【産業上の利用分野】[Industrial applications]

本考案は、例えばタグ用紙等の単票用紙に情報を印字するプリンタに関する。 The present invention relates to a printer that prints information on cut-sheet paper such as tag paper.

【0002】[0002]

【従来の技術】[Prior Art]

従来、タグ用紙に情報を印字するプリンタは、例えば図4に示すように構成さ れている。同図において、1はホッパ、2はホッパ1内に設けられた用紙受けで あり、この用紙受け2の上には多数枚のタグ用紙3が上下に積み重なって載置さ れている。これらのタグ用紙3は、図5に示すように、台紙4と、この台紙4上 に剥離可能に貼着された印字用紙5とからなり、図6に示す如くタグ用紙3の前 端部と後端部が重なり合うように台紙3を内側に折り曲げて用紙受け2の上に載 置されている。 Conventionally, a printer that prints information on tag paper is configured, for example, as shown in FIG. In the figure, 1 is a hopper, 2 is a paper receiver provided in the hopper 1, and a large number of tag papers 3 are vertically stacked on the paper receiver 2. As shown in FIG. 5, these tag papers 3 are composed of a mount paper 4 and a print paper 5 which is releasably adhered onto the mount paper 4, and as shown in FIG. The backing sheet 3 is folded inward so that the rear ends thereof are overlapped and placed on the sheet receiver 2.

【0003】 なお、ホッパ1内には圧縮スプリング6が用紙受け2の下方に配設されており 、この圧縮スプリング6のばね力により用紙受け2は上方に押し上げられている 。A compression spring 6 is arranged in the hopper 1 below the sheet receiver 2, and the sheet spring 2 is pushed upward by the spring force of the compression spring 6.

【0004】 一方、ホッパ1の上方には、タグ用紙3をホッパ1から送り出す用紙送出し機 構7が設けられている。この用紙送出し機構7は、ホッパ1内に積み重なって収 容された多数枚のタグ用紙3のうち最も上方に位置するタグ用紙3と接触する無 端状のベルト8と、このベルト8を矢印方向に旋回駆動する駆動ローラ9および 従動ローラ10とを備えており、ベルト8の旋回力でタグ用紙3を上層側のタグ 用紙3から順に送り出すように構成されている。On the other hand, above the hopper 1, a paper feeding mechanism 7 for feeding the tag paper 3 from the hopper 1 is provided. The sheet feeding mechanism 7 is an endless belt 8 that comes into contact with the tag sheet 3 located at the uppermost position among a large number of tag sheets 3 that are stacked and accommodated in the hopper 1, and this belt 8 is indicated by an arrow. It is provided with a driving roller 9 and a driven roller 10 which are driven to rotate in a direction, and is configured to sequentially feed the tag paper 3 from the tag paper 3 on the upper layer side by the turning force of the belt 8.

【0005】 また、11は上記用紙送出し機構7によりホッパ1から送り出されたタグ用紙 3を印字部19に案内する用紙ガイドであり、この用紙ガイド11の途中には、 タグ用紙3を印字部19に搬送する搬送機構12が配設されている。この搬送機 構12は、第1の搬送ローラ13と、この第1の搬送ローラ13に回転自在に周 接する第2の搬送ローラ14と、上記第1の搬送ローラ13をプーリ16,ベル ト17,プーリ18を介して駆動する駆動モータ15とを備えており、上記第1 の搬送ローラ13と第2の搬送ローラ14とでタグ用紙3を印字部19に搬送す るようになっている。Further, 11 is a paper guide for guiding the tag paper 3 sent from the hopper 1 by the paper sending mechanism 7 to the printing unit 19, and in the middle of the paper guide 11, the tag paper 3 is printed in the printing unit 19. A transport mechanism 12 for transporting to 19 is provided. This transport mechanism 12 includes a first transport roller 13, a second transport roller 14 rotatably circumscribing the first transport roller 13, the first transport roller 13 connected to a pulley 16 and a belt 17. , And a drive motor 15 driven via a pulley 18, and the first transport roller 13 and the second transport roller 14 transport the tag paper 3 to the printing unit 19.

【0006】 なお、第2の搬送ローラ14は第1の搬送ローラ13に対して接離自在となっ ており、第1の搬送ローラ13との間にタグ用紙3が搬送されると、タグ用紙3 の紙厚に応じて第1の搬送ローラ13から離間する方向に変位するようになって いる。It should be noted that the second transport roller 14 is movable in and out of contact with the first transport roller 13, and when the tag paper 3 is transported between the first transport roller 13 and the first transport roller 13, According to the paper thickness of No. 3, it is displaced in the direction away from the first conveying roller 13.

【0007】 上記印字部19は、タグ用紙3の上面側を印字する第1の印字機構20と、タ グ用紙3の下面側を印字する第2の印字機構21とを備えており、これらの印字 機構20,21でタグ用紙3の印字用紙4に情報を印字するようになっている。 なお、上記印字機構20,21は、それぞれプラテン22とサーマルヘッド23 との間にインクリボン24を介在させて構成されている。The printing unit 19 includes a first printing mechanism 20 that prints on the upper surface side of the tag paper 3 and a second printing mechanism 21 that prints on the lower surface side of the tag paper 3. Information is printed on the printing paper 4 of the tag paper 3 by the printing mechanisms 20 and 21. The printing mechanisms 20 and 21 are configured by interposing an ink ribbon 24 between the platen 22 and the thermal head 23, respectively.

【考案が解決しようとする課題】[Problems to be solved by the device]

ところで、このようなプリンタでは、用紙送出し機構7を駆動した際にタグ用 紙3が2枚同時にホッパ1から送り出されることがあった。しかしながら、従来 ではタグ用紙3が2枚同時にホッパ1から送り出されたことを検出することがで きないため、用紙ガイド11内で紙詰まりが発生したり、あるいはサーマルヘッ ド23の故障原因となるなどの問題があった。 By the way, in such a printer, when the paper feeding mechanism 7 is driven, two pieces of tag paper 3 may be fed from the hopper 1 at the same time. However, conventionally, it is not possible to detect that two pieces of tag paper 3 have been sent out from the hopper 1 at the same time, so that paper jam may occur in the paper guide 11 or the thermal head 23 may malfunction. There was a problem.

【0009】 また、タグ用紙3が2枚同時に送り出され、印字部19に搬送された場合には 、タグ用紙3を片面しか印字することができないため、用紙の無駄となる問題も あった。Further, when two pieces of the tag paper 3 are sent out at the same time and are conveyed to the printing unit 19, only one side of the tag paper 3 can be printed, and there is a problem that the paper is wasted.

【0010】 本考案は上記のような問題点に鑑みてなされたもので、その目的はタグ用紙等 の単票用紙が複数枚同時に送り出されたことを検出することのできるプリンタを 提供することにある。The present invention has been made in view of the above problems, and an object thereof is to provide a printer capable of detecting that a plurality of single-cut sheets such as tag sheets have been sent out at the same time. is there.

【実施例】【Example】

以下、本考案の一実施例を図1および図2を参照して説明する。なお、図4〜 図6に示したものと同一部分には同一符号を付し、その部分の説明は省略する。 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The same parts as those shown in FIGS. 4 to 6 are designated by the same reference numerals, and the description of those parts will be omitted.

【0014】 図1において、25は第2の搬送ローラ14を支持するローラ軸であり、この ローラ軸25には変位量増幅伝達部材26の一端が連結されている。この変位量 増幅伝達部材26は軸27を支点として上下方向に回動自在となっており、第2 の搬送ローラ14がタグ用紙3の紙厚に応じて第1の搬送ローラ13から離間す る方向に変位すると、その変位量に応じて図中時計方向に回動するようになって いる。そして、変位量増幅伝達部材26が軸27を支点として図中時計方向に回 動すると、変位量増幅伝達部材26の他端に設けられた遮光部材28が光検出器 29の検出光路から外れる方向に移動するようになっている。In FIG. 1, reference numeral 25 denotes a roller shaft that supports the second transport roller 14, and one end of a displacement amount amplification transmission member 26 is connected to the roller shaft 25. The displacement amplification transmission member 26 is rotatable in the vertical direction about a shaft 27 as a fulcrum, and the second conveying roller 14 is separated from the first conveying roller 13 according to the thickness of the tag sheet 3. When it is displaced in the direction, it rotates clockwise in the figure according to the amount of displacement. When the displacement amplification transmission member 26 rotates clockwise in the figure with the shaft 27 as a fulcrum, the light shielding member 28 provided at the other end of the displacement amplification transmission member 26 moves away from the detection optical path of the photodetector 29. To move to.

【0015】 なお、変位量増幅伝達部材26の回動支点である軸27は、第2の搬送ローラ 14の変位を遮光部材28が設けられた変位量増幅伝達部材26の他端に増幅し て伝えるために変位量増幅伝達部材26の一端寄りに設けられている。It should be noted that the shaft 27, which is the fulcrum of rotation of the displacement amplification transmission member 26, amplifies the displacement of the second transport roller 14 to the other end of the displacement amplification transmission member 26 provided with the light shielding member 28. It is provided near one end of the displacement amplification transmission member 26 for transmission.

【0016】 上記のように構成される本実施例では、第1の搬送ローラ13と第2の搬送ロ ーラ14との間に2枚のタグ用紙3が重なり合って供給されると、図2に示す如 く変位量増幅伝達部材26の他端に設けられた遮光部材28が光検出器29の検 出光路から外れた位置に移動する。そして、遮光部材28が光検出器29の検出 光路から外れた位置に移動すると、光検出器29がオフ状態からオン状態に切り 替わるので、ホッパ1からタグ用紙3が2枚同時に送り出されたことを光検出器 29で検出することができる。したがって、本実施例では光検出器29がオフ状 態からオン状態に切り替わったときに搬送系の駆動を停止するようにすれば、タ グ用紙3の紙詰まりやサーマルヘッド23の損傷等を防止することが可能となる 。In the present embodiment configured as described above, when the two tag sheets 3 are overlapped and supplied between the first transport roller 13 and the second transport roller 14, when the tag paper 3 is fed as shown in FIG. The light shielding member 28 provided on the other end of the displacement amplification transmitting member 26 moves to a position deviated from the detection optical path of the photodetector 29 as shown in FIG. Then, when the light blocking member 28 moves to a position deviated from the detection optical path of the photodetector 29, the photodetector 29 is switched from the off state to the on state, so that two pieces of the tag paper 3 are fed from the hopper 1 at the same time. Can be detected by the photodetector 29. Therefore, in this embodiment, when the photodetector 29 is switched from the off state to the on state, the driving of the transport system is stopped to prevent the jam of the tag sheet 3 and the damage of the thermal head 23. It becomes possible to do.

【0017】 なお、上述した一実施例では第2の搬送ローラ14を支持するローラ軸25に 変位量増幅伝達部材26の一端を連結したが、ローラ軸25に変位量増幅伝達部 材26の一端を必ずしも連結する必要はなく、変位量増幅伝達部材26の一端を ローラ軸25に当接させておいても良い。In the above-described embodiment, one end of the displacement amount amplification transmission member 26 is connected to the roller shaft 25 supporting the second conveying roller 14, but one end of the displacement amount amplification transmission member 26 is connected to the roller shaft 25. Need not necessarily be connected, and one end of the displacement amplification transmission member 26 may be brought into contact with the roller shaft 25.

【0018】 また、上述した一実施例では変位量増幅伝達部材26の一端に第2の搬送ロー ラ14を取り付けたが、たとえば図3に示すように変位量増幅伝達部材26の一 端に回動支点である軸27を設け、変位量増幅伝達部材26の一端と他端との間 に第2の搬送ローラ14を取り付けても同様の効果が得られる。Further, in the above-described embodiment, the second conveyance roller 14 is attached to one end of the displacement amount amplification transmission member 26. However, as shown in FIG. The same effect can be obtained by providing the shaft 27, which is a dynamic fulcrum, and attaching the second conveying roller 14 between one end and the other end of the displacement amplification transmitting member 26.

【0019】 さらに、上述した一実施例ではタグ用紙3に情報を印字するプリンタについて 説明したが、ホッパ1内に収容される用紙はタグ用紙3に限られるものではなく 、タグ用紙以外の単票用紙でも適用可能であることはいうまでもない。Furthermore, in the above-described embodiment, the printer that prints information on the tag paper 3 has been described, but the paper accommodated in the hopper 1 is not limited to the tag paper 3, and single sheets other than tag paper can be used. Needless to say, it can be applied to paper.

【0020】 また、用紙送出し機構8の構成は上述した実施例に限定されるものではなく、 例えばベルト8の代わりローラを用いた用紙送出し機構でも良い。Further, the configuration of the sheet delivery mechanism 8 is not limited to the above-described embodiment, and for example, a sheet delivery mechanism using rollers instead of the belt 8 may be used.
