200827711 九、發明說明： 【發明所屬之技術領域】 本發明有關於用於例如在圖像處理檢查等中對被檢查 物體進行照亮的照明裝置。 5 【先前技術】 以往以來，在生產線上對印刷配線基板或半導體等工 業製品的品質，例如焊錫（/、y夕、、）附著不良或異物等或 者在飲料用罐上印字的製造日期之類的錯誤等印刷錯誤進 10行檢查時，進行利用基於CCD攝影機等的攝影的圖像處理 檢查。在該圖像檢查處理中，使用用於對配置於照明區域 的被檢查物進行照明的照明裝置。 這種照明裝置備有多個發光元件以及安裝多個發光元 件的安裝基板（例如，參照專利前案！）。發光元件，由炮 15彈型LED或在其上表面具有發光部的晶片狀LED構成，多個 發光元件在安裝基板的一個面上隔著規定間隔地以線狀配 置。若多個發光元件各自發光，則來自多個發光元件的光， 向著配置於照明區域的被檢查物而照射，由此被檢查物以 線狀被照射。 20 [專利前案1]特開平9-130545號公報。 然而在上述那樣的以往的照明裝置中，存在如下問 題。所存在的問題爲，若使用電子部件安裝裝置而在安裝 基板的一個面上安裝多個發光元件（安裝），則由於電子 部件安裝裝置方面的問題，不能夠使多個發光元件的配置 5 200827711 間隔太小，因此，多個發光元件的安裝密度降低，在借助 於來自多個發光元件的光對被檢查物進行照明時會産生照 度不均。另外，爲了消除這一問題，在例如將多個發光元 件以多數列線狀配置於安裝基板的一個面側的情況下，若 5 例如由直徑爲3mm的炮彈型LED構成發光元件，則照明裝 置見度方向的大小需要確保在6mm以上，因此，存在裝置 整體的大型化問題。 本發明的目的在於提供一種照明裝置，其能夠以大致 _ 均一的照度對被檢查物進行照明，並能夠使裝置整體的尺 10

However, the surface 20 may be mounted on the side of the mounting boards 34Fa to 34Fe (i.e., mounted). The heat radiating plate 504 is attached to the both surfaces of the plurality of light-emitting elements 46E or both surfaces via a heat conducting sheet. [Eighth Embodiment] Next, a device according to an eighth embodiment will be described with reference to a schematic cross-sectional view of Fig. 13 . The illuminating device 2G of the eighth embodiment includes a casing chamber 60 having an opening portion 58, a plurality of illuminating portions 32E disposed inside the casing chamber 60, and a cylindrical lens provided in the opening portion 58 of the casing chamber 60 (シy) >Bu, " Lux ky 乂,,: cylindrical lens) 62. The plurality of illumination units 32E are configured in the same manner as in the sixth embodiment described above. Light from the plurality of illumination mechanisms 32E is incident on the cylindrical lens 62, and is bent by a cylindrical lens 62 in a direction close to its optical axis, and is emitted from the cylindrical lens 62, whereby the light from the cylindrical lens 62 is directed toward It is concentrated in a specific area. Further, although not shown, instead of the cylindrical lens 62, a Fresnel lens (7 p 孝 * k V again, ') may be provided in the opening portion 58 of the casing chamber 60. Alternatively, a diffusing plate may be provided in the opening portion 58 of the casing chamber 60. In this case, light from the plurality of illuminating mechanisms 32E is diffused through the diffusing plate, whereby the object to be inspected can be more uniformly illuminated. (not shown) Lighting. In the above, the embodiments of the various illumination devices according to the present invention have been described. However, the present invention is not limited to the embodiments described, and various modifications and changes can be made without departing from the scope of the invention.
