Abstract

PURPOSE:To shorten a remote control signal and to speed up response speed at a receiving part side by outputting a change-over control signal by a mode change-over switch and obtaining a change-over mode and the operating content of an operating button by the control signal of an operating button at a receiving part side. CONSTITUTION:With switching a mode change-over switch 12, an ON detecting circuit 15 and an OFF detecting circuit 16 send a signal to a microcomputer 17 for the control signal and a mode change-over switch control signal 19 are outputted from an oscillator 18. With depressing an operating button 14, a data code is sent to the microcomputer 17 for the control signal and the oscillator 18 outputs the data code as a control signal 19. The control signal can be processed in a short time outputting the same signal even when the operating button is used as other different operation.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to remote control devices, and more particularly to improvements in remote control devices for wireless keyboards, televisions, and video tape recorders.

Conventional technology Figure 3 shows television and videotape recorders (hereinafter '').
1 shows a remote control device (hereinafter abbreviated as remote control) 1 for an electronic device that can select each mode (abbreviated as /TR). Incidentally, FIG. 4 shows a block diagram of FIG. 3.

The remote control 1 has a mode selector switch 12 that allows
Remote control of each mode of television and VTR can be selected. Each mode is selected by the mode changeover switch 12, and the control signal microcomputer 17 generates a control signal 19 corresponding to each operation of the mode changeover switch 12 and each operation button 14. The control signal 19 is configured to be transmitted to the receiver side of the main body of the electronic device via an oscillator 18 that modulates light or ultrasonic waves.

FIG. 6 shows the tie ε77 diagram of FIG. 3, and the above control signal 1
9 is a device selection code (hereinafter abbreviated as a custom code) for selecting a device to be remotely controlled such as a television or VTR, and a code (hereinafter abbreviated as a data code) corresponding to the pressed operation button 14; When this is switched, the power stam code is switched and each mode of remote control can be selected. In addition, a is mode changeover switch 1
2 is the output signal, b is the output signal of the operation button, and C is the control signal. In the example in Figure 5, the custom code "oooooo"
``television mode'' ol.

oO" represents VTR mode, data code 1'00
0010" indicates a control signal corresponding to the channel 1 operation button. However, this has the disadvantage that when the channel 1 operation button is pressed, the custom code and data code are always output as a pair, resulting in a large number of control signals.

By the way, the operation button 14 of the wireless keyboard 2o, which is an input device for the OA, has the number 5 as shown in FIG.
The number 5 is used for two different operation contents: and tick mark.
To input a tick mark, press the operation button 14, and to input a tick mark, press the operation button while holding down the mode switch button 12 (specifically, the 5hift key).The control signal is as shown in Figure 6. Similarly, the code is switched and transmitted.

Problems to be Solved by the Invention In such a conventional configuration, when an operation button is pressed to output a control signal, the code of the control signal is changed and transmitted using a mode changeover switch, so there is a drawback that the number of control signals increases. Ta.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a remote control that outputs a switching control signal using a mode switching switch and simplifies the control signal using operation buttons.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes a mode changeover switch ON timing/OFF timing detection circuit in the remote controller, outputs a predetermined control signal, and then outputs a predetermined control signal. Detects mode switching and uses the control signal from the operation button to
This is used to obtain the switching mode and operation details of the operation buttons.

Effects of the present invention With the above-described configuration, the code length of the remote control control signal can be shortened, the control signal can be transmitted at high speed, and the control response speed on the receiving section side can be increased. Therefore, decoding on the receiving unit side can also be simplified.

Embodiment FIG. 1 is a block diagram showing an embodiment of the remote controller of the present invention. In FIG. 1, 12 is a mode selection switch;
14 is an operation button, 16 is a mode changeover switch ON timing detection circuit (hereinafter referred to as ON detection circuit), and 16 is a mode changeover switch OFF timing detection circuit (hereinafter referred to as ON detection circuit).
(abbreviated as OFF detection circuit), which includes a control signal microcomputer 172 and an oscillator 18. It has a control signal 19.

First, when the mode changeover switch 12 is switched, the ON detection circuit 15. The OFF detection circuit 16 operates, sends a signal to the control signal microcomputer 17, and the oscillator 18 outputs a mode changeover switch control signal 19. When the operation button 14 is then pressed, the data code is sent to the control signal microcomputer 17, and the oscillator 18 outputs the data code as the control signal 19.

FIGS. 2a to 2c show a mode changeover switch 12, an operation button 14. 3 is a timing diagram of control signal 19. FIG. In the example shown in FIG. 2, when the mode selector switch 12 is turned on, the custom code "o" is activated.

000'' is output, and when the mode changeover switch 12 is turned OFF, the custom code ``01000'' is output, and when the operation button is pressed, only the data code ``000010'' is output.

Therefore, when the mode change switch is changed, the mode change signal is output as a control signal, and even if other operation buttons have different operation contents, by outputting the same signal, the control signal can be changed for a short time. It can be done.

In the above description, the present invention is applied to the mode changeover switches of televisions and VTRs, but the present invention can also be applied to the case of using the shift key and other operation switches of the zero mode input device.

Effects of the Invention As described above, according to the present invention, the control signal can be simply configured to be short, the response speed can be increased, and the battery life can be extended, which is extremely practical. Useful.
