Description

Detailed Description of the Invention 3. Detailed Description of the Invention (Field of Industrial Application) This invention relates to an apparatus using an information storage medium (optical memory) consisting of a row of minute dark and light areas.

<Background of the Invention> Recently, in the United States, a system was developed for recording data in the form of printed matter at high density and for reading the records. This system is called an optical memory system (note: in the United States, it is trademarked "5of5trip"). In this system, the length is 1501m,
A maximum of about 4KB of data can be recorded on a paper sheet with a width of about 15mm. The record consists of a collection of dark and light areas. In other words, several bits to several tens of bits are recorded in a series of minute dark and light areas (recording lines) in the width direction (perpendicular to the longitudinal direction) of a strip-shaped optical memory, and this recording line is then extended in the longitudinal direction of the strip. A large amount of data can be compressed and recorded continuously.

The difference from conventional barcodes, which record data as a set of consecutive dark and light areas, is that barcodes are 1-bit (
In contrast, in this optical memory, a combination of light areas and light areas that display a single digit (one digit) is consecutive to form one barcode, whereas in this optical memory, a combination of light areas and light areas that display a single line of recording lines is continuous. At 8
The point is that bits or 4 bits are expressed together. As a result, the size of each of the light and light areas can be reduced, so that the recording density can be significantly improved.

FIG. 5 shows a partial configuration diagram of the optical memory.

A header 10 is formed at the beginning of the data, and this header 10 specifies the number of bytes recorded in each recording line, the width of the recording line, etc. Further, the reading device is designed to judge the contrast between the light and light parts when reading this part. The thick line formed on the left side of the optical memory is the start line 12, and the thick line formed on the right side is the end line 13. Starting line 12. The end line 13 specifies the reading area by the reading device.

11 shows one recording line. An area having the illustrated width from the start line 12 to the end line 13 is an area occupied by one recording line. Since each recording line is recorded in close contact with each other in the band direction (longitudinal direction of the optical memory), in order to identify each recording line, a check section alternately records dark and light areas for each adjacent recording line. 14,132 are provided. The area from the check section 14 to the end line 13 is the data recording area of each recording line.

Although not shown, a mark for setting the reading device is printed at a specific position outside the optical memory.

FIG. 6 shows a usage state diagram of the reader for reading this optical memory. This reader is placed on the optical memory 1 or 1'. The mounting position of the reader can be determined by aligning the predetermined position of the reader with the symbols 17, 18, 17', and 18' printed on the side of the optical memory. FIG. 7 is a partial structural diagram of the reader. The reader consists of a reader case 20 and a reader section 21 provided inside the reader case 20. The league section 21 includes a transport system 22. which moves the league section 21 in the band direction of the optical memory. It is comprised of an optical system 23 that reads the shading pattern of the optical memory and an electric system 24 that converts the shading pattern read by the optical system 23 into a data signal and outputs it.

FIG. 8 is a configuration diagram of the optical system 23. This optical system 2
Reference numeral 30.3 consists of a light source section that irradiates light onto the optical memory and a sensor section that detects the reflected light of this light. It consists of a guide 31 that irradiates light from a light source onto a predetermined recording line of the optical memory. A condensing lens 32 is provided at the tip of the guide 31 to concentrate the reflected light from the recording line to approximately one point. A thousand cylindrical lens case 33 having eight lenses 34a to 34h of different phases on the circumference of the side surface is installed above the condenser lens 32.

This lens case 33 is rotatable by a motor 36, and as it rotates, the lenses 34a--
34h alternate in turn and face the condenser lens 32. A photosensor 35 (not shown) is provided to protrude from the electrical system 24 toward the inside of the lens case 33, and the light is collected by the condensing lens 32.
The amount of reflected light from the recording line selectively transmitted by any of the lenses 34a to 34h is detected.

FIG. 9 is a schematic structural diagram of the conveyance system. Said motor 3
6 rotates the lens case 33 and is decelerated by a gear 4o provided on the same axis and a gear 41 that meshes with this gear 40, and a worm 42 that is coaxial with the gear 41 and a gear 43 that meshes with this worm 42 rotates the leader. Part 21
Drive wheels 44 that move the whole thing. Since the rotation of the lens case 33 and the rotation of the wheels 44 are performed by the same motor 36 and the same conveyance system, the rotation angle of the lens case 33 (i.e., the rotation angle of the lens 34 facing the condensing lens)
The relationship between the alternation of a to 34h) and the moving distance of the optical system is constant.

FIG. 10 is a block diagram showing the configuration of the electrical system.

The sensor 35 is connected to an amplifier 46 to amplify the output value. The amplified output value is input to the determiner 47.

This determiner 47 reads data of 8 bits or a predetermined number of bits from the contents recorded on a single recording line. The read data is input to the R3-232-C interface 48, which interface 4

As mentioned above, the leagues currently in practical use require troublesome positioning during reading, and if this positioning is inaccurate, the data may not be read or the read data may be incorrect. Ta. Furthermore, this reading device is a self-propelled reader and has the disadvantage that it can only read optical memory within the travelable length of the optical system.
