Claims (1)
すように、前記第１の回線と前記第２の回線との
間に接続されたトランジスタと、前記第１の回線
が捕捉されたことを検出すると前記トランジスタ
をオン状態とし、前記第１の回線が捕捉されてい
ないことを検出すると前記トランジスタをオフ状
態とするトランジスタ制御手段とを具備すること
を特徴とする叉点回路。 A transistor connected between the first line and the second line so as to connect or disconnect the first line and the second line, and the first line being captured. A cross-point circuit comprising transistor control means that turns on the transistor when it detects that the first line is not captured, and turns the transistor off when it detects that the first line is not captured.
