一定に保つとか、又はフラツシユバルブを使用し
てその閃光を利用するとかの方法が採られてい
る。(Prior art) Conventionally, in a thermal plate making device, it is necessary to control the light beam emitted by the heat source lamp to the required amount, so the heat source lamp is equipped with a timer to keep the irradiation time constant, or a flash valve is set. The method of using it and utilizing the flash is adopted.
（発明が解決しようとする問題点）
そして特にフラツシユバルブを使用する場合は
フラツシユを直接至近距離で照射するとランプに
近い部分が高温になりその周辺部がやや低温にな
つて温度差が生じそのため均一な原版が作成でき
なくなる弊があつた。(Problem to be solved by the invention) Particularly when using a flash bulb, if the flash is irradiated directly at close range, the part near the lamp will become hot, and the surrounding area will become slightly colder, creating a temperature difference. This had the disadvantage that it was not possible to create a uniform original plate.
本発明は斯る欠点を解消し、フラツシユバルブ
を用いても均一な光線が感熱原紙に照射されてム

提供を目的とする。 It is an object of the present invention to provide a thermal plate-making apparatus which eliminates such drawbacks and can produce a printing original plate without unevenness by irradiating a thermal printing paper with a uniform light beam even when a flash valve is used.

It has a series of hollow recesses 4 in the upper part, a reflecting mirror 5 is stretched on the inner surface thereof, and a transparent plate 6 is provided.
A thermal plate-making device 8 is constituted by a press table 7 supported on the base 3 so as to be able to come into contact with the upper surface of the pedestal 1.

The parallel light beams that enter the cavity and are reflected by the reflecting mirror 5 stretched on the inner surface of the hollow concave portion 4 are directed downward and pass through the transparent plate 6 to the thermal paper roll that is superimposed on the document (A). will be irradiated.

る。(Example) The figure shows an example of the present invention. Base 3
A pedestal 1 on which a document is placed is formed in the center of the upper surface, a vertical hole 9 is formed next to the pedestal 1, and a flush valve 2 is fixed to the horizontal wall of the vertical hole 9 at an appropriate depth. There is. The light beam irradiated from the flash bulb 2 is directed upward through this vertical hole 9.
It is impossible to directly irradiate the pedestal 1 because the side wall of the pedestal 1 is in the shadow. A pressing table 7 is placed on the upper surface of the base 3, and one end of the pressing table 7 is pivotally connected to the base 3 so that it can freely swing upward. A hollow concave portion 4 is formed in the press base 7 at a location above the vertical hole 9 of the base and the base 1 when the press base 7 is closed to the base 3, and a reflecting mirror 5 is provided on the curved inner surface of the hollow concave portion 4.
is installed. Further, at a position below the hollow concave portion 4 of the press base 7 and directly opposite the base 1 on the base 3, there is a transparent plate 16 for appropriately pressing the document A and the heat-sensitive base paper L placed on the base. Supported.
