In a three-line linear sensor, a first linear sensor (10) without electronic shutter structure and second and third linear sensors (20), (30) with electronic shutter structures (28), (38) being disposed in an axial symmetry fashion are combined and a line spacing (D1) between the first and second linear sensors (10), (20) can be reduced by an amount corresponding to the omitted electronic shutter structure. Also, since the second and third linear sensors (20), (30) are disposed in an axial symmetry fashion, a line spacing (D2) between the second and third linear sensors (20), (30) can be reduced and set to be substantially equal to the above-mentioned line spacing (D1). <IMAGE> |
