3.2.4 ASSEMBLY/DISASSEMBLY OF [19] OP BLOCK ASSEMBLY/CCD BOARD ASSEMBLY
z
Precautions
(1) Take care in handling the CCD IMAGE SENSOR, OPTI-
CAL LPF and lens components when performing mainte-
nance etc., especially with regard to surface contamination,
attached dust or scratching. If fingerprints are present on
the surface they should be wiped away using either a sili-
con paper, clean chamois or the cleaning cloth.
(2) The CCD IMAGE SENSOR may have been shipped with
a protective sheet attached to the transmitting glass.
When replacing the CCD IMAGE SENSOR, do not peel
off this sheet from the new part until immediately before
it is mounted in the OP BLOCK ASSEMBLY.
(3) The orientation of the OPTICAL LPF is an important factor
for installation. If there is some marking on the OPTICAL
LPF, be sure to note it down before removing and to reas-
semble it very carefully as it was referring to the marking.
z
Disassembly of OP BLOCK ASSEMBLY / CCD BOARD AS-
SEMBLY
(1) Remove the two screws (1,2) and remove the CCD
BASE ASSEMBLY and CCD BOARD ASSY.
NOTE19a:
When removing the CCD BASE ASSEMBLY, be careful
in handling as the CCD IMAGE SENSOR may be removed
together with the SHEET and the OPTICAL LPF attached.
(2) Unsolder the 14 soldered points (SD19a) on the CCD
BOARD ASSEMBLY, and then remove the CCD BASE
ASSEMBLY and the BRACKET.
NOTE19b:
Replace the CCD IMAGE SENSOR as a CCD BASE
ASSEMBLY, not as a single part replacement.
z
Assembly OF OP BLOCK ASSEMBLY / CCD BOARD AS-
SEMBLY
(1) Set the OPTICAL LPF first, and then the SHEET to the
OP BLOCK ASSEMBLY.
NOTE19c:
Be careful with the attachment direction of the OPTI-
CAL LPF.
(2) Set the CCD ASSEMBLY, BRACKET, and then CCD
BOARD ASSEMBLY in order so that the SHEET is not
displaced, and fasten with two screws (1, 2).
(3) Set the CCD BOARD ASSEMBLY to the CCD BASE AS-
SEMBLY, and then solder the 14 points (SD19a).
z
Replacement of service repair parts
The service repair parts for the OP BLOCK ASSEMBLY are as
listed below.
Take special care not to disconnect any of the FPC wires or
cause any damage due to soldering (excessive heating).
(1) FOCUS MOTOR UNIT
(2) ZOOM MOTOR UNIT
(3) AUTO IRIS UNIT
NOTE19d:
When replacing the FOCUS MOTOR UNIT or the ZOOM
MOTOR UNIT, solder the FPC at a space of about 0.5 mm
above the terminal pin.
NOTE 19e:
The AUTO IRIS UNIT includes the FPC ASSEMBLY and
two sensors.
