Description

  The present invention is a projection image display device, and more particularly, a projection image in which two types of pictorial diagrams are set on the back side of the screen as pictorial diagrams and the two types of pictorial diagrams are combined and displayed on the screen by illumination light irradiation. The present invention relates to a display device.

  Conventionally, for example, on a wall surface or various lighting fixtures, a picture or photograph (hereinafter represented by a picture) of a natural landscape, a night sky star, or a cityscape is drawn on the front or back of a glass or plastic screen, The film body on which the picture was drawn was installed on the back side of the screen, and an illumination light source device was installed on the back side of the film so that the picture figure was displayed as a projected image on the screen surface when illuminated with illumination light. Projection image display devices are widely used.

  However, in the conventional projection image display apparatus as described above, whether it is a picture drawn on a screen or a picture drawn on a film body, the picture itself is a single type, and illumination light is used at night. When the light is irradiated, the picture is displayed brightly and clearly, but when the illumination light is not irradiated in the daytime etc., the picture is only slightly dimmed. There is no difference in itself. Therefore, there is a problem that the display contents cannot be changed or the variety cannot be obtained.

  The present invention has been made in view of the circumstances as described above, and its purpose is to display different pictures depending on whether illumination light is irradiated or not and to give variety to display contents. It is an object of the present invention to provide a projection image display device capable of performing the above.

  In order to achieve the above object, the present invention provides a projection image display apparatus in which a screen member on which a picture is projected and displayed, and two kinds of pictures as the picture are drawn on the front and back surfaces, and behind the display surface of the screen member. And an original light source sheet placed on the opposite side of the original drawing sheet with respect to the screen member, and an original light source sheet placed so that the front side is on the screen side and the back side is opposite to the screen. This is the gist. According to this configuration, when the illumination light source member is on, the picture drawn on the surface of the original drawing sheet and the picture drawn on the back surface are combined (or combined) and displayed on the screen by illumination light irradiation. On the other hand, when the illumination light source member is off, only the picture drawn on the surface of the original drawing sheet is visible from the screen, and two different pictures are displayed on the screen member by turning on and off the illumination light source member. Can be displayed.

  In the projection image display device, the screen member is made of a light transmissive material. Thereby, when the original drawing sheet is installed behind the display surface of the screen member, it is possible to visually recognize the picture drawn on the surface of the original drawing sheet through the screen without irradiating illumination light.

  In addition, the pictorial drawing drawn on the back side of the original drawing sheet is subjected to inversion processing. Thereby, when the original drawing sheet is viewed from the front side when the illumination light source member is off, it is possible to blind the picture drawn on the back surface of the original drawing sheet.

  According to the present invention, in a projection image display device, an original drawing sheet on which two types of drawings are drawn on the front and back sides is installed as a drawing on the rear side of the display surface of the screen member, and the drawing is screened by irradiation or non-irradiation of illumination light Since the picture drawn on the front side of the original drawing sheet and the picture drawn on the back side are combined and combined and displayed on the screen by irradiation of illumination light, it is displayed on the screen. Only the picture drawn on the surface can be visually recognized from the screen, and different pictures can be displayed depending on whether the illumination light is irradiated or not, and the display contents can be varied.

It is a figure which shows the display mode of the back side when the switch of the projection image display apparatus which concerns on the said embodiment figure is turned on.

  Next, embodiments and operations of the present invention will be described in detail sequentially with reference to FIGS. FIG. 1 is an external front view of a projection image display apparatus according to an embodiment of the present invention, and FIG. 2 is an external rear view of the projection image display apparatus according to the above embodiment. The projection image display apparatus according to this embodiment is an example applied to a speaker as a product. Although this speaker has a structure like a lighting fixture in appearance, it is actually a speaker as an acoustic product. In the embodiment shown in FIG. 1, the cylindrical casing 1 and the left and right end faces 2, 3 of the casing 1 are used. A speaker unit (not shown) as a sounding body arranged in the part and a control box 4 installed on the lower side of the casing for controlling the input of sound signals and the output to the speaker unit. The sound signal of broadcasting is output as sound. However, in the following description, the projection image display device will be described as described above.

  In FIG. 1, a housing 1 constitutes a screen member. The control box 4 constitutes the base of the projection image display device. The screen member 1 has a cylindrical structure and is made of a light transmissive (transparent or translucent) material such as glass or plastic material (acrylic or the like). An original drawing sheet 5 serving as a pictorial medium projected on the screen member 1 is installed inside the screen member 1, that is, behind the display surface of the screen member 1. The original drawing sheet 5 is made of paper, a resin film, or other suitable material. In a normal state (the light source is off), a material is used so that the pattern drawn on the back side cannot be seen through from the front side. Such processing is performed. The original drawing sheet 5 has two types of drawings drawn as a sketch on the front and back surfaces. FIG. 3 is a diagram showing an example of the front surface of the original drawing sheet 5, and FIG. 4 is a diagram showing an example of the back surface of the original drawing sheet 5. In FIG. 3, the lower half of the surface of the original drawing sheet 5 is a pictorial diagram showing the state of the Japanese house, the shoji door 6 (6a, 6b) with the central part open, and the floor (tatami) (Floor) 7 and cats 8 (8a, 8b) on the floor 7 are the surface patterns. The upper half of the surface of the original drawing sheet 5, that is, the area above the upper edge frame of the shoji doors 6a and 6b is also a picture area, and in this case, nothing is drawn in the upper half of the picture area. Due to the blank design.

  In FIG. 4, the lower half of the back of the original drawing sheet 5 is drawn with a picture representing the state of a Japanese house in an era (for example, the Edo period) that dates back several years. The large store 9 of that era is drawn, the storehouse 10 is drawn on the left side of the large store 9, and the first private house 11 is drawn on the left side of the storehouse 10. A second private house 12 is drawn as a symbol on the right side of the large store 9. With respect to the drawing of the house, the first private house 11 is drawn in a dark and clear shape from the substantially central part to the right part, while the left part from the central part is drawn in a light and somewhat blurred manner. The second private house 12 on the left side of the first private house 11 is also drawn in a light and somewhat blurred manner. This is determined by the relationship with the picture on the lower half of the surface of the original sheet 5, and the shoji door 6a is drawn on the surface as described above, and the houses blocked by this shoji door 6a are lightly transparent. It depends on what you see. The same applies to the shoji door 6b side. A third private house 14 is drawn as a pattern on the right side of the large store 9, and a moon 13 is drawn at a position corresponding to the sky above the houses.

  The lower half of the back surface of the original drawing sheet 5 corresponds in position to the lower half of the front surface of the original drawing sheet 5, and the drawing of the lower half of the back drawing is reversed in order to hide the design, that is, It is drawn horizontally reversed with respect to the central axis. Further, a symbol missing portion 15 (15a, 15b) exists in the lower half of the back surface of the original drawing sheet 5. Specifically, there is a missing part 15a from the large store 9 to the third private house and a missing part 15b from the warehouse 10 to the first private house 11. This is determined by the relationship with the picture on the lower half of the surface of the original drawing sheet 5, and the cat 8 (8a, 8b) is drawn on the surface as described above, and corresponds to these cats 8a, 8b. The part to be done is blank. The missing portion 15a corresponds to the cat 8a, while the missing portion 15b corresponds to the cat 8b, and the left-right positional relationship is reversed, but this is due to the inversion process described above.

  On the back surface of the original drawing sheet 5, reference numeral 16 denotes a boundary line between the upper half and the lower half of the back surface. In the upper half of this boundary line 16, a picture representing the nighttime cityscape and the stars reflected in the night sky is drawn. As a pattern, a plurality of houses 17 are drawn on the upper edge in an upside down manner. A starry sky 18 is drawn on the lower side.

  The original drawing sheet 5 on which the above picture is drawn is wound in a cylindrical shape, and is installed inside the screen member 1 so as to be aligned with the inner periphery of the screen member 1. When the original drawing sheet 5 is wound in a cylindrical shape, the front surface is directed outward, the back surface is directed inward, and the boundary 16 between the upper half and the lower half comes to the top of the screen member 1. Installed. As a result, even if the upper half and the lower half of the drawing are drawn upside down on the back side of the original drawing sheet 5, the drawing relationship is correct for any of the drawings when installed inside the screen member 1. Become. Note that it does not matter whether the upper half of the original drawing sheet 5 comes in front of the screen member 1 or whether the lower half of the drawing comes in front of the screen member 1. In this embodiment, the original drawing sheet 5 is installed such that the lower half of the drawing is on the front of the screen member 1 and the upper half of the drawing is on the back of the screen member 1 (see FIGS. 1 and 2).

  When the original drawing sheet 5 is installed on the screen member 1 as described above, the original drawing sheet 5 is arranged behind the display surface of the screen member 1 so that the front side is on the screen side and the back side is on the opposite side of the screen. Will be installed.

  In the present embodiment, an illumination light source member (not shown) is installed at the substantially central portion of the cylindrical screen member 1, that is, a portion that is opposite to the original drawing sheet with respect to the display surface of the screen member 1. The As the illumination light source member, a light bulb, a fluorescent lamp, or an LED is used. In FIG. 1, reference numeral 19 is a switch for turning on / off the illumination light source member, and 20 is an adjustment knob for adjusting the light quantity of the illumination light source member.

  The operation of the projection image display apparatus having such a configuration will be described below. When the switch 19 is turned on, the illumination light source member is turned on, and illumination light is emitted from the inside of the screen member 1. Thus, the picture drawn on the front surface of the original drawing sheet 5 and the picture drawn on the back surface are combined or combined and displayed on the screen member 1. FIG. 5 shows a display mode on the front side when the switch 19 of the projection image display apparatus according to the present embodiment is turned on. As shown in this figure, the cat 8 on the shoji door 6 and the parquet floor 7, which are pictures drawn on the lower half of the surface of the original drawing sheet 5 by being irradiated with illumination light, and the original drawing sheet 5 The picture of the house drawn on the lower half of the back, 9, 10, 11, etc., and the moon 13 combine to express the night scenery. FIG. 6 shows a display mode on the back side when the switch 19 of the projection image display apparatus according to the present embodiment is turned on.
