Zusammenfassung: | The present invention intends to provide an inkjet printer capable of efficiently conducting the drying of a medium with reducing the leakage of electromagnetic waves. »/4 choke portions 112 through 118) are formed on introduction walls (128, 130) and the exit walls (132, 134). Each of choke lengths (120 through 126) of the »/4 choke portions (112 through 118) is »/4 relative to the wavelength » of electromagnetic waves. The incident waves entered into the »/4 choke portions (112, 114) from openings (113, 115) are reflected at walls of the »/4 choke portions (112, 114) after running the choke lengths (120, 122) of the »/4 choke portions (112, 114). The reflected waves are out of phase with the incident waves by »/2 so that the reflected waves and the incident waves attenuate each other, thereby preventing the electromagnetic waves from leaking out of the wave guide (100a) along the medium (50). |
