CONSTITUTION:When an F-cassette mode is selected by a selecting SW 17, this is detected by a system controller 15, where control signals 1b and 1d are changed, and an output 1f to the display 16 is changed, and hence a command is outputted to the display 16 to show it as an F-cassette mode. Then, when an F-cassette is inserted, an output 1c of an F-mode SW 13 is changed, and it is detected by the system controller 15 that the F-cassette has been inserted. Then, the control signal 1d is changed in order to enable a tape to travel, and an F-cassette holder mechanism 14 is operated, so that the F-cassette is moved into a loading position. In this case, since the F-mode SW 13 is also moved interlocking with this, the output signal 1c of the F-mode SW 13 is read by the system controller 15, so that it is detected that the F-cassette is in the loading position. By this method, the user can be informed of the specification of a cassette in use.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a magnetic recording/reproducing device (hereinafter abbreviated as VTR) that can use a plurality of cassettes of different standards.

2. Description of the Related Art In recent years, camera-integrated VTRs are generally equipped with not only a recording function but also a playback function. However, there is a strong desire to play back cassettes recorded with an integrated VTR on a stationary VTR, but if the cassette standards are different between the integrated VTR and the stationary VTR, a cassette adapter must be used. However, it is very complicated. Therefore, it is desirable to commercialize a stationary VTR that can use multiple standard cassettes. Now, we will explain how to use conventional cassette adapters with the VH8 standard cassette (hereinafter abbreviated as F cassette), which is one of the standards for home VTRs, and the compact cassette (hereinafter abbreviated as C cassette). will be explained using drawings as an example.

FIG. 2 is a block diagram showing a conventional VTR cassette holder mechanism and its control device. 21 is a system control microcomputer (hereinafter referred to as a system controller) that controls the entire VTR, and 22 is the position of the cassette holder. 2& is its output signal, 23 is the cassette holder mechanism, 2b is a control signal from the system controller, 24 is a display word to indicate that a cassette has been inserted, 2C is a mode switch that is linked to the cassette holder to notify the system controller. This is a control signal from the system controller that indicates that a cassette has been inserted.

The operation when an F cassette is used in the VTR configured as above will be explained. When the F cassette is inserted, the output 2a of the mode SW 22 changes, and the system controller 21 detects that the cassette has been inserted. Then, the system controller 21 changes the control signal 2b to enable the tape to run, operates the cassette holder mechanism 23, and moves the cassette to the mounting position. At this time, mode 5W22 is also linked, so the system controller 21 is in mode 5.
By reading the output signal 2a of W22, it is possible to detect that the cassette is at the loading position. However, the system controller 22 changes the control signal 2C, and the display 24 indicates that a cassette is inserted.

Next, the operation when a C cassette attached to the cassette adapter is used will be explained.

According to the VH3 standard, the F cassette and C cassette adapters are
They have exactly the same shape. When the cassette adapter is inserted, the output 2a of the mode SW 22 changes, and the system controller 21 detects that the cassette has been inserted. and,
The system controller 21 changes the control signal 2b to enable the tape to run, operates the cassette holder mechanism 23, and moves the cassette to the mounting position. At this time, mode 5W22 is also linked, so the system controller 21 uses mode 5W.
By reading the output signal 2a of 22, it can be detected that the cassette is in the loading position. However, the system controller 22 changes the control signal 2C, and the display 24 indicates that a cassette is inserted.

As mentioned above, in current VTRs, both the F cassette and the C cassette attached to the cassette adapter operate in exactly the same way.

Problems to be Solved by the Invention However, in the above configuration, the indicator only functions to indicate that a cassette has been loaded.

There was a problem in that the user did not know which cassette was being used.

In view of the above problems, the present invention is a VTR that can operate an F cassette and a C cassette without using an adapter.The present invention provides a VTR that can operate an F cassette and a C cassette without using an adapter. The purpose of this invention is to provide a VTR that makes it possible to notify the standards of the cassettes currently available.

Means for Solving the Problems In order to solve the above problems, the magnetic recording and reproducing apparatus of the present invention has a control device that controls the operation of each A cassette holder to determine which standard cassette can be used or is in operation. This includes a circuit that outputs a signal representing the cassette, and a display circuit that displays the standard of the cassette.

Function: With the above-described configuration, the control device for controlling the operation of each cassette holder outputs a signal representing the state of the cassette holder to the display, and the display displays the standard of the cassette. You can know the specifications of the cassette you are using.
