Patent attributes
In one embodiment, a commodity sales data processing apparatus includes a portable data processing terminal with a first connector and a touch panel. A docking station has a second connector which connects to the first connector and performs transmission and/or reception of information between the data processing terminal and the docking station, when the data processing terminal is connected to the docking station. A connection mechanism connects the data processing terminal and the docking station in a separable state. A lock mechanism locks connection by the connection mechanism, so as to make the connection by the connection mechanism from in the separable state to in an inseparable state, and releases locking of the connection by the connection mechanism when a specific key operation is performed.
