Abstract: The present invention relates to an apparatus for generating quasi equally spaced multi-channel frequencies using a frequency shifter. The optical multi-channel transmission system using OFDM or WDM can be provided with quasi equally spaced(unequally sequential spaced) frequencies on the basis of the functional relation among the frequency differences(n.sub.ij =n.sub.i -n.sub.j (i=j=1,2,3, . . . n)) of any two neighboring channels. Namely, after generating equally spaced frequencies by using a reference resonator, such as a Fiber Fabry Perot(FFP) resonator, each of the equally spaced frequencies is sequentially shifted by a frequency shifter, which generates and controls the quasi equally spaced(unequally sequential spaced) frequencies in order to effectively avoid crosstalk due to FFWM, and fully make use of the transmission bandwidth belonging to the low dispersion region of the optical fiber. the effect of the present invention will be apparent as follows: by easily generating and controlling quasi equally spaced frequencies having a functional relation between two adjacent channels, crosstalk due to Fiber Four Wave Mixing(FFWM) is effectively avoided, and the transmission bandwidth in the region of the low dispersion is fully utilized. Furthermore, the compatibility is easily accomplished.

Abstract translation: 本发明涉及一种使用移频器产生准等距多声道频率的装置。 基于频差之间的功能关系，可以使用OFDM或WDM的光多通道传输系统提供准等间隔（不等间隔的）频率（nij = ni-nj（i = j = 1,2， 3，...，n））。 也就是说，在通过使用参考谐振器（例如光纤法布里珀罗（FFP））谐振器产生等间隔的频率之后，每个等间隔的频率被移频器顺序移位，该移频器产生并控制准等距间隔（不等间隔的 ）频率，以便有效地避免由于FFWM引起的串扰，并充分利用属于光纤低色散区域的传输带宽。 本发明的效果将显而易见：通过容易地产生和控制具有两个相邻通道之间的功能关系的准等间隔的频率，有效地避免了由于光纤四波混频（FFWM）引起的串扰，并且传输带宽 低分散的区域被充分利用。 此外，容易实现兼容性。

Abstract: The present invention provides a developing device of an electrophotographic recording system for developing an electrostatic latent image formed on a photosensitive drum. The developing device includes a hopper which stores toner and a developing roller which develops the electrostatic latent image formed on the photosensitive drum using the toner stored in the hopper. On one side of the hopper at a predetermined height from its bottom, a light-emitting element for emitting light is positioned. A toner detecting device detects the existence or non-existence of toner by using a light-receiving element positioned on the interior of the hopper which outputs signals corresponding to the existence or non-existence of toner in the hopper in response to the amount of the light received from the light-emitting element. An agitator conveys the toner to the developing roller and simultaneously cleans a light-emitting side of the light-emitting element and a light-receiving side of the light-receiving element in synchronism with a conveyance period of the toner. A signal transmitting device transmits signals from the light-receiving element to a CPU which compares the number of signals with a predetermined value, thereby determining a level of the toner.
