DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a lighting display device of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a lighting display device. The lighting display device 1 is constructed by connecting four lighting display units 2 one by one. As shown in FIG. It is configured for viewing.

The lighting indicator unit 2 is composed of a lighting display section 3 for performing 7-segment display on the display surface 10 shown in FIG. 2 by lighting an LED, an input circuit, a decoder circuit, and a drive circuit of the lighting display section 3 for lighting display. A lighting display control unit 4 for performing lighting display control of the unit 3, an input side connector 6, and an output side connector 7 are provided. The input-side connector 6 and the output-side connector 7 have the same configuration and have four lighting display data signal terminals T1 to T4, four operation command signal terminals D1 to D4, and two power supply terminals V +. ，
V- and are provided.

The lighting display data signal terminals T1 to T4 of the input side connector 6 are connected to the lighting display control section 3 and the lighting display data signal terminals T1 to T4 of the output side connector 7, respectively. Input side connector 6
1 is connected to the lighting display control unit 4, and the remaining operation command signal terminals D2 to D4 of the input side connector 6 and the operation command signal terminals D1 to D3 of the output side connector 7 are connected. Further, the power supply terminals V + and V- of the input side connector 6 are connected to the power supply terminals V + and V- of the output side connector 7, and are connected to the lighting display control unit 4 to perform lighting display. The container unit 2 is configured.

Each of the four lighting indicator units 2 configured as described above is connected in succession with the same terminals of the output side connector 7 and the input side connector 6, respectively, and is the first one. 4 signal lines TL1 from the control device to the data signal terminals T1 to T4, the operation command signal terminals D1 to D4, and the power supply terminals V + and V− of the input side connector 6 of the lighting indicator unit 2 of FIG. TL4,
4 signal lines DL1 to DL4, 2 power supply lines V
The lighting display device 1 is configured by connecting L1 and VL2, respectively. In the lighting display device 1 configured as described above, a lighting display data signal, a predetermined operation command signal, and a power source from the control device are supplied to the respective lighting indicator units 2.

The lighting display operation in the above embodiment will be described below.

For example, in the lighting display device 1, "123
4 ”is displayed, the signal lines TL1 to TL1 from the control device are displayed.
First, when the lighting display data signal of "1" is given via the TL4 and the operation command signal is given via the signal line DL1, the lighting display data signal is given to the display control section 4 of each lighting indicator unit 2. Since the operation command signal is given only to the display control unit 4 of the first lighting indicator unit 2, only the first lighting indicator unit 2 displays "1" on the lighting indicator unit 3. The display control unit 4 of the first lighting display unit 2 latches the given lighting display data signal to the lighting display unit 3 side based on the operation command signal, whereby the lighting display unit 3 displays “1”. The lit display continues.

Next, from the control device, the signal lines TL1 to T
When the lighting display data signal of "2" is given through L4 and the operation command signal is given through the signal line DL2, the lighting display data signal is given to the display control section 4 of each lighting indicator unit 2, but the operation is performed. Since the command signal is given only to the display controller 4 of the second lighting indicator unit 2, only the second lighting indicator unit 2 continuously displays "2" on the lighting indicator 3. In the above description, the operation command signal given to the first lighting indicator unit 2 via the signal line DL2 changes from the terminal D2 of the input side connector 6 to the output side connector 7 in the first lighting indicator unit 2. It is sent to the terminal D1, further sent to the terminal D1 of the input side connector 6 of the second lighting indicator unit 2, and then sent to the display control unit 4 of the second lighting indicator unit 2.

Then, in the same manner as above, the lighting display data signal of "3" is given from the control device through the signal lines TL1 to TL4, the operation command signal is given through the signal line DL3, and the signal lines TL1 to TL4 are further supplied. The lighting display data signal of "4" is given through the signal line DL4 and the operation command signal is given to the lighting display data signal of "4". “4” is displayed on the lighting display unit 3 of the lighting display unit 2, respectively, so that “123” is displayed in the entire lighting display device 1.
4 ”is displayed.

FIG. 3 shows another embodiment of the lighting display device 1. In this embodiment, one serial signal data line SL from the control device is connected to the first lighting display unit 2, and further, The lighting indicator units 2 are sequentially connected by serial signal data lines.

The input-side connector 6 and the output-side connector 7 of each lighting indicator unit 2 are constructed by providing one lighting display data terminal T and a pair of power supply terminals V + and V-. There is. The reception processing unit 12 is connected to the lighting display data terminal T of the input side connector 6 and is provided in the preceding stage of the lighting display control unit 4, and the reception processing unit 12 and the lighting display data terminal T of the output side connector 7 are connected. The transmitter 13 is provided between them. When the lighting display serial data signal with the designated code of the lighting indicator unit 2 is transmitted, the reception processing unit 12 first determines whether the code is that of the lighting indicator unit 2 itself. If it is its own, the subsequent lighting display serial data is parallelized and sent to the display control unit 4, and if it is not its own, the next lighting display unit 2 with the serial data signal as it is from the transmission unit 13. Send to.

Then, such a lighting indicator unit 2
In the state where the respective lighting side display data terminals T of the respective output side connector 7 and the input side connector 6 are connected to each other and power is supplied to the respective lighting display unit 2 by the power supply lines VL1 and VL2, When a serialized lighting display data signal is given from the control device to the lighting display data terminal T of the lighting indicator unit 2 of No. 1, the corresponding lighting display is sequentially performed in each lighting indicator unit 2 designated by the code in the signal. The data is captured and the lighting display is performed in each lighting indicator unit 2.

[0022]

As is apparent from the above description, in the invention of claim 1 of the present invention, the lighting display units are sequentially connected, and the lighting display data from the input side connector of the lighting display unit on one end side is transmitted. Since the lighting display is performed on all the lighting display units connected by the input, the wiring to this lighting display device only needs to be performed on the lighting display unit on one end side, which can reduce the number of wirings. As a result, wiring work in the lighting display device is facilitated, the wiring space is reduced, the device is downsized, and the cost can be reduced.

According to the second aspect of the present invention, each of the lighting display units is sequentially connected by the input / output connectors of each other, and the lighting display units on one end side are simply wired from the control unit to display the respective lighting displays. It is possible to configure a lighting display device capable of displaying in a lighting unit, and by using a lighting display unit having the same configuration, a lighting display device with a reduced number of wires can be obtained. Wiring work in the device is facilitated, the wiring space is reduced, the device is downsized, and the cost can be reduced.
