Title:
NOISE DETECTION SENSOR AND IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP2002286775
Kind Code:
A
Abstract:
To provide a highly sensitive noise detection sensor capable of detecting the generation state of spark discharge.
This noise detection sensor is equipped with a coil 61 and a diode 62 connected in series to the coil 61. Since the diode 62 is mounted on the coil 61, the detection sensitivity of the noise detection sensor is heightened, to thereby easily detect the state where the spark discharge is generated and image formation is executed scattering an electromagnetic noises on a part where a high voltage of this image formation device is applied.
