【考案の詳細な説明】 本案はラベル貼着機等に使用される印字装置に関するも
のである。[Detailed Description of the Invention] The present invention relates to a printing device used in a label pasting machine or the like.

此種印字装置は、エンドレスの印字ベルトを前方受部材
と後方回転盤間に掛渡して、回転盤を回転させる事によ
り受台前面に位置する印字を交替せしめる構成であるが
、上記印字ベルトは印刷に必要な数だけ複数個並列状に
設けられるため、此等印字ベルトをｌ箇の受部材に取掛
けると被印刷面の微小な凹凸によって印刷ムラが生じる
事を避けられない。This type of printing device has an endless printing belt that is stretched between the front receiving member and the rear rotary disk, and by rotating the rotating disk, the printing located on the front of the receiving stand is changed. Since a plurality of belts are provided in parallel in the number necessary for printing, when these printing belts are mounted on one receiving member, it is inevitable that printing unevenness will occur due to minute irregularities on the printing surface.

このため従来の此種装置にあっては、第５図に示す如く
、印字ベルト１を受ける前方受部材を、各印字ベルト毎
に独立して設けられる回転駒２で構成すると共にこの回
転駒２の中央に円孔３を形成し、この円孔３に円孔の口
径より直径が小さい支軸４を挿通して回転駒２を支承す
る一方、回転駒３の背後には弾性押圧手段５を設けて回
転駒３を印字ベルト１の内側に押漬する様構成している
。For this reason, in the conventional device of this kind, as shown in FIG. A circular hole 3 is formed in the center of the rotary piece 3, and a spindle 4 having a smaller diameter than the diameter of the circular hole is inserted into the circular hole 3 to support the rotary piece 2, while an elastic pressing means 5 is provided behind the rotary piece 3. The rotary piece 3 is provided so as to be pushed into the inside of the printing belt 1.

この様な構成によれば、支軸４が押圧手段５側の孔壁に
当接して回転駒２を支承するから、回転駒２は孔内の空
隙幅Ｗだけ押圧手段側に後退する事が出来、従って印字
ベルト群全体からみれば、被印刷面６の凹凸を吸収して
鮮明な印刷を施す事が出来る効果がある。According to such a configuration, since the support shaft 4 supports the rotary piece 2 by contacting the hole wall on the side of the pressing means 5, the rotary piece 2 is prevented from retreating toward the pressing means side by the gap width W in the hole. Therefore, from the perspective of the printing belt group as a whole, the unevenness of the printing surface 6 can be absorbed and clear printing can be performed.

しかしながら、この様な従来の構成においては、印字を
交替さすために印字ベルト１を回避せしめると、回転駒
２が印字ベルト１に引張られて微小ではあるが矢印ａ方
向に位置ズレを生じ、これによって印刷ズレが発生する
と言う欠点があった。However, in such a conventional configuration, when the printing belt 1 is avoided in order to change printing, the rotary piece 2 is pulled by the printing belt 1, causing a slight positional shift in the direction of the arrow a. There was a drawback that printing misalignment occurred due to this.

而してこの回転駒２の位置ズレは円孔３の直径が大きく
なるのに比例して大きくなるから、円孔３の口径を大き
くする事が出来ず、このため回転駒２の後退可能距離も
小さくなって被印刷面６の凹凸を充分吸収出来ない事も
あると言う欠点があった。Since the positional deviation of the rotary piece 2 increases in proportion to the diameter of the circular hole 3, it is not possible to increase the diameter of the circular hole 3, and for this reason, the retractable distance of the rotary piece 2 increases. There is also a drawback that the unevenness of the printing surface 6 may not be sufficiently absorbed due to the small size.

本案はこの様な欠点のない印字装置を提供するものであ
る。The present invention provides a printing device that does not have such drawbacks.

以下本案印字装置を第１図乃至第４図につき説明すると
、本案装置は所要数並設された印字ベルト７を、各印字
ベルト毎に設けられた回転駒８と回転盤９間とに取掛け
て、回転盤９を回転せしめる事により回転駒８の前面に
ある印字１０′を交替せしめる構成である事従来の装置
と同様である。The printing device according to the present invention will be explained below with reference to FIGS. 1 to 4. The printing device according to the present invention has a required number of printing belts 7 arranged in parallel, and is mounted between a rotary piece 8 and a rotary disk 9 provided for each printing belt. This is similar to the conventional apparatus in that the printing 10' on the front surface of the rotary piece 8 is changed by rotating the rotary disk 9.

上記印字ベルト７の内面には各印字１０，１０毎に係止
突起１１が設けてあり、この係止突起１１は回転駒８の
外周に凹設された係合溝１２と回転盤９の外周に凹設さ
れた保合溝１３とに係着されていて、回転盤９を回転さ
せた時に回転駒８が連動回転せしめられる様構成されて
いる。A locking protrusion 11 is provided on the inner surface of the printing belt 7 for each print 10, 10, and the locking protrusion 11 is connected to an engaging groove 12 recessed in the outer circumference of the rotary piece 8 and the outer circumference of the rotary disk 9. The rotary piece 8 is engaged with a retaining groove 13 recessed in the rotary plate 9, so that the rotary piece 8 is rotated in conjunction with the rotary plate 9 when the rotary disk 9 is rotated.

上記回転駒８は、軸直角断面が偶数の角部を有する正多
角形、例へば正四角形に作られていて、これにより回転
周面に４箇の受面１４，１４を形成すると共に中央には
軸孔１５を透設して構成されており、更に上記軸孔１５
は回転駒８と同角数の正多角形状に形成されると共にそ
の各角部１５′が夫々上記受面１４の中心線り上にある
様位置せしめられている。The rotary piece 8 has a cross section perpendicular to its axis that is formed into a regular polygon, for example, a regular quadrilateral, with an even number of corners, and thereby forms four receiving surfaces 14, 14 on the rotating circumferential surface, and at the center. The shaft hole 15 is transparent, and the shaft hole 15 is transparent.
is formed in the shape of a regular polygon having the same number of angles as the rotary piece 8, and is positioned so that each corner 15' is on the center line of the receiving surface 14, respectively.

上記軸孔１５には支軸１６が遊挿されており、この支軸
１６はその直径を軸孔１５の孔径ｄより小さく選らばれ
ている。A support shaft 16 is loosely inserted into the shaft hole 15, and the diameter of the support shaft 16 is selected to be smaller than the hole diameter d of the shaft hole 15.

上記支軸１６は支枠１７に固定されており、この支枠１
７には上記回転盤９も支承されている。The support shaft 16 is fixed to a support frame 17, and this support frame 1
7 also supports the rotary disk 9.

上記支枠１７には弾性押圧手段が設けられており、この
押圧手段により回転駒８は支軸１６で前進を阻止される
迄印字ベルト７に押漬され、この押漬力によって印字ベ
ルト７は緊張せしめられている。The supporting frame 17 is provided with elastic pressing means, and this pressing means presses the rotary piece 8 against the printing belt 7 until it is prevented from advancing by the supporting shaft 16, and the printing belt 7 is pushed by this pressing force. I feel nervous.

上記押圧手段は、例へば支枠１７に横架された支片１８
と、この支片１８により支承されて回転駒８の背面に接
離する方向へ摺動可能ならしめられた摺動杆１９と、こ
の摺動杆１９を常時回転駒８に押圧する発条２０とを備
えており、この発条２０によって回転駒８を印字ベルト
７に向は附勢する様構成されている。The above-mentioned pressing means is, for example, a support piece 18 horizontally suspended on the support frame 17.
A sliding rod 19 supported by this support piece 18 and capable of sliding toward and away from the back surface of the rotating piece 8, and a spring 20 that constantly presses this sliding rod 19 against the rotating piece 8. The rotary piece 8 is urged toward the printing belt 7 by the spring 20.

以上の処において軸孔１５の角部１５′は、第４図Ａに
示す如く曲面で形成しても良く、又角部１５′間の孔壁
も第４図Ｂの如く膨出面に形成しても良い。In the above, the corners 15' of the shaft hole 15 may be formed as curved surfaces as shown in FIG. 4A, and the hole walls between the corners 15' may also be formed as bulged surfaces as shown in FIG. 4B. It's okay.

此等の形状は軸孔１５の効果を失わない限り所望に選定
すれば良い。These shapes may be selected as desired as long as the effect of the shaft hole 15 is not lost.

本案装置はこの様なものであるから、被印刷面６に凸部
があれば、これによって回転駒８が発条２０に抗して後
退し、印字ベルト群全体としては被印刷面６の凹凸を吸
収して印刷を施せるものであるが、本装置は、前述の如
く、回転駒８の軸孔１５が印字１０′を受けている受面
１４′の中心線上に角部１５′を設けであるため、下記
効果を期待する事が出来る。Since the present device is as described above, if there is a convex part on the printing surface 6, the rotary piece 8 will move backward against the spring 20, and the printing belt group as a whole will be able to absorb the unevenness of the printing surface 6. As described above, this device is provided with a corner 15' on the center line of the receiving surface 14' where the shaft hole 15 of the rotary piece 8 receives the print 10'. Therefore, the following effects can be expected.

支軸１６が角部１５′に嵌合して、角部１５′の奥狭な
空間において壁面間で挟止されるから、静止時の回転駒
８を常に所定の位置に定置せしめる事が出来、このため
印字ベルト７の回避によって回転駒前面にある印字１０
′の位置がズレると言う従前欠点を一掃出来る。Since the support shaft 16 fits into the corner 15' and is clamped between the walls in the narrow space of the corner 15', the rotary piece 8 can always be fixed at a predetermined position when it is stationary. , Therefore, by avoiding the printing belt 7, the printing 10 on the front of the rotating piece is
The previous drawback that the position of ′ is misaligned can be wiped out.

回転駒８の矢印ａ方向への位置ズレを角部１５′で防止
出来るため、軸孔１５の口径を大きくして空隙幅Ｗを増
大させ、以って回転駒８の後退可能距離を長く出来るか
ら、被印刷面６に大きな凸部があってもこれを回転駒８
の後退で吸収出来、従ってかかる場合にも鮮明な印刷を
行う事が出来る他、印字ベルト７の肉厚に異同があって
もこれを充分吸収出来るから、印字ベルト製造が容易と
なり、安価な印字ベルトを使用出来る。Since the corner portion 15' prevents the rotation piece 8 from shifting in the direction of the arrow a, the diameter of the shaft hole 15 is increased to increase the gap width W, thereby increasing the distance over which the rotation piece 8 can retreat. Therefore, even if there is a large protrusion on the printing surface 6, it can be removed by the rotation piece 8.
Therefore, clear printing can be performed even in such a case, and even if there are differences in the thickness of the printing belt 7, this can be sufficiently absorbed, making it easy to manufacture the printing belt and resulting in inexpensive printing. You can use a belt.
