Description

[Detailed description of the invention] The present invention aims to provide a transmitting device that can generate many types of remote control signals with a small number of keys and is easy to handle when held in the hand. be.

Many devices are used to control television receivers, etc. by remote control, but if you want to increase the number of functions that can be controlled in such devices, you need to increase the number of keys on the keyboard or use common keys. Even for keyboard input, a switch must be provided to generate different signals.

However, the former method has the disadvantage of increasing the size, and the latter method has many types of display around each key top of a single keyboard, making it difficult to understand. However, there is a drawback that the provisionability becomes worse.

Therefore, it is an object of the present invention to overcome these conventional drawbacks and provide a remote control transmitting device that is easy to understand and easy to operate without increasing its size.

Hereinafter, the present invention will be described in detail with reference to the drawings showing one embodiment thereof.

1 to 6 show its structure, and FIG. 7 shows its electrical circuit diagram.

In the figure, 1 is a housing of a remote control transmitter, and a signal generation circuit 2 for generating a remote control signal is housed inside the housing.

In this embodiment, the signal generation circuit 2 includes a remote control pulse generation circuit 3 using known integrated circuit elements (for example, an SAB 3210 manufactured by Siemens Corporation that generates a 6-bit pulse coded signal), and an infrared light emitting diode 4. and a transmitting circuit 5 that drives the transmitter and emits an infrared light signal for remote control.

6 and 7 are transistors for driving the same, and 8 is a power supply.

The light emitting diode 4 is provided on one side of the housing, here the front side.

Furthermore, the casing 1 is provided with a keyboard 9 for inputting remote control instructions on one side for operation, and 30 key switches 10 are provided thereon.

These key switches 10 are connected in a matrix between the key search pulse generation terminal and the power terminal of the remote control pulse generation circuit 3, as shown in FIG.
The remote control pulse to be generated can be switched.

On the other hand, a cover plate 13 is provided on the upper surface of the keyboard 9, and has a through hole 12 in a portion facing the key top 11 of each key switch 10.

A display plate 14 is slidably provided between the keyboard 9 and the cover plate 13.

This display board 14 is composed of a frame 15 made of a hard molded product and a light elastic display film 16 stretched over the central part of the frame 15. Displays 17 I, 17 for different instruction input displays displayed through the through hole 12 when slid and when slid forward as shown in FIG. 1 II, respectively.
II, print it out, etc., and prepare it.

Furthermore, the housing 1 has two sliding positions I for the display board 15.
, II, for switching the remote control pulse generating circuit 3 to generate different remote control pulses even in response to instruction manual power from the same key switch 10, depending on which slide position it is in. 18 is provided, and its operating knob 19 is fitted into a through hole 20 formed in the frame 15 of the display board 14 and a through hole (L21) formed in the cover plate 13, so that the display board 15 can be slid at the same time by switching the switch 18. That's what I do.

By switching this switch 18, the switching circuit 22 is turned on and off, and by switching whether or not to apply the eighth key search pulse from the remote control pulse generation circuit 3, the same key switch 10 is operated. The circuit is constructed in such a way that different remote control pulses are generated at slide positions I and II even if the remote control pulses are moved.

With this configuration, when in use, the operation knob 19
By switching the switch 18, the types of remote control pulses generated can be changed into two types, and 60 types of remote control can be performed using the 30 key switches 10.

At the same time, in conjunction with the movement of the operation knob 19, the display board 15 is also slid to the position ■ and the position II, and depending on the type and selection of remote control by the switch 18, the appropriate display I or II is displayed through the hole. 12, it becomes extremely easy to understand, and it becomes possible to easily carry out error-free remote control.

In addition, since the display board 15 for switching between the displays I and II is slidably provided between the keyboard 9 and the lid 13, the display can be changed immediately in conjunction with switching the switch. can be done, and
This does not get in the way during operation, making it easy to handle.
It is also possible to obtain a device with good operability.

As described in detail above, according to the present invention, the display for inputting instructions is switched using the display board that slides in conjunction with the switching of the remote control signal. It is possible to obtain a remote control device that can generate control signals, has a simple configuration, has an easy-to-understand display, and has good operability.
