201114618 [印刷裝置] 如第1圖、第2圖所示，構成衛星型印刷裝置，具備有 :驅動旋轉的中心鼓1、沿著該中心鼓1的外周配置的複數 的印刷單元2 (印刷部的一個例子）、以及對進行過印刷 的被印刷物P的印刷面照射紫外線的紫外線照射部3 (紫外 線照射半導體發光元件光源的一個例子）。 該印刷裝置，將以滾筒狀設置在供給部5的薄片狀的 被印刷物P，藉由導引滾子6連續地供給到中心鼓1，伴隨 著中心鼓1的旋轉，對於被印刷物P的表面，讓印刷單元2 藉由凸板印刷方式以紫外線硬化型墨水進行印刷，紫外線 照射部3對於該印刷之後的印刷面進行紫外線的照射來使 紫外線硬化型墨水硬化。 各個印刷單元2，其數量具備有對應於黑色（κ)、青 色（C )、品紅色（Μ )、黃色（Υ )的至少四種顏色。如 圖面所示’複數的印刷單元2，對應於黑色（Κ)、靑色（ C )、品紅色（Μ )、黃色（Υ )，具有 2Κ、2C、2Μ、2Υ 的圖號。圖中2Ρ’是爲了表面加工等的目的而進行透明墨 水（ΟΡ )的印刷。 紫外線照射部3，如第3圖所示，可自由卸下地安裝著 :具有多數的紫外線發光二極體D(參考第6圖、第7圖， 半導體發光元件的一個例子）的LED單元20 (半導體發光 元件單元的一個例子）。該LED單元20，其功能爲：藉由 對於利用各印刷單元2以紫外線硬化型墨水所印刷的印刷 -10- 201114618 面照射紫外線，使該墨水硬化。作爲該紫外線照射部，也 可取代紫外線發光二極體D，使用紫外線雷射二極體，或 使用會發出紫外線光的雷射光源。 複數的LED單元20，其形狀、尺寸都作得相同，以在 印刷裝置的被印刷物P的搬運路線爲基準，從設定在與該 搬運路線正交的方向的其中一方（被印刷物p寬度方向的 其中一方）的作業區域S，作業者（操作者）進行安裝與 卸下。 如第2圖〜第5圖所示’在印刷裝置具備有：將中心鼓 1的驅動軸1〇的兩端可自由旋轉地予以支承的板狀的一對 側框架11，形成有··對於其中一方的驅動軸傳達來自電 動馬達8的驅動力的傳動系統9。對於一對側框架11可自由 旋轉地支承著導引滾子6，在印刷裝置的其中一方的端部 配置有滾筒狀的被印刷物的供給部5。 在於一對側框架1 1處具備的托架1 2連結著附件1 5，對 於該附件15藉由滑動操作可自由安裝及卸下地支承著LED 單元20。托架12，具有：形成有也可安裝水銀燈型的紫外 線光源的開口 1 2 A的構造，在與該一對托架1 2的開口 1 2 A 鄰接的位置，以螺拴固定著附件1 5。 附件15，其形狀爲有底角管狀，且在長軸方向的兩端 形成有凸緣部1 6 ’在側面形成有狹縫狀的導引溝1 5 G，在 另一個側面形成有開口 1 5 W。在該附件1 5的內端具備有： 抽出式連接器的插座部17、以及與LED單元20之間以非接 觸方式進行辨別資訊的接達的天線單元1 8。在附件1 5之中 -11 - 201114618 具備有插座部17的附件15的外面（作業區域s的相反側） 具備有電源裝置P S »複數的附件丨5其形狀、尺寸都作得相 同，也可安裝任何的LED單元20。 [LED單元] L E D單元2 0 ’具有：在其中一面形成有紫外線射出部 20A的構造，能以任意的姿勢使用，而如第6圖 '第7圖所 示，是根據紫外線射出部20 A在上面的姿勢來說明構造。 如第3圖〜第7圖所示，LED單元20，是將紫外線射出 部20A形成在上面的箱狀，在除了紫外線射出部2〇a的側 面，具有.：形成有多數通氣用的護柵部的壁部。在該LED 單元20的側面，空轉支承著：可與上述導引溝15G卡合的 導引滾子21，在其中一方的端部具備有把手22。在該端面 具備有：在作爲顯示手段的顯示面形成有觸碰式面板的液 晶顯示器23。並且在該LED單元20的另一方的端面，具備 有：抽出式連接器的插頭部24、及以RFID ( Radio Frequency IDentification)所構成的辨別資訊記錄手段25 。在該辨別資訊記錄手段25針對各LED單元20記憶原有（ 唯一的）的辨別資訊。 上述導引溝15G，是由：在LED單元20的裝入方向也 就是印刷寬度方向直線狀地延伸的直線部分、以及從該直 線部分朝接近中心鼓1的方向分歧或彎曲的三個彎曲部所 構成。並且該彎曲部包含有：從直線部分分歧而朝接近中 心鼓1的方向傾斜延伸的傾斜溝部、以及從該傾斜溝部的 -12- 201114618 前端彎折而與直線部分平行地小幅延伸的端溝部。該彎曲 部彼此的間隔，是配合導引滾子2 1的配置間距，三個導引 滾子2 1藉由被各彎曲部的傾斜溝部導引，而使離開印刷面 不會造成干涉地插入的LED單元20的紫外線射出部20A， 朝對於被印刷物接近的方向移位。接著藉由將導引滾子21 導引於端溝部，讓插座部17與插頭部24連結而達到電連接 狀態。藉由讓作業者從作業區域S握住把手2 2進行拉動操 作，朝相反方向從彎曲部朝直線方向連續導引導引滾子2 1 ，則可從附件I5將LED單元20抽出。 三個分歧部或彎曲部之中在插入方向的下游側的兩個 間隔、以及與連續的分歧部（作業區域S側的構造）的間 隔，作成不同，對應於該間隔配置有三個導引滾子2 1。藉 此，當將LED單元20插入於附件15時，即使前頭的導引滾 子21到達了進入於對應的分歧部以外的分歧部的位置，接 下來的導引滾子2 1也不會到達分歧部，所以可以防止進入 到不對應的分歧部的不適當情形。也就是說，在LED單元 20的插入方向的三個分歧部的間隔、與三個導引滾子21的 間隔設定成相等，會導致前頭的導引滾子2 1進入到原來不 對應的分歧部這樣不適當的情形，藉由將其間隔設定成不 均等，防止導引滾子2 1進入到不對應的分歧部的不適當的 情形，可實現將對應導引滾子2 1導入對應分歧部。 如第6圖所示，三枚防污板2 6，是沒有間隙地被支承 於框體26F的內周，在框體26F的長軸方向的其中一方的端 部一體地形成有把手26G。 -13- 201114618 爲了使防污板26的密封性能提高，在框體26F的外周 部分或滑動溝27G具備有密封構件也可以。並且，爲了對 於具備有紫外線發光二極體D (半導體發光元件的一個例 子）的空間防止灰塵等侵入，在基板28與反射構件27的接 觸面具備有密封構件也可以。 在反射構件27，使用了鋁或不鏽鋼等的金屬材料，藉 由硏磨該材料而精加工成鏡面，而在上側形成有反射面 2 7R，在下側形成有：將基板28所支承的複數的紫外線發 光二極體D予以收容的凹部。在反射構件27的表面側（上 側），以平行姿勢形成有一對滑動溝27G，該一對滑動溝 27G是可自由滑動地支承著框體26F。該滑動溝27G，在 LED單元20安裝於印刷裝置的狀態，是朝作業區域S的方 向開放，可從該開放部分對於滑動溝2 7 G，與框體2 6 F —體 地進行防污板2 6的插拔。 框體26F是以包含鐵或鎳的合金等的磁性體所構成， 在反射構件27具備有：當將防污板26對滑動溝27G插入至 適當的安裝位置時，吸附框體26F的永久磁鐵Mg。藉由該 磁性體的框體26F與永久磁鐵Mg構成了保持機構，作業者 從作業區域S握住把手26G，則可進行防污板26的插入操作 的安裝、以及可利用抽出操作進行卸下，當已插入至適當 的安裝位置時’永久磁鐵M g吸附著框體2 6 F的端部而維持 著安裝狀態。 作爲保持機構’在框體2 6F具備有永久磁鐵Mg，在反 射構件27具備有鐵片等的磁性體也可以。作爲保持機構， -14 - 201114618 在框體26F形成有凹部，當框體2“插入至適當的位置時， 使用藉由具備有卡合於凹部的彈簧體等，機械性地保持安 裝狀態的構造也可以。 防污板26 ’在安裝狀態，與反射構件27的反射面27R 成爲平行姿勢，框體26F的下面緊貼於反射構件27的上面 。藉此’防污板26’將具備有紫外線發光二極體d的空間 與外部空間予以隔絕’將具備有紫外線發光二極體D的空 間維持在密封狀態。 當對紫外線硬化型墨水照射紫外線時，確認有：在紫 外線硬化型墨水的成分的一部分昇華或蒸發之後，附著於 附近的構件而析出的現象。在該析出物附著在紫外線發光 二極體D的表面的情況’會讓紫外線的光量降低，而由於 以防污板2 6將具備有紫外線發光二極體〇的空間密封，所 以能防止析出物附著到紫外線發光二極體D或反射構件2 7 的表面。雖然導致析出物附著於防污板26，而作業者藉由 將該防污板26與框體26F—體地卸下而擦拭，則可將析出 物去除，則不會導致紫外線量降低。 如第8圖所示’將1 0個紫外線發光二極體〇作成一單位 ’以形成有絕緣面的帶狀的支承體2 8 A，將該紫外線發光 —極體D支承爲直線狀，是對於基板28可卸下地支承著該 支承體28A。即使在一單位之中的—個紫外線發光二極體 D的光量降低時’也可進行··用來支承丨〇個紫外線發光二 極體D的支承體28A的更換。 如該圖所示’紫外線發光二極體D爲五列，以讓鄰接 -15- 201114618 的紫外線發光二極體D交錯狀配置的方式，來設定支承體 28A的相對位置關係。藉由讓紫外線發光二極體〇列之中 鄰接的的位置彼此交錯狀配置，則可解決：列方向的光量 不均勻的現象。而被支承體28A所支承的紫外線發光二極 體D的數量並不限於1〇個，數量是小於1〇個或超過10個都 可以。 尤其在具備有五列的複數的紫外線發光二極體D之中 ’在被印刷物P的搬運方向的上游側，配置有：波長爲 3 8 5nm的性能的兩列的紫外線發光二極體D，在該搬運方 向的下游側，配置有：波長爲3 65nm的性能的三列的紫外 線發光二極體D。 藉由像這樣在被印刷物P的搬運方向的上游側配置波 長較長的紫外線發光二極體D，在其下游側配置配置波長 較短的紫外線發光二極體D，藉由波長較長的紫外線使紫 外線到達墨水的內部，從內部進行硬化，接著藉由波長較 短的紫外線來確實地進行墨水表面的硬化。 以讓光線從該五列的紫外線發光二極體D直線送出的 方式，來設定反射構件27的狹縫狀開口 27S的位置。將從 狹縫狀開口 27S所送出的紫外線照射到被印刷物P的表面， 以被印刷物P的印刷面反射的紫外線到達反射面2 7 R，以該 反射面2 7 R反射，.再送出到被印刷物p的印刷面。 內部外殼30，具有護柵部，從散熱部29的部位連結到 將基板28覆蓋的位置。在該內部外殼30且在散熱部29的正 下方位置，具備有：將冷卻氣流供給到散熱部2 9的三個電 201114618 動型的冷卻風扇31。外部外殼32，具有護柵部，配置於將 冷卻風扇31覆蓋的位置而連結於內部外殼30。 在第一端面外殼33具備有上述把手22與液晶顯示器23 ，在其相對向位置所配置的第二端面外殻34，具備有：上 述插頭部24、與辨別資訊記錄手段2 5。 在第一端面外殻33形成有狹縫33S，該狹縫33S可進行 除塵過濾器35的插入與拔出，除塵過濾器35是用來將供給 到冷卻風扇3 1的空氣所含有的灰塵予以去除。除塵過濾器 35，被在除塵過濾器35的厚度方向具有預定寬度的矩形框 架3 5F所支承，在該框架35F的端部形成有作業者可抓持的 把手部35G。形成於第一端面外殼33的狹縫33S，是形成爲 框架35F可自由插拔的尺寸。藉由具備該框架35F，則即使 在將除塵過濾器3 5抽出時，也能防止：附著於除塵過濾器 35的表面的灰塵接觸到狹縫33S的開口緣而脫落的不好的 情形。. 由於具備有這種冷卻系統，經由外部外殼3 2的底部側 的護柵部所吸引的外氣’會在以除塵過濾器35除去灰塵的 狀態，被冷卻風扇3 1所吸引’對於散熱部2 9供給，從內部 外殻30的側面的護柵部排出到單元外部。 [紫外線的照射] 在本發明的LED單元20，沿著與被印刷物p的搬運方 向正交的方向，將複數的紫外線發光二極體D配置成直線 狀，所以來自複數列的紫外線發光二極體D的光線，從複 •17- 201114618 數列的狹縫狀開口 27S送出’並且在穿透防污板26的型態 到達被印刷物P的印刷面。 在這樣進行紫外線的照射時，如上述藉由容易穿透墨 水的較長波長的紫外線，先進行墨水之中與被印刷物P接 觸的部分（下層部分）的硬化，然後，藉由較短波長的紫 外線進行外面側墨水的硬化，則可解決下層墨水沒有硬化 的不適當情況。 尤其是照射到印刷面的紫外線的一部分被印刷面反射 ，朝向LED單元20反射，如上述，將印刷面反射的紫外線 ，藉由LED單元20的反射構件27的反射面27R將其反射， 將紫外線再送出到印刷面’則不會浪費紫外線，能促進紫 外線硬化墨水的硬化。 [電力控制系統] 如第9圖所示，電源裝置PS，是具備有：定電壓電路 51、複數的定電流電路52、風扇電源電路53、及電源管理 單元54。定電壓電路51，是從來自外部所供給的電路（商 用電源）供給爲作爲目標電壓的直流電力。定電流電路52 ’將從定電壓電路5 1所供給的電力供給爲設定的電流値。 風扇電源電路53，從來自外部所供給的電路（商用電源） 來供給風扇驅動用電力》電源管理單元54，根據經由通訊 迴路L所送到的控制訊號，將具有繼電器或半導體開關元 件等的開關電路55進行操作，進行對於定電壓電路51的電 力的供給與阻斷的切換控制，並且進行將定電壓電路51的 -18- 201114618 設定電壓予以調節的電力控制。 電源管理單元54可經由通訊迴路L從管理部（沒有圖 示）進行訊號的接達，同樣的，天線單元18也可經由通訊 迴路L從管理部（沒有圖示）進行訊號的接達。雖然沒有 詳細敘述控制型態，而藉由從管理者經由通訊迴路L接收 訊號，電源管理單元54可達成開關電路55的ON、OFF，達 成對定電壓電路51的電壓調節。 1 〇個紫外線發光二極體D是電連接成串聯，定電流電 路52具備有支承體28 A的數量。如該圖所示，將來自各個 定電流電路52的電流，供給到對應的支承體28 A的10個紫 外線發光二極體D，將來自風扇電源電路5 3的電力供給到 冷卻風扇3 1，而構成電力供給系統。 如該圖所示，在LED單元20具備有：經由天線部56A 而與天線單元1 8之間進行無線通訊的通訊單元5 6、及用來 控制液晶顯示器23的顯示控制部57。 在該電力控制系統，將從外部供給的電力（商用電源 )’從定電壓電路5 1經由定電流電路5 2供給到一單位的紫 外線發光二極體D來進行發光，並且從風扇電源電路5 3供 給到冷卻風扇3 1進行冷卻風扇3 1的驅動。電源管理單元5 4 ’如第1 0圖所示，不只是根據從控制部4 0經由通訊迴路L 所傳輸的資訊來進行電力的供給與阻斷的切換控制，也可 使定電壓電路5 1的設定電壓上升而達到增加供給電力。 通訊單元5 6 ’將從控制部4〇經由通訊迴路L所傳輸的 資訊’經由天線部5 6 A而取得，顯示控制部5 7將取得的資 -19- 201114618 訊顯示在液晶顯示器23 °這裡的控制與控制部40的控制在 後面一同敘述。 [控制構造] 如第1 〇圖所示構成印刷裝置的控制系統。在該控制系 統，具備有以通用電腦所構成的控制部40 ’用來管理複數 的LED單元20，具備有螢幕Μ與鍵盤K。控制部40具備有通 訊部42，該通訊部42是經由以電纜所構成的通訊迴路L而 與電源裝置PS與天線單元18連接。 控制部40，具備有：單元辨別手段43、累計手段44A 、發光時間記錄手段44B、發光時間管理手段45、供給電 力設定手段46、與資訊輸出手段47;並且在供給電力設定 手段46具備有電力調整圖表4 6T，具備有：用來送出累計 手段44A時間資訊的計時器48。計時器48即使在控制部40 的電源爲OFF狀態，也具備有能產生年月日時間資訊的備 用電源。[Technical Field] The present invention relates to a printing apparatus in which a plurality of printing sections that are printed by ultraviolet curable ink are disposed along the conveyance direction of a printed matter to be created in each printing section. The semiconductor light-emitting element unit having the ultraviolet light-emitting semiconductor light-emitting element at the downstream position is transported, and the semiconductor light-emitting element light source that irradiates the printed surface of the printed matter with ultraviolet light is disposed. [Prior Art] Patent Document 1 discloses a convex plate roller printer in which a plurality of printing device units are disposed along the outer peripheral surface of the platen roller, and an ultraviolet irradiation device is disposed on the downstream side. In the slat roller printing machine, a soft vinyl chloride film or the like as a printed matter is supplied to an impression cylinder, and for the film or the like, the printing device unit is subjected to roll printing by ultraviolet curable ink, and then printed by an ultraviolet ray irradiation device. The surface is irradiated with ultraviolet rays to cure the ultraviolet curable ink. Patent Document 1 describes that a metal halide lamp is used as the ultraviolet irradiation device, and a chemical lamp or an ultrahigh pressure mercury lamp can be used. Patent Document 2 discloses an ink jet recording apparatus including a recording head for discharging ultraviolet curable photocurable ink onto a recording medium, and a light irradiation device for irradiating the discharged ink with ultraviolet rays. In the ink jet recording apparatus, the light irradiation device is moved together with the recording head to irradiate the ultraviolet curable ink discharged to the recording medium with ultraviolet rays to achieve ink hardening. -5- 201114618 The light irradiation device ’ is composed of a plurality of ultraviolet light-emitting diodes and has a plurality of blocks. [Prior Art] [Patent Document 1] [Patent Document 1] 曰本特开平1 1 - 1 7068 3 (Paragraph No. [〇〇1〇]~ [0029], 1st) [Patent Document 2] 曰JP-A-2008-143123 (Paragraph No. [〇〇37] to [0063], FIG. 1 to FIG. 4) [Problems to be Solved by the Invention] The printing device described in Patent Document 1, Printing with an ultraviolet curable ink, and ultraviolet light is applied to the printed surface after printing, and the ultraviolet curable ink is rapidly hardened. As an ultraviolet light source for hardening an ultraviolet curable ink, a commercial pressure mercury lamp is generally used from the viewpoint of obtaining a sufficient amount of light and the cost of the lamp. Although high-pressure mercury lamps are easy to obtain high output, in reality, a light source used in a printing device consumes more than one kilowatt of power, the power supply voltage is high, and high insulation is required in the power supply system. In the high-pressure mercury lamp, the power supply device including the ballast not only causes an increase in size, but also needs to be replaced when the usage time reaches about 2,000 hours, and there is room for improvement. 201114618 Therefore, the structure described in Patent Document 2 is also considered. The ultraviolet light emitting diode constitutes an ultraviolet light source. The ultraviolet light source using the ultraviolet light emitting diode exhibits energy saving and long service life. Even if an ultraviolet light-emitting diode is used, it needs to be repaired every time it is reached, or it needs to be replaced when it reaches the limit of use. However, for example, the operator uses a man-made job to grasp the maintenance period or the timing of replacement by using a management record, etc. 'Because of the long time, it is easy to cause an error. Especially in the printing device, multi-color printing can be performed, and two-color or three-color printing can also be performed. 'In this printing', the ultraviolet light source that is not used in the printing portion of the printing is turned off. There is a difference in time (cumulative time), and it is not easy to grasp the maintenance period or the timing of replacement. There is still room for improvement. SUMMARY OF THE INVENTION An object of the present invention is to provide a printing apparatus which can easily realize a long service life of an ultraviolet light source and which can be easily managed according to the light emission time of the ultraviolet light source.

The bracket 1 2 provided at the pair of side frames 1 1 is coupled to the attachment 15 , and the LED unit 20 is detachably supported by the attachment 15 by a sliding operation. The bracket 12 has a structure in which an opening 1 2 A of a mercury lamp type ultraviolet light source can be attached, and the attachment 15 is screwed at a position adjacent to the opening 1 2 A of the pair of brackets 1 2 . . The attachment 15 has a bottomed-angled tubular shape, and a flange portion 16 is formed at both ends in the longitudinal direction. A slit-shaped guide groove 1 5 G is formed on the side surface, and an opening 1 is formed on the other side. 5 W. The inner end of the accessory 15 is provided with a socket portion 17 of the draw-out type connector, and an antenna unit 18 that communicates with the LED unit 20 in a non-contact manner. In the case of Annex 1-5, -11 - 201114618, the outer surface of the accessory 15 having the socket portion 17 (opposite side of the work area s) is provided with the power supply device PS » the plurality of accessories 丨 5 having the same shape and size. Install any LED unit 20. [LED unit] The LED unit 20 0 has a structure in which the ultraviolet light emitting portion 20A is formed on one surface thereof, and can be used in an arbitrary posture, and as shown in Fig. 6 'Fig. 7 , according to the ultraviolet light emitting portion 20 A The above poses to illustrate the construction. As shown in FIG. 3 to FIG. 7, the LED unit 20 has a box shape in which the ultraviolet light emitting portion 20A is formed on the upper surface, and has a grille for forming a plurality of ventilations on the side surface of the ultraviolet light emitting portion 2A. The wall of the department. On the side surface of the LED unit 20, a guide roller 21 engageable with the guide groove 15G is idly supported, and one end portion thereof is provided with a handle 22.

The 'anti-fouling plate 26' will be provided with ultraviolet rays. The space of the light-emitting diode d is isolated from the external space. The space in which the ultraviolet light-emitting diode D is provided is maintained in a sealed state. When the ultraviolet-curable ink is irradiated with ultraviolet light, it is confirmed that the ultraviolet-curable ink has a composition. After a part of sublimation or evaporation, it is deposited by a nearby member and precipitates. When the precipitate adheres to the surface of the ultraviolet light-emitting diode D, the amount of ultraviolet light is lowered, and the anti-fouling plate 26 is provided.

The precipitate adheres to the anti-fouling plate 26, and the operator wipes the anti-fouling plate 26 and the frame body 26F in a body-like manner, so that the precipitate can be removed without causing a decrease in the amount of ultraviolet rays. As shown in the figure, '10 ultraviolet light-emitting diodes are made into one unit' to form a strip-shaped support body 28A having an insulating surface, and the ultraviolet light-emitting body D is supported in a straight line for the substrate 28 The support body 28A is detachably supported. Even when the amount of light of the ultraviolet light-emitting diode D in one unit is lowered, the support body for supporting the ultraviolet light-emitting diodes D can be carried out. Replacement of 28A. As shown in the figure, the ultraviolet light-emitting diodes D are five rows, and the relative positional relationship of the support bodies 28A is set so that the ultraviolet light-emitting diodes D adjacent to -15 to 201114618 are arranged in a staggered manner.

The position of the slit-like opening 27S of the reflecting member 27 is set so that the light is sent straight out from the five rows of the ultraviolet light-emitting diodes D. The ultraviolet ray sent from the slit-shaped opening 27S is irradiated onto the surface of the object P to be printed, and the ultraviolet ray reflected by the printing surface of the printed matter P reaches the reflecting surface 2 7 R, and is reflected by the reflecting surface 277 R. The printed surface of the printed matter p. The inner casing 30 has a grill portion that is connected from a portion of the heat radiating portion 29 to a position where the substrate 28 is covered.

The dust filter 35 is supported by a rectangular frame 35F having a predetermined width in the thickness direction of the dust filter 35, and a handle portion 35G which the operator can grip is formed at the end of the frame 35F. The slit 33S formed in the first end face casing 33 is formed to have a size in which the frame 35F can be freely inserted and removed. By providing the frame 35F, even when the dust filter 35 is taken out, it is possible to prevent the dust adhering to the surface of the dust filter 35 from coming into contact with the opening edge of the slit 33S and falling off. With such a cooling system, the outside air 'which is sucked through the grille portion on the bottom side of the outer casing 32 will be attracted by the cooling fan 31 in a state where the dust is removed by the dust filter 35. The supply is discharged from the grill portion on the side of the inner casing 30 to the outside of the unit. [Ultraviolet light irradiation] In the LED unit 20 of the present invention, a plurality of ultraviolet light-emitting diodes D are arranged in a straight line along a direction orthogonal to the conveyance direction of the printed matter p, so that ultraviolet light-emitting diodes from a plurality of columns are arranged. The light of the body D is sent out from the slit-shaped opening 27S of the series of 17-201114618 and passes through the type of the anti-fouling plate 26 to reach the printing surface of the printed matter P. When the ultraviolet ray is irradiated in this way, as described above, by the ultraviolet ray of a longer wavelength which easily penetrates the ink, the portion of the ink which is in contact with the object P to be printed (the lower layer portion) is first hardened, and then, by a shorter wavelength. Ultraviolet light hardening of the outer side ink can solve the problem that the lower layer of ink is not hardened. In particular, a part of the ultraviolet ray that has been irradiated onto the printing surface is reflected by the printing surface and is reflected toward the LED unit 20. As described above, the ultraviolet ray reflected by the printing surface is reflected by the reflecting surface 27R of the reflecting member 27 of the LED unit 20, and the ultraviolet ray is reflected. When it is sent to the printing surface, it does not waste ultraviolet rays and promotes the hardening of the ultraviolet curing ink.

The accumulation means 44A accumulates the light emission time of each of the LED units 20, and then supplies it to the light emission time recording means 44B. The light emission time recording means 44B records the cumulative light emission time of each of the LED units 20. The light-emitting time recording means 44B records the accumulated light-emission time of the light-emitting date and time of the LED unit 20 in the light-emitting state as a cumulative time of light emission for a memory such as a hard disk or a non-volatile memory. The accumulating means 44A discriminates the state of the LED unit 20, and accumulates the date (the year and month of the ultraviolet illuminating illuminating) of each of the LED -20-201114618 units 20, and accumulates the specific information with respect to the illuminating cumulative time, so that the illuminating time is made. The recording means 4 4 B records the accumulated time (light emission cumulative time) of the lighting time. In particular, the illuminating time recording means 44B can discriminate the LED unit 20 exceeding the number of the ultraviolet ray irradiating portions 3 (e.g., twice the number of the ultraviolet illuminating portions 3), and record the illuminating cumulative time. In other words, although the printing unit is mounted with the same number of LED units 20' as the ultraviolet irradiation unit 3, for example, the LED unit 20 of the commonly used wavelength is replaced by the type or printing type of the ink, and the wavelength is used. Different LED units 20. In this case, the cumulative time of the light emission of the LED unit 20 having a small frequency of use is difficult to manage by a person, and since it is not limited to the frequency of use, the management of the light-emission integration time is performed for each of the LED units 20, so that appropriate management can be performed. . The light emission time management means 45 manages the output of the light emission cumulative time recorded in the light emission time recording means 44B. The power supply setting means 46 performs setting of ON, OFF, and power supply of electric power supplied from the plurality of power supply devices PS to the LED unit 20. The information output means 47 is composed of a maintenance information output means 47A and a replacement information output means 47B. The information to be displayed is output to the screen of the control unit 40 or the liquid crystal display 23 of each LED unit 20. The unit discrimination means 43, the accumulation means 44A, the illumination time recording means 44B, the illumination time management means 45, the supply power setting means 46, and the information output means 47 are formed of software, and may be formed of a hard body or may be formed of a hardware. It is composed of a combination of software and hardware. -21 - 201114618 [Light source management processing] In the printing apparatus, the LED unit 20 corresponding to the ink of the unused color is not illuminated by the number of colors of the ink used for printing. On the other hand, the amount of light of the LED unit 20 decreases with the lapse of the illuminating time, and it is difficult to stably illuminate after reaching the preset illuminating time. Therefore, when the set illumination accumulation time is reached, it is necessary to replace the LED unit 20 with new ones. As described above, the plurality of LED units 20 can be mounted to any of the accessories 15, so that the LED unit 20 is also inserted into a position different from the take-out position when servicing. This insertion is intentionally carried out by the operator in order to avoid the continuous emission of the specific LED unit 20, and it is also carried out unintentionally. In response to such a situation, the control unit 40 determines the state of each LED unit 20 to manage the cumulative time of light emission. The flowchart of Fig. 1 shows the control type of the control unit 40. That is, the reference 値 (time information) and the threshold 値 (time information) for performing light source management are set (step #101). In this control, the reference time is the cumulative time in which the amount of light is significantly lowered, and the time information corresponding to the period in which the cleaning of the antifouling plate 26 and the dust removing filter 35 should be performed, and is appropriately set to about 100 hours to 2000 hours. The so-called critical enthalpy is the cumulative time that needs to be replaced and is set to approximately 5,000 hours. Of course, the benchmark is set to be less than the critical threshold. Then, the unit identification information 43 acquires the discrimination information from the discrimination information recording means 25 via the antenna unit 18, and acquires the print mode information, thereby defining the LED unit 20 in the light-emitting state. The accumulating means 44A acquires the time information from the time measuring unit 48-22-201114618, accumulates the lighting time of each of the LED units 20 in the light-emitting state, and records the LED unit 20 discernibly in the lighting time recording means 44B (#1 02~# 1 04 ). In this control, the so-called print mode information includes information defining the colors used in printing. In this manner, after the respective LED units 20 can discriminately record the cumulative light emission time, the light emission time management means 45 determines whether or not there is a unit in which the cumulative light emission time exceeds the reference volume among the LED units 20. By this judgment, the LED unit 20 exceeding the reference volume increases the power supplied from the supply power setting means 46 based on the information from the maintenance information output means 47 A (#105, #106 step). In this processing, the LED unit 2A having the cumulative light emission time exceeding the reference volume is defined, and based on the information from the maintenance information output means 47A, the supply power setting means 46 can increase the power supplied to the defined LED unit 20. The degree of the increase is based on the degree that the cumulative time of the light emission exceeds the reference ,, and the power 値 for obtaining the amount of light as the target is calculated by referring to the power adjustment map 46T. The calculated power 値, as a parameter or the like, is transmitted to the power management unit 54 of the power supply device PS of the corresponding LED unit 20 via the communication loop L, and the power management unit 54 sets the constant voltage corresponding to the transmitted information. The set voltage of the circuit 51 rises, whereby the electric power of the ultraviolet light-emitting diode D supplied to the LED unit 20 is increased, and the amount of light is maintained. Although the flowchart is not shown, the control unit 40 has time information for the period of cleaning of the anti-fouling plate 26 and the dust filter 35 as a reference ,, and the cumulative time of the light emission, when the reference 値 is reached, the maintenance information is output. Hand -23- 201114618 Section 47A, a message indicating that the cleaning period of the anti-fouling plate 26 and the dust removing filter 35 is being performed is output to the screen Μ, and at the same time, the message at the time of cleaning is performed via the communication circuit L. The liquid crystal display 23 of the corresponding LED unit 20 is output. The light emission time management means 45 determines whether or not there is a cell in which the cumulative light emission time exceeds the critical threshold among the LED units 20. With this judgment, for the LED unit 20 exceeding the critical threshold, the replacement information output means 47B of the information output means 47 adds the discrimination information to the screen, and displays a message requiring the replacement of the LED unit 20, and via the communication loop L The message is transmitted to the LED unit 20, whereby a message requiring replacement is displayed for the liquid crystal display 23 of the LED unit 20 (#107, #10 8 steps). These control actions will continue (#109 step) to reset (power OFF). By displaying the message on the screen of the control unit 40, the operator can recognize that the LED unit 20 needs to be replaced with a new unit. The period or the time at which the cleaning of the anti-fouling plate 26 and the dust removing filter 35 is to be performed. This information is transmitted to the LED unit 20 via the communication circuit L. At the LED unit 20, the communication unit 56 obtains a message via the antenna unit 56A, and the display control unit 57 displays a message for the liquid crystal display 23. Thereby, the operator can perform the replacement of the LED unit 20 or the cleaning of the anti-fouling plate 26 and the dust removing filter 35 without making a mistake. In the flowchart, although the processing mode in which the message is displayed by the illuminating cumulative time exceeding the threshold 说明 is described, the information indicating that the LED unit 2 〇 is close to the replacement period can be displayed as the information before the illuminating cumulative time exceeds the critical threshold. 24- 201114618 Processing of interest. In this case, the time available before the replacement can also be displayed together with the message. As described above, although the control unit 40 for managing the plurality of LED units 20 has been described, the control unit of the present invention may be provided in the plurality of LED units 20. In this case, it is reasonable for the control unit to use the display control unit 57 of FIG. 10, and the display control unit 57 is configured to include the accumulation means 44A, the illumination time recording means 44B, and the illumination time management means 45. The information output means 47 sets the reference 値 and the threshold 对于 to the display control unit 57. The display control unit 57 supplies electric power to the LED unit 20, performs control when the ultraviolet ray is irradiated, and acquires the executed time information (time information of the ultraviolet ray irradiation) when the control is executed, and determines whether or not the illuminating cumulative time exceeds the corresponding reference 値. . At the same time, the cumulative time of luminescence is compared with the critical 値 to determine whether the critical enthalpy is exceeded. When the cumulative time of the light emission exceeds the reference level by the determination, a message for prompting the cleaning of the dust removing filter 35 or the cleaning of the dust removing filter 35 and the anti-fouling plate 26 is displayed on the liquid crystal display 23. When the message is displayed, the processing type can also be set to display a message indicating information close to the cleaning period before the cumulative time of illumination reaches the reference level. When the cumulative time of the light emission exceeds the critical threshold by the judgment, the liquid crystal display 23 displays a message indicating that the replacement timing of the LED unit 20 has been reached. For the display ', the processing type can be set to display information similar to the above, indicating that the information of the replacement period is close to the time before the illuminating cumulative time reaches the critical threshold. According to this display, the operator can perform cleaning of the dust filter 35 and the anti-fouling plate 26 or replacement of the LED unit 20 itself. In particular, in order to manage the lighting time in the LED single--25-201114618 element 20, the processing type can be set such that the recording information recording means 25 is used as the lighting time recording means, and the light-emitting integration is recorded for the discrimination information recording means 25. time. The present invention can also be set to control the LED unit 20 of a plurality of printing apparatuses by one control unit 40. With such a configuration, the management of the LED unit 20 set in a plurality of printing apparatuses can be performed by one control unit 40. When the replacement of the LED unit 20 is performed, the operator can hold the handle 22 of the LED unit 20 from the work area s and remove it. Similarly, when cleaning is performed, the operator can hold and remove the handle portion 35G of the dust removing filter 35 or the handle 26G of the anti-fouling plate 26 from the work area S. In the present invention, since the LED integration unit 20 is provided in a state in which the plurality of LED units 20 provided in the printing apparatus are discriminated, the LED integration unit 20 is mounted on any of the plurality of ultraviolet irradiation units 3, and the cumulative time for the light emission exceeds the reference. The unit of 値 uses the increased power supply to maintain the amount of light. The cell for displaying the illuminating cumulative time exceeding the critical threshold is displayed on the screen of the control unit 40 and the liquid crystal display 23 of the corresponding LED unit 20, so that the operator recognizes that the replacement period is reached, and the LED is not mistakenly placed. Unit 20 is renewed. Then, the cleaning time of the dust removing filter 35 and the cleaning timing of the anti-fouling plate 26 are appropriately grasped based on the cumulative lighting time recorded by the integrating means 44A, and the cleaning operation can be performed on time.
