Abstract

PURPOSE:To make alarm that all the cells are already in use, surely, by giving an alarm when the number of memory cells in use coincides with the total number of built-in memory cells. CONSTITUTION:When a switch 15a is turned on through the depression of a release button 15, a signal pulse phis is produced and a signal starting the pickup sequence is applied to a circuit 101 via an input terminal 101p. A symbol phibusy which indicates whether or not the pickup sequence is in progress is outputted at an output terminal 101s. The signal phibusy produces an alarm sound to a sound producing body 119 via a drive circuit 118. If all the memory cells of a storage section 2 is used out and there is no vacancy, an intermittent signal is outputted, a display device 18 is flickered, the body 119 is intermittently sounded out, allowing to display there is no memory cell not in use in the storage section 2.
