Abstract
A toy projector (10) is equipped with a light source (11), a non-light-transmitting member (13) having at least one light-transmitting part (14) which transmits the light from the light source (11), a member (15) having light-transmitting designs provided in a direction other than the direction in which the light-transmitting portion (14) has been placed with respect to the light source (11) , a mirror (19) reflecting the said design, and a lens (17) arranged between the said mirror (19) and the member (15) having the said design. The light from the said at least one light-transmitting part (14) and the design reflected by the said mirror (19) are projected on to the same surface.
Claims9
A toy projector comprising:
- light source means;
- a first light-transmitting member having a first light-transmitting design through which light from the light source passes along a first path so as to form a first projection on a projection surface,
- a second light-transmitting member having a second light-transmitting design through which light from the light source passes along a second path;
- a movable mirror onto which light passing along said second path impinges, said light reflecting off said mirror so as to form a second projection on said projection surface;
- focussing means for focussing light passing along said second path;
- and
- drive means for causing reciprocating movement of said mirror along a predetermined path so that said second projection is moved relative to said first projection on said projection surface.
A toy projector comprising:
- a light source;
- a first light-transmitting member having a first light-transmitting design through which light from said light source passes along a first path so as to form a first projection on a projection surface,
- a second light-transmitting member having a plurality of light-transmitting designs, said light from said light source passing through a selected one of said designs along a second path;
- a movable mirror onto which light passing along said second path impinges, said light reflecting off said mirror so as to form a second projection on said projection surface;
- focussing means arranged between said second light-transmitting member and said mirror for focusing light passing through said second light-transmitting member onto said mirror;
- and
- drive means for causing step-wise movement of said second light transmitting member wherein a different one of said plurality of designs is moved into said second light path at each step, said drive means further being operative for causing reciprocating movement of said mirror along a predetermined path so that said second projection is moved relative to said first projection on said projection surface.
