An inkjet head system has an inkjet head and a printed board connected to the inkjet head. In this semiconductor laser device, a receivingemitting optics integrated substrate, in which two semiconductor laser elements with different emission wavelengths and a plurality of receiving optics are integrated, is disposed in a case and is sealed with a hologram element. Conductor lines for supplying an electrical voltage for electrochemically etching the diaphragms are formed on and along the interstices. In the first preset condition, the bias controller produces a first engagement force on the portion of the filler wire that is located between the wire contacting portions of the idler roll and the driver roll. The propellant is arranged within the product chamber to pressurize the texture material.
