Scanning performance

Two models available for a wide range of applications

[QB30] Wide-eld model with small footprint

[QB30] Wide-eld model with small footprint

With its compact body and wide-angle lens, QB30 can be installed in a small space without needing to be a certain distance from the scanned object. It can reduce installation space when mounted on a kiosk terminal, allowing users to install it anywhere they wish.(1)

[QB31] Standard-range model allows scanning from a
distant position

[QB31] Standard-range model allows scanning from a distant position

With its deeper scanning eld, QB31 can scan objects distant from it.
It is perfect for plant production lines, thereby contributing to improved site productivity.

Batch scanning of multiple codes

It can shorten the scanning time through batch scanning up to 8 codes within the scanning range.(2)

Supports multiple codes

Batch scanning of multiple codes

In addition to the conventional barcodes and 2D codes, QB30 supports latest 2D code such as iQR and Aztec code.

Application Example

Where can QB30 be useful?

Manufacturing : Production line

Manufacturing : Production line

It can shorten the scanning time through batch scanning.

Distribution : Multimedia terminal

Distribution : Multimedia terminal

Built-in space can be reduced with wide scanning area.

Amusement : Entrance gate

Amusement : Entrance gate

High speed scanning achieve a smooth admission procedure at the entrance gate.

Features of main unit

White LED which can cope with all codes

White LED which can cope with all codes

White LED is adopted as the lighting LED, allowing it to read color codes. It minimized glare by using a milk-white material at the lighting unit.

Superior usability

Configuration software

setteing 1

Setting 1

Using COM port communication, Parameters are set in a batch.

setting 2

Setting 2

QR codes for batch setting can be printed out using configuration software.
Parameters can be set easily when scanning the QR codes.

Command Control

Command Control

Various parameters can be configured through communication command.
Therfore, according to the status of use, the settings can be changed from higher rank units.

Parameters can be controlled from PC.
  • Scanning ON/OFF
  • Scanning codes
  • shutter timing
  • Gain switching
  • Lighting LED controlling, etc.

Buzzer, LED, Magic Key

uzzer, LED, Magic Key

Equipped with a buzzer and LED to notify scanning completion or scanning error. The status of the scanner can be checked by it. Moreover, "scanning ON/OFF" can be controlled with magic key.

  • Power LED : Orange color
  • Scanning confirmation LED : Three colors LED (blue, green, red)
  • Magic key : Switching among "Scanning ON/OFF" and "USB keybord I/F" and "USB-COM I/F"(1)
  1. I/F switching is available only for USB model.

Data edit

Data edit

Corresponds to simplified programming language "ADF script". You can editt the data freely and the load on the host device can be reduced.

Data edit

Data collation

Data collation

By the registration of the master data, collation with the scanned data is available.

Collation modeDescription
1.Scanning input mode After receibing the "master resistration command" from the host device, the first scanned data is resistered as a master data for collation.
2.File input mode Collation with the resistered master data which is transmitted from the host device to QB30 in advance. ( The number of master data is up to 50. )

QB30-SR(RS-232C model)

I/O model (QB30-SR)

QB30 has I/O function. Through a mini Dsub-15 pin connector, it can be controlled from the host device. When supplied with +5 V power from the host device directly to the pins, Outlet for AC adapter is not required.

Example:Production line and Specimen device

Example:Production line and Specimen device

Trigger signal is transmitted to QB30 with precise timing. The codes on specimens are scanned according to the signals. When a read error occures, NG signal, that controls the patlite, is transmitted from the output terminal.

  1. Please don't connect to pin 1, 7, 12.
  2. Isolated from the ground of QB30.
