<p>Title of InventionDRIVING DEVICE AND SPATIAL INFORMATION DETECTING DEVICE USING 5 THE SAMEThe driving device includes an applied voltage control unit configured to perform a transfer process of controlling a charge-coupled device to transfer electric charges. The applied voltage control unit is configured to switch, in order from a first end to a10 second end of a line of transfer electrodes of the charge-coupled device, a voltage applied to the transfer electrode from a control voltage for forming a potential well to a reference voltage for eliminating the potential well. The applied voltage control unit includes a control circuit configured to generate a driving signal based on a clock signal, and a driving circuit configured to apply the control voltage and the reference15 voltage selectively to the transfer electrode in accordance with the driving signal. The control circuit is configured to delay a second driving signal defined by thedriving signal associated with one of the adjacent transfer electrodes from a first driving signal defined by the driving signal associated with the other of the adjacent transfer electrodes so as to adjust a phase difference between the first driving signal20 and the second driving signal to a value corresponding to predetermined time shorter than a period of the clock signal.(Figure 1)</p> |
