Abstract

The invention provides a linear array image sensor and a linear array image reading device. The linear array image sensor comprises a light source, a lens, a plurality of sensor chips, a sensor substrate and a socket. A plurality of photosensitive pixels are arranged on the surface of the sensor chips. The socket is used for providing a power supply and control signals for the sensor and outputing signals of the sensor chips. The sensor chips comprise two rows of sensor chips arranged in parallel. A first row of sensor chips and a second row of sensor chips are arranged in intersection mode. At least one photosensitive pixels of the first row of sensor chips and the second row of sensor chips are located on the same straight line in the direction parallel to the original pattern moving direction. The photosensitive pixels of the first row of sensor chips and the second row of sensor chips are arranged in the effective receiving range of the lens. The linear array image sensor and the linear array image reading device resolve the problem of image information loss in reading of images caused by the fact that gaps are retained between the sensor chips when the sensor chips of the linear array image sensor are assembled, and improve image reading quality.
