Description
【０００１】[0001]
この考案は、ルーフミラーに関する。 This invention relates to a roof mirror.
【０００２】[0002]
複写機の露光装置やファクシミリの原稿走査装置にはルーフミラーが用いられ るものが多い。このルーフミラーは、１対の平面鏡を、鏡面が所定の角を成すよ うに組み合わせて一体化して構成されたものであって、原稿から光導電性感光体 や撮像素子に到る光路を屈曲させるのに用いられる。 Roof mirrors are often used in exposure devices of copying machines and document scanning devices of facsimiles. This roof mirror is constructed by combining a pair of flat mirrors so that the mirror surfaces form a predetermined angle, and bends the optical path from the document to the photoconductive photoconductor or the image sensor. Used to.
【０００３】 特に良く用いられるルーフミラーは原稿走査用であって、ランプと一体になっ て原稿面を走査する走査ミラーからの光束を結像レンズ系に向けて折り返して反 射し、走査ミラーと同方向へ走査ミラーの１／２の速さで移動して、原稿面から 結像レンズ系に到る光路長を不変に保つものである。A roof mirror that is particularly often used is for scanning an original, and a light beam from a scanning mirror that scans the surface of the original with a lamp is folded back toward an imaging lens system to reflect the light. It moves in the same direction at half the speed of the scanning mirror to keep the optical path length from the document surface to the imaging lens system unchanged.
【０００４】 このようなルーフミラーは、一般に、１対の平面鏡の両端部を１対の支持体で 支持して構成される。各平面鏡端部の支持は従来、図３にように行われていた。 図３において、符号１は、２面の平面鏡Ｍ１，Ｍ２の一方の端部をそれぞれ支持 する支持部材を示している。支持部材１は、平面鏡支持用の支持孔１Ａ，１Ｂと 調整孔１Ｃとを穿設されている。Such a roof mirror is generally configured by supporting a pair of flat mirrors at both ends thereof with a pair of supports. Conventionally, the support of each flat mirror end is performed as shown in FIG. In FIG. 3, reference numeral 1 indicates a support member that supports one end of each of the two-faced plane mirrors M1 and M2. The support member 1 is provided with support holes 1A and 1B for supporting a plane mirror and an adjustment hole 1C.
【０００５】 支持孔１Ａには、調整孔１Ｃの側から１対の調整ねじ３Ａが螺装され、その先 端部は支持孔１Ａ中に突出している。また支持孔１Ａには、調整ねじ３Ａと対向 するように板バネ４Ａが設けられている。支持孔１Ｂには、支持孔１Ａにおける と全く同様にして、１対の調整ねじ３Ｂと板バネ４Ｂが設けられている。A pair of adjusting screws 3A is screwed into the supporting hole 1A from the adjusting hole 1C side, and the tip end thereof projects into the supporting hole 1A. Further, a leaf spring 4A is provided in the support hole 1A so as to face the adjusting screw 3A. The support hole 1B is provided with a pair of adjusting screws 3B and a leaf spring 4B in the same manner as in the support hole 1A.
【０００６】 平面鏡Ｍ１は、その端部を支持孔１Ａに侵入させて、鏡面側を調整ねじ３Ａの 側にして背面側から板バネ４Ａにより調整ねじ３Ａの先端部に押しつけられる。 このように、平面鏡Ｍ１は調整ねじ３Ａと板バネ４Ａにより支持部材１に支持さ れる。全く同様にして、平面鏡Ｍ２は調整ねじ３Ｂと調整ねじ４Ｂとにより支持 部材１に支持される。平面鏡Ｍ１，Ｍ２の他方の端部も同様にして支持される。 調整ねじ３Ａ，３Ｂにより、平面鏡Ｍ１，Ｍ２のなす角が所定の角となるように 調整する。この他、支持部材自体を所定の軸の周りに揺動可能とし、上記軸に対 する支持部材の態位を調整して平面鏡相互のなす角を調整する方法も行なわれて いる。The flat mirror M1 has its end portion inserted into the support hole 1A and is pressed against the tip end portion of the adjusting screw 3A by the leaf spring 4A from the back side with the mirror surface side facing the adjusting screw 3A. Thus, the plane mirror M1 is supported by the support member 1 by the adjusting screw 3A and the plate spring 4A. The plane mirror M2 is supported by the support member 1 by the adjusting screws 3B and 4B in exactly the same manner. The other ends of the plane mirrors M1 and M2 are similarly supported. The adjustment screws 3A and 3B are used to adjust the angles formed by the plane mirrors M1 and M2 so that the angles become a predetermined angle. In addition, a method is also used in which the support member itself can be swung around a predetermined axis, and the position of the support member with respect to the axis is adjusted to adjust the angle between the plane mirrors.
【０００７】 このように、従来の平面鏡支持は、第１に支持部材の構造が複雑であり、第２ に平面鏡支持作業が「平面鏡相互のなす角を調整する作業」を含むため、ルーフ ミラーの組立て能率が悪く、さらに、原稿走査走査用に用いられて移動させられ るような場合には、各平面鏡の支持態位に、振動等により経時的な狂いが生ずる 問題もあった。As described above, in the conventional flat mirror support, firstly, the structure of the support member is complicated, and secondly, the flat mirror support work includes "the work of adjusting the angle formed by the flat mirrors", and therefore, When the assembling efficiency is low, and further, when the original is used for scanning and scanning the original to be moved, the supporting state of each plane mirror has a problem that it is distorted with time due to vibration or the like.
【０００８】[0008]
この考案は上述した事情に鑑みてなされたものであって、構造簡素で組立てが 容易であり、組み立て後の平面鏡の支持態位に狂いが生じにくい、新規なルーフ ミラーの提供を目的とする。 The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide a novel roof mirror which has a simple structure, is easy to assemble, and is less likely to cause an error in the support position of the assembled flat mirror.
【０００９】[0009]
この考案のルーフミラーは、「１対の平面鏡を、鏡面が所定の角を成すように 組み合わせて一体化して」なるルーフミラーであって、１対の平面鏡と、１対の 支持部材と、固定手段とを有する。 The roof mirror of the present invention is a roof mirror formed by "combining a pair of plane mirrors so that the mirror surfaces form a predetermined angle and integrating them", and a pair of plane mirrors, a pair of support members, and a fixed member. And means.
【００１０】 「１対の平面鏡」は、所定の角をなして屋根型に組み合わせられる。各平面鏡 は、金属板の表面を鏡面としたものや、金属やガラス、あるいはプラスチック等 の板に反射膜を形成したものを用いることができる。表面鏡の場合は、鏡面に保 護膜を形成しても良い。平面鏡の厚さは任意である。 「１対の支持部材」は、上記１対の平面鏡を両端部で支持する。 「固定手段」は、各平面鏡端部を各支持部材に固定する。The “pair of plane mirrors” are combined in a roof shape with a predetermined angle. As each plane mirror, a metal plate having a mirror surface or a plate made of metal, glass, plastic, or the like having a reflection film formed thereon can be used. In the case of a surface mirror, a protective film may be formed on the mirror surface. The thickness of the plane mirror is arbitrary. The "pair of support members" support the pair of flat mirrors at both ends. The "fixing means" fixes each flat mirror end portion to each support member.
【００１１】 上記１対の支持部材のそれぞれには「各平面鏡の両端部の鏡面部（表面鏡の場 合は鏡面と同一面、裏面鏡の場合は平面鏡の表面）が面接触する支持面が所定の 角（鏡面が相互になすべき角）をもって」形成されている。Each of the pair of support members has a support surface with which “the mirror surface portions at both ends of each flat mirror (in the case of a front surface mirror, the same surface as the mirror surface, and in the case of a back surface mirror, the surface of the flat mirror) are in surface contact. It is formed with a predetermined angle (corner where the mirror surfaces should be mutually).
【００１２】 上記固定手段は「接着」でも良いし（請求項２）、支持部材に設けられて平面 鏡の背面側から平面鏡を支持部材の支持面に向かって押しつける「板バネ」であ ってもよい（請求項３）。The fixing means may be “adhesion” (Claim 2), or a “leaf spring” which is provided on the support member and presses the flat mirror from the rear side of the flat mirror toward the support surface of the support member. (Claim 3)
【００１３】[0013]
この考案では、平面鏡端部は両端部の鏡面部が支持面に面接触した状態で支持 部材に固定されるが、支持面は互いに所定の角（鏡面同士が成すべき角）をもっ て形成されているから、平面鏡対は１対の支持部材に固定されると、自動的に所 定の角をなすルーフミラーとして完成する。 In this invention, the flat mirror ends are fixed to the support member in a state where the mirror surface portions at both ends are in surface contact with the support surfaces, but the support surfaces are formed at predetermined angles (angles between the mirror surfaces). Therefore, when the flat mirror pair is fixed to the pair of supporting members, the flat mirror pair automatically completes as a roof mirror having a predetermined angle.
【００１４】[0014]
以下、具体的な実施例を説明する。 Specific examples will be described below.
【００１５】 図１（ａ）において、符号Ｍ１，Ｍ２は図３におけると同じく平面鏡を示す。 これら平面鏡Ｍ１，Ｍ２は長方形形状であり、長手方向を互いに平行にし、所定 の角を成して１対の支持部材１０，２０により一体化されている。支持部材１０ ，２０は板状であって「全く同一の形状」であり、図１（ｂ）に例示する支持部 材１０のように、平面鏡Ｍ１，Ｍ２の鏡面側の面を、各平面鏡長手方向両端部に おいて面接触状態で支持する支持面１０Ａ，１０Ｂが「厚み部分」に形成されて いる。これらの支持面１０Ａ，１０Ｂの成す角：θは平面鏡Ｍ１，Ｍ２が成すべ き角に精度よく仕上げられており、従って、平面鏡Ｍ１，Ｍ２の端部を図１（ｂ ）のように、支持面１０Ａ，１０Ｂに面接触させるのみで、平面鏡Ｍ１，Ｍ２は 成すべき角：θを自動的に形成することになる。In FIG. 1A, reference numerals M1 and M2 indicate plane mirrors as in FIG. These plane mirrors M1 and M2 have a rectangular shape and have their longitudinal directions parallel to each other and are integrated by a pair of supporting members 10 and 20 at a predetermined angle. The support members 10 and 20 are plate-shaped and have “exactly the same shape”. As in the supporting member 10 illustrated in FIG. Supporting surfaces 10A and 10B, which are supported in surface contact at both ends in the direction, are formed in "thickness portions". The angle θ formed by these supporting surfaces 10A and 10B is accurately finished to the angle formed by the plane mirrors M1 and M2. Therefore, the ends of the plane mirrors M1 and M2 are supported as shown in FIG. 1 (b). The plane mirrors M1 and M2 automatically form the angle θ to be formed by merely making surface contact with the surfaces 10A and 10B.
【００１６】 この実施例では、平面鏡Ｍ１，Ｍ２を１対の支持部材にそれぞれ固定する固定 手段は「接着」である。即ち、平面鏡Ｍ１，Ｍ２は、それぞれ所定の支持面に面 接触状態で接着される。このようにして、平面鏡Ｍ１，Ｍ２と一対の支持部材１ ０，２０は一体化され、図１（ａ）に示すようなルーフミラーが得られる。In this embodiment, the fixing means for fixing the plane mirrors M1 and M2 to the pair of supporting members is “adhesion”. That is, the plane mirrors M1 and M2 are adhered to a predetermined supporting surface in surface contact with each other. In this way, the plane mirrors M1 and M2 and the pair of support members 10 and 20 are integrated, and a roof mirror as shown in FIG. 1A is obtained.
【００１７】 図２には変形実施例を示す。１対の支持部材は互いに全く同じ形状であり、図 ２には一方の支持部材１２が例示されている。平面鏡Ｍ１，Ｍ２は長手方向両端 部の鏡面部を、支持部材１２の支持面１２Ａ，１２Ｂに面接触させられ、板バネ １３Ａ，１３Ｂにより、背面側から支持面１２Ａ，１２Ｂに押しつけられて固定 させる。板バネ１３Ａ，１３Ｂは支持部材１２に「ねじ」で固定されている。支 持面１２Ａ，１２Ｂは勿論、平面鏡Ｍ１，Ｍ２がなすべき角をもって形成されて いる。FIG. 2 shows a modified embodiment. The pair of support members have exactly the same shape, and one support member 12 is illustrated in FIG. The plane mirrors M1 and M2 have their mirror surfaces at both ends in the longitudinal direction brought into surface contact with the support surfaces 12A and 12B of the support member 12, and are fixed by being pressed against the support surfaces 12A and 12B from the back side by the leaf springs 13A and 13B. .. The leaf springs 13A and 13B are fixed to the support member 12 with “screws”. The supporting surfaces 12A and 12B are of course formed with the corners that the plane mirrors M1 and M2 should form.
【００１８】[0018]
以上のように、この考案によれば新規なルーフミラーを提供できる。このルー フミラーは、平面鏡を支持部材の支持面に面接触させた状態で支持部材に固定す るのみで、平面鏡間のなす角が実現されるので組立てが容易であり、支持体と平 面鏡の関係が面接触状態であるから、振動等によっても平面鏡相互のなす角に狂 いが生じにくい。 As described above, according to this invention, a new roof mirror can be provided. This roof mirror is easy to assemble because the angle between the plane mirrors can be realized only by fixing the plane mirror to the support surface while the plane mirror is in surface contact with the support surface of the support member. Since the relation of is a surface contact state, the angle formed by the plane mirrors is unlikely to be deviated due to vibration or the like.
