(CI. 88-15)
My present invention‘ relates to a camera and
more particularly to a folding camera. -
One of its objects is to provide a folding camera
in which the brilliant finder‘ is arranged- in an
‘l improved manner. Further objects will be seen
from the detailed ‘speci?cation following here
after. Reference is made to the accompanying
drawings in which

10" ing camera having theybrilliant ?nder‘ mounted

Fig. 3 is a lateral View of the camera shown
in Fig. 2 in closed condition.
Hitherto the ~brilliant finder is generally ro-j
tatably mountedon the lens front of a camera
26
and so that‘ it‘ can be folded thereon. When
mounting the brilliant ?nder in ‘this manner it
may be‘ di?icult‘ to fold the baseboard‘ on the
camera body, because in the case of the brilliant
?nder being but slightly turned out of its normal
position, the camera cannot be closedythe cable
25" release placed round “the” ?nder may increase‘
the ‘troubles. ‘ When'closin'g the camera by force‘
itmay easily occur that the ‘means holding the
?nder‘ is deformed, so that the picture section‘.
viewed through the ?ndercorresponds no longer
30"“ to that focussed by the ‘camera. In addition, on
a diameter greater than the widthlof the camera.
The ?nder lens facing the eye is tiltable in ‘such
a manner that it lies parallel to the ?nder mirror
when the camera is closed, whereas it lies out
side the camera casing when in the proper posi
tion for focussing.
In the camera represented in Fig. 1, the bril
liant ?nder 3 is mounted inside the folding
camera 2 above the spool chamber l. The bril
liant ?nder, as is known, consists of the ?nder
lens 4‘ facing the object to be taken, of the ?nder
mirror .5 and‘of the lens 6 facing the eye of the
operator. According to the invention the di
ameter of the lens 6 is chosen as large as possible,
in order that the object to be taken can be
viewed in full detail. Above the ?nder lens 6
there are ‘arranged two light shades l and 8
which preferably are unfolded together with the
15'
camera and which, when the camera is not used
form part‘of the camera casing.
‘ In the example of apparatus represented in
Figs. 2 and 3, the ?nder lens is larger than is
the Width of the camera, in order to obtain the
picture viewed through the ?nder in approxi
mately the same size as has the picture focussed
on the light sensitive material.“ In order that
lens 6 may be folded into the camera casing,
it is attached to the casing by means of a pair
of pivotally mounted levers l, which by a spring
urged hinge 8 guide automatically lens 6 con
account of the limited space available, ‘the ?eld‘ nected with the levers by means of a pin and

order to overcome

‘ these

\
accord
3:51 be
ing to the present invention ‘the brilliant ?nder‘
is mounted' inside the “casing of the folding
camera. When mounting the brilliant ?nder in
this way, the part of the camera casing lying on
40 top of said ?nder may form in the operative posi
tion of the ?nder an observing hood, whereby the
detrimental lateral incidence of light can be
avoided. Another advantage resides in the fact
that the operator must not bow so much on the
45 camera when taking a picture since the opening
for viewing the ?nder lies immediately below the
eye when the camera is hung round.
With a brilliant ?nder according to this in
vention the ?nder lens which is nearest the eye
50 may be given such dimensions that its picture
?eld has the size of at least one third of the
picture section focussed on the light sensitive
material. By mounting the ?nder lens facing
the eye so that it is out of the camera casing in
55 its operative position, the ?nder lens may have
of the hinge 8 the lens is constantly pressed‘
against the stops 9 and 10 provided on the light
shades H and I2. For folding the ?nder lens"
6, it must be pushed at the point indicated by
the arrow A and at the same time the light shade
II must be folded. In doing this, the lens at
?rst merely turns about its pivoting point (cf. 40
arrow B) and then slides in the direction of
the mirror plane until it comes to lie approxi
mately parallel to the mirror. Then the light
shades are folded in the order of numbers [3,
l4, l2. The light shade l2 which is folded last 45
is preferably so constructed that the camera
casing, after closing the observing hood assumes
an approximately symmetrical form and the hood
is retained in its closed condition by a snapping
device, not represented. All of the light shades 50
are under the in?uence of springs 15, so that,
when the arresting means is released they auto
matically spring open. In the light shade ll
there is provided a slot l6 which co-operates
with a pin l1 ?tted on the lens mount 6a, so 55

that the ?nder lens 6 can give way in folding
it and flap l2 likewise can be folded.
