切替に手間がかかるという問題があった。(2) Conventional technology and problems Conventionally, display systems installed in stadiums, etc. are as shown in Figure 1 (
As shown in a), connect the display panel (11~In) to the external connector (
Wired operation panel (21-2n) via 31-3n)
A system has been implemented in which multiple display data are transmitted and controlled from multiple operation panels by switching connections between external connectors. For example, in Figure 1 (
As shown in b), all the display panels (11
-In), external connectors (31 to 3'
n) as shown in the figure, and when controlling the operation panel and display panel one-on-one as shown in Figure 1 (C), connect each external connector as shown in the figure. It's here. However, this method is particularly problematic in terms of safety and aesthetics, as it requires running a large number of cables around the floor when a large number of score display boards are installed, and external connectors are not suitable. There was a problem in that it took time and effort to switch because it was installed on the wall inside the venue.

Each display panel includes a first transmitter that transmits a signal and a second transmitter that transmits a dedicated frequency used for each individual operation panel, and each display panel has a first receiver that receives the common frequency and a second transmitter that transmits a dedicated frequency that is used for each individual operation panel. a second receiver that receives a dedicated frequency, selects the frequency of each of the first and second transmitters on the operation panel, and transmits wirelessly 1J.
This can be accomplished by providing a line switching system characterized by controlling a predetermined display panel.

As shown in FIG. 2(a), each of the operation panels has a common frequency f. It is equipped with a first transmitter Tx that transmits a signal and a second transmitter T2 that transmits a dedicated frequency f1 used for each operation panel, and the output of these transmitters is controlled by a predetermined switching means S%C. The screen can be switched according to the display panel you want to display. On the other hand, each of the display panels has a first receiving nucleus for receiving the common frequency fo from the first transmitter 1, and a second receiving nucleus for receiving the dedicated frequency fi assigned to each individual display panel. Equipped with functions.

シ各々表示を行う。FIG. 2(b) shows a case where all the display panels (11-inch) are controlled by one operation panel 22, and all the display panels are connected to the first receiver which receives the common frequency fo. works. FIG. 2(C) shows a case where the operation panel and the display panel are used in a one-to-one manner, where the operation panel 21 transmits the dedicated frequency f1 and the display panel 11 is used for the second receiving core that receives the dedicated frequency f1. use. Similarly, 12 and 22, and in and 20 are displayed as pairs.
第２図（ｄ）は操作盤側で共通周波数ｆｏを送信するも

することができ他の涙示盤はｆｏを受信し表示する。Figure 2 (d) shows a case where the operation panel side transmits the common frequency fo and the dedicated frequency f1. In this case, the display panel side receives the dedicated frequency preferentially. Since the receiver is configured as follows, the display panel for receiving io and the display panel for receiving fi can be separated by N. That is, if only the operation panel 2n transmits the dedicated frequency 13, the corresponding display panel 1n can receive and display f3, and the other display panels can receive and display fo.
