Description

  The present invention relates to an image forming apparatus, and more particularly, to an image forming apparatus including a plurality of light emitting element units that emit display light.

  2. Description of the Related Art Conventionally, a switch or button (for example, see Patent Documents 1 to 4) having a plurality of light emitting element portions that emit display light, or an image forming apparatus including such a switch or button is known.

  In Patent Document 1, a transparent resin (light guide member) provided circumferentially on the outer side of a key top (push button) and a plurality of transparent resins arranged on the outer side of the circumferential transparent resin as viewed in a plan view. A switch including a light source (light emitting element portion) is disclosed. In the switch according to Patent Document 1, the transparent resin has a circumferential shape so as to face the light source and the circumferential light emitting portion (light emitting surface) and the light guide portion arranged inside the plurality of light sources when viewed in a plan view. And a circumferential reflection part that reflects light emitted from the light source in the inner direction. As a result, the light emitted from the light source is reflected inward by the circumferential reflection portion, so that the circumferential light guide portion is irradiated from the outside, causing the circumferential light emitting portion to shine over the entire circumference.

  Moreover, in the said patent document 2, the light guide part (light guide member) which has the light emission part (light emission surface) provided in the outer periphery on the outer side of a button part, and planar light emission part of planar view seeing planarly. A push button provided with a plurality of light sources (light emitting element portions) arranged inside is disclosed. In the push button according to Patent Document 2, the light guiding portion is formed in a convex shape so as to protrude toward the light source side, and the light emitted from the light source is located inside the circumferential light emitting portion when viewed in plan. It is the structure which injects into a light guide part from the part which opposes the light source. Thereby, the light emitted from the light source is incident on the light guiding unit from the inside of the circumferential light emitting unit, and repeatedly reflected inside the light guiding unit, while being reflected on the circumferential light emitting unit disposed outside the light source. Led. For this reason, it is possible to make a circumferential light-emitting part shine over the entire circumference.

  Moreover, in the said patent document 3, it arrange | positions at the push button part (light guide member) which makes the disk-shaped one surface the light emission surface, and the lower side (other surface side) of a push button part, and protrudes below. Thus, there is disclosed a push button including a cone-shaped pusher portion (light guide member) formed in a convex shape and a plurality of light emitting element portions that irradiate light to a side surface of the pusher portion.

In this case, if the number of light sources is constant, there is a range in which light is not irradiated to the circumferential reflecting portion depending on the diameter of the circumferential light emitting portion and the light guiding portion, and the reflected light is also reflected in the light guiding portion. An unirradiated range may occur. For this reason, there is a problem that it is difficult to uniformly illuminate the circumferential light emitting part.

  In the push button described in Patent Document 2, the light emitted from the light source is incident on the light guiding unit from the inside of the circumferential light emitting unit, and repeatedly reflected inside the light guiding unit, while being outside the light source. Therefore, it is necessary to form the light guiding portion in a complicated shape. For this reason, since it is difficult to easily guide the light from the light source to the light emitting part, there is a problem that it is difficult to uniformly illuminate the circumferential light emitting part.

  Further, in the push button described in Patent Document 3 and the dial button described in Patent Document 4, it is premised that the disk-shaped and plate-shaped light emitting surfaces are illuminated. Therefore, the circumferential light emitting surface can be illuminated. There is a problem that it is difficult.

  As shown in FIGS. 2 and 7 to 9, the infrared filter member 21 has a dome shape and is disposed so as to cover the display LED 11, the infrared receiver 12, and the switch unit 13 a. The infrared filter member 21 has a filter function that blocks visible light and transmits infrared light, and is integrally formed so as to include a switch pressing portion 21a at a position facing the switch portion 13a.

  In the present embodiment, as shown in FIGS. 2, 7, and 10 to 14, the reflecting member 22 has a function of reflecting light emitted from the four display LEDs 11 and is substantially conical. It is formed so as to integrally include four reflecting portions 22a formed in a shape. As shown in FIGS. 2 and 7, the four reflecting portions 22 a are formed in a convex shape so as to protrude toward the display LED 11 (lower side), and each has a conical shape near the center of the four display LEDs 11. The top of the shape is arranged. As a result, as shown in FIG. 7, the light emitted from the display LED 11 can be reflected so as to spread uniformly in the outer direction of the respective reflecting portions 22a.

It is configured. In this way, the attachment portion 24a of the button support portion 24 is fixed. The ring portion 24c has an L-shaped receiving portion 24f that prevents the light guide member 23 from falling off at the lower portion of the inner peripheral surface 24b. Further, as shown in FIG. 5, the light guide member 23 to which the infrared filter member 21 is attached is inserted into the ring portion 24c in the direction of the arrow F, and the power button 20 is assembled. The arm portion 24d has one end fixed to the upper end of the mounting portion 24a and the other end fixed to the lower surface of the ring portion 24c. That is, the assembled power button 20 is supported by the arm portion 24d extending from the fixed mounting portion 24a. Specifically, as shown in FIG. 18, the power button 20 to which the mounting portion 24a of the button support portion 24 is fixed has the arm portion 24d attached to the arm portion 24d with respect to the pressing force P in the arrow F direction. It is supported so as to be movable in the pressing direction (arrow F direction) by bending with one end on the side of the portion 24a as a fulcrum. Thus, when the power button 20 is pressed in the direction of the arrow F, the arm portion 24d bends with one end portion on the attachment portion 24a side as a fulcrum, so the switch pressing portion 21a provided on the infrared filter member 21 is The switch part 13a is pressed by moving in the pressing direction. In addition, when the pressing force P is released, the arm portion 24d that has been bent and deformed is moved upward by the urging force, and the power button 20 is returned to the original position.
