Title: Method for identigying size of original
Inventor: YUSE CHIKARA
IPC: H04N1/00
Filed: 1985-09-02
Abstract: PURPOSE:To identify automatically the size of an original by using black/white information of a sensor for detecting the original provided in the range of the specific size of the original. CONSTITUTION:Plural original size identification sensors 21 are provided in the range of B4 size being the size of an original platen 10 to detect contrast information of a pattern. The light from a light emitting section 21a is reflected in the original 11 and reaches a photodetection section. A signal of the photodetection section 21b is inputted to a size identification circuit 22 together with the output from the other sensor 21. When the original placed on the original platen 10 is A4 size, since the output of the sensor 21 is all at a black level, the identification circuit 22 discriminates it as the A4 size. On the other hand, when a white level is detected from any of outputs of the sensor 21, it is discriminated as the B4 size. Thus, the size of an original is identified automatically.

Title: Electric connector
Inventor: YAEGASHI HIROKATSU
IPC: H01R12/79
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To suppress the elastic bending amount of a cover and avoid reduction in contact pressure by inclining a contact part and the cover or an indirect member to a line in which the direction of the contact pressure between them faces upward. SOLUTION: The outer cover of a cable C is removed, a shielded cable C2, a middle cover C3, and a core wire C1 are exposed, the shielded cable C2 is soldered to a solder bar 45, and held at the specified intervals. When the cable C is housed in a groove 32 corresponding to a carrier 30, the core wire C1 is positioned in an inclined part 33 of the groove 32. The carrier 30 is housed in a housing main body 10 with a tapered part 31 faced upward. A cover 40 is pushed downward, and moved at the same time, and a locking part 44 is engaged with a locking groove 14A. Since a contact part 21 presses the core wire C1 against the inclined part 33, the force received by the carrier 30 is accompanied with a horizontal component and the upper component is reduced. The force lifting the carrier 30 is reduced, and bending of the cover 40 is also reduced.  Even if the contact pressure is sufficient, the force lifting upward is small.
