KR950025691A - Automatic music playback device of cassette tape recorder - Google Patents

Abstract

When the user operates the up / down auto selection key to listen to a desired song, the present invention displays the number of times the up / down auto selection key operation is performed and the sound existing between continuous audio information recording sections on the magnetic tape. It relates to an automatic selection playback apparatus of a cassette tape recorder for performing automatic selection playback of a desired song when the number of detections of the interval is equal to the up / down automatic selection key manipulation times. A mode memory in which an automatic selection button unit 10 capable of designating a song and an automatic selection up regeneration mode or an automatic selection down regeneration mode according to operation of up / down automatic selection keys on the automatic selection button unit 10 are temporarily stored. The unit 20, a deck mechanism 30 for driving the audio tape to a desired operating state, and the number of times the up / down automatic bending machine operation is displayed. Display means 40, audible signal detecting means 50 for detecting an audible signal sound between the audio information recording section and the silent section existing on the audio tape, and the up / down automatic selection according to the automatic selection up / down reproduction mode. The number of key manipulations is displayed on the display means 40, and the audible signal sound level detected by the signal sound detection means 50 is compared with reference data to detect a silent section and at the same time the numerical value of the detected silent section is detected. The control means 60 is configured to control the driving of the deck mechanism 30 while counting correspondingly to the up / down automatic selection key operation times.

Claims (3)

Auto selection button unit 10 that can designate a desired song to be repeatedly played by the user, and auto selection selection playback mode or auto selection down according to the operation of the up / down auto selection key on the auto selection button unit 10. A mode memory 20 for temporarily reproducing the mode, a deck mechanism 30 for driving the audio tape to a desired operating state, display means 40 for displaying the number of times the up / down automatic selection key operation is performed, and an audio tape image. An audible signal detecting means 50 for detecting an audible signal sound between the audio information recording section and the silent section existing in the audio information recording section; The audible signal sound level detected by the signal detecting means 50 is compared with reference data to detect a silent section, and the numerical value of the detected silent section is displayed. / Down automatic selection of music and count correspondingly to the key-operated automatic selection of music number reproduction device of the cassette tape recorder according to claim consisting of a control means 60 for controlling the driving of the mechanism deck 30. The An apparatus for automatically selecting and playing cassettes according to claim 1, characterized in that the display means (40) is composed of two sets of seven segment LEDs. 2. The control means (60) according to claim 1, wherein the control means (60) stores an A / D converter (61) for digitally converting the detection signal from the tone detection means (50), and reference data for comparison with the digitally converted data. A comparison data storage section 62, a comparison section 63 for comparing the digitally converted data with the reference data, and an up / down automatic selection key manipulation count on the automatic selection button section 10; If the two comparison data to be compared in the comparison unit 63 is the same, counting means 64 for counting up, and outputting the display control signal so that the up / down automatic selection key operation frequency is displayed on the display means 40 On the contrary, if the two comparison data are not the same as the result of the comparison in the comparison unit 63, it is determined that the audio information recording section is being read out. If it is determined that the section is being read and the number of detected silent sections is equal to the number of times of up / down automatic selection key operation stored in the counting means 64, the tape reel driving control is performed so that the playback operation is performed at the position. A controller 65 for outputting a signal, a tape reel driver 66 for driving a tape reel in accordance with a tape reel drive control signal from the controller 65, and a drive according to a display control signal from the controller 65; An automatic selection playback apparatus for a cassette tape recorder, characterized by comprising a display driver (67). ※ Note: The disclosure is based on the initial application.
