This invention relates to an image sensor with photo sensors (13). An object thereof is to simplify mounting operation of an image sensor chip (12) provided with the photo sensors (13). In order to accomplish this object, according to this invention, the photo sensors (13) and electrodes (15) are disposed on the underside of the image sensor chip (12). The image sensor chip (12) is bonded to the upper side of a transparent substrate (18) by means of a transparent photo-setting type insulating resin (16), so that the electrodes (15) come into contact with circuit conductor layers (17) disposed on the upper side of the transparent substrate (18). With the above-mentioned construction, since fine metal wire (75) by which the electrodes (15) and the circuit conductor layers (17) are connected to each other is not required, mounting operation can be simplified.

摘要:
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.
