- the present invention relates to a tape dispenser used when applying a tape to an object to be applied.
- a tape dispenser is an instrument that holds a reel around which the tape is wound, and after the tape drawn out from the reel is bonded to an object to be applied by pressure, and then cuts between the tape application site and the reel with a cutter blade.
- the tape pulled out from the reel may be loosened and may not hit the cutter blade, or the tape may be distorted and not cut cleanly while the cutter blade cuts the tape.
- the tape contains a material that is difficult to cut, such as cellulose (paper) fibers
- the tape does not hit the cutting edge firmly, so it takes a lot of time to cut the tape and the usability is very poor.
- the present invention is intended to provide a tape dispenser that can reliably and easily perform a work of cutting a tape after the tape is applied to an object to be applied.
- the present invention provides a tape dispenser used when a tape is applied to an object to be applied, the main body holding a reel around which the tape is wound, and a tape drawn from the reel.

- a tape dispenser having a clamping mechanism that is displaced relative to the cutter blade is configured.
- the clamping mechanism has a pair of clamping members that clamp the tape from both the front and back sides, and in the process where one clamping member approaches the other clamping member, the clamping mechanism displaces in conjunction with the clamping member. It is preferable that the pressing member to be applied applies a tension to the tape that strikes the cutter blade by pressing between the tape application site and the reel.
- the main body has a case gripped by the user and a drive body that is displaceable relative to the case and has a tip projecting from the case, and affixing the tape application part to the object to be applied

It is not necessary to make contact, and damage to the object to be stuck by the cutter blade can be avoided. Further, since the cutter blade is shielded by the outer edge of the tip of the drive body, the possibility that the cutter blade touches the user's finger is reduced, and the safety is further enhanced.
- a pressure-bonding member that protrudes from the outer edge of the tip of the main body in order to crimp the tape drawn from the reel to the object to be pasted, and retracts so as to be immersed more than the outer edge when cutting the tape against the cutter blade. If provided, the tape can be firmly and strongly applied to the cutting edge of the cutter blade through the retraction of the pressure roller, and the tape can be cut reliably.

- Retraction of the roller 324 so as to be immersed more than the outer edge of the cutter housing 313 leads to loosening the tape 42 wound around the roller 324, but the holding member 322 is moved closer to the first case member 21.
- the trajectory of the tape 42 between the roller 324 and the reel 41 is bent and tension is applied to the tape 42, so that the tape 42 to be applied to the cutting edge of the cutter blade 314 is prevented from being loosened.

Therefore, the tape 42 can be strongly applied to the cutting edge of the cutter blade 314 without being loosened or distorted while the tape 42 is in tension, and the tape 42 is cut surely and beautifully.
- the protrusion 322c of the movable holding member 322 extends from the portion 311f extending along the Z-axis direction in the long hole 311e to the X axis. It changes to the part 311g which expands along a direction.
- the movable clamping member 322 is displaced along the X-axis direction from the first case member 21 side toward the second case member 22 side. That is, the substrate portion 322a of the movable holding member 322 is separated from the substrate portion 323a of the fixed holding member 323 so that the holding of the tape 42 is eliminated and the holding member 322 does not press the tape 42.

Description
本発明は、貼付対象物にテープを貼付する際に用いられるテープディスペンサに関する。
The present invention relates to a tape dispenser used when applying a tape to an object to be applied.
紙の書類や書籍のページ等の貼付対象物にテープを貼付する目的で使用されるテープディスペンサが周知である(例えば、下記特許文献を参照)。テープディスペンサは、テープが巻き回されたリールを保持し、リールから繰り出したテープを貼付対象物に圧着させて貼付した後、そのテープの貼付部位とリールとの間をカッター刃を以て断ち切る器具である。
2. Description of the Related Art Tape dispensers used for the purpose of sticking tape to sticking objects such as paper documents and book pages are well known (see, for example, the following patent document). A tape dispenser is an instrument that holds a reel around which the tape is wound, and after the tape drawn out from the reel is bonded to an object to be applied by pressure, and then cuts between the tape application site and the reel with a cutter blade. .
従来のテープディスペンサでは、テープを切断しようとする際に、カッター刃の刃先に当たるテープを緊張状態に保つ機構は実装されていない。単にカッター刃がテープに向かって変位する、または使用者がテープをカッター刃に当てるように操作するのみであって、いわば、テープがカッター刃によって裁断されるのを成り行きに任せている。
In the conventional tape dispenser, when trying to cut the tape, a mechanism that keeps the tape that hits the edge of the cutter blade in a tension state is not implemented. The cutter blade is simply displaced toward the tape, or the user only operates to apply the tape to the cutter blade, so to speak, the tape is cut by the cutter blade.
このため、リールから引き出されたテープが弛んでカッター刃に上手く当たらなかったり、カッター刃がテープを裁断する最中にテープが歪んでしまい綺麗に切れなかったりすることが起こり得る。とりわけ、テープが切断しにくい素材、例えばセルロース(紙)繊維等を含有している場合には、テープが刃先にしっかりと当たらないことでテープの切断に多大な手間がかかり、使い勝手が非常に悪くなる。
For this reason, the tape pulled out from the reel may be loosened and may not hit the cutter blade, or the tape may be distorted and not cut cleanly while the cutter blade cuts the tape. In particular, when the tape contains a material that is difficult to cut, such as cellulose (paper) fibers, the tape does not hit the cutting edge firmly, so it takes a lot of time to cut the tape and the usability is very poor. Become.
本発明は、テープを貼付対象物に貼付した後、テープを切断する作業を確実かつ簡便に行い得るテープディスペンサを提供しようとするものである。
The present invention is intended to provide a tape dispenser that can reliably and easily perform a work of cutting a tape after the tape is applied to an object to be applied.
上述した課題を解決するべく、本発明では、貼付対象物にテープを貼付する際に用いられるテープディスペンサであって、テープが巻き回されたリールを保持する本体と、リールから引き出されたテープを切断するためのカッター刃と、リールから引き出されたテープをカッター刃に当てて切断するときに、テープにおける貼付対象物に貼付された貼付部位とリールとの間に介在する中間部位を挟持した状態でカッター刃に対して相対的に変位する挟持機構とを具備するテープディスペンサを構成した。
In order to solve the above-described problems, the present invention provides a tape dispenser used when a tape is applied to an object to be applied, the main body holding a reel around which the tape is wound, and a tape drawn from the reel. When the cutter blade for cutting and the tape drawn from the reel are cut against the cutter blade, the intermediate portion interposed between the affixed portion attached to the object to be attached on the tape and the reel is sandwiched Thus, a tape dispenser having a clamping mechanism that is displaced relative to the cutter blade is configured.
加えて、前記挟持機構が、テープを表裏両面側から挟む一対の挟持部材を有しており、一方の挟持部材が他方の挟持部材に対して接近する過程で、当該挟持部材と連動して変位する押圧部材がテープの貼付部位とリールとの間を押圧することで前記カッター刃に当たるテープに張力を付与するものとすることが好適である。
In addition, the clamping mechanism has a pair of clamping members that clamp the tape from both the front and back sides, and in the process where one clamping member approaches the other clamping member, the clamping mechanism displaces in conjunction with the clamping member. It is preferable that the pressing member to be applied applies a tension to the tape that strikes the cutter blade by pressing between the tape application site and the reel.
前記本体が、使用者が把持するケースと、ケースに対して相対的に変位可能でありその先端部がケースから突出する駆動体とを有しており、テープの貼付部位を貼付対象物に貼付した後に使用者がケースを移動させる操作に起因して貼付対象物側から駆動体の先端部に加わる、駆動体をケース内に押し込もうとする操作力を、テープの中間部位を挟持した前記挟持機構を前記カッター刃に対して相対的に変位させる力に変換する操作力変換機構を具備するものとすれば、ケースの操作(例えば、ケースをを貼付対象物が載置された机の天板等に押し付けるような操作)を通じてテープを切断することが可能となり、簡便である。
The main body has a case gripped by the user and a drive body that is displaceable relative to the case and has a tip projecting from the case, and affixing the tape application part to the object to be applied The operation force applied to the tip of the drive body from the pasting object side due to the operation of the user moving the case after the operation force to push the drive body into the case is sandwiched between the intermediate portions of the tape If an operation force conversion mechanism that converts the clamping mechanism into a force that displaces relative to the cutter blade is provided, the operation of the case (for example, the top of the desk on which the object to be pasted is placed) is operated. It is possible to cut the tape through an operation such as pressing on a plate or the like, which is convenient.
具体的には、前記駆動体が、前記カッター刃を支持する主フレームと、前記挟持機構を支持する副フレームとを有しており、前記操作力によって主フレームが前記ケースに対して変位する変位量よりも副フレームがケースに対して変位する変位量の方が大きくなるように、主フレーム、副フレーム及びケースを連結するリンク部材を設けることで、前記操作力変換機構を構成することが一例である。
Specifically, the drive body has a main frame that supports the cutter blade and a sub-frame that supports the clamping mechanism, and the main frame is displaced with respect to the case by the operation force. An example of configuring the operating force conversion mechanism is to provide a link member that connects the main frame, the sub-frame, and the case so that the amount of displacement of the sub-frame relative to the case is larger than the amount. It is.
前記カッター刃を前記駆動体の先端部に支持させており、そのカッター刃が駆動体の先端部の外縁よりも没入した位置にあるならば、カッター刃の刃先を紙等の貼付対象物に直接接触させずに済み、カッター刃による貼付対象物の損傷を回避できる。また、カッター刃が駆動体の先端部の外縁によって遮蔽されることから、カッター刃が使用者の手指に触れる可能性も低減し、安全性がより一層高まる。
If the cutter blade is supported by the tip of the driving body and the cutter blade is in a position that is more deeply immersed than the outer edge of the tip of the driving body, the cutting edge of the cutter blade is directly applied to the pasting object such as paper. It is not necessary to make contact, and damage to the object to be stuck by the cutter blade can be avoided. Further, since the cutter blade is shielded by the outer edge of the tip of the drive body, the possibility that the cutter blade touches the user's finger is reduced, and the safety is further enhanced.
リールから引き出されたテープを貼付対象物に圧着させるために前記本体の先端部の外縁から突出するとともに、テープをカッター刃に当てて切断するときには当該外縁よりも没入するように退避する圧着部材を具備するものとすれば、圧着ローラの退避を通じてテープをカッター刃の刃先にしっかりと強く当てることが可能となり、確実にテープを切断できるようになる。
A pressure-bonding member that protrudes from the outer edge of the tip of the main body in order to crimp the tape drawn from the reel to the object to be pasted, and retracts so as to be immersed more than the outer edge when cutting the tape against the cutter blade. If provided, the tape can be firmly and strongly applied to the cutting edge of the cutter blade through the retraction of the pressure roller, and the tape can be cut reliably.
リールから引き出されたテープを貼付対象物に圧着させるために前記本体の先端部の外縁から突出するとともに、テープをカッター刃に当てて切断するときには当該外縁よりも没入するように退避する圧着部材は、前記副フレームに支持させることが考えられる。
A pressure-bonding member that protrudes from the outer edge of the tip of the main body in order to crimp the tape drawn from the reel to the object to be pasted, and retracts so as to be immersed more than the outer edge when the tape is cut against the cutter blade. It is conceivable to support the sub-frame.
本発明によれば、テープを切断する作業を確実かつ簡便に行い得るテープディスペンサが実現される。
According to the present invention, a tape dispenser capable of reliably and simply performing the work of cutting the tape is realized.
本発明の一実施形態を、図面を参照して説明する。図1ないし図11に示す本実施形態のテープディスペンサは、本体1が保持しているリール41からテープ42を繰り出し、その繰り出されたテープ42を貼付対象物に貼付した後、テープ42の(貼付対象物に貼付された)貼付部分の終端近傍の箇所をカッター刃314によって切断するものである。
An embodiment of the present invention will be described with reference to the drawings. The tape dispenser of the present embodiment shown in FIGS. 1 to 11 feeds the tape 42 from the reel 41 held by the main body 1, sticks the fed tape 42 to the object to be pasted, A portion near the end of the pasted portion (attached to the object) is cut by the cutter blade 314.
テープ42は、片面即ち裏面に粘着剤または接着剤が予め塗布されており、その粘着剤または接着剤により貼付対象物である紙の書類や書籍のページ等に貼付される。テープ42の色彩は、単色(特に、蛍光色)としてもよいし、模様や図柄等を付したものとしてもよい。テープ42の素材は、セロハンテープ、紙テープ、マスキングテープ、樹脂テープ等、種々考えられるが、本実施形態では、セルロース繊維(特に、和紙)が用いられたテープ42を想定している。テープ42を紙の貼付対象物に貼付したとき、貼付対象物に記載または印刷されている文字等が、テープ42に被覆されながらも当該テープ42を介して透けて見える。故に、本実施形態のテープディスペンサは、ちょうどマーカペンや蛍光ペンのように使用することができる。テープ42(に塗布する粘着剤または接着剤)を、必要に応じて貼付対象物から剥離可能なものとすることも好ましい。
The tape 42 is preliminarily coated with a pressure-sensitive adhesive or adhesive on one side, that is, the back surface, and is affixed to a paper document, a book page, or the like, which is an object to be pasted, with the pressure-sensitive adhesive or adhesive. The color of the tape 42 may be a single color (especially a fluorescent color) or may be provided with a pattern or a pattern. Various materials such as a cellophane tape, a paper tape, a masking tape, and a resin tape can be considered as the material of the tape 42. In this embodiment, a tape 42 using cellulose fibers (particularly Japanese paper) is assumed. When the tape 42 is affixed to a paper affixing object, characters or the like written or printed on the affixing object can be seen through the tape 42 while being covered with the tape 42. Therefore, the tape dispenser of this embodiment can be used just like a marker pen or a fluorescent pen. It is also preferable that the tape 42 (adhesive or adhesive applied to the tape 42) be peelable from the object to be pasted as necessary.
以下、説明の簡明化のため、テープ42が巻き回されたリール41の回転軸と平行な方向をX軸方向、本体1の長手方向(後述する主フレーム31及び副フレーム32の変位方向)をZ軸方向、並びに、これらX軸及びZ軸の双方と直交する方向をY軸方向と定義する。
Hereinafter, for the sake of simplicity, the direction parallel to the rotation axis of the reel 41 around which the tape 42 is wound is the X-axis direction, and the longitudinal direction of the main body 1 (the displacement direction of the main frame 31 and the sub frame 32 described later). The Z-axis direction and the direction orthogonal to both the X-axis and the Z-axis are defined as the Y-axis direction.
本テープディスペンサの本体1は、使用者が把持するケース2と、ケース2に対して相対的に変位可能な駆動体3とを備える。ケース2は、その内部空間に駆動体3及びリール41を収容する、Z軸方向に沿って伸長した容器である。図1に示すように、ケース2は透明であり、外側から見て駆動体3やリール41が透けて見える。ケース2は半割構造をなし、その一方である第一ケース部材21と他方である第二ケース部材22とがX軸方向に沿って対向している。テープ42の補充即ちリール41の交換を行う際には、リール41に臨む第二ケース部材22を第一ケース部材21から脱離させることで、ケース2の内部空間を開放する。
The main body 1 of the tape dispenser includes a case 2 held by a user and a drive body 3 that can be displaced relative to the case 2. The case 2 is a container that extends in the Z-axis direction and accommodates the driving body 3 and the reel 41 in its internal space. As shown in FIG. 1, the case 2 is transparent, and the driver 3 and the reel 41 can be seen through from the outside. The case 2 has a halved structure, and the first case member 21 as one side and the second case member 22 as the other side face each other along the X-axis direction. When the tape 42 is replenished, that is, the reel 41 is replaced, the internal space of the case 2 is opened by detaching the second case member 22 facing the reel 41 from the first case member 21.
駆動体3は、リール41及びテープ42を支持する支持体でもある。駆動体3は、ケース2に対しZ軸方向に沿ってスライドする主フレーム31と、主フレーム31の内にあって主フレーム31に対しスライドする副フレーム32とを要素とし、その双方がケース2に対しZ軸方向に沿って相対的に変位することが可能である。
The driving body 3 is also a support body that supports the reel 41 and the tape 42. The driving body 3 includes a main frame 31 that slides along the Z-axis direction with respect to the case 2 and a sub-frame 32 that slides with respect to the main frame 31 in the main frame 31, and both of them are the case 2. However, it can be relatively displaced along the Z-axis direction.
主フレーム31は、X軸方向に沿って第一ケース部材21側にある主フレームベース311と、X軸方向に沿って第二ケース部材22側にあるカバー312と、Z軸方向に沿った先端(または、下端)側にあるカッターハウジング313とを備える。
The main frame 31 includes a main frame base 311 on the first case member 21 side along the X-axis direction, a cover 312 on the second case member 22 side along the X-axis direction, and a tip along the Z-axis direction. A cutter housing 313 on the (or lower end) side.
主フレームベース311は、X軸方向を向く頂壁311aと、Y軸方向を向くとともに互いに平行に並立し各々が頂壁311aの両側縁にそれぞれ連接した一対の側壁311bとを有している。図4に示すように、頂壁311aの外面には、X軸方向に突出しかつZ軸方向に沿って延伸した凸条311cを設けている。この凸条311cは、図5に示すように、頂壁311aの外面が対向する第一ケース部材21の内面に形成した、Z軸方向に沿って延伸するガイド211内に挿入される。また、各側壁311bの外面に、Z軸方向に延伸する凹溝311dを形成してある。この凹溝311dには、側壁311bの外面が対向する第一ケース部材21の内面に設けた、Y軸方向に突出する突片212が挿入される。主フレーム31がケース2に対してスライドするとき、頂壁311aの凸条311cが第一ケース部材21のガイド211に沿って摺動し、並びに、第一ケース部材21の突片212が側壁311bの凹溝311dに沿って摺動する。
The main frame base 311 has a top wall 311a facing the X-axis direction and a pair of side walls 311b facing the Y-axis direction and juxtaposed in parallel with each other and respectively connected to both side edges of the top wall 311a. As shown in FIG. 4, the outer surface of the top wall 311a is provided with a ridge 311c protruding in the X-axis direction and extending along the Z-axis direction. As shown in FIG. 5, the ridge 311c is inserted into a guide 211 formed on the inner surface of the first case member 21 facing the outer surface of the top wall 311a and extending along the Z-axis direction. Further, a concave groove 311d extending in the Z-axis direction is formed on the outer surface of each side wall 311b. A protrusion 212 protruding in the Y-axis direction provided on the inner surface of the first case member 21 facing the outer surface of the side wall 311b is inserted into the concave groove 311d. When the main frame 31 slides with respect to the case 2, the protrusion 311 c of the top wall 311 a slides along the guide 211 of the first case member 21, and the protruding piece 212 of the first case member 21 has the side wall 311 b. It slides along the concave groove 311d.
主フレームベース311の一方の側壁311bには、凹溝311d以外に、当該側壁311bをY軸方向に沿って貫通した長孔311eを穿っている。長孔311eは、当該側壁311bをY軸方向に沿って見たときに、略L字型をなしている。即ち、長孔311eには、Z軸方向に沿って延伸する部分311fと、X軸方向に沿って拡張する部分311gと、両部分311f、311gをなだらかに接続する湾曲した部分311hとが含まれる。そして、Z軸方向に沿って延伸する部分311fの先端側の端部と、X軸方向に沿って拡張する部分311gの第一ケース部材21側の端部とが、湾曲部分311hを介して連通している。この長孔311eは、後述する挟持機構の動作を惹起するために機能する。
In addition to the groove 311d, a long hole 311e that penetrates the side wall 311b along the Y-axis direction is formed in one side wall 311b of the main frame base 311. The long hole 311e is substantially L-shaped when the side wall 311b is viewed along the Y-axis direction. That is, the long hole 311e includes a portion 311f extending along the Z-axis direction, a portion 311g extending along the X-axis direction, and a curved portion 311h that gently connects the portions 311f and 311g. . The end portion on the tip side of the portion 311f extending along the Z-axis direction and the end portion on the first case member 21 side of the portion 311g extending along the X-axis direction communicate with each other via the curved portion 311h. is doing. The long hole 311e functions to cause an operation of a clamping mechanism described later.
主フレームベース311のZ軸方向に沿った中間部位において、頂壁311aの内面には、X軸方向に突出するストッパ311iを設けてある。このストッパ311iは、主フレーム31に対する副フレーム32のZ軸方向に沿ったスライド移動の範囲を規制するために存在する。また、ストッパ311iの下向面、即ちZ軸方向に沿った先端側を向く面に、スプリングリテーナ311jを設けている。
A stopper 311i protruding in the X-axis direction is provided on the inner surface of the top wall 311a at an intermediate portion along the Z-axis direction of the main frame base 311. The stopper 311 i exists to restrict the range of sliding movement along the Z-axis direction of the sub frame 32 relative to the main frame 31. In addition, a spring retainer 311j is provided on the downward surface of the stopper 311i, that is, the surface facing the tip side along the Z-axis direction.
主フレームベース311のZ軸方向に沿った先端側には、カッターハウジング313を取り付ける。翻って、主フレームベース311の反先端(または、上端)側、頂壁311aの内面には、X軸方向に突出する支軸311kを設ける。支軸311kは、後述するリンク部材34を回動可能に支持し、リンク部材34の回転中心となる。
A cutter housing 313 is attached to the front end side of the main frame base 311 along the Z-axis direction. In turn, a support shaft 311k protruding in the X-axis direction is provided on the opposite end (or upper end) side of the main frame base 311 and on the inner surface of the top wall 311a. The support shaft 311k supports a link member 34, which will be described later, in a rotatable manner, and serves as a rotation center of the link member 34.
カバー312は、主フレームベース311に組み付けられることで、主フレームベース311の頂壁311a及び側壁311bに包囲された内部を部分的に遮蔽するとともに、主フレーム31の内部に収容される副フレーム32の主フレーム31からの離脱を阻止し、かつ支軸311kに支持させたリンク部材34の支軸311kからの抜出を阻止する。
The cover 312 is assembled to the main frame base 311, thereby partially shielding the interior surrounded by the top wall 311 a and the side wall 311 b of the main frame base 311, and the sub frame 32 accommodated in the main frame 31. Is prevented from being detached from the main frame 31 and the link member 34 supported by the support shaft 311k is prevented from being pulled out from the support shaft 311k.
本テープディスペンサにあっては、カバー312が、テープ42を多重に巻き回してなるリール41を直接に支持する。具体的には、X軸方向を向き第二ケース部材22に対向するカバー312の外面に、X軸方向に突出するボス312a及びカラー軸312bをそれぞれ設けている。ボス312aは、リール41を回動可能に支持して、リール41の回転中心となる。
In this tape dispenser, the cover 312 directly supports the reel 41 formed by winding the tape 42 in multiple layers. Specifically, a boss 312a and a collar shaft 312b projecting in the X-axis direction are provided on the outer surface of the cover 312 facing the second case member 22 facing the X-axis direction. The boss 312a supports the reel 41 so as to be rotatable, and serves as a rotation center of the reel 41.
カラー軸312bは、リール41から繰り出されるテープ42を案内する部材であるカラー312cを支持する。本実施形態では、リール41から引き出したテープ42を、その表裏面がともにX軸方向を向くように、テープ42の引出方向即ちリール41の径方向に沿った軸回りに90°捻った上で本体1の先端部まで導く、いわゆる「横引き」方式を採用している。カラー312cは、リール41から引き出されたテープ42における、90°捻られる箇所よりもリール41寄りに位置してテープ42の表面に接触する。このカラー312cにより、テープ42を捻った状態を保ちながら、リール41からテープ42が円滑に引き出されるようにしている。
The collar shaft 312b supports a collar 312c that is a member for guiding the tape 42 fed out from the reel 41. In this embodiment, the tape 42 pulled out from the reel 41 is twisted by 90 ° around the axis along the drawing direction of the tape 42, that is, along the radial direction of the reel 41 so that both the front and back faces in the X-axis direction. A so-called “lateral pulling” method is adopted that leads to the tip of the main body 1. The collar 312 c is located closer to the reel 41 than the portion twisted by 90 ° in the tape 42 pulled out from the reel 41 and contacts the surface of the tape 42. By this collar 312c, the tape 42 is smoothly pulled out from the reel 41 while keeping the twisted state of the tape 42.
カッターハウジング313は、駆動体3の先端部ひいては本体1の先端部の外形を構成する部材である。カッターハウジング313は、ケース2と同様に透明である。カッターハウジング313は、X軸方向を向く頂壁313aと、Y軸方向を向くとともに互いに平行に並立し各々が頂壁313aの両側縁にそれぞれ連接した一対の側壁313bとを有している。主フレームベース311の先端側にカッターハウジング313を取り付けたとき、カッターハウジング313の頂壁313aと主フレームベース311の頂壁311aとが連続し、並びに、カッターハウジング313の側壁313bと主フレームベース311の側壁311bとが略面一となる。そして、カッターハウジング313の頂壁313a及び側壁313bに包囲された内部が、主フレームベース311の頂壁311a及び側壁311bに包囲された内部に連通する。
The cutter housing 313 is a member that constitutes the outer shape of the distal end portion of the driving body 3 and thus the distal end portion of the main body 1. The cutter housing 313 is transparent like the case 2. The cutter housing 313 has a top wall 313a facing the X-axis direction and a pair of side walls 313b facing the Y-axis direction and juxtaposed in parallel with each other and respectively connected to both side edges of the top wall 313a. When the cutter housing 313 is attached to the front end side of the main frame base 311, the top wall 313a of the cutter housing 313 and the top wall 311a of the main frame base 311 are continuous, and the side wall 313b of the cutter housing 313 and the main frame base 311 The side wall 311b is substantially flush. The inside of the cutter housing 313 surrounded by the top wall 313a and the side wall 313b communicates with the inside of the main frame base 311 surrounded by the top wall 311a and the side wall 311b.
図2に示すように、カッターハウジング313の頂壁313aには、テープ42の貼付時及び切断時にテープを視認することのできる貫通窓313cを形成してある。
As shown in FIG. 2, the top wall 313a of the cutter housing 313 is formed with a through window 313c through which the tape can be visually recognized when the tape 42 is applied and cut.
カッターハウジング313の外縁即ち駆動体3(及び、本体1)の外縁は、カッターハウジング313の頂壁313aの下端縁と、これに連なる一対の側壁313bの下端縁及び(第二ケース部材22側の)後端縁とによって形作られる。Y軸方向から見て、側壁313bの下端縁は、頂壁313aの下端縁に連なる部位では頂壁313aの下端縁と同一平面上にあるようなX軸に平行な直線状をなし、その直線状の部位の終端からは上方に立ち上がるような部分円弧状をなす。さらに、その部分円弧状の部位の終端に連なる側壁313bの後端縁は、第二ケース部材22に向かって延びるようなZ軸に対してやや傾いた直線状をなす。
The outer edge of the cutter housing 313, that is, the outer edge of the driving body 3 (and the main body 1) is the lower end edge of the top wall 313 a of the cutter housing 313, the lower end edge of the pair of side walls 313 b, and the second case member 22 side. ) Formed by the trailing edge. When viewed from the Y-axis direction, the lower end edge of the side wall 313b forms a straight line parallel to the X axis so as to be in the same plane as the lower end edge of the top wall 313a at the portion connected to the lower end edge of the top wall 313a. It forms a partial arc shape that rises upward from the end of the shaped part. Further, the rear end edge of the side wall 313b connected to the terminal end of the partial arc-shaped portion forms a straight line slightly inclined with respect to the Z axis extending toward the second case member 22.
テープ42を切断するためのカッター刃314は、カッターハウジング313の内部に固定する。カッター刃314は、概ねZ軸方向に沿って基端から先端に向かって伸びる薄板の先端に刃先を付けた金属製のものである。図8ないし図11に示すように、カッター刃314は、刃先を含めて、駆動体3の先端部であるカッターハウジング313の外縁よりも没入した位置にある。即ち、刃先がカッターハウジング313から飛び出していない。
The cutter blade 314 for cutting the tape 42 is fixed inside the cutter housing 313. The cutter blade 314 is made of metal in which a blade tip is attached to the distal end of a thin plate extending from the proximal end toward the distal end generally along the Z-axis direction. As shown in FIGS. 8 to 11, the cutter blade 314 is located at a position that is deeper than the outer edge of the cutter housing 313 that is the tip of the drive body 3 including the blade edge. That is, the cutting edge does not protrude from the cutter housing 313.
副フレーム32は、Z軸方向に沿って伸長した副フレームベース321と、副フレームベース321に支持させた一対の挟持部材322、323とを備える。
The sub frame 32 includes a sub frame base 321 extending along the Z-axis direction and a pair of clamping members 322 and 323 supported by the sub frame base 321.
副フレームベース321は、主フレームベース311の内部に収容され、主フレームベース311及びカバー312に囲繞された状態で配置される。副フレーム32が主フレーム31に対してスライドするとき、副フレームベース321のY軸方向を向く外面が主フレームベース311の各側壁311bの内面に対して摺動し、X軸方向を向く外面が主フレームベース311の側壁311bの内面及びカバー312の内面に対して摺動する。
The sub-frame base 321 is housed inside the main frame base 311 and is disposed in a state surrounded by the main frame base 311 and the cover 312. When the sub-frame 32 slides relative to the main frame 31, the outer surface facing the Y-axis direction of the sub-frame base 321 slides against the inner surface of each side wall 311b of the main frame base 311 and the outer surface facing the X-axis direction The main frame base 311 slides on the inner surface of the side wall 311 b and the inner surface of the cover 312.
副フレームベース321のZ軸方向に沿った中間部位には、当該副フレームベース321をX軸方向に貫通し、かつZ軸方向に沿って拡張した開口321aを形成している。副フレームベース321を主フレームベース311の内部に収容する際、この開口321a内に主フレームベース311のストッパ311i及びスプリングリテーナ311jを差し入れる。これに加えて、開口321a内には、弾性付勢部材である圧縮コイルスプリング33を配置する。コイルスプリング33は、Z軸方向に沿って伸縮することを通じ、主フレーム31、副フレーム32及びリンク部材34を原位置(テープ42を貼付するときの位置)に復帰させる方向に付勢する弾性付勢力を発揮する。コイルスプリング33のZ軸方向に沿った先端側の端部は、開口321aのZ軸方向に沿った先端側の(反先端側を向いた)端面に当接させる。同コイルスプリング33の反先端側の端部は、主フレームベース311のストッパ311iに支持させたスプリングリテーナ311jに組み付ける。換言すれば、コイルスプリング33内にスプリングリテーナ311jの軸部分を挿入する。
An opening 321a that penetrates the sub-frame base 321 in the X-axis direction and extends in the Z-axis direction is formed in an intermediate portion along the Z-axis direction of the sub-frame base 321. When the sub frame base 321 is accommodated in the main frame base 311, the stopper 311 i and the spring retainer 311 j of the main frame base 311 are inserted into the opening 321 a. In addition, a compression coil spring 33, which is an elastic biasing member, is disposed in the opening 321a. The coil spring 33 is elastically urged in a direction to return the main frame 31, the sub frame 32, and the link member 34 to the original positions (positions when the tape 42 is applied) by expanding and contracting along the Z-axis direction. Demonstrate power. The end of the coil spring 33 on the front end side along the Z-axis direction is brought into contact with the end surface of the opening 321a on the front end side (facing the opposite end side) along the Z-axis direction. The opposite end of the coil spring 33 is assembled to a spring retainer 311j supported by a stopper 311i of the main frame base 311. In other words, the shaft portion of the spring retainer 311j is inserted into the coil spring 33.
副フレームベース321のZ軸方向に沿った先端側には、Y軸方向を向くとともに互いに平行に並立する一対の支持壁321bを設けている。これら支持壁321bは、カッターハウジング313の頂壁313a及び側壁313bに包囲された内部に進入する。副フレーム32が主フレーム31に対してスライドするとき、各支持壁321bの外面が、これに近接するカッターハウジング313の各側壁313bの内面に対して摺動する。支持壁321b(及び、副フレーム32)の先端部には、Y軸方向に伸長するローラ軸325を介してローラ324を支持させる。ローラ324は、テープ42を貼付対象物に圧着するための圧着部材となる。ローラ324は、ローラ軸325を中心として回動可能とすることが好ましい。ローラ324は、一対の支持壁321bの間、ひいてはカッターハウジング313の一対の側壁313bの間に所在する。リール41から引き出されたテープ42は、カラー312cの近傍で90°捻られた後、このローラ324に巻き掛けられた上で、カッターハウジング313の頂壁313aの下端縁まで導かれる。ローラ324の外周面は、テープ42の表面と接する。ローラ324は、例えばシリコン等を用いて作製する。
A pair of support walls 321b facing the Y axis direction and juxtaposed in parallel to each other are provided on the distal end side along the Z axis direction of the sub frame base 321. These support walls 321b enter the inside of the cutter housing 313 surrounded by the top wall 313a and the side wall 313b. When the sub frame 32 slides with respect to the main frame 31, the outer surface of each support wall 321b slides with respect to the inner surface of each side wall 313b of the cutter housing 313 adjacent thereto. A roller 324 is supported at the tip of the support wall 321b (and the sub-frame 32) via a roller shaft 325 extending in the Y-axis direction. The roller 324 serves as a crimping member for crimping the tape 42 to the object to be pasted. The roller 324 is preferably rotatable about the roller shaft 325. The roller 324 is located between the pair of support walls 321b and thus between the pair of side walls 313b of the cutter housing 313. The tape 42 pulled out from the reel 41 is twisted by 90 ° in the vicinity of the collar 312 c, wound around the roller 324, and then guided to the lower end edge of the top wall 313 a of the cutter housing 313. The outer peripheral surface of the roller 324 is in contact with the surface of the tape 42. The roller 324 is manufactured using, for example, silicon.
一対の挟持部材322、323は、テープ42における貼付部位とリール41との間に介在する中間部位を挟持する挟持機構を構成する。これら挟持部材322、323は、副フレームベース321にとともに、ケース2及び主フレーム31に対しZ軸方向に沿ってスライドする。その上で、X軸方向に沿って相互に接近/離間するように動作して、テープ42を表裏面両側から挟持する。
The pair of sandwiching members 322 and 323 constitute a sandwiching mechanism that sandwiches an intermediate part interposed between the sticking part of the tape 42 and the reel 41. These clamping members 322 and 323 slide along the Z-axis direction with respect to the case 2 and the main frame 31 together with the sub-frame base 321. Then, the tape 42 is clamped from both the front and back sides by operating so as to approach / separate each other along the X-axis direction.
一対の挟持部材322、323のうちの可動の挟持部材322は、副フレームベース321が主フレーム31に対しZ軸方向に沿って相対的に変位するのに伴い、副フレームベース321に対してX軸方向に沿って相対的に変位する。詳述すると、可動の挟持部材322は、X軸方向を向いた基板部322aと、この基板部322aの一方の側縁からX軸方向に沿って延出した側板部322bと、側板部322bの外面からY軸方向に沿って突出した突起322cと、基板部322aから駆動部(及び、本体1)の先端部に向かうように延出した押さえ部322dとを有する。
The movable clamping member 322 of the pair of clamping members 322 and 323 has an X relative to the sub-frame base 321 as the sub-frame base 321 is relatively displaced along the Z-axis direction with respect to the main frame 31. It is relatively displaced along the axial direction. More specifically, the movable clamping member 322 includes a substrate portion 322a facing in the X-axis direction, a side plate portion 322b extending along the X-axis direction from one side edge of the substrate portion 322a, and a side plate portion 322b. A protrusion 322c that protrudes from the outer surface along the Y-axis direction, and a pressing portion 322d that extends from the substrate portion 322a toward the tip of the drive portion (and the main body 1).
可動の挟持部材322の側板部322bは、副フレームベース321のY軸方向を向いた一方の外側面に形成したガイド321cに係合し、このガイド321cに沿ってX軸方向にスライドする。また、可動の挟持部材322を副フレームベース321とともに主フレームベース311の内部に収容した状態では、その側板部322bの外面が主フレームベース311の一方の側壁311bの内面に当接または近接するとともに、その突起322cが当該側壁311bに穿たれた長孔311e内に挿入される。つまり、可動の挟持部材322の変位の軌跡が、長孔311eの周縁によって制御される。副フレームベース321が主フレーム31に対し、先端側から反先端側に向かう方向に変位するためには、可動の挟持部材322の突起322cが、略L字型をなす長孔311eにおけるX軸方向に沿って拡張する部分311gから、Z軸方向に沿って延伸する部分311fへと遷移しなければならない。その過程で、可動の挟持部材322が、第二ケース部材22側から第一ケース部材21側に向かって、X軸方向に沿って変位することとなる。
The side plate portion 322b of the movable holding member 322 engages with a guide 321c formed on one outer surface of the sub-frame base 321 facing the Y-axis direction, and slides along the guide 321c in the X-axis direction. When the movable holding member 322 is housed in the main frame base 311 together with the sub-frame base 321, the outer surface of the side plate portion 322b is in contact with or close to the inner surface of one side wall 311b of the main frame base 311. The protrusion 322c is inserted into the long hole 311e formed in the side wall 311b. That is, the locus of displacement of the movable holding member 322 is controlled by the peripheral edge of the long hole 311e. In order for the sub-frame base 321 to be displaced in the direction from the front end side toward the non-front end side with respect to the main frame 31, the protrusion 322c of the movable clamping member 322 is in the X-axis direction in the long hole 311e having a substantially L shape The transition from the portion 311g extending along the Z axis direction to the portion 311f extending along the Z-axis direction has to be made. In the process, the movable clamping member 322 is displaced along the X-axis direction from the second case member 22 side toward the first case member 21 side.
可動の挟持部材322に一体成形された押さえ部322dは、カッター刃314によってテープ42を切断したときに、リール41から引き出されているテープ42の端部がばたつくことを抑制する働きをする。押さえ部322dは、基板部322aから一旦Z軸方向に沿って進出した後、第一ケース部材21側に向かうようにZ軸方向に対してやや傾いた方向に伸長する。
The pressing portion 322d formed integrally with the movable holding member 322 functions to prevent the end portion of the tape 42 drawn from the reel 41 from flapping when the tape 42 is cut by the cutter blade 314. The pressing portion 322d extends from the substrate portion 322a along the Z-axis direction, and then extends in a direction slightly inclined with respect to the Z-axis direction so as to go to the first case member 21 side.
他方、固定の挟持部材323は、可動の挟持部材322と異なり、(副フレームベース321が主フレーム31に対しZ軸方向に沿って変位したとしても)原則として副フレームベース321に対して変位しない。固定の挟持部材323の基板部323aは、X軸方向に沿って可動の挟持部材322と対向する。固定の挟持部材323の基板部323aは第一ケース部材21側にあり、可動の挟持部材322の基板部322aは第二ケース部材22側にある。そして、両基板部322a、323aにより、テープ42をX軸方向に沿った両側から挟み付ける。粘着剤または接着剤が塗布されたテープ42の裏面に面する都合上、可動の挟持部材322の基板部322aには例えばシリコン等の素材を用いて作製したパッド326を装着しておき、このパッド326がテープ42の裏面に当接するようにする。同様に、固定の挟持部材323の基板部323aにも、例えばシリコン等の素材を用いて作製したパッド326を装着しておき、このパッド326がテープ42の表面に当接するようにする。
On the other hand, the fixed clamping member 323 is not displaced with respect to the sub-frame base 321 in principle (even if the sub-frame base 321 is displaced along the Z-axis direction with respect to the main frame 31), unlike the movable clamping member 322. . The substrate portion 323a of the fixed clamping member 323 faces the movable clamping member 322 along the X-axis direction. The board part 323a of the fixed clamping member 323 is on the first case member 21 side, and the board part 322a of the movable clamping member 322 is on the second case member 22 side. Then, the tape 42 is sandwiched from both sides along the X-axis direction by the two substrate portions 322a and 323a. For the convenience of facing the back surface of the tape 42 to which the adhesive or adhesive is applied, a pad 326 made of a material such as silicon is attached to the substrate portion 322a of the movable holding member 322, and this pad is attached. 326 is in contact with the back surface of the tape 42. Similarly, a pad 326 made of a material such as silicon is mounted on the substrate portion 323 a of the fixed holding member 323 so that the pad 326 contacts the surface of the tape 42.
但し、厳密には、固定の挟持部材323を副フレームベース321に対して完全に固定してはいない。固定の挟持部材323の基板部323aは、その裏側(可動の挟持部材322の基板部322aとは反対側)に配置した圧縮コイルスプリング327によりバックアップされる。X軸方向に沿って第一ケース部材21側に向かう可動の挟持部材322の基板部322aが固定の挟持部材323の基板部323aを強く押圧したときには、このコイルスプリング327が弾性変形して、固定の挟持部材323の基板部323aをX軸方向に沿って第一ケース部材21側に後退させる。
However, strictly speaking, the fixed clamping member 323 is not completely fixed to the sub-frame base 321. The substrate portion 323a of the fixed holding member 323 is backed up by a compression coil spring 327 disposed on the back side thereof (the side opposite to the substrate portion 322a of the movable holding member 322). When the substrate portion 322a of the movable holding member 322 moving toward the first case member 21 along the X-axis direction strongly presses the substrate portion 323a of the fixed holding member 323, the coil spring 327 is elastically deformed and fixed. The substrate portion 323a of the holding member 323 is moved backward toward the first case member 21 along the X-axis direction.
リンク部材34は、駆動体3をケース2内に押し込もうとする操作力を、テープ42の中間部位を挟持した挟持機構をカッター刃314に対して相対的に変位させる力に変換する操作力変換機構を構成する。本実施形態にあって、リンク部材34は、駆動体3の要素である主フレーム31及び副フレーム32のケース2に対するZ軸方向に沿ったスライドを連動させながら、副フレーム32の主フレーム31に対するZ軸方向に沿った相対変位を惹起する。リンク部材34は、X軸方向を向く支軸311kを中心として回動する棒状の部材である。リンク部材34の一方の端部は、第一ケース部材21に設けた被係合部213に係合させる。第一ケース部材21の被係合部213は、リンク部材34の一方の端部が第一ケース部材21に対しZ軸方向に沿って相対的に変位することを禁ずるが、Y軸方向に沿って変位することは許容する。リンク部材34の他方の端部は、副フレームベース321の反先端側に設けた被係合部321dに係合させる。副フレームベース321の被係合部321dもまた、リンク部材34の他方の端部が副フレーム32に対しZ軸方向に沿って相対的に変位することを禁ずるが、Y軸方向に沿って変位することは許容する。図8及び図10に示すように、X軸方向から見て、リンク部材34の回転中心から一方の端部までの距離は、リンク部材34の回転中心から他方の端部までの距離よりも若干短い。
The link member 34 converts an operating force for pushing the driving body 3 into the case 2 into an operating force for displacing the clamping mechanism that clamps the intermediate portion of the tape 42 relative to the cutter blade 314. Configure the conversion mechanism. In the present embodiment, the link member 34 moves the slide of the main frame 31 and the sub frame 32 that are elements of the driving body 3 along the Z-axis direction with respect to the case 2 while interlocking with the main frame 31 of the sub frame 32. A relative displacement along the Z-axis direction is induced. The link member 34 is a rod-shaped member that rotates around a support shaft 311k facing the X-axis direction. One end of the link member 34 is engaged with an engaged portion 213 provided on the first case member 21. The engaged portion 213 of the first case member 21 prohibits one end of the link member 34 from being relatively displaced along the Z-axis direction with respect to the first case member 21, but along the Y-axis direction. Is allowed to displace. The other end portion of the link member 34 is engaged with an engaged portion 321 d provided on the opposite end side of the sub-frame base 321. The engaged portion 321d of the sub-frame base 321 also prohibits the other end of the link member 34 from being displaced relative to the sub-frame 32 along the Z-axis direction, but is displaced along the Y-axis direction. It is permissible to do. As shown in FIGS. 8 and 10, when viewed from the X-axis direction, the distance from the rotation center of the link member 34 to one end is slightly larger than the distance from the rotation center of the link member 34 to the other end. short.
本テープディスペンサの使用方法を述べる。駆動体3の先端部に外力が作用していないとき、駆動体3の要素である主フレーム31、副フレーム32及びリンク部材34はそれぞれ、図8及び図9に示している原位置にある。このとき、駆動体3の先端部を形成するカッターハウジング313が、ケース2の先端側から大きく露出している。なおかつ、図8に示すように、X軸方向から見て、テープ42が巻き掛けられたローラ324の少なくとも一部が、カッターハウジング313の外縁から外方に突出している。カッターハウジング313の頂壁313aの下端縁とローラ324の外周とを結ぶ接線、即ちテープ42の軌跡はX軸に平行であり、カッター刃314と交差しない。
】 Describe how to use this tape dispenser. When no external force is applied to the distal end portion of the driving body 3, the main frame 31, the sub frame 32, and the link member 34, which are elements of the driving body 3, are in their original positions shown in FIGS. At this time, the cutter housing 313 that forms the distal end portion of the drive body 3 is largely exposed from the distal end side of the case 2. In addition, as shown in FIG. 8, at least a part of the roller 324 around which the tape 42 is wound protrudes outward from the outer edge of the cutter housing 313 when viewed from the X-axis direction. A tangent line connecting the lower end edge of the top wall 313a of the cutter housing 313 and the outer periphery of the roller 324, that is, the trajectory of the tape 42 is parallel to the X axis and does not intersect the cutter blade 314.
また、主フレーム31のストッパ311iが、副フレーム32に形成した開口321aの反先端側の(先端側を向いた)端面に当接しており、ストッパ311iと開口321aとの間に介在する圧縮コイルスプリング33の長さが最大となる。可動の挟持部材322の突起322cは、主フレーム31の長孔311eにおける、X軸方向に沿って拡張する部分311gに所在する。加えて、図9に示すように、Y軸方向から見て、可動の挟持部材322の基板部322aと固定の挟持部材323の基板部323aとは離間しており、両挟持部材322、323によってテープ42が挟持されていない。並びに、押さえ部322dのX軸方向の位置が、ローラ324の外周よりも第二ケース部材22側にあって、当該押さえ部322dはテープ42に接触していない。
Further, the stopper 311i of the main frame 31 is in contact with the end surface of the opening 321a formed on the subframe 32 on the opposite end side (facing the tip side), and is a compression coil interposed between the stopper 311i and the opening 321a. The length of the spring 33 is maximized. The protrusion 322c of the movable holding member 322 is located in a portion 311g that extends along the X-axis direction in the long hole 311e of the main frame 31. In addition, as shown in FIG. 9, the substrate portion 322 a of the movable holding member 322 and the substrate portion 323 a of the fixed holding member 323 are separated from each other when viewed from the Y-axis direction. The tape 42 is not clamped. In addition, the position of the pressing portion 322 d in the X-axis direction is closer to the second case member 22 than the outer periphery of the roller 324, and the pressing portion 322 d is not in contact with the tape 42.
本テープディスペンサを使用してテープ42を貼付対象物に貼付しようとする使用者は、図1、図8及び図9に示している通り、本体1のケース2を把持して駆動体3の先端部を下に向けつつ、(必要ならばケース2を垂直よりもやや傾けて)ローラ324を貼付対象物に当てる。これにより、リール41から繰り出されているテープ42がローラ324と貼付対象物との間に挟まれる。この状態で、使用者がケース2をX軸方向に沿って(図9中の右方に)引く操作を行うことで、ローラ324が回動しながらその直下にあるテープ42を貼付対象物に圧着しつつ、新たなテープ42を順次リール41から引き出すことができる。結果、X軸方向に沿って所望の長さのテープ42が貼付対象物に貼付される。
A user who intends to apply the tape 42 to an object to be applied using the tape dispenser grips the case 2 of the main body 1 and holds the tip of the driving body 3 as shown in FIGS. The roller 324 is applied to the object to be pasted with the part facing downward (if necessary, the case 2 is slightly inclined from the vertical). As a result, the tape 42 fed out from the reel 41 is sandwiched between the roller 324 and the object to be pasted. In this state, the user pulls the case 2 along the X-axis direction (to the right in FIG. 9), so that the tape 42 immediately below the roller 324 is rotated as the object to be pasted. New tapes 42 can be sequentially pulled out from the reels 41 while being crimped. As a result, the tape 42 having a desired length is attached to the object to be attached along the X-axis direction.
テープ42の貼付対象物への貼付後、テープ42を切断しようとする使用者は、把持しているケース2を垂直に立て、カッターハウジング313の頂壁313aの下端縁を貼付対象物に当てる。これにより、貼付対象物に貼付されたテープ42の貼付部位が、カッターハウジング313の頂壁313a及び側壁313bと貼付対象物との間に挟まれる。その状態で、ケース2を貼付対象物(または、貼付対象物を載置している机の天板等)に強く押し付けるようにしてケース2を移動させる操作を行うと、貼付対象物側からカッターハウジング313の頂壁313a及び側壁313bに、駆動体3をケース2内に押し込もうとする操作力が印加される。
After the tape 42 is applied to the object to be applied, the user who wants to cut the tape 42 stands the case 2 being held vertically and applies the lower end edge of the top wall 313a of the cutter housing 313 to the object to be applied. Thereby, the sticking site | part of the tape 42 stuck on the sticking target object is pinched | interposed between the top wall 313a and the side wall 313b of the cutter housing 313, and the sticking target object. In this state, when the case 2 is moved so that the case 2 is strongly pressed against the object to be attached (or the top plate of the desk on which the object to be attached is placed), the cutter 2 is cut from the object to be attached. An operating force for pushing the driving body 3 into the case 2 is applied to the top wall 313a and the side wall 313b of the housing 313.
上記の操作力はまず、駆動体3の要素である主フレーム31を、ケース2に対し、Z軸方向に沿って先端側から反先端側に向かって相対的に変位させる。主フレーム31がケース2内に押し込まれることから、カッターハウジング313がケース2から突出する量が原位置と比較して小さくなることは言うまでもない。リール41は、主フレーム31とともにZ軸方向に沿って変位するので、カッター刃314とリール41との相対的な位置関係は変化しない。しかして、主フレーム31に設けた支軸311kがケース2に対しZ軸方向に沿って反先端側に相対変位することで、一方の端部を第一ケース部材21の被係合部213に係合させているリンク部材34が、支軸311kを中心として(図8及び図10中時計回りに)回動する。このため、副フレーム32の被係合部321dに係合しているリンク部材34の他方の端部が、ケース2に対し、Z軸方向に沿って支軸311kよりも大きく変位することとなる。つまり、主フレーム31がケース2に対しZ軸方向に沿って相対変位する(ケース2内に押し込まれる)とき、副フレーム32もまたケース2に対しZ軸方向に沿って相対変位し、その変位量は主フレーム31のそれよりも大きくなる。要するに、上記の操作力は、駆動体3の要素である副フレーム32を、主フレーム31に対し、Z軸方向に沿って先端側から反先端側に向かって相対的に変位させる。
First, the above-described operating force displaces the main frame 31 that is an element of the driving body 3 relative to the case 2 from the tip side toward the opposite tip side along the Z-axis direction. Needless to say, since the main frame 31 is pushed into the case 2, the amount by which the cutter housing 313 protrudes from the case 2 is smaller than the original position. Since the reel 41 is displaced along the Z-axis direction together with the main frame 31, the relative positional relationship between the cutter blade 314 and the reel 41 does not change. Thus, the support shaft 311k provided on the main frame 31 is relatively displaced to the opposite end side along the Z-axis direction with respect to the case 2, so that one end thereof is engaged with the engaged portion 213 of the first case member 21. The engaged link member 34 rotates around the support shaft 311k (clockwise in FIGS. 8 and 10). For this reason, the other end portion of the link member 34 engaged with the engaged portion 321d of the sub frame 32 is displaced more than the support shaft 311k along the Z-axis direction with respect to the case 2. . That is, when the main frame 31 is displaced relative to the case 2 along the Z-axis direction (pressed into the case 2), the sub-frame 32 is also displaced relative to the case 2 along the Z-axis direction. The amount is larger than that of the main frame 31. In short, the operation force described above displaces the sub-frame 32 that is an element of the driving body 3 relative to the main frame 31 from the front end side toward the non-front end side along the Z-axis direction.
副フレーム32が主フレーム31に対しZ軸方向に沿って反先端側に相対変位する結果、図10及び図11に示しているように、副フレーム32に支持させたローラ324及び挟持部材322、323が、主フレーム31に支持させたカッター刃314から離反するように変位する。図10に示すように、X軸方向から見て、ローラ324がカッターハウジング313の外縁よりも没入するように退避すると、カッターハウジング313の頂壁313aの下端縁とローラ324の外周とを結ぶ接線、即ちテープ42の軌跡がX軸に平行でなくなり、カッター刃314と交差するようになる。即ち、ローラ324がテープ42をカッター刃314の刃先に当てることの妨げとならなくなる。また、主フレーム31のストッパ311iが、副フレーム32に形成した開口321aの反先端側の端面から離間し、ストッパ311iと開口321aとの間に介在する圧縮コイルスプリング33の長さを縮小させる。
As a result of the relative displacement of the subframe 32 relative to the main frame 31 along the Z-axis direction, as shown in FIGS. 10 and 11, the roller 324 and the clamping member 322 supported by the subframe 32, 323 is displaced away from the cutter blade 314 supported by the main frame 31. As shown in FIG. 10, the tangent line connecting the lower end edge of the top wall 313 a of the cutter housing 313 and the outer periphery of the roller 324 when the roller 324 is retracted so as to be recessed from the outer edge of the cutter housing 313 when viewed from the X-axis direction. That is, the trajectory of the tape 42 is not parallel to the X axis and intersects with the cutter blade 314. That is, the roller 324 does not prevent the tape 42 from being applied to the cutting edge of the cutter blade 314. Further, the stopper 311i of the main frame 31 is separated from the end surface on the opposite end side of the opening 321a formed in the sub-frame 32, and the length of the compression coil spring 33 interposed between the stopper 311i and the opening 321a is reduced.
しかも、副フレーム32が主フレーム31に対しZ軸方向に沿って反先端側に相対変位することで、可動の挟持部材322の突起322cが、主フレーム31の長孔311eにおけるX軸方向に沿って拡張する部分311gから、湾曲部分311hを経由し、Z軸方向に沿って延伸する部分311fへと遷移する。これにより、図11に示すように、可動の挟持部材322の基板部322aがX軸方向に沿って固定の挟持部材323の基板部323aに向かって変位するため、両基板部322a、323a(のパッド326)が当接し、これらがテープ42における貼付部位とリール41との間に介在する中間部位を表裏両面側から強力に挟圧する。その上で、副フレーム32が主フレーム31に対しZ軸方向に沿ってさらに変位すると、テープ42の中間部位を挟持した挟持部材322、323がZ軸方向に沿ってカッター刃314から離反することになる。
In addition, the sub-frame 32 is displaced relative to the main frame 31 in the opposite direction along the Z-axis direction, so that the protrusion 322c of the movable clamping member 322 extends along the X-axis direction in the long hole 311e of the main frame 31. The portion 311g that expands through the curved portion 311h makes a transition to the portion 311f that extends along the Z-axis direction. As a result, as shown in FIG. 11, the substrate portion 322a of the movable holding member 322 is displaced toward the substrate portion 323a of the fixed holding member 323 along the X-axis direction. The pads 326) come into contact with each other, and strongly press the intermediate portion interposed between the sticking portion of the tape 42 and the reel 41 from both the front and back sides. Then, when the sub-frame 32 is further displaced along the Z-axis direction with respect to the main frame 31, the clamping members 322 and 323 that sandwich the intermediate portion of the tape 42 are separated from the cutter blade 314 along the Z-axis direction. become.
同時に、可動の挟持部材322に一体成形している押さえ部322dのX軸方向の位置が、ローラ324の外周よりも第一ケース部材21側に変位する。即ち、当該押さえ部322dが、基板部322a、323aとローラ324の外周とを結ぶ接線よりも第一ケース部材21側に迫り出し、テープ42に接触する。
At the same time, the position in the X-axis direction of the pressing portion 322 d formed integrally with the movable holding member 322 is displaced from the outer periphery of the roller 324 toward the first case member 21. That is, the pressing portion 322 d protrudes closer to the first case member 21 than the tangent line connecting the substrate portions 322 a and 323 a and the outer periphery of the roller 324 and comes into contact with the tape 42.
ローラ324がカッターハウジング313の外縁よりも没入するように退避することは、ローラ324に巻き掛けていたテープ42を弛ませることにつながるが、その分だけ挟持部材322が第一ケース部材21側に迫り出すことで、ローラ324とリール41との間におけるテープ42の軌跡を屈曲させ、テープ42に張力を付与するので、カッター刃314の刃先に当てるべきテープ42が弛むことが回避される。
Retraction of the roller 324 so as to be immersed more than the outer edge of the cutter housing 313 leads to loosening the tape 42 wound around the roller 324, but the holding member 322 is moved closer to the first case member 21. By projecting, the trajectory of the tape 42 between the roller 324 and the reel 41 is bent and tension is applied to the tape 42, so that the tape 42 to be applied to the cutting edge of the cutter blade 314 is prevented from being loosened.
総合すると、使用者がケース2を貼付対象物に向けて移動させる操作を行うことにより、副フレーム32が主フレーム31に対しZ軸方向に沿って反先端側に相対変位し、可動の挟持部材322がX軸方向に沿って第一ケース部材21側に変位して、挟持部材322(の基板部322a)が第一ケース部材21側に向けてテープ42を押圧して張力を付与する。のみならず、挟持部材322、323がテープ42の中間部位を挟持した状態で、Z軸方向に沿ってカッター刃314から離反する方向に相対変位してテープ42に張力を付与する。従って、テープ42を緊張させたまま、弛ませたり歪ませたりすることなくカッター刃314の刃先に強く当てることが可能となり、テープ42が確実かつ美麗に切断されることとなる。
Overall, when the user performs an operation of moving the case 2 toward the object to be pasted, the sub-frame 32 is relatively displaced relative to the main frame 31 along the Z-axis direction toward the front end side, and a movable clamping member The 322 is displaced toward the first case member 21 along the X-axis direction, and the clamping member 322 (the substrate portion 322a) presses the tape 42 toward the first case member 21 to apply tension. In addition, with the clamping members 322 and 323 sandwiching the intermediate portion of the tape 42, the tape 42 is tensioned by relative displacement in the direction away from the cutter blade 314 along the Z-axis direction. Therefore, the tape 42 can be strongly applied to the cutting edge of the cutter blade 314 without being loosened or distorted while the tape 42 is in tension, and the tape 42 is cut surely and beautifully.
テープ42の切断に成功した暁には、ケース2を貼付対象物に押し付けるような操作を解除すればよい。さすれば、貼付対象物側からカッターハウジング313の頂壁313a及び側壁313bに印加されていた、駆動体3をケース2内に押し込もうとする操作力が消失する。そして、圧縮されていたコイルスプリング33が発揮する弾性付勢力により、副フレーム32が、主フレーム31に対し、Z軸方向に沿って反先端側から先端側に向かって相対変位する。なおかつ、リンク部材34が支軸311kを中心として(図8及び図10中反時計回りに)回動し、ケース2内に押し込まれていた主フレーム31が、ケース2に対し、Z軸方向に沿って反先端側から先端側に向かって相対的に変位する。最終的に、主フレーム31、副フレーム32及びリンク部材34がそれぞれ、図8及び図9に示す原位置に復帰する。
When the tape 42 has been successfully cut, the operation of pressing the case 2 against the object to be pasted may be canceled. Then, the operation force that is applied to the top wall 313a and the side wall 313b of the cutter housing 313 from the sticking object side and tries to push the driving body 3 into the case 2 disappears. Then, due to the elastic biasing force exerted by the compressed coil spring 33, the sub-frame 32 is displaced relative to the main frame 31 from the non-tip side toward the tip side along the Z-axis direction. Further, the link member 34 rotates about the support shaft 311k (counterclockwise in FIGS. 8 and 10), and the main frame 31 pushed into the case 2 moves in the Z-axis direction with respect to the case 2. Along the direction from the front end side to the front end side, it is relatively displaced. Finally, the main frame 31, the sub frame 32, and the link member 34 are returned to the original positions shown in FIGS.
また、主フレーム31、副フレーム32及びリンク部材34が原位置に復帰する際に、可動の挟持部材322の突起322cが、長孔311eにおけるZ軸方向に沿って延伸する部分311fから、X軸方向に沿って拡張する部分311gへと遷移する。その過程で、可動の挟持部材322が、第一ケース部材21側から第二ケース部材22側に向かって、X軸方向に沿って変位する。即ち、可動の挟持部材322の基板部322aが固定の挟持部材323の基板部323aから離間してテープ42の挟持が解消されるとともに、挟持部材322がテープ42を押圧しなくなる。
Further, when the main frame 31, the sub frame 32, and the link member 34 are returned to the original positions, the protrusion 322c of the movable holding member 322 extends from the portion 311f extending along the Z-axis direction in the long hole 311e to the X axis. It changes to the part 311g which expands along a direction. In the process, the movable clamping member 322 is displaced along the X-axis direction from the first case member 21 side toward the second case member 22 side. That is, the substrate portion 322a of the movable holding member 322 is separated from the substrate portion 323a of the fixed holding member 323 so that the holding of the tape 42 is eliminated and the holding member 322 does not press the tape 42.
本実施形態では、貼付対象物にテープ42を貼付する際に用いられるテープディスペンサであって、テープ42が巻き回されたリール41を保持する本体1と、リール41から引き出されたテープ42を切断するためのカッター刃314と、リール41から引き出されたテープ42をカッター刃314に当てて切断するときに、テープ42における貼付対象物に貼付された貼付部位とリール41との間に介在する中間部位を挟持した状態でカッター刃314に対して相対的に変位する挟持機構とを具備するテープディスペンサを構成した。
In this embodiment, it is a tape dispenser used when sticking the tape 42 on the sticking object, and the main body 1 holding the reel 41 around which the tape 42 is wound, and the tape 42 drawn from the reel 41 are cut. When the cutting blade 314 for cutting and the tape 42 pulled out from the reel 41 are applied to the cutter blade 314 and cut, the intermediate portion interposed between the application portion of the tape 42 attached to the object to be applied and the reel 41. A tape dispenser having a clamping mechanism that is displaced relative to the cutter blade 314 in a state where the part is clamped was configured.
本実施形態によれば、テープ42を貼付対象物に貼付した後、テープ42を切断する作業を確実かつ簡便に行い得るテープディスペンサを実現できる。即ち、挟持機構の動作を通じて、テープ42における貼付部位と中間部位との間を緊張させながらカッター刃314の刃先にしっかりと当てることができるので、リール41から引き出されたテープ42が弛んでカッター刃314に上手く当たらなかったり、カッター刃314がテープ42を裁断する最中にテープ42が歪んでしまい綺麗に切れなかったりする問題が回避される。
According to the present embodiment, it is possible to realize a tape dispenser that can reliably and easily perform the work of cutting the tape 42 after the tape 42 is applied to the object to be applied. That is, through the operation of the clamping mechanism, the tape 42 can be firmly applied to the cutting edge of the cutter blade 314 while tensioning between the pasting portion and the intermediate portion of the tape 42, so that the tape 42 pulled out from the reel 41 loosens and the cutter blade Problems such as failure to hit 314 well or tape 42 being distorted and not being cut cleanly while cutter blade 314 cuts tape 42 are avoided.
加えて、前記挟持機構が、テープ42を表裏両面側から挟む一対の挟持部材322、323を有しており、一方の挟持部材322が他方の挟持部材323に対して接近する過程で、当該挟持部材322と連動して変位する押圧部材322aがテープ42の貼付部位とリール41との間を押圧することで前記カッター刃314に当たるテープ42に張力を付与するため、押圧部材322aによるテープ42の押圧と、挟持部材322、323のカッター刃314に対する変位によるテープ42の緊張との相乗作用により、テープ42を弛ませたり歪ませたりことなくカッター刃314に当てることができ、切れにくい素材のテープ42であっても綺麗に切断することが可能になる。
In addition, the clamping mechanism has a pair of clamping members 322 and 323 that sandwich the tape 42 from both the front and back sides, and in the process where one clamping member 322 approaches the other clamping member 323, The pressing member 322a, which is displaced in conjunction with the member 322, presses between the sticking portion of the tape 42 and the reel 41 to apply tension to the tape 42 that hits the cutter blade 314. Therefore, the pressing member 322a presses the tape 42. And the tension of the tape 42 due to the displacement of the clamping members 322 and 323 with respect to the cutter blade 314, the tape 42 can be applied to the cutter blade 314 without being loosened or distorted. Even so, it becomes possible to cut cleanly.
前記本体1が、使用者が把持するケース2と、ケース2に対して相対的に変位可能でありその先端部がケース2から突出する駆動体3とを有しており、テープ42の貼付部位を貼付対象物に貼付した後に使用者がケース2を移動させる操作に起因して貼付対象物側から駆動体3の先端部に加わる、駆動体3をケース2内に押し込もうとする操作力を、テープ42の中間部位を挟持した前記挟持機構を前記カッター刃314に対して相対的に変位させる力に変換する操作力変換機構を具備するため、テープ42を切断するための操作が簡単となる。
The main body 1 has a case 2 gripped by a user and a drive body 3 that is displaceable relative to the case 2 and whose tip protrudes from the case 2. Operation force to push the driving body 3 into the case 2 applied to the tip of the driving body 3 from the pasting object side due to the operation of moving the case 2 by the user after pasting the object on the pasting object Is provided with an operating force conversion mechanism that converts the clamping mechanism that sandwiches the intermediate portion of the tape 42 into a force that is displaced relative to the cutter blade 314, and thus the operation for cutting the tape 42 is simple. Become.
前記駆動体3が、前記カッター刃314を支持する主フレーム31と、前記挟持機構を支持する副フレーム32とを有しており、前記操作力によって主フレーム31が前記ケース2に対して変位する変位量よりも副フレーム32がケース2に対して変位する変位量の方が大きくなるように、主フレーム31、副フレーム32及びケース2を連結するリンク部材34を設けることで、前記操作力変換機構を構成しているため、構造及び機構が簡便で、耐久性の向上及びコストの低減に資する。
The driving body 3 includes a main frame 31 that supports the cutter blade 314 and a sub-frame 32 that supports the clamping mechanism, and the main frame 31 is displaced with respect to the case 2 by the operation force. By providing the main frame 31, the sub-frame 32, and the link member 34 that connects the case 2 so that the amount of displacement of the sub-frame 32 relative to the case 2 is larger than the amount of displacement, the operation force conversion is performed. Since the mechanism is configured, the structure and the mechanism are simple, which contributes to improvement in durability and cost reduction.
前記カッター刃314を前記駆動体3の先端部に支持させており、そのカッター刃314が駆動体3の先端部の外縁よりも没入した位置にあるため、カッター刃314の刃先が貼付対象物に当接せず、カッター刃314により貼付対象物が損傷することがない。
Since the cutter blade 314 is supported by the tip of the driving body 3 and the cutter blade 314 is located at a position where it is immersed more than the outer edge of the tip of the driving body 3, the cutting edge of the cutter blade 314 is attached to the object to be pasted. The contact object is not damaged by the cutter blade 314 without contact.
リール41から引き出されたテープ42を貼付対象物に圧着させるために前記本体1の先端部の外縁から突出するとともに、テープ42をカッター刃314に当てて切断するときには当該外縁よりも没入するように退避する圧着部材324を具備するため、テープ42の切断時に圧着部材324を退避させてテープ42をカッター刃314の刃先にしっかりと強く当てることが可能となり、確実にテープ42を切断できるようになる。
The tape 42 pulled out from the reel 41 protrudes from the outer edge of the front end portion of the main body 1 in order to press the tape 42 against the object to be pasted, and when the tape 42 is cut against the cutter blade 314, the tape 42 is immersed more than the outer edge. Since the crimping member 324 is retracted, the crimping member 324 can be retracted when the tape 42 is cut so that the tape 42 can be firmly and strongly applied to the cutting edge of the cutter blade 314, and the tape 42 can be reliably cut. .
並びに、リール41から引き出されたテープ42を貼付対象物に圧着させるために前記本体1の先端部の外縁から突出するとともに、テープ42をカッター刃314に当てて切断するときには当該外縁よりも没入するように退避する圧着部材324を、前記副フレーム32に支持させているため、挟持機構の動作を実現する副フレーム32によって圧着部材324の退避をも具現できる。これにより、機構が徒に複雑化せず、部品点数も削減できる。
In addition, the tape 42 pulled out from the reel 41 protrudes from the outer edge of the front end portion of the main body 1 in order to press the tape 42 against the object to be pasted, and when the tape 42 is cut against the cutter blade 314, the tape 42 is immersed more than the outer edge. Since the crimping member 324 retracted is supported by the sub-frame 32, the crimping member 324 can be retracted by the sub-frame 32 that realizes the operation of the clamping mechanism. As a result, the mechanism is not complicated and the number of parts can be reduced.
また、本体1の先端部を構成するカッターハウジング313が透明であり、その頂壁313aにテープ42の貼付時及び切断時にテープを視認することのできる貫通窓313cも形成されていることから、貼付対象物へのテープ42の貼付を開始する位置、及びテープ42の貼付を終了してテープ42を切断する位置を、使用者が視認して明確に把握することができる。即ち、使用者の狙い通りの場所及び範囲にテープ42を貼付することが可能であって、利便性が高い。
Further, the cutter housing 313 constituting the tip of the main body 1 is transparent, and a through-window 313c through which the tape can be visually recognized is formed on the top wall 313a when the tape 42 is applied and cut. The user can clearly grasp the position where the application of the tape 42 to the object is started and the position where the application of the tape 42 is terminated and the tape 42 is cut. That is, it is possible to affix the tape 42 at a location and range as intended by the user, and the convenience is high.
なお、本発明は以上に詳述した実施形態に限られるものではない。例えば、テープ42は、表裏両面に粘着剤または接着剤が塗布された両面テープであってもよい。
Note that the present invention is not limited to the embodiment described in detail above. For example, the tape 42 may be a double-sided tape in which an adhesive or an adhesive is applied to both front and back surfaces.
上記実施形態では、カッター刃314を以てテープ42を切断するに際し、駆動体3の先端部であるカッターハウジング313の頂壁313a(の下端縁)と貼付対象物との間にテープ42の貼付部位を挟むようにしていたが、テープ42に塗布されている粘着剤の粘着力または接着剤の接着力が強い(あるいは、テープ42を貼付対象物に貼付してから時間が経過しており、テープ42の貼付部位が容易に貼付対象物から剥離し得ない)場合には、カッターハウジング313の頂壁313a(の下端縁)と貼付対象物とでテープ42の貼付部位を挟まずとも、カッター刃314に当てるテープ42を必要十分に緊張させることが可能である。この場合、カッター刃314の刃先を露出させないようにカッターハウジング313には側壁313bのみが存在していればよく、頂壁313a(または、その下端縁)を削除して窓313cを拡大させることも許される。
In the above embodiment, when the tape 42 is cut with the cutter blade 314, the application portion of the tape 42 is placed between the top wall 313a (the lower end edge) of the cutter housing 313, which is the tip of the drive body 3, and the object to be applied. The adhesive force of the adhesive applied to the tape 42 or the adhesive strength of the adhesive is strong (or time has elapsed since the tape 42 was applied to the object to be applied, and the tape 42 was applied. If the site cannot be easily peeled off from the object to be applied), it is applied to the cutter blade 314 without sandwiching the application part of the tape 42 between the top wall 313a of the cutter housing 313 (the lower end edge thereof) and the object to be applied. It is possible to tension the tape 42 as necessary and sufficiently. In this case, only the side wall 313b needs to be present in the cutter housing 313 so that the blade edge of the cutter blade 314 is not exposed, and the top wall 313a (or its lower edge) may be deleted to enlarge the window 313c. forgiven.
上記実施形態では、テープ42を切断するカッター刃314及びテープ42の中間部位を挟持する挟持機構の各々が本体1のケース2に対して(Z軸方向に沿って)相対変位していたが、何れか一方のみをケース2に対して相対変位させ、他方をケース2に対して変位させない態様をとることを妨げない。テープ42の中間部位を挟持してテープ42を緊張状態に保つ挟持機構をケース2に対して不動とし、その状態でカッター刃314をケース2及び挟持機構に対して相対的に変位させ、刃先をテープ42に強く押し当ててテープ42を切断するようにすることも当然に考えられる。
In the above embodiment, each of the cutter blade 314 that cuts the tape 42 and the clamping mechanism that clamps the intermediate portion of the tape 42 is relatively displaced (along the Z-axis direction) with respect to the case 2 of the main body 1. It is not prevented that only one of them is displaced relative to the case 2 and the other is not displaced relative to the case 2. The clamping mechanism that clamps the intermediate portion of the tape 42 and keeps the tape 42 in a tensioned state is immovable with respect to the case 2, and in this state, the cutter blade 314 is displaced relative to the case 2 and the clamping mechanism, and the cutting edge is moved. Naturally, it is also conceivable to press the tape 42 strongly to cut the tape 42.
上記実施形態では、使用者が把持しているケース2を貼付対象物に向かって押し付ける操作を通じて、リール41から引き出されたテープ42を挟持している挟持機構をカッター刃314に対して相対変位させる動作を惹起していたが、挟持機構及び挟持機構が挟持しているテープ42をカッター刃314に対して相対変位させるための操作の態様は、このようなものには限定されない。例えば、本体1またはケース2に対して相対的に変位可能なレバー、スライダ等の部材を本体1またはケース2に支持させるとともに、使用者が手指でこれを本体1またはケース2に対して変位させる操作を行ったときに、そのレバー等に加えられた操作力を、テープ42を挟持した状態の挟持機構をカッター刃314に対して相対的に変位させる力に変換する機構を設けておく。
In the above embodiment, the clamping mechanism that clamps the tape 42 drawn from the reel 41 is relatively displaced with respect to the cutter blade 314 through an operation of pressing the case 2 held by the user toward the object to be pasted. Although the operation has been triggered, the mode of operation for relatively displacing the clamping mechanism and the tape 42 held by the clamping mechanism with respect to the cutter blade 314 is not limited to this. For example, a member such as a lever or a slider that can be relatively displaced with respect to the main body 1 or the case 2 is supported by the main body 1 or the case 2, and the user displaces it with respect to the main body 1 or the case 2 with fingers. A mechanism is provided for converting the operation force applied to the lever or the like when the operation is performed into a force for displacing the clamping mechanism in a state where the tape 42 is clamped relative to the cutter blade 314.
テープ42の態様や用途もまた、上記実施形態におけるものには限定されない。テープ42の用途としては、いわゆる修正テープのように貼付対象物に書いてある文字や図形等を被覆して隠蔽できるもの(貼付対象物から剥離困難、または貼付対象物から一旦剥離すると再付着できない)や、付箋のように使用できるもの(テープ42の裏面の一部分にのみ粘着剤または接着剤が塗布される)、貼付後の剥離や再付着が可能なマスキングテープとして使用できるもの、透明なテープ42の幅寸法の一部にテープ42の延びる方向に沿った細線を(例えば、テープ42の一方の側縁に沿って、またはテープ42の幅方向の中心位置に)印刷しておき貼付対象物に貼付されることで下線や取消線を表現できるもの、等が考えられる。テープ42の幅寸法は、図示しているものよりも大きい(幅広である)可能性がある。
The aspect and use of the tape 42 are not limited to those in the above embodiment. The tape 42 can be used to cover and conceal characters or figures written on the object to be pasted, such as a so-called correction tape. ), Can be used like a sticky note (adhesive or adhesive is applied only to a part of the back side of the tape 42), can be used as a masking tape that can be peeled off and reattached after application, transparent tape A thin line along the direction in which the tape 42 extends (for example, along one side edge of the tape 42 or at the center position in the width direction of the tape 42) is printed on a part of the width dimension of the tape 42 It is possible to express an underline or strikethrough by being affixed to the. The width dimension of the tape 42 may be larger (wider) than shown.
その他各部の具体的構成は、本発明の趣旨を逸脱しない範囲で種々変形が可能である。
Other specific configurations of each part can be variously modified without departing from the gist of the present invention.
本発明は、貼付対象物にテープを貼付する際に用いられるテープディスペンサに適用することができる。
The present invention can be applied to a tape dispenser used when a tape is applied to an object to be applied.
