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 devices for image processing apparatus.
We are confident that the Takenaka’s products that met the strict delivery criteria are assured of trouble-free
operation over a long period of time.

4. CCD image sensor
The CCD image sensor Is characterized by 4.7μmsquare 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 four shift registers, respectively.
Each shift register operates at the rate of 25MHz.

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 more than one line scanner is connected to a single power source, be sure to keep cables from varying
extremely in length. When cable length varies greatly depending installation location of line scanner and power
source, use 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.
