摘要： PURPOSE:To improve operability by collecting the index information on recording information, detecting a tape winding position, writing both them to a memory and retrieving automatically the head of a program by the information acquired by reading out them and a recorded and reproduced program searching signal. CONSTITUTION:The index information on the recording year, month, and date, the recording sart and end times, the channel number and the title, etc., of the recording information are collected, and remaining amt. information of a tape is detected to calculate by S, T reel rotating speed detectors 6, 7, etc. These information are stored in an SRAM 11, when retrieval is designated by a key input device 16, a tape driving circuit 12 is driven by the information stored in the SRAM 11 and the recorded and reproduced program searching signal. The head of a selected program is retrieved automatically by this drive and reproducing is implemented. Thus, the retrieval is performed accurately without needing complicated operation and the operability is improved.

摘要： PURPOSE:To automatically equalize a counter scale, by recording a tape position information on a magnetic tape when a cassete is taken off from a device, and by presetting the tape position information to the tape position detecting device when the cassete is again loaded to the device. CONSTITUTION:The value of the counter obtained by a tape position detecting circuit 1 when the cassete is unloaded is converted into a signal by a record signal processing circuit 9 through a system control circuit 7. The counter value is recorded on the magnetic tape. Now, after the cassete is taken off from the device and other cassete is played, the aforementioned cassete is again loaded ot the device. Then, the counter value signal recorded on the magnetic tape 12 travels through closed switch contact 10c of a mode switch 10 and permanent open contact 10a to reproduction signal processing circuit 13 and converted into the counter value and taken in to the system control circuit 7, and the counter value is preset at the tape position detection circuit 1, and the value preset is outputted on a displaying device 6.

摘要： PURPOSE:To obtain an inexpensive control circuit for a power source by dividing a switching type voltage converter into a controller and a drive unit, and interrupting the supply of power only to the controller at power source interrupting time, thereby enhancing the power efficiency. CONSTITUTION:A control circuit for a power source has a DC power source 1, a switching type voltage converter drive unit 51 and its controller 50. In this case, the transistor 13 of the unit 51 is directly supplied from the power source 1, the controller 50 is supplied through a transistor 53, and the transistor 53 is controlled by the controller 52. Thus, even when the power surce is OFF, power is supplied from the power source 1 to the unit 51. At this time, since the transistor 53 is turned OFF, power is not supplied to the controller 50, and the transistor 53 does not become ON, and a current is not flowed from the power source 1.

摘要： PURPOSE:To make it easy to retrieve a program at the time of recording the program and to improve the utilization efficiency of a magnetic tape by adding a previously set keyword as program information at the time of recording the program. CONSTITUTION:When a cassette 1 is attached, a barcode 9 is decoded by a cassette identifying means 10. When it is on a recording mode, a keyword is selected from its group displayed by an OSD circuit 16 by a user and it is inputted to an input device 14. The information of a tape remaining quantity gained based on index information and a calculation is recorded together with this keyword on a SRAM 15 by a microprocessor. When a keyword retrieval is instructed by a user at the time of a reproduction, the OSD circuit 16 is controlled by a computer 11 and the keyword group is displayed on a display device. Then, given program information from the SRAM 15 is read and displayed by selecting a specified keyword. When the cassette is inserted by a user, based on the tape remaining quality, a driving circuit 13 is controlled, the first part of the program is retrieved and the reproduction is started.

摘要： PURPOSE:To automatically search a program desired to be retrieved by searching a tape cassette for a cassette number in performing a retrieval operation with a clue to a category classified in accordance with recorded contents. CONSTITUTION:Storage contents are read out of an S-RAM 8 by a microcomputer 7, and a kind of a program, for example, a program of a drama is selected, and its ontents to be displayed are displayed on a monitor 10. Then, a reference is made to the displayed contents, and a program is selected by pressing a selection completing switch, and then a tape cassette 17 stuck with a label of a bar code 16 is inserted from a cassette inserting hole 21. A tape residual time T3 is calculated by the microcomputer 7, and a difference T4 between T3 and a tape residual time T2 at the time of commencing the program is obtained, and when T4 becomes smaller than a prescribed time Tf, a detection of a program searching signal is commenced. When this program searching signal is detected, a reproducing operation is started up by the microcomputer 7, and a switch 12 is brought under the opening state to display a reproducing picture on the monitor. By this method, the retrieval operation for a desired program to be watched is feasible.
