The viewing screen is interchangeable with
Protractor or Photographing Screen, both
available on order. Onto the metal frame

of the screen, not only the chart clips but
the reading scale, available on order, can

be attached.

§ 1.

1. Viewing screen

FUNCTION OF EACH PART

(Fig. 4)

Fig. 4

The screen is fastened to the instrument
with the lock on the top and is released

by turning the lock counterclockwise (Fig.
5a) to the position as shown in Fig. 5b.

The chart clips serve to firmly hold a sheet of paper or plastic to be used as a master
chart on the screen.

Pull the clip head, and the clip will be released and can be turned.
It is detached from the screen by unscrewing its milled part.

4. Hood

(Fig. 4)

In case extraneous light obstracts the observation of the screen image, pull the hood
forward. The hood can be pushed backward when not in use.

Three projection lenses, mounted on the turret,

are changed over one after another by turning
the turret. Rotate the turret holding two of
the three knobs with both hands so that the

lens to be used faces toward the user, where

it click-stops exactly in the optical axis.

6. Projection lenses (Fig. 7)

(Available on order')

To screw in or out the lens from the turret,
hold its milled part.
To exchange the lens, do not forget to lower
the stage beforehand.
The projection lens with a built-in half-reflecting
mirror has the lower end rotating around the
optical axis, so that the mirror can be faced
toward the surface illuminator.

Fig. 7

7. Anti.glare shield

(Fig. 2)

The shield can be swung freely around the vertical and horizontal axis.
It serves for preventing glare caused by scattering light from the surface of specimen.
The shield can be detached from the instrument by rotating the black knurled part.

8. Stage mount

(Fig. 8)

Release beforehand the knurled screw on the right-hand bottom of the stage to be

mounted.
Place the stage over the central protrusion on the mount.

Fasten the stage to the mount by means of the knurled screw.
The micrometer stage should be fastened in such a position that the crosswise travelling

directions coincide with the cross lines engraved on the screen.
Be careful enough in handling the stage to keep its high accuracy.

As to the specifications of the stages, refer to the tables on p. 20.

9. Change·over knob for contour illumination

(Fig. 8)

Releasing the milled knob by turning counter-

clockwise, move it downward, and the conver-
gence of illuminating light will be changed
continuously. For projection 100x or higher,

fasten the knob in the position 100 x .

Fig. 8

10. Contour illuminator (Fig. 9)

To take out the lamp house, slightly release
the fastening sCrew, turning clockwise (viewed

from above) the knurled part, pull out the lamp
house downward.

For replacement, insert the lamp house with

the top end of the groove faced toward the

side opposite to the fastening screw. Push in
the house by turning counterclockwise. Lock
it in position with the fastening screw.

Three screws are provided for centering the

lamp. These screws being released, the lamp

can be rotated by turning the base of the

lamp socket.

11. Surface illuminator (Fig. 10)

After the knurled screw at the right is released,
the condenser can be drawn in and out to

change the convergence of illuminating light.
To take out the lamp, release the lamp and

the screw at the left.
The three screws around the lamp socket are
used for centering the lamp.

Release these screws, and the lamp can be

rotated by turning the base of the lamp socket.
To set the surface illuminator in proper posi-
tion, move the surface illuminator vertically
along the supporting rod after the lock screw

is released. It can also be tilted for itself.
Lubricate the fan motor at its bearings with

machine oil once or twice a month.

12. Surface illuminator support (Fig. 10)

Fig. 9

Fig. 10

Release the black knurled grip at the bottom of the supporting rod by turning counter-
clockwise. Then, the supporting rod can be swung laterally.
Lock it in the desired position by fastening the grip.

13. Focusing wheel

(Fig. 14)

Turning of the wheel moves the stage vertically in a range of about 180mm.
One rotation of the wheel moves the stage about 2 mm.
The wheel is provided with a device which stops the movement of the stage when this
comes to the top and bottom limit. Beyond these limits the wheel cannot be turned.
Operate the wheel gently at the neighborhood of these limits.

(After the instrument is installed, the removal of the red·colored bolts (Fig. 29) is
necessary.)

14. Cabinet (Fig. 11)

(Available on order)

The accessory cabinet can be attached to
either side of the instrument by means of 4

bolts supplied with the instrument. Move the
inside shelves to the bottom, and the lens case
can be stored in the cabinet.

16. Fuse (Fig. 12)

To replace the fuse, take out the fuse cover
by turning in the direction of the arrow.

The socket accepts the power cord plug.
Fasten it with the nut outside of the plug.

The sockets for illuminators and for the cooling

fans are manipulated likewise.
