II. D E SCRIPTIONS FOR FILM ADVANCING/SHUTTER
CHARGING AND RELEASING MECHANISM
1. When the camera is loaded with a film and camera back is closed, the return lever (4-39) is
pushed by the back cover, causing the rotary plate assembly (4-77) to turn. Then, the gear (4-79)
engages with the gear assembly (4-78). At this time, the head A of the lever assembly (4-88) is
slightly separated from the disc (4-99). Therefore, the pawl (4-36) disengages with the pawl
wheel (4-20) allowing the film advance lever to be wound up.
At the same time, the lock lever assembly (4-51) and lock lever assembly (2-26) turn, causing the
lock pin (2-25) to enter the space under the release lever (7-99), prohibiting the shutter releasing.
NOTE:
When these two lock levers (4-51 and 2-26) do no operate correctly (due to unhooked
spring, existence of dust, etc.), the shutter is not locked, allowing the shutter to be released
before the film is taken up one frame completely.
2. When the film advance lever is wound up, the gear (4-9) which turns simultaneously with the
sleeve assembly (4-6) causes the disc assembly (4-12) to turn through the pawl (4-18), and the
energy is transfered to the gear (4-22) and gear assembly (4-32) causing the film to be advanced.
At the same time, as the gear (4-42) turns, the rack assembly (4-47) is pulled up by the shaft
(4-71) of the ratchet wheel assembly (4-66) at the first wind up, the gear (7-119) is turned by the
teeth of the rack, and with the gear of set plate (7-42), the shutter is charged through the gear
(7-54). [Arrow ©in Fig. Ill]
Then, the hook^of the rack assembly (4-47) hooks on the hook (4-72), and its head enters the
space beneath the release lever.
At the same time, the lever assemly (4-114) which has been hooked on the ratchet is kicked by
the last projection of the ratchet, the lever assembly (4-55) enters the hook, the pawl disengages
with the ratchet, the interlock pin (4-57) moves away from the lever assembly (4-88), the head @
of the lever assembly (4-88) rides on the disc (4-99), the head@of the lever assembly (4-88)
further drops into the recess, and thus, the shutter is allowed to be released.

3. When the film is wound up further continuously, the exposure counter drum assembly (2-3)
which is turned by friction of the film and take-up gear (2-19) turn, causing the gear assembly
(4-60), gear (4-76) and gear (4-78) to turn. Thus, the exposure counter advances from “S” to
“1”, the head @of the lever assembly (4-88) drops into the recess on the disc (4-99), the pawl
(4-36) which is interlocked with the lever assembly engages with the pawl wheel (4-20), and thus,
the winding up stops.
At the same time, the lock lever assembly (4-51) pushed by the head@of the lever assembly
(4-88) causes the lock lever assembly (2-24) to turn. Then the lock pin (2-25) moves away from
the release lever, allowing the shutter to be released.

4. When the shutter release is depressed with the lock lever (1-29) so set that the red mark can be
seen (unlocked), the release lever assembly (7-98) is pushed by the shutter release shaft (1-20),
it further pushes the head of the rack (4-47) down, and thus, it is unhooked with the hook
(4-72).
The rack (4-47) pulled by the spring (1-22) moves rapidly, and causing the gear (7-119) to tum
reversely, the rack kicks the lever assembly (4-55), unhooking the lever assembly (4-114). The
rack further moves rapidly, turns the gear (7-54) causing the set plate (7-42) to tum, and thus,
the shutter is released.
5. As soon as the shutter is released, the lever (7-102) pushes the pawl (4-36), the pawl (4-36) moves
away from the ratchet, and the head A of the lever assembly (4-88) is pulled out from the recess
on the disc (4-99).
At the same time, the pin (4-57) on the lever assembly (4-55) kicked by the rack supports the
lever assembly (4-88).
Further, the lock levers (4-51 and 2-37) tum toward the locking direction, and when the shutter
release shaft returns as the shutter release is freed from the depression, the lock pin (2-25) enters
the space beneath the release lever, and thus, the shutter release is locked.
The lever assembly (4-114) is released, hooked on the ratchet wheel (4-66), and thus, the lever
assembly (4-114) functions to prevent reverse tum.
6. The lever assembly (4-114) functions to prevent reverse tum of the shutter charging mechanism
until the shutter is charged completely. Without this function, the shutter is not charged but the
film is advanced when the film advance lever is wound up gradually, and as the exposure counter
advances, the shutter is allowed to be released before it is charged completely in a middle
between frames, or the shutter cannot be released and the film is not wound up.
Note that the lever assembly (4-114) is important. If this lever assembly does not operate
smoothly, the camera does not operate correctly.

7. When all frames are exposed and the film reaches the end, the exposure counter drum assembly
(2-3) no longer turns. Then, the shutter is locked prohibiting the releasing.
When the camera back is opened, the return lever (4-39) returns, the rotary plate assembly (4-77)
turns, the counter gear (4-97) disengages with the gear assembly (4-78), the exposure counter
returns to “S", and the camera returns to the condition before loading a film.
8. The series of operations from film loading to the end of photographing through film advance¬
ment, exposure counter advancement, shutter charging and shutter releasing were described
above.
When repairing, disassembling and reassembling the camera, the series of operations must be fully
understood so that each function of the camera can be fully displayed.
