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.

12. Notes
Precautions for use
■Do not make an impact on the equipment.
■Do not lag the equipment with heat insulating agent. If the equipment is covered with heat insulating agent, It
produces an increase in teｍperature and it causes the equipment to malfunction.(except for low-temperature
environment use)
■Take appropriate measures such as heat removal or cold removal to prevent dew condensation, when the
equipment is moved to the place where temperature difference is extremely severe. Usage with dew
condensation causes the equipment to malfunction.
■When the equipment is not used for a long time, protect the imaging device from dust or scratch by attaching a
lens cap. Do not store the equipment at the following places.
・The place where is subjected to a lot of dust and moisture.
・The place where is subjected to direct sunlight.
・The place where is extremely hot or cold.
・The place in the vicinity of an object which generates intensive electromagnetic field.
・The place where is subjected to intensive vibration.
■Please wipe off the dirt on the lens surface with a cotton swab preventing scratch to the lens surface.
Use a soft cloth to clean up the camera body.
■Use the equipment with a voltage within the range of specifications and do not connect the equipment to a power
source that contains intense noise components. In such case, the image output from the camera may contains
noise components.
■Do not use the equipment in an environment subject to intense electromagnetic field.
In such an environment, malfunction of the camera, disturbance of image and noise are caused by the field.
■In case of the high-intensity object, it may happen that even the low intensity part is displayed whitely like a
vertical streak above and below the high-intensity object. This phenomenon is called “smear”. However it is the
problem specific to CCD and it is not the camera-related failure.
■In case of the linear object, jagged picture may be displayed. Also in case of the pinstripe or checkered pattern,
annual rings- like picture may be displayed. However these are also the problem specific to CCD and it is not the
camera-related failure.
■The lighting using a commercial power source may cause a perceptible flicker at higher shutter speed.
In cases like this, consider to adjust shutter speed setting of the camera or to use the DC lighting or high-
frequency lighting.
Attention
■All rights on this manual reserved.
■The specifications and operational details described in the manual are subject to change for performance
improvement or other reasons without notice.
