Abstract

PURPOSE: To make it possible to know the accurate quantity of a tape run and that of its remainder immediately by simultaneously carrying out digital display of the rotation detection signal of a reel converted into the quantity of a tape run and analog display by level indication.
CONSTITUTION: With switch S1 connected to contact (a), digital display unit DID is driven to display digital time on display unit DID in parallel to the display of a reproduction output level, obtained by compressive amplifier CPA1 and A/D converter A/D1, on analog display unit AID. With this switch S1 connected to contact (b), selector SEL1 selects the digitally-converted quantity of a tape run according to the rotational frequency of a reel detected through rotation signal generator RTP and run-quantity converter circuit RCV and performs digital display by display unit DID. Simultaneously, the analog run quantity obtained by decoder DEC2 through SEL2 is displayed by display unit AID for level display, so that the accurate digital tape run quantity and analog tape run quantity for an immediate decision on the quantity of the remainder will be displayed in parallel.
