Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a portable simple slide projector.

[0002]

[Prior art]

 Conventionally, this type of slide projector uses a transparent original film such as a transparent positive film for the slide, uses a halogen bulb or a Leknon discharge lamp as the light source, and emits a strong light beam from the light source arranged at the rear of the slide to the slide. It is known to irradiate the light, magnify it with a projection lens placed in front of a slide, and project it on a screen.

[0003]

[Problems to be solved by the invention]

 The slide projector with the above configuration is large, heavy, and difficult to carry. In addition, since a commercial power supply is required, the place where it is used is limited. In addition, the slide is limited to the light-transmitting master, and a light-impermeable master such as photographic paper cannot be used.

The present invention is a portable slide projector that is small and lightweight, can be easily carried, can be used in places without a commercial power supply, and can project an optically opaque original such as photographic paper. The main purpose is to provide

[0005]

[Means for Solving the Problems]

 The portable simple slide projector according to the present invention has a housing formed into a required shape and an opening formed on the left and right side surfaces of the housing. The slide support frame inserted through one opening can be pulled out from the other opening. Irradiating light to a frame guide passage formed in the housing, a projection lens support cylinder slidably provided at a front portion of the housing, and a slide on a frame placed in the frame guide passage in the housing. A light bulb, a reflector plate in the housing for projecting reflected light from the slide toward the projection lens, and a battery housing for the light bulb formed in a part of the housing. I have.

[0006]

[Embodiment of the invention]

 As a preferred embodiment of the present invention, as shown in FIGS. 1 to 3, openings (2) are provided on both left and right sides of a housing (1) molded from a synthetic resin material, and one opening (2) is provided in the housing. A frame guide passage (3) for passing the slide support frame (A) through the other opening (2) is formed at the front of the housing (1), and two convex lenses (4a), (4a) are formed at the front of the housing (1). The supporting cylinder (5) of the projection lens (4) with the back-to-back is slidably assembled, and the battery (10) is placed on the slide photograph (6) affixed on the frame (A) in the housing. ) Is placed as a power source, a light bulb (7) is illuminated, the light of the light bulb is radiated, the reflected light is received by a mirror plate (9), and the reflected light is projected toward a projection lens (4) and placed in front of the projection lens. It is configured to project on the screen.

[0007]

【Example】

 1 to 3 show an embodiment of the present invention. In the figure, (1) is a housing formed of a synthetic resin material, and openings (2) and (2) are provided at required portions on both left and right sides, respectively. A frame guide passage (3) is formed in the housing so that the slide support frame (A) shown in (1) can be inserted and pulled out from the other opening (2).

At the front of the housing (1), a support cylinder (5) of a projection lens (4) is slidably assembled. The projection lens (4) is composed of two convex lenses (4a) and (4a), back to back. In the housing (1), a light bulb (7) for irradiating light to a slide photograph or the like (6) attached on the slide support frame (A) is provided. (8) is the reflection cover.

In the housing (1), a mirror plate (9) for projecting reflected light from the slide photograph or the like (6) toward the projection lens (4) is provided at a predetermined angle. ing. A housing (11) for a dry battery or a button battery (not shown) (10) used as a power source for the electric bulb (7) is provided at the bottom of the housing (1). (12) is a lid plate of the storage section (11). (S) is a power switch.

The slide support frame (A) is preferably made of, for example, a strip of cardboard, and the photograph (6) may be glued to a position at a predetermined interval with glue. If a pressure-sensitive adhesive layer is previously applied to the surface, it is easy to attach or replace the photograph (6).

A stopper projection (13) is provided on one side in the longitudinal direction of the slide support frame (A). The stopper convex portion (13) is used for arbitrary positioning when the slide is fed out one by one in cooperation with an engaging portion (not shown) provided on the frame guide passage side. The stopper projection may be provided on the back surface of the frame.

According to the above configuration, it is possible to enlarge and project the light-impermeable photograph or the like (6) on the screen surface. That is, the frame (A) to which the photograph for slide (6) is attached is sent out from the opening (2) of the housing (1) to the frame guide passage (3), and the photograph (6) on the positioned frame. When the light from the light bulb (7) is irradiated, an image obtained by inverting a photograph or the like (6) is displayed on the mirror plate (9) that has received the reflected light, and the image is inverted and enlarged by the front projection lens (4). Is projected on a screen (not shown) placed in front of the lens.

The portable simple slide projector having the above configuration has an advantage that it is easy to carry and can be easily used in a place without a commercial power supply.

In addition, the slide projector enlarges a photograph, a printed matter, a drawing, etc. obtained from a sticker printing machine (a photo vending machine that prints a self-portrait photograph on a stamp sheet and sells it) recently. It is suitable as an entertainment product that can be projected and enjoyed.

[0015]

[Effect of the invention]

 As described in detail above, according to the present invention, a portable and simple device that can be used in a place where there is no commercial power supply, and that can project an optically opaque original, is small and lightweight and easy to carry. A slide projector is obtained.
