| Zusammenfassung: | A driver apparatus (60, 70, 100) drives aligned light emitting thyristors. Each thyristor includes an anode (A), a cathode (K), and a gate (G). The driver apparatus includes a common terminal (IN), a first resistor (64), a second resistor (65), and a switch (63). Each thyristor is disposed at a first position where the anode is connected to the first potential and the cathode is connected to the common terminal, or a second position where the anode is connected to the common terminal and the cathode is connected to the second potential. The first resistor is connected between the first potential and the common terminal. The second resistor is connected between the common terminal and the second potential. The switch is connected at a third position where the switch is connected between the between the first potential and the common terminal, or a fourth position where the switch is connected between the common terminal and the second potential. |
