Embodiment Construction

[0034] Figure 5a Shown is an oblique view of the preamplifier attached to the filter.

[0035] Figure 5b yes means Figure 5a The planar view of the filter.

[0036] Image 6 It is a graph showing the result of filter characteristic implementation.

[0037] Remote control accepting device of the present invention such as Figure 5a , the noise filtering device 40 is attached to the front of the preamplifier 20, within the range of the infrared input field.

[0038] At this time, if Figure 5b , what constitutes the noise filtering device is the color image cloth attached to both sides of the preamplifier, usually black cloth, which is attached to the corresponding areas A and A' on both sides of the amplifier, that is, coated with adhesive Or use double-sided tape to attach to both sides of the preamplifier.

[0039] At this time, in order to prevent the light emitted by the 3-wavelength illuminating lamp from entering the preamplifier, the principle of using color i...

Abstract

The invention is a kind of remote receiving device; it receives the infrared signals transmitted by the transmitter and carries on the signal processing. It includes: a preamplifer which receives the infrared signal and amplifies the signal; the noise filtering device which can holdback the light with different colour temperature to infrared signal. The filtering device is made up by pasting a colour cloth on one side of the amplifier.

Description

(1) Technical field [0001] The invention relates to a remote control receiving device for eliminating noise signals generated by illuminating light. (2) Background technology [0002] The remote control transceiver device currently used is generally designed for the convenience of the user. It uses a remote infrared emission and reception device, which includes: inputting a predetermined operation command at a remote location, and sending an appropriate operation command in the form of infrared rays. Sending device (remote control transmitter); by receiving the infrared rays sent from the above remote control transmitter, and converting it into an electrical signal, and inputting it to the remote control receiving device of the electrical equipment itself through the microprocessor. [0003] For the composition of the remote control receiving device and the preamplifier, refer to figure 1 [0004] Such as figure 1 The shown remote control device 10 is an oscillator 11 tha...
