<Configuration of detection / notification unit>
Next, the configuration of the detection / notification unit 4 characterizing the present invention will be described in detail.

  FIG. 2 is a perspective view showing the configuration of the arm portion of FIG. FIG. 3 is a partially enlarged view of part A in FIG. FIG. 4 is a plan view showing the configuration of the arm portion of FIG. FIG. 5 is a cross-sectional view taken along line VV in FIG. FIG. 6 is a perspective view showing the detection / notification unit with the cover removed. FIG. 7 is a partially enlarged view of the detection / notification unit in FIG.

  As shown in FIGS. 2 and 3, the detection / notification unit 4 is formed so as to form an arm shape as a whole together with the arm 1b of the main body 1 (hereinafter simply referred to as the arm 1b). The detection / notification unit 4 is configured so that the inside cannot be seen through the cover 21.

  As shown in FIGS. 4 to 7, the detection / notification unit 4 includes a notification lamp 23, a light shielding unit 24, a reflective infrared sensor 27 (particularly see FIG. 7) as a human body sensor, and a cover 21. ing. The outer shell of the arm 1b is composed of an arm-shaped housing 22. An opening (window) 28 is formed at the tip of the arm-shaped casing 22. A cover 21 is detachably fitted in the opening 28. The cover 21 is formed in a shape that forms a part of the housing 22 while being fitted in the opening 28. The cover 21 is made of a material that transmits infrared light and has a visible light transmittance such that a portion covered with the cover 21 is not visible. A support portion 22 a that supports the notification lamp 23 and the reflective infrared sensor 27 is provided at a portion facing the opening 28 of the housing 21. An information lamp 23 and a reflective infrared sensor 27 are provided on the support portion 22a. The reflective infrared sensor 27 is provided such that the light emitting unit and the light receiving unit are directed toward the opening 28. As a result, infrared rays emitted from the light emitting portion of the reflective infrared sensor 27 are transmitted through the cover 21 and radiated to the outside, and infrared rays reflected by the human body in the vicinity of the toilet seat device 101A are transmitted through the cover 21 and reflected. Light is received by the light receiving portion of the infrared sensor. The notification lamp 23 and the reflective infrared sensor 27 are provided so as to be arranged in the horizontal direction, for example, but can be provided in any arrangement.

A light passage hole 25 is formed in the light shielding portion 24. The light passage hole 25 is formed so that the optical axis 26 passes. As a result, visible light emitted from the notification lamp 23 passes through the light passage hole 25 of the light shield 24 and is formed into a beam shape. When the beam-shaped visible light passes through the cover 21, a portion of the cover 21 through which the visible light passes becomes a spot-shaped lighted region 31. The visible light emitted from the spot-shaped region 31 includes both visible light transmitted through the cover 21 and visible light scattered by the cover 21. As a result, since the spot-shaped glowing region 31 is present in isolation in the opaque cover 21 (the interior is not visible), the glowing region 31 appears clearly in the surrounding area of a single color, and the glowing region 31 is clearly visible (see FIG. 3). Therefore, the visibility of the part which notifies that the toilet seat 2 has been heated is improved. In addition, the shape of the area | region 31 which shines is not specifically limited, It can be set as arbitrary shapes.
