Abstract: The biochemical analysis unit has a base plate and absorptive regions. The absorptive regions are surrounded by the base plate formed of materials which shield a radioactive ray and a light. In the absorptive regions are applied and absorbed specific binding substances to be bound with substances derived from a living organism that are labeled with labeling substances for generating the radioactive ray or the light. The base plate prevents the specific binding substances from penetrating in the other absorptive regions. When an analysis of data of the radioactive ray and the light is carried out, an image of the radioactive ray and the light is generated without noises.

The invention is also intended to change over between two circuits that is, a circuit for using a picture element clock regenerated by a PLL circuit as a sampling clock for analog to digital converters and a circuit for using a clock obtained by dividing the picture element clock as a sampling clock for the analog to digital converters to sample video signals with every other plurality of picture elements as an interval. Thus, it is possible to carry out sampling of high definition video signals with high frequencies in addition to common video signals without necessity of raising the operating speed of the sampling circuit.
