た。 These lamps require careful handling when they are replaced due to failure or deterioration over time, making the replacement work complicated. For example, when replacing an exposure lamp, it is necessary to remove the exposure unit, which has an optical system as a whole, from the copying machine, complete the replacement work outside the copying machine, and then reattach the exposure unit to the copying machine. In another copying machine, the input terminal member that supplies current to the lamp and holds the lamp is removed, and then the lamp is removed, but in this case, not only is it troublesome to remove the lamp, but also When installed, the lamp position often shifts, resulting in the disadvantage that uniformity of illumination cannot be guaranteed.

る。 In order to achieve this objective, according to the present invention,
In a lamp holding mechanism for a long and narrow copying machine in which both ends are held in contact with each other by a terminal member, thereby enabling electricity to flow, a hollow guide portion is provided around the lamp end of one terminal member provided on the back side of the copying machine. The hole in this guide part is formed so that the entrance part is larger than the diameter of the lamp and gradually narrows toward the back. The one terminal member extends toward the entrance portion, and the terminal member on the opposite side of the one terminal member and on the front side of the copying machine holds the lamp in pressure contact with both terminal members. Thus, there is provided a lamp holding mechanism comprising an elongated arm-shaped member made of an elastic conductive material, the arm portion of the opposite terminal member being movable to release the lamp from pressure contact. Accordingly, when removing the lamp, by pulling one of the terminal members in the opposite direction to the pressure contact, the lamp is released from being held and the lamp can be taken out from the copying machine. Also, when installing a new lamp, one end of the lamp is gradually inserted from the entrance of the hollow hole of the guide member, so that one end of the lamp comes into contact with one terminal member,
In this state, the other end of the lamp is held and pressed into contact with another terminal member, which is a simple operation. During installation, the position of the terminal member does not change, thus ensuring that the position of the lamp is in its proper position during manufacturing and assembly.

例を説明するが他のランプでも同様に適用でき
る。 This copying machine 1 is provided with an exposure unit 5 including an exposure lamp 3 and a lens group 4 that illuminate an original placed on a moving platen 2, and projects an optical image of the original onto a photoreceptor 6. An electrostatic latent image is formed on the surface of 6. The lamp 3 is an elongated glass tube that can emit light over its length depending on the width of the document or the width of the photoreceptor 6, and its removal and installation must be done with care. This is troublesome, and furthermore, misalignment during installation causes uneven illumination and deteriorates the quality of copied images. The present invention solves these problems. Hereinafter, embodiments of the present invention will be described using the exposure lamp 3 as a representative, but the present invention can be similarly applied to other lamps.

One of them is provided with a hollow guide member 17 at the tip 13 which presses against the end of the lamp. The hollow hole 18 of this guide member 17 is wide open at its entrance portion 19, and gradually narrows toward the back 20 where the bent end 13 of the terminal 12 extends into the hole. In the drawing, the entrance of the hollow hole 18 is formed wide for convenience of illustration, but it may be made narrower as long as it is larger than the diameter of the lamp so that the lamp 3 can be inserted therein. This guide member 17 has a flange 21 formed on the side thereof, and this flange 21 is fixed to a frame 22 of the copying machine, etc., and the entrance portion 19 of the hole of the guide member 17 is connected to a reflector plate 23 ( (See also FIG. 1) (see FIG. 4). Guide member 1
7 is made of an insulating material such as synthetic resin, and terminal member 12

空孔に挿入する方法もある。 By configuring the lamp holding mechanism as described above, the lamp 3 can be removed and attached very easily. When removing the lamp 3, as shown in FIG. 2, by holding the handle portion 24 and bending one terminal member 12 in the direction of arrow A, the lamp 3 is no longer held by the tip portion 13 and can be easily removed. In this case, in the copying machine shown in FIG. 1, it can be taken out from above. Next, when installing a new lamp, first attach one end of the lamp to the guide member
When pushed inward from the entrance portion 19 of the hollow hole 18 of 7, the terminal member 12 extends to the back 20.
In this state, hold the handle part 24 of the other terminal member 12 and bend it once to remove the tip part 1.
3 to the end of the lamp 3, the lamp can be easily reattached. Other mounting methods include the third
As shown in the figure, there is also a method of inserting the other lamp end 11 into the hollow hole of the guide member 17 while pressing the end 11 of the lamp 3 against the tip 13 of the terminal member 12 provided with the handle portion 24.

る。 As described above, the lamp holding mechanism according to the present invention allows the lamp to be removed and installed very easily. If the lamp is used in a copying machine as shown in FIG.
By providing the terminal member 12 with the guide member 17 on the front side of the copying machine and the terminal member 12 provided with the guide member 17 on the back side, the advantage is that workers such as maintenance personnel can install and remove the lamp only from the front side of the copying machine. There is also. Furthermore, since the terminal member 12 is fixed to the copying machine, even if the lamp is removed and a new lamp is installed, the lamp position will not change and will be placed at the appropriate position adjusted at the time of manufacture. This eliminates the problem of uneven lighting associated with lamp replacement work.

を得ることができる。 In the above embodiment, the guide member and the mounting member for the terminal member attached to the guide member are shown as separate bodies, but they may be formed as one piece. In this case, the terminal member on the guide member side does not need to have elasticity, and pressure contact can be achieved by the elasticity of the other terminal member.
