IPC: H04N1/401
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To provide an image reader by which correcting precision of shading is improved. SOLUTION: An image signal S4 of a form 1 is outputted from an image sensor 4, amplified by an amplifier 5, turned into an image signal S5, a black level of the image signal S5 is clamped to zero V by a black level clamping circuit 6, and then an image signal S6 is outputted.

A corrected value S11 corresponding to an A/D converted pixel is transmitted from a corrected value memory 11 to the correcting operation table memory 10 based on an address S12. Since the results of correcting operation corresponding to the corrected value S11 and the image signal S8 are written in the correcting operation table memory 10, a corrected image signal S10 is outputted, even if the image signal S8 whose level is lowered is inputted.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject frame hampering no fishline operation even with a holding frame subjected to reducing work, by bently forming, under specified conditions, a front side attachment leg provided integratedly on the lower side of the annular holding frame of a fishline guide ring. SOLUTION: First, an annular holding frame 3 for holding a guide ring 11 to be threaded with a fishline is subjected to reducing work so as to afford an axial part 13 and allow a front side attachment leg 5 to extend from the rear end of the axial part 13. Secondly, the front side attachment leg 5 provided integratedly on the lower side of the holding frame 3 is bently formed so that the tip faces on the front side relatively to the resultant holding frame 3 with the axial part 13 side away from the root end 27 as bending initiation end. If the front side attachment leg 5 is bently formed so as not to be projected behind the plane X along the rear end of the axial part 13, a fishline can be prevented from being caught by the leg 5, therefore being favorable.  Besides, if a recess 29 is provided as an adhesive injection port on the rear face of the bending initiation end, an adhesive can be injected easily when the guide ring 11 and the axial part 13 are to be fixed to each other with the adhesive, therefore being favorable.
