う。This type of exposure device has a configuration in which a point light source illuminates the entire surface of the document, and the light that has passed through the document simultaneously exposes the entire exposed surface of the photosensitive material. A filter is placed on the optical path to adjust the color of the light.

となり、感光材料上に得られる画像の色むらや濃度むら
を完全になくすようにするのはかなり困難であった。Devices that expose photosensitive materials using such a surface exposure method have the advantage of requiring only one exposure, but in order to obtain a homogeneous and clear image, it is necessary to uniformly illuminate a wide area of the document. For this purpose, means such as an illumination system, an imaging optical system, and a filter for color adjustment are required, and the exposure device becomes large, and it is difficult to completely eliminate color unevenness and density unevenness in the image obtained on the photosensitive material. was quite difficult.

露光可能な露光装置を提供することにある。An object of the present invention is to solve the above-mentioned problems, and by using a simple and compact configuration, it is possible to expose an image in the form of a light-transmissive manuscript onto a bright light material without causing color unevenness or density unevenness. The purpose of the present invention is to provide an exposure apparatus that can be used.

えた露光装置によって達成される。[Means and effects for solving the problem] The above-mentioned object of the present invention is to provide an exposure device that exposes a bright light material with light transmitted through a light-transmissive original, which includes a rod-shaped light source and a light source that collects light from the light source. A light reflecting plate that emits light, a filter that adjusts the color tone of the light from the light source, a diffusion means that diffuses the light that has passed through the filter and guides it to the document, and a slit that is parallel to the rod-shaped light source to reflect the light that has passed through the document. This is achieved by an exposure apparatus equipped with a slit member that guides the photosensitive material toward the photosensitive material, and a conveying means that synchronously conveys the document and the photosensitive material.

できる。In other words, since the light-transmissive original and the photosensitive material are transported synchronously and the photosensitive material is slit-exposed, there is no need for a means to move the optical system, and the exposure device becomes larger like a surface exposure device. There's nothing to do. Further, by disposing a filter on the optical path of the light from the light source before it reaches the document, it is easy to adjust the color of the light. Further, since the light source is rod-shaped corresponding to the slit, the amount of light passing through the slit can be made uniform across the slit direction, and the photosensitive material can be exposed without causing color unevenness or density unevenness.

る。The light from the rod-shaped light source 72 passes through an optical path covered by a long-focus reflector 73 until it reaches the upper end of the diffusion means 75, that is, the second focal point.Moreover, since the configuration is such that the reflecting mirror 80 in FIG. 2 is omitted, the rod-shaped light source The light from 72 effectively reaches the diffusion means 75, and loss of light amount can be prevented.

る。According to the present invention, since the light-transmissive original and the photosensitive material are synchronously conveyed and the photosensitive material is slit-exposed,
A means for moving the optical system is not required, and the exposure apparatus does not become larger unlike a surface exposure apparatus. Further, by disposing a filter on the optical path of the light from the light source before it reaches the document, it is easy to adjust the color of the light. Furthermore, since the light source is rod-shaped and corresponds to the slit, the amount of light passing through the slit is uniform in the direction of the slit, and the photosensitive material can be exposed without causing color unevenness or density unevenness.

置。An exposure device that exposes a photosensitive material to light that has passed through a light-transmitting original includes a rod-shaped light source, a reflector that collects the light from the light source, a filter that adjusts the color tone of the light from the light source, and a light that passes through the filter. a slit member that has a slit parallel to the rod-shaped light source and guides the light that has passed through the original toward the photosensitive material; and a conveyor that synchronously transports the original and the photosensitive material. An exposure apparatus comprising means.
