A signal guiding member 43a shown in FIG. 3A is used for the remote control light receiving unit 4a using the light receiving element 411a having a wide range (angle) in which an optical signal can be received. When the lower limit angle at which the optical signal emitted from the remote controller Rm is directly incident on the light receiving element 411a is A ° and the upper limit angle is D °, the upper inclined portion 431a has an inclination angle C ° of (DA). ) / 2 is not smaller and close to the value. In this case, the inclination angle C ° is (DA) / 2 + 5.

このように信号誘導部材43aの上側傾斜部431aの傾斜角C°を決定することで、

By determining the inclination angle C ° of the upper inclined portion 411b in this manner, the angle at which the optical signal incident at the angle F ° is reflected by the upper inclined portion 431b and incident on the light receiving element 411b is reduced. Since the incident angle is small, even if the light receiving range of the light receiving element 411b is narrow, in other words, an optical signal can be received even if the light receiving angle is small. Therefore, the light receiving element 411b.
And the range of selection of members constituting the electronic device is expanded.
