Description

[Detailed description of the invention] <Industrial application field> This invention is a remote control that transmits a remote control signal as an optical signal to a remote control signal receiving section of a television receiver, video tape recorder, air conditioner, audio equipment, etc. It is related to the transmitter.

<Summary of the invention> The present invention relates to a remote control transmitter that can change the rectilinear angle of the optical signal to a desired angle when transmitting the remote control signal as an optical signal to a receiving section.

<Prior art> As shown in FIG. 3, a conventional remote control transmitter of this type has internal parts 2 such as an IC, a light emitting element 3, and a remote control operation button 4 arranged on a printed circuit board 1. 1 is disposed in a remote control case 5, and a panel 6 is attached to the remote control case 5, and when the remote control operation button 4 is operated, the light emitting element 3 passes through the panel 6 and the television receiver is set. , a predetermined remote control signal is transmitted as an optical signal to a remote control signal receiving section of a video tape recorder or the like.

<Problem to be solved by the invention> If the remote control transmitter is configured as described above, the angle at which the remote control signal is transmitted as an optical signal (the straight angle of the optical signal)
is fixed to the remote control case, and for this reason, when transmitting the remote control signal as an optical signal to the receiving section of equipment such as a television receiver, video tape recorder, etc., the location where the equipment is installed, for example, If it is above, it is necessary to hold the remote control case and set the transmitting angle to match the receiver of the device, which has the disadvantage of making the transmitting operation cumbersome.

This invention eliminates the above drawbacks,
The purpose is to provide a remote control transmitter that does not require a remote control case to adjust the transmitting angle to suit the receiving section of the device and can easily perform transmitting operations.

<Means for Solving the Problems> The present invention provides a remote control transmitter that transmits a remote control signal as an optical signal to a remote control signal receiving section of a television receiver, video tape recorder, etc. This configuration includes a reflecting mirror that changes the angle to a desired angle.

<Operation> By changing the angle of the reflecting mirror, the straight angle of the optical signal is changed to a desired angle, and the signal is transmitted to a remote control signal receiving section of a television receiver, video tape recorder, etc.

<Embodiment> An embodiment of the remote control transmitter of the present invention will be described below with reference to FIGS. 1 and 2.

The remote control transmitter of the present invention has an IC mounted on a printed circuit board 11 as shown in FIGS. 1 and 2.
etc., internal parts 12, light emitting element LED 13 and remote control operation button 14 are arranged, and the printed circuit board 11 is installed in the remote control case 1.
5, and the remote control case 1
5 includes a reflecting mirror 16 for changing the straight angle of the light (infrared) signal from the light emitting element 13 to a desired angle.
A slide knob 17 for changing the angle of the reflecting mirror 16 is disposed on the remote control case 15, and a panel 18 is attached to the remote control case 15. By operating the panel 18 from the light emitting element 13 through the reflecting mirror 16.
The optical signal transmits a predetermined remote control signal as an optical signal to a remote control signal receiving section of a television receiver, video tape recorder, etc.

In the above configuration, the optical signal from the light emitting element 13 is reflected by the reflecting mirror 16 and travels straight in the direction A. However, at this point, the slide knob 17 must be slid from the position D to the position F in FIG. Accordingly, the angle of the reflecting mirror 16 changes from the position G to the position H using the reflecting mirror mounting portion 19 as a fulcrum, and the light from the light emitting element 13 travels straight in the direction B. In this way, by sliding the slide knob 17 and changing the angle of the reflecting mirror 16, the straight angle of the optical signal can be changed to a desired angle.

<Effects of the invention> Since the remote control transmitter of the invention has the above configuration, the straight angle of the optical signal can be changed to a desired angle with a simple operation, eliminating the troublesome transmission operation. Moreover, since a reflector is placed inside the remote control case and the angle of the reflector is manually changed to a desired angle using a knob, the desired angle change can be changed in an analog manner. The angle of the reflector can be easily and reliably set to the desired angle using the knob. Therefore, the transmitter body can be set at any position on a desk or on a nearby object without fail. In addition, the reflector can be reliably fixed at the desired angle without any unintended external forces being applied to the reflector, ensuring reliable transmission in the desired direction. This has the effect that it can be operated even when placed on a desk or on a familiar object.
