ABSTRACT OF THE DISCLOSURE To allow a saleman to record data relating to merchandise items which are to be ordered, a logging device comprises a casing in which are housed a keyboard, a display and associated circuits. The salesman locates a sheet containing a list of merchandise items, on the casing beween two columns of light emitting diodes. At the start of entry of an order, the top left-hand LED is illuminated under the control of a central processor unit which simultaneously addresses a main memory storage location corresponding to the item alongside that LED. Data, such as quantity required, can then be keyed into that storage location, which already contains an identification code for that item. The salesman then operates a key which causes the CPU to scan through the LEDs, and the storage locations, in turn, until the next required item on the sheet is reached. Data relating to that item is then keyed-in. At the end of each day, the salesman couples a transducer to a public telephone and transmits the data to a computer at his base. Due to the automatic correspondence, at any instant, between the item indicated by an LED and the respective storage locattion containing the item identity code, the items can be listed in plain language and the salesman does not have to look up item codes. The order can, therefore, be entered rapidly and transmitted back to base without danger of incorrect codes being used.
