An infrared sensor is provided with a thermopile formed with a plurality of thermocouples connected to each other. A structure having a periphery is reproduced by an objective and an electronic representation of the structure reproduced by the objective is generated. The earthing lines are set between the first conductive wire area and the second conductive wire area. In normal mode, fans circulate air to maintain a relatively uniform temperature throughout the chamber. The device provides for articulating motion as well as actuation that may be used in grasping, cutting, suturing or the like. While the panel rotates to disengage the fixing rod from the fixing hole, the storage element can be separated from the cabinet.
