光長があるので主露光長方向に沿った長尺平面ミラーを
備えている。Exposure devices such as image forming apparatuses often use reflective mirrors to reflect and guide light from a light source toward a photosensitive material. In particular, a slit exposure device or a surface exposure device has a main exposure length, so it is equipped with a long plane mirror along the main exposure length direction.
ミラー固定装置として、例えば実公昭５９−１６８８４

する手段とを備えた構成である。This device includes a first plate body having a cut surface having one protrusion formed by press cutting, and a second plate body having a cut surface having two protrusions formed by press cutting. A plate body, means for holding the first and second plate bodies at a distance, and a plane mirror provided on the one protrusion of the first plate and the two protrusions of the second plate. This configuration includes elastic pressing means.

性高く保持することができない。However, the device described in the above publication is difficult to manufacture because the punched shape is complicated. Furthermore, if the edges of the processed edge are in contact with the mirror, stress concentration may occur and the mirror may be damaged. Moreover, the mirror is not prevented from moving in the longitudinal direction, so there is less friction between the metal and the mirror.
The mirror cannot be held reliably because it vibrates or slides.

材とを備えたミラー固定装置によって達成される。[Means and Effects for Solving the Problems] The above object of the present invention is to provide a pair of plastic resin mirror fixing devices that are attached to opposing notches formed in opposing mirror fixing walls and that fix opposing ends of a plane mirror. The members include a support member that abuts one surface of the mirror, a first elastic member that abuts a longitudinal end surface of the mirror and urges the mirror toward the opposite end surface, and a first elastic member that abuts the other surface of the mirror and the mirror fixing wall. This is achieved by a mirror fixing device including a second elastic member supported by the notch edge of the mirror and biasing the mirror against the support member.

Since the elastic member restricts the movement of the mirror in the thickness direction,
The mirror is securely fixed. Further, since the mirror fixing member is made of plastic resin, it can increase the frictional resistance with the mirror, and can prevent vibration and sliding of the mirror. Moreover, since the mirror fixing members are simply attached to opposing notches formed in the opposing mirror fixing walls, the mirror can be easily fixed.

ー固定部材２の脱落が防止される。The mirror fixing wall 18 has a support member 6 for the mirror fixing member 2.
A rectangular notch 20 into which the second elastic member 14 can be inserted is formed. Note that the length of the notch 20 in the mirror width direction (not indicated by arrow Z) is slightly longer than the width of the mirror 60. Furthermore, a locking hole 22 is formed in the vicinity of the notch 20 in the mirror fixing wall 18, into which the locking protrusion 16 for preventing the mirror fixing member 2 from falling off is locked. The locking hole 22 has a size that allows the locking protrusion 16 to be inserted therethrough. The mirror fixing member 2 has a notch 20 in which the support member 6 and the second elastic member 14 are formed.
The mirror is attached to the mirror fixing wall 18 so as to be in contact with the opposing edges 2Qa and 2Qb. Further, by inserting the locking protrusion 16 of the mirror fixing member 2 into the locking hole 22 and locking it by the edge of the hole, the mirror fixing member 2 is prevented from falling off. Further, by providing a step 24 that is engaged with the mirror fixing wall 18 at the portion of the second elastic member 14 that contacts the notch 20, the mirror fixing member 2 is prevented from falling off.

る。The mirror 8 fixed by the mirror fixing member 2 has a first elastic member 12 in contact with its longitudinal end face, urging the mirror 8 toward the center in the longitudinal direction. The longitudinal position of the mirror 8 is limited by biasing both end faces in the longitudinal direction. Further, two protrusions 10 of the support member 6 are in contact with the back surface of the mirror 8, and a second elastic member 14 is in contact with the reflective surface of the mirror 8, urging the mirror 8 against the protrusions 10. .

１８に装着する。After one end of the mirror 8 is fixed as described above, the other end is fixed in the same manner. At that time, the end of the mirror 8 is inserted into the notch 20 of the mirror fixing wall 18 in advance, and then the other end is fixed in the same manner. A mirror fixing member is attached to the end of the mirror 8 and the mirror fixing wall 18.

数が高く、ミラー８の滑りが防止される。The mirror 8 fixed to the mirror fixing wall 18 by the pair of mirror fixing members 2 is restricted from moving in the longitudinal direction by the pair of first elastic members 12, and by the protrusion 10 of the support member 6 and the first elastic member work 2. Since movement in the thickness direction is regulated, and movement in the width direction is substantially regulated by the notch 20, the mirror 8 is reliably fixed without causing vibration. Also,
Support member 6 and each elastic member 12, 14 in contact with mirror 8
Since it is made of plastic resin, it has a high coefficient of friction with the mirror 8 and prevents the mirror 8 from slipping.
また、ミラー８の滑り防止のために、各弾性部材１２．
１４及び突起１０のミラー８との接触部に、高摩擦部材
を設けてもよい。In addition, each elastic member 12. is provided to prevent the mirror 8 from slipping.
14 and the protrusion 10 may be provided with a high friction member at the contact portion with the mirror 8.
更に、ミラー固定位置は支持部材６の厚みと突起１０の
高さとの和（図中Ｌ）で規定されるが、Ｌが設計通りに
なるように成形することは容易であるので、高精度の固
定位置が保証される。Furthermore, the mirror fixing position is defined by the sum of the thickness of the support member 6 and the height of the protrusion 10 (L in the figure), but since it is easy to mold so that L is as designed, high precision Fixed position is guaranteed.
また、ミラー８は幅方向に沿ってわずかに移動可能であ

Even if the mirror 8 moves in the width direction, the mirror 8
Since the reflecting surfaces of are on the same plane, the reflected optical path is not changed.

ラー幅方向にミラー８を付勢する第３弾性部材２６を有
する点で第３図に示す構成と異なる。The mirror fixing member 2 shown in No. 5'rA differs from the structure shown in FIG. 3 in that it includes a third elastic member 26 that biases the mirror 8 in the mirror width direction shown by arrow Z.

方向の移動が規制される。The third elastic member 26 is, for example, a plate spring that is cantilevered by the support member 6, and has a shape in which the free end of the plate spring is inverted and curved, and the curved portion also produces elasticity. This third elastic member 26 comes into contact with the end face of the mirror 8 in the width direction, and biases the mirror 8 against the notch edge 20c of the mirror fixing wall 18 facing the third elastic member 26. Therefore, movement of the mirror 8 in the width direction is restricted.
本変形例によれば、ミラー８は長手方向、厚み方向及び
幅方向の移動を規制されるので、ミラー８を確実に固定
することができる。According to this modification, the movement of the mirror 8 in the longitudinal direction, thickness direction, and width direction is restricted, so that the mirror 8 can be reliably fixed.

It can be of any shape. Furthermore, an elastic material such as rubber may be used instead of the leaf spring.

For example, the first elastic member 12 and the second elastic member 14 may be provided on the support member 6 of the mirror fixing member 2. Further, the third elastic member 26 may be provided on the base 4.
