4. Attachment and Removal of Film Backs (con’t)
A. To attach the film back to the main body, simply insert the latches
at the upper end of the film back into the attachment openings at
the upper end of the main body. Then, press the lower end of the
film back against the main body until it locks securely.
* The dark slide must be withdrawn from its slit, upon attachment of
the film back to the main body, as otherwise the shutter cannot be
released.
B. The dark slide must be inserted into the dark slide slit in order to
remove the film back from the main body. Insert, with the mark at
the top, as illustrated, and then push in all the way.
* There is danger of the film back becoming detached from the main
body, if the dark slide is left in its slit while the camera is being car-
ried. Therefore, make it a rule to withdraw the dark slide whenever
the film back is attached to the main body.
C. Depress the film back release button and the lower end of the film
back can be removed, as illustrated. Simply shift the film back up
slightly and pull it away.
* The dark slide cannot be withdrawn from the film back when the
film back is detached from the main body.
5. Construction of Film Back
A. The film back consists of a film holder and film back frame, with
exclusive film backs available for 120 and 220 roll films. The film hold-
er is not only detachable from the film back but also has a built-in
film winding mechanism.
* Read instructions supplied with the Film Back GS 135 for loading
135 roll film.
