Ultra-Compact Digital Barcode Reader

[Converts to easily decodable information]

Controls the waveform of the received beam to set its amplitude to a level suitable for reading.




[Accurately detects the points of alternation between bars and spaces]
Acquires the received beam waveform in 10-bit gradations and applies differentiation (shown in waveform diagram on left).

Removes the noise components—signals not relevant to the code information such as faint printing and background patterns.

Detects the points of alternation between bars and spaces (edges).




[Modifies the narrow/wide ratio to enable accurate decoding]
Identifies bars and spaces from extracted edges. RPM! adjusts the narrow/ wide ratio to eliminate the negative impact of running print ink and reader mounting angle.

Thick print lines

Problem: Spaces are extremely narrow

Previous Models

Thick print lines prevented adequate space between bars, forcing the reader to move to the next bar without obtaining the proper amplitude.

BL-1300 Series

3Hi-Digital models use noise reduction and edge detection to recognise the difference between spaces and faint printing, enabling accurate decoding.

Reading from diagonal orientation (pitch angle)

Problem: Drop in received beam intensity, bar ratio variations

Previous Models

When reading from an angle, previous models couldn't receive adequate beam intensity, and barcode recognition failed.

BL-1300 Series

3Hi-Digital models reliably detect edges to recognise barcodes, and use RPM! to compensate for bar width ratio variations created by tilted orientations.
