Problems solved by technology

[0006] However, when the coupling capacitance is reduced according to the physical size or position of the electrostatic coupling surface in this way, the change in the area or interval of the electrostatic coupling surface excessively affects the signal transmission characteristics, and it is impossible to tolerate the occurrence of the problem caused by manufacturing tolerances or movement between the electrostatic coupling surfaces. deviation

Abstract

A signal transmission device includes a transmission unit, a first connection unit, a second connection unit, and a reception unit. The transmission unit sends a transmission signal. The first connection unit includes a first electrode electrically connected to the transmission unit. The second connection unit includes a second electrode that engages with the first connection unit, and, when engaged with the first connection unit, is statically coupled with the first electrode. The reception unit is electrically connected to the second electrode and receives the transmission signal.

Description

technical field [0001] The present invention relates to a signal transmission device and an endoscope system with the signal transmission device. [0002] This application claims priority based on Japanese Patent Application No. 2009-178247 for which it applied in Japan on July 30, 2009, and uses the content here. Background technique [0003] In order to transmit signals in a contactless manner, for example, as disclosed in Patent Document 1, an electrostatic coupling method utilizing electrostatic coupling by a pair of elements is employed. [0004] Here, in the case of AC (alternating current) coupling between the transmitting unit and the receiving unit as in the electrostatic coupling method, the “H ” (or “1”) signal and “L” (or “0”) signal, which represent the intensity level of each signal of the transmitted signal, and sometimes use these “H” signals and “L” signals in equal numbers to each other Manchester Yards. [0005] In this electrostatic coupling method, in...
