Commodity sales data processor

Abstract

Connection of a USB memory (storage device) to a USB port (data transmitting and receiving unit) is detected and the date and time of detection of this connection is stored. Using this detection of connection as trigger, a camera is caused to pick up an image of an area embracing a user positioned in a position where the user can operate a user interface. Picked-up image data outputted from the camera is stored together with shooting date and time.

1 . A commodity sales data processor, comprising:
 a user interface having an information input function;   a display unit having an information display function;   a camera picking up an image of an area embracing a user in a position where the user can operate the user interface and outputting picked-up image data;   a data transmitting and receiving unit allowing a storage device that rewritably stores data to be connected thereto and enabling data communication with the storage device; and   an information processing unit which executes:
 detecting connection of the storage device to the data transmitting and receiving unit; 
 storing, after the connection is detected, the picked-up image data output from the camera and shooting date and time together in a storage area; 
 displaying a picked-up image based on the picked-up image data stored in the storage area in an area of the display unit for displaying information related to execution of commodity sales data processing; and 
 controlling access to data in the storage area. 
   
     
     
         2 . The commodity sales data processor of  claim 1 , wherein the information processing unit is configured to display the picked-up image based on the picked-up image data stored in the storage area with predetermined warning characters as a warning display in the area for displaying the information related to the execution of commodity sales data processing. 
     
     
         3 . The commodity sales data processor of  claim 1 , wherein the information processing unit is configured to display the shooting date and time of the picked-up image data stored in the storage area with the picked-up image based on the picked-up image data in the area for displaying the information related to the execution of commodity sales data processing. 
     
     
         4 . The commodity sales data processor of  claim 1 , wherein
 the data transmitting and receiving unit is a USB port, wherein the storage device is a universal serial bus (USB) port,   the storage area is in a hard disk drive, and   the camera is disposed in such a position that an image of an area embracing a user in a position where the user can operate the USB port can be picked up.
