Abstract

PURPOSE:To eliminate a background line being a cause to mis-operation by adopting the structure of a light collection surface without partial reflection and weakening the reception sensitivity of a light incoming from a specific direction so as to give directivity to the optical receiver. CONSTITUTION:The optical receiver 1 is made up of a light receiving sensor 2, a container case 3 and a signal processing circuit contained in the container case. Then a light collection face 5 forming a light collection face 4 being recessed container case as a bowl so as not to reflect light is provided and the size of the light collection face is an angle alpha(0 deg.<alpha<=360 deg.) around the light receiving sensor 2. Furthermore, a base plate mount claw 6, a deviation preventing notch 7 formed by giving a recess to part of the base late mount claw 6, a power supply terminal, a GND terminal and an output terminal 8. Thus, even when a light disturbing an infrared ray signal required for remote control is emitted from a prescribed direction at all times, the reception of the disturbing light is suppressed and malfunction of a remote commander is considerably reduced. Furthermore, when a light from a specific direction is undesired to be received by the convenience of the user, the light is hardly received.

The figure is a cross-sectional view thereof, and the same portions as those in FIG. In this embodiment, the non-light-condensing surface part 13 is configured to be rotatable and removable, which is a difference from the embodiment of FIG. Non-light-collecting surface parts are the rotary knob 1
4 is provided, it can rotate around the light receiving sensor, and can be set at any place. It can also be attached and detached. The structure is such that a stopper hole 16 is formed in a ring portion of a non-light-collecting surface part having a shape like a fan on a ring, and a stopper claw 1 which is a part of a storage case 3 '.
With 5, it can be fixed. The size of the stopper hole is slightly larger than that of the stopper claw, and the number of holes is the number that can be fixed during one round of the non-light-collecting surface. 17
Is a base for mounting a light receiving sensor and a signal processing circuit. According to such a configuration, it is possible to respond according to the environment of the place where the remote-control-compatible electric device is placed. For example, if there is no light source that causes a malfunction, the non-light-condensing surface part can be removed to widen the maximum remote controllable range. Even if there is a light source that causes a malfunction, the non-light-collecting surface part may be rotated and set according to the direction. Further, it is not necessary to separately prepare an optical receiver having a non-light-collecting surface and an optical receiver not having it.
