Disclosed is a small projection toy, wherein the units of a small projector can be built easily and removably in a small article of various types in order to project an image film and enjoy the image, and the value is increased by making the small projection toy portable by being fixed to a key holder or the strap of a cellular phone. A small projection toy has a structure which permits a small projector consisting of a projection lens barrel and a battery unit to be stored in a small article of various types, and since an incorporated image film can be projected and watched, the value is increased. The small article consists of a lens barrel inserting portion into which the projection lens barrel is inserted and a battery storage portion in which the battery unit is stored, and since said portions can be separated and divided, the lens barrel can be attached and removed easily by dividing said portions. Since the battery storage portion can be divided into two in the battery storage room on the center line, the battery can be attached, removed, and replaced easily.

To provide: a water-discoloring drawing toy which, when a writing utensil or applicator for water adhesion is applied thereto, produces a multicolor image and which eliminates the monotonous production of monochromatic images in a related-art technique and is rich in unexpectedness and changes; and a water-discoloring drawing toy set including this drawing toy. A water-discoloring drawing toy 1 having such a constitution that a drawing made by applying a writing utensil or applicator for water adhesion produces a multicolor image, the drawing toy comprising: a substrate; many non-discoloring images differing in color tone and adjoining each other disposed on the substrate so that at least two color tones per 100 cm 2 can be visually recognized in the part having the non-discoloring images; and a porous layer for preventing the non-discoloring images from being seen in the ordinary state, the porous layer being disposed over the non-discoloring images and comprising a binder resin and a low-refractive-index pigment fixed therein in a dispersed state, the porous layer having a difference in transparency between a liquid-impregnated state and an unimpregnated state. Also provided is a water-discoloring drawing toy set which comprises the water-discoloring drawing toy 1 and a writing utensil 3 or applicator for water adhesion.

The invention concerns an optical device for producing a visual illusion by holding a mirror under one's eyes. More particularly, it concerns a device for fixing on a user's head a horizontal support comprising a mirror and located just below his eyes. It consists of a support (1) whereon is fixed a mirror (2). Two perpendicular stop elements (3a and 3b), resting on the user's cheeks enable to maintain the horizontal support (1). Two linking branches (4a and 4b) with fixing straps (5a and 5b) are attached with the fixing straps to the branches (4a and 4b) so as to press one against the other above the user's head, thereby enabling to adjust the height of the device. Two fixing straps (6a and 6b) are attached to the branches (4a and 4b) to press one against the other behind the user's head so as to maintain the whole device pressed against his face.
