あった。However, it is necessary to electrically change the amount of light emitted from the light emitting means per unit time or the light emitting time according to each image forming means. Since it is necessary to incorporate conditions such as the amount of emitted light per unit of time and light emission time as data, the soft capacity increases and a mechanism for adjusting the resistance value is required,
There was a problem that it was costly. There is also a problem that data cannot be imprinted on a plurality of positions at the same time.

And a plurality of image forming means for forming an image of a light beam from the light emitting means on a film surface at a plurality of positions on the film surface. The problem is solved by changing the effective diameter of each image-forming means in accordance with the distance from the light-emitting means to the incident surface of each image-forming means to make the numerical aperture on the object side substantially constant.

の明るさを一定にすることであり、物体側開口数ＮＡを
一定にすれば良い。With the above structure, the present invention can obtain proper exposure. The description will be given below. Generally, when a light beam emitted from an object point on the optical axis on the object plane is incident on the imaging lens, the object-side numerical aperture NA indicating the brightness of the imaging lens has an inclination angle of the axial light beam of θ and an image formation. NA = 2n sin θ, where n is the refractive index of the medium on the object side of the lens. Further, obtaining the proper exposure is to make the brightness of the imaging lens constant, and the object side numerical aperture NA may be made constant.
【０００７】ところで、本発明においては、結像手段の

の最も物体側の面の有効径をＤ、物体面から結像手段の
最も物体側の面までの距離をＬとすれば、 tan θ＝Ｄ／Ｌ ・・・・(A) で表される。By the way, in the present invention, since the effective light flux is determined by the surface of the image forming means closest to the object side, the effective diameter of the surface of the image forming means closest to the object side is D, and the effective surface of the image forming means is changed from the object surface to the image forming means. If the distance to the surface closest to the object is L, then tan θ = D / L ... (A)
【０００８】よって、(A) 式においてＤ／Ｌを一定にす
れば、物体側開口数ＮＡも一定となり、適正露出を得る

結像手段の入射面までの距離に応じた有効径にすれば、
物体側開口数を一定にすることができ、適正露出を得る
ことができる。Therefore, if D / L is made constant in the equation (A), the object-side numerical aperture NA will also become constant, and proper exposure can be obtained. Further, from the formula (A), the longer the distance L from the object plane to the most object-side surface of the image forming means,
It can be seen that the effective diameter D also increases. Therefore, in the present invention, if the effective diameter at the incident surface of the image forming means is set to an effective diameter corresponding to the distance from the light emitting means to the incident surface of each image forming means,
The object-side numerical aperture can be made constant, and proper exposure can be obtained.
