The projected light flux of the picture of b is again reflected toward the half mirror h and transmitted therethrough,
A reflecting mirror i that is directed toward the projection lens a and a light shield f that rotates around this reflecting mirror i are provided. By rotating the light shield f, various light beams reflected from the reflecting mirror i are shielded, so that the image is projected. Phase change is applied to the image,

致している必要がある。However, in the conventional phase projector shown in FIGS. 2 to 4, in the phase change device c installed between the projection lens a and the original plate b, the axis e orthogonal to the optical axis is used. Although the light shield f attached to the light shields the light flux in various ways, the shape at the time of the lacking of the image is dependent on whether the light shield f and the light flux g from the projection lens a to the original plate b have the same size. Affect. For example, (d) and (e) of FIG.
If the light shield f is larger than the light beam g as shown in (3), the sharp tip shape of the crescent moon cannot be reproduced. In order for the shape at the time of chipping to be proper, the sizes of the light shield f and the light flux g must match.
【0009】光束gは原板bの側に収束光となっている
ので、遮光子fを光軸方向に移動させると、遮光子fと
光束gの大きさが一致する状態が簡易に得られる筈であ
る。Since the light beam g is convergent light on the side of the original plate b, if the light shield f is moved in the optical axis direction, a state in which the light shield f and the light beam g have the same size should be easily obtained. Is.

正な条件を満足するのに時間が掛かるし面倒である。However, in practice, the light shield f is installed at the center of the rotation mechanism of the phase change device c, and it is difficult to move it in the direction along the optical axis. While viewing the projected image, the light shield f itself is additionally processed so as to match the size of the light flux g, or the light shield f of several sizes is prepared, and a trial projection using these is performed. Are sequentially performed to search for and use the light shield f having the same size as the light flux g. Therefore, it takes time to satisfy the appropriate conditions and it is troublesome.

に再現できないと言う問題もある。On the other hand, in the reflection type projector having the structure as shown in FIGS. 3 and 4, with respect to the reflecting mirror i or the original plate b on which a picture is drawn, the reflecting mirror i and the original plate b are rotated. Since the light shield f cannot be installed unless the light shield f is larger, it is possible in principle to match the size of the light flux g with the size of the light shield f regardless of the difference in the specific form. Can not. In short, a small circle (original plate) is covered with a light shield f having a large radius, and there is a problem that a thin moon cannot be reproduced with high accuracy.

Is to simply match the size of the projection light beam with the size of the projected light flux so that a highly accurate reproduced image can be obtained.

ズを含むことを特徴とするものである。In order to achieve the above-mentioned object, the phase projector according to the invention of claim 1 is projected between an original plate and a projection lens for projecting an image of the original plate. In a phase projector that is equipped with a phase changing device that causes the image to be distracted, the projection lens moves to a part of its optical system along the optical axis, and the size of the outermost light flux from the projection lens to the original plate is increased. It is characterized by including a movable lens whose height can be changed.

ストは掛からない。In such a structure, the light shield rotatably attached to the axis orthogonal to the optical axis of the phase change device is rotated between the projection lens and the original plate to reach from the projection lens to the original plate. Converging light is blocked according to the rotation position,
The original image projected by the projection lens can be disappointed. In particular, when a part of the moving lens of the optical system of the projection lens is moved along the optical axis, the size of the outermost luminous flux of the converged light from the projection lens to the original plate changes, so that the moving lens is moved in the optical axis direction. The height of the optical path of the outermost light flux of the convergent light can be adjusted by a simple optical operation to adjust the position so as to match the radius of the light shield to be used, whereby the size of the convergent light and the light shield can be reduced in a short time. It can be matched and reproduced with high precision even on a thin moon. In addition, the structure does not become particularly complicated, and the cost is less than that in the case of spending a great deal of labor and time in the past.
