A movable terminal and a coaxial connector have greatly improved durability and have outstanding contactconnection reliability, and are included in a communication apparatus. The frame allows individual implements to be positioned generally transversely in an operating position for travel in a first direction providing maximum operating width, and generally longitudinally in a transport position for travel in a direction opposite to the first direction in which the overall with of the implements on the frame is minimized to three meters or less. In one embodiment, a finite conjugate lens system is disclosed. The combination of the two provide unmistakable visual indicia that will help limit or reduce wrong site medical procedures. The substrate includes a first surface, a second surface on an opposite side of the first surface, and an applied part on which the light emitting element is mounted.
