本発明は、記録媒体の位置を数値で示す表示部
を備えた記録媒体再生装置の改良に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a recording medium reproducing apparatus equipped with a display section that numerically indicates the position of a recording medium.
磁気テープ等を記録媒体として用いるテープレ
コーダ等の記録媒体再生装置において、上記記録

表わすようにしたテープカウンタを備えたものが
ある。 In a recording medium playback device such as a tape recorder that uses magnetic tape or the like as a recording medium, when a plurality of signals such as music are discontinuously recorded (recorded) on the recording medium (hereinafter referred to as the medium), the above-mentioned It has a so-called inter-song search function that searches the recorded and unrecorded parts of multiple signals by playing the medium to find the starting position of the desired signal. Some devices are equipped with a tape counter as shown below.
このような再生装置において１曲目以上の曲間

と上記曲間信号とは無関係に各々独立されて別系
統に構成されているので媒体の記録内容の検索時
においては、記録位置つまり曲間毎のカウンタ表
示の目視による確認が不可能になる欠点があつ
た。 When searching for an interval between one or more songs on such a playback device, for example, when performing so-called skip selection, such as searching for an interval between the 5th song, it is necessary to search for an interval other than the desired one (in this case, up to the 4th song) during song selection. Even when the tape counter is searched for, it is difficult to read the tape counter display because the counter numbers pass quickly through these inter-track positions. In other words, since the tape counter and the above-mentioned inter-track signal are independent and configured in separate systems, it is impossible to visually confirm the recording position, that is, the counter display for each track interval, when searching for recorded contents on a medium. It had some drawbacks.
本発明は以上の欠点を除去するためなされたも
ので、目的以外の曲間が探された場合でも次の曲

生装置を提供することを目的とするものである。 The present invention has been made to eliminate the above-mentioned drawbacks, and even if an undesired track interval is found, the position of that track interval is displayed numerically on the tape counter until the next track interval is found. The object of the present invention is to provide a recording medium playback device configured as described above.

The figure is a schematic diagram showing a recording medium reproducing apparatus according to an embodiment of the present invention, in which 1 is a tape drive section that includes a tape 2, a supply reel 3, and a take-up reel 4;
is a tape position detection section, which counts the signal generated by the slit plate 8 (provided on the stand of the take-up reel 4) that blocks the optical path between the lamp 6 and the photoelectric element 7; It includes a counter circuit 9 for. The signals counted by the counter circuit 9 are continuously detected so as to indicate a numerical value corresponding to the position of the tape 2. 10
is the tape boundary detection unit that moves from tape 2 to magnetic head 1.
1 includes a determination circuit 12 for determining whether or not it is an inter-track portion (boundary portion) based on the magnitude of the reproduced signal detected by No. 1. Reference numeral 13 denotes a signal holding section which includes a latch circuit 14 and which is connected to the tape position detecting section 5.
and a signal from the tape boundary detection section 10 are added, and the holding state of the former signal is controlled by the latter signal. Reference numeral 15 denotes a display section, which includes a display circuit 16 and functions as a tape counter that numerically indicates the position of the tape in accordance with the signal from the tape position detection section 5.

される。 In the above configuration, when the tape 2 is played back by the tape drive section 1, the tape position detection section 5
A signal indicating a numerical value corresponding to a position on the tape 2 is continuously detected and added to the signal holding section 13. Whether or not this signal is immediately output from the signal holding section 13 to the display section 15 is determined by the signal from the tape boundary determining section 10. When the tape boundary determining section 10 determines that there is an inter-track portion of the tape 2, the tape boundary determining section 10 sends an inter-track signal [L level] to the signal holding section 13 to release the latch circuit 14 from the latched state. signal or H-level signal] is applied, the signal from the tape position detection unit 5 that was previously held in the signal holding unit 13 is released from the holding state at this moment, and the signal at this moment is output to the display unit 15. be done.
Therefore, the display section 15 (tape counter) displays a numerical value corresponding to the position of the tape at this moment.
上記曲間信号がなくなると次にテープ境界判定
部１０において曲間信号が判定されるまでの間、
テープ位置検出部５からの信号は再び信号保持部
１３に保持される。 After the inter-song signal disappears, until the next inter-song signal is determined in the tape boundary determination section 10,
The signal from the tape position detection section 5 is held in the signal holding section 13 again.
よつて表示部１５には上記曲間信号が加えられ

ので、その数値によつて現在テープ２がどの辺を
走行しているかの判断を行うことができる。 Therefore, the numerical value indicating the position of the tape when the inter-song signal is applied is displayed as is on the display section 15. In other words, the numerical value indicating the position of the previous inter-song signal (inter-song part) is fixed and displayed on the display unit 15 until the next inter-song signal is determined. It is possible to determine which side the tape 2 is running on.

板８の回転数に比例させることができる。 The tape position detection section 5 may be replaced by a linear counter proportional to the running distance of the tape 2. For example, by rotating the slit plate 8 with a roller rotated by the running tape, the running amount of the tape can be made proportional to the number of rotations of the slit plate 8.

容易に探すことができる。 As is clear from the above description, according to the present invention, even if a song gap other than the desired song gap is found, the song gap position is displayed as a numerical value on the tape counter until the next song gap is found. Since it is possible to visually check the recording position of a medium such as a tape, it is possible to easily find the starting position of a desired recording signal.
