The Brief History of Takenaka System Co.
Takenaka System Co.(Trade mark:TAKEX) is the Japan’s first company to have produced the Line scan
cameras. It was established in 1975 and began to produce and sell the Line scan cameras that year.
And then, Takenaka System Co. is continuing to produce high quality line scan cameras such as C-MOS/
CCD Line scan cameras, CCD Analog line scan cameras, CCD Digital line scan cameras and CCD Camera
Link line scan cameras, as a pioneering company in the Japanese industry,.
Also, Takenaka System Co. began to produce the compact CCD video cameras since 1983, and is a first
producer of Full frame shutter cameras (Progressive scan camera) in Japan.
We think it is a mission of our company to continue to provide the high-quality Line scan cameras and Full
frame shutter cameras to the industry as image input device for image processing apparatus.
We are confident that the Takenaka’s products that met the strict delivery basis are assured of trouble-free
operation over a long period of time.

1. Outline
● CCD line scan camera with 7400 pixels of image sensor and of 100MHz data rate.
● TL-7400RCL adopts the video signal output format complying with Camera Link standard (Unified standard
for digital camera interface for industry).
● 4×8 /10 bit digital image signal output complying with Camera Link (Medium Configuration).
● Perfect line scanner for high-speed and high-resolution image processing device.
2. Features
● It matches well to most of capture boards from other manufacturers, which makes it possible to construct
high-precision image processing systems.
● GAIN can be changed from 50V/Lux.sec to 400V/Lux.sec in 8 steps.
(Analog output equivalent: it is set to 200 V/Lux . sec as a factory setting.)
● The sensitivity (GAIN) and 8/10 bit format can be easily changed with RS232C command from capture
board.
● The equipment operates with a single DC12V power source.
● Best suited usage for different purposes is feasible as GAIN can be set at one,two,three and eight-fold
sensitivity.
● The 4.7µm×4.7µm pixel size sensor enables High-definition image acquisition.
● CCD line sensor with four output ports.(4×25MHz)
● Compact and low price.
3. Applications
● Image processing device for Image inspection.
● Measuring device such as appearance inspection or dimensional measurement device.
● Surface inspection apparatus of sheet-like object.
● High-resolution pattern inspection instrument.

4. CCD image sensor
The
CCD image sensor Is characterized by 4.7 μm square pixel, 7400 effective pixels and high speed performance.
Charges accumulated in single-row photo diodes are divided into four groups (No.1 for ODD numbers of first
half , No.2 for EVEN numbers of first half, No. 3 for ODD numbers of latter half ,No.4 for EVEN numbers of
latter half ) and are output thorough 4 shift registers, respectively.
Each shift register operates at 25MHz data rate.

6. Camera I / O
6-1 Power connector
Power is supplied through 6 pin connector.
Though ripple-free and stable power source is preferable, the switching supply is also employable. In general, ripple
voltage of a stabilized power source is approx.35mV, and approx.120mV for a switching supply. As voltage ripple is
added to video signals, S/N ratio degrades when ripple voltage is too large.
When two or more line scanners are connected to a single power source, be sure to keep cables from varying
extremely in length from others. When cable length varies greatly depending installation location of line scanner and
power source, dispersively install multiple small-capacity power sources.

7. How to change settings
The ODD/EVEN video signal gain and the camera gain are changeable as needed by removing the camera
cover,.
7-1 Fine adjustment of ODD/EVEN video signal gain
Gain adjustment of ODD/EVEN video signal is not normally needed, as it has been set before shipment.
However, when it is needed, make a fine adjustment following the diagram below.
7-2 How to change camera GAIN
The camera gain has been set to “×4” as a factory default.
It is able to double the gain using the built-in GAIN switch.
Select “×1” when high-quality image is needed, and select “×8” when high sensitivity is needed even if image
quality degrades. Select “×2 to ×6” depending on the degree.
