Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention relates to a sound in which a reproduction signal from a CD (compact disc) player set at N times speed is reciprocally recorded on a cassette tape at N times speed. The present invention relates to a recording / reproducing device for use.

(Prior Art) Generally, when a playback signal of a CD player is reciprocally recorded on a cassette tape, a leader portion is provided at the beginning and end of the cassette tape, and recording cannot be performed on this leader portion. When the cassette tape switches from forward to reverse at the time of reciprocal recording, the reproduction signal is lost during the traveling of the cassette tape at the start and end of the leader. Therefore, in recent reciprocating tape recorders, when the cassette tape is recorded in the reverse direction, the CD player returns to the beginning of the song being played, and waits for the leader of the cassette tape to finish running, and after a set time It is controlled to play from the beginning of the song.

Recently, a CD player and a reciprocating cassette tape recorder have been operated at high speed in order to reciprocally record a reproduction signal of a CD player on a cassette tape in a short time. FIG. 3 shows a procedure of a program for operating a conventional CD player and a reciprocating tape recorder at N times speed, and reciprocally recording the reproduction signal of the CD player in the reverse direction from the beginning of the music to the cassette tape by microcomputer control. .

Hereinafter, the conventional N-speed recording will be described with reference to FIG.

Judging whether dubbing key is operated in the S ₁ but operation is completed, a timer is set for setting the time to pause the CD player when switched by S ₂ in the reverse direction. Determine normal dubbing at S _3, if normal dubbing, set the tape recorder to dub state S _4, the CD player in S ₅ constant speed reproduction, starts dubbing of the reproduced signal of the CD player. If the normal dubbing at S _3, and sets the CD player and the tape recorder in S ₆ the N-times speed, dubbing set at S _7.
The CD player to start playback of N times faster S _8, to start the N-speed recording. Constant speed or N-times speed dubbing a cassette tape S _9, it is determined whether the reverse direction, if the reverse direction, to pause the CD player in S _10, starts the counting of the timer which is set at S ₂ in S ₁₁ .
S ₁₂ determines whether the time that timer setting is over, if I was over, to release the pause of the CD player, to start the dubbing again. At this time, the CD player may perform control such that when the music is in the middle of the music before the reverse, the music is reproduced from the beginning of the music.

(Problems to be Solved by the Invention) In the above-described conventional device, the time from when the cassette tape enters the reverse recording state to when the paused CD player is reproduced again is determined by the head of the cassette tape. The time until the end of the run is slightly longer to allow for room. In a short time period to wait for a CD player when the CD player and the tape recorder is operated in the normal N times speed in order to reciprocatingly record reproduction signal of a CD player to a cassette tape as a T _1, passing through the reader unit When the time is for T _2, since the reader unit passes at T ₂ / N,
During the time of (NT ₁ −T ₂ ) / N, a non-recordable portion occurs in a recordable portion of the cassette tape. When this is reproduced at a constant speed, N × T ₁ when inverted from forward to reverse.
Time of no signal of + T ₂ has occurred.

The present invention eliminates the above-mentioned problems, and even when recording back and forth from a CD player to a cassette tape in a short time,
It is an object of the present invention to set the waiting time of the CD player in accordance with the traveling speed, and to set the same non-signal time at the time of reversal as when recording and reproducing at a constant speed during reproduction.

[Structure of the Invention] (Means for Solving the Problems) An audio recording / reproducing apparatus according to the present invention comprises: a compact disc reproducing unit capable of reproducing a compact disc at 1x speed or Nx speed according to a command; The cassette tape recording unit that can record the playback signal of the unit on the cassette tape at a speed corresponding to the playback speed of the compact disk playback unit, and the cassette tape when the cassette tape reaches the end during dubbing from the compact disk to the cassette tape Means for inverting the running direction of the cassette tape and suspending the playback operation of the compact disc playback unit for a set time, and the no-signal time at 1x speed playback at 1x speed after the running direction of the cassette tape is inverted. 1x speed so that the case of dubbing at N times and the case of dubbing at N times speed are almost the same Each of the time set in operation and in N-times speed dubbing dubbing, the first a first predetermined time 1
And a stop time variable setting means for variably setting the time to a second predetermined time that is 1 / N times the predetermined time.

(Operation) In the present invention, the first time is set during 1 × speed dubbing as a set time for temporarily stopping the reproduction operation of the compact disk reproducing unit when the cassette tape reaches the end during the dubbing from the compact disk to the cassette tape. The predetermined time, at the time of dubbing at N times speed, the second predetermined time of 1 / N times the first predetermined time is variably set, so that dubbing at 1 times speed and dubbing at N times speed are performed. Thus, the non-signal time at the time of 1 × speed reproduction after the running direction of the cassette tape is reversed can be substantially matched.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
