A paper cover frame 40 that rotates about the center, and an opening / closing lid 50 that is attached to the paper cover frame 40 and covers the hollow portion 23 are provided. The support hole 32 has an elliptical shape with the major axis in the horizontal direction, and the rotation shaft 33 is formed to be movable in the horizontal direction.

用紙カバーフレーム４０の先端側には、プラテンローラ４１が設けられており、開閉機構３０を閉じた状態でサーマルヘッド２５に押圧されることとなる。さらに用紙カバーフレーム４０には前述した挿入部材２６の被係止部２９を係止するためのピン（係止部）４２が設けられている。また、用紙カバーフレーム４０の中間部には、本体部２２に当接する当接部材４３が設けられており、バネ部材４４により、用紙カバーフレーム４０が開く方向に付勢されている。   A platen roller 41 is provided on the leading end side of the paper cover frame 40 and is pressed against the thermal head 25 with the opening / closing mechanism 30 closed. Further, the paper cover frame 40 is provided with a pin (locking portion) 42 for locking the locked portion 29 of the insertion member 26 described above. An abutting member 43 that abuts the main body 22 is provided at an intermediate portion of the paper cover frame 40, and is urged by the spring member 44 in the direction in which the paper cover frame 40 is opened.

開閉蓋５０は蓋体５１を備え、この蓋体５１の基端側が用紙カバーフレーム４０に対し揺動軸５１ａを介して上下方向に揺動可能に取り付けられている。また、蓋体５１の筐体本体２０の一方側に相当する先端側には、開閉ボタン５２が取り付けられている。図２に示すように、開閉ボタン５２の下面は開口されており、挿入部材２６が挿入可能な凹部５３が設けられている。   The open / close lid 50 includes a lid 51, and the base end side of the lid 51 is attached to the paper cover frame 40 so as to be swingable in the vertical direction via a swing shaft 51 a. In addition, an open / close button 52 is attached to the distal end side corresponding to one side of the casing body 20 of the lid 51. As shown in FIG. 2, the lower surface of the open / close button 52 is opened, and a recess 53 into which the insertion member 26 can be inserted is provided.

凹部５３には、挿入部材２６の先端２８に設けられた傾斜面２８ａが摺動可能に形成された傾斜面５３ａが設けられ、この傾斜面５３ａの上側にはさらに傾斜角度の大きい傾斜面５３ｂが連設されている。これにより、凹部５３及び挿入部材２６の先端部２８は、開閉ボタン５２を押し下げることにより、先端部２８を左側に移動させることができ、引張バネ２７ａによる付勢力に抗してピン４２と被係止部２９との係止を解除することができる。   The recess 53 is provided with an inclined surface 53a in which an inclined surface 28a provided at the distal end 28 of the insertion member 26 is slidable, and an inclined surface 53b having a larger inclination angle is provided above the inclined surface 53a. It is connected continuously. Accordingly, the recess 53 and the distal end portion 28 of the insertion member 26 can move the distal end portion 28 to the left side by depressing the open / close button 52, and the pin 42 is engaged with the pin 42 against the urging force of the tension spring 27a. The locking with the stop portion 29 can be released.

このように構成されたサーマルプリンタ１０では、次のようにして感熱紙Ｐを交換する。すなわち、開閉機構３０の開閉ボタン５２を押し下げることにより、凹部５３の傾斜面５３ａが挿入部材２６の傾斜面２８ａに当接し、挿入部材２６の先端２８を図中左側へ移動させる。これにより、図３に示すように、ピン４２と被係止部２９との係止が解除される。   In the thermal printer 10 configured as described above, the thermal paper P is replaced as follows. That is, by depressing the open / close button 52 of the open / close mechanism 30, the inclined surface 53a of the recess 53 comes into contact with the inclined surface 28a of the insertion member 26, and the tip 28 of the insertion member 26 is moved to the left in the drawing. Thereby, as shown in FIG. 3, the locking of the pin 42 and the locked portion 29 is released.

この係止が解除されても、入部材２６の傾斜面２８ａは凹部５３の傾斜面５３ａを右側へ押圧することになるため、用紙カバーフレーム４０は、全体的に右側へ付勢されることとなる。一方、支持孔３２が楕円形状であるため、用紙カバーフレーム４０の回動軸３３が右方向に移動する。また、樹脂材製のベース部２１が撓むことで、サーマルヘッド２５とプラテンローラ４１とが離間し、用紙カバーフレーム４０を開く際にプラテンローラ４１が本体部２２に干渉することはない。   Even if this locking is released, the inclined surface 28a of the insertion member 26 presses the inclined surface 53a of the concave portion 53 to the right side, so that the paper cover frame 40 is generally biased to the right side. Become. On the other hand, since the support hole 32 has an elliptical shape, the rotation shaft 33 of the paper cover frame 40 moves to the right. Further, since the resin base portion 21 is bent, the thermal head 25 and the platen roller 41 are separated from each other, and the platen roller 41 does not interfere with the main body portion 22 when the paper cover frame 40 is opened.

なお、用紙カバーフレーム４０の当接部材４３が本体部２２に押し付けられているので、用紙カバーフレーム４０は自動的に開くこととなる。   Since the contact member 43 of the paper cover frame 40 is pressed against the main body 22, the paper cover frame 40 is automatically opened.

感熱紙Ｐの交換を行った後、用紙カバーフレーム４０を閉じていくと、最初に当接部材４３が本体部２２に当接し、バネ部材４４をゆっくりと引き伸ばしてゆくため、用紙カバーフレーム４０はゆっくりと閉じることとなる。   When the paper cover frame 40 is closed after the thermal paper P is replaced, the contact member 43 first comes into contact with the main body 22 and the spring member 44 is slowly stretched. It will close slowly.

用紙カバーフレーム４０を押し込んでゆくと、ピン４２が挿入部材２６の先端２８の傾斜面２８ａに当接し筐体本体２０の一方側に挿入部材２６を移動させる。そして、ピン４２と被係止部２９とが係合し、プラテンローラ４１がサーマルヘッド２５に当接する。 When the paper cover frame 40 is pushed in, the pin 42 comes into contact with the inclined surface 28 a of the distal end 28 of the insertion member 26 and moves the insertion member 26 to one side of the housing body 20 . Then, the pin 42 and the locked portion 29 are engaged, and the platen roller 41 is brought into contact with the thermal head 25.

上述したように、本実施の形態に係るサーマルプリンタ１０によれば、感熱紙Ｐを交換する際に、開閉ボタン５２を押し下げるだけの簡単な操作で開閉蓋５０を開閉することができるとともに、プラテンローラ４１を他の部材に干渉させることを防止できる。   As described above, according to the thermal printer 10 according to the present embodiment, when the thermal paper P is replaced, the open / close lid 50 can be opened and closed with a simple operation by simply pressing the open / close button 52, and the platen It is possible to prevent the roller 41 from interfering with other members.

なお、本発明は前記実施の形態に限定されるものではない。例えば、図５に示すように、挿入部材２６について先端２８をさらに強く右側へ付勢するために、引張バネ（付勢部材）２７ｂを付加するようにしてもよい。この他、本発明の要旨を逸脱しない範囲で種々変形実施可能であるのは勿論である。   The present invention is not limited to the above embodiment. For example, as shown in FIG. 5, a tension spring (biasing member) 27 b may be added to urge the insertion member 26 more strongly toward the right side of the distal end 28. Of course, various modifications can be made without departing from the scope of the present invention.
