【従来の技術】[Prior art]

テレビカメラ用のＣＣＤ撮像素子は、カメラ本体の前蓋裏面に固定するベース板の裏にマスクを介して取付けられている。この撮像素子の受像面は長方形であり、受像面の長辺を水平（横）にすることによりモニターテレビの画面の映像は正立像になる。一般にテレビカメラ本体は正面から見て長方形で、その長方形の前蓋の表面の中心にレンズが取付き、レンズの奥、つまり前蓋の裏面にＣＣＤ撮像素子が上記のようにして取付けてある。 The CCD image pickup device for a television camera is attached to the back of a base plate fixed to the back of the front lid of the camera body through a mask. The image receiving surface of this image sensor is rectangular, and the image on the monitor TV screen becomes an erect image when the long side of the image receiving surface is horizontal (horizontal). Generally, the main body of a TV camera is a rectangle when viewed from the front, and a lens is attached to the center of the surface of the front lid of the rectangle, and the CCD image pickup device is attached to the inside of the lens, that is, the back of the front lid as described above.

【考案が解決しようとする課題】[Problems to be solved by the device]

従来のテレビカメラは、本体の長方形の長辺を垂直にし、これに受像面の長辺を水平にして撮像素子を取付け、本体と、撮像素子の長辺が直交した縦型と、本体の長方形の長辺と、撮像素子の受像面の長辺とが共に水平で平行な横型の２機種がある。その理由は、例えば工場の生産ラインなどで複数のテレビカメラをセンサーとして使用するとき、図４に示すように縦型同志を隣接した場合のレンズ間のピッチＰ₁ と、横型同志を隣接した場合のレンズ間のピッチＰ₂ は、縦型同志のＰ₁ が狭く、横型同志のＰ₂ はそれよりも広くなり、使用状況に応じどちらかを選択できるようにするためである。そして、縦型（又は横型）の機種の撮像素子を９０°反転して横型（又は縦型）にすることはできないため、それまでセンサーとして複数の縦型を隣接して使用していたのが、生産ラインの変更などで複数の横型を隣接して使用するほうが適する事態が生じると、新たに横型を複数台、購入しなければならない。In a conventional TV camera, the rectangular long side of the main body is made vertical, and the image sensor is attached with the long side of the image receiving surface horizontal, and the main body and the vertical type in which the long sides of the image sensor are orthogonal, There are two types of horizontal type in which the long side of the rectangle and the long side of the image receiving surface of the image sensor are both horizontal and parallel. The reason is that, for example, when using multiple TV cameras as sensors in a factory production line, the pitch P ₁ between the lenses when the vertical comrades are adjacent and the horizontal comrades are adjacent as shown in FIG. In this case, the pitch P ₂ between the lenses is such that the vertical type P ₁ is narrower and the horizontal type P ₂ is wider than that, so that either one can be selected according to the use situation. Since it is not possible to reverse the image sensor of a vertical type (or horizontal type) by 90 ° to make it horizontal type (or vertical type), until then, multiple vertical types were used as adjacent sensors. However, if it becomes more appropriate to use multiple horizontal types next to each other due to changes in the production line, etc., multiple horizontal types must be purchased.

【実施例】【Example】

図示の実施例において、１０は断面が長方形の金属の筒体からなるテレビカメラの本体、１１はその前端を塞ぐ前蓋を示し、前蓋と後蓋は共にアルミダイキャストの成形品で、前蓋には、その中心と同心で、軸方向に貫通した円筒壁１２が一体に成形してあり、該円筒壁１２には、内周で円形マウント穴１３を構成する金属のマウントリング１４が前端から嵌めて固定してあり、レンズの鏡筒１５は円形マウント穴１３の雌ねじにねじ込んで取付けるようになっている。 In the illustrated embodiment, 10 is a main body of a television camera made of a metal cylinder having a rectangular cross section, 11 is a front lid that closes the front end of the television camera. Both the front lid and the rear lid are molded products of aluminum die casting. A cylindrical wall 12 concentric with the center and penetrating in the axial direction is formed integrally with the lid, and a metallic mount ring 14 forming a circular mount hole 13 on the inner periphery is formed in the front end of the cylindrical wall 12. The lens barrel 15 of the lens is mounted by screwing it into the female screw of the circular mount hole 13.

【０００６】上記円筒壁１２の外周には、円周方向に等間隔に離して四つの放射状突出部１６が一体に設けてあり、この各突出部は後向きに開口した盲のねじ孔１７を備えている。又、円筒壁１２の後端には、前記円形マウント穴１３と同心で、円筒壁１２の内周よりも内径が大きい環状***部１８が、円筒壁１２の外周に沿って一体の設けてある。この環状***部１８は、各放射状突出部１６がある個所で途切れた四つの弧状***部により構成してある。On the outer periphery of the cylindrical wall 12, four radial protrusions 16 are integrally provided at equal intervals in the circumferential direction, and each of these protrusions has a blind screw hole 17 which is opened rearward. It is equipped. At the rear end of the cylindrical wall 12, an annular ridge 18 concentric with the circular mount hole 13 and having an inner diameter larger than the inner circumference of the cylindrical wall 12 is integrally provided along the outer circumference of the cylindrical wall 12. is there. The annular ridge 18 is formed by four arc-shaped ridges that are interrupted at the location of each radial protrusion 16.

【０００７】２０は、裏にマスク２１を介してＣＣＤ撮像素子２２を取付けたベース板で、周知のように撮像素子の裏にはプリント配線基板２３が取付けてある。ベース板２０は、前記環状***部１８の内周に嵌合する円形であり、その外周には、ベース板２０を環状***部１８の内周に嵌合したとき、環状***部の途切れた部分１９を通じ各放射状突出部１６に重なる放射状の四つの突起２４が、円周方向に等間隔に設けてあり、この各突起２４はねじ孔１７と連通するビス挿通孔２５を有する。Reference numeral 20 denotes a base plate having a CCD image pickup device 22 attached to the backside thereof via a mask 21, and a printed wiring board 23 is attached to the backside of the image pickup device as is well known. The base plate 20 has a circular shape that fits on the inner circumference of the annular raised portion 18, and when the base plate 20 is fitted on the inner circumference of the annular raised portion 18, the base plate 20 is discontinuous. Four radial projections 24 are provided at equal intervals in the circumferential direction so as to overlap the radial projections 16 through the open portions 19, and each projection 24 has a screw insertion hole 25 communicating with the screw hole 17.

【０００８】前蓋の円筒壁に設けた四つの放射状突出部１６は、上述のようにベース板２０を環状***部１８の内周に嵌合して突起２４を放射状突出部１６に重ねたとき、図１の矢印で示したように撮像素子２２を９０°回し、その長方形の受像面２６の長辺２６´が前蓋の長方形の長辺２０´と直交するか（図１、図３の実線）平行になるか（図１、図３の破線）のどちらかになるように定めてある。従って、ベース板２０の突起２４のビス挿通孔２５にビス２７を挿入し前蓋１１の放射状突出部１６にあるねじ孔１７に締め込むことで撮像素子の受像面の長辺を前蓋の長辺と直交させて（又は平行にして）ベース板２０を前蓋の裏に固定し、前蓋を本体１０の前端に取付けるなどしてメーカーは縦型、横型どちらのテレビカメラも、同じ前蓋と、円形ベース板付き撮像素子を使用して組立てることができる。又、これを購入したユーザーは、前蓋を本体１０から外し、４本のビス２７を抜き、ベース板２０の取付けの向きを９０°反転して再組立てすることにより縦型（又は横型）として購入したテレビカメラを横型（又は縦型）に変えて使用できる。The four radial projections 16 provided on the cylindrical wall of the front lid are formed when the base plate 20 is fitted to the inner circumference of the annular ridge 18 and the projections 24 are superposed on the radial projections 16 as described above. As shown by the arrow in FIG. 1, the image pickup element 22 is rotated 90 ° so that the long side 26 ′ of the rectangular image receiving surface 26 is orthogonal to the long side 20 ′ of the rectangular front lid (see FIGS. 1 and 3). It is defined to be either a solid line) or a normal line (broken line in FIGS. 1 and 3). Therefore, by inserting the screw 27 into the screw insertion hole 25 of the protrusion 24 of the base plate 20 and tightening the screw 27 into the screw hole 17 in the radial protrusion 16 of the front lid 11, the long side of the image receiving surface of the image sensor is fixed. The manufacturer attaches the base plate 20 to the back of the front lid orthogonally to (or parallel to) the long side and attaches the front lid to the front end of the main body 10. It can be assembled using a lid and an image sensor with a circular base plate. Also, the user who purchased this can remove the front lid from the main body 10, remove the four screws 27, reverse the mounting direction of the base plate 20 by 90 ° and reassemble it to make it vertical (or horizontal). You can change the purchased TV camera to horizontal (or vertical) type.

【０００９】勿論、そのためにはプリント配線基板２３も、ベース板２０とほゞ同大の円形にするなど、縦型（又は横型）から横型（又は縦型）に変更するため、ベース板の取付けの向きを９０°反転しても支障なく本体１０の内部に収まるようにしておくことが必要であると共に、プリント配線基板の配線部と、本体１０内の制御部を連絡する電線の長さは充分に長くし、前蓋を外して本体から離し、裏返してベース板の固定用ビス２７に容易にアクセスできるようにする。更に、前蓋の本体前端に対する固定の仕方は任意であるが、これもなるべく容易に着脱できるようにしておくことが好ましい。図示の実施例では前蓋の一方の長辺の両端部にタッピングネジ２８の挿通孔２９を開設し、本体の一方の長辺の両端部にある孔３０にこのネジ２８をねじ込むと共に、前蓋の短辺には本体の二つの短辺の内面に接触する後向きのブラケット３１を設け、本体の各短辺の孔を通してブラケット３１にねじ込んだビス３２で前蓋を本体の前面に固定してある。従って４本のビス２８，３２を外して前蓋を本体から容易に分離できるようにしてある。Of course, for that purpose, the printed wiring board 23 is changed from the vertical type (or the horizontal type) to the horizontal type (or the vertical type) by making the printed wiring board 23 into a circular shape having almost the same size as the base plate 20. It is necessary to keep it inside the main body 10 without any trouble even if the direction of is reversed by 90 °, and the length of the wire that connects the wiring part of the printed wiring board and the control part in the main body 10 Make it long enough and remove the front lid to separate it from the body and turn it over so that the fixing screws 27 of the base plate can be easily accessed. Further, although the method of fixing the front lid to the front end of the main body is arbitrary, it is preferable that the front lid can be attached and detached as easily as possible. In the illustrated embodiment, insertion holes 29 for tapping screws 28 are formed at both ends of one long side of the front lid, and the screws 28 are screwed into holes 30 at both ends of one long side of the main body. On the short side of the lid, a rearward facing bracket 31 that contacts the inner surfaces of the two short sides of the main body is provided, and the front lid is fixed to the front surface of the main body with screws 32 screwed into the bracket 31 through the holes of each short side of the main body. is there. Therefore, the four screws 28 and 32 are removed so that the front lid can be easily separated from the main body.

【考案の効果】[Effect of device]

以上で明らかなように本考案によれば、メーカーは同じ前蓋と、円形ベース板付き撮像素子を用い、縦型、横型どちらのテレビカメラも製造できる。従って、縦型のテレビカメラと、横型のテレビカメラを別々の部分で組立てる場合にくらべ、部品の使用点数は少なくなり、部品の管理も容易である。又、ユーザーは、縦型（又は横型）を購入して使用中、必要に応じそれを横型（又は縦型）に変えて使用できるため、前の縦型（又は横型）の使用を止め、新しく横型（又は縦型）を購入する無駄が無くなる。 As is clear from the above, according to the present invention, the manufacturer can manufacture both vertical and horizontal TV cameras by using the same front lid and the image pickup device with the circular base plate. Therefore, compared to the case where the vertical TV camera and the horizontal TV camera are assembled in separate parts, the number of parts used is smaller and the management of the parts is easier. Also, the user can purchase the vertical type (or horizontal type) and use it while changing it to the horizontal type (or vertical type) as needed, so stop using the previous vertical type (or horizontal type) There is no waste of purchasing a horizontal type (or a vertical type).
