Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a control device for electronic information equipment that controls the supply of power supply voltage to a plurality of electronic information equipment and the switching of transmission of information signals between them.

In conventional control devices for electronic information equipment, the remote controller is equipped with a power button and multiple mode selection buttons, and a remote control signal based on the operation of these selection buttons is transmitted on a signal medium such as infrared rays, ultrasonic waves, or radio waves. send,
This transmitted signal is received by the control device main body,
Based on this received signal, supply of power supply voltage to a plurality of electronic information devices and switching of transmission of information signals between them are controlled.

In this case, when the power button is turned on, power supply voltage is supplied to all electronic information devices, and when the power button is turned off, power supply voltage is cut off to all electronic information devices. Furthermore, when one of the multiple mode selection buttons is operated while the power button is turned on, multiple electronic information devices in the group corresponding to that mode are activated, and the The signal switching means are switched so that a network for transmitting information signals between them is formed. For example, if the FM radio mode is selected, the FM radio tuner and amplifier are activated, and the radio audio signal from the FM radio tuner is supplied to the audio amplifier.

In this way, in conventional control devices, when you select a mode and then cancel it, you press the power button →
You have to operate the mode selection button → power button. Therefore, when selecting a certain mode, it is necessary to operate two operation buttons, which has the disadvantage that operation is troublesome.

Furthermore, conventional control devices have the disadvantage that when a certain mode is selected, power supply voltage is also supplied to electronic information devices unrelated to that mode, resulting in wasted power consumption.

In view of this, the present invention provides that, by simply operating a mode selection operator corresponding to each of a plurality of modes, power supply voltage is supplied only to a plurality of electronic information devices belonging to a group corresponding to that mode, and the supply voltage is is stopped, the signal switching means is switched so that a network for transmitting information signals among a plurality of electronic information devices belonging to the group is formed, and a plurality of electronic information devices belonging to a group corresponding to another mode are switched. This paper attempts to propose a control device for electronic information equipment in which the supply of power supply voltage to the information equipment is stopped.

Each time the switch SW-TC is turned on, a tape recorder mode selection signal (positive pulse, logic value "1") is generated from the midpoint of the connection between the switch SW-TC and the resistor R.

Next, the control signal generating means 31 will be explained.
When selecting the TV mode, the audio amplification device 1,
The power supply voltage is supplied to the television monitor receiver 2 and the television tuner 3, and the supply thereof is stopped. Therefore, a flip-flop circuit FF-TV ₁ for TV mode power switching control is provided, and the TV mode power switching control signal (ON signal is "1" and OFF signal is "0") from its non-inverting output terminal is transmitted separately. The power switch means S-A, S-VM, S-
It is supplied to the base of each transistor Q of VT.

Further, when selecting the tape recorder mode (especially when re-displaying), the power supply voltage is supplied to the tape recorder 4 and the audio amplifying device 1, and the supply thereof is stopped. Therefore, a flip-flop circuit FF-TC ₁ for tape recorder mode power supply switching control is used.
The TV mode power switching control signal (on signal is "1",
(the off signal is "0") is connected to the power switch means S-A, S- through separate damper diodes D.
It is supplied to the base of each transistor Q of TC.

In FIG. 3, gate circuits (AND circuits and OR circuits) are marked with the symbol G, and the symbols TV, TV, etc. are added via a hyphen depending on whether they relate to the TV mode or the tape recorder mode. In addition to adding TC, each corresponding gate circuit has
TV and TC are shown with the same subscript. or,
Flip-flop circuits FF-TV ₂ and FF-TC ₂ are provided in association with the television mode and tape recorder mode, respectively, for storing the states of their own and other mode selection signals.

Furthermore, the signal line L ₁₁ ~ corresponds to 4 modes.

L ₁₃ and L ₁₄ are supplied with respective non-inverting outputs of similar flip-flop circuits in the other two modes.
The signal lines L ₂₁ and L ₂₂ are supplied with the non-inverted outputs of the flip-flop circuits FF-TV ₂ and FF-TC ₂ , respectively, and the signal lines L ₂₂ and L ₂₃ are supplied with the non-inverted outputs of the flip-flop circuits in the other two modes, respectively. Each non-inverting output is provided.

Since the logic circuits for each mode for generating the power switching control signal for each mode based on each mode selection signal generated by the mode selection signal generation means 30 are the same, the TV mode will be taken as an example.
The structure and operation of the logic circuit will be described below in relation to the tape recorder mode and the other two modes.

First, when a TV mode selection signal is generated by operating the TV mode selection button 21 and turning on the switch SW-TV when none of the four modes are selected (the first
case) will be explained. At this time, all the signals on the initial signal lines _L11 to _L14 are "0". Therefore, the non-inverted output Q of the flip-flop circuit FF- _TV1 is "0". Therefore, the AND circuit G-TV ₁ is on and the AND circuit G-TV ₂ is off.

When the first television mode selection signal ``1'' is generated, it is supplied to the set input terminal of the flip-flop circuit FF-TV <sub>1</sub> through the AND circuit G-TV <sub>1</sub> , and its non-inverted output Q becomes ``1''. It becomes an on signal. For this reason, the signal line L ₁₁
The signal becomes "1", but the value signal line L ₁₂ ~
The signal at _L14 remains "0". Therefore, AND circuit G-TV ₁ is turned off, and AND circuit G-TV _{2 is} turned off.
turns on.

When the second television mode selection signal "1" is generated, it passes through the AND circuit G-TV ₂ and comes to the input side of the AND circuit G-TV ₃ . signal line
Since the signals _L12 to _L14 are all "0", the AND circuit G- _TV3 is on, and the second TV mode selection signal "1" is output from this AND circuit G- _TV3.
After passing through the OR circuit G- _TV5 , it is supplied to the reset input terminal of the flip-flop circuit FF- _TV1 , and its non-inverted output Q becomes "0", which becomes an off signal. Therefore, the AND circuit G-
TV ₁ is on, AND circuit G-TV ₂ is off,
Return to the original state.

Thus, each time the TV mode selection signal "1" is generated, the flip-flop circuit FF- _TV1 is inverted;
An on signal and an off signal are alternately output from the non-inverting output terminal.

Next, when at least one mode other than the TV mode is selected among the four modes (for example, when the tape recorder mode is selected), the TV mode selection button 21 is pressed.
A case (second case) in which a television mode selection signal is generated by operating the switch SW-TV and turning on the switch SW-TV will be described. At this time,
Initially, among the signal lines _L11 to _L14 , the signal on signal line _L12 is "1" and the signals on the other signal lines are "0". Therefore, the flip-flop circuit FF-TV ₁
The non-inverted output Q of is "0". Therefore, the AND circuit G-TV ₁ is on and the AND circuit G-TV ₂ is off. Also, flip-flop circuit FF-TC ₁
The non-inverted output Q of is "1".

When the first television mode selection signal ``1'' is generated, it is supplied to the set input terminal of the flip-flop circuit FF-TV <sub>1</sub> through the AND circuit G-TV <sub>1</sub> , and its non-inverted output Q becomes ``1''. It becomes an on signal. For this reason, the signal line L ₁₁
The signal also becomes "1". The signal on signal line _L12 is "1", and the signal on signal lines _L13 and _L14 is "0".
It remains as it is. Therefore, the AND circuit G-TV ₁ is turned off and the AND circuit G-TV ₂ is turned on.

When the second television mode selection signal "1" is generated, it passes through the AND circuit G-TV ₂ and comes to the input side of the AND circuit G-TV ₃ .

However, since the signal on the signal line L ₁₂ (L ₁₃ and L ₁₄ are also possible) is "1", the AND circuit G-TV ₃ is off. On the other hand, this second television mode selection signal "1" passes through the AND circuit G-TV ₂ and comes to the input side of the AND circuit G-TV ₉ . In this case, since the signal line L ₁₂ (L ₁₃ and L ₁₄ are also possible) is signal "1", this is passed through the OR circuit G-TV ₄ to the AND circuit G-
Since the signal is supplied to TV ₉ , the AND circuit G-TV ₉ is on. Therefore, the second television mode selection signal "1" also passes through this AND circuit G-TV ₉ and comes to the input side of AND circuits G-TV ₆ and G-TV ₇ . In this case, the flip-flop circuit FF−
Since the non-inverted output Q of TV ₁ is "1", this Q=
When "1" is obtained, it is supplied to the set input terminal of the flip-flop circuit FF-TV ₂ through the OR circuit G-TV ₁₀ , and its non-inverted output Q is "1". −
TV ₆ is off and AND circuit G-TV ₇ is on.
Therefore, the second television mode selection signal passes through this AND circuit G- _TV7 and is supplied to the reset input terminal of the flip-flop circuit FF- _TC1 through the OR circuit G- _TC5 , so that its non-inverted output Q
is inverted from "1" to "0", which becomes an off signal for the tape recorder mode. Therefore, the signal on the signal line _L12 becomes "0". Furthermore, the signal line
The signal of L ₁₁ remains "1" and the signals of signal lines L ₁₃ and L ₁₄ remain "0". Also, flip-flop circuit
Since the non-inverted output Q of FF-TV ₁ remains "1", AND circuit G-TV ₁ is off and AND circuit G-TV ₂ is on.

When the television mode selection signal "1" is generated for the third time, it passes through the AND circuit G-TV ₂ and comes to the input side of the AND circuit G-TV ₃ . signal line
Since the signals _L12 to _L14 are all "0", the AND circuit G- _TV3 is on, and the third TV mode selection signal "1" is output from this AND circuit G- _TV3.
After passing through the OR circuit G- _TV5 , it is supplied to the reset input terminal of the flip-flop circuit FF- _TV1 , and its non-inverted output Q becomes "0", which becomes an off signal. Therefore, the AND circuit G-
TV ₁ is on, AND circuit G-TV ₂ is off,
Returning to the initial state of the first case described above.

Next, when a plurality of modes among the four modes, for example, television mode and tape recorder mode, are selected and the reproduced audio signal from the tape recorder 4 is being supplied to the audio amplifier 1, the television mode is selected. Operate button 21 to switch
A case (third case) in which a television mode selection signal is generated by turning on SW-TV will be described. At this time, initially the signal line L ₁₁ ~
The signals of signal lines L ₁₁ and L ₁₂ of L ₁₄ are "1",
The signals on signal lines L ₁₃ and L ₁₄ are "0". Therefore, the flip-flop circuits FF-TV ₁ , FF-TC ₁
Both of the non-inverted outputs Q are "1". Therefore,
AND circuit G-TV ₁ is off, AND circuit G-
TV ₂ is on.

When the first TV mode selection signal "1" is generated, the signal switching circuit MK is switched so that the audio signal from the TV tuner 3 is supplied to the audio amplifier 1, and the first TV mode selection signal "1" is switched. ” passes through the AND circuit G-TV ₂ ,
It comes to the input side of AND circuit G-TV ₂ . However, since the signal on the signal line L ₁₂ (L ₁₃ and L ₁₄ are also possible) is "1", the AND circuit G-TV ₃ is off. On the other hand,
This first television mode selection signal "1" passes through the AND circuit G-TV ₂ , and then the AND circuit G-TV _9.
It also comes to the input side. In this case the signal line L ₁₂ (L ₁₃ ,
Since the signal of _L14 is "1", it is supplied to the AND circuit G-TV 9 through the OR circuit G-TV ₄ , so _{the AND circuit G-TV 9 is} on.
Therefore, the first television mode selection signal "1" also passes through this AND circuit G-TV ₉ and comes to the input side of AND circuits G-TV ₆ and G-TV ₇ . In this case, since the non-inverted output Q of the flip-flop circuit FF-TC ₁ is "1", when this Q = "1" is obtained, it is sent to the set input terminal of the flip-flop circuit FF-TC ₂ through the OR circuit G-TC ₁₀ . is supplied, and its non-inverted output Q is "1",
Since this non-inverted output Q = "1" is supplied to the reset input terminal of the flip-flop circuit FF-TV ₂ through the OR circuit G-TV ₈ , the non-inverted output Q is "0". Therefore, the AND circuit G-TV ₆ is on and the AND circuit G-TV ₇ is off. Therefore, the first television mode selection signal passes through this AND circuit G- _TV6 and is sent to the OR circuit G.
−TV ₁₀ through flip-flop circuit FF−TV ₂
The non-inverting output Q is inverted from "0" to "1". At this time, the signals on the signal lines L ₁₁ and L ₁₂ remain at "1", and the signals on the signal lines L ₁₃ and L ₁₄ remain at "0". Furthermore, the non-inverted outputs Q of the flip-flop circuits FF-TV ₁ and FF-TC ₁ both remain at "1". Therefore,
AND circuit G-TV ₁ is off, AND circuit G-
TV ₂ remains on.

When the second television mode selection signal "1" is generated, it passes through the AND circuit G-TV ₂ and comes to the input side of the AND circuit G-TV ₃ . However, since the signal on the signal line L ₁₂ (L ₁₃ and L ₁₄ are also possible) is "1", the AND circuit G-TV ₃ is off. On the other hand, this second television mode selection signal "1" passes through the AND circuit G-TV ₂ and also comes to the input side of the AND circuit G-TV ₉ . In this case the signal line L ₁₂ (L ₁₃ ,
Since the signal of _L14 is "1", it is supplied to the AND circuit G-TV 9 through the OR circuit G-TV ₄ , so _{the AND circuit G-TV 9 is} on.
Therefore, the second television mode selection signal "1" also passes through this AND circuit G-TV ₉ and comes to the input side of AND circuits G-TV ₆ and G-TV ₇ . In this case, the non-inverted output Q of the flip-flop circuit FF-TV ₂ is "1", so the AND circuit G-TV ₆ is off and the AND circuit G-TV ₇ is on. Therefore, the second television mode selection signal also passes through this AND circuit G- _TV7 and is sent to the OR circuit G.
−TC ₅ through flip-flop circuit FF−TC ₁
, the non-inverted output Q is inverted from ``1'' to ``0'', which becomes the tape recorder mode off signal. Therefore, the signal on the signal line _L12 becomes "0". still,
The signal on signal line L ₁₁ is "1", the signal on signal line L ₁₃ ,
The signal at _L14 remains "0". Furthermore, since the non-inverted output Q of the flip-flop circuit FF- _TV1 remains at 1, the AND circuit G- _TV1 is off and the AND circuit G- _TV2 is on.

When the television mode selection signal "1" is generated for the third time, it passes through the AND circuit G-TV ₂ and comes to the input side of the AND circuit G-TV ₃ . signal line
Since the signals _L12 to _L14 are all "0", the AND circuit G- _TV3 is on, and the third TV mode selection signal "1" is output from this AND circuit G-TV3.
After passing through TV ₃ as well, it is supplied to the reset input terminal of flip-flop circuit FF-TV ₁ through OR circuit G-TV ₅ , and its non-inverted output Q becomes "0", which becomes an off signal. Therefore, the AND circuit G-TV ₁ is turned on and the AND circuit G-TV ₂ is turned off, returning to the original state in the first case described above.

Although not shown, when the all-off mode selection operation button 20 is operated, all the mode power switching flip-flop circuits are reset, and the signal switching means MK is also reset.
