Abstract
A reading head pauses at a predetermined position on a selected one of a plurality of series information recorded, for example, on a CD (compact disc). Either a preceding distance between a current position of the reading head on the series of information and a starting position on the series of information, at which starting position the series of information starts, or a remaining distance between the current position on the series of information and an ending position on the series of information, at which ending position the series of information ends, is indicated. The above indication is switched automatically in response to the pausing of the reading head so that the indication of a first one of the preceding distance and the remaining distance is changed to the indication of a second one thereof. Then after elapsing of a predetermined time period, the indication is automatically switched from the indication of the second one of the predetermined distance and the remaining distance to the indication of the first one thereof.
