FIG. 4 shows a view of the controller L1 as viewed from the back. FIG. 4 shows the modular outlet 62 and the switch 66 of the device number setting unit. As shown in FIG. 4, the modular outlet 62 is of a double type. The signal line Q1 is connected to this modular outlet. As described above, this signal line Q1 is composed of three lines. In the case of the present embodiment, each of the modular outlets 62 is a 6-pin type modular outlet, and two pins are used for connecting the signal line Q1. The details are shown in FIG.

As shown in FIG. 5, in the dual modular outlet 62, the first and second pins of each module are used for a power supply line. Pins 3 and 4 are used for ground lines. The fifth and sixth pins are used for signal lines. This wiring method is similarly applied to the zone controller S.

A modular outlet of this type has the same shape as a modular outlet for a telephone line. Therefore, there is a possibility that a telephone line modular is inserted by mistake.

No voltage is applied to the controller L side. Therefore, there is no possibility that the circuit of the controller L is destroyed. Also, no voltage is applied to the telephone line side.

In the actual construction, a protective cover should be attached to prevent dust and dust from entering the terminal body, and precautions should be noted here so as not to cause erroneous wiring.

Even if the telephone line is short-circuited as described above, since the telephone exchange has an internal resistance, the telephone line is not damaged. Also, as shown in FIG. 5, the two modular outlets are connected in parallel and have the same contents. Therefore, either of the modular insertions may be used. The extension or branching of the signal line can be easily carried out using the modular terminal body even if it is embedded. In addition, since two identical modular units are arranged in parallel and both are electrically in the same mode, there is no error in the wiring work of the extension work, and the work can be completed in a short time. Furthermore, since this modular is versatile, there is an effect that parts procurement can be easily performed. Also, since the two parallel modular units have the same contents, there is no need to consider the order of connection when connecting the zone controller S, the controller L1, and the control unit P1. There is also an effect. That is, the control unit P1, the zone controller S, and the controller L1 can be connected in this order.
1. It is also possible to connect in order of the zone controller S.

Referring to FIG. 6, front cabinet 68 has a rectangular opening at the center thereof.

The front cabinet 68 is attached to the resin molded product by inserting and engaging the claws 70 into the openings 58 of the resin molded product of the controller L1.

Referring to FIG. 8, on the front of controller L 1, a decorative cover 72, which is a decorative ornament for decorating between the background of the wall and front cabinet 68, exposes printing sheet 40. It is mounted using screws 78.
Then, the controller L1 is connected to the JI
It is fixed to the switch box 74 of the SC 8336.
The switch box 74 is installed by being embedded in a wall. Note that the signal line Q1 is drawn out from the entrance 76 on the back of the controller L1.

[Second Embodiment] FIG. 12 shows a print sheet of a controller L1 'according to a second embodiment of the present invention. Referring to FIG. 12, this print sheet 180 includes key sheets 162, 164, 166, 168, 170, and 17
2 (key sheets 22, 24, 26, 2 in FIG. 1 respectively)
(Corresponding to 8, 30, and 32) are printed, and further, there is a light-emitting window 170 formed so as to display a light-emitting element according to the slat shape of the blind. FIG. 13 is a front view of the display opening from which the print sheet 180 has been removed. In FIG. 13, the key top 18
2, 184, 186, 188, 190 and 192 are the key tops 42, 44, 46, 48, 5 in FIG.
0 and 52. The nail 196 is the nail 70 of FIG.
Corresponding to This controller L1 'is further provided in FIG.
Has an opening 194 formed in the same shape as the light emitting window 170. The opening 194 is formed by imitating the corresponding slat shape of the blind at the time of opening and closing, and the LED is disposed behind the opening 194 as described above.

When the printed sheet 180 shown in FIG. 12 is pasted on the display opening having the shape shown in FIG. 13, and the LED is made to emit light through the opening and the display window according to the opening / closing degree of the slat, the opening / closing degree of the slat is changed. LE of the shape part according to
D light is displayed. Since the degree of opening and closing of the slat is represented by the shape of the slat corresponding to the degree of opening and closing, it is possible to intuitively understand the display of the degree of opening and closing of the slat even without an auxiliary display by printed matter as in the first embodiment. . Note that the shapes of the display opening and the display window shown in FIGS. 12 and 13 can be considered to be the same shape (shape when the slat is viewed from the side) having a different direction or inclination depending on the angle of the corresponding slat. However, different shapes can be used according to the angles of the corresponding slats. Of course, these shapes, directions or angles can be arbitrary as long as the shape of the slat can be intuitively grasped.

As described above, according to the present invention, the open / closed state of the slat is displayed by the light emitting state of the display elements arranged in the vertical direction. In addition, the light emitting window of the display element at that time has the same shape having a different direction or inclination depending on the angle of the corresponding slat, or has a different shape depending on the angle of the corresponding slat. Therefore, the degree of opening and closing of the slat can be intuitively known. Furthermore, by displaying the degree of opening and closing of the slats with a display element and displaying the degree of opening and closing correspondingly in a printed matter, the open / closed state of the slats can be confirmed more clearly and without misunderstanding. Further, by changing the ink of the printed matter in the portion corresponding to the display window of the printed sheet on the light emitting element to various colors, it is possible to variously change the light emitting display indicating the degree of opening and closing of the slat. For example, by selecting a color close to the actual blind, it is possible to express a sense of unity with the blind. Further, by selecting a print sheet suitable for the installation location, it is possible to select a print sheet having various colors as a print sheet, and to achieve matching between the controller and the surrounding environment.

The present invention is not limited to the above-described embodiments, and it goes without saying that various changes can be made within the scope of the claims.
