特許文献1に記載された発明では、底板上にピン位置決め板を配置すると共に、頭部と同じ径の第1柱部と第1柱部より径の大きな第2柱部からなる刻印ピンの第2柱部をピン位置決め板の所定の貫通孔に挿入し、ピン位置決め板から上方へ進出する第1柱部が挿入できる貫通孔を有する抜け防止板をピン位置決め板の上に載せて刻印ピンを所定位置に保持している。刻印すべき点字を変更しようとする場合、抜け防止板をピン位置決め板から外し、ピン位置決め板に配置されている刻印ピンを抜き、新たな所定の貫通孔に刻印ピンを挿入し、再び抜け防止板をピン位置決め板の上に載せる必要があることから、ピン位置決め板に刻印ピンを配置する作業に手間取り、煩雑である。   In the invention described in Patent Document 1, a pin positioning plate is arranged on the bottom plate, and the first pin of the marking pin including the first pillar portion having the same diameter as the head portion and the second pillar portion having a larger diameter than the first pillar portion. Insert the two pillars into the predetermined through-holes of the pin positioning plate, and place the anti-separation plate with the through holes into which the first pillars can be inserted. It is held in place. When changing the braille to be engraved, remove the prevention plate from the pin positioning plate, remove the engraving pin located on the pin positioning plate, insert the engraving pin into a new predetermined through hole, and prevent it from coming off again. Since it is necessary to place the plate on the pin positioning plate, it is troublesome and troublesome to arrange the marking pins on the pin positioning plate.

特許文献2に記載された発明では、フランジ付き刻印ピンをピン位置決め板の下方から所定の貫通孔に挿入してフランジを貫通孔の縁に突き当てると共に、ピン位置決め板を底板上に置いてピン位置決め板を底板にねじ止めし、ピンを所定位置に保持している。刻印すべき点字を変更しようとする場合、ねじを緩めてピン位置決め板を底板から外し、ピン位置決め板に配置されているピンを抜き、新たな所定の貫通孔に刻印ピンを挿入し、再びピン位置決め板を底板上に置いてピン位置決め板を底板にねじ止めする必要があることから、ピン位置決め板の底板への着脱作業やピン位置決め板への刻印ピンの配置作業に手間取り、煩雑である。加えて、ピンにフランジを設けているため、ピンの加工に時間がかかる。   In the invention described in Patent Document 2, a marking pin with a flange is inserted into a predetermined through hole from below the pin positioning plate, the flange is abutted against the edge of the through hole, and the pin positioning plate is placed on the bottom plate to pin the pin The positioning plate is screwed to the bottom plate and the pin is held in place. If you want to change the braille to be engraved, loosen the screw, remove the pin positioning plate from the bottom plate, remove the pin located on the pin positioning plate, insert the engraving pin into the new predetermined through hole, and pin again Since it is necessary to place the positioning plate on the bottom plate and screw the pin positioning plate to the bottom plate, it is troublesome to attach and detach the pin positioning plate to the bottom plate and to place the marking pins on the pin positioning plate. In addition, since the flange is provided on the pin, it takes time to process the pin.

この発明の目的は、ピン位置決め板の所定位置への刻印ピンの配置を速やかに行うことができ、煩雑さを減らすことができる点字刻印器を提供することにある。   An object of the present invention is to provide a braille stamp that can quickly place a marking pin at a predetermined position of a pin positioning plate and reduce complexity.

この目的を達成するためにこの発明は、次の構成を備え、作用効果を奏する。なお、何れかの請求項記載の発明の構成等を説明するに当って行う用語の定義等は、その性質状可能な範囲において他の請求項記載の発明にも適用があるものとする。   In order to achieve this object, the present invention has the following configuration and exhibits operational effects. It should be noted that the definitions of terms used to describe the structure and the like of the invention described in any claim are also applicable to the invention described in other claims as long as the properties are possible.

請求項1記載の発明に係る点字刻印器は、点字を横方向に連ねて、又は縦方向に連ねて被刻印シートに刻印するものであり、各点字を構成する複数のドット位置を少なくとも3つ又は少なくとも2つのドット位置を含むグループに分け、各グループに含まれる少なくとも3つ又は少なくとも2つのドット位置を、点字を連ねる方向と実質的に直交する方向に配置すると共に、複数のドット位置に貫通孔を開けて一文字区画を形成し、この一文字区画を、点字を連ねる方向へ1又は複数配列したピン位置決め板と、前記すべての貫通孔に挿入配置した刻印ピンであって、各刻印ピンの頭部がピン位置決め板の上面から上方へ進出する位置とピン位置決め板の上面から退去する位置とをとる刻印ピンと、前記ピン位置決め板の下方に間隔をおいて配置される基盤と、前記少なくとも3つ又は少なくとも2つのドット位置のグループ毎にドット位置に対応して前記基盤に配置されるスライド板であって、前記グループ内の貫通孔に配置した前記刻印ピンの進出と退去を定める凸面及び凹面を刻印ピンに対向する上面に有し、上面の長さ方向へ移動可能に支持されるスライド板と、前記刻印ピンの頭部が被刻印シートと共に挿入可能である複数の凹部を前記複数の貫通孔に対応する位置に形成した押圧板であって、前記ピン位置決め板の上方に配置され、前記基盤と相俟って前記ピン位置決め板及び前記スライド板をはさむ押圧板と、前記押圧板を上下方向へ移動させる昇降機構とを備えることを特徴とする。
(Characteristics of the invention of claim 1)
The braille marking device according to the first aspect of the present invention is an apparatus for marking braille on a sheet to be stamped by connecting the braille in the horizontal direction or in the vertical direction, and has at least three dot positions constituting each braille. Or, it is divided into a group including at least two dot positions, and at least three or at least two dot positions included in each group are arranged in a direction substantially perpendicular to the direction in which the braille is connected, and penetrated to a plurality of dot positions. A single character section is formed by opening a hole, and a pin positioning plate in which the one character section is arranged in a direction in which brailles are connected, and a marking pin inserted and arranged in all the through holes, each having a head. A marking pin that takes a position where the portion moves upward from the upper surface of the pin positioning plate and a position where the portion moves away from the upper surface of the pin positioning plate, and is spaced below the pin positioning plate A base plate to be placed and a slide plate disposed on the base corresponding to a dot position for each group of the at least three or at least two dot positions, the marking pin disposed in a through hole in the group Has a convex surface and a concave surface that determine the advance and retreat of the marking plate on the upper surface facing the marking pin, and is supported so as to be movable in the length direction of the upper surface, and the head of the marking pin can be inserted together with the stamped sheet. A pressing plate in which a plurality of concave portions are formed at positions corresponding to the plurality of through-holes, and is disposed above the pin positioning plate and sandwiches the pin positioning plate and the slide plate together with the base. It is provided with a pressing plate and an elevating mechanism for moving the pressing plate in the vertical direction.

現在一般的に使用されている点字は6点式点字であり、縦二列で各列に3つのドット位置を配置した各点字は通常の文字と同様に、上下関係や左右関係が定まっている。そこで、同一の点字刻印器を使用して点字を横方向に連ねて刻印する、いわゆる横書きの場合と、点字を縦方向に連ねて刻印する、いわゆる縦書きの場合とでは、点字の向きを変える必要がある。通常、横書きの場合も縦書きの場合も、一文字区画を横方向に配列して刻印する形態、いわゆる横打ち横書きタイプ、また横打ち縦書きタイプが採用される。そこで、横書きの場合には、各グループに3つのドット位置を含ませて一文字区画を2つのグループで構成する。また縦書きの場合には、各グループに2つのドット位置を含ませて一文字区画を3つのグループで構成する。そして、凸面及び凹面の位置を3つのドット位置に対応するように形成したスライド板、又は2つのドット位置に対応するように形成したスライド板を使用することにより横書きと縦書きに対処できる。   The Braille currently in common use is a 6-point Braille, and each braille with three dots arranged in each row in two vertical rows has a vertical and horizontal relationship similar to normal characters. . Therefore, the direction of Braille is changed between so-called horizontal writing, in which Braille is printed in the horizontal direction using the same Braille stamp, and so-called vertical writing in which Braille is printed in the vertical direction. There is a need. Normally, in both horizontal writing and vertical writing, a form in which one character section is arranged in the horizontal direction and engraved, a so-called horizontal writing type or horizontal writing vertical writing type is employed. Therefore, in the case of horizontal writing, each group includes three dot positions, and one character section is composed of two groups. In the case of vertical writing, each group includes two dot positions, and one character section is configured by three groups. By using a slide plate formed so that the positions of the convex surface and the concave surface correspond to three dot positions, or a slide plate formed so as to correspond to two dot positions, horizontal writing and vertical writing can be dealt with.

6つ以外の複数のドット位置、例えば8つのドット位置で各点字を構成する特殊な要請に対処することもできる。横書きの場合には、各グループに4つのドット位置を含ませて一文字区画を2つのグループで構成する。また縦書きの場合には、各グループに2つのドット位置を含ませて一文字区画を4つのグループで構成する。さらに、9つのドット位置で各点字を構成する要請に対処することもできる。横書きの場合には、各グループに3つのドット位置を含ませて一文字区画を3つのグループで構成する。また縦書きの場合には、各グループに3つのドット位置を含ませて一文字区画を3つのグループで構成する。   It is also possible to cope with a special requirement that each braille is composed of a plurality of dot positions other than six, for example, eight dot positions. In the case of horizontal writing, each group includes four dot positions, and one character section is composed of two groups. In the case of vertical writing, each group includes two dot positions, and one character section is configured by four groups. Further, it is possible to cope with a request for configuring each braille with nine dot positions. In the case of horizontal writing, each group includes three dot positions, and one character section is composed of three groups. In the case of vertical writing, each group includes three dot positions, and one character section is constituted by three groups.

請求項1の点字刻印器によれば、刻印ピンをすべての貫通孔に予め配置してあるため、刻印すべき点字を変更する場合でも、ピン位置決め板から刻印ピンを抜いたり、ピン位置決め板に刻印ピンを再配置したりする手間が不要となり、速やかな変更が期待できる。また、スライド板を移動して刻印ピンの進出と退去を行わせて所定の点字をうるため、煩雑さは少ない。   According to the braille marking device of claim 1, since the marking pins are arranged in advance in all the through holes, even when the braille to be stamped is changed, the marking pin is removed from the pin positioning plate, The need for rearranging the engraving pins is unnecessary, and prompt changes can be expected. Further, since the slide plate is moved to advance and retreat the marking pin to obtain a predetermined Braille, there is little complexity.

(請求項2記載の発明の特徴)
請求項2記載の発明に係る点字刻印器は、請求項1の点字刻印器の基本構成に加え、前記刻印ピンは磁力によって前記ピン位置決め板に仮に保持されることを特徴とする。
(Characteristics of the invention described in claim 2)
In addition to the basic configuration of the Braille stamper according to the first aspect, the Braille stamper according to the second aspect of the present invention is characterized in that the stamping pin is temporarily held on the pin positioning plate by a magnetic force.

仮に保持されるとは、刻印ピンの頭部がピン位置決め板の上面から退去しているか、又は上方へ進出していても、わずかな力によって退去する状態をいう。刻印ピンの例えば、下方部分に磁石を埋設するか、又は刻印ピンの全体を磁石で作ると共に、ピン位置決め板を強磁性材料で作る。この場合の磁力は、刻印ピンを仮に保持することができる大きさでよい。   “Temporarily held” refers to a state in which the head of the marking pin has moved away from the upper surface of the pin positioning plate or moved upward with a slight force even if it has advanced upward. For example, a magnet is embedded in the lower portion of the marking pin, or the entire marking pin is made of a magnet, and the pin positioning plate is made of a ferromagnetic material. The magnetic force in this case may be large enough to temporarily hold the marking pin.

請求項2の点字刻印器によれば、刻印ピンが磁力によってピン位置決め板に仮に保持されるため、ピン位置決め板を基盤上に組み込むときや、点字刻印器をある場所から別の場所へ移すときなどに、刻印ピンが脱落するのを防ぐことができる。   According to the braille marking device of claim 2, since the marking pin is temporarily held by the pin positioning plate by magnetic force, when the pin positioning plate is incorporated on the base, or when the braille stamping device is moved from one place to another. For example, the engraving pin can be prevented from falling off.

(請求項3記載の発明の特徴)
請求項3記載の発明に係る点字刻印器は、請求項1の点字刻印器の基本構成に加え、前記刻印ピンは前記頭部と、頭部から下方へ延びる第1柱部と、第1柱部から境界面を介して下方へ延びる、第1柱部より外径の小さな第2柱部とからなり、前記ピン位置決め板の前記貫通孔は、第1柱部が摺動する第1孔部と、第1孔部から肩を介して下方へ延びる、第1孔部より内径の小さな、第2柱部が摺動する第2孔部とからなり、前記刻印ピンは前記境界面を前記肩に載せて仮に保持されることを特徴とする。
(Characteristics of Claim 3)
According to a third aspect of the present invention, in addition to the basic configuration of the first aspect of the braille stamper, the marking pin includes the head, a first column portion extending downward from the head, and a first column. A first pillar part extending downward from the part through a boundary surface and having a smaller outer diameter than the first pillar part, and the through hole of the pin positioning plate is a first hole part on which the first pillar part slides And a second hole part extending downward from the first hole part through the shoulder and having a smaller inner diameter than the first hole part, and the second column part sliding, wherein the marking pin extends the boundary surface over the shoulder part. It is characterized by being put on and temporarily held.

第1柱部と第2柱部は、刻印ピンが境界面を肩に載せて仮に保持されるとき、第2柱部の下方部分がピン位置決め板の下面から下方へ進出するように、かつ、進出した第2柱部の下方部分がスライド板の凸面によって上方へ押し上げられるとき、刻印ピンの頭部がピン位置決め板の上面から上方へ進出して適切な位置をとるように、全体的に長さを定める。第1柱部が第2柱部より長くても、同じでも、短くてもよい。   The first pillar part and the second pillar part, when the marking pin is temporarily held with the boundary surface on the shoulder, the lower part of the second pillar part advances downward from the lower surface of the pin positioning plate, and When the lower part of the advanced second pillar part is pushed upward by the convex surface of the slide plate, the overall length is long so that the head of the marking pin advances upward from the upper surface of the pin positioning plate and takes an appropriate position. Determine the size. The first pillar part may be longer, the same or shorter than the second pillar part.

請求項3の点字刻印器によれば、刻印ピン及びピン位置決め板の貫通孔の機械加工による、いわゆる相補形状によって刻印ピンを仮に保持するため、刻印ピン及びピン位置決め板それぞれの強度が保たれる限り、刻印ピンやピン位置決め板を種種の材料で作ることができる。   According to the braille marking device of claim 3, since the marking pin is temporarily held by a so-called complementary shape by machining the through hole of the marking pin and the pin positioning plate, the strength of the marking pin and the pin positioning plate is maintained. As long as the marking pin and pin positioning plate can be made of various materials.

(請求項4記載の発明の特徴)
請求項4記載の発明に係る点字刻印器は、請求項1乃至3何れかの点字刻印器の基本構成に加え、前記スライド板は、前記ピン位置決め板をはさむように前記スライド板の移動方向に間隔をおいて配置され、ピン位置決め板に突き当たる一対のストッパを備え、これらストッパは、前記スライド板の凸面及び凹面が前記刻印ピンを進出及び退去させるのに必要なスライド板の移動距離より大きな間隔で位置することを特徴とする。
(Feature of the invention of claim 4)
According to a fourth aspect of the present invention, in addition to the basic configuration of the first aspect of the first to third aspects, the slide plate moves in the moving direction of the slide plate so as to sandwich the pin positioning plate. A pair of stoppers arranged at intervals and abutting against the pin positioning plate are provided, and these stoppers are larger than the moving distance of the slide plate necessary for the convex surface and concave surface of the slide plate to advance and retract the marking pin. It is located in.

ストッパはスライド板と一体に作ることもでき、また別個に作ったものをスライド板に接着、溶接等によって取りつけることもできる。   The stopper can be made integrally with the slide plate, or a separately made stopper can be attached to the slide plate by bonding, welding or the like.

請求項4の点字刻印器によれば、スライド板は前後方向へ進退するところ、一対のストッパを、ピン位置決め板をはさんで配置してあり、その間隔をスライド板の移動距離より大きくしてあるため、スライド板が前方へ進出しても、後方へ退出してもスライド板の抜けを防ぐことができる。また、ストッパがスライド板の機能を損なうことがない。   According to the braille marking device of claim 4, when the slide plate advances and retreats in the front-rear direction, the pair of stoppers are arranged between the pin positioning plates, and the distance between them is larger than the moving distance of the slide plate. Therefore, it is possible to prevent the slide plate from coming off even if the slide plate advances forward or exits backward. Further, the stopper does not impair the function of the slide plate.

(請求項5記載の発明の特徴)
請求項5記載の発明に係る点字刻印器は、請求項1乃至4何れかの基本構成に加え、前記スライド板はスライド板の移動方向に等間隔をおいた複数の切欠きを下面に有し、前記基盤は、上方の進出位置に向けて偏倚され、進出位置で前記切欠きに嵌まるストッパピンを備え、当該ストッパピンはスライド板を移動させる力によって下方へ退去することを特徴とする。
(Feature of the invention of claim 5)
According to a fifth aspect of the present invention, in addition to the basic structure of any one of the first to fourth aspects, the slide plate has a plurality of notches on the lower surface at equal intervals in the moving direction of the slide plate. The base plate is provided with a stopper pin that is biased toward an upper advance position and fits into the notch at the advance position, and the stopper pin is moved downward by a force that moves the slide plate.

スライド板の複数の切欠きは、切欠き間の間隔はスライド板の1ピッチ、つまりスライド板がある距離移動したとき、ある凸面又は凹面と係合していた各グループ内の各刻印ピンが別の凸面又は凹面と係合するようになる距離と等しいことが好ましい。しかし、切欠き間の間隔をスライド板の1ピッチの整数倍分の1に定めることもできる。例えば、スライド板が1ピッチ移動したとき、ストッパピンが2つの切欠きと係合するように定めることもできる。ストッパピンはばねによって進出位置に向けて偏倚させる。そのばねのばね力は、スライド板を移動させる力によってストッパピンが下方へ退去することができるような大きさである。   The notches on the slide plate are separated by one pitch of the slide plate, that is, when the slide plate moves a certain distance, each marking pin in each group engaged with a certain convex surface or concave surface is different. It is preferable that it is equal to the distance which comes to engage with the convex surface or concave surface. However, the interval between the notches can be set to an integral multiple of one pitch of the slide plate. For example, when the slide plate is moved by one pitch, it can be determined that the stopper pin is engaged with two notches. The stopper pin is biased toward the advanced position by a spring. The spring force of the spring is such a magnitude that the stopper pin can be moved downward by a force that moves the slide plate.

請求項5の点字刻印器によれば、スライド板を移動するとき、ストッパピンが切欠きに嵌まるカチカチ音が生ずることから、そのカチカチ音を数えることでスライド板が何ピッチ動いたかを確認できる。視認によって各刻印ピンの進出、退去状況を確認することができるが、視認できない場合にはカチカチ音でスライド板のピッチ数を確認し、そのピッチ数から刻印ピンの進出、退去状況を推量する。   According to the braille marking device of claim 5, when the slide plate is moved, a ticking sound that the stopper pin fits into the notch is generated, so that it is possible to confirm how many pitches the slide plate has moved by counting the ticking sound. . Although the advancement and withdrawal status of each marking pin can be confirmed by visual recognition, if the visual recognition cannot be performed, the number of pitches of the slide plate is confirmed by a ticking sound, and the advancement and withdrawal status of the marking pin is estimated from the pitch number.

(請求項6記載の発明の特徴)
請求項6記載の発明に係る点字刻印器は、請求項1乃至5何れかの基本構成に加え、前記昇降機構は、前記基盤に設けた支持台に上下方向へ移動可能に支持され、前記押圧板を固定する昇降材と、前記支持台に回転可能に支持される枢軸に固定される取っ手付きアームと、アームの枢軸回りの回転を昇降材に伝達する手段とを備えることを特徴とする。
(Characteristics of the invention described in claim 6)

支持台に2つの枢軸を取りつけて各枢軸にアームを固定し、これらアームを取っ手で結合した、いわゆるコ字形タイプにするか、又は単一のアームに取っ手を結合した、いわゆるT形タイプにする。昇降材はばね又は空気シリンダによって上方へ向けて偏倚させることが好ましい。枢軸にピニオンを固定し、昇降材にピニオンとかみ合うラックを取りつけてアームの回転を昇降材の上下運動として伝達する。その他、アーム及び昇降材に枢軸で連結したリンクを使用してアームの回転を昇降材の上下運動として伝達することができる。   Two pivots are attached to the support base and the arms are fixed to the respective pivots, and these arms are connected to each other by a so-called U-shaped type, or a single arm is connected to a so-called T-type. . The lifting material is preferably biased upward by a spring or an air cylinder. A pinion is fixed to the pivot, and a rack meshing with the pinion is attached to the lifting material, and the rotation of the arm is transmitted as the vertical motion of the lifting material. In addition, the rotation of the arm can be transmitted as the up-and-down motion of the lifting / lowering material using a link connected to the arm and the lifting / lowering material by a pivot.

請求項6の点字刻印器によれば、取っ手付きアームによって昇降材を上下させ、昇降材と共に押圧板を上下させるため、操作が簡単である。   According to the braille marking device of the sixth aspect, since the lifting material is moved up and down by the arm with the handle and the pressing plate is moved up and down together with the lifting material, the operation is simple.

(First embodiment of pin positioning plate)
The pin positioning plate 1 in FIG. 1 has a plurality of single character sections 3 surrounded by a two-dot chain line. This two-dot chain line conceptually shows the area occupied by the character section 3 (the same applies in the second embodiment described later). Each character section 3 divides six dot positions 5 into two groups 3 a and 5 b arranged vertically, and each dot position 5 has a through-hole 5 h that penetrates in the thickness direction of the pin positioning plate 1. It is. A dot position 5 indicates a position where the through hole 5h is formed. That is, the dot position 5 is the through hole 5h itself. The dot positions 5 of each group are arranged in the vertical direction, which is substantially perpendicular to the horizontal writing direction in this embodiment, in this embodiment, and through holes 5h are formed at the six dot positions as described above.

刻印ピン9はピン位置決め板1のすべての貫通孔5h,・・に配置する。図1では20個の一文字区画3をピン位置決め板1に配列しているため、合計120本の刻印ピン9を使用している。刻印ピン9は、図3の矢印Aで示すように外力を受けて上下に動き、各刻印ピン9の頭部9aがピン位置決め板1の上面1aから上方へ進出する位置と、ピン位置決め板1の上面1aから退去する位置とをとる。退去した刻印ピン9の下方部分は、ピン位置決め板1の下面1bから下方へ進出する。すなわち、各刻印ピン9は、貫通孔5h内を上下方向(ピン位置決め板1の厚み方向)に移動可能に構成してある。図3ではグループ内の3つの貫通孔5hそれぞれに刻印ピン9を挿入してあり、中央の刻印ピン9の頭部9aが上方へ進出し、左右の刻印ピン9の頭部が退去している。刻印ピン9の頭部9aは進出方向に丸い半球状であり、従来の点字刻印器と同様に、被刻印シートに適切な凸を刻印することができる。   The marking pins 9 are arranged in all the through holes 5h of the pin positioning plate 1. In FIG. 1, since 20 one-character sections 3 are arranged on the pin positioning plate 1, a total of 120 marking pins 9 are used. The marking pin 9 receives an external force and moves up and down as indicated by an arrow A in FIG. 3, a position where the head 9 a of each marking pin 9 advances upward from the upper surface 1 a of the pin positioning plate 1, and the pin positioning plate 1. And a position for leaving the upper surface 1a. The lower part of the marking pin 9 that has moved out advances downward from the lower surface 1 b of the pin positioning plate 1. That is, each marking pin 9 is configured to be movable in the vertical direction (the thickness direction of the pin positioning plate 1) in the through hole 5h. In FIG. 3, the marking pin 9 is inserted into each of the three through holes 5h in the group, the head 9a of the central marking pin 9 has advanced upward, and the heads of the left and right marking pins 9 have retreated. . The head 9a of the marking pin 9 has a round hemispherical shape in the advancing direction, and an appropriate convex can be stamped on the sheet to be stamped in the same manner as a conventional braille stamp.

(ピン位置決め板の第二の実施形態)
図4のピン位置決め板11は、二点鎖線で囲った複数の一文字区画13を有する。各一文字区画13は、6つのドット位置15を縦に並ぶ2個ずつ3つのグループ15a,15b,15cに分け、各ドット位置15には、ピン位置決め板11の厚み方向に貫通する貫通孔15hを開けてある。ドット位置15は、貫通孔15hを形成する位置を示す。つまり、ドット位置15は貫通孔15hそのものである。各グループのドット位置15を、点字を連ねる方向、この実施形態では縦書きの左右方向と実質的に直交(略直交)する上下方向に配置し、6つのドット位置に上述したように貫通孔15hを開けて形成してある。複数の一文字区画13は左右方向に等間隔をおいて配列する。図4に示すピン位置決め板11には、被刻印シートの読み面に左端から右方にむけてア、イ、ウ、エ、オが刻印されるように、進出した刻印ピンを黒丸で示してある。ピン位置決め板11の全体の寸法や形状は位置決め板1と同じであり、ピン位置決め板11は左右(長手方向)の側部にそれぞれ厚み方向に貫通する2つのねじ孔7を有する。
(Second embodiment of pin positioning plate)
The pin positioning plate 11 in FIG. 4 has a plurality of single character sections 13 surrounded by a two-dot chain line. Each character section 13 divides six dot positions 15 into two groups 15 a, 15 b, and 15 c arranged vertically, and each dot position 15 has a through hole 15 h that penetrates in the thickness direction of the pin positioning plate 11. It is open. The dot position 15 indicates a position where the through hole 15h is formed. That is, the dot position 15 is the through hole 15h itself. The dot positions 15 of each group are arranged in a direction in which brailles are connected, in this embodiment, in a vertical direction that is substantially perpendicular (substantially orthogonal) to the horizontal direction of vertical writing, and through holes 15h as described above at six dot positions. It is formed by opening. The plurality of single character sections 13 are arranged at equal intervals in the left-right direction. In the pin positioning plate 11 shown in FIG. 4, the advancing marking pin is indicated by a black circle so that a, i, c, d, and o are engraved from the left end to the right side on the reading surface of the engraved sheet. is there. The overall dimensions and shape of the pin positioning plate 11 are the same as those of the positioning plate 1, and the pin positioning plate 11 has two screw holes 7 penetrating in the thickness direction on the left and right (longitudinal) sides.

刻印ピン9はピン位置決め板11のすべての貫通孔に挿入配置する。刻印ピン9は、図5の矢印Aで示すように外力を受けて上下に動き、各刻印ピン9の頭部9aがピン位置決め板11の上面11aから上方へ進出する位置と、ピン位置決め板11の上面11aから退去する位置とをとる。退去した刻印ピン9の下方部分は、ピン位置決め板11の下面11bから下方へ進出する。図5ではグループ内の2つの貫通孔5hそれぞれに刻印ピン9が挿入してあり、図5に向って左の刻印ピン9の頭部9aが上方へ進出し、右の刻印ピン9の頭部が退去している。   The marking pins 9 are inserted and disposed in all through holes of the pin positioning plate 11. The marking pin 9 receives an external force and moves up and down as indicated by an arrow A in FIG. 5, a position where the head 9 a of each marking pin 9 advances upward from the upper surface 11 a of the pin positioning plate 11, and the pin positioning plate 11. And a position for leaving the upper surface 11a. The lower part of the marking pin 9 that has moved out advances downward from the lower surface 11 b of the pin positioning plate 11. In FIG. 5, the marking pin 9 is inserted in each of the two through holes 5h in the group, and the head 9a of the left marking pin 9 advances upward toward FIG. Has left.

(刻印ピンの実施形態)
図3及び図5に示した刻印ピン9は磁石(たとえば、磁性を帯びた鉄)で作られており、強磁性材料のピン位置決め板1,11に磁力によって吸着するので、この吸着によって貫通孔5h内に仮に保持される。刻印ピン9に磁性を帯びさせたのは、主として、ピン位置決め板1,11を基盤31から取り外したときに刻印ピン9が貫通孔5hから落下しないようにするためである。したがって、たとえば、刻印ピン9の落下を不便と感じない場合、刻印ピン9の落下を阻止するための他の手段を講じた場合には、磁性を帯びさせる必要は必ずしもない。
(Embodiment of engraved pin)
The marking pin 9 shown in FIGS. 3 and 5 is made of a magnet (for example, magnetic iron) and is attracted to the pin positioning plates 1 and 11 of ferromagnetic material by magnetic force. Temporarily held within 5h. The reason why the marking pin 9 is magnetized is mainly to prevent the marking pin 9 from dropping from the through hole 5h when the pin positioning plates 1 and 11 are removed from the base 31. Therefore, for example, when it is not inconvenient to drop the marking pin 9 or when other measures for preventing the dropping of the marking pin 9 are taken, it is not always necessary to be magnetized.

図6に示した刻印ピン19は頭部19aと、頭部19aから下方へ延びる第1柱部19bと、第1柱部19bから境界面21を介して下方へ延びる、第1柱部19bより外径の小さな第2柱部19cとからなる。一方、ピン位置決め板1´の貫通孔23は、第1柱部19bが摺動する第1孔部23aと、第1孔部23aから肩25を介して下方へ延びる、第1孔部23aより内径の小さな、第2柱部19cが摺動する第2孔部23bとからなる。刻印ピン19と貫通孔23は機械加工で作る。   The marking pin 19 shown in FIG. 6 includes a head portion 19a, a first column portion 19b extending downward from the head portion 19a, and a first column portion 19b extending downward from the first column portion 19b via the boundary surface 21. It consists of the 2nd pillar part 19c with a small outer diameter. On the other hand, the through hole 23 of the pin positioning plate 1 ′ has a first hole portion 23 a in which the first pillar portion 19 b slides and a first hole portion 23 a that extends downward from the first hole portion 23 a via the shoulder 25. It consists of a second hole portion 23b with a small inner diameter through which the second column portion 19c slides. The marking pin 19 and the through hole 23 are made by machining.

刻印ピン19は境界面21を肩25に載せて仮に保持される。この状態で第2柱部19cの下方部分がピン位置決め板1´の下面1´bから下方へ進出する長さdは、進出した第2柱部の下方部分がスライド板の凸面によって上方へ押し上げられる結果、刻印ピンの頭部19aがピン位置決め板1´の上面1´aから上方へ進出する長さDと等しい。刻印ピン19はピン位置決め板11、すなわちグループに2つの刻印ピンを配置するピン位置決め板11の場合にも適用できる。   The marking pin 19 is temporarily held with the boundary surface 21 placed on the shoulder 25. In this state, the length d at which the lower part of the second column part 19c advances downward from the lower surface 1'b of the pin positioning plate 1 'is pushed upward by the convex surface of the slide plate. As a result, the head 19a of the marking pin is equal to the length D that advances upward from the upper surface 1'a of the pin positioning plate 1 '. The marking pin 19 can also be applied to the pin positioning plate 11, that is, the pin positioning plate 11 in which two marking pins are arranged in a group.

(基盤とスライド板の実施形態)
基盤31がピン位置決め板1の下方に間隔をおいて配置される。図8に示すように、基盤31は19枚の仕切り板33によって20個の区画35に仕切られている。仕切り板33はピン位置決め板1の下面1bと接触する支持部33aと、支持部33aから延びている仕切り部33bを有する。仕切り板33は基盤31を製作する際、金属を鋳造して、又は樹脂を射出成形して基盤31と一体に作ることが好ましい。
(Embodiment of base and slide plate)
The base 31 is disposed below the pin positioning plate 1 with an interval. As shown in FIG. 8, the base 31 is partitioned into 20 partitions 35 by 19 partition plates 33. The partition plate 33 has a support portion 33a that contacts the lower surface 1b of the pin positioning plate 1 and a partition portion 33b that extends from the support portion 33a. When the base plate 31 is manufactured, the partition plate 33 is preferably made integrally with the base plate 31 by casting a metal or injection molding a resin.

スライド板37が基盤31に配置され、支持される。図示の実施形態のように、基盤31が仕切り板33によって定められた区画35を有する場合、スライド板37を区画35内に配置する。各グループの3つのドット位置5(貫通孔5h,刻印ピン9)に対応して一つのスライド板37を配置することから、ピン位置決め板1の各一文字区画3に含まれる2つのグループ5a,5bのために2枚のスライド板37を区画35内に配置する。   A slide plate 37 is disposed on and supported by the base 31. When the base 31 has a partition 35 defined by the partition plate 33 as in the illustrated embodiment, the slide plate 37 is disposed in the partition 35. Since one slide plate 37 is arranged corresponding to the three dot positions 5 (through hole 5h, marking pin 9) of each group, the two groups 5a, 5b included in each one character section 3 of the pin positioning plate 1 are arranged. For this purpose, two slide plates 37 are arranged in the compartment 35.

前述のように、ピン位置決め板11の各一文字区画13に含まれるグループは3つであるから、ピン位置決め板11を使用する場合、区画内に3枚のスライド板を配置する必要がある。換言すると、基盤31に仕切り板を設けて区画を定める場合、ピン位置決め板1用の区画35を備える基盤31はピン位置決め板11を使用する場合には使用できないため、3枚のスライド板が入る区画を備える基盤を別途製作する必要がある。   As described above, since one character section 13 of the pin positioning plate 11 includes three groups, when the pin positioning plate 11 is used, it is necessary to arrange three slide plates in the section. In other words, when a partition plate is provided on the base 31 to determine the section, the base 31 provided with the section 35 for the pin positioning plate 1 cannot be used when the pin positioning plate 11 is used, so that three slide plates are inserted. It is necessary to make a separate base with compartments.

スライド板37は、各グループ内の貫通孔に配置した刻印ピン9の進出を定める同じレベルにある凸面37a,37b,37cと、退去を定める同じレベルにある凹面37d,37eを刻印ピンに対向する上面39に有し、上面39の長さ方向へ移動可能に支持される。すなわち、凸面37a,37b,37cは、何れもピン位置決め板1の下面1bに密着可能な高さに形成してあり、凹面37d,37eはピン位置決め板1の下面1bに対して同じ深さ寸法に形成してある。凹面37dは凸面37aと凸面37bとの間にあり、実質的に、刻印ピン9の3本分と刻印ピン9相互間の間隔の3つ分を加えた長さを有する。また、凹面37eは凸面37dと凸面37cとの間にあり、実質的に、刻印ピン9の1本と前記間隔を加えた長さを有する。なお、刻印ピン19についてもスライド板37による操作は全く同じであるため、次には刻印ピン9について説明する。   The slide plate 37 has convex surfaces 37a, 37b, 37c at the same level that determine the advancement of the marking pin 9 disposed in the through hole in each group, and concave surfaces 37d, 37e at the same level that determine the retreat, facing the marking pin. The upper surface 39 is supported so as to be movable in the length direction of the upper surface 39. That is, the convex surfaces 37 a, 37 b, and 37 c are all formed at a height that can be in close contact with the lower surface 1 b of the pin positioning plate 1, and the concave surfaces 37 d and 37 e have the same depth dimension with respect to the lower surface 1 b of the pin positioning plate 1. Is formed. The concave surface 37d is between the convex surface 37a and the convex surface 37b, and has a length obtained by adding substantially three portions of the marking pins 9 and three intervals between the marking pins 9. The concave surface 37e is between the convex surface 37d and the convex surface 37c, and has a length substantially equal to one of the marking pins 9 plus the interval. In addition, since the operation by the slide plate 37 is the same also about the marking pin 19, the marking pin 9 will be described next.

図7を参照して、スライド板37による刻印ピン9の操作を説明する。スライド板37を矢印B方向で右向きに引っ張ると、3本の刻印ピン9が凸面37aに載る。その結果、3本の刻印ピン9の頭部9aがピン位置決め板1の上面から上方へ進出する(図7(a))。   With reference to FIG. 7, the operation of the marking pin 9 by the slide plate 37 will be described. When the slide plate 37 is pulled rightward in the arrow B direction, the three marking pins 9 are placed on the convex surface 37a. As a result, the heads 9a of the three marking pins 9 advance upward from the upper surface of the pin positioning plate 1 (FIG. 7A).

2本の刻印ピン9を進出位置にするには次の3通りがある。図7(a)を基準にして説明する。図7(a)において、左の刻印ピンと中央の刻印ピンを進出位置にする場合、スライド板37を1ピッチ、つまり刻印ピン9と刻印ピン相互間の間隔を加えた長さ左方へ押し込む。そうすると、右の刻印ピン9が凹面37dに落ちて頭部9aが退去する。左の刻印ピン9と右の刻印ピン9を進出位置にする場合、スライド板37を6ピッチ左方へ押し込む。そうすると、右の刻印ピンが凸面37cに載り、中央の刻印ピンが凹面37eに落ちて頭部9aが退去し、左の刻印ピンが凸面37bに載る。中央の刻印ピン9と右の刻印ピン9を進出位置にする場合、スライド板37を7ピッチ左方へ押し込む。そうすると、右の刻印ピン9と中央の刻印ピン9が凸面37cに載り、左の刻印ピン9が凹面37eに落ちて退去する。換言すると、中央の刻印ピン9は凸面37cによって押し上げられて移動する。この押し上げる力が、刻印ピン9が受ける外力である。刻印ピン9が磁性を帯びている場合には、その吸着力により自重落下しない場合があり得るが、そのときは、上から指や被刻印シートによって押圧すれば退去させることができる。   There are the following three ways to bring the two engraving pins 9 into the advanced position. Description will be made with reference to FIG. In FIG. 7A, when the left marking pin and the center marking pin are set to the advanced positions, the slide plate 37 is pushed to the left by one pitch, that is, the length to which the interval between the marking pin 9 and the marking pin is added. Then, the right marking pin 9 falls on the concave surface 37d and the head portion 9a moves away. When the left marking pin 9 and the right marking pin 9 are set to the advanced positions, the slide plate 37 is pushed to the left by 6 pitches. Then, the right marking pin is placed on the convex surface 37c, the central marking pin falls on the concave surface 37e, the head 9a is retracted, and the left marking pin is placed on the convex surface 37b. When the center marking pin 9 and the right marking pin 9 are set to the advanced positions, the slide plate 37 is pushed to the left by 7 pitches. Then, the right marking pin 9 and the center marking pin 9 are placed on the convex surface 37c, and the left marking pin 9 falls on the concave surface 37e and moves away. In other words, the center marking pin 9 is pushed up by the convex surface 37c and moves. This pushing force is an external force received by the marking pin 9. If the marking pin 9 is magnetized, it may not fall by its own weight due to its attracting force, but in that case, it can be moved away by pressing it with a finger or a stamped sheet from above.

1本の刻印ピン9の頭部9aを進出位置にするには次の3通りがある。左の刻印ピン9を進出位置にする場合、スライド板37を図7(a)の位置から2ピッチ左方へ押し込む。そうすると、図7(b)に示すように右の刻印ピンと中央の刻印ピンが凹面37dに落ちて頭部が退去する。中央の刻印ピン9を進出位置にする場合、スライド板37を図7(a)の位置から5ピッチ左方へ押し込む。そうすると、図7(c)に示すように右の刻印ピン9が凹面37eに落ち、中央の刻印ピン9が凸面37bに載り、左の刻印ピン9が凹面37d上に位置する。右の刻印ピン9を進出位置にする場合、スライド板37を図7(a)の位置から4ピッチ左方へ押し込む。そうすると、右の刻印ピン9が凸面37bに載り、中央の刻印ピン9と左の刻印ピン9が凹面37d上に位置する。   There are the following three ways to bring the head 9a of one marking pin 9 into the advanced position. When the left marking pin 9 is set to the advanced position, the slide plate 37 is pushed to the left by 2 pitches from the position shown in FIG. Then, as shown in FIG. 7B, the right marking pin and the center marking pin fall on the concave surface 37d, and the head moves away. When the center engraving pin 9 is set to the advanced position, the slide plate 37 is pushed to the left by 5 pitches from the position shown in FIG. Then, as shown in FIG. 7C, the right marking pin 9 falls on the concave surface 37e, the central marking pin 9 rests on the convex surface 37b, and the left marking pin 9 is positioned on the concave surface 37d. When the right marking pin 9 is set to the advanced position, the slide plate 37 is pushed to the left by 4 pitches from the position shown in FIG. Then, the right marking pin 9 is placed on the convex surface 37b, and the central marking pin 9 and the left marking pin 9 are positioned on the concave surface 37d.

刻印ピン9が一本も進出しない状態、つまり3本の刻印ピン9を退去位置にするには、スライド板37を図7(a)の位置から3ピッチ押し込み、3本の刻印ピン9を凹面37d上に位置させる。   In a state where none of the marking pins 9 has advanced, that is, to move the three marking pins 9 to the retracted position, the slide plate 37 is pushed in by 3 pitches from the position of FIG. 7A, and the three marking pins 9 are concave. 37d.

ピン位置決め板11を使用する場合のスライド板は、前記スライド板37の凸面及び凹面の配置に準じて形成する。この場合、2本の刻印ピンが進出している場合の1通り、1本の刻印ピンが進出している場合の2通り、2本の刻印ピンが退去している場合の1通りの操作を達成するようにする。   When the pin positioning plate 11 is used, the slide plate is formed according to the arrangement of the convex and concave surfaces of the slide plate 37. In this case, one operation when two engraving pins are advanced, one operation when one engraving pin is advanced, two operations when one engraving pin is advanced, and one operation when two engraving pins are moved out. To achieve.

スライド板37はスライド板の移動方向に等間隔をおいた複数の切欠き41を下面40に有する。切欠き41は2つの傾斜面を有するもので断面が三角形状を呈しており、2つの傾斜面は下面40で最も大きな幅を有し、上方に向けて収斂している。1つの切欠き41と隣接する切欠き41との間の間隔Pはスライド板37の1ピッチと等しい。   The slide plate 37 has a plurality of notches 41 on the lower surface 40 at equal intervals in the moving direction of the slide plate. The notch 41 has two inclined surfaces and has a triangular cross section. The two inclined surfaces have the largest width on the lower surface 40 and converge upward. An interval P between one notch 41 and the adjacent notch 41 is equal to one pitch of the slide plate 37.

基盤31は進出位置で前記切欠き41に嵌まるストッパピン43を備える。ストッパピン43は球体であり、ばね45によって上方の進出位置に向けて偏倚されている。ばね45のばね力は小さいため、スライド板37を移動させる水平力によってストッパピン43を下方へ押し下げることができる。   The base 31 includes a stopper pin 43 that fits into the notch 41 at the advanced position. The stopper pin 43 is a spherical body, and is biased toward the upper advanced position by a spring 45. Since the spring force of the spring 45 is small, the stopper pin 43 can be pushed downward by a horizontal force that moves the slide plate 37.

(Embodiment of lifting mechanism)
A braille marking device 75 shown in FIG. 11 includes a base portion 60 and an elevating mechanism 55 provided on an upper surface on one end side of the base portion 60 as main components, and the base 31 described above on the base portion 60. Etc. are installed. The elevating mechanism 55 includes support bases 57 and 57 which stand on the base portion 60 so as to face each other in the width direction of the base portion 60. The support bases 57, 57 are elevating members 59, 59 for fixing the pressing plate 51 described above, an arm 65 with a handle 63 fixed to pivots 61, 61 rotatably supported by the upper end of the support base 57, and an arm. And means 67 for transmitting the rotation of 65 around the pivot 61 to the elevating material 59.

図11の実施形態では、2つの支持台57のそれぞれに枢軸61を取りつけて各枢軸61にアーム65を固定し、これらアーム65を取っ手63で結合した、いわゆるコ字形タイプである。昇降材59は図示しないばねによって上方へ向けて偏倚されている。アーム65の回転を昇降材59に伝達する手段67は枢軸61に固定したピニオン69と、昇降材59に固定した、ピニオン69とかみ合うラック71とからなる。アーム65を枢軸61を中心として矢印Eのように回転させるとピニオン69が回転する。ピニオン69の回転はラック71を上下動させ、これに伴いラック71に取りつけてある昇降材59が上下運動する。昇降材59の降下は押圧板51を押し下げ、被刻印シートに点字を刻印させる。これとは逆に昇降材59の上昇は押圧板51を上昇させる。   The embodiment of FIG. 11 is a so-called U-shaped type in which a pivot 61 is attached to each of the two support bases 57, an arm 65 is fixed to each pivot 61, and these arms 65 are coupled by a handle 63. The elevating material 59 is biased upward by a spring (not shown). The means 67 for transmitting the rotation of the arm 65 to the lifting / lowering member 59 includes a pinion 69 fixed to the pivot 61 and a rack 71 fixed to the lifting / lowering member 59 and meshing with the pinion 69. When the arm 65 is rotated about the pivot 61 as shown by an arrow E, the pinion 69 is rotated. The rotation of the pinion 69 moves the rack 71 up and down, and accordingly, the elevating material 59 attached to the rack 71 moves up and down. The lowering of the elevating material 59 pushes down the pressing plate 51 and causes the braille to be imprinted on the stamped sheet. On the contrary, the lifting of the elevating material 59 raises the pressing plate 51.

(刻印操作)
図11に示した点字刻印器75を使用して被刻印シートに点字を刻印するには次のようにする。図12及び図13に示すように、一文字区画のグループ毎にスライド板37を移動してピン位置決め板1の所定の刻印ピン9を進出位置又は退去位置にする。例えば、左端にアを刻印する場合、第1の一文字区画81にある2つのスライド板37のうち、左のスライド板37Lを使用して、3つの刻印ピンのうち最も奥にある刻印ピン(図7(a)の左の刻印ピン)を凸面37aと係合させて進出位置におく。また、右のスライド板37Rを使用して3つの刻印ピンを凹面37dに導く。順次、第2の一文字区画82、第3の一文字区画83のように、刻印すべき点字に応じて刻印ピン9の進出及び退去を定める。このとき、ストッパピン43とスライド板37の切欠き41の作用で、スライド板37を所定位置に速やかに導くことができる。
(Engraving operation)
In order to imprint Braille on a sheet to be engraved using the Braille engraving machine 75 shown in FIG. As shown in FIGS. 12 and 13, the slide plate 37 is moved for each group of character sections, and the predetermined marking pin 9 of the pin positioning plate 1 is set to the advanced position or the retracted position. For example, when marking a at the left end, among the two slide plates 37 in the first character block 81, the left slide plate 37L is used, and the most deeply stamped pin (see FIG. 7 (a), the left marking pin) is engaged with the convex surface 37a and placed in the advanced position. Further, the three marking pins are guided to the concave surface 37d using the right slide plate 37R. Sequentially, as in the second one-character section 82 and the third one-character section 83, the advancement and withdrawal of the marking pin 9 are determined according to the braille to be stamped. At this time, the slide plate 37 can be quickly guided to a predetermined position by the action of the notch 41 of the stopper pin 43 and the slide plate 37.

スライド板37による刻印ピン9の設定が完了した後、ピン位置決め板1の上に厚紙などを置き、刻印ピン9の頭部を軽く押える。これは磁力によってピン9が仮に保持されている場合、仮の保持を解消し、不要な頭部が刻印の障害となるのを防ぐためである。刻印ピン19の場合にはこの作業は不要である。   After the setting of the marking pin 9 by the slide plate 37 is completed, a thick paper or the like is placed on the pin positioning plate 1 and the head of the marking pin 9 is lightly pressed. This is because when the pin 9 is temporarily held by the magnetic force, the temporary holding is canceled and an unnecessary head is prevented from becoming an obstacle to the marking. In the case of the marking pin 19, this operation is not necessary.

図14に示すように、ピン位置決め板1の上に被刻印シート85を導く。図示の実施形態では被刻印シート85は名刺の大きさであり、名刺に刻印することができる。断面がL形の位置決め具87を基盤31に取りつけておき、被刻印シート85のエッジを位置決め具87に突き当てたとき、所定の箇所に刻印できるようにすることが好ましい。被刻印シート85を所定位置に配置した後、取っ手63によってアーム65を回転し、押圧板51を押し下げて被刻印シート85に刻印して刻印が完了する。アーム65を逆向きに回転し、被刻印シート85を取り出す。   As shown in FIG. 14, the stamped sheet 85 is guided onto the pin positioning plate 1. In the illustrated embodiment, the stamped sheet 85 has the size of a business card and can be stamped on the business card. It is preferable that a positioning tool 87 having an L-shaped cross section is attached to the base 31 so that when the edge of the stamped sheet 85 is abutted against the positioning tool 87, a predetermined position can be stamped. After the stamped sheet 85 is arranged at a predetermined position, the arm 65 is rotated by the handle 63, the pressing plate 51 is pushed down, and the stamped sheet 85 is stamped to complete the stamping. The arm 65 is rotated in the reverse direction, and the stamped sheet 85 is taken out.
