Abstract

PURPOSE:To facilitate the revision control processing and to easily read out even the information before updating by storing additionally the information on the date and time of updating into a memory medium together with the updated information when the updated information is recorded. CONSTITUTION:The updated information is recorded additionally to an unrewritable memory medium 3 for execution of the updating processing of information. In such a case, the information on the date and time of updating are additionally recorded to the medium 3 from a timepiece mechanism 4. Then the update control is carried out by means of the updated information and said additional date/time information. As a result, the update control is facilitated and both the updated information and the latest updated information can be easily processed with no complicated processing.
