そして、 図示しないパソコン等から U S B端子や赤外線端子を介し て印字指令及ぴ画像データ(印刷データ)をプリンタ装置 1に送ると、 駆動モータ 2 2が回転駆動し、 ピックアップローラ 1 1 とプラテン口 ーラ 9は同時に回転し始める。ピックアップローラ 1 1 の回転により、 前記積層された用紙 4のうち最下層の用紙 4の先端 4 aが、 分離プロ ック 1 2に衝突して最下層の用紙 4のみが分離されて、 分離プロック 1 2の下面とガイ ド板 1 7 と間に搬送さる。 次いで、 プラテンローラ 9とペーパーガイ ド 1 0との間に挟持された用紙 4は、 回転するプラ テンローラ 9とペーパーガイ ド 1 0にて挟持搬送されてサーマルへッ ド 8方向に移動し、 用紙 4の表面に印字された後、 固定カバー体 3 と 前記分離プロック 1 2の背面との隙間 2 0からプリ ンタ装置 1外に排 紙される。 When a print command and image data (print data) are sent from a personal computer or the like (not shown) to the printer device 1 via the USB terminal or the infrared terminal, the drive motor 22 is driven to rotate, and the pickup roller 11 and the platen port are rotated. La 9 starts rotating at the same time. By the rotation of the pickup roller 11, the leading end 4a of the lowermost layer 4 of the stacked sheets 4 collides with the separation block 12 and only the lowermost layer 4 is separated, so that the separation block is formed. It is transported between the lower surface of 12 and the guide plate 17. Next, the paper 4 nipped between the platen roller 9 and the paper guide 10 is nipped and conveyed by the rotating platen roller 9 and the paper guide 10 and moves in the direction of the thermal head 8, and After being printed on the surface of 4, the paper is discharged out of the printer device 1 through a gap 20 between the fixed cover body 3 and the back surface of the separation block 12.
次に、 紙ジャムが発生した場合に、 前記サーマルヘッ ド 8とぺーパ 一ガイ ド 1 0とを蓋体 1 3の開き動作に連動してリ リースする動作に ついて説明する。 Next, an operation of releasing the thermal head 8 and the paper guide 10 in conjunction with the opening operation of the lid 13 when a paper jam occurs will be described.
まず、 蓋体 1 3を後退移動させて蓋体 1 3の回動支点 1 4 a (第 5 図 (b ) ) をロック位置 Aからロック解除位置 Bへ移動させる。 つま り、 蓋体 1 3を第 8図 ( c ) に示す閉止位置から第 8図 (b ) に示す 後退位置へ後退させる。 すると、 蓋体 1 3のロック片 2 5は一対の規
制ブロック 2 9、 3 0の間に嵌まっているので、 作動部材 2 8が付勢 手段 1 6、 1 9の付勢力に抗して強制的に後退される。 この時、 樹脂 パネ体 3 2の付勢力にも抗して移動されるが、 付勢手段 1 6、 1 9の 付勢力の方が大きい。 First, the lid 13 is moved backward to move the pivot 14a (FIG. 5 (b)) of the lid 13 from the lock position A to the unlock position B. That is, the lid 13 is retracted from the closed position shown in FIG. 8 (c) to the retracted position shown in FIG. 8 (b). Then, the lock pieces 25 of the lid 13 are Since it is fitted between the control blocks 29 and 30, the operating member 28 is forcibly retracted against the urging force of the urging means 16 and 19. At this time, it is moved against the urging force of the resin panel body 32, but the urging force of the urging means 16 and 19 is larger.
このように作動部材 2 8を後退位置まで後退させると、 第 8図 (b ) に示すように縦案内溝 2 6の下方退避領域まで退避していた樹脂パネ 体 3 2の上向き先端部 3 2 aが、 第 8図 ( a ) に示すように弾性力に より規制ブロック 2 9、 3 0の間に下方から係合し、 これにより作動 部材 2 8の後退位置が保持される。 When the operating member 28 is retracted to the retracted position in this manner, as shown in FIG. 8 (b), the resin panel body 32 which has been retracted to the lower evacuation area of the vertical guide groove 26 has an upward end 3 2 As shown in FIG. 8 (a), a is engaged from below by the elastic force between the restriction blocks 29, 30 so that the retracted position of the operating member 28 is maintained.
また、 前記作動部材 2 8の後退移動に伴って、 作動部材 2 8に連結 されている連動リンク体 3 3は回転軸 9 aを中心に反時計回りに回動 する。 すると、 連動リンク体 3 3の第 1カム体 3 6は付勢手段 1 6の 付勢力に抗してペーパーガイ ド 1 0を前方へ押して、 第 8図 (b ) に 示すように、 ペーパーガイ ド 1 0をプラテンローラ 9の外周面から離 す。 それと同時に第 2カム体 3 7が付勢手段 1 9の付勢力に抗してサ 一マルへッ ド 8の下面を上向きに押し上げ、 サーマルへッ ド 8の発熱 体部 8 aがプラテンローラ 9の外周面から離れるのである。 この状態 が離間位置である。 この状態で蓋体 1 3を上方に回動させて本体ケー ス 2の上面を開放すれば、 プラテンローラ 9の外周に巻き付いている 用紙 4を軽い力でプラテン装置 1の外に引き出すことができる。なお、 , このとき用紙パッケージ 5を交換することもできる。 Further, with the retreating movement of the operating member 28, the interlocking link body 33 connected to the operating member 28 rotates counterclockwise about the rotation shaft 9a.
