Consequently, the sound wave, which is similar to the output voltage waveform of the alternating current power source 10 and of which phase is reversed, is output from the speaker 8 arranged in a parts feeder main frame. At this stage, the sound pressure level of the speaker 8 is set nearly equal to the sound pressure level of the noise from a bowl 2 corresponding to the drive of the oscillation generating means 5 to offset each other. With this structure, the noise can be reduced without enlargement of a device and lowering of the function.

Title: Method for deciding threshold value
Inventor: YAMAJI SATORU
IPC: G06T1/00
Filed: 1991-02-26
Abstract: PURPOSE:To enable satisfactory binarization which corresponds to picture density distribution, by obtaining the density range of a background with the most frequent value of a density histogram as reference so as to adopt the upper limit of the density range of the background as a threshold value. CONSTITUTION:A peak where a background part and an information part respectively make a nearly normal distribution is formed and the most frequent value of the background part is higher than that of the information part. Here, it is considered that the part with a density being thinner than the density m which gives the most frequent value of the background part correctly reflects the density distribution with only the background. In fact, the part with the density being thicker than m often becomes the superimposition of the information part. Then, the symmetric distribution obtained by inverting the distribution in the part with density being thinner than m with m as a center is generated (oblique lines). The area of a certain range in the distribution is regarded as the background and 2m, its upper limit, comes to be a threshold value. The area regarded as the background here is generally evaluation with a standard deviation as reference. The range is decided by considering an error in the density range of the background, which is estimated from the histogram.
