Abstract

A signal reproduction apparatus is disclosed, which simply permits control operations in operation control modes absorutely corresponding to detection regions of the touch panel and also various controls, e.g., speed control and feed control or the like corresponding to changes of the touch operation state of the touch panel with the lapse of time. The apparatus thus improves the operation control property of a multi-function VTR including JOG mode functions or the like.

Claims

1. Signal reproduction apparatus for reproducing one of a video signal and an audio signal from a recording medium, comprising:

panel means having a plurality of detection regions;

touch detection means for detecting a touched state of each of said detection regions and producing detectio output data in response thereto;

first memory means for temporarily storing said detection output data from said touch detection means;

recognition means for recognizing composite touched states of said panel means as respective patterns in response to detection output data read out from said first memory means and producing pattern data corresponding to the recognized patterns;

second memory means for temporarily storing said pattern data obtained from said recognition means;

data comparison means for comparing first pattern data corresponding to the pattern recognized from a prevailing composite touched state and obtained from said recognition means with second pattern data corresponding to the pattern recognized from a preceding composite touched state and obtained from said second memory means and detecting a change between said first and second pattern data, said data comparison means producing comparison output data corresponding to the detected change in response thereto;

control data generating means for providing control data according to said comparison output data obtained from said data comparison means;

data reading means for reading the one signal from said recording medium;

drive means for producing relative movement between said data reading means and said recording medium at respective relative speeds; and

drive control means for controlling the relative speeds of said data reading means and said recording medium in response to said control data so as to reproduce the one signal from said recording medium at a corresponding speed.

2. The signal reproduction apparatus according to claim 1, wherein said touch detection means includes scanning means for detecting the touched state of each of said detection regions through scanning thereof, thereby detecting the composite touched state of said panel means at predetermined intervals.

3. The signal reproduction apparatus according to claim 2, wherein said panel means includes pulse generating means generating pulses at said predetermined intervals, a plurality of detection electrodes arranged in a row and spaced apart by a predetermined distance and connected to said pulse generating means, a plurality of grounding electrodes arranged alternately with said detection electrodes, and an insulating layer provided on said detection electrodes and said grounding electrodes so that when a portion of said insulating layer overlying a detection electrode and an adjacent grounding electrode is touched by a person, a capacitance between the detection electrode and the grounding electrode under the touched portion is changed, the change in the capacitance being detected by said touch detection means in response to said pulses.

4. The signal reproduction apparatus according to claim 2, wherein said tape drive control means causes said selected signal to be reproduced at a speed corresponding to a distance between a first position at which said touch detection means detects that said panel means is touched at one time and a second position at which said touch detection means detects that said panel means is touched a predetermined period of time afterwards, said signal being reproduced in a forward or reverse direction corresponding to a direction of movement from said first position to said second position.

5. The signal reproduction apparatus according to claim 2, wherein when the prevailing composite touched state includes a prevailing touched position at which said touch detection means detects that said panel means is touched which is increased in a direction with respect to a previous touched position a predetermined period of time before, the selected signal is reproduced at a speed corresponding to the interval of increase between the prevailing and previous touched positions and in a forward or reverse direction corresponding to the direction of increase to said prevailing touched position.

6. The signal reproduction apparatus according to claim 1, wherein said panel means has an annular shape to provide for touch operation in a sense similar to that of a dial.

7. A video signal reproduction apparatus for reproducing a video signal from a magnetic tape, comprising:

panel means having a plurality of detection regions;

scanning means for detecting a touched state of each of said detection regions through scanning thereof at predetermined times and providing detection output data indicative of a composite touched state of said panel means;

first memory means for storing said detection output data obtained from said scanning means for each predetermined time;

recognition means for recognizing composite touched states of said panel means as respective patterns in response to detection output data read out from said first memory means and producing pattern data corresponding to the recognized patterns;

second memory means for temporarily storing said pattern data obtained from said recognition means;

data comparison means for comparing first pattern data obtained from said recognition means at one time with second pattern data obtained at an instant a predetermined period of time before and read out from said second memory means to produce comparison output data corresponding to a detected change between said first and second pattern data;

control data generating means for providing preset control data according to said comparison output data obtained from said data comparison means;

signal reproducing means; and

drive means for obtaining a reproduced image signal at a selected speed by driving said magnetic tape at a speed corresponding to said control data relative to said signal reproducing means.
