(3) Configuration of FL Tube Next, the configuration of the FL tube 5 will be described with reference to FIG. For example, the FL tube 5 has a light-emitting element 30 disposed on each side of a square that is connected in the vertical direction in the display area 5a, for example, so that letters made of alphabets such as “a to z” are formed. In addition, numbers “0 to 9” can be displayed, and a large number of light emitting elements are provided so that a plurality of characters can be displayed in the entire display area 5a. The FL tube 5 causes each light emitting element 30 to emit light so as to indicate a meaningful character, character string, number, or the like, so that a meaningful character, character string, number, or the like (hereinafter, referred to as a display region 5a). These are called display objects) 5b.

  In the FL tube, the green component of visible light emits stronger light than other color components. Therefore, the color of the display target 5b displayed in the display area 5a by the FL tube 5 emitting light (hereinafter referred to as display color) includes color components other than green in visible light. Nevertheless, it looks greenish as a whole (hereinafter simply referred to as green).

(4) Configuration of Display Panel Next, the configuration of the display panel 4 will be described with reference to FIG. The display panel 4 is made of a transparent plate formed from a plastic material such as polycarbonate, and the front of the display panel 4 when the user views the apparatus main body 2 from the front side of the main body (hereinafter referred to as the panel). Light is transmitted from the front surface 4b to the back surface (hereinafter referred to as the panel back surface) 4a or from the panel back surface 4a to the panel front surface 4b. Further, the display panel 4 is selected so that the panel front 4b of the display panel 4 is selected to be larger than the display area 5a of the FL tube 5, so The music reproducing apparatus 1 is provided so that the half is covered and the substantially center of the display panel 4 on the panel back surface 4 a side faces the display area 5 a of the FL tube 5.

  As a result, the display panel 4 uses light (hereinafter referred to as display light) emitted from the display area 5a in response to the display of the display target 5b on the display area 5a of the FL tube 5 to the display panel 4 Can be transmitted from the panel back surface 4a side to the panel front surface 4b side. That is, the display panel 4 can show the user the display target 5b displayed in the display area 5a of the FL tube 5 provided on the panel back surface 4a side through the display panel 4.

  Here, in the panel back surface 4a of the display panel 4, the region corresponding to the display region 5a by facing the display region 5a of the FL tube 5 (hereinafter referred to as a display corresponding region) 4ax includes the FL The display light emitted from the display area 5a of the FL tube 5 is applied by applying a paint that changes the color of the display light emitted from the display area 5a of the tube 5 (hereinafter referred to as display light changing paint). A light-transmitting film (hereinafter referred to as a display light changing film) MA for changing the color of the film is formed in advance.

  Such display light changing paints include a light-colored light-colored paint that transmits red and blue components (that is, light) of visible light and absorbs and attenuates green light, and each color of visible light. It absorbs light to the same extent and attenuates it (that is, reduces the brightness of the entire visible light) and mixes light transmissive paint with a gray smoke color. As a result, the panel rear surface 4a of the display panel 4 is mixed. When the display light changing film MA formed in the display corresponding region 4ax transmits the display light emitted from the FL tube 5, the display light changing film MA absorbs and attenuates the green light of the display light and reduces the entire display light. It is designed to reduce brightness. Incidentally, the light-transmissive display light changing film MA referred to here is, for example, displayed when the display target 5b displayed in the display area 5a of the FL tube 5 is viewed through the display light changing film MA. It refers to a film that allows the shape of the display target 5b to be visually recognized as it is even if the color of light is changed.
