(産業上の利用分野)
本考案は、カセツトテープレコーダのような記
録再生が可能な装置において、歌曲などを記録し
直す場合に用いられる記録情報のとり直し装置に
関する。[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to an apparatus for re-recording recorded information used when re-recording a song or the like in a device capable of recording and reproducing, such as a cassette tape recorder.
(従来の技術)
カセツトテープレコーダにおいては、録音する
歌曲間に無信号部分を持たせて録音を行なうが、
ある歌曲の録音に失敗した場合、その歌曲の頭出
しを行わせる録音一発とり直し装置を備えたもの
がある。その従来装置においては、第1図に示す
様に、録音とり直しを行なう場合、録音途中から
レビユーに入り、(1)、曲間即ち録音失敗した歌曲
の先頭部とその前の曲の終端部との間の無信号部
分を検出し(2)、曲間を検出すると録音ポーズのモ
ードに入る(3)という動作を行なつていた。(Prior art) In a cassette tape recorder, recording is performed with a no-signal portion between recorded songs.
Some devices are equipped with a one-shot re-recording device that allows you to pick up the beginning of a certain song if it fails to record it. As shown in Figure 1, when re-recording, the conventional device enters the review from the middle of the recording, and (1) starts between the beginning of the song where the recording failed and the end of the previous song. It detects a no-signal portion between songs (2), and when it detects an interval between songs, it enters recording pause mode (3).
(考案が解決しようとする課題)

部分が形成されず、最悪の場合、前の曲の終端の
信号記録部分を消してしまうことがあつた。(Problem to be solved by the invention) However, in this conventional device, when detecting a gap between songs and entering a recording pause, the tape starts rotating at high speed and then stops, so when it stops, the erase head or recording head ( (including the recording/playback head) may move to a position opposite to the end of the previous song, and the stopping position also varies. Therefore, when the next recording is made, the no-signal portion between songs is not formed, and in the worst case, the signal recorded portion at the end of the previous song may be erased.
本考案は、上記した点に鑑み、ある記録情報を

After the control means and the recorded information section detecting means restart detecting recorded information, the magnetic tape is erased when the recorded information section detecting means detects a change in state from a no-signal portion to a signal present in the recorded information section. The present invention is characterized by comprising a rewind control means for rewinding the tape by the distance between the head and the recording/reproducing head or by a length slightly larger than the distance.

制御手段である。 FIG. 3 is a functional block diagram realized by the apparatus shown in FIG. 2, in which reference numeral 12 indicates an operation command means such as a switch for commanding one-shot music selection, and reference numeral 13 indicates a device for performing a review operation when the command is given. While I was there,
A no-signal portion detection means 14 for detecting a no-signal portion (between songs) is enabled to operate when a no-signal portion is detected, and changes from the no-signal state of the no-signal portion to the state of the recorded information section with a signal. Recorded information portion detection means 15 detects a change, and reproduction control means 15 performs a reproduction operation after a no-signal portion is detected. 1
Reference numeral 7 denotes an operation control means for stopping the detection operation for a predetermined period of time (the time during which the tape can be moved by the reproducing operation until the recording/reproducing head is located in the no-signal area) after the start of reproduction. 16 is recorded information section detection means 1
4, when a change in state from the no signal state of the no signal part to the state of the recorded information part with a signal is detected,
This is a rewind control means for rewinding the tape by the distance between the erasing head and the recording/reproducing head or a length slightly larger than the distance.

ドとする。(21,3)。 FIG. 4 is a flowchart explaining the operation of this embodiment, and during the transition from the no-signal portion (between songs) detection operation (2) to the recording pause (3) in the operation of FIG. Step 21) is included. That is, when a no-signal portion (between songs) is detected by the no-signal portion detection means 13 during a review (for example, if a no-signal period continues for 0.1 seconds, it is determined that it is a song interval), the playback control means 15 detects a no-signal portion (between songs). is activated and begins playback operation (18).
Specifically, when the no-signal portion detection signal from the recording/reproducing head 4 is input to the microcomputer 7, the drive section 11, which had previously kept the high-speed plunger 9, the rewinding plunger 10, and the play plunger 8 in operation, is activated. The operating state of is switched to a state in which only the play plunger 8 is operated. At this time, if the stop position of the tape varies and the tape stops at the end of the recorded information section (the end of the previous song) before the no-signal section, the recording information section detecting means 14 immediately enters playback operation. When a signal from the head 4 is detected, a change in state from no signal to a signal is mistakenly detected as a curved head, causing the rewind control means 16 to rewind the tape. In order to prevent this, at the same time as playback starts, the recording information portion detecting means 14 performs a timing operation (specifically, an operation that generates a signal when a predetermined number of clock pulses obtained by dividing the clock pulse of the microcomputer is counted). , recording information section detection means 1 for a predetermined time
4 (19), the operation control means 17 operates. That is, the microcomputer 7 ignores the output of the clipping amplifier 6 until the end of the previous song has passed, and then detects the portion (the beginning of the song) where the no-signal portion changes to the signal-present portion (20). The positional relationship between the tape and the head when the beginning of the track is detected is as shown in FIG. In FIG. 5, 22 is a recording/reproducing head, 23 is an erasing head, A indicates the position of the tape when the beginning of a song is detected, a is an inter-track portion, and b is a song portion. When the curved head is detected, the rewinding control means 16 is activated, and the rewinding plunger 10 shown in FIG. 23 or earlier, and then the recording pause mode is set. (21,3).

部分の消し残りもなくなる。(Effect of the invention) As mentioned above, after the song interval is detected during review, playback operation begins, and during playback operation, the recording information section is detected only for the time that the tape moves beyond the end of the previous song. This operation is not performed, and when the beginning of a song is detected, it is rewound by the interval between the erase head and the recording/playback head, so it is possible to erase the area near the end of the previous song. There are no gaps between songs, and there are no unerased areas where recording failed.
