Abstract: A storage conveyor that secures a number of stored workpieces while saving space is provided. When a sprocket on a driving side is driven to rotate in a forward/reverse direction by a chain drive motor, opposing bend suppression members between a pair of chains are successively engaged/disengaged, and an opposing portion between the pair of chains is extended/retracted with respect to a workpiece conveyance surface. Thus, workpieces are passed between the workpiece conveyance surface and workpiece receivers. Consequently, the workpieces can be stored in a vertical direction (up-down direction), making it possible to secure the number of stored workpieces while saving space.

Abstract: Labelled item keys displayed on a touch sensitive display screen of a merchandise register (e.g., a POS terminal) are dynamically changed during operation of the register in accordance with a particular sale and/or previous sales. Information regarding all traded merchandise items is retained in a memory. Sales information relating to each merchandise item is updated and reorganized within the memory during the registration of each sale. After completion of each sales registration, merchandise items are ordered according to selected sales information associated with each merchandise item. In one example, a hierarchial ranking according to sales volume is created for all traded items. In addition, a key arrangement storing memory stores key arrangement data that specifies a particular positional arrangement or layout for displaying item identification indicia within a limited number of merchandise keys that are displayed on the touch sensitive display screen.

Abstract: An electronic cash register comprising a key input device having a plurality of operation keys, a file structured memory unit whose memory region is divided into a plurality of file storage regions for storing a plurality of different types of accumulated data, and a control unit for controlling the key input device and the memory unit. The control unit controls the memory unit so as to change the space allocation of a desired file storage region, generate a required file storage region, or erase a predetermined storage region.

Abstract: An electronic cash register includes thirty department keys for identifying the department of the commodity purchased by the customer. A department memory has ninety memory sections each of which stores the unit cost information and the total amount of the transaction related to the commodity of a specific department. Three department level keys are provided to divide the department memory into three groups. When the first department level key is selected, the thirty department keys correspond to the first through thirtieth memory sections in the department memory. When the second department level key is selected, the thirty department keys correspond to thirty-first through sixtieth memory sections. When the third department level key is selected, the sixty-first through ninetieth memory sections correspond to the thirty department keys.

Abstract: An electronic cash register comprising a volatile memory for the storage of data concerned with cash registration, a writable non-volatile memory for the storage of the data, and a control for writing the data in the non-volatile memory. The contents stored in the volatile memory can be corrected, if necessary, on the basis of the data stored in the non-volatile memory.

Abstract: Serration rolling tools and thread rolling tools each having groups of leading teeth, finishing teeth and disengaging teeth are provided, a lead angle of the thread rolling tool being set in accordance with the rolling diameter of the serration section in a work piece. The thread rolling tool and serration rolling tool are arranged parallel and integrally. First a rolling operation for forming serrations is started by the serration rolling tools, a rolling operation for forming threads being started by the thread rolling tools in the course of the rolling operation by the group of the leading teeth of the serration rolling tools. A rolling operation for finishing the threads is completed in the latter half of the rolling operation by the group of the finishing teeth for the serrations. The difference in rolling diameters is absorbed by the slide of the aforesaid thread rolling tools on a shaft member (work piece), thus enabling the simultaneous formation of serrations and threads in a short rolling stroke.

Abstract: A coin dispenser is disclosed which includes a plurality of containers at least two of which contain coins of a same kind. A pattern generator develops container selection signals in accordance with coin dispensation amount information applied thereto. A control system is connected to receive the container selection signals and functions to select one of the at least two containers containing the same kind of coins alternatingly or sequentially, thereby uniformly dispensing coins from the at least two containers.
