immediately, and remove the camera cable from the camera connector. In such case,
contact us or our dealer/distributor from which you purchased the camera for repair
service.
If any foreign object / liquid gets into the camera, discontinue the use immediately.
In the event that liquids, small particles, or any other foreign objects get into the camera,
do NOT try to continue to use the camera. To do so invites a fire or an electric shock
hazard. In that case, turn the power switch of the camera OFF immediately, and remove
the camera cable from the camera connector. After that, contact us or our
dealer/distributor from which you purchased the camera for repair service/technical
advice.
Do NOT disassemble the camera
Do NOT attempt to pull apart, repair, or modify the camera on your own. To do so leads
to a fire or an electric shock accident. Contact us or the dealer/distributor from which
you purchased the camera for repair/modification.
Do NOT supply any power other than specified.
The camera is designed to work only under specified voltage. Do NOT attempt to drive
the camera with the power other than specified. Operating the camera under unspecified
power invites a fire or an electric shock hazard.
Do NOT use the camera in a high-humidity environment.
Do NOT place the camera near a humidifier, or in other high-humidity environment.
To do so may cause a fire or an electric shock accident.
CAUTION
If the camera is operated in the electromagnetic field, there may be cases where beat
noises (vertical, horizontal, or oblique stripes) may appear in the video output. In that
case, take preventive measures on the electromagnetic-wave generating source so that
the camera do not receive the interference by the electromagnetic-wave. Take extra
precautions against electromagnetic-wave-interference if the camera is used with a
servomotor, inverter, or other electromagnetic-wave-generating equipment.
Avoid giving a strong shock against the camera. If your camera is used in the system
where its camera connector is subjected to strong repetitive shocks, the camera
connector is possible to break down. If you intend to use your camera in such a situation,
make sure to use an optional camera-connector-fixing-hardware to connect the
connector-plug to the camera body.
When the camera is not in use, make sure that a lens or lens-cap is put on so that the
image pickup plane of CCD is protected from dust, foreign object, or other flaw-causing
object. If the glass plane (image pickup plane) gets dirty, clean it with a cotton swab.
When it needs to be cleaned with a cleaner, be sure NOT to use any organic solvent other
than ethyl alcohol. As a countermeasure against condensation, when the camera is
moved from a warm place to a cold place, take appropriate precautions to prevent
condensation from forming on the camera.
Do not pull strongly the camera cable nor swing it. The stress from pulling or swinging
may cause damage in the coating of the cable, or breaks in the inside wires.
2
Avoid shoat-circuiting its signal output. Otherwise, the camera might be damaged.
If too much amount of light, (= the incoming light amount of 100 times or greater in
comparison with standard light) enters CCD image pickup plane, video output might not
be obtained. In such a case, take measures to reduce the amount of incoming light.
Do NOT expose the camera to intensive light (sunlight, etc.) to prevent its inner CCD
from getting damaged.
When mounting a lens, take extra caution so that the lens is not tilted, nor does flaw exist
at the lens-mount-screw part. Also check to confirm that no dirt nor other foreign object
is put inside. Improper mounting might cause the parts to become locked.
Do NOT connect/disconnect connectors with power ON.
Before connecting/disconnecting connectors, make sure to check if the system. is
powered OFF. Doing so with power ON may cause a damage or an electric shock
accident.
DANGER
Do NOT use any optional unit other than manufacturer-supplied one. [We disclaim any
[ responsibility for damages or losses incurred by user due to the use of unauthorized /
unofficial option units supplied by a third-party]

1. PRODUCT DESCRIPTION
Model CS3720 is a separated-type (two-body) B/W CCD camera with all-pixel-data
readout CCD. This model has twice greater driving frequency of CS3710 to achieve
fast-speed data-processing. The model is suited for high-speed, high-resolution image
processing use.
2. FEATURES
(1) Double-speed scan
This model reads out image-data twice as fast as conventional cameras do.
(2) All pixel’s data readout
With its built-in all-pixel-data-readout CCD, this model can read out image-data just in
approximately 1/120 sec. A frame-shutter reads out all data even under RTS mode.
(3) Random trigger shutter function
With a built-in RTS (Random Trigger Shutter), the camera’s CCD starts light-exposure
in synchronization with external trigger signals. This function enables the camera to
capture fast-moving subjects at constant position for precise image processing.
(4) Programmable partial scan
Readout portion of pixels is determined by external pulse. As only needed portion is
read out, further speed-up in data-readout & processing is achieved.
(5) High vertical resolution
As all pixel’s data are read out even under RTS mode (in 1/120 sec.), images with no
deterioration in vertical resolution are obtained.
(6) Square grid pattern CCD
Pixel’s in CCD ace aligned in square grid pattern. This makes it easier to perform
computation correctly for image processing use.
(7) External Sync.
The camera is switched over to external synchronization operation automatically when
external HD/VD signal is input.
(8) Multiple shutter
With this function, the camera can capture video at any given timing, then outputs
video images at a set timing.
(9) Ultra-compact & light-weight camera head
The model features its ultra-compact and light-weight camera head, freeing you from
your integration-space-problem. In addition, it has an excellent shock & vibration
resistance.
