  • Electronic cash register mutual transmission system for plurality of cash registers
    Patent number: 4398250
    Abstract: In an electronic cash register mutual transmission system, a plurality of electronic cash registers each having a memory for storing total data are electrically connected to each other. A search is made to confirm whether the classified sales data storage area is present in the memory of an electronic cash register which corresponds to the classified data inputted from another of the electronic cash registers. If it is present, the summing is performed in the memory of the former electronic cash register. If it is absent, the classification data is transmitted to another electronic cash register. The former electronic cash register outputs a request signal for data transfer to other electronic cash registers. In response to this request signal, the other electronic cash registers transfer the total data for printing by the former electronic cash register.

  • Calculator having integrating function
    Patent number: 4398263
    Abstract: A calculator having an integration function has at least a key input section which in turn has registering keys for inputting data for setting a function to be integrated and an interval of integration, and executing keys for performing the definite integrating function. The function to be integrated is stored in a predetermined register of a RAM by key operation on the key input section. A dividing number for dividing the interval of integration input by the key operation is stored in another register. The interval of integration is divided by the dividing number stored in the latter register. The integrating function is performed sequentially based on the function to be integrated every interval of integration divided by a dividing means and the data input by the key operation for setting the interval of integration.

  • Electronic cash register
    Patent number: 4389707
    Abstract: An electronic cash register has first and second total memories for storing data of accumulated sales amounts, and which is capable of two different types of settlement operations. It checks whether the first total memory has been reset before commencing the operation of resetting the second total memory, and resets the second total memory if the first total memory has been reset. A flag memory is provided for storing flag data such that when no flag data is stored in the flag memory upon actuation of the second settlement designation key, the total sales data in the first total memory is cumulatively stored in the corresponding memory areas of the second total memory and thereafter the data in the second total memory is supplied to the printing means.
