Title: Merchandise sales control system
Claims: What is claimed is: 1. A merchandise sales control system comprising a plurality of memory cassettes each having at least a recording section composed of a unit-price setting section and a sales data section, a unit-price writing device able to removably connect to said memory cassettes and to preset a number of commodity unit prices in the unit-price setting section of each of said memory cassettes, a plurality of electronic cash registers able to removably connect to said memory cassettes, and a totalling device able to removably connect to said memory cassettes, wherein said memory cassettes are connected to said unit-price writing device which presets a number of commodity unit prices in the unit-price setting section of said memory cassettes, then the memory cassettes are connected to said electronic cash registers respectively to perform sales registration so that sales data based on the commodity unit prices stored in said unit-price setting section are registered in said sales data section, and then said memory cassettes in which the sales data are registered are removed from said electronic cash registers and are connected to said totalling device which totals the sales data stored in said electronic cash registers. 2. The system as set forth in claim 1, wherein said unit-price writing device and said totalling device are formed independently of each other. 3. The system as set forth in claim 1, wherein said electronic cash register contains therein a unit-price setting memory so that unit-price setting data other than those stored in said memory cassettes may be stored therein to perform registration. 4. The system as set forth in claim 1, wherein totalled data are stored in at least one of a plurality of said memory cassettes to be mounted on said totalling device. 5. The system as set forth in claim 1, wherein said unit-price setting section and sales data section are provided in said memory cassette along the digits of each address. 6. The system as set forth in claim 1, wherein said unit-price writing device and totalling device are incorporated into a unit-price-writing and sales-totalling device. 7. The system as set forth in claim 6, comprising numeral keys for inputting numerical data, commodity keys for designating the classification code of a particular commodity, a CPU, memories for unit-price setting program and totalling program, said memories being selectively connected to said CPU, a control device for selecting and starting said programs, a plurality of memory cassettes removably connected to said CPU and having a recording section composed of a commodity unit-price setting section and a sales data section, and a total memory connected to said CPU and in which the totals of the sales data of said memory cassettes are stored. 8. A merchandise sales control system comprising a plurality of electronic cash registers, memory cassettes each removably mounted on each of said electronic cash registers and capable of storing sales data, and a totalling device for totalling sales data, wherein said memory cassettes, which are made to store sales data by the registration operation of said electronic cash registers, are simultaneously set in said totalling device so as to obtain total values such as gross sales total, cash sale total and the like necessary for merchandise control. 9. A merchandise sales control system comprising a plurality of memory cassettes each having at least a recording section composed of a unit-price setting section and a sales data section, a unit-price writing device able to removably connect to said memory cassettes and to preset a number of commodity unit prices in the unit-price setting section of each of said memory cassettes, a plurality of memoryless electronic cash registers able to removably connect to said memory cassettes, and a totalling device able to removably connect to said memory cassettes, wherein said memory cassettes are connected to said unit-price writing device which presets a number of commodity unit prices in the unit-price setting section of said memory cassettes, then the memory cassettes are connected to said electronic cash registers respectively to perform sales registration so that sales data based on the commodity unit prices stored in said unit-price setting section are registered in said sales data section, and then said memory cassettes in which the sales data are registered are removed from said electronic cash registers and are connected to said totalling device which totals the sales data stored in said electronic cash registers. 10. A merchandise sales control system comprising a plurality of memory cassettes each having at least a recording section composed of a unit-price setting section and a sales data section, a unit-price writing device able to removably connect to said memory cassettes to preset only newly changed commodity unit prices in the unit-price setting section of each of said memory cassettes, a plurality of electronic cash registers able to removably connect to said memory cassettes, and a totalling device able to removably connect to said memory cassettes, wherein said memory cassettes are connected to said unit-price writing device which presets a number of newly changed commodity unit prices in the unit-price setting section of said memory cassettes, then the memory cassettes are connected to said electronic cash registers respectively to perform sales registration so that sales data based on the commodity unit prices stored in said unit-price setting section are registered in said sales data section, and then said memory cassettes in which the sales data are registered are removed from said electronic cash registers and are connected to said totalling device which totals the sales data stored in said electronic cash registers.
