Noncontact information transmitter

A noncontact information transmitter comprising:

• a first speed optical transmission block comprising a first transmitter side including a first emitter and a first receiver, and a second transmitter side including a second emitter and a second receiver;
• wherein the first emitter transmits a first optical signal to the second receiver across a spatial gap of 0-‥mm and the second emitter transmits a second optical signal to the first receiver across the spatial gap, and wherein the first optical signal and the second optical signal each comprise a serial signal conforming to one of the USB and IEEE 1394 standards, and full duplex transmission is accomplished between the first transmitter side and the second transmitter side;
• and
• a second speed optical transmission block, having a lower transmission speed than said first speed optical transmission block, including a first transmitter side including a first emitter and a first receiver, and a second transmitter side including a second emitter and a second receiver;
• wherein the first emitter transmits a first optical signal to the second receiver across a spatial gap of 0-15 mm and the second emitter transmits a second optic al signal to the first receiver across the spatial gap, wherein the first optical signal and the second optical signal each comprise a serial signal conforming to one of the USB and IEEE1394 standards, and full duplex transmission is accomplished between the first transmitter side and the second transmitter sided.
