【０００１】
【産業上の利用分野】
本発明は、修正塗膜転写テープの塗膜を、消去したり文字上に転写せしめて、該文字を消去するために用いる字消し具の修正塗膜転写テープの供給リール装置に関するものである。
【０００２】
【従来の技術】
字消し具は、ケース内に修正塗膜転写テープの供給リールと巻取りリールを回動自在に設け、前記ケースの先端に塗膜転写ヘッドを突設し、供給リールは、前記ケースに設けた第一支軸に回動自在に枢支させた駆動歯車のボス部に繰出し円筒部を回動可能に係合して構成し、巻取りリールは前記ケースに設けた第二支軸に回動自在に枢支させた巻取り円筒部の外周に前記駆動歯車にかみ合う従動歯車を備え、前記繰出し円筒部と前記巻取り円筒部間の前記塗膜転写テープの中間部を、前記塗膜転写ヘッドで消去面に押し付けるようにした構造のものであるが、塗膜転写ヘッドで修正塗膜転写テープを供給リールより繰出しながら塗膜の転写操作（字消し操作）を行い、供給リールより繰出された修正塗膜転写テープは供給リールに歯車装置を介して連動した巻取りリールで巻取られるようになっている。
【０００３】
しかしながら、修正塗膜転写テープを使用するに伴い、必然的に供給リール側の巻回量より巻取りリール側の巻回量が増し、供給リール側の繰出し速度と巻取りリール側の巻取り速度とのバランスが崩れ（同期が崩れ）、塗膜の転写操作が円滑に行えなくなる。
【０００４】
このため、特開平５−５８０９７号公報所載のように、駆動歯車のボス部にＯリングを介して供給リールの繰出し円筒部を嵌装し、繰出し円筒部の内面をＯリングに接触させ、この接触により前記ボス部（駆動歯車）と繰出し円筒部（供給リール）が一体的に回動し、また、繰出しと巻取りの連度の同期が崩れたときはボス部に対して繰出し円筒部が滑り回動して前記両速度の同期を回復できるようにした構造のものが提案された。
【０００５】
【発明が解決しようとする課題】
前記従来例は、Ｏリング（エラストマー製）の繰出し円筒部による接触により該円筒部に回転を伝達させる構成を採るためにＯリングの素材による接触抵抗が大きく、従って、前記の同期を回復するための滑り回動動作が必ずしも円滑に行われない場合がある。
【０００６】
本発明は、従来例と較べ、繰出し操作が確実に行われ、かつ、ボス部に対する繰出し円筒部の滑り回動が良好に行われる供給リール装置を提供することを目的として創案したものである。
【０００７】
【課題を解決するための手段】
先端に塗膜転写ヘッドを突設したケース内に、修正塗膜転写テープの供給リールと巻取りリールを回動自在に設け、供給リールは、前記ケースに設けた第一支持軸に回動自在に枢支させた駆動歯車のボス部に、繰出し円筒部を回動可能に係合して構成する一方、巻取りリールは前記ケースに設けた第二支軸に回動自在に枢支させた巻取り円筒部の外周に沿わせて前記駆動歯車にかみ合う従動歯車を設けて構成し、前記繰出し円筒部と前記巻取り円筒部間の前記修正塗膜転写テープの中間部を、前記塗膜転写ヘッドで消去面に押し付けるようにした字消し具において、駆動歯車のボス部を第一支軸に回動自在に組付けた主筒と、該主筒の外周に沿わせて並設し、しかも、繰出し円筒部の内周面に弾性的に接触する、複数個の部片とで構成し、部片と前記主筒との間にはリング状のスペーサを嵌着した構成とする。
【０００８】
【実施例】
図面は本発明に係る字消し具における修正塗膜転写テープの供給リール装置の一実施例を示し、図１はケースを開放して示した一部欠截正面図、図２は図１のＸ−Ｘ線断面図である。
【０００９】
実施例の字消し具Ａは、一半部材１ａと他の一半部材１ｂに互いに嵌合し、一半部材１ｂに設けた窓口２に装置基板３を嵌合してケース１を構成し、該ケース１に、供給リール４と該供給リール４より繰出される修正塗膜転写テープａを連続的に巻取る巻取りリール５のそれぞれを前記装置基板３に軸支して収設し、装置基板３に基部を組付けた支持部材６の先端を、ケース１の先部側に配した断面方形状の筒状部７を通じて該筒状部７の開口先端より導出して、該先端に前記修正塗膜転写テープａの修正塗膜層を消去個所（紙面などの）に転写塗着させるための塗膜転写ヘッド８を設けて構成し、転写ヘッド８を用いて修正塗膜転写テープａを消去個所に押し付けた状態にして該転写テープａの長手方向沿いにケース１を適量移動させるようにすると、転写テープａは供給リール４より繰り出され、修正塗膜が剥離された用済みの転写テープ部は、歯車（後記）のかみ合いで供給リール４に連動した巻取りリール５に巻き取られ、消去個所上に修正塗膜が塗着して、所謂字消し操作（転写操作）が行われるようになっている。
【００１０】
前記供給リール４は、駆動歯車９のボス部１０に、該ボス部１０の外周側から繰出し円筒部１１を回動自在に係合して構成し、前記ボス部１０は、前記装置基板３に設けた第一支軸１２に回動自在に組付けた主筒１３と該主筒１３の外周に沿わせて並設した、複数個の部片１４、……とで構成し、主筒１３と部片１４、……との間には主筒１３に嵌着して弾性リングより成るスペーサ１５を介在させ、該スペーサ１５によって、部片１４、……が、該部片１４、……の外側に配した繰出し円筒部１１の内周面に弾性的に接触している状態を保持するようになっている。
【００１１】
スペーサ１５は、部片１４の繰出し円筒部１１の内周面に対する弾性的な接触状態を保持するためのもの、すなわち、部片１４の経時手機な変化による前記内周面からの離脱を防ぐためのもので、この意味では、該スペーサ１５は必ずしも、ゴムなどの弾性リングで構成する必要はないが、弾性リングで構成することにより主筒１３にその弾性を利用して取付けられる。
【００１２】
なお、供給リール４は、駆動歯車９部にボス部１０を介装するようにして一対の係止片１６、１６を備え、該係止片１６の装置基板３側に設けた係止爪１６ａが、装置基板３に前記第一支軸１２を中心とする円周に沿わせて連設した数の受止爪１７、……に係止して前記修正塗膜転写テープａの繰出し方向にのみ回動するようにしてある。
【００１３】
前記巻取りリール５は、前記ケース１を構成する装置基板３に前記第一支軸１２と並設した第二支軸１８にボス部１９において回動自在に組付け、該ボス部１９を取り囲むようにして配した巻取り円筒部２０の外周に沿わせて前記駆動歯車９にかみ合い、駆動歯車９より小形な従動歯車２１を設けて構成したものである。
【００１４】
なお、４ａ、５ａは補強突条を示す、各部材はスペーサ１５を除いて合成樹脂を素材とする。スペーサ１５はゴム製であるが樹脂製であっても良い。
【００１５】
図示２２は装置基板３に相対して配し、該装置基板３と図示省略したスペーサ杆で組合わせた区画板を示す。
【００１６】
しかして、塗膜転写ヘッド８により修正塗膜転写テープａを押し付けながら、ケース１を該テープａの長手方向に沿って移動させると、該テープａの塗膜が消去個所上に塗着され、消去操作が行われる。
【００１７】
そして、ケース１の移動に伴って修正塗膜転写テープａに加わるテンションが供給リール４の繰出し円筒部１１に回転トルクとして作用し、繰出し円筒部１１はスペーサ１５に押圧されて定位置（円筒部１１の内周面との接触状態位置）を維持した部片１４、……の接触抵抗により駆動歯車９ととも回動し、供給リール４は新たな修正塗膜転写テープａを繰り出すことになる。
【００１８】
また、駆動歯車９にかみ合った従動歯車２１は駆動歯車９に伴って回動し、従動歯車２１とともに巻取りリール５を構成する巻取り円筒部２０は回動し、塗膜がはぎ取られた使用済みの修正塗膜転写テープ部は該巻取り円筒部２０に自動的に巻き取られる。
【００１９】
実施例においては、字消し具はこのように用いるものであるが、使用に伴って、供給リール４側の転写テープａの巻回状態の外径が小さく繰出し速度が遅くなるに反し、巻回状態の外径が大きくなる巻取りリール５側は巻取り速度が速くなることになる（これは、歯車９、２１の大きさの関係によることは勿論である）。
【００２０】
このため、テンションが作用して転写テープａが切断してしまうおそれがあり、前記繰出し速度と巻取り速度を同期させる必要が生じることになる。
【００２１】
実施例のものは、両速度の同期が崩れて供給リール４側すなわち繰出し円筒部１１に作用する回動トルクが大きくなると、この回転トルクが、部片１４の繰出し円筒部１１に対する接触抵抗に打ち勝って繰出し円筒部１１がボス部１０に対して滑り回動し（ボス部１０に、すなわち駆動歯車９に回転トルクを作用させなくなり）、回転トルクが小さくなり、回転トルクの作用より接触抵抗の方が強くなると、前記の滑り回動は中断し、駆動歯車およびこれにかみ合う従動歯車は回動して繰出し巻取りの両速度は同期して修正塗膜転写テープａの移動が円滑に行われるのである。
【００２２】
【発明の効果】
本発明は前記の通りの構成であるから、スペーサによって部片の繰出し円筒部の内周面に対する接触状態を確実に縦持させ、かつ、部片と前記内周面は素材である硬い樹脂同士が接触するものであるから、修正塗膜転写テープのテンションが働いて、必要以上に大きな回転トルクが繰出し円筒部に作用した際、該回転トルクの作用は該繰出し円筒部に対する部片の接触抵抗より容易に打ち勝って回動し、従って、巻取り速度に容易に同期のできる供給リール装置を提供できる。

[Industrial application fields]
The present invention relates to a supply reel device for a correction coating film transfer tape of an eraser used for erasing or transferring a coating film of a correction coating film transfer tape onto a character and erasing the character.
[0002]
[Prior art]
The eraser is provided with a supply reel and a take-up reel for the correction coating film transfer tape in a rotatable manner in the case, a coating film transfer head projecting from the tip of the case, and the supply reel provided in the case The drive cylinder is pivotally supported on the first support shaft and is configured to engage the feed cylindrical portion so that it can rotate. The take-up reel rotates on the second support shaft provided on the case. A driven gear meshing with the drive gear is provided on an outer periphery of a winding cylindrical portion that is freely pivoted, and an intermediate portion of the coating film transfer tape between the feeding cylindrical portion and the winding cylindrical portion is disposed on the coating film transfer head. The film was pressed against the erasing surface with the coating film transfer head, while the coating film transfer tape was fed from the supply reel, the coating film transfer operation (erasing operation) was performed, and the film was fed from the supply reel. The modified coating film transfer tape has a gear device on the supply reel. It is adapted to be taken up by the take-up reel in conjunction with.
[0003]
However, with the use of the modified coating film transfer tape, the winding amount on the take-up reel side inevitably increases from the winding amount on the supply reel side, and the feeding speed on the supply reel side and the winding speed on the take-up reel side are increased. And the balance is lost (synchronization is lost), and the coating film cannot be transferred smoothly.
[0004]
For this reason, as disclosed in Japanese Patent Laid-Open No. 5-58097, the feeding cylindrical portion of the supply reel is fitted to the boss portion of the drive gear via the O-ring, and the inner surface of the feeding cylindrical portion is brought into contact with the O-ring, By this contact, the boss part (drive gear) and the feeding cylindrical part (supply reel) rotate integrally, and when the synchronism between the feeding and winding is broken, the feeding cylindrical part with respect to the boss part. A structure has been proposed in which the slidable rotation of the two speeds can be recovered.
[0005]
[Problems to be solved by the invention]
In the conventional example, since the rotation is transmitted to the cylindrical portion by the contact of the O-ring (made of elastomer) by the feeding cylindrical portion, the contact resistance due to the material of the O-ring is large, and therefore, the synchronization is restored. In some cases, the sliding rotation operation is not always performed smoothly.
[0006]
The present invention has been devised for the purpose of providing a supply reel device in which the feeding operation is reliably performed as compared with the conventional example, and the sliding rotation of the feeding cylindrical portion with respect to the boss portion is favorably performed.
[0007]
[Means for Solving the Problems]
A supply reel and a take-up reel for the correction coating film transfer tape are rotatably provided in a case having a coating film transfer head protruding at the tip, and the supply reel is freely rotatable on a first support shaft provided in the case. The take-up reel is pivotally supported by a second support shaft provided in the case, while the feed cylindrical portion is rotatably engaged with the boss portion of the drive gear pivotally supported by A driven gear meshing with the drive gear is provided along the outer periphery of the winding cylindrical portion, and the intermediate portion of the corrected coating film transfer tape between the feeding cylindrical portion and the winding cylindrical portion is the coating film transfer. In the eraser that is pressed against the erasing surface by the head, the main cylinder in which the boss portion of the drive gear is rotatably assembled to the first support shaft, and the outer circumference of the main cylinder are arranged in parallel. A plurality of pieces that elastically contact the inner peripheral surface of the feeding cylindrical portion, Between the main cylinder and a structure in which is fitted a ring-shaped spacer.
[0008]
【Example】
FIG. 1 shows an embodiment of a supply reel device for a modified coating film transfer tape in an eraser according to the present invention, FIG. 1 is a partially cutaway front view showing the case opened, and FIG. FIG.
[0009]
The eraser A according to the embodiment is fitted to the half member 1a and the other half member 1b, and the device substrate 3 is fitted to the window 2 provided on the half member 1b to form the case 1, and the case 1 In addition, each of the supply reel 4 and the take-up reel 5 for continuously winding the correction coating film transfer tape a fed from the supply reel 4 is supported on the apparatus substrate 3 and accommodated on the apparatus substrate 3. The tip of the support member 6 assembled with the base portion is led out from the opening tip of the cylindrical portion 7 through the cylindrical portion 7 having a square cross section disposed on the front side of the case 1, and the correction coating film is applied to the tip. A coating film transfer head 8 is provided to transfer and apply the corrected coating film layer of the transfer tape a to an erasing location (such as a paper surface), and the corrected coating film transfer tape a is used as an erasing location using the transfer head 8. Move the case 1 by an appropriate amount along the longitudinal direction of the transfer tape a in the pressed state. Then, the transfer tape a is unwound from the supply reel 4, and the used transfer tape portion from which the correction coating film has been peeled is wound around the take-up reel 5 interlocked with the supply reel 4 by meshing with a gear (described later). Then, a correction coating film is applied on the erasure point, and a so-called erase operation (transfer operation) is performed.
[0010]
The supply reel 4 is configured to engage with a boss portion 10 of a driving gear 9 from a peripheral side of the boss portion 10 so that a cylindrical portion 11 is rotatably engaged. The boss portion 10 is attached to the device substrate 3. The main cylinder 13 is composed of a main cylinder 13 rotatably attached to the first support shaft 12 provided, and a plurality of pieces 14 arranged in parallel along the outer periphery of the main cylinder 13. And a piece 14,... Are inserted into the main cylinder 13 and a spacer 15 made of an elastic ring is interposed between the pieces 14,. The state which is elastically contacting the inner peripheral surface of the feeding cylindrical part 11 arranged on the outside is maintained.
[0011]
The spacer 15 is for maintaining an elastic contact state of the piece 14 with respect to the inner peripheral surface of the feeding cylindrical portion 11, that is, for preventing separation of the piece 14 from the inner peripheral surface due to a change with time. In this sense, the spacer 15 does not necessarily have to be formed of an elastic ring such as rubber. However, the spacer 15 is attached to the main cylinder 13 by using the elastic ring.
[0012]
The supply reel 4 includes a pair of locking pieces 16, 16 so that the boss portion 10 is interposed in the drive gear 9, and a locking claw 16 a provided on the device substrate 3 side of the locking piece 16. However, it is engaged with the number of receiving claws 17,... Continuously provided along the circumference centering on the first support shaft 12 on the apparatus substrate 3, and in the feeding direction of the corrected coating film transfer tape a. Only to rotate.
[0013]
The take-up reel 5 is rotatably attached to a second support shaft 18 provided in parallel with the first support shaft 12 on a device substrate 3 constituting the case 1 at a boss portion 19 so as to surround the boss portion 19. The drive gear 9 is meshed with the outer periphery of the winding cylindrical portion 20 arranged as described above, and a driven gear 21 smaller than the drive gear 9 is provided.
[0014]
Reference numerals 4a and 5a denote reinforcing protrusions, and each member is made of synthetic resin except for the spacer 15. The spacer 15 is made of rubber, but may be made of resin.
[0015]
FIG. 22 shows a partition plate which is arranged relative to the device substrate 3 and is combined with the device substrate 3 by a spacer rod not shown.
[0016]
Thus, when the case 1 is moved along the longitudinal direction of the tape a while pressing the corrected coating film transfer tape a by the coating film transfer head 8, the coating film of the tape a is applied on the erasure point, An erase operation is performed.
[0017]
Then, the tension applied to the correction coating film transfer tape a as the case 1 moves acts as a rotational torque on the feeding cylindrical portion 11 of the supply reel 4, and the feeding cylindrical portion 11 is pressed by the spacer 15 to be in a fixed position (cylindrical portion). 11 is rotated with the drive gear 9 by the contact resistance of the pieces 14 that maintain the contact state position with the inner peripheral surface 11), and the supply reel 4 feeds out a new corrected coating film transfer tape a. .
[0018]
Further, the driven gear 21 engaged with the drive gear 9 is rotated along with the drive gear 9, and the winding cylindrical portion 20 constituting the winding reel 5 is rotated together with the driven gear 21, so that the coating film is peeled off. The used corrected coating film transfer tape portion is automatically wound around the winding cylindrical portion 20.
[0019]
In the embodiment, the eraser is used in this way, but with use, the outer diameter of the winding state of the transfer tape a on the supply reel 4 side is small and the feeding speed is slow. The take-up reel 5 side in which the outer diameter of the state becomes large has a high take-up speed (this is of course due to the relationship between the sizes of the gears 9 and 21).
[0020]
For this reason, there is a possibility that the transfer tape a is cut due to the tension, and it becomes necessary to synchronize the feeding speed and the winding speed.
[0021]
In the embodiment, when both speeds are out of sync and the rotational torque acting on the supply reel 4 side, that is, the feeding cylindrical portion 11 is increased, this rotational torque overcomes the contact resistance of the piece 14 with respect to the feeding cylindrical portion 11. Thus, the feeding cylindrical portion 11 slides and rotates with respect to the boss portion 10 (rotation torque is not applied to the boss portion 10, that is, the drive gear 9), and the rotation torque is reduced. When the rotation becomes stronger, the above-mentioned sliding rotation is interrupted, and the drive gear and the driven gear meshing therewith are rotated so that both the speeds of the take-up and winding are synchronized and the correction coating film transfer tape a is moved smoothly. is there.
[0022]
【The invention's effect】
Since the present invention is configured as described above, the spacer reliably holds the contact state with respect to the inner peripheral surface of the feeding cylindrical portion of the piece, and the piece and the inner peripheral surface are made of hard resin. Therefore, when the tension of the corrected coating film transfer tape is applied and an excessively large rotational torque acts on the feeding cylindrical portion, the rotational torque acts on the contact resistance of the piece to the feeding cylindrical portion. It is possible to provide a supply reel device that can be overcome and rotated more easily, and thus can be easily synchronized with the winding speed.
