It goes without saying that this garage shutter control system can be applied to both configurations of the first and second invention systems.

Next, the configuration of each device used in the system of the present invention will be described more specifically.

FIG. 11 shows a structural example of a wireless transmitter.

The illustrated wireless transmitter A is formed in a thin card type for convenience of carrying, and forms a transmission control circuit unit 10 and is a base plate unit 11 composed of a circuit board PC which is driven by a battery 3. The circuit board P, which is constructed by assembling the cover plate portion 12 on the above, and constitutes the base plate portion 11.
C is a loop antenna 10 formed of a conductive pattern.
a and a control operation switch SW are formed, and the transmission control circuit unit 10 uses a lithium battery or the like as a power source for the CPU.
10A is driven to operate.

The loop antenna 10a converts a control signal generated by the wireless transmission unit 10B in the transmission control circuit unit 10 into a weak radio wave and outputs the weak radio wave, and is formed in a plane as compared with a conventional conductor antenna having a three-dimensional structure. As a result, the wireless transmitter can be made even thinner.

Each of the control operation switches SW is installed on the circuit board PC in such a manner that its operating portion has a positional relationship that matches the convex portion 12b formed on the back surface of the key top piece portion 12a formed on the cover plate portion 12, When the key top piece 12a formed on the cover plate 12 is pressed, the operating portion 1
2b is pushed down, the switch SW is activated,
The control signal is radiated and output from the loop antenna 10a to the receiver side.

The cover plate portion 12 has a structure in which a circuit board PC can be fixed to the cover plate portion 12 with screws 4 or the like, and the battery 3 can be put in or taken out through an opening 12c formed in the rear thereof.
It is formed in a lower open structure having a certain thickness.

The coin-shaped battery 3 has a support plate 5 of a battery case 5 having a pair of legs 5a having locking claws 5b at its tip.
A conductive plate 6 which is housed in a circular arc-shaped hole portion 5d in which c is installed, and which has the same number of comb tooth-shaped convex pieces 6a as the conductive portion 10c formed on the circuit board PC side is placed below the hole portion 5d. The convex portion 6b formed on the conductive plate 6 is brought into contact with the negative electrode side (lower side in the figure) of the battery 3. By doing so, the conductive portion 10c formed on the circuit board PC by selectively changing the contact mode between the comb tooth-shaped convex piece 6a of the conductive plate 6 and the conductive portion 10c is selectively connected to the negative electrode of the battery 3. , And the potential can be fixed to the negative level of the battery 3.

When the battery case 5 is inserted through the opening 12c formed at the rear of the cover plate 12, the locking claws formed at the tips of the legs of the battery case 5 engage with the corresponding locking protrusions of the cover plate. In the state where the battery is housed in this way, the positive electrode side on the upper side of the battery contacts the conductive piece (not shown) formed on the circuit board side, and the negative electrode on the lower side of the battery is the conductive plate. Power is supplied to the circuit board by coming into contact with the conductive pattern of the circuit board through the comb-teeth-shaped convex pieces.

It should be noted that stickers 13 and 14 indicating the type of the wireless transmitter, the function usage method, etc. are attached to the upper surface of the cover plate portion and the lower surface of the base plate portion, respectively. A display 13a showing a key top formed on the cover plate portion is attached to 13, and in front of it,
A transparent window 13b for transmitting the lighting light of the operation display LED provided on the circuit board side is formed.

Further, regarding the contact mode between the comb-teeth-shaped convex piece 6a of the conductive plate 6 and the conductive portion 10c provided on the circuit board PC side, a part of the comb-teeth-shaped convex piece 6a of the conductive plate 6 is broken or brought into contact. Power conductive part 1
It is easily realized by a method of interposing an insulating sheet having holes corresponding to 0c between the battery 3 and the conductive plate 6.

In the example shown in FIG. 12, instead of the three switches SW1 to SW3 shown in FIG. 2, an insulating sheet 7 is used to form the comb tooth-shaped convex pieces 6a of the conductive plate 6 and the conductive portion 10c on the circuit board PC side. By changing the manner of contact with the wireless transmitter A
It is assumed that the tone color pattern of the transmitted notification sound is changed, and FIGS. 13A to 13C show the types of insulating sheets used for such a purpose.

FIG. 13 a) shows that the first, third, and sixth convex pieces 6 a (# 1, 3, 6) of the six comb-shaped convex pieces 6 a of the conductive plate 6 are held by the negative electrode of the battery 3. And FIG. 13 b)
Ha. The first, second, and sixth convex pieces 6a (# 1, 2, 6)
Is held by the negative pole of the battery, and FIG. 13c) shows that the first and sixth convex pieces 6a (# 1, 6) are held by the negative pole of the battery 3, respectively. The tone color pattern of the sound output can be set by various methods without using the switches SW1 to SW3 as shown in FIG.

FIG. 14 shows the configuration of the transmission circuit section oscillation circuit section included in the transmission control circuit.

The wireless transmission unit 10B is configured to include an oscillation circuit 101, a frequency multiplication unit 102 and a loop antenna 10a. In the figure, Q1 is a transistor of a crystal oscillation circuit, and this transistor Q1 is a DC resistance. R
1, R2 is biased, and DC negative feedback is applied by the resistor R3.

The oscillator circuit 101 includes a crystal resonator X, a coil L1,
Although it is configured to oscillate at a frequency determined by the capacitor C1, in order to maintain stable oscillation operation, the capacitor C1 is used.
2, the amount of positive feedback, capacitors C3, C4 and coil L2
The amount of negative feedback is determined by so that stable oscillation is maintained. The output of the oscillation circuit 101 is a capacitor C
6 is added to the transistor Q2 biased by the resistors R4 and R6, and the high frequency of the frequency of the resonance circuit formed by the coil L3 and the capacitor C7 is selectively amplified and supplied to the loop antenna 10a through the capacitors C8 and C10 and the radio signal is supplied. Is emitted as.

Here, the parallel resonance circuit formed by the capacitor C9 and the coil L4 is tuned to the target oscillation frequency and has a low impedance with respect to other frequencies.
It acts as a filter that removes interfering waves.

The capacitor C11 connected to the loop antenna 10a is provided to improve the radiation efficiency of the antenna together with the inductance component of the loop antenna 10a.

When the oscillation circuit section is formed on one surface of the circuit board as described above, it is desirable to form a conductive shield having a conductive plate attached on the back surface of the circuit board except the portion corresponding to the loop antenna 10a. , In such a case, the high frequency magnetic field generated by the high frequency generated by the oscillation circuit part induces an eddy current in the conductive plate, and a magnetic field that tries to block this eddy current is generated, so that the incoming magnetic field is canceled and attenuated. Wave interference can be eliminated.

FIGS. 14A and 14B each show the procedure for forming a conductive shield on a circuit board. In the example of FIG. 14A, double-sided copper foil is attached to both front and back surfaces of an insulating plate. A copper clad laminate P is used. A circuit pattern 11 including a loop antenna 10a is formed on the surface of the double-sided copper-clad laminate P by etching, and necessary electronic components are mounted on the circuit pattern 11 to form a transmission control circuit 10 (see FIG. a)). Then, the conductive shield 11a is formed on the back surface of the laminated plate P, except for the copper foil of the portion except the loop antenna 10a formed on the front surface (see FIG. 11B).

In the example of FIG. 14B, the conductive shield is formed using the single-sided copper clad laminate P '.

The transmission control circuit 10 forms a circuit pattern by etching a copper foil attached to one surface of an insulating plate and mounts necessary electronic components to form the transmission circuit unit 10 (see FIG. 11A).

On the other hand, since the copper foil is not attached to the back surface of the single-sided copper-clad laminate P ', another copper foil is attached to the portion without the loop antenna 10a to form the conductive shield plate 11a.

FIG. 15 is a spectrum showing the oscillation frequency and the electric field intensity of spurious radiation when the above-mentioned conductive shield is not provided on the circuit board, and FIG. 16 is the spectrum when the above-mentioned shield plate is provided on the circuit board. Is shown.

From the comparison of these figures, when the conductive shield is provided,
It can be seen that it is effective in reducing spurious radiation.

Such a conductive shield leaves a copper foil stuck on the surface opposite to the surface on which the loop antenna formed by the conductive pattern is formed when the transmission control circuit is mounted on the circuit board by processing the copper clad laminate. It can be easily formed by a method such as.

When there is no output from B, power is directly sent to the VDD terminal of CPU 20A, but when there is an output from power supply circuit 20B, diode D1 due to RC circuit 20C.
Becomes non-conducting and the output of the power supply circuit 20B is the CPU 20A.
Is sent to the VDD terminal.

The CPU shown in the figure is provided with a control mode output terminal M1 and a registration mode output terminal M2 for controlling the lighting of the mode display lamp 27.
An OR circuit in which resistors R1 and R2 are connected to diodes 1 and M2 via diodes D3 and D4, respectively,
Further, the outputs of the OR circuits are commonly connected, and one display lamp 27 having the other end connected to the power supply is connected.

The resistor R2 interposed on the registration mode output terminal M2 side of the OR circuit is selected to have a smaller value than the resistor R1 interposed on the control mode output terminal M1 side.

With such a configuration, when the receiver B is set to the registration mode, a pulse signal is output from the registration mode output terminal M2, the display lamp 27 blinks according to the cycle of the signal, and the control mode is entered. At this time, the "L" level signal is output from the control mode output terminal M1 and the display lamp 27 lights up.
The value of the current flowing through 7 becomes larger in the registration mode due to the difference between the resistors R1 and R2, so that the confirmation of the registration mode is easy and convenient.

Further, in such a configuration, it is particularly useful when the mode display lamp 27 is a green LED, which has a characteristic that the luminance is more proportional to the current value than the red LED (see FIG. 21).

[Effects of the Invention] The first system of the present invention can provide a simple wireless transmission system in which the user does not need to set the registration mode in addition to setting the ID code.

In the second system, when the ID code is received from the wireless transmitter during the preset registration mode time, the counting of the registration mode time starts again from the beginning. It is more convenient for the system having the above because it is sufficient to operate the next wireless transmitter within a fixed time.

In addition, in the third system in which the brightness of the mode display lamp when blinking in the registration mode is higher than the brightness when lighting in the control mode, the confirmation in the registration mode is easy and reliable.
