    • The present invention relates to a linear beam irradiator, more specifically to a linear beam irradiator for using light conductor, comprising a light conductor having light permeability, a light refraction & reflection area 2 provided on one side face in the longitudinal direction of said light conductor, and a light source 8 provided in a way to cover the light refraction & reflection area 2, as well as a light source disposed at one end or both ends of said light conductor. This construction makes it possible to irradiate a linear light beam from the other side face of the light conductor corresponding to said light refraction & reflection area 2. With this construction, it becomes possible to reduce the deviation of illuminance of said linear light beam, sharply improve the transmission efficiency of light and greatly reduce the number of LED chips disposed at the light source. Moreover, this also enables a cost reduction.
    • 线性光束照射装置技术领域本发明涉及一种直线光束照射装置,更具体地涉及一种使用光导体的直线光束照射装置,其特征在于,包括具有透光性的导光体,设在所述导光体的长度方向的一个侧面上的光折射和反射区域2 以及以覆盖光折射和反射区域2的方式设置的光源8以及设置在所述光导体的一端或两端的光源。 这种结构使得可以从对应于所述光折射和反射区域2的光导体的另一侧面照射线性光束。通过这种结构,可以减少所述线性光束的照度偏差 提高光的传输效率,大大减少设在光源处的LED芯片的数量。 此外,这也可以降低成本。

    • A plurality of pixel circuits arranged in rows and columns, and each of which outputs an electric signal according to an amount of received light; a first column signal line provided for each of the columns, and for sequentially transferring the electric signals from said pixel circuits in a corresponding column; and a holding circuit provided for each of the pixel circuits in each column, and which holds the electric signal transferred through the column signal line in the corresponding column are provided. A holding circuit includes a first capacitor which holds a first electric signal of the corresponding pixel circuit in a reset state; and a second capacitor which holds a second electric signal after the corresponding pixel circuit receives light. A difference circuit calculates a difference between two electric signals held by the first capacitor and the second capacitor in a same holding circuit.
