列印組件，其中定位機構可確實定位待列印物件，而列印 組件可進行環狀式列印，使得當複數個待列印物件置入供 其容置所設之容置空間後，本案之環狀式列印裝置即可環 • 狀式地依序列印該待列印物件。此外，本案之環狀式列印 裝置係可應用於各式各樣的待列印物件，如第二圖所示， 其係為本案之環狀式列印裝置之應用示意圖，由於本案之 環狀式列印裝置係可應用於具有曲面之物件，因此可將本 案之環狀式列印裝置做為指甲彩繪機1來列印彩繪人體或 指曱等等，當然也可應用於其他的曲面物件，如棒型物件 等等。 以下，將以人體之指甲作為待列印物件為例來更進一 • 步清楚說明本案之技術。請參閱第三圖並同時配合參閱第 四圖（a)與第四圖（b)，該第三圖係為本案之環狀式列印裝置 内部結構之正面視圖，而第四圖（a)與第四圖（b)係為本案之 環狀式列印裝置之定位機構之剖面及作動示意圖。如圖所 示，本案之環狀式列印裝置主要包含一列印組件10以及 一定位機構20。其中列印組件10係由一驅動組件30所控 制，且驅動組件30包含馬達31以及齒輪組32，馬達31 的種類並無限定，且齒輪組的大小及個數亦無限定，其係 可根據列印裝置之實際需要做設計及更改。 1310733 本案之環狀式列印裝置之列印組件ίο至少包含一列 印材料匣11以及一環型導軌12,其中列印材料匣11内放 置的材料並無限定，目ilj的技術以嘴墨式的列印材料為 佳，該列印材料匣11設於環型導執12上，並可於環型導 軌12上來回移動，而環型導軌12則是環繞於定位機構20 之外圍，且環型導執12上設有複數個固定元件121，以讓 環型導軌12得以確實固定，於實施例中，固定元件121 可以軸承為之，且可平均分佈於環型導軌12上，如此更 可進一步加強環型導軌的定位，而不致發生晃動的問題。 當列印組件10受到驅動組件30驅動而開始於環型導軌12 上進行列印時，列印組件1〇便可順著環型導執12依序對 放置於定位機構20之容置空間21内的手指100之指甲101 進行列印。此外，列印組件1 〇還包含一感測元件13，其 係可依實際需要感測手指100之大小、形狀或範圍等等。 於本實施例中，感測元件13係以光學反射元件為之，採 用CCD光學原理，當手指100放入容置空間21後，感測 元件13可先於手指100之指曱101上進行掃描，只要掃 描出指曱101最兩侧邊的位置，便可得出指曱101之中心 點，如此一來，當進行列印的時候，就可僅於指甲101之 大小範圍内進行，不但確保列印的準確性，又可防止浪費 列印材料以致於製造污染。 本案之環狀式列印裝置之定位機構20包含至少一容 置空間21、滑座22、支桿23以及定位桿24，其中容置空 間21可容置手指100與指曱101，且尾端係設有一開口 11 1310733 211，而滑座22則是設於容置空間21之尾端，且更包含 有一彈性元件221，該滑座22之底部與支桿23連接，而 支桿23的另一端則連接於定位桿24。不難想像的，當手 指100放入容置空間21後，可將定位桿24向前推進，使 得支桿23受到連帶的作用向上推頂滑座22，此時，滑座 22内的彈性元件221便會向上抵頂手指100，進而使指甲 101凸出於該容置空間21之開口 211，以準確定位該手指 100及其指曱101於該容置空間21内，使得列印組件10 進行列印的時候，僅會對凸出於該開口 211的指甲101部 位進行列印。為了更加確保手指1〇〇不會在容置空間21 内部產生晃動而影響列印的進行，該滑座22之上方更可 加設有夾持定位元件25，以本實施例而言，係可設計有大 致上呈V字型的夾持定位元件25,當手指100底部受到滑 座22及其彈性元件221推擠時，還可利用V字型的夾持 定位元件25使得手指100之底部同時受到左、右以及下 方的力量來支撐，如此一來，便可使得手指1〇〇於容置空 間21中的定位更確實。當然，定位機構20可於背面處設 有底盤26，使得容置空間21之底部有個限度，而不致使 手指100放入容置空間21後，陷入容置空間21中，簡單 來說，當手指1〇〇放入容置空間21後，只要手指100的 前端碰觸到底盤26時，就可清楚的知道，手指100已經 放在正確的位置上。同時底盤26可固定彈性元件22、支 桿23以及定位桿24的位置，使得定位機構20成為獨立 之組件。 12 1310733 此外，請參閱第五圖，其係為本案之環狀式列印裝置 内部結構之側面視圖。於實施例中，本案之定位機構20 係可設於一套設於一對滑軌40上之滑動板件41上，該滑 動板件41之底部設有一套件42,套件42套設於環狀式列 印裝置内部之一螺桿43,該螺桿43由一驅動機構所帶動， 使得套件42得以滑動於該螺桿43上，並一併使得滑動板 件41可帶動定位機構20來回平行移動。如此一來，進行 φ 列印時，列印組件10便可利用環型導執12來進行環狀的 列印，再利用滑動板件41來使得手指100連同滑動板件 41隨著定位機構20前後平行移動，當然更進一步的，於 設計上可於螺桿43之一處加設感測器（未圖示），如此一 來，當滑動板件41到達該感測器之感測位置時，便可阻 止滑動板件41繼續移動。其中，感測器的數量及位置並 無限定，如果想要更精確，亦可於螺桿43之前後皆設置 感測器。而且，本案之環狀式列印裝置之定位機構20係 * 可加設一辅助固定元件27，當手指100放入容置空間21 後，還可綑綁或定位手指1〇〇之另一端，也就是手掌及手 腕的部位，以防止手指100於列印的過程中，不小心向後 退縮而影響列印進行的困擾。當然，辅助固定元件27的 使用方式並無限定，通常可以繫帶為之，材質可選自塑膠 或皮件等等，且輔助固定元件27上可加設魔鬼粘，以加 強輔助固定元件27的固定性。 當然，本案之環狀式列印裝置係可設有多組容置空 間，以同時對多個手指之指曱進行列印。以本案所舉之實 13 Ϊ310733 施例來說，請再次參閱第三圖，本案之環狀式列印裝置係 同時設有六組容置空間21，其中最左端以及最右端之容置 空間21與中間四組容置空間21係設有一段距離，如此一 來，使用者便可同時將整個右手或整個左手的手指1〇〇放 入各自對應的容置空間21中，並且推動定位桿24之後就 可使每個手指1〇〇的指甲101凸出於各容置空間21的開 口 211中，利用滑座22、彈性元件221以及夾持定位元件 • 25的作用，確實定位手指100的位置。隨後，再使列印材 料匣11運行於環型導執12上，以對指甲101進行環狀式 列印，待列印完成後，再一次將手指100抽出來。因此， 本案之環狀式列印裝置與習知的不同還在於，本案之環狀 式列印裝置係可同時適用於左手與右手，並且同時列印多 個手指之指甲，而不再如同傳統般的僅能等一個列印完成 後，再列印另一個指曱。 更重要的是，本案之環狀式列印裝置列印的作動軌跡 ® 係為圓弧形，因此所能應用之待列印物件不再侷限於平面 或直線的物件，而是可應用於具有曲面的物件，例如指曱 或是其他曲面物件等等。與第一圖所示之列印軌跡相比， 請參閱第六圖，其係為本案之環狀式列印裝置之作動軌跡 與曲面待列印物件之關係示意圖。其中本案之環狀式列印 裝置所進行列印軌跡Τ2呈圓弧狀，且待列印物件Α之表 面S2亦呈圓弧狀，因此很清楚地，於本案所揭露之技術 中，縱使列印執跡T2與待列印物件之表面S2的曲率半徑 不同，但是該待列印物件為一與環型軌道曲率半徑同向， 14 1310733 故列印組件與待列印物件間的距離變異值會有效的縮減 其差異，一較佳實施例，其環型導軌曲率半徑可為5公分 至15公分，而複數曲面之曲率半徑為0.5公分至5公分。 不難想像的，本案之環狀式列印裝置對於具有圓弧曲 面之物件所能完成之列印效果會遠遠的優於傳統之列印 裝置所能完成之列印效果。 綜上所述，本案之環狀式列印裝置藉由環型導執配合 滑動板件之設計，即可進行各方向的列印。尤其是，當待 列印物件放入後，還可先透過列印組件之感測元件來確認 待列印物件之位置，再使列印組件之列印材料匣於環型導 軌上進行環狀式的列印，又藉由滑動板件帶動定位機構， 使待列印物件進行直線式的移動，大大的增加傳統列印裝 置所不能達成的列印功效。是以，本案之環狀式列印裝置 極具產業之價值，爰依法提出申請。 本案得由熟知此技術之人士任施匠思而為諸般修 飾，然皆不脫如附申請專利範圍所欲保護者。 15 !310733 【圖式簡單說明】 第一圖：其係為傳統之列印裝置之作動軌跡與曲面待列印 物件之關係示意圖。 第一圖··其係為本案之環狀式列印裝置之應用示意圖。 第二圖：本案之環狀式列印裝置内部結構之正面視圖。 第四圖⑷與(b):本案之環狀式列印裝置之定位機構之剖面

In this way, when the φ printing is performed, the printing assembly 10 can perform the annular printing by using the ring type guide 12, and then the sliding plate member 41 is used to make the finger 100 together with the sliding plate member 41 along with the positioning mechanism 20 Parallel movement in front and rear, of course, further, a sensor (not shown) can be added to one of the screws 43 in design, so that when the sliding plate 41 reaches the sensing position of the sensor, It is possible to prevent the slide plate 41 from continuing to move. Among them, the number and position of the sensors are not limited. If you want to be more precise, you can also set the sensors before and after the screw 43. Moreover, the positioning mechanism 20 of the annular printing device of the present invention can be provided with an auxiliary fixing member 27, and when the finger 100 is placed in the accommodating space 21, the other end of the finger 1 can also be bundled or positioned. It is the part of the palm and wrist to prevent the finger 100 from being retracted in the process of printing, which affects the trouble of printing. Of course, the manner of using the auxiliary fixing component 27 is not limited. Generally, it can be strapped, the material can be selected from plastic or leather, and the auxiliary fixing component 27 can be attached with a devil glue to strengthen the auxiliary fixing component 27. Fixed. Of course, the ring printing device of the present invention can be provided with a plurality of sets of accommodating spaces for printing fingerprints of a plurality of fingers at the same time. In the case of the actual 13 Ϊ 310733 example, please refer to the third figure again. The annular printing device of the present case is provided with six sets of accommodating spaces 21, wherein the leftmost and rightmost accommodating spaces 21 are provided. The distance between the four sets of accommodating spaces 21 is set at a distance, so that the user can simultaneously put the fingers of the entire right hand or the entire left hand into the corresponding accommodating spaces 21 and push the positioning rods 24 . Then, the nail 101 of each finger can be protruded from the opening 211 of each accommodating space 21, and the position of the finger 100 can be surely positioned by the action of the slider 22, the elastic member 221, and the clamping positioning member 25 . Subsequently, the printing material 11 is further operated on the ring guide 12 to perform ring printing on the nail 101. After the printing is completed, the finger 100 is again taken out. Therefore, the ring-shaped printing device of the present invention is different from the conventional one in that the ring-shaped printing device of the present invention can be applied to both the left hand and the right hand at the same time, and simultaneously prints the nails of a plurality of fingers instead of the conventional one. You can only print another fingerprint after waiting for one print to complete. More importantly, the actuating track® printed by the ring-shaped printing device of the present invention is a circular arc shape, so that the object to be printed that can be applied is no longer limited to a flat or straight object, but can be applied to have Surface objects, such as fingerprints or other curved objects. Compared with the print track shown in the first figure, please refer to the sixth figure, which is a schematic diagram of the relationship between the action track of the ring type printing device and the surface to be printed. In the circular printing device of the present case, the printing track Τ2 is in an arc shape, and the surface S2 of the object to be printed is also in the shape of an arc, so it is clear that in the technique disclosed in the present case, even the column The printing trace T2 is different from the radius of curvature of the surface S2 of the object to be printed, but the object to be printed is in the same direction as the radius of curvature of the annular track, 14 1310733, so the distance variation between the printing component and the object to be printed is The difference can be effectively reduced. In a preferred embodiment, the radius of curvature of the annular guide rail can be 5 cm to 15 cm, and the radius of curvature of the complex curved surface is 0.5 cm to 5 cm. It is not difficult to imagine that the circular printing device of this case can achieve a printing effect far superior to that of a conventional printing device for an object having a circular curved surface. In summary, the ring type printing device of the present invention can perform printing in all directions by the design of the ring type guide and the sliding plate member. In particular, after the object to be printed is placed, the position of the object to be printed can be confirmed by the sensing component of the printing component, and then the printing material of the printing component is placed on the ring rail for ringing. The printing of the type, by sliding the plate member to drive the positioning mechanism, linearly moves the object to be printed, greatly increasing the printing effect that cannot be achieved by the conventional printing device. Therefore, the ring-type printing device of this case is of great industrial value and is submitted in accordance with the law. This case has been modified by people who are familiar with the technology, but it is not intended to be protected by the scope of the patent application. 15 !310733 [Simple description of the diagram] The first picture: it is a schematic diagram of the relationship between the trajectory of the traditional printing device and the surface to be printed.
