Description

Background of the Invention

1. Field of the Invention

The present invention relates to a film transfer device, and in particular to a film transfer device including a slidable protection cap mounted thereon.

2. Description of the Related Art

U.S Pat. No. D,475,747 entitled "FILM-TRANSFERRING DEVICE FOR OFFICE USE" shows a casing of the film transferring device includes a cap hinged on a bottom side thereof to selectively fix with an application head which transfers film. Therefore, the cap is fixed with the application head to close the application head, and the cap is retained on the bottom of the casing as the application head transfers film.
The design of the above patent suffers from a problem that the cap wears the application head after the repeated engagement and disengagement therebetween. Consequently, the cap is not able to be securely fixed with the application head and the cap can not protect the application head. Another problem is that the cap has a section subject to fracture due to repeated bending. As a result, the cap can not protect the application head, and the fracture has an adverse effect on appearance.
The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art by providing a film transfer device with a slidable protection cap which is durable and convenient for use.

Summary of the Invention

According to the present invention, a film transfer device with a slidable protection cap includes a case including a compartment and a receiving section connected with the compartment, and an opening section in proximity to the receiving section. A reel mechanism is disposed in the compartment. An application head assembly is retained in the receiving section and includes an application head exposed outside the opening sections. A protection cap is slidably mounted in the receiving section between a first position and a second position. The application head concealed by the protection cap as the protection cap is in the first position. The application head exposed from the protection cap as the protection cap is in the second position.
It is an object of the present invention that the protection cap is disposed in the case and is moveable between two positions to selectively conceal or expose the application head. Thus, the application head is protected from dust and dirt by the protection cap.
It is another object of the present invention that the protection cap exposes the application head as the protection cap is in the second position. Additionally, the protection cap has position-limiting grooves which engage with protruding sections of the application head assembly to prevent the protection cap from shaking movement, which adversely influences film-dispensing operation.
It is a further object of the present invention that the application head assembly includes a fixing frame retained in the case and is prevented from displacement. Thus, the steadiness of the fixing frame is ensured and the fixing frame is prevented from loosening and displacement in the case.
