A card connector for use with an electronic appliance through an IC card having a plurality of recesses extending from its front end toward its rear end in parallel with one another and contact pads each being received in the recess. The second siderail body is movably coupled to the first siderail body and configured to rotate between a first position and a second position with respect to the first siderail body about a rotational axis passing through the first siderail body. This can be realized by virtue of the fact that the body and the gate of the at least one evaluation transistor are connected to one another via a connection. The hollow body and nose portions define a biopsy cup for receiving a tissue sample therein and the opposing and linear edges form a pinching surface for contacting extremities of the tissue sample. The interposer includes a wiring having a plurality of branches for electrical connection between the terminal electrode for inputting a high power supply potential to the plurality of optical sensors and a wiring having a plurality of branches for electrical connection between the terminal electrode for inputting a low power supply potential to the plurality of optical sensors.
