PURPOSE:To make a recording device easy to use by calculating magnification which is high in frequency of use and setting the magnification high in frequency of use as memory magnification automatically a specific time later. CONSTITUTION:A control means (e) totalize the frequency of use of each magnification and stores the result in a magnification storage means (d), and magnification read out of the magnification storage means (d) is displayed on a display means (c) in the order of the frequency of use. Further, the control means (e) can sets the magnification high in frequency of use as the memory magnification automatically and control power variation. When a timer means which is not shown in a figure detects the specific time being elapsed, the obtained magnification high in frequency of use is set in a memory power varying means (b). |
