Description

[Detailed description of the invention] Industrial application field This invention relates to a projection toy that can be played with by projecting an original drawing with a transparent line drawing onto various objects using a movable and operable light source. It is.

Conventional Technology Various projection toys have been known for a long time, and these projection toys condense light from a light source with a lens, and use the condensed light to project an original image onto a screen or other object. It had a projection structure.

When reducing or enlarging an image, the lens is moved.

Problems that the invention aims to solve: However, if the above structure is adopted, a lens or other optical system is required, and if you want to perform further enlargement or reduction, the optical system must be moved, making the structure complicated. This increases production costs.

Furthermore, when a plurality of original images are displayed on one original image board, it is extremely difficult to selectively project the original images in the corners onto the center of the projection plate without moving the original image board.

Means for Solving the Problems In order to solve the above-mentioned problems, in the present invention, an operating arm is housed in a case so that it can be moved freely along the axial direction, and can also be freely rotated vertically and horizontally at one end. A light source is attached to the inner end of the operation arm, while a transparent original image mounting plate on which the original image board is placed is provided above the operation arm, and a transparent original image mounting plate is provided above the original image plate at a certain interval and attached to the case. A projection plate that can be opened and closed is installed on the screen.

Operation By adopting the structure described above, the light source can be manually moved freely relative to the original image via the operating arm, and the original image on the original image board can be projected selectively and with enlargement. This makes it possible to obtain a low-cost projection toy with a simple structure and a small number of parts.

Embodiments Hereinafter, details of the present invention will be explained based on embodiments shown in the drawings.

FIGS. 1 and 2 show an embodiment of the present invention. As shown in FIG. An operating arm 3 that is movably inserted and has a light source 2 at its tip and can be rotated vertically and horizontally, and a transparent original image mounting plate 5 that is placed above the operating arm 3 and on which an original image board 4 is placed. , and a projection plate (also serving as a cover) 6 attached to the case body 1 so as to be openable and closable.

By rotating or sliding the operating arm 3 (it cannot be twisted), the light source 2 can be freely moved below the original drawing board 4, thereby transferring the original picture on the original drawing board 4 to the projection screen. 6 can be projected.

The details of each part will be explained below.

The case body 1 has an opening 7 formed on one side into which the operating arm 3 is inserted, and is formed as a box with an open top end, and a battery box 9 in which a battery 8 is housed is formed in a part of the case body 1. ing.

On the other hand, the operating arm 3 has a groove 1 formed in the abutting surfaces of the bearings 10 and 11, which are divided into two upper and lower parts.
It is formed as a square rod that is slidably fitted with relatively loose frictional contact into the space having a quadrilateral cross section defined by 0a and 11a, and has a grip at its outer end. 3a is provided.

A shaft 10b protrudes from one side surface on a straight line perpendicular to the axial direction of the groove 10a of one bearing 10, and a protrusion 10c is formed on the top surface.

Further, the other bearing 11 has a shaft 11b projecting from the side opposite to the shaft 10b.

The shafts 10b and 11b are fitted into recesses 11c formed in the mating surfaces of the bearings 10 and 11 (the recess on the bearing 10 side is omitted).

Above the upper bearing 10, a support plate 12 is attached to a support shaft 1 which is protruded toward the case body 1 through a screw 13.
It is fixed at 4,14.

A cylinder 12a is protruded from the lower surface of the support plate 12, and the upper surface of the bearing 10 is in contact with the projection 10c fitted into the cylinder 12a.

Further, the lower surface of the lower bearing 11 is supported by a cylindrical body 23.

A horizontal partition plate 23a is formed in the middle of the cylindrical body 23, and this partition plate 23a and the case body 1
A spring 16 is elastically loaded between the lower surface of the partition plate 23a and the cylindrical body 15 protruding between the pillars 14, 14 on the side.

In addition, a pair of left and right support plates 1 are provided with the cylinder 15 in between.
7 and 17 are provided protrudingly, but these support plates 1
The shafts 10b, 11b are in contact with the upper end surfaces of the shafts 7,17.

In this way, the operating arm 3 is supported by the two-part bearings 10 and 11 that are integrated and constitute a spherical bearing, but the shafts 10b and 11b are supported by the support plates 17 and 17. Therefore, the operating arm 3 cannot be rotated in the twisting direction, but it is possible to slide in the axial direction and rotate in the vertical and horizontal directions, and can be kept stationary at any position.

Note that the light source 2 and the battery box 9 are connected by a lead wire 18, and the battery box 9
A battery 8 is housed inside.

On the other hand, the original picture mounting plate 5 is transparent and supported by a step 19 formed near the upper part of the inner peripheral surface of the case body 1, and is located above the operating arm 3.

Further, the projection plate 6 has a shaft 2 on one end side of the case body 1.
It is attached via 0 so that it can be opened and closed freely.

The central portion of this projection plate 6 is made transparent by installing a transparent plate 21, and an image is projected onto this projection plate 6.

It is also possible to place a tracing paper 22 on the projection plate 6 and trace the projected image.

The original drawing board 4 has an original drawing drawn with transparent lines on a black background, and the light from the light source 2 passes through this transparent line drawing area and is projected onto the transparent board 21 as an image of the lines of light.

Next, a method of using the projection toy of the present invention constructed as described above will be explained.

The user opens the projection board 6, places the desired original picture board 4 on the original picture mounting board 5, and closes the projection board 6.

In this state, a switch 4 (not shown) is operated to turn on the light source 2.

Then, the light source 2 is moved by moving the operating arm 3 in the axial direction or rotating vertically or horizontally, and is stopped at an appropriate position to project the image on the original drawing plate 4 onto the transparent plate 21.

If multiple images are drawn on the original drawing board 4, move the operating arm 3 and guide the light source 2 below the image you want to project, then arbitrarily select the corner image and move it to the center of the projection board 6. Can be projected. If the light source 2 is moved horizontally, the image projected on the projection plate 6 will also move.

Furthermore, when the light source 2 is brought closer to the original image, the image on the projection plate 6 is enlarged.

On the other hand, if nothing is placed on the projection plate 6 and the projection plate 6 is directed toward a wall or the like, it is possible to project onto the wall or the like.

Effects As explained above, according to the present invention, by moving the operating arm, a structure is adopted in which the light source can be moved below the original image and the image can be projected onto the projection plate. Images can be projected with a simple configuration without the need for a complicated mechanism, the image can be enlarged, the original image at the corner of the original drawing board can be projected onto the center of the projection board, and it can also be projected onto a wall. An excellent effect can be obtained in that projection can be performed freely.
