Title:
SIGNAL TRANSMITTER
Document Type and Number:
Japanese Patent JP2994500
Kind Code:
B2
Abstract:

PURPOSE: To provide a signal transmitter which can rapidly transmit information by parallel transmission and stably transmits information without being prevented transmission owing to dirt, etc., in regard to the signal transmitter which can transmit a signal between a transmitting part and a receiving part, which are provided in the state of non-contact.
CONSTITUTION: Plural individual magnetic paths 11 to 14, 51 to 54 and common magnetic paths 16 and 56 connected to them are disposed on the sides of transmission/reception parts 10 and 50 so as to face each other and the common magnetic paths 16 and 56 are provided with a alternating magnetic flux adding means 7 which gives an alternating magnetic flux. Besides, the respective individual magnetic paths 11 to 14 on the side of the transmission part 10 are provided with electrical magnetic conversion means 21 to 24 modulating the magnetic flux density of the individual magnetic paths 11 to 14 by inputting an electrical signal. Then, the respective individual magnetic paths 51 to 54 on the side of the receiving part 50 are provided with magnetic electrical conversion means 61 to 64 converting the change of the magnetic flux density of the respective individual magnetic paths 51 to 54.
