Abstract

PURPOSE:To decrease the number of originals to be prepared by providing a masking member for coloring, light shielding, or dimming on the optical path of projection of originals, and providing a member which moves automatically the masking member to an optional position. CONSTITUTION:A masking device has the masking member 1 for projecting an arrow-shaped image upon a projection image of an original on its optical path of projection. Then, the masking member 1 is made of, for example, colored light-transmissible synthetic resin, etc., to color the projected image, and also made of an opaque material to shield only the image pickup part. The masking member 1 is fixed to a transparent belt 2 and movable to an optional position. Consequently, the masking work on a projector provided to an OHP body is facilitated and the number of originals to be prepared is reduced.

Conventionally, there are two main methods for projecting a part of an image projected on an OHP or the like by coloring or blocking light, or by reducing the amount of light of a part of the image.

(1) 彩色するための着色したマスキング部材。(1) A colored masking member for coloring.

However, in the former method (1), when masking many different parts of the same manuscript, it is necessary to prepare the required number of manuscripts in advance and attach a masking member to each manuscript. Moreover, the work of preparing a manuscript is complicated and requires a long time. Furthermore, when OHP is used, the same original document with only a different type and attachment position of the masking member must be replaced and explained each time, making the replacement work complicated. Furthermore, in the latter method (2), when using an OHP, the masking member must be superimposed on the document, and the overlapping position must be changed each time when explanations are given, which requires a complicated process.
