Abstract: PURPOSE:To avoid the waste of the tape as well as to ensure an observation in detail when some change occurs by detecting the difference in the vertical correlation of the video signals and then controlling the transfer speed of the recording medium based on the difference of the vertical correlation. CONSTITUTION:The video signals are supplied through input terminal 11 to be processed, and for example the video signals equivalent to one frame are drawn out with every 1000 frames to be supplied to recording head Hr. At the same time, reproduction head Hp is provided at the position distant by 180 away from head Hr to reproduce the recorded video signals. The reproduced signals are supplied to subtractor circuit 30 to obtain the difference to the input video signals. When detector circuit 31 detects that the difference is under the fixed level, the video signals are drawn out every 1000 frames; while if the difference signal is over the fixed level, switches 16 and 26 are changed over to draw out all frames. Thus the tape speed is increased.

Abstract: PURPOSE:To improve the characteristic of the entire part by organically coupling a frequency generator to a preamplifier which draws out the output signal thereof. CONSTITUTION:Primary, secondary coils 31, 32 of a winding ratio of 1:n (n>1) secured to a magnetic core 22 encircling a yoke 14 secured to the revolving shaft 11 of a frequency generator 10 are connected to transistors 42, 43 by way of the transistor 41, capacitors 61, 62 of a differential amplifier 45. Then, when DC current is flowed to the primary coil 31, a DC magnetic flux is generated, causing the revolving shaft 11 to revolve. Then, the magnetic resistance of the magnetic path changes and alternating voltages of the frequencies determined by the teeth of gears 13, 23 and the number of revolutions of the revolving shaft 11 are generated in the secondary coil 32. The voltages are then supplied to the transistors 42, 43 and the specified output signals are drawn at terminal 71. Since the current to the coil 31 may be adjusted by a variable resistor 51, the magnetic flux of a required magnitude may be readily obtained and therefore cocking may be prevented by reducing the magnetic flux and the output signals of sufficient levels may be obtained by specifying the winding ratio of the coils 31, 32.

CONSTITUTION: After tape guide 23, 24 delivered from the different two-way system cassette supply reel 3 or 5 travels the common routes of guides 144, 145, a tape 23 is taken up by a drum 70 at an incident angle of 5° and a tape 24 is taken up at an incident angle of 5.94° by the drum 70 through gradient guides 148, 149 and a vertical guide 150 route. For the tape 24, the height of taking in the drum, i.e. the incident angle is controlled by the gradient guides 148, 149. In addition, at use of the tape 23, guides 148W150 are fallen at their sides and made out of use, and at use of the tape 24, the guides 148W150 stand upright and are on use to make possible the common use of the tape travelling system against the different two-way system tape cassette.
