ABSTRACT:
FIELD OF THE INVENTION
The invention relates generally to the field of photography, and in particular to one-time-use cameras. More specifically, the invention relates to a one-time-use camera with an electronic flash having film identifying indicia which cannot be removed without destroying the flash.
BACKGROUND OF THE INVENTION
Film and cameras that are all in one, commonly referred to as single-use or one-time-use cameras, have become well known. The one-time-use camera is a simple point-and-shoot type comprising an opaque plastic main body part which supports a conventional film cartridge in a cartridge receiving chamber, an unexposed film roll prewound from the film cartridge onto a film take-up spool in a film supply chamber, a fixed-focus taking lens, a film metering mechanism with a rotatably supported metering sprocket that engages the filmstrip, a manually rotatable film winding thumbwheel rotatably engaged with a film spool inside the film cartridge, a single-blade shutter, a manually depressible shutter release button, a rotatable frame counter for indicating the number of exposures remaining to be made on the filmstrip, a direct see-through viewfinder having front and rear viewfinder lenses, and in some models an electronic flash. A pair of opaque plastic front and rear cover parts house the main body part between them to complete the camera unit. The rear cover part connects to the main body part and/or to the front cover part to make the main body part light-tight. A decorative cardboard outer box or label at least partially covers the camera unit and has respective openings for the taking lens, etc.
After each picture is taken with the one-time-use camera, the photographer manually rotates the thumbwheel in a film winding direction to similarly rotate the film spool inside the film cartridge. This winds an exposed frame of the filmstrip into the film cartridge. The rewinding movement of the filmstrip the equivalent of slightly more than one frame width rotates the metering sprocket in engagement with the filmstrip to decrement the frame counter to its next lower-numbered setting and to pivot a metering lever into engagement with the thumbwheel in order to prevent further manual rotation of the thumbwheel. Manually depressing the shutter release button to take another picture pivots the metering lever out of engagement with the thumbwheel to permit renewed rotation of the thumbwheel. When the maximum number of exposures available on the filmstrip have been made, and the filmstrip is completely wound into the film cartridge, the one-time-use camera is given to a photofinisher who tears the outer box off the camera unit, separates the rear cover part from the main body part, and removes the film cartridge with the exposed filmstrip from the cartridge receiving chamber. Then, he removes the exposed filmstrip from the film cartridge to develop the negatives and make prints for the customer. At least some of the used camera parts may be recycled, i.e. reused, to remanufacture the camera.
Prior Art Problem
There is a known problem in the recycling, i.e. reuse, of used camera parts, in that the reused parts may become worn or damaged and therefore should not be reused. Thus, it has been suggested that any worn or damaged parts be purposely fractured to render them visibly different during disassembly of the one-time-use camera to retrieve the exposed film. This allows the worn or damaged parts to be readily identified to be discarded, and prevents them from being erroneously reused.
Also, it has been suggested that the opaque front cover part of a remanufactured one-time-use camera with recycled parts have integrally formed film identifying indicia to visibly identify the particular brand of fresh film inside the camera. This kind of identification promotes brand awareness and, thus, tends to assure that the camera with recycled parts and fresh film is of the highest quality.
The Cross-Referenced Application
The cross-referenced application discloses a one-time-use camera comprising a filmstrip, a concave-shaped flash reflector having a front open end, a flash illumination-producing flash tube inside the flash reflector, and a light-transmitting flash cover-lens over the front open end of the flash reflector. The flash cover-lens has film identifying indicia to identify the filmstrip which are light-transmitting to the same extent as the flash cover-lens in order to transmit flash illumination produced by the flash tube in concert with the flash cover-lens.
SUMMARY OF THE INVENTION
According to one aspect of the invention, a one-time-use camera which comprises a filmstrip, and an electronic flash with a concave-shaped flash reflector having a front open end, a flash illumination-producing flash tube inside the flash reflector, and a light-transmitting flash cover-lens over the front open end of the flash reflector, is characterized in that:
at least one of the flash reflector and the flash cover-lens has film identifying indicia visible from outside the camera to identify the filmstrip and is adhered to the flash tube to prevent the flash reflector and/or flash cover-lens with the film identifying indicia from being separated the said flash tube without breaking the flash tube, whereby removal of the film identifying indicia in effect destroys the electronic flash.
According to another aspect of the invention, a one-time-use camera comprising a filmstrip, a concave-shaped flash reflector having a front open end, a flash illumination-producing flash tube inside the flash reflector, and a light-transmitting flash cover-lens over the front open end of the flash reflector, is characterized in that:
the flash reflector has film identifying indicia to identify the filmstrip which are light-reflecting to the same extent as the flash reflector in order to reflect flash illumination produced by the flash tube in concert with the flash reflector.
