MERCHANDISE SALES DATA PROCESSING DEVICE, MERCHANDISE SALES DATA PROCESSING SYSTEM, AND PROGRAM

To enable a merchandise sales data processing device to be improved in convenience.SOLUTION: The merchandise sales data processing device includes: registration means that can execute registration processing for a merchandise; adjustment means that can execute adjustment processing; transmission means that transmits registration data generated in the registration processing for causing another device to execute the adjustment processing; declaration means that declares execution of the adjustment processing in an own device; and control means that controls execution of the adjustment processing in the own device and execution of the adjustment processing in the other device. In the case where the declaration means has made a declaration, the control means allows the adjustment processing to be executed by the adjustment means irrespective of whether the other device is executing the adjustment processing.SELECTED DRAWING: Figure 18 【課題】商品販売データ処理装置の利便性を向上可能とする。【解決手段】商品の登録処理を実行可能な登録手段と、精算処理を実行可能な精算手段と、他装置で精算処理を実行させるために登録処理で生成された登録データを送信する送信手段と、自装置での精算処理の実行を宣言する宣言手段と、自装置での精算処理の実行と他装置での精算処理の実行とを制御する制御手段とを備え、制御手段は、宣言手段による宣言がある場合、他装置が精算処理中であるか否かに関わらず、精算手段による精算処理の実行を許可することを特徴とする。【選択図】図１８
