Abstract

PURPOSE:To stop a tape correctly at a desired place even during a high speed raveling of the tape, by inputting a prescribed signal to a microcomputer and executing the traveling control of the tape. CONSTITUTION:By a tape counter, pulse signals alpha derived through an amplifier 11 are counted. The counter executes the counting-up in the quick-feeding direction and executes the counting-down in the rewinding direction. At present, when the music to be heard is jumped and the next music is to be heard, the attached switch of a recorder is pushed and a tape is traveled at a high speed; then, a quick-feeding signal alpha is outputted from a microcomputer, and by the counting-up, a motor is rotated at a high speed. Next, at the end of the music, a stopping signal beta is detected by a recording reproducing head 7. In such a case, a counting value at the occurring time of the signal beta is stored, a low speed reverse rotating signal is outputted by the microcomputer concerning the excessive part, the motor is reversely rotated and fed back by a rewinding means and at the stopping signal, the tape is correctly stopped.

However, with these tape recorders, the tape is run at high speed to find the beginning of the song, and between songs (between songs)
The recording/playback head detects this moment, generates a signal, and uses this inter-track signal to automatically stop or play. If the inter-track interval is too short, the inertia of the tape drive reel or flywheel causes the tape to will overrun and get into the beginning of the next song, making it impossible to find the beginning of the song accurately.

For this reason, a certain length is required between songs, which limits the number of songs that can be recorded on a tape cassette.
There is a very inconvenient point in the specification that when the tape is started at the beginning of the playback speed, the song begins to play after a waiting time of a little over nine seconds. It is also possible to locate the beginning of the next song accurately enough, and it is an image in the above-mentioned field of tape recorders that increases the number of songs that can be recorded on a tape cassette and eliminates the need to worry too much about the length between songs. Provide innovative inventions.

The α signal and the α signal are shown in FIG. 2. During fast forwarding, the frequency of the α signal is naturally high, and during low speed and playback, the frequency is low. First, the tape counter counts the signal α, which is a pulse derived through the amplifier 0]. This counter counts up in the fast forward direction and counts down in the rewind direction, and this is expressed as TC=O in Figure 3.

When the operator wants to skip the song he is currently listening to and listen to the next song, he presses the switch attached to the tape recorder.
The tape begins to be fed at high speed (between ■ and ■ in Figure 3), and this switch causes the microcomputer to output a fast forward signal as a control signal (Figure 3 (C)), and at the same time, the tape counter starts counting. The motor rotates at high speed (Figure 3 (a), (d))

This stop signal is the β signal described above, and is detected by the recording/reproducing head 7. However, even when this stop signal is issued, the tape does not stop immediately due to inertial force, and ends up reaching the point (2). This distance takes only a short time if the speed is high, but when it comes to playback, it cannot be ignored.
