    • First, in a state where a pair of earphones 110 are worn in both ears of a listening person, a measurement signal generated by a measurement signal generating section 101 is outputted from the earphone 110. The signal (wearing-state signal) which is reflected by an eardrum and returns to the earphone 110 is measured, and stored in an analysis section 108. Next, in a state where the pair of earphones 110 are not worn in both ears of the listening person, a signal measured (unwearing-state signal) in the same manner as described above is stored in the analysis section 108. The analysis section 108 calculates an ear-canal correction filter based on a difference between the wearing-state signal and the unwearing-state signal. An ear-canal correction filter processing section 109 convolves a sound source signal with the calculated ear-canal correction filter.
    • 首先,在听筒的双耳中佩戴一对耳机110的状态下,从耳机110输出由测量信号生成部101生成的测量信号。被反射的信号(磨损状态信号) 通过耳膜测量并返回到耳机110,并将其存储在分析部分108中。接下来,在听筒的两只耳朵中未佩戴一对耳机110的状态下,测量信号(非打开状态信号 )以分析部分108存储。分析部分108基于磨损状态信号和非打开状态信号之间的差异来计算耳道校正滤波器。 耳道校正滤波器处理部分109将声源信号与计算出的耳道校正滤波器进行卷积。

    • An automatic document feeder is provided with a reading unit disposed above a platen for reading an original. The reading unit includes a platen roller for transporting the original to the reading unit; a guide device arranged between the platen and the platen roller and formed in a curved original reading path; a pressing device for pressing the guide device against the platen roller; and a regulating device for creating a space between a surface of the platen roller and an upper surface of the platen. When the original is transported between the platen roller and the guide device, the original moves the guide device toward the platen.
