In the unit chair for the dental treatment, the microscope 300 is mounted on the upper surface of the control table 200, so that a doctor can capture bacteria inside the patient's buccal cavity through the microscope 300. The microscope 300 includes the CCD module 310 having a lens part located on a glass plate, an LED for emitting back light under the glass plate, and user key input means for manipulation of the microscope. Furthermore, the oral camera 400 includes the CCD module 410 for capturing the intra buccal cavity, lighting means (LED) , and user key input means for manipulation of the camera. The oral camera 400 may be mounted on the tool holder 210 for holding various tools (handpieces) such as a cutting tool for the medical treatment, or may be fixed on a mounting part positioned at another place excepting the tool holder 210 . The control table 200 has the control device therein for controlling the height of the chair and activation of the tools such as the cutting tool for the dental treatment. The camera image-processing device 500 for receiving and processing the signals outputted from the CCD modules 310 and 410 of the microscope 300 and the oral camera 400 and displaying the signals on the monitor 600 is embedded in the control table 200. The camera image-processing device 500 may be in the form of a board or a module. The power supply for supplying electric power from the .commercial power source of AC 220V is embedded in the control table 200. The camera image-processing device 500 may receive electric power from the power supply disposed inside the control table 200 or, like this embodiment, may have a power supply 560 therein for using electric power. The control table 200 is designed in such a way that the data cables for receiving data captured from the CCD module 310 of the microscope 300 and the CCD module 410 of the oral camera 400 are connected from their own positions to the camera image-processing device 500 mounted inside i the control table 200.

The communication port 551 comes up to a standard of the communication interface part 550 of the camera image- processing device 500, and may consist of a serial communication RS232C or a USB communication interface. Of course, both of the serial communication and USB communication interface must have a communication standard applicable to the monitor 600. The operation process of the intra buccal cavity examination system of the unit chair will be described as follows . The doctor selects the image switch 700 disposed on the control table 200 so as to display the image captured by the oral camera 400 or the microscope 500 on the monitor 600. When the doctor selects the image switch 700, the switching control part 510 selects and outputs the image signal captured by the CCD module 410 of the oral camera 400 or the CCD module 310 of the microscope 300. The signal outputted from the switching control part 510 is converted into the digitally processable signal through the preprocessing part 520 and outputted to the DSP 530. The digital signal processing part 530 processes the image signal inputted through the preprocessing part 520 into the digital signal and converts and outputs the digital signal into the signal which is displayable on the monitor 600. The communication interface part 550 outputs the image signal inputted from the digital signal processing part 530 to the monitor 600 connected to the communication port 551 to display the image. At this time, the image may be a still image or a moving picture image according to the doctor' s manipulation of the user key input means of the oral camera 400 or the microscope 300. In another embodiment of the present invention, the communication interface part 550 of the camera image- processing device 500' is connected to a PC so that the image is displayed on a PC monitor, and the image can be stored in and outputted from the PC. Additionally, the communication interface part 500 may have one or more communication ports 551 so as to allow both of the monitor 600 and the PC to output the image, so that the doctor can consult and treat using the monitor 600 and store and output the image using the PC.
