に装着した印字体ユニットの印字面が弾発ばねによって外套枠の脚端よりやや上方に位置されていて印字面により他物を汚すおそれがなく、捺印時には弾発ばねの弾発力に抗して印字体ユニットを押し下げるだげで捺印できることは従来のこの種の印判と同様であるが、本発明では、前記した捺印圧調整機構が、印材ホルダの中央頂部に立設したねじ棒と、このねじ棒に螺合されてその正逆回動により外套枠に対する印字体ユニットの高低位置を調整する調整ノブとを少なくとも備えたものであって、さらに、この調整ノブの回動を阻止する緩み止め機構が内部に設けられているものであるから、印字面を捺印条件に応じた位置に微調整する操作が簡単なうえに、微調整後には調整ノブの回動が皆無となって、長期間使用しているうちに調整ノブの緩みや損傷によって調整量が変わってしまい、適正な捺印ができなくなることがない。また、調整ノブの回動を阻止する緩み止め機構を、調整ノブの外周面に形成してあるローレットと、把持部材の内面に形成されて前記したローレットと係合する係止片とよりなるものとしたことにより調整ノブは把持部材を外さない限りずれることがないので、適正な捺印位置を長期間維持することができるものとなる。 The stamp of the present invention is a printing body unit in which a printing material holder storing a porous printing material in a printing material storage section at the lower end is mounted on the inner side of the outer frame so as to be movable up and down, and a gripping member is fitted on the upper part of the printing material holder Is mounted so that the printing surface of the porous printing material is always positioned slightly above the leg end of the outer frame by means of a spring, and the printing pressure adjustment mechanism of the printing body unit with respect to the outer frame is incorporated. Therefore, the printing surface of the printing unit, which is normally mounted on the inner side of the outer frame so as to be movable up and down, is positioned slightly above the leg end of the outer frame by the elastic spring, and the printing surface may contaminate other objects. As in the case of this type of conventional stamp, the printing pressure adjustment mechanism described above can be used for printing by pressing down the printing unit against the resilience of the spring. A screw rod erected at the center top of the printing material holder, and an adjustment knob that is screwed to the screw rod and adjusts the height position of the printing unit relative to the outer frame by forward and reverse rotation thereof. In addition, since a locking mechanism that prevents the adjustment knob from rotating is provided inside, it is easy to finely adjust the printing surface to a position according to the printing conditions. Since the adjustment knob does not rotate at all, the adjustment amount changes due to looseness or damage of the adjustment knob during long-term use, and proper marking cannot be performed. In addition, a locking mechanism for preventing the adjustment knob from rotating includes a knurling formed on the outer peripheral surface of the adjusting knob, and a locking piece formed on the inner surface of the gripping member and engaged with the knurling described above. As a result, the adjustment knob will not be displaced unless the gripping member is removed, so that the proper marking position can be maintained for a long time.

特に、調整ノブの回動を阻止する緩み止め機構として弾発ばねにより常時は上向きに弾発されるスライド部材をその脚部が外套枠の上部内面に添って上下摺動可能に組み込んでおき、このスライド部材の天板部上面に複数の円弧状凹部を配設しておく一方、前記した調整ノブの下面に前記した円弧状凹部と係合する係合用凸部とを設けておき、調整ノブの回動により前記した係合用凸部が複数の円弧状凹部のいずれかに係合してこれにより調整ノブの回動操作が節度を付与しながら一定角度宛間欠的に行なわれて外套枠に対する印字体ユニットの高低位置が所定量宛段階的に調整されるようにしておけば、印字濃度を調整したいときに被捺印面に対する印面の接触量を規制すべく、把持部材を外したうえねじ棒に螺合されている調整ノブを１ノッチ宛回動させれば、外套枠に対する印字体ユニットの高低位置を調整して印面位置を捺印条件に応じた位置に微調整することができ、この間、調整ノブの回動角度を１ノッチ毎に得られる節度に基づいて正確に知ることができるので、1 ノッチ毎の回動角度に基づいて捺印位置を微調整できることとなり、光沢紙のように適正な捺印位置の範囲が狭くても適正な捺印位置を高精度に設定できるものとなる。外套枠に対する印字体ユニットの印字面を捺印条件に応じた位置に的確に微調整できることとなる。 In particular, as a loosening prevention mechanism that prevents the adjustment knob from rotating, a slide member that is normally springed upward by a spring spring is incorporated so that its leg portion can slide up and down along the upper inner surface of the outer frame, A plurality of arc-shaped concave portions are provided on the top surface of the top plate portion of the slide member, while an engaging convex portion that engages with the arc-shaped concave portions is provided on the lower surface of the adjustment knob. As a result of this rotation, the engaging convex portion engages with any of the plurality of arc-shaped concave portions, so that the adjustment knob is rotated intermittently at a constant angle while providing moderation, and the outer cover frame is rotated. If the height of the printing unit is adjusted step by step to a predetermined amount, the screw rod is removed after the gripping member is removed in order to regulate the amount of contact of the printing surface with the surface to be printed when adjusting the printing density. 1 adjust knob screwed into If the print head unit is rotated, the height position of the print unit relative to the outer frame can be adjusted to finely adjust the printing surface position to a position according to the printing conditions. During this time, the rotation angle of the adjustment knob is 1 notch. Because it is possible to know accurately based on the moderation obtained each time, the stamping position can be finely adjusted based on the rotation angle for each notch, and even if the range of the appropriate stamping position is narrow like glossy paper A precise marking position can be set with high accuracy. The ability to accurately fine tune the position corresponding to the stamping condition the print surface of the print member unit against mantle frame.

さらに、調整ノブの下端縁にストッパを設ける一方、スライド部材の天板部上面に前記した調整ノブのストッパと係合して調整ノブの最大回動量を規制する係止部を備えたロックリングを取付けておけば、捺印濃度の調整範囲（最大濃度から最小濃度）を規制して最適化することができるうえに調整ノブの過剰な回動を防止できる。 Furthermore, while providing a stopper at the lower end edge of the adjustment knob, a lock ring provided with a locking portion that engages with the stopper of the adjustment knob and restricts the maximum amount of rotation of the adjustment knob on the top surface of the slide member. If attached, the adjustment range of the stamp density (maximum density to minimum density) can be regulated and optimized, and excessive rotation of the adjustment knob can be prevented.

次に、本発明の好ましい実施の形態を図に基づいて詳細に説明する。

また、印材カセット４は、図１、２に示されるように、受金４ｄにより印字体４ａとインキ吸蔵体４ｂとを支持したものであり、この印材カセット４の前後面には印材ホルダ５の前後内面に形成された横凸条５ｂ、５ｂと係合する横凹溝４ｃ、４ｃが形成されており、印材カセット４は横スライドさせることにより印材ホルダ５から簡単に着脱できるものとなっている。 As shown in FIGS. 1 and 2, the printing material cassette 4 supports the printing body 4a and the ink occlusion body 4b by a receiving metal 4d. Transverse grooves 4c and 4c are formed to engage with the lateral ridges 5b and 5b formed on the front and rear inner surfaces, and the printing material cassette 4 can be easily detached from the printing material holder 5 by laterally sliding. .

さらに、捺印圧調整機構７は、印材ホルダ５の中央頂部に立設したねじ棒８と、このねじ棒８に螺合されてその正逆回動により外套枠３に対する印字体ユニット１の高低位置を調整する調整ノブ１０とを少なくとも備えたものに調整ノブ１０の回動を阻止する緩み止め機構を組み込んであればよいが、図１および図２ａに示す実施態様において、緩み止め機構は、調整ノブ１０の外周面に形成してあるローレット１０ａと、把持部材６の内面に形成されて前記したローレット１０ａと係合する係止片６ｂとよりなるものとし、また、図２ａに示す他の実施態様においては、弾発ばね２により常時は上向きに弾発されるスライド部材９がその脚部を外套枠３の上部内面に添わせて上下摺動可能に組み込まれており、調整ノブ１０の回動を阻止する緩み止め機構が、このスライド部材９の天板部上面に配設した複数のノッチと、前記した調整ノブ１０の下面に設けられた係合用凸部９ａとよりなり、調整ノブ１０の回動により前記した係合用凸部９ａが複数のノッチのいずれかに係合してこれにより調整ノブ１０の回動操作が節度を付与しながら一定角度宛間欠的に行なわれて外套枠３に対する印字体ユニット１の高低位置が所定量宛段階的に調整されるようにしたものとしてある。 Further, the printing pressure adjusting mechanism 7 includes a screw rod 8 erected at the center top of the printing material holder 5 and a height position of the print unit 1 with respect to the outer frame 3 by being screwed to the screw rod 8 and rotating forward and backward. In the embodiment shown in FIGS. 1 and 2a, it is sufficient that a locking mechanism for preventing the rotation of the adjusting knob 10 is incorporated in at least the adjusting knob 10 for adjusting the locking mechanism. The knurl 10a formed on the outer peripheral surface of the knob 10 and the locking piece 6b formed on the inner surface of the gripping member 6 and engaged with the knurl 10a described above, and another embodiment shown in FIG. 2a. In the aspect, the slide member 9 that is normally urged upward by the elastic spring 2 is incorporated in such a manner that its leg portion is slidable up and down with the upper inner surface of the outer frame 3. Prevent movement The locking mechanism includes a plurality of notches disposed on the top surface of the top plate portion of the slide member 9 and an engaging convex portion 9a provided on the bottom surface of the adjusting knob 10. The above-described engaging convex portion 9a engages with any one of the plurality of notches, whereby the rotation operation of the adjustment knob 10 is intermittently performed at a fixed angle while giving moderation, and the printing body unit with respect to the outer frame 3 The height position of 1 is adjusted stepwise for a predetermined amount.

一方、前記した把持部材６は、上端に表示ラベルを拡大表示するレンズ部６ａを嵌着した角箱蓋形状のもので、把持部６の天井部中央の前後面には、図２に示されるように、調整ノブ１０の回動を阻止する緩み止め機構としての係止片６ｂ、６ｂが垂設されており、該係止片６ｂは把持部６を印字体ユニット１に嵌着することにより調整ノブ１０のローレット１０ａに係合されて、調整ノブ１０が不用意に回動することを防止している。 On the other hand, the above-described gripping member 6 has a rectangular box lid shape with a lens portion 6a for enlarging and displaying a display label on the upper end, and is shown in FIG. As described above, the locking pieces 6 b and 6 b as the locking mechanism for preventing the adjustment knob 10 from rotating are suspended, and the locking piece 6 b is attached by fitting the gripping part 6 to the printing body unit 1. The adjustment knob 10 is engaged with the knurl 10a of the adjustment knob 10 to prevent the adjustment knob 10 from rotating carelessly.

６ｃ、６ｃは図１に示されるように把持部６の天井部両側から垂設される押圧片であり、該押圧片６ｃは印材ホルダ５の角軸部５ａに捺印圧を加えるものである。６ｄ、６ｄは印材ホルダ５を把持部材６に係止させる保持板であり、該保持板６ｄには印材ホルダ５の角軸部５ａに形成される横隆条５ｃと係合する横溝６ｅが形成されていて、この横溝６ｅと横隆条５ｃとの係合により把持部材６は印材ホルダ５と一体化される。 As shown in FIG. 1, 6 c and 6 c are pressing pieces suspended from both sides of the ceiling portion of the gripping portion 6, and the pressing pieces 6 c apply a printing pressure to the square shaft portion 5 a of the printing material holder 5. Reference numerals 6d and 6d denote holding plates for locking the printing material holder 5 to the gripping member 6. The holding plate 6d is formed with a lateral groove 6e that engages with a horizontal ridge 5c formed on the square shaft portion 5a of the printing material holder 5. The gripping member 6 is integrated with the printing material holder 5 by the engagement between the lateral groove 6e and the lateral ridge 5c.

また、第１の実施態様に用いたスライド部材９は、図５、６に示されるように、調整ノブ１０の回動を阻止する緩み止め機構としても働くように、上面に７２°の角度で配設されるノッチに対応した大きさの４つの半球状の係合用凸部９ａと、この半球状の係合用凸部９ａより大きな直径で３６°間隔で透孔９ｂが透設されている。このように半球状の係合用凸部９ａとすることにより調整ノブ１０の円弧状凹部１０ｂとの係脱が円滑に節度をもって行なわれる。また、半球状の係合用凸部９ａは４つ設けられているが少なくとも一つあればよく、複数個設ける場合は３６°毎の角度で設けることはいうまでもない。９ｃは図５に示されるように、スライド部材９の両側外壁面に形成されるテーパ状の縦突条であり、該縦突条９ｃは図４に示されるように、外套枠３の凹部３ｂの側壁内面に形成されたテーパ状の縦溝３ｅと係合されることにより、スライド部材９を凹部３ｂに嵌めこむ際の作業が円滑に行なわれるようにしている。９ｄは外套枠３の凹部３ｂの上端縁と当接するようにスライド部材９の天板部周縁に形成されたフランジであり、図１、２に示されるように、該フランジ９ｄと凹部３ｂの上端縁間の間隔を調整することにより、捺印面の出没量を変えることができるようになっている。 Further, as shown in FIGS. 5 and 6, the slide member 9 used in the first embodiment has an upper surface at an angle of 72 ° so as to act as a loosening prevention mechanism that prevents the adjustment knob 10 from rotating. Four hemispherical engaging convex portions 9a having a size corresponding to the notches to be disposed, and through holes 9b are formed at intervals of 36 ° with a larger diameter than the hemispherical engaging convex portions 9a. Thus, by using the hemispherical engaging convex portion 9a, the adjustment knob 10 is smoothly engaged with and disengaged from the arc-shaped concave portion 10b. Further, although four hemispherical engaging convex portions 9a are provided, it is sufficient that at least one hemispherical engaging convex portion 9a is provided. As shown in FIG. 5, 9c is a tapered vertical ridge formed on the outer wall surfaces on both sides of the slide member 9, and the vertical ridge 9c is a recess 3b of the outer frame 3 as shown in FIG. By engaging with the tapered longitudinal groove 3e formed on the inner surface of the side wall, the operation when the slide member 9 is fitted into the recess 3b is smoothly performed. 9d is a flange formed on the periphery of the top plate portion of the slide member 9 so as to contact the upper edge of the recess 3b of the outer frame 3, and as shown in FIGS. 1 and 2, the upper end of the flange 9d and the recess 3b. By adjusting the distance between the edges, the amount of appearance of the stamped surface can be changed.

また、前記した調整ノブ１０のローレット１０ａは外周面にＶ字状凹部を１８°間隔に配設したもので、該Ｖ字状凹部は把持部６の前後面に対して直交するように配置され、把持部６の係止片６ｂと係合できるようになっている。さらに、調整ノブ１０の座面には節度付与機構１１の角度割出ノッチとしての１０個の円弧状凹部１０ｂが３６°間隔に形成され、スライド部材９の上面に形成された節度付与機構１１としての円弧状凸起９ａと弾発ばね２の弾発力により係脱されるようになっている。このため調整ノブ１０の回動操作は３６°毎節度をもって行なわれる。また、調整ノブ１０の雌ねじ１０ｃは０．５ｍｍピッチとしているため、調整ノブ１０を３６°回動させるとフランジ９ｄと凹部３ｂの上端縁との間隔は０．０５ｍｍ間隔で狭くなったり、拡がったりする。この調整は８段階で行なわれるため、最大０．４ｍｍ捺印面を出没させることができる。なお、雌ねじ１０ｃのピッチは０．５ｍｍピッチに限定されるものではなく、紙の種類はインキの種類に応じて細かいピッチとしたり荒いピッチとしたりすればよいことはいうまでもない。 The knurl 10a of the adjustment knob 10 described above has V-shaped concave portions arranged at intervals of 18 ° on the outer peripheral surface, and the V-shaped concave portions are arranged so as to be orthogonal to the front and rear surfaces of the grip portion 6. The engaging piece 6b of the grip 6 can be engaged. Further, ten arc-shaped recesses 10b as angle indexing notches of the moderation providing mechanism 11 are formed on the seating surface of the adjustment knob 10 at intervals of 36 °, and the moderation providing mechanism 11 formed on the upper surface of the slide member 9 is formed. The arcuate protrusion 9a and the elastic force of the elastic spring 2 are engaged and disengaged. For this reason, the turning operation of the adjustment knob 10 is performed with a moderation of 36 °. Further, since the internal thread 10c of the adjustment knob 10 has a pitch of 0.5 mm, when the adjustment knob 10 is rotated by 36 °, the distance between the flange 9d and the upper edge of the recess 3b is narrowed or widened by 0.05 mm. To do. Since this adjustment is performed in eight stages, a maximum 0.4 mm marking surface can be made to appear and disappear. Needless to say, the pitch of the female screw 10c is not limited to a 0.5 mm pitch, and the type of paper may be fine or rough depending on the type of ink.

また、捺印位置の調整８を段階状とするのは、調整ノブ１０のストッパ１２が１８°の開き角度で形成され、後記するロックリング１３の係止部１３ｂが５０．６°の開き角度で形成されるため、３６０°のうち約７０°の角度は不使用領域となるからである。１０ｄはストッパ位置に形成されて捺印が濃くなるほうに回動されたのか薄くなるほうに回動されたかを視認するための凸状の矢印表示である。 Further, the stamping position adjustment 8 is made stepwise because the stopper 12 of the adjustment knob 10 is formed with an opening angle of 18 °, and a locking portion 13b of the lock ring 13 to be described later has an opening angle of 50.6 °. This is because an angle of about 70 ° out of 360 ° becomes a non-use area. Reference numeral 10d denotes a convex arrow display for visually confirming whether it has been rotated at a position where the stamp is darker or thinner.

前記調整ノブ１０の座面周縁部に形成されるストッパ１２は後記ロックリング１３の係止部１３ｂと係止されて調整ノブ１０の回動範囲が３６０°以内となるようにするものである。前記したロックリング１３には爪付の係止脚１３ａを対向垂設するとともに、前記した調整ノブ１０に形成されるストッパ１２と当接する係止部１３ｂを内周面に形成している。係止脚１３ａは前記スライド部材９の３６°間隔で透設された任意の透孔９ｂに嵌合することにより、ロックリング１３の取り付け位置を変えることができるようにして、捺印濃度の調整範囲（最大濃度から最小濃度）を最適化することができるようになっている。 A stopper 12 formed on the peripheral edge of the seating surface of the adjustment knob 10 is engaged with an engagement portion 13b of a lock ring 13 to be described later so that the rotation range of the adjustment knob 10 is within 360 °. The lock ring 13 is provided with an engaging leg 13a with a nail facing the lock ring 13, and an engaging portion 13b that contacts the stopper 12 formed on the adjusting knob 10 is formed on the inner peripheral surface. The locking leg 13a can be fitted into arbitrary through holes 9b provided at intervals of 36 ° of the slide member 9, so that the mounting position of the lock ring 13 can be changed, and the adjustment range of the printing density. (Maximum density to minimum density) can be optimized.

前記した弾発ばね２は、上端をスライド部材９の天井面に当接させるとともに下端を外套枠３の凹部３ｂの内底面に当接させている。１４は印材カセット４に係合される印面キャップであり、該印面キャップ１４は印材カセット４の下端縁を受ける係止段部１４ｂが両側に形成されて、印字体４ａが印面キャップ１４の内面に接触しないようにしている。 The above-described elastic spring 2 has an upper end in contact with the ceiling surface of the slide member 9 and a lower end in contact with the inner bottom surface of the recess 3 b of the outer frame 3. Reference numeral 14 denotes a printing surface cap that is engaged with the printing material cassette 4. The printing surface cap 14 is formed with locking step portions 14 b that receive the lower edge of the printing material cassette 4 on both sides, and the printing body 4 a is formed on the inner surface of the printing surface cap 14. I try not to touch it.

このように構成されたものは、印字体ユニット１が、下端に多孔性印材が収納されるとともに中央頂部にねじ棒８が立設された印材ホルダ５と、天板部に形成された中心孔を前記したねじ棒８に遊挿させた状態で前記した外套枠３の内部に形成されたスライドガイド用の凹部３ｂに嵌入されて弾発ばね２により常時は前記した天板部の周縁のフランジ９ｄと外套枠３の内部に形成されるストッパ部との間に所要の隙間が形成されるように上向きに弾発されているスライド部材９と、このスライド部材９の上部に着脱自在に嵌装された把持部材６とよりなるものであるから、常時は外套枠の内側に昇降動自在に装着した印字体ユニット１の印字面が弾発ばね２によって常時は外套枠の脚端よりやや上方に位置されていて印字面により他物を汚すおそれがなく、また、捺印時には弾発ばね２の弾発力に抗して印字体ユニット１を押し下げるだげで捺印できることは従来のこの種の印判と同様であるが、例えば、光沢紙に捺印を行なう場合のようにインキの付着量が多いとインキの乾燥に時間がかかり机上を乾燥させるための捺印書類が占有して仕事ができなくなったり、捺印を行なった直後に不用意に書類を重ね合わせると、捺印面のインキが重ね合わせた上側の紙の裏面に付着する裏移りを生じさせたり、紙を束ねて整列させる際、インキがこすれて捺印が不鮮明になったり、インクの付着量が少なくて、捺印面がかすれて読み難くかったりするので、このようなときには、先ず、把持部材６を印材ホルダ５から外して、調整ノブ１０を露呈させる。 What is configured in this manner is that the printing body unit 1 includes a printing material holder 5 in which a porous printing material is stored at the lower end and a screw rod 8 is erected at the center top, and a center hole formed in the top plate portion. Is inserted into a slide guide recess 3b formed inside the outer casing 3 in a state of being loosely inserted into the screw rod 8 and is always flanged on the periphery of the top plate by the elastic spring 2. A slide member 9 that is bounced upward so that a required gap is formed between 9d and a stopper portion formed inside the outer casing frame 3, and is detachably fitted to the upper portion of the slide member 9 Therefore, the printing surface of the printing unit 1 that is normally mounted on the inner side of the outer frame so as to be movable up and down is always slightly above the leg end of the outer frame by the elastic spring 2. It is located and stains other things by the printing surface There is no such thing, and it is possible to print by pressing down the printing body unit 1 against the resilience of the spring 2 at the time of stamping. If the amount of ink adhering is large as in the case of performing printing, it takes time to dry the ink and the stamped document for drying the desk is occupied, making it impossible to work, or inadvertently stacking documents immediately after stamping If they are combined, the ink on the stamped surface will be transferred to the back side of the upper paper, or when the paper is bundled and aligned, the ink will be rubbed and the stamp may become unclear, At least in this case, the marking surface is faint and difficult to read. In such a case, the gripping member 6 is first removed from the printing material holder 5 and the adjustment knob 10 is exposed.

次に、調整ノブ１０を正回転あるいは逆回転させれば、調整ノブ１０は印材ホルダ５のねじ棒８にねじ込まれるかねじ戻されるので、スライド部材９は外套枠３の凹部３１内で上下スライドすることなり、スライド部材９のフランジ９ｄと外套枠３の凹部３ｂ上端縁間の間隔は調整され、これにより印字体４ａの出没量は変更され、インキの付着量が調整されることとなる。 Next, when the adjustment knob 10 is rotated forward or backward, the adjustment knob 10 is screwed into or unscrewed from the screw rod 8 of the printing material holder 5, so that the slide member 9 slides up and down within the recess 31 of the outer frame 3. Thus, the distance between the flange 9d of the slide member 9 and the upper edge of the recess 3b of the outer frame 3 is adjusted, whereby the amount of appearance of the printed body 4a is changed, and the amount of ink adhering is adjusted.

このとき、調整ノブ１０は３６°間隔で回動されるので、ねじ棒８は０．５ｍｍピッチとしているため、３６°回動させれば０．０５ｍｍ単位で印面を上下動させ、インキの付着量を微調整することができる。 At this time, since the adjustment knob 10 is rotated at an interval of 36 °, the screw rod 8 is set at a pitch of 0.5 mm. The amount can be fine-tuned.

このようにして調整を行なったうえ、把持部材６を印材ホルダ５に係合させれば、調整ノブ１０のＶ字状凹部に把持部材６の係止片６ｂ、６ｂが係合されるので、調整ノブ１０は完全に動き止めされることとなる。 If the gripping member 6 is engaged with the printing material holder 5 after adjusting in this way, the locking pieces 6b, 6b of the gripping member 6 are engaged with the V-shaped recess of the adjustment knob 10. The adjustment knob 10 is completely stopped.

この状態で捺印を行なってインキの付着量を確かめ、付着量が多すぎたり少なすぎたりしたら、前記と同様にして印面の張出量を変えて調整を行なえばよい。このようにして適正なインキの付着量が得られれば、たとえ被捺印面が光沢紙であっても、インキの乾燥は速くなるので、捺印を行なった書類を机上に広げてインキを乾燥させる必要がなくなるので、仕事を迅速且つ円滑にこなすことができるものとなる。 In this state, stamping is performed to confirm the amount of ink deposited. If the amount of ink deposited is too large or too small, adjustment may be performed by changing the protruding amount of the printing surface in the same manner as described above. If an appropriate amount of ink is obtained in this way, the ink will dry faster even if the surface to be printed is glossy paper, so it is necessary to spread the printed document on the desk and dry the ink. Therefore, work can be performed quickly and smoothly.
