Image processing device with operation panel responding by vibration

An image processing device comprising:

• an image processing unit configured to capture an image from a sheet and/or print an image on a sheet;
• a housing supporting the image processing unit inside itself;
• and
• an operation panel mounted on the housing and configured to display an operation screen for the image processing unit to accept user operation on the operation screen, the operation panel including:
• a touch panel having a display region for the operation screen and configured to sense an outer object touching the display region;
• a vibrator unit configured to apply vibration to the display region;
• and
• a response controller unit configured to, in response to the touch panel sensing the object, instruct the vibrator unit to apply to the display region vibration responsive to the object, the response controller unit also configured to check whether the image processing unit is under waiting or operating condition at the time the touch panel senses the object, and when the image processing unit is under the operating condition, set the responsive vibration to a level lower than when the image processing unit is under the waiting condition.
