Abstract

PURPOSE:To make non-contact reading possible by storing parallel data beforehand in a P-ROM, and transmitting the data of P-ROM to outside when light energy is inputted to a solar battery. CONSTITUTION:An illumination is lit up and power source voltage is supplied from a solar battery to each block 1-5. Parallel data proper to a data source is inputted to a P-ROM 2 through a data input terminal 1. Then the data source is added to each article and sent to a beltconveyor in a tunnel. When the shifted article is illuminated by an illuminating lamp, the battery 8 supplies power source voltage to each block. When a clock generator circuit 4 supplies clock signal to a serial data generator circuit 3, the circuit 3 inputs parallel data from a ROM 3, and after converting the data to series data, outputs to an FM transmission circuit 5. The circuit 5 outputs the output signals of the generator 3 from an antenna 6 as FM modulated radio waves. On receiving the radio waves, the name, etc., of the article can be discriminated.

In FIGS. 1 to 3, reference numeral 1 denotes a data input terminal composed of a connector terminal, etc., and data is input in parallel to this data input terminal 1 via a path line of a personal computer or the like. 2 is a nonvolatile PROM that stores the input signal of the data input terminal 1; 3 is a serial data generation circuit that converts parallel signals from the PROM 2 into serial signals using a clock from a clock generation circuit 4; 5 is an FM transmitting circuit that FM modulates the output signal of the serial data generating circuit 3 and transmits it from the antenna 6. Reference numeral 7 denotes a power supply circuit composed of a solar cell 8 and a phototransistor 9, and this power supply circuit 7 supplies power supply voltage to each block 1 to 5 only when optical energy is applied.

Each of these blocks 1 to 7 can be easily stored in a card-shaped storage case using conventional card calculator, thin radio receiver, etc. technology. Also, to show an example of the performance of each block, the storage capacity of F ROM 2 is 16Kbit, and the oscillation frequency of the clock generation circuit is I

In FIGS. 1 to 3, first, the lighting 16 is turned on and power supply voltage is supplied from the power supply circuit 8 to each block 1 to 5. Parallel data unique to the data transmitting device 12 is then input from the personal computer to the FROM 2 via the data input terminal 1.

Thereafter, this data transmitting device 12 is transferred to each item 11.
and send it to the Peltoco/Bear 13 inside the tunnel 15. Since the inside of the tunnel 15 is dark, the phototransistor 9 is in an OFF state, and the power supply voltage is applied to each block 1 to 5.
I'L is not supplied to PROM 10, but only PROM 2 continues to store unique parallel data. Eventually, as shown in FIG. 3, when the moved item 11 is illuminated by the illumination lamp 16, the solar cell 8 generates a voltage and the phototransistor 9 turns O.
It becomes N (conductive) state and supplies power supply voltage to each block 1 to 5.10.
