By the way, the cordless controller 52 is originally the air conditioner 5.
It is intended to enable controlled devices such as the first class to be operated from a remote location, and its primary purpose is to be placed at the operator's hand.

However, when the air conditioner 51 is used for business purposes in an office, factory, etc., it is necessary to determine the installation position of the cordless controller 52 to facilitate use by an unspecified number of people.

Therefore, conventionally, the cordless controller 52 is removably placed below the air conditioner 51 on the wall 50 to specify the setting position and to adjust the setting position on the wall 50 as needed.

<Problems to be Solved by the Invention> However, in the above conventional structure, the light receiving section 51a is connected to the air conditioner 5.
Since the cordless controller 52 is provided only on the front side of the wall 50, there is a problem in that when transmitting light is emitted while the cordless controller 52 is placed on the wall surface 50, it does not reach the light receiving section 51a. Therefore, it is necessary to take out the cordless controller 52 from the wall 50 and return it to the wall 50 after controlling the air conditioner 51, which makes controlling the air conditioner 51 extremely troublesome.

In order to solve such problems, Japanese Patent Application Laid-Open No. 1-1507
Publication No. 35 discloses a structure in which a light receiving section 51b is also provided on the lower surface of the air conditioner 51 so that transmitted light transmitted to the lower surface of the air conditioner 51 can also be received. is disclosed.

However, in order to provide the two light receiving sections 51b in the air conditioner 51, it is necessary to significantly change the design of the air conditioner 51.
Not only is it difficult to implement, but it also increases the cost of the product.

The present invention has been made in view of the above-mentioned problems, and allows the operator operating the cordless controller to reflect the transmitted light and indirectly transmit the transmitted light to the light receiving section, thereby allowing the same design change to be made to the controlled device. It is an object of the present invention to provide a transmission light transmitting device and a transmission light transmitting method of an improved remote control mechanism that can be easily implemented at low cost without adding any additional equipment.

Means for Solving the Problems> In order to solve the above problems, a transmission optical transmitter of a remote control mechanism according to the present invention includes a controlled device fixed to a wall surface and a light receiving section provided in front of the controlled device. and,
a cordless controller that remotely controls the controlled device by transmitting transmitted light to a light receiving section, and the cordless controller is removably disposed on the wall below the controlled device; The transmitting device is characterized in that an indirect transmission mechanism is provided that indirectly transmits the transmitted light to the light receiving section by reflecting the transmitted light to an operator operating the cordless controller.

Further, in the transmission light transmission method of the remote control mechanism according to the present invention, the transmission light is transmitted from a cordless controller detachably disposed below the controlled device on the wall surface to the light receiving section in front of the controlled device fixed to the wall surface. The transmission light transmission method for a remote control mechanism that transmits light and performs remote control is characterized in that the transmission light is reflected to an operator operating the cordless controller to indirectly transmit the transmission light to the light receiving section.

<Operation> The transmitted light transmitted from the cordless controller is reflected to the operator and is indirectly transmitted to the light receiving section provided in the front of the controlled device.

<Example> Hereinafter, embodiments will be described in detail with reference to the accompanying drawings showing examples.
