Lens-fitted film unit

A strobe circuit for use in a lens-fitted film unit is composed of a metallic thin plate punched in a circuit pattern; and insulating plate materials covering both obverse and reverse surfaces of the metallinc thin plate; wherein a part of the metallic thin plate is used as a component of the strobe circuit.


What is claimed is:
1. A lens-fitted film unit with a built-in strobe, comprising
a unit main body, in which a photographing member for conducting photographing is incorporated, a strobe circuit, a cover member to cover the unit main body and the strobe circuit;
the strobe circuit comprising a metallic thin plate punched in a circuit pattern, insulating plates covering both obverse and reverse surfaces of the metallic thin plate, and wherein a part of the metallic thin plate is used as a component of the strobe circuit and the metallic thin plate is 0.07-0.2 mm in thickness and the insulating plates are 0.05-0.19 mm in thickness.
2. A lens-fitted film unit with a built-in strobe, comprising
a unit main body, in which a photographing member for conducting photographing is incorporated, a strobe circuit, a cover member to cover the unit main body and the strobe circuit;
the strobe circuit comprising a metallic thin plate punched in a circuit pattern, insulating plates covering both obverse and reverse surfaces of the metallic thin plate, and wherein a part of the metallic thin plate is used as a component of the strobe circuit, said part of the metallic thin plate being bent perpendicularly to the strobe circuit and is used as a switching contact, said switching contact comprising an actuating contact, movable in a direction toward and away from a fixed contact on said strobe circuit in a direction parallel to said strobe circuit.
3. The lens-fitted unit of claim 2 wherein said switching contact and said fixed contact face each other.
4. A lens-fitted film unit with a built-in strobe, comprising
a unit main body, in which a photographing member for conducting photographing is incorporated, a strobe circuit, a cover member to cover the unit main body and the strobe circuit;
the strobe circuit comprising a metallic thin plate punched in a circuit pattern, insulating plates covering both obverse and reverse surfaces of the metallic thin plate, and wherein a part of the metallic thin plate is used as a component of the strobe circuit, the part of the metallic thin plate is bent perpendicularly to the strobe circuit and being used as a contact piece for a battery.
