摘要： Tuning apparatus which is tunable to different broadcast frequencies and including a scale provided with indicia corresponding to such broadcast frequencies and a pointer movable across the scale to indicate the particular broadcast frequency to which the tuning apparatus is tuned. The pointer is supported by a movable support which is guided by a guide shaft. A plurality of markers are slidably guided along at least one guide rail and are individually settable to desired locations adjacent the scale, thereby representing particular broadcast frequencies to which the tuning apparatus is tunable. A key also is slidable along the guide shaft with the movable support, the key being selectively operative to engage a desired one of the markers to move the engaged marker therewith as the support is moved, whereby the marker is set to a desired position by reason of its engagement with the key. Tuning circuitry having a controllable oscillator for generating an oscillating signal whose frequency is variable and determinative of the broadcast frequency to which the tuning apparatus is tuned is enabled to produce an output representing received information when the movable support is moved to an aligned position with a respective one of the markers. Thus, the tuning apparatus can be rapidly tuned to any preset broadcast frequency as represented by the particular marker with which the pointer is aligned.
摘要翻译：调谐装置可调谐到不同的广播频率，并且包括提供有与这种广播频率相对应的标记的标度，以及可跨标尺移动的指针，以指示调谐装置调谐到的特定广播频率。指针由可由导向轴引导的可动支架支撑。多个标记沿着至少一个导轨被可滑动地引导，并且可以独立地设置到与标尺相邻的期望位置，从而表示调谐装置可调谐的特定广播频率。钥匙还可以沿着导向轴与可移动的支撑件滑动，该钥匙可选择性地操作以接合所需的一个标记，以随着支撑件的移动而使接合的标记物随之移动，由此，标记由于理由被设置到期望的位置与其密切相关。调谐电路具有可产生振荡信号的可控振荡器，该振荡信号的频率是可变的并且对调谐装置所调谐的广播频率作出决定，使得能够产生表示接收到的信息的输出，当可移动支撑件移动到相应位置时其中一个标记。因此，可以将调谐装置快速调谐到由指示器对准的特定标记所表示的任何预设广播频率。

摘要： A developing device has a developing unit to develop an electrostatic latent image formed on an image carrier surface with two-component developer composed of toner and carrier, a toner recycling device to feed toner removed from the image carrier surface by a cleaner back to the developing unit so as to recycle the removed toner, a supply member for supplying fresh toner to the developing device, and a toner concentration controller to control toner concentration in accordance with the result of a comparison between a reference signal that has been set, and a toner concentration of developer determined when the magnetic permeability of developer is detected by a toner concentration detection sensor disposed in the developing device. A drive source of the developing unit and that of the toner recycling device can be individually controlled. When a reference signal for the toner concentration sensor is to be set, a forcible idling operation is started in which the toner recycling device recycles toner to the developing device without the supply of fresh toner to the developing device by the supply member. Alternatively, the reference signal can be set when both the recycling device and supply member are inactive.
