In this embodiment, the display device 10 is attached to the image forming apparatus 900, but the display device 10 can be attached to a device other than the image forming device such as various communication devices and various electric appliances. .

  The display device 10 includes a display device main body 20, and the display device main body 20 is attached to the image forming apparatus main body 910 using an attachment member 22.

  In FIG. 2, the display device 10 is shown from the front side. As shown in FIG. 2, a touch panel 40, a light emitting unit 42, a light emitting unit 44, an operation unit 46, and an operation unit 48 are attached to the front surface of the display device main body 20. The touch panel 40 has a function for displaying the state of the image forming apparatus 900 and a function for operating the image forming apparatus 900. In order to operate the image forming apparatus 900 using the touch panel 40, an operator touches a point or area such as a picture or pictogram displayed on the touch panel 40 with a hand, a pen called a dedicated stylus (not shown), or the like. Information on the touched screen position is sensed by applying pressure with a general pen or the like, and output to the image forming apparatus 900 as a signal.

  The light emitting unit 42 and the light emitting unit 44 emit light with a predetermined color, for example, to indicate the state of the image forming apparatus 900. The operation unit 46 and the operation unit 48 are used to operate the image forming apparatus 900, and for example, a push-type switch device can be used.

A light emitting unit 60 is further attached to the front surface of the display device body 20. The light emitting unit 60 emits light of a plurality of different colors, for example, and emits red light and blue light, for example.

  FIG. 3 shows a cross section of the display device 10. The display device 10 has the display device body 20 as described above, and the light transmission member 26 that can transmit light is attached to the display device body 20. An outer portion of the light transmissive member 26 in the display device main body 20 is used as the light emitting unit 60 (see also FIG. 2). As the light transmissive member 26, for example, plate-like glass, plate-like resin, or the like can be used.

  Further, in the display device main body 20, for example, a first light emitting element 62 and a second light emitting element 64 that emit light of different colors and a prism 100 used as a light guide member are arranged. For example, an LED (light emitting diode) that emits blue light can be used as the first light emitting element 62, and an LED that emits red light can be used as the second light emitting element 64, for example. In addition, the first light emitting element 62 and the second light emitting element 64 emit the same amount of light.

  The second light emitting element 64 is disposed at a position farther from the irradiation surface 120 described later than the first light emitting element 62.

  The prism 100 has a first incident surface 102, a second incident surface 104, a reflecting surface 110, and an irradiation surface 120. The first incident surface 102 is a surface on which light emitted from the first light emitting element 62 is incident, and the second incident surface 102 is a surface on which light emitted from the second light emitting element 64 is incident. is there. Further, the reflecting surface 110 has light emitted from the first light emitting element 62 incident from the first incident surface 102 and light emitted from the second light emitting element 64 incident from the second incident surface 104.

For this reason, a space S that is not formed when the length L1 and the length L2 are the same can be formed inside the display device main body 20.

  Further, the angle θ2 on the prism 100 inner side formed by the second incident surface 104 and the irradiation surface 120 is smaller than the angle θ1 formed on the prism 100 inner side formed by the first incident surface 102 and the irradiation surface 120. The direction of one incident surface 102 and the direction of the second incident surface 104 are determined. The angle θ2 can be set to 82 °, for example, and the angle θ1 can be set to 90 °, for example.

  In the display device 10 configured as described above, the angle at which the light emitted from the second light emitting element 64 is refracted toward the irradiation surface 120 when passing through the second incident surface 104 is the first light emission. This is larger than the angle at which the light emitted from the element 62 is refracted toward the irradiation surface 120 when passing through the first incident surface 102. Therefore, although the second light emitting element 64 is disposed at a position farther from the irradiation surface 120 than the first light emitting element 62, the light emitted from the first light emitting element 62 and irradiated from the irradiation surface 120 The difference between the amount of light and the amount of light emitted from the second light emitting element 62 and irradiated from the irradiation surface 120 can be suppressed.

The third light emitting element 64 emits light having a color different from the color of light emitted from the first light emitting element and the color of light emitted from the first light emitting element, for example, emits green light. As the third light emitting element 64, for example, an LED emitting green light can be used.

  In the second embodiment, the amount of light emitted from each of the first light emitting element 62, the second light emitting element 64, and the third light emitting element 66 is equal. The second light emitting element 64 is arranged at a position farther from the irradiation surface 120 described later than the first light emitting element 62, and the third light emitting element 66 is described later than the second light emitting element 64. It is arrange | positioned in the position away from the irradiation surface 120 to perform.

The first light emitting element 62, the second light emitting element 64, and the third light emitting element 66 are disposed on one end side of the prism 100 with respect to the prism 100.

  In the second embodiment, the angle θ2 on the prism 100 inner side formed by the second incident surface 104 and the irradiation surface 120 is the angle θ1 on the prism 100 inner side formed by the first incident surface 102 and the irradiation surface 120. The direction of the first incident surface 102 and the direction of the second incident surface 104 so that the angle θ3 on the inner side of the prism 100 between the third incident surface 106 and the irradiation surface 120 becomes smaller than the angle θ2. And the direction of the 3rd entrance plane 106 is defined.

  In the display device 10 according to the second embodiment configured as described above, the light emitted from the second light emitting element 64 is refracted toward the irradiation surface 120 when passing through the second incident surface 104. The angle is larger than the angle at which the light emitted from the first light emitting element 62 is refracted toward the irradiation surface 120 when passing through the first incident surface 102, and the light emitted from the third light emitting element 66 is The angle refracted toward the irradiation surface 120 when passing through the third incident surface 106 is refracted toward the irradiation surface 120 when the light emitted from the second light emitting element 64 passes through the second incident surface 104. It is larger than the angle to do.

  For this reason, the second light emitting element 64 is arranged at a position farther from the irradiation surface 120 than the first light emitting element 62, and the third light emitting element 66 is closer to the irradiation surface 120 than the second light emitting element 64. Although arranged at a distant position, the amount of light emitted from the first light emitting element 62 and irradiated from the irradiation surface 120 and the amount of light emitted from the second light emitting element 62 and irradiated from the irradiation surface 120 And the amount of light emitted from the third light emitting element 66 and irradiated from the irradiation surface 120 can be suppressed.
