摘要：
In a starting and operating apparatus of a high-pressure discharge lamp of the invention, power is supplied to a heater (28) provided in a high-pressure discharge lamp (26) from a battery (l8). The battery (l8) is charged by a charger (l2). The charger (l2) is driven by a power section (l4). The power section (l4) is started by an ON operation of a switch (l6). The switch (l6) is turned on/off synchronously with the operation of a control switch (32). The control switch (32) allows power supply from the battery (l8) to the heater (28) when it is turned on. Therefore, while power is supplied to the heater (28), the battery (l8) is always charged by the charger (l2) and the voltage of the battery (l8) will not be lowered.
