The power supply unit 222 is woken up.

その後、電源供給部２２２がウェークアップされ、制御部２１８と表示部２２０に電源が供給されることにより、電子価格標示器が動作するようになる。このように動作する光反応ウェークアップ部２２４の回路を、図４に例示的に図示する。   Thereafter, the power supply unit 222 is woken up, and power is supplied to the control unit 218 and the display unit 220, so that the electronic price indicator operates. The circuit of the photoreactive wakeup unit 224 operating in this way is exemplarily shown in FIG.

図４は、図３の光反応ウェークアップ部の回路図である。   FIG. 4 is a circuit diagram of the photoreactive wakeup unit in FIG.

図４を参照すると、光反応ウェークアップ部は、センサー薄膜トランジスタ（Ｓｅｎｓｏｒ ＴＦＴ）３００とキャパシタ３１０とからなる。   Referring to FIG. 4, the photoreactive wake-up unit includes a sensor thin film transistor (Sensor TFT) 300 and a capacitor 310.

センサー薄膜トランジスタ３００のソース端子は、基準電圧ＶＤＤに連結され、ゲートはオフされており、ドレイン端子は、キャパシタ３１０に連結されている。 The sensor thin film transistor 300 has a source terminal connected to the reference voltage V DD , a gate turned off, and a drain terminal connected to the capacitor 310.

そして、キャパシタ３１０は、センサー薄膜トランジスタ３００のゲートとドレイン端子との間に連結されている。   The capacitor 310 is connected between the gate and the drain terminal of the sensor thin film transistor 300.

このように構成された光反応ウェークアップ部のセンサー薄膜トランジスタ３００は、スキャナー光源から光が入射されると、入射された光量に応じる大きさの電流を出力する。   When the light from the scanner light source is incident, the sensor thin film transistor 300 of the photoreactive wakeup unit configured as described above outputs a current having a magnitude corresponding to the amount of incident light.

そして、キャパシタ３１０は、この電流に応じる電荷を蓄積し、これを電圧に変換して出力する。   Capacitor 310 accumulates electric charge corresponding to this current, converts it into a voltage, and outputs it.

このように、キャパシタ３１０がセンサー薄膜トランジスタ３００から出力される電流に応じるウェークアップ電圧を出力すると、これに連結された電源供給部３２０は、ウェークアップ電圧によって動作して、制御部と表示部に電圧を提供する。   As described above, when the capacitor 310 outputs a wakeup voltage corresponding to the current output from the sensor thin film transistor 300, the power supply unit 320 connected to the capacitor 310 operates according to the wakeup voltage and provides a voltage to the control unit and the display unit. To do.
