| titleOfInvention | Toner level sensor |
| abstract | A toner level sensor detecting the presence, absence, or the level of toner remaining in an electronic copying machine, has a pair of transformers (9a), (9b) with primary and secondary coils (L1a), (L1b) and (L2a), (L2b), respectively, wound around magnetic cores (7a), (7b) with magnetic air gaps, provided so as to operate stably even if the external environmental conditions such as the temperature, moisture, etc., vary. The phases of the outputs of the secondary coils are set alternately opposite to each other when a regulating magnetic unit is positioned in the vicinity of one magnetic air gap and there is toner in the vicinity of the other magnetic air gap, so that the presence, absence, or the level of toner remaining can be determined by detecting phase differences between the outputs of each of the secondary coils by a phase comparator (11). |
