Abstract: Smooth transaction at an ECR is facilitated. An ECR includes a customer number counter and a lamp which are connected to each other by a signal line hence which are controllable by a CPU. In a RAM of the ECR, memories and a total customer number memory are disposed. In the memory, a predetermined value which serves as a reference for judging the crowdedness of the ECR is set. A difference between a value which is obtained at the memory by adding up and storing the sum of the numbers of customers waiting in front of the ECR which are read from the customer number counter and a value which is obtained at the total customer number memory in which values obtained at the memory which stores the number of customers for one transaction are serially added up and stored is compared with a value which is obtained at the memory. If the difference is smaller than the value at the memory, the CPU determines that the ECR is not crowded and turns on the lamp.

Abstract: A data transmission device includes a memory for storing a plurality of data consisting of a plurality of sorting areas. The device selectively transmits the data of the sorting area including a desired data in response to a predetermined command signal. Data of the sorting areas including data not desired may not be sent. A central processing unit is connected to each of the electronic cash registers through one or more communication lines and when the electronic cash register receives a command signal sent from the central processing unit, the electronic cash register acts according to the command signal to send specific data.

Abstract: A data processing device consists of a first memory and a plurality of second memories. When transferring data to the first memory from the plurality of second memories having transfer orders of the data predetermined with respect to each other, the data can be maintained in each of the second memories until the transfer of all the data stored in the second memories is completed. Therefore, even in the case where the data stored in the second memories cannot be correctly transferred to the first memory due to an occurrence of an error, the data maintained in the second memories can be saved.

Abstract: A print control system in a banking machine performs a validation printing, wherein the printing operation of the same printing data is repeatedly conducted by shifting the record receiving paper sheet in the direction along the printing line after the completion of the one line data printing. The print control system includes a paper feeding mechanism which tightly holds the record receiving paper sheet while the actual printing operation is conducted, and shifts the record receiving paper sheet along the printing line by a predetermined distance after the completion of the actual printing operation.

Abstract: A serial impact printer has two printing modes, one being a formed-character mode and the other a dot matrix mode. A plurality of dot matrix wires are disposed behind a character carrying member having characters on fingers. One of the wires impacts a selected finger in the formed-character mode. In the dot matrix mode, however, printing is performed by directly contacting a paper with selected ones of said dot matrix wires.
