Title: Data transmission equipment for portable terminal equipment
Inventor: SANO SHO
IPC: H04B10/071
Filed: 1988-08-16
Abstract: PURPOSE:To realize data transmission without shortening the service life of a battery by arranging each pair of light emitting devices and light receiving devices at a position where a reflected light or a transmissive light of a light beam which is made incident on a liquid crystal indicator from the light emitting device is made incident on the light receiving device. CONSTITUTION:A reader 1 is provided with a pair or plural pairs of light emitting devices 5 and light receiving devices 6 on its inside, and placed in a position where the reflected light or a transmission light of a light beam which is made incident on the liquid crystal indicator 3 of a terminal equipment 2 from the light emitting device 5 is made incident on the light receiving device 6. As a result, a bit pattern corresponding to transmission data is displayed on an indicator 2. By reading its bit pattern by the light emitting device 5 and the light receiving device 6, a data transmission is executed by non-contact. In such a manner since power required for driving the indicator 3 is extremely small, the data transmission can be executed without shortening the service life of a battery of the equipment 2.
