Zusammenfassung:	PROBLEM TO BE SOLVED: To return an error of reservation information to a previous state through easier operation.SOLUTION: A facility reservation device comprises a computation unit and a storage unit. The storage unit includes a data area and a stack area. The computation unit generates reservation information showing a first reservation state in the data area and when generating reservation information showing a second reservation state in the data area, saves the information showing the first reservation state in the stack area and when acquiring an instruction for return to the reservation information showing the first reservation state, reads out the information showing the first reservation state in the data area from the stack area and then creates reservation information showing the completion of the return and also showing the first reservation state.SELECTED DRAWING: Figure 2 【課題】予約情報の誤りを、より簡単な操作によって誤りが生じる前の状態に戻すことができる。【解決手段】演算部と記憶部とを備え、前記記憶部は、データ領域およびスタック領域を有し、前記演算部は、第１の予約状態を示す予約情報を前記データ領域に生成し、第２の予約状態を示す予約情報を前記データ領域に生成する際、前記第１の予約状態を示す情報を前記スタック領域に退避し、前記第１の予約状態を示す予約情報への差戻し指示を取得すると、前記スタック領域から前記データ領域に前記第１の予約状態を示す情報を読み出し、差戻されたことを示すと共に前記第１の予約状態を示す予約情報を生成する。【選択図】図２
