     FIELD OF THE INVENTION 
     The invention relates to techniques and equipment for assembling products such as cameras and more particularly relates to a method for assembling a critically positioned camera component on a camera body. 
     BACKGROUND OF THE INVENTION 
     U.S. Pat. No. 5,472,543 entitled “Method for Label Application Using Bernoulli Effect”, which is hereby incorporated herein by reference, discloses a labeling method in which a label is floated on an air cushion into a substantially exact alignment with an area of an item receiving the label. It has been determined that this method is very efficient and the precision of label placement provided by this method is very great. 
     Cameras conventionally use a large number of components that are individual pieces which must be separately assembled with the rest of the camera. Precise positioning of these components is generally a function of other support structures. 
     It would thus be desirable to provide an improved assembly method in which a component is preassembled with a support sheet, such as a label, and is then precisely positioned on a body. 
     SUMMARY OF THE INVENTION 
     The invention is defined by the claims. The invention, in its broader aspects, provides a method for assembling, in which a component is critically positioned on a larger body, such as a camera. The component is joined to a predetermined attachment area of a support sheet. The support sheet is floated into alignment with a labeler head. The labeler head is positioned in alignment with a predetermined location on the body. The body is contacted with the support sheet and the component while maintaining the alignments. A camera can be maintained light-tight during the joining, floating, positioning, and contacting steps. 
     It is an advantageous effect of at least some of the embodiments of the invention that an improved assembly method is provided, in which a component is preassembled with a support sheet, such as a label, and is then precisely positioned on a body.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring initially to FIGS. 1-19, in a component positioning method, a support sheet is used, with a Bernoulli effect labeler head, to accurately position a component on a workpiece. As a matter of convenience, the assembly method is generally discussed herein in terms of a preferred embodiment in which the workpiece is a one-time use camera. It will be understood that the method is applicable to other types of workpieces and is not limited to cameras of a particular type, nor to cameras in general. 
     The camera  11  has the component  16  installed in operative alignment with a camera subsystem  100  (indicated by a dashed line in FIG.  1 . (Subsystems and aligned components are discussed in detail below.) The support sheet  14  can be retained on the camera body  18  as a label. The label can bear indicia and other printed matter on the front or rear side  17 , 19  of the component-bearing-label  128  or both; and can be transparent or have a transparent region (not illustrated). In some cases, all or part of the camera body  18  or component  16  may be transparent to allow visualization of the rear side  17  of a label. 
     The support sheet  14  can be a temporary carrier  14   b  for the component  16 . In that case, the carrier  14   b  is removed after the component is attached to the body  18  (prior to use of the camera  11 ). Alternatively, after assembly, the component  16  can be held on the body  18  by all or part of the support sheet  14  or can be held by the body  18 , or can be held by both. The component  16  and label  14  can together be what is referred to herein as an “component-bearing-label  128 ”. In that case, the component  16  is inseparable from at least part of the support sheet  14 . The component  16  can be made in one-piece with the support sheet  14  or can be separate until assembly. 
     The support sheet  14  is thin and, preferably, flexible. The support sheet  14  has a rear side  17  which is adhered to the body  18  or component  16  or both and a front side  19  that is opposite the rear side  17 . For convenience, support sheets  14  are generally discussed herein in terms of labels  14   a  having printed matter only on the side of the component-bearing-label  128  that is not adhered to the camera body  18 . It will be understood that like considerations apply to other types of support sheets  14 . 
     Detailed features of components  16  and subsystems  100  can vary. Different electrical and optical components and related subsystems are described below. A single camera  11  can include multiple subsystems  100 . The same support sheet  14  can be shared by more than one subsystem  100  or individual support sheets  14  can be used with individual subsystems  100 . For convenience, the camera  11  is generally discussed herein in terms of one or more components  16  positioned by a single support sheet  14 . The component  16  can be manufactured as a part of an component-bearing-label  128  or can be joined to an component-bearing-label  128  (or temporarily joined to a carrier) during camera assembly. FIGS. 1 is directed to an assembly method in which a separate component is joined to a label. FIG. 2 is directed to an assembly method using a carrier  14   b.  FIGS. 3-19 are directed to Bernoulli labelling equipment and methods generally. 
     Referring initially to FIG. 1, an component-bearing-label  128  is supplied ( 102 ) to a labeler head  48  and retained ( 104 ) in a predetermined position on the labeler head  48 . (Suitable Bernoulli labeler heads, apparatus, and procedures are described in greater detail below.) The component  16  is then provided ( 106 ) in a predetermined location, in a nest or other support  15 . The labeler head  48  is and retained component-bearing-label  128  is then positioned ( 108 ) relative to the nest  15  and component  16  and the component-bearing-label  128  is driven ( 110 ) against the component  16 . The component  16  adheres to the component-bearing-label  128  (preferably on contact) and is thus, retained ( 112 ) on the component-bearing-label  128 . 
     The component  16  is light weight and small relative to the component-bearing-label  128 . The adherence of the component  16  to the component-bearing-label  128  can be provided by an adhesive coating on the back of the support sheet  14 . Adherence between the support sheet  14  and the nest  15  is minimized or eliminated. This can be achieved in a number of ways. For example, the surface of the nest  15  in contact with the adhesive layer can be made of a material to which the adhesive does not stick. Alternatively, the adhesive can be pressure sensitive and the head and nest  15  can be shaped to limit contact between the support sheet  14  and nest  15 . Another, simple alternative is that the adhesive coating can be present on the component  16 , rather than the support sheet  14 . 
     The camera body  18  is then provided ( 114 ) in a predetermined location, in a nest or other support  15 . The component-bearing-label  128  and adhered component  16  are then precisely positioned ( 116 ) relative to the camera body  18 . This can be achieved by moving the labeler head  48  and retained support sheet  14  and component  16 , while holding the body  18  in a fixed position; but is more easily accomplished by replacing the component nest  15  with the workpiece nest  15 . Using a conveyor  13 , component nests and workpiece nests can be alternated in sequence and can be advanced under the labeler head  48  as needed. 
     The labeler head  48  is next driven toward the body  18  and the component-bearing-label  128  and component  16  are pressed ( 118 ) against the camera body  18 . The pressing of the component-bearing-label  128  and component  16  against the body can be provided by the movement of the labeler head  48 . Alternatively, a pulse of higher pressure air can be used to urge the support sheet and adhered component against the body  18 . The adhered component  16  moves with the support sheet  14  and is pressed into position at the same time. 
     In a particular embodiment, the body or the nest  15  has an opening or other pilot feature  92  about which support sheet  14  is to be accurately positioned. In that case, the labeler head  48  is moved toward body  18 , or vice versa, to permit a locator pin  72 , which preferably is tapered as illustrated, to enter opening  92 . The taper on locator pin  72  can be used to finely position body  18  in alignment with the labeler head  48 . Then, as the labeler head  48  is moved into close proximity with the body, locator pin  72  engages opening  92  and retracts against the force of spring  82 ; so that, support sheet  14  is accurately applied about opening  92 . 
     After the support sheet  14  is pressed against the workpiece, the labeler head  48  is withdrawn ( 120 ) relative to the body  118 . In the embodiment shown in FIG. 1, the component-bearing-label  128  remains adhered to the body  18  and the component  16  remains in place on the body  18 . Further assembly procedures, testing, and the like can continue from this point. Referring now to FIG. 2, steps ( 116 ) and subsequent are illustrated for the method in which the support sheet  14  is a carrier  14   b.  The same procedure is followed and the same considerations apply as in FIG. 1 with the exception that, after the labeler head  48  is withdrawn ( 120 ), the carrier  14   b  is removed ( 122 ) from the body  18  and component  16 . The carrier  14   b  can be reused or discarded. The component  16  adheres to both the carrier  14   b  and the body  18 . The adherence to the body  18  is greater. This can be achieved in a variety of ways. For example, the component can be solvent welded or sonic welded or mechanically fastened to the body after positioning using a carrier having a layer of peelable pressure sensitive adhesive. The strength of the bond provided by the adhesive is less than the strength of the bonding provided by the other methods. High strength adhesives, such as curable epoxy adhesives can also be used in place of the welding and mechanical fastening. 
     Bernoulli effect labeler heads  48  and labeling equipment suitable for the methods above-disclosed relating to carriers  14   b  and labels  14   a,  are disclosed in U.S. Pat. No. 5,472,543. (The term “support sheet  14 ” is used generically to refer to the carrier and various labels disclosed herein.) The labeler head  48  comprises a main member  50  having a support surface  52  which may be flat, or convex and substantially cylindrical with an axis of curvature. A plenum  54  within the main member  50  communicates with a plurality of bores  56  extending from the plenum  54  through the support surface  52 . The bores  56  are angled with respect to the support surface  52  and are arranged in an array so that jets of gas issuing from the array will cause a support sheet  14  to be drawn onto the support surface  52  when the support sheet  14  is presented to the support surface  52  and a first side of the support sheet  14  is brought into close proximity of the jets, thereby causing a zone of reduced gas pressure to be formed between the support surface and the first side of the support sheet  14  and establishing a pressure differential across the support sheet  14  to hold the support sheet  14  on a film of gas flowing over the support surface. A gas supply (not shown) provides a flow of gas into the plenum and through the angled bores  56 . The gas supply provides pulses of higher pressure gas to propel support sheets  14  against the camera body  18  to be labeled and can provide a vacuum to the labeler head  48  as necessary to hold support sheet  14 . 
     In the apparatus, an elongated carrier strip  12  has a surface having low affinity for the adhesive-backed side of a plurality of pressure-sensitive support sheets  14 . Display sides of the support sheets  14  face outward from the carrier strip  12 . Support sheets  14  can be of practically any shape and are moderately stiff, to facilitate ready removal from the carrier strip  12 . The carrier strip is wound in a large roll  24  prior to support sheet removal. The used carrier strip  12 , depleted of support sheets  120 , is likewise wound in a roll  26 . The rolls  24 , 26  are mounted to the apparatus  10  for rotation such that strip  12  is pulled around an idler roller  20  and then around the edge of a peeler plate  22 . Because the adhesive backing on support sheets  14  has a low affinity for the surface of strip  12  and because support sheets  14  have a certain resistance to bending, the support sheets  14  will release gradually and automatically from strip  12  as the strip passes around the edge of the peeler plate  22  and are presented essentially tangentially to the labeler head  48 . The labeler head  48  is reciprocated in directions indicated by double-headed arrow  28  by a drive  29 . The component  16  and body  18  are each supplied in a supportive nest  15  that rests on a bracing or conveyor (not separately designated). 
     The main member  50  of the labeler head  48  is a material such as metal or rigid plastic or a resilient material. The support surface  52  is smooth and typically flat. Within main member  50 , a plenum  54  communicates with a plurality of bores  56  which extend from plenum  50  to support surface  52 . In a particular embodiment of the invention, bores  56  have a diameter in the range of 0.012 to 0.032 inch (0.030 to 0.081 cm) and are set at an angle to support surface  52  in the range of 5 to 45 degrees. A port  58  is provided through main member  50  to connect plenum  54  to the gas supply to provide pressurized air or subatmospheric pressure. Bores  56  are arranged in an array so that jets of gas issuing from the bores will cause support sheet  14  to be drawn onto support surface  52  when the support sheet  14  is presented to the support surface and its display side is brought into close proximity with the jets of gas. The flow of gas causes a zone of reduced gas pressure to be formed between support surface  52  and support sheet  14 , in accordance with the Bernoulli Effect, thereby establishing a pressure differential across the support sheet  14  to hold the support sheet  14  in position on a film of gas flowing over the support surface. The array is also configured so that, once released, support sheet  14  will move relative to support surface  52  and reposition itself accurately against one or more stops  60  provided on or adjacent the support surface. Just as shown in FIGS.  4  and  11 - 19 , with the labeler head of FIGS. 4-7, support sheet  14  covers the portion of the array of bores  56  which are at least partially directed toward stops  60 , when the support sheet  14  is positioned against the stops. Thus, the rear or upstream edge of the support sheet  14  is not subjected to air flows which could dislodge it from its position against the stops. Stops  60  can be supported on resilient springs  61 , which allow the stops to be depressed to the level of support surface  52  during support sheet  14  application. Preferably, stops  60  are made from a material to which the adhesive of the support sheets  14  will not stick readily, such as Rulon, a plastic material made by Dixon Industries Corp. of Bristol, R.I. U.S.A. 
     FIGS. 6-7 illustrate another labeler head  48  also useful with the apparatus  10 , in which flat support surface  52  is replaced by a resilient insert  62  of a material such as silicon rubber which has cylindrical, convex support surface  64  having an axis of curvature transverse to the direction from which support sheet  14  is fed to labeler head  48 . A pair of stop pins or abutments  66  are provided on one side of support surface  64 . Stop pins  66  preferably also are made from a non-stick material such as Rulon. In a particular embodiment, at least a portion of bores  56  are angled so that their jets of gas are directed at least partially toward stop pins  66  and do not oppose movement of support sheet  14  onto the labeler head  48 . By “at least partially toward” is meant that none of the air jets includes a vector component which would oppose movement of the support sheet  14  across support surface  64 . For round support sheets  14 , the jets from bores  56  can be symmetrically placed on either side of the path of the support sheet  14  onto the labeler head  48 . Round support sheets  14  upon release will move across support surface  64  into accurate engagement with stop pins  66 . The support sheet  14  may be provided with a radially inwardly or outwardly extending feature which is engaged by the means for stopping. The support sheet  14  may have a central aperture; and the main member  50  may have a locator pin positioned centrally of the array, the pin being sized to pass through the aperture of the support sheet  14  and preferably being retractable. Non-symmetric arrays of bores are also useful, for example, with rectangular support sheets  14 . The resilient material of insert  62  and the cylindrical shape of support surface  64  ensure that when the labeler head  48  is pressed against an workpiece to apply support sheet  14 , essentially line contact is first established due to the cylindrical shape and then the insert compresses, so that the support sheet  14  is smoothly applied without bubbles or wrinkles. 
     FIG. 8 shows a modification of the labeler head of FIGS. 6-7. Within main member  50 , a second plenum  55  communicates with one or more bores  57  which extend from plenum  55  to support surface  64 . Such a second plenum and bores also may be included in the other labeler heads  48  discussed. A port  59  is provided from plenum  55  to a source of pressurized air; so that, a blast of air through bores  57  may be used to blow the support sheet  14  onto the workpiece to be labeled. 
     FIGS. 9-10 illustrate typical arrays of bores  56  for labeler heads  48  of FIGS. 4-8, having flat support surfaces  52  approximately 0.6 and 1.0 inch (1.52 and 2.54 cm), respectively, in width (“W” in FIGS.  12 - 13 ). The number of bores depends upon the area and weight of the support sheet  14 . The arrows indicate the direction of the jets from bores  56  toward stops  60 , preferably so that no vector component of any jet will oppose movement of support sheet  14  onto support surface  52 . For round support sheets  14 , the jets preferably are symmetrically placed relative to the path of the support sheet  14 . Thus, round support sheets  14  upon release will move across support surface  52  into accurate engagement with stops  60 . Similar arrays of bores may be used for support sheets  14  of other shapes. 
     FIGS. 11-14 illustrate another labeler head  48  which is suited for applying support sheets  14  having a central aperture  68  and a radially inwardly extending feature such as a notch  70  extending over an arc of the circumference of the support sheet  14 . In this case, main member  50  is provided with a centrally positioned, tapered locator pin  72  which extends from support surface  52 . The diameter of locator pin  72  preferably is only slightly smaller than that of central aperture  68 , to accurately center the support sheet  14  on the labeler head  48 . Surrounding locator pin  72  is an array of angled bores  74  whose jets extend in generally the same sense or circular direction about locator pin  72 . When support sheet  14  is released so that locator pin  72  enters aperture  68 , the support sheet  14  will move down onto and spin around locator pin  72  until notch  70  settles over an axially extending stop or abutment  76 , thereby stopping movement of the support sheet  14  and accurately centering and angularly positioning it for application. As shown in FIG. 11, support sheet  14  covers the portion of the array of bores  74  which are at least partially directed toward stop  76 , when the support sheet  14  is positioned against the stop. Thus, the circumferential edge of the support sheet  14  is not subjected to air flows which could dislodge it from its position against the stop. Preferably abutment  76  is retractable during application of the support sheet  14 , (not illustrated). As shown in FIGS. 13-14, main member  50  comprises a central stepped bore  72  surrounded by plenum  54 , in which locator pin  72  is slidably mounted. A head  80  on the locator pin is pressed against by a spring  82 ; so that, locator pin  72  is retractable but is biased to extend beyond support surface  52  as illustrated. As will be discussed further with respect to FIG. 18, the retractability of locator pin  72  facilitates use of labeler head  48  to accurately place support sheet  14  around an opening in the camera body  18  to be labeled. Subatmospheric pressure can be applied to plenum  54  after the support sheet  14  has been acquired and repositioned. 
     FIGS. 15-19 illustrate another labeler head  48  which also is suited for applying support sheets  14  having a central aperture  68  and a peripheral notch  70 . In this instance, locator pin  72  can be withdrawn below support surface  52  by any convenient means such as a solenoid or air cylinder (not illustrated), to permit support sheet  14  to be presented and accurately positioned in a different manner. Thus, the diameter of locator pin  72  can be substantially less than that of aperture  68 . To facilitate adjustment of the lateral positions of stops  60  and to allow the stops to be depressed to the level of support surface  52 , support surface  52  preferably ends at a recess having an edge  84  which along a portion of its length is shaped geometrically similarly to the portion of support sheet  14  comprising notch  70 . Opposite this portion of edge  84  and extended over the recess are stops  60 , laterally positioned so that the first stop can engage one side of notch  70  and the second stop can engage the periphery of support sheet  14  on the opposite side of notch  70  from the first stop, as seen most clearly in FIGS. 18 and 21. The support sheet  14  is presented to support surface  52  along a path directly toward stops  60 . Rather than the circular array of jets of the embodiment of FIGS. 11-14, a first pair of bores  86  are provided on the opposite side of locator pin  72  from stops  60  and are directed at angles toward opposite sides of locator pin  72 ; a second pair of bores  88  are directed directly toward stops  60  on opposite sides of locator pin  72 ; and a single, angular orientation bore  90  nearest stops  60  is directed at an angle toward the more distant of stops  60 . Bore  90  may be positioned on either side of the path of support sheet  14 . In a particular embodiment, none of the jets includes a vector force component which would oppose movement of the support sheet  14  across support surface  52 . Support surface  52  preferably is flat but also may have a cylindrical, convex shape of the type shown in FIGS. 6-7. With this arrangement, once locator pin  72  has been withdrawn, a support sheet  14  presented in the direction shown will be moved by jets  86 ,  88  across support surface  52  toward stops  60  and will be turned by jet  90 ; so that, stops  60  accurately engage notch  70  and the periphery of the support sheet  14 . Locator pin  72  can then be extended through central aperture  68 . As shown in FIGS. 15 and 18, in the embodiment of FIGS. 15-19 support sheet  14  covers the portion of the array of bores  86 ,  88 ,  90  which are at least partially directed toward stops  60 , when the support sheet  14  is positioned against the stops. Thus, the circumferential edge of the support sheet  14  is not subjected to air flows which could dislodge it from its position against the stops. Support sheets  14  of different shapes may be acquired and repositioned using somewhat different arrays of jets and stops. 
     Many different types of components  16  can be joined to the body  18  of the camera  11  using the component positioning method. Support sheets  14  and components  16  can be critically positioned; that is, attached at precise locations with tolerances of ±0.3 mm. Tolerances of 0.2 mm or less and 0.1 mm or less can be provided by careful tolerancing of all manufacturing components or by culling of cameras with the greatest variance, or both. 
     Critical positioning can be a requirement of an individual component  16  or can be required to accurately position a plurality of different, spaced-apart components  16 . Detailed features of the components  16  can vary and a single camera  11  can include a plurality of different types of components  16 . The same support sheet  14  can be shared by more than one component  16  or individual support sheets  14  can be used with individual components  16 . For convenience, cameras  11  having critically positioned components are described below in terms of a camera  11  having multiple subsystems  100  of the invention and a single support sheet  14 . It will be understood that like considerations apply to other embodiments. 
     Camera Having Component-bearing-label with Optical Component 
     Referring now particularly to FIGS. 20-29, a camera  11  has a body  18  having boundary parts  123  that define one or more passages  124  and comprise one or more optical subsystems  100   a.  An component-bearing-label  128  has an attachment portion  126  that is adhered to the body  18  and one or more optical components  125 . Each optical component  125  can be a single optical element or an assemblage of multiple optical elements. For convenience, the camera  11  is generally discussed here as if an component-bearing-label  128  was limited to a single optical component  125 . It will be understood that, as the figures illustrate, an component-bearing-label  128  is not limited to a single optical component. It will also be understood that like considerations apply to cameras  11  having more than one component-bearing-label and different combinations of component-bearing-labels, optical elements and components. 
     In addition to the optical component or components  125  and the attachment portion  126 , the component-bearing-label  128  can optionally also include an ancillary portion (not shown) that is unattached to the body  18  or component  16 ; but this is generally not preferred since such an ancillary portion is less supported and has a greater risk of being torn or otherwise damaged during use. 
     The optical component  125  is of one-piece with the attachment portion  126  of the component-bearing-label  128  and is inseparable from the attachment portion  126  without damage to the component. The optical component can be unitary; that is, made as one-piece with and continuous with the remainder of the component-bearing-label  128 , differing only in optical characteristics. The optical component can also be a discrete item, adhered to the attachment portion  126 . In the latter case, the attachment portion  126  can be part or all of an component-bearing-label  128 , as above discussed. 
     The optical component  125  is located on the camera  11  so as to function with a respective optical subsystem  100   a.  In addition to boundary parts  123 , an optical subsystem  100   a  can also include other parts, such as additional optical components that are not part of the component-bearing-label  128 . Each optical component  125  is located at an outer end  130  of a respective passage  124  in optical alignment with the optical subsystem  100   a.  For example, in FIGS. 27-28, the optical components  125  have optical axes that are coextensive with a centerline of passage  124 . 
     A single component-bearing-label  128  can provide multiple optical components  125  and can provide both unitary and discrete optical components  125 . Individual, spaced apart attachment portions  126  can be provided for individual optical components  125 , but it is preferred that the attachment portion  126  is continuous. The attachment portion  126  is preferably compliant unless use is limited to a flat surface of the body  18 . 
     The optical component  125  can be centerless or can be centered on an optical axis  132 . Centerless optical components  125  include transparent plates and filters having no power. Centered optical components  125  have a power or fiducials or other features that define an optical axis  132  and require alignment of the optical axis  132  and the passage  124 . The optical axis  132  is generally centered in the passage  124 , but may be located off center in a predetermined manner. In either case, misalignment would compromise camera function. Centered components must be precisely and accurately positioned on the camera body  18 . Centerless components can be oversize and thus not need precise and accurate positioning. Alternatively, centerless components may require precise and accurate positioning as a result of mechanical constraints due to the shapes of the optical component and the end of the respective passage  124 . 
     Referring now particularly to FIGS. 20-21 and  24 - 25 , the body  18  of the camera  11  has a film counter  134  that is located interior to the outside surface  135  of the camera  11 . The film counter  134  is driven by a film transport (not shown). A passage  124 , defined by the body  18 , has an outer end  130  at the outside surface  135  of the body  18  and an inner end  136  aligned with and closely adjoining the film counter  134 . The component-bearing-label  128  includes a counter window  125   a  that makes visible indicia on the counter indicating film usage. The counter window  125   a  can be a transparent area lacking optical power, but is preferably a magnifier. A fresnel lens  125   a  that acts as a magnifier is preferred. To keep the outside  135  of the camera  11  smooth, the fresnel lens extends inward into the outer end  130  of the passage  124  toward the counter  134  from an outer surface  192  of the component-bearing-label  128 . 
     Referring now particularly to FIGS. 20-23 and  26 - 27 , the body  18  of the camera  11  has a viewfinder housing  138  that defines a passage  124  having two opposed ends  130 , 136  adjoining the outside surface  135  of the body  18 . In FIG. 27, the component-bearing-label  128  includes a pair of optical components  125  in the form of viewfinder lenses  125   b,  which are disposed in the ends  130 , 136  of passage  124 . One of the lenses  125   b  has a fiducial pattern  140  indicating a picture center (dashed circle) and margins (chevrons). The optical axis  132  of the optical components  125   b  is coextensive with a longitudinal axis of the passage  124 . In FIG. 26, the component-bearing-label  128  includes only one of the viewfinder lenses  125   b.  The other lens  139  of the viewfinder is not part of the component-bearing-label  128 , but rather part of the viewfinder subsystem  100   a.  In place of the second viewfinder lens  125   b,  the component-bearing-label  128  has a centerless optical component such as a transparent window or filter  141 . 
     Referring now particularly to FIGS. 20-21 and  27   a,  the body  18  has a flash unit  141  that includes a flash reflector  142  and a circuit board  143  located interior to outside surface  135 . A passage  124 , defined by the body  18  has an outer end  130  at the outside surface  135  and an inner end  136  that is aligned with and closely adjoins the flash reflector  142 . The optical component  125  is a flash lens  125   c.  The flash lens  125   c  is aligned with a cylindrical flash tube  144  mounted in the reflector  142 . 
     Referring now particularly to FIGS. 28-28 a,  a camera  11  has a casing  146  that includes a frame  148  and front and rear covers  150 , 152  joined over the frame  148 . The casing  146  encloses a film area  154  that includes an exposure chamber  156  to which light is directed by the taking lens  125   d  for picture taking. Within the casing  146 , in the film area  154 , unexposed film  160  is moved from a first film chamber  162 , across the exposure chamber  156 , to a second film chamber  164 . The type of film  160  and manner of film transport is not critical. For example, a one or two chamber film cartridge or a cartridgeless film roll can be used. Film can be prewind and be returned to a film cartridge at the time of film exposure, or rewinding after exposure can be required. The embodiment illustrated is a one-time use camera  11 , in which a film roll  166  housed in an otherwise empty film supply chamber  162 , is moved by a film transport (indicated schematically by box  168 ) across the exposure chamber  156  to a film cartridge  170  housed in a film cartridge chamber  164 . The exposure chamber  156  is between the opposed film chambers  162 , 164  and has an exposure chamber  156  through which light is admitted from the taking lens  158  when film exposures are made. The chambers  156 , 162 , 164  are parts of the frame  148 . Joined to the frame  148  are various camera components  172  (illustrated by boxes in FIG. 27 b ) that, together with the frame  148 , comprise a frame assembly  149 . Examples of such components include a viewfinder, a flash unit, an shutter mechanism, and the film transport  168 . The components  172  include appropriate control features that extend through the casing  146 . The shutter mechanism includes a shutter button. The film transport  144  includes a thumbwheel or advance lever. Suitable components and other features of the camera  11  that are not illustrated, are well known to those of skill in the art. Camera features described in this paragraph can be present in the other cameras disclosed elsewhere herein. 
     The frame  148  includes a lens mount  174 . The lens mount  174 , shown is a continuous part of the frame  148  and includes an aperture stop  175  that surrounds an aperture opening  176 . The lens mount  174 , as a whole, or just the aperture stop  175  can also be provided as separate parts that are assembled with the rest of the frame  148 . The camera  11  has an internal component-bearing-label  128  a adhered to the lens mount  174 . The component-bearing-label  128  a faces, but is interior to the front cover  150 . A second, external component-bearing-label  128 , like those discussed elsewhere herein, can also be present. The component-bearing-label  128  includes an optical component  125  in the form of a taking lens element  125   d.  The component-bearing-label  128  is attached to the frame  148 , such that the taking lens element  125   d,  aperture opening  176 , and any other related parts, such as an optional second lens element  178  all define a single optical axis  132 , within the tolerances of Bernoulli labelling methods and apparatus like those above disclosed. An alternative embodiment shown in FIGS. 29-29 a  has similar features, but the adjunct label  128  including the taking lens element  125   d  is external to a front cover  150 . The lens mount  174  is part of the front cover rather than the frame. 
     Camera Having Component-bearing-label with Electrical Component 
     Referring now particularly to FIGS. 30-37 and  42 - 43 , a camera  11  has an electrical subsystem  100   b.  The electrical subsystem  100  has first and second leads  180 , 182  that extend to the outside surface  135  of the body  18  of the camera  11 . An component-bearing-label  128  has an attachment portion  126  that is adhered to the outside surface  135  and an electrical component  184  that is joined to the attachment portion  126 . The electrical component  184  has first and second terminals  186 , 188 . The attachment portion  126  holds the terminals  186 , 188  against the leads  180 , 182  in electrically conductive contact. The electrical component  184  can be of one-piece with the attachment portion  126  or a discrete part in the same manner as the optical components  125  above-discussed. 
     The electrical subsystem  100   b  and electrical component  184  together form an electrical system that provides a particular function or set of functions, such as the functions of an electronic flash or power supply or controller. The function or functions are enabled when the electrical subsystem  100   b  and electrical component  184  are operatively connected and are disabled when the electrical subsystem  100   b  and electrical component  184  are disconnected. 
     For convenience, the camera  11  is generally discussed herein in terms of a single electrical subsystem  100  and a single attachment portion  126  bearing one electrical component  184 . This is not limiting. A camera  11  can have multiple electrical subsystems  100  each having its own associated electrical component  184  or multiple electrical subsystems  100  can share a common electrical component  184 . A single attachment portion  126  can include multiple electrical components  16  or each electrical component  184  can have a separate attachment portion  126 . A camera  11  can also include one or more conventional electrical systems that do not have electrical components  16  provided by an component-bearing-label  128 . The same component-bearing-label  128 , as shown in FIG. 30, can have both electrical and optical components  184 , 125 . It will be understood that different combinations of component-bearing-labels and components can be provided in the same manner as the described embodiments. 
     The camera  11  is also generally described herein in terms of an component-bearing-label  128  mounted on the outside surface  135  of the body  18 . The component-bearing-label can be mounted on an inside surface of a cover or on the frame. This is not currently preferred, since it can make placement of electrical subsystem leads more difficult. 
     The component-bearing-label  125  has an inner surface  190  in contact with the body  18  and an outer surface  192  facing outward. The attachment portion  126  of the component-bearing-label  128  can fully cover an electrical component  184  such that the electrical component  184  is interior to the outer surface  192 . The attachment portion  126  of the component-bearing-label  128  can also have an opening (not separately illustrated) through which part of the electrical component  184  is exposed. The component-bearing-label  128  has multiple layers; the innermost of which is a layer of adhesive. Pressure-sensitive adhesive is convenient for this purpose, but other kinds of adhesives can be used. 
     The electrical component  184  can be rigid or flexible and can be flat and similar in thickness to the attachment portion  126  of the component-bearing-label  128  or three-dimensional with a greater thickness than the attachment portion  126  of the component-bearing-label  128 . Flexible, flat electrical components  16  are preferred, since such electrical components  16  are easy to position anywhere on the body  18  of the camera  11 . Electrical components  16  can be uninsulated if positioned interior to the attachment portion  126  of the component-bearing-label  128 , as shown in FIG.  30 . Insulation is provided by the attachment portion  126  and the body  18 . If the component-bearing-label  128  has multiple layers, then the electrical component  184  can be positioned between layers (not shown). In FIG. 30, the electrical component  184  is a circuit trace, that is, a conductive line deposited on the inner surface  190  of the insulating attachment portion  126 . 
     The nature of the electrical component  184  is largely a practical question. The electrical component  184  can be a single conductor, an electrical system lacking only a single conductor or anything in between. The selection of a particular electrical component  184  requires a balance of a number of competing considerations. For example, an electrical component  184  could be reusable, but it is expected that an electrical component  184  will be used once and then discarded with the remainder of the component-bearing-label  128  prior to camera  11  reloading. Another consideration is that the electrical component  184  is on the outside surface  135  of the body  18  of the camera  11  and is, thus, subject to wear and damage. These considerations argue for the use of electrical components  16  that are inexpensive and require a minimal expenditure of resources. On the other hand, assembly of the electrical component  184  on the camera body  18  is simple, since the electrical component  184  is joined to and assembled with the attachment portion  126  of the component-bearing-label  128 . This consideration argues in favor of the use of more complex electrical components  16 . Other considerations to be considered include esthetics and overall value to the user. 
     Referring to FIGS. 30-33, the electrical component  184  is a circuit trace  184   a  and the subsystem  100   c  is the circuit elements of a flash system. The flash system is disabled if the circuit trace  184   a  is disrupted or removed. Referring to FIGS. 36-37, the electrical component  184  is a voltage indicator  184   b  that displays the charge on the flash capacitor (not illustrated) of the flash system. Strength indicators usable on disposable dry storage batteries are suitable for use as the voltage indicator. For example, U.S. Pat. No. 5,789,100, hereby incorporated herein by reference, discloses a wide variety of indicators including ones using shape memory alloys, color indicating materials, liquid crystal displays, and electroluminescent materials such as organic electroluminescent materials. 
     Indicators used on batteries generally have a switch which must be actuated to operate the indicator. The switch prevents battery drain during storage. In the camera  11  having the flash circuit shown in FIG. 36-37, a switch is unnecessary; since the indicator is isolated from the battery when the flash is not being used. This flash circuit is suitable for an indicator, such as a liquid crystal display, that requires a voltage much lower than the voltage across the flash capacitor. Other suitable flash circuits are well known to those of skill in the art. The flash system can include a battery indicator as shown in, in addition to, or instead of the capacitor charge indicator. In this case, a switch would be connected to the indicator to prevent battery drain. 
     Referring again to FIGS. 36-37, a currently preferred voltage indicator is substantially planar and has a two-dimensional indicator face. This flat shape allows easy placement on a variety of locations on a flat or curved camera body  18 . The two-dimensional indicator face is easy for the user to read. The voltage indicator has a liquid crystal display and electrical connectors to the flash subsystem  100 . The liquid crystal display has, a pair of opposed electrodes and a single liquid crystal cell or an array of liquid crystal cells disposed between the electrodes. The electrodes are electrically connected to the flash subsystem  100  through the terminals  186 , 188 . Each cell is subject to a visible phase change responsive to the application of a particular voltage across the terminals  186 , 188 . With the single cell liquid crystal display, the voltage corresponds to the presence of a full charge on the flash capacitor and the voltage display is consulted by the user of the camera  11  in the same manner as a flash ready light. With the multiple cell liquid crystal display, the cells respond to a sequence of different voltages corresponding to different partial charges and a full charge on the flash capacitor. The outside surface of the component-bearing-label  128  has indicia, aligned with the different cells, that indicate flash distances appropriate for the different charge states. The user can take a picture when a sufficient charge is reached for the distance required for flash coverage of the subject matter. Other indicators than a liquid crystal display can also be used similarly to provide an incremental readout proportional to a voltage across the terminals  186 , 188 . 
     Although the electrical component is generally described herein in terms of a pair of terminals, the number of terminals and leads for a particular component can be larger or smaller. The terminals  186 , 188  and leads  180 , 182  can have a variety of configurations. FIGS. 42 a - 42   f  illustrates some examples of these configurations for a single terminal-lead pair  191 . It is highly preferred that the terminals  186 , 188  and leads  180 , 182  contact each other in non-mating relation as shown in FIGS. 42 a - 42   e.  Mating terminal-lead pairs  191 , such as the pair shown in FIG. 42 f,  are not readily usable with Bernoulli effect labeling. Terminals  186 , 188  and respective leads  180 , 182  can contact each other directly, as shown in FIGS. 42 a - 42   d  for non-mating relation, and FIG. 42 f  for mating relation. Terminals  186 , 188  and respective leads  180 , 182  can contact indirectly through an intermediate conductor  193 , in mating or non-mating relation. (As used herein, “non-mating relation” is exclusive of mating contact between two parts and is also exclusive of contact between first and second parts through an intermediate where a first part and second parts are each in mating relation with the intermediate.) Indirect contact between respective terminals  186 , 188  and leads  180 , 182  is more complex than direct contact and is therefore not preferred. It is further preferred that respective terminals  186 , 188  and leads  180 , 182  are simply butted together and held in place by the adhesion of the attachment portion  126  of the component-bearing-label  128  to the body  18 . To help maintain abutting relation one or both members of a terminal-lead pair  191  can be resiliently biased toward the other, by an internal spring  193  (shown in FIG. 42 d ), an external spring (not shown) or inherent resilience of the material of the terminal  186 , 188  or lead  180 , 182 . 
     The parts of the terminals  186 , 188  and leads  180 , 182  that are butted together and provide a conductive path are referred to herein as contact portions  194 , 196 , respectively. Contact portions  194 , 196  of non-mating terminal-lead pairs  191  shown in the figures are flat. Contact portions  194 , 196  can be curved. Referring to FIG. 42 b,  for example, the leads  180 , 182  are wires that extend through holes in the body  18  and have contact portions  196  as the ends of the wires, and the contact portions  194  of the terminals  186 , 188  are small pads on the inner surface  190  of the component-bearing-label  128 . 
     Contact portions  194 , 196  of terminal-lead pairs can be the same size or can differ. The size of each contact portion  194 , 196  is a function of the electrical load and the area of contact between the members of the terminal-lead pair  191 . It is preferred, for reasons of circuit design and manufacturing economy, that the contact portions  194 , 196  for respective terminals  186 , 188  and leads  180 , 182  are relatively close to each other in size and small relative to the size of the component-bearing-label  128 . Small contact portions  194 , 196  are also easier to hold together so as to provide good electrical contact. With small contact portions  194 , 196 , the area of adhesion between the attachment portion  126  and the body  18  in the immediate vicinity of the contact portions  194 , 196  can be many times the size of the contact portions  194 , 196 . Small contact portions  194 , 196  are also favored to reduce electrical resistance and esthetic constraints on design of the component-bearing-label. A preferred terminal-lead pair  191  has a smaller contact portion  194  or  196  that has an area that is more than 25 percent of the area of the other contact portion  196  or  194 , or more preferably 50 percent, or still more preferably 75 percent. The same reasons support maximizing the percentage of each contact portion  194  or  196  in contact with the other  196  or  194 . In a preferred embodiment, each contact portion  194  and  196  has more than 25 percent of its area in contact with the other contact portion  196  or  194 . Fifty percent in contact is more preferred and 75 percent still more preferred. 
     With many labeling techniques, the minimum tolerance for a center to center spacing for the members of a terminal-lead contact pair is 0.8 mm. For small leads and terminals, Bernoulli labelling methods and apparatus are preferred, as above discussed, to provide a terminal center to lead center tolerance of 0.3 mm, or 0.2 mm, or 0.1 m. 
     In the embodiments previously discussed, each terminal-lead pair  191  is positioned independently; however, terminals  186 , 188  or leads  180 , 182  or both can be ganged in a regular array or other pattern. In FIGS. 43-44, terminals  186 , 188  are coaxial with one of the terminals cylindrical and the other shaped like a circular tube. An insulating sheathe  198  separates the two terminals. The leads  180 - 182  have the same configuration, including another insulating sheathe  198 , and preferably the same dimensions. In a particular embodiment the radial thickness of the sheathes and the tubular terminal and lead are all equal to the radius of the cylindrical terminal and lead. It is preferred that the radius is 0.6 mm, or more preferably 0.4 mm, or still more preferably 0.2 mm. 
     Camera Having Component-bearing-label Including Breakable Component 
     Referring now to FIGS. 20-23,  28 - 29 , and  34 - 37 , the body  18  of the camera  11  includes a primary cover section  200  and at least one openable or secondary cover section  202 . The openable cover section  202  is movable relative to the primary cover section  200  from a closed position to an unclosed position to open the body  18 . The openable cover section  202  can be a door, such as a film door  202   a  that is opened or removed for removal of an exposed film cartridge  204  or a battery door (not shown) that is opened or removed for removal of a battery, or a cover, such as a back cover  152  that is separated from the front cover  150  and frame assembly to open the camera  11 . An component-bearing-label  128  overlaps and is, preferably, adhered to the primary cover section  200  and one or more secondary cover sections  202 . The component-bearing-label  128  has an attachment portion  126 . The attachment portion  126  has the features described elsewhere herein. 
     The camera  11  has one or more breakable components  216  joined to the attachment portion  126 . A camera  11  can have multiple component-bearing-labels  128 . Multiple breakable components  216  can be provided on a single attachment portion  126 . Multiple subsystems  100  can be completed by a single component  216 . For convenience, the camera  11  is generally discussed herein as having a single breakable component  216 , single subsystem  100 , and single component-bearing-label  128 . Like considerations apply for multiple items. 
     The breakable component  216  is part of a camera system that provides one or more camera functions. The system includes a subsystem  100  mounted in the body  18 . The breakable component  216  can degrade recycling operations or recycled products, if retained when the camera  11  is recycled. In currently preferred embodiments, the breakable component  216  has the features of an optical component  125  or electrical component  184  as previously described. The subsystem  100  has the features of the corresponding optical subsystem  100   a  or electrical subsystem  100   b.    
     The attachment portion  126  supports the breakable component  216  on the body  18  in operative relation to the respective subsystem  100 . For example, FIGS. 20-23 and  26 - 27  illustrate a breakable component  216  that is a viewfinder lens  125   b.  The respective subsystem  100  includes the viewfinder housing  138 . The system can include a second viewfinder lens  139  that is part of the subsystem  100  or a second viewfinder lens  125   b  that is part of the attachment portion  126 . The latter can also be a breakable component  216 . The viewfinder lens  125   b  is held by the attachment portion  126  in concentric alignment with an optical axis  132  defined by the viewfinder housing  138  and the other viewfinder lens. FIGS. 20-21 also illustrate a breakable component  216  that is a counter window  125   a  over the film counter  134  and another breakable component  216  that is a flash lens  125   c.  The flash lens  125   c  is mounted to the body  18  over a reflector  206 . A flash tube  208  is mounted in the reflector  206  and both flash tube  208  and reflector  206  are supported by a circuit board  210 . 
     In the camera shown in FIGS. 29 and 29 a,  the breakable component is a taking lens element  125   d  that is held on the lens mount  174  by the attachment portion  126 . The taking lens element  125   d  has a line of weakness (indicated by dot-dash line  212 ) resulting from a pair of opposed notches  214 . 
     Referring now to FIGS. 30-37 and  42   a - 44 , the component-bearing-label  128  has a breakable component  216  that is an electrical component  184 . FIGS. 30-35 illustrates breakable components  216  that are circuit traces  184   a.  In FIGS. 36-37, the electrical component  216  is a liquid crystal display. The respective subsystem  100  is an electrical circuit, such as a flash unit. The electrical circuit has first and second electrical leads  180 , 182 . The electrical component  184  has first and second terminals  186 , 188 . The attachment portion  126  of the component-bearing-label  128  holds the terminals  186 , 188  in electrical contact with respective leads  180 , 182 . 
     When the openable cover section  202  is moved from the closed position to the unclosed position, the attachment portion  126  is disrupted from a use configuration to a replacement configuration. In the use configuration, as shown in FIGS. 20,  22 ,  24 - 27   a,    28   a,    29   a - 32 ,  34 , and  36 , the attachment portion  126  is smoothly fit to the body  18  of the camera  11 . When openable cover section  202  is moved to the unclosed position, the attachment portion  126  of the component-bearing-label  128  is tensioned. In response, the attachment portion  126  deforms into a replacement configuration, as shown in FIGS. 21,  23 ,  35 , and  37 . In the embodiments illustrated, during the deformation the attachment portion  126  looses adhesion and deflects outward from the body  18 , stretches, or tears, or some combination of these occur. 
     The tensioning of the attachment portion  126  also tensions the breakable component  216 , which then breaks. The breaking is a disruption that prevents reuse without repair or is irreparable. The extent of tensioning imposed by the attachment portion  126  on the breakable component  216  is predictable, from the geometry of the movement of the openable cover section  202  and the response of the attachment portion  126  to that movement; and the breakable component  216  is selected to fail under that tensioning. The nature of the breakage is not critical. Convenient breakage modes are inelastic stretching and fracture or tearing along a line of weakness such as a tear line or other friable portion. The term “tear line” is used herein to refer to any narrow, linearly extensive feature of an component-bearing-label  128  which is weaker than adjacent portions to the component-bearing-label  128  such that the component-bearing-label  128  yields along the feature, such as a row of spaced perforations or other stress concentrating discontinuities. 
     It is preferred that the breakage is irreparable and catastrophic. The damage incurred in the “irreparable breakage” prevents usage of the component  16  in the same manner that the component  16  was usable before the irreparable breakage. In other words, breakage is irreparable if it is impossible to repair or can only be repaired at a cost in excess of the replacement cost of the item. For example, the viewfinder lens  125   b  shown in FIG. 22 has fiducials  218  that indicate the limits of the image frame when a picture is captured. After irreparable breakage, shown in FIGS. 21 and 23, the viewfinder lens  125   b  cannot be repaired in any practical manner, which would permit all the fiducials  218  to be used to compose a picture. 
     Breaking is catastrophic if a major part of the breakable component  216  has damage that is perceptible by an unaided user on ordinary inspection. Breaking of brittle components  16  or gross inelastic stretching of pliable components  16  is catastrophic. Catastrophic breakage helps ensure that cameras  11  having breakable components  16  are not recycled in degraded or badly repaired form. 
     The attachment portion  126  and breakable component  216  can be made in two pieces with the breakable component  216  being joined to the attachment portion  126  during camera  11  assembly. This is not preferred, however, since there is a risk that the adherence of the breakable component  216  to the attachment portion  126  may fail before the breakable component  216  fails. It is preferred that the attachment portion  126  and breakable component  216  are of one-piece, that is made as a continuous part of single structure. For example, an optical component  125  can be a part of a continuous layer of a multiple layer component-bearing-label  128  and an electrical component  184  can be an area of conductive material deposited on a support that is continuous with the rest of the component-bearing-label  128 . 
     Referring now to FIGS. 20-23, the component-bearing-label  128  has a first breakable component  216  that is a viewfinder lens  125   b  of the camera  11 , a second breakable component  216  that is a flash reflector lens  125   c,  and a third breakable component  216  that is a counter lens  125   a.  When the openable part is opened, the component-bearing-label  128  is stretched inelastically and the viewfinder lens  125   b,  flash reflector lens  125   c,  and counter lens  125   a  are all broken. As shown in the figures, this breaking is by inelastic deformation. This mode of breakage can be impractical for thicker lenses. In that case, a more convenient mode of breakage can be cracking along a line of weakness, as shown in FIGS. 29-29 a.  When the rear cover  152  (which for this embodiment is the openable cover section  202 ) is separated from the rest of the body  18 , the taking lens element  125   d  is tensioned by the attachment portion  126  and breaks along the line of weakness  212 . The attachment portion  126  of the component-bearing-label  128  has a tear line  220  that extends through the notches  214  to the friable area  212  of the lens element  125   d.    
     Referring specifically to FIGS. 20-23, the viewfinder lens  125   b  breaks by inelastic stretching and has the broken configuration shown in FIGS. 21 and 23. The viewfinder lens  125   b  cannot be restored to the unbroken configuration. The damage is catastrophic. The entirety of an image seen through the viewfinder  125   b  is grossly distorted and the fiducials  218  are no longer square. The viewfinder  125   b  cannot be restored and, unrestored, cannot be used to realistically visualize a scene for picture taking. The lens  125   b  has an obvious distortion that will be apparent to anyone recycling the camera  11 . The component-bearing-label  128 , including the viewfinder lens  125   b,  is replaced to recycle the camera  11 . The breakage of the viewfinder lens  125   b  helps ensure that the condition of the lens will be assessed when the camera  11  is recycled. Earlier occurring wear and damage might not otherwise be noticed. Catastrophic damage ensures that the condition of the lens  125   b  will not be easily missed. Irreparable damage ensures that the viewfinder lens  125   b  will be replaced with a new lens when the camera  11  is recycled. In addition to preventing the use of possibly worn or damaged viewfinder lenses, this requirement of a new viewfinder lens helps prevent possible mismatches, after recycling, between the format set for the film reloaded in the camera and the format indicated by the fiducial of the viewfmder lens and light cone of the flash lens. (With some film types, such as Advanced Photo System™ film, the format of the film can be preset by prerecording optical or digital codes. The format determines the aspect ratio of the resulting photographic prints. Standard formats are “C”, “H”, and “P”.) Similar considerations apply to other breakable components commensurate to the risk of damage during ordinary use and risk of misallocation during recycling. For example, unlike the viewfinder lens and flash reflector lens, the counter lens is independent of film type and format, and wear and tear on the counter lens is unlikely to greatly damage functionality except when cameras are subject to severe usage. 
     Referring now to FIGS. 34-35, the circuit trace breaks by tearing along a tear line  220  in the attachment portion  126  that crosses the circuit trace  184   a.  The breakable component  216  of the camera  11  shown in FIGS. 36-37 is a liquid crystal display that breaks in the same manner as the circuit trace. 
     In embodiments having electrical components as breakable components, the openable cover  202 , when opened, disrupts the component-bearing-label  128  sufficiently to interrupt the electrical contact between leads  180 , 182  of an electrical subsystem  100  and terminals  186 , 188  of the electrical component  184 . For example, the flash system can be disabled when the circuit trace is disrupted or removed during camera recycling. This embodiment is useful, for example, in a one-time use camera  11  in which a flash battery is not removed when film is removed for processing. Since the flash circuit is disabled, jostling of used camera  11  bodies during handling for recycling is unlikely to cause the flash circuit to charge and discharge. Such accidental charging and discharging would be wasteful of batteries and distracting to workers. The circuit trace of FIGS. 34-35 is not catastrophically damaged by tearing along the tear line, but tearing of some other electrical components  16  that are more difficult to repair, such as a liquid crystal display, as shown in FIGS. 36-37, is catastrophic. 
     Referring now to FIGS. 38-41, in a one-time use camera recycling method, at a first stage ( 222 ) the camera  11  is opened ( 224 ), breaking ( 226 ) the breakable component  216 , and exposed film is removed ( 228 ) for processing. (The component-bearing-label having the breakable component that is destroyed when the camera  11  is opened, is referred to here as the “original component-bearing-label”.) Destroying ( 226 ) the breakable component  216  disables the camera system that includes the breakable component  216 . For example, as shown in FIGS. 30-31, breaking a component  16  that is a circuit trace severs an electrical connection. 
     The opening ( 224 ) of the camera  11 , that is, that movement of an openable cover section  202  from the closed position to the open position can be required for film removal ( 228 ) or can be separate from film removal. FIG. 30 illustrates a camera  11  having a film door that when opened, breaks breakable components  216  of the component-bearing-label  128 . The steps of the method followed for this camera are given in FIG. 41, with the combined opening and breaking indicated by line ( 230 ). After the exposed film has been removed ( 228 ), the rear cover is separated ( 232 ) from the front cover and frame. 
     FIG. 36 illustrates a camera  11  having front and rear covers that open by separating ( 232 ). The openable cover portion can be extraneous to the camera&#39;s light lock, but it is preferred that the camera  11  is not light tight when the first cover portion is in the unclosed position. Referring to FIGS. 39 and 40, as line  234  is intended to indicate, the breakable component  216  breaks ( 226 ) when the covers are separated ( 232 ). Referring to FIGS. 36 and 39, the camera  11  can have an optional, separate film door that can be opened or removed ( 224 ) without breaking the breakable component  216  and before the covers are separated ( 232 ), to allow film removal. Referring to FIGS. 36 and 40, without the film door, the film is removed after the covers are separated. 
     At a second stage ( 236 ), following opening ( 224 ) of the camera and removal ( 228 )of the film for processing; the camera  11  is recycled by loading ( 238 ) unexposed film, light-tightly closing ( 240 ) the camera  11 , and replacing ( 242 ) the breakable component by applying a replacement component-bearing-label  128  to the camera body  18 . Other procedures used in recycling one-time use cameras  11  can also be followed, such as, replacing covers and/or damaged or worn parts, and cleaning and testing retained parts. Since the replacement component-bearing-label  128  has an intact breakable component  216 , the replacing of the component-bearing-label  128  reenables the earlier disabled camera  11  system. 
     The invention has been described in detail with particular reference to certain preferred embodiments thereof, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention.
