Rotary image projector
First Claim
1. A rotary image projector, comprising:
- a dynamic image projector having;
a housing having;
a chamber defined therein; and
a light-projecting bore formed through a front portion of the housing to communicate with the chamber;
a lens set mounted inside the light-projecting bore of the housing and having multiple convex lenses axially arranged inside the light-projecting bore and aligned in a straight line;
a power supply mounted inside a rear portion of the housing, and electrically connected to an external power cord penetrating through the housing;
a motor being cylindrical, mounted inside the housing, electrically connected to the power supply, and having a spindle extending beyond a front face of the motor;

Abstract
A rotary image projector has a dynamic image projector. A lens set is mounted inside a front portion of a housing of the dynamic image projector, and a motor, a slide assembly and a light-casting assembly is mounted inside a rear portion of the housing. The slide assembly is mounted on a spindle of the motor and is located between the light-casting assembly and the lens set. The motor drives the slide assembly to rotate to vary a position of the slide assembly aligning to the light-casting assembly in generation of dynamic images. The projector further has a transparent inflatable figure inflated by a blower for demonstration. The dynamic image projector is mounted on the transparent inflatable figure and the inflatable figure serves as a projection screen for the dynamic image projector projects a movable dynamic image on the inflatable figure.
