Abstract:
A projection device for projecting images on a surface of the device includes an outer housing having a front translucent screen, a projection module frame mounted on an inner surface of the outer housing, and a projection roller frame supported by the projection module frame. The projection roller frame includes first and second spaced apart rollers rotatable respectively on two opposite cylindrical ends integrally formed on a lampshade. A cylindrical projection film is held between the first and second rollers. A light source is mounted inside the lampshade so that an image formed on the projection film can be projected on the front translucent screen by the light source. The device further includes a gear mechanism for driving the rollers, a position-limiting mechanism, and a speaker.

Claim (Index 3):
The projection device as claimed in  claim 2 , further comprising:\n (a) a cylindrical member formed at a center of a surface of the at least one of the first and second rollers facing the projection module frame; (b) a plurality of switch actuators formed around an outer circumference of the cylindrical member; (c) a switch provided on a switch box formed on a surface of the projection module frame facing the at least one of the first and second rollers, the switch being connected with an integrated circuit, and actuatable by the switch actuators; (d) a pin having an enlarged head, the pin being slidably received in a sleeve formed on the surface of the projection module frame; (e) a spring mounted around the pin for biasing the enlarged head of the pin against the surface of the at least one of the first and second rollers; and (f) a plurality of recesses formed on the surface of the at least one of the first and second rollers around the cylindrical member, the recesses being engageable with the enlarged head of the pin; (g) wherein when the motor is started, the at least one of the first and second rollers rotates via the gear mechanism until the switch is actuated by one of the switch actuators, and when the switch is actuated, the motor is switched off, and wherein the enlarged head of the pin is caught and held by one of the recesses, thereby holding the projection film in a position where the image is projectable on the translucent screen.
