。Conventional Structure and Problems Conventionally, when displaying the cooking process using light emitting elements in a jar rice cooker, as shown in FIG. Drive circuit 5.6. γ
were connected to each other, and a light emitting element 8, 9.10 was connected to each drive circuit 5, 6, 7, respectively. This light emitting element 8.
9.10 is connected to the power supply Vcc via resistors 11.12.13. Based on the output of the control circuit 1, the drive circuits 5, 6 . The light-emitting elements 8, 9, and 10 are illuminated by the 4-section gamma force. This conventional configuration requires the same number of light-emitting elements as the cooking process, and as the cooking process becomes more complicated, the number of light-emitting elements increases, resulting in an increase in cost.

At 2.23.24, a signal corresponding to the cooking process is output, and in the first cooking process, the output signal of the output terminal 22 repeats High and Low, and as a result, the collector output of the transistor 28 also repeats High and Low. This causes the light emitting element 34 to blink. In the second cooking process, the output signal of the output terminal 23 repeats high and low,
As a result, the collector output of the transistor 29 also repeats High and Low until the light emitting element and
