Title: Document feeder
Inventor: HAYAMA HIROTADA
IPC: B65H83/00
Filed: 1987-07-31
Abstract: PURPOSE:To surely detect the feeding state of document by installing a rotating axis coaxially disposing a document detecting member which abuts on the document to be copied that is housed in a document housing member and detects the existence of the document and a sensor part which detects the movement of the angle of one rotation of a follower gear. CONSTITUTION:The rotating axis 4 coaxially disposes the follower gear 40 and the document detecting member 41 and links them. The document detecting member 41 converts the difference between the case it abuts on the document 20 housed in the document housing member 2 and the case it does not abut there into the movement of position and allows the follower gear 40 to rotate and move within the range of a notched part 40b through the rotating axis 4. The sensor part 5 detects the rotation of the follower gear 40. Namely it detects that one cycle of process that all the document 20 is returned to the document housing member 2, after it is carried to the original placing table of a copying device, which is mentioned later, and copied, is completed. Thus, the feeding state of the document can be surely detected.

IPC: H01J61/067
Filed: 1989-07-28
Abstract: PURPOSE:To lengthen the service life of the title lamp and achieve high efficiency by using an electrode comprising at least two metal wires coiled concentrically and reversely. CONSTITUTION:Basket-like coils 11, 12 are obtained by coiling at least two metal wires concentrically and reversely.
