This invention provides a micro controller in which a JTAG port becomes available through a specific operation even after a security bit is set. To guide and hold the lens folding cartridge a cylindrical opening is provided which encloses the back portion of the injecting nozzle. Subsequent times are measured with respect to this time reference by using the internal clock to measure time intervals therefrom. In a further embodiment, the above-described embodiments of the present invention are implemented in a computer-readable medium where the report, information, analysis system are executed by a processor. The pivot and the contact surface are both made of resin, and the contact surface is made of a resin having a higher hardness than the pivot.
