Abstract: PROBLEM TO BE SOLVED: To confirm whether equipment to be charged is regular, without using any communication means such as light. SOLUTION: When equipment 11 to be charged is placed in a charger 1, charging is started automatically. In the equipment 11, a charge control part 15 turns off a charge off switch 16 by a fixed period according to a signal from a timer 14. When charge is turned off in this manner, temporary increase in the voltage of a transmission coil 4 is repeated with a fixed period. In the charger 1, a confirmation detecting part 5 detects the change in the voltage of the transmission coil caused 4 by the on/off of the charge. A control part 2 determines whether the equipment 11 is regular, according to a signal that is outputted from the confirmation detecting part 5. When it is determined that equipment is not the equipment 11, a power transmission part 3 is controlled, and the charge to the equipment 11 is stopped.

Abstract: PURPOSE:To decrease the lock-in time of an AFT system servo controller as much as possible by skipping the circulating order of a reference pilot signal by the prescribed number of stages when a reproducing head is placed at the oscillating position of a tracking controller. CONSTITUTION:When a level of an oscillating error signal S24 fed to a level detecting circuit 44 is higher than an output of a threshold level voltage source 45, an oscillating point detecting circuit 31 transmits a signal S25 to a skip discrimination circuit 50 to feed a skip signal S27 to switch circuits 17, 32. A control condition signal SEL2 to switch circuit main bodies 17A, 23A is inverted for the logical level by the skip signal S27 to advance or retard the switching order of the frequency of reference pilot signals S11, S31 by 1/2 frequency-division period. The pilot signal reference signals S11, S31 are skipped at start of reproduction to apply immediate lock-in to the tracking controller.

Abstract: PURPOSE:To record different kind of programs in cassettes socked in a cassette changer individually, by performing cassette changing operation by receiving an operation end signal from a timer inter-locking with recording operation. CONSTITUTION:A VTR performs recording operation under the control of a timer 17 and at an operation end time stored in the timer, an operation end signal Ee stored in the timer is supplied to the control circuit 15 of a cassette chnager 1. As a result, the control circuit supplies an ejection signal Ej to the system control circuit 16 of the VTR, and the loading of a tape is released to replace a cassette in operation with new one. On the replacemet of the cassette, a recording command signal REC is supplied to the system control circuit of the VTR and while a recording mode is set, the power source is turned off, so that the VTR is held in readiness for recording until the timer outputs the next operation start signal.

Abstract: PURPOSE:To prevent the flicker of a picture, and in addition, to obtain a good non-interlaced picture data free from a sense of incongruity by superimposing a reproduced picture with the picture formed by a computer through a field memory or a line memory respectively according as a reproduced picture is a still picture or a moving picture. CONSTITUTION:A still picture reproduced picture through an A/D converter 2 and the picture formed by the computer through a delay circuit 6 are stored in the field memory 8 whose reading speed is twice as fast as its writing speed as the superimposed still picture through a first picture data selecting device 4. On the other hand, in the case the picture from the converter 2 is the dynamic picture, they are stored in the line memory 3 whose reading speed is twice as fast as its writing speed, and the contents of the memories 8 and 3 are selected through a second picture data selecting device 9 according to the still picture or the moving picture, and the superimposed picture is outputted. Thus, by using the optimum memories respectively to the still picture and the moving picture, the flicker of the picture can be prevented, and simultaneously, the good non-interlaced picture free from the sense of incongruity can be obtained.

Abstract: PURPOSE: To detect satisfactorily leading and trailing ends of magnetic tape even if a magnetic substance of the tape is flaked off or the travel speed of the tape fluctuates by changing the period of a sampling pulse in accordance with the travel speed of the magnetic tape.
CONSTITUTION: The device 7 detects the travel speed of the magnetic tape, and the sampling pulse of a prescribed period is outputted from a generator 8 corresponding to a travel speed pulse in accordance with this detected travel speed. Thus, the leading and trailing ends are decided irrespective of the tape travel speed, and a signal from a system control circuit 11 changes an operation mode. Only when the counting which corresponds to a prescribed set value is obtained in succession, a control signal for stopping the tape travel is supplied to the circuit 11. Although a light beam reaches a photo transistor 1 due to the flaking of the magnetic layer off the tape, the counting will not be carried out up to the prescribed set value, thus avoiding erroneous detection.

Abstract: PURPOSE:To insert a cassette into a cassette holder automatically and securely with mechanically storing force by pressing the cassette from behind mechanically for the insertion. CONSTITUTION:The cassette 7 passes over a press-in arm 30 right before being inserted into the cassette holder 3, but a microswitch is changed over by a cassette detection lever in the way of the insertion to drive a press-in arm driving shaft 6 normally, so that the press-in arm 30 is driven in a direction G to rotate normally. Consequently, the forward part of the press-in arm 30 abuts on the rear end of the cassette 7 to press the cassette into the cassette holder 3 by mechanically strong force. Then, a cassette ejection spring is charged with force by the pressing-in force of this cassette 7.
