A further known electronic cash register with a data reading wand is disclosed in US-A-3 916 386. The data reading wand is designed for reading data tags or badges. The security of this known cash register is not very high, since the message strip manager's badge or clerk's badge is easily forged, since the magnetic strips are detachably adhered to the badges or goods. This cash register is intended to input information easily with respect to point-of-sale or the like.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an electronic cash register having a large number of operating modes each assigned to respective operators so that the operating modes can be implemented easily and at low costs. Further, the cash register of the present invention should obtain a high security level.
The object of the present invention can be achieved by a cash register having a plurality of operating modes to be switched among by an operator, comprising a cash register main body including means for specifying one or more kinds of said operating modes, means for determining whether said operating mode specified by said specifying means is permitted to said operator, and means for executing a process of cash registering corresponding to said specified operating mode at a time when said specified operating mode is determined to be permitted to said operator by said determining means,
   characterized in that said cash register comprises a memory card to be possessed by an operator for storing one or more operating modes therein as a permitted operating range, and in that said cash register main body includes a connector for receiving said inserted memory card and means for reading said operating range from said memory card through said connector, and that said determining means determines that said specified operating mode is permitted to said operator when said specified operating mode is determined to be within said operating ranges read by said reading means from said memory card.
In operation, when the specifying unit serves to specify the operation mode, the reading unit is initiated to read the operating range from the memory card. Then, the determining unit serves to determine whether or not the operating mode specified by the specifying unit is included in the operating range read by the reading unit.

    The alarming unit 17 may be any light or sound indicator such as a buzzer or a lamp.
    Fig.2 is a block diagram showing an arrangement of a second embodiment of a cash register according to the present invention.
    The cash register shown in Fig.2 is a point-of-sales electronic cash register (hereinafter, referred as POS.ECR).
    As shown in Fig. 2, a memory card 20 is provided with a main body 21 of POS.ECR which includes a connector 22 for receiving the memory card 20. Aside from the connector 22, the main body 21 of the POS.ECR further includes an input/output (I/O) buffer 23 connected to the connector 22, a keyboard 24, a key interface 25 connected to the keyboard 24, a central processing unit (CPU) 26 connected to both of the I/O buffer 23 and the key interface 25, a read only memory (ROM) 27 connected to both of the I/O buffer 23 and the key interface 25, and a random access memory (RAM) 28 connected to both of the I/O buffer 23 and the key interface 25.
    The memory card 20 has an integrated circuit (IC) memory built therein and also has a kind of operating mode written as its operating range. The operating mode is selected from various modes such as a setting mode, a registering mode, a checking mode, and a clearing mode.
    The main body 21 of the POS.ECR has the connector 22 to which the memory card 20 is inserted.
    The keyboard 24 is provided in the main body 21. The keyboard 24 provides keys (not shown) for various operating modes such as a setting mode, a registering mode, a checking mode, and a clearing mode.
    The key interface 25 serves to send a key scan signal to the keyboard 24 and to receive a return signal therefrom.

    Next, the description will be directed to the operation of the CPU 26 of Fig.2 referring to the flowchart shown in Fig.4.
    In case that the operation is executed at a certain mode, an operator presses a key for the mode on the keyboard 24.
    When the proper key on the keyboard 24 is pressed (step S1), the CPU 26 reads the operating range flag stored in a predetermined area of the memory card 20 (step S2) and determines whether or not the operation specified by the key is enabled, that is, whether the operating range flag is 1 or not (step S3). If it is 1, the specified operation is enabled. The later process is executed at the mode (step S4). If it is not 1, the specified operation is disabled. Then, the operation error is indicated (step S5).
    As set forth above, the embodiment of the present invention is arranged to prepare one kind of memory card 20 even if two or more persons may use the cash register.
    By writing some factors such as an operating range flag, a user code, and a transaction limit card in a predetermined area of the memory card 20, it is possible to properly manage the cash register for a point of sale without using the key switches.
    Many widely different embodiments of the present invention may be constructed and the present invention is not limited to the specific embodiments described in the specification, except as defined in the appended claims.
