    • An input apparatus (for example, a mobile terminal apparatus (100)) includes a display unit (60) that displays a plurality of operation position displays (for example, operation position displays (61 to 66)); and a detection unit that contactlessly detects an operation which corresponds to an operation position set in a specific space of a front of the input apparatus in correspondence to each of the plurality of operation position displays. The detection unit includes a first piezoelectric element (an oscillation piezoelectric element (31)) that oscillates ultrasound toward the front space of the input apparatus; a second piezoelectric element (a reception piezoelectric element (21)) that detects the ultrasound which is oscillated by the first piezoelectric element; and a determination unit that determines whether or not an operation is performed on a certain operation position based on a result of detection performed by the second piezoelectric element.
    • 输入装置(例如,移动终端装置)具备显示多个操作位置显示(例如,操作位置显示(61〜66))的显示部(60)。 以及检测单元,其对应于所述多个操作位置显示中的每一个,对与输入装置的前部的特定空间中设置的操作位置相对应的操作进行无接触地检测。 检测单元包括使超声波朝向输入设备的前部空间振荡的第一压电元件(振荡压电元件(31)); 第二压电元件(接收压电元件),其检测由所述第一压电元件振荡的超声波; 以及确定单元,其基于由所述第二压电元件执行的检测结果来确定是否在某个操作位置执行操作。

    • An oscillator creates a reference voltage based on a pulse signal corresponding to an oscillation output of a crystal oscillation circuit and controls a supply voltage to the crystal oscillation circuit according to the reference voltage. A control signal creating circuit creates a control signal based on the pulse signal and reference voltage generating circuits that control the reference voltage based on the control signal. The control signal creating circuit creates a low-level control signal when the pulse signal is in a low level, creates a high-level control signal when the pulse signal is in a high level, and prevents transition of the control signal from the high level to the low level.
    • 振荡器基于与晶体振荡电路的振荡输出对应的脉冲信号产生参考电压,并根据参考电压控制到晶体振荡电路的电源电压。 控制信号生成电路基于脉冲信号和基于控制信号控制参考电压的参考电压产生电路产生控制信号。 当脉冲信号为低电平时,控制信号产生电路产生低电平控制信号,当脉冲信号处于高电平时产生高电平控制信号,并且防止控制信号从高电平 到低水平。
