Commodity sales data processing apparatus and method for taking over processing by the same

Abstract

In accordance with one embodiment, a commodity sales data processing apparatus comprises a stationary type docking station with a storage module, and a portable information terminal which is attached to and detached from the docking station freely. The information terminal receives an input of data relating to the sales of a commodity to process the received data, and stores the data required to take over the processing in the storage module of the docking station Then the information terminal successively executes, if the information terminal is attached to the docking station, the processing by referring to the data stored in the storage module of the docking station.

What is claimed is: 
     
         1 . A commodity sales data processing apparatus, comprising:
 a stationary type docking station having a storage module; and   a portable information terminal configured to be attached to and detached from the docking station freely; wherein   the information terminal includes:   an input module configured to receive an input of data relating to the sales of a commodity,   a processing module configured to process the data received by the input module,   a first control module configured to store data required to take over the processing of the processing module in the storage module of the docking station, and   a second control module configured to enable, if the information terminal is attached to the docking station, the processing module to successively execute the processing by referring to the data stored in the storage module of the docking station.   
     
     
         2 . The commodity sales data processing apparatus according to  claim 1 , wherein
 the first control module sequentially stores the data required to take over the processing in the storage module of the docking station as the processing module executes the processing.   
     
     
         3 . The commodity sales data processing apparatus according to  claim 1 , wherein
 the first control module stops, when receiving a processing takeover designation, the processing being executed by the processing module and stores the data required to restart the stopped processing in the storage module of the docking station.   
     
     
         4 . The commodity sales data processing apparatus according to  claim 1 , wherein
 the information terminal further includes a display control module configured to display, in a case of continuously executing the processing, the data indicating the information terminal executing the processing previously.   
     
     
         5 . An information terminal that is attached to and detached from a docking station having a storage module freely, comprising:
 an input module configured to receive an input of data relating to the sales of a commodity;   a processing module configured to process the data received by the input module;   a first control module configured to store the data required to take over the processing of the processing module in the storage module of the docking station; and   a second control module configured to enable, if the information terminal is attached to the docking station, the processing module to successively execute the processing by referring to the data stored in the storage module of the docking station.   
     
     
         6 . A method for taking over processing by an information terminal attached to a docking station with a storage module, including:
 an input of data relating to the sales of a commodity;   processing the received data;   storing the data required to take over the processing in the storage module of the docking station; and   successively executing, if the information terminal is attached to the docking station, the processing by referring to the data stored in the storage module of the docking station.
