本願は製版カメラの光源アーム装置の改良に関する発明
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a light source arm device for a plate-making camera.
製版カメラの光源は、従来においては、屈曲を自在にな

出ているために作業の邪魔となりその都度避けるべく、
アームを動かし、撮影時にまたもとに戻すという煩雑な
操作を繰り返すのが一般であつた。Conventionally, the light source of a prepress camera was attached to a bendable arm, and the position and angle could be adjusted. In order to avoid it each time,
It was common to repeat the complicated operation of moving the arm and returning it to its original position when shooting.
本願発明は上述の事情に鑑み開発されたもので、アーム

供を目的としたものである。The present invention was developed in view of the above-mentioned circumstances, and aims to provide a light source device with excellent accuracy and precision by making special improvements to the structure of the arm to eliminate the defects described above without interfering with work. That is.

に本願アーーム装置を設けた場合につき例示するもので
ある。The light source arm device according to the present application will be described in detail below. Its configuration is such that an L-shaped arm support 4 is extended from the support base 3 of the document frame 2 along the side of the document frame 2, and the upper side of the document frame A connecting rod 5 is rotatably connected in a horizontal plane from the tip of the rod 4 located in the center, and an arm rod 6 is slidably installed horizontally on the connecting rod 5, and a lamp T is attached to the connecting rod 5. The present invention is characterized by a rotary light source arm device for a prepress camera, in which vertical rods 8 are slidably attached to both sides of the arm rod 6. The drawing is rotated using a floor-type plate-making camera 5. The support stand 3 for the manuscript frame 2'
The following is an example of a case where the arm device of the present application is provided.

成は叙上の如くであり、その構成５ から次の様な効果
が生ずる。In the figure, numeral 9 indicates a plate-making lens, and numeral 10 indicates a photographing section. Also, Figure 1 shows the configuration when photographing with a reflective light source such as an original drawing, and Figure 2 shows the configuration when photographing with a transmitted light source such as film.
The figures are shown in case of shadows. In the latter case, the connecting rod 5 is rotated 180 degrees, and the vertical rod 8 is further slid inward to bring it closer to the optical axis. The structure of the present invention is as described above, and the following effects are produced from the structure 5.
垂杆８におけるランプ１の取付位置及び角度、またアー
ム杆６における垂杆８の位置、更らに連杆５におけるア
ーム杆６の位置は一度適正にしておけば連杆５を回動し

を保持できるから従来の屈曲アームタイプのものに比し
、再調整は不要であり、かつ回動方式であるから原稿さ
し込み作業時にランプを容易に退けうるものであり、作
業性は格段に向上する。Once the mounting position and angle of the lamp 1 on the vertical rod 8, the position of the vertical rod 8 on the arm rod 6, and the position of the arm rod 6 on the connecting rod 5 are properly set, you can adjust the position and angle after rotating the connecting rod 5. , since it can maintain the proper position and angle when returned to its original state, there is no need for readjustment compared to the conventional bending arm type, and since it is a rotating type, the lamp can be used when inserting documents. can be easily eliminated, and work efficiency is greatly improved.
５ また反射及び透過両用の光源として使用できるから
それぞれ専用ランプを用意することなく至つて経済的で
ある。5. Also, since it can be used as a light source for both reflection and transmission, it is extremely economical without having to prepare dedicated lamps for each.
殊にカラー撮影の場合フィルターのさし換え等作業工数
の多い場合においてその効果は多大である。The effect is particularly great when color photography requires a lot of man-hours, such as replacing filters.
以上本願発明につき詳説したが本案は目的において斬新
