Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic recording and reproducing apparatus for recording and reproducing audio signals, video signals, etc. on a magnetic tape housed in a tape cassette.

BACKGROUND ART AND PROBLEMS Conventionally, magnetic recording and reproducing apparatuses have been proposed that have a tape loading mechanism that loads or unloads a magnetic tape stored in a tape cassette into or from a magnetic head unit. In such a magnetic recording/reproducing device, in order to mount the tape cassette at a predetermined cassette mounting position, it is necessary to move only the tape cassette into the housing of the device.
There is a cassette loading method in which the tape cassette is loaded into the cassette loading section, and a front loading method in which the entire cassette loading group is moved into the housing.

In the case of this cassette loading method, the inserted tape cassette is transported horizontally and then vertically, and the tape cassette is installed at the cassette mounting position, so there is a space for vertically moving the tape cassette, the so-called dead space. This requires a lot of space, and the total thickness of the five devices increases in the vertical direction due to this dead space.

In addition, in this cassette loading method, after the tape cassette is mounted in the cassette mounting position, the magnetic tape stored in the tape cassette must be loaded into the magnetic head mounting section, and the cassette mounting operation and tape loading operation are separated. Since these operations cannot be performed simultaneously, a relatively long time is required from the insertion of the cassette to the transition to the recording or playback state.

On the other hand, in the case of the front loading method, since the tape loading operation is performed after the movement of the cassette loading section, there is no problem with the put space as in the cassette loading method, but like the cassette loading method, the recording or playback status starts from the insertion of the cassette. It took a relatively long time to transition to .

OBJECTS OF THE INVENTION In consideration of the above points, the present invention aims to provide an apparatus which can shift from insertion of a cassette to a recording or reproducing state in a relatively short time and which can be made relatively thin.

Summary of the Invention The present invention provides a cassette mounting mechanism for mounting a tape cassette containing a magnetic tape in a predetermined position, a magnetic head unit for performing predetermined recording or reproduction on the magnetic tape,
The moving part is provided with a tape loading mechanism for loading or unloading the magnetic tape of the tape cassette onto or from the magnetic head device Qi, and the moving part is moved to a closed position within the housing and to a horizontal direction iZ with respect to the closed position. The magnetic recording and reproducing apparatus of the present invention is configured such that it can be moved between an open position outside the housing and a tape loading mechanism that performs loading when the moving part moves from the open position to the closed position. This method has the advantage of being able to transition from a cassette to a recording or reproducing state in a relatively short time, and of making the device relatively thin.

Since the loading is performed by (b), there is an advantage that the transition from cassette insertion to the recording or playback state can be made in a relatively short time. In addition, since the vertical movement of the tape cassette (5) necessary for loading the cassette is made using the upper space of the moving part (2) that is skated to the oven position, the tape cassette (5) required for loading the cassette can be moved in the vertical direction. (5) The dead space for movement in the vertical direction can be made relatively small, and there is an advantage that the width of the device can be made thinner by that amount. Furthermore, the opening and closing of the cassette holder (4) is released for skating the moving part (2) from inside the housing (1) to the oven position, so that the moving part (2) is not in the oven position. It is easy to use as there is no need for any operation to eject the tape cassette (5) in the closed state.

FIG. 11 shows another embodiment of the main part of the present invention. This first
In FIG. 1, parts corresponding to those in FIGS. 1 to 10 are designated by the same reference numerals, and detailed explanation thereof will be omitted.

In this example, one dual-purpose motor (73) is provided at a predetermined position on the lower surface side of the board (14) for driving skating and loading, and two motor pulleys are attached to the shaft of this dual-purpose motor (73). 8a) and (60a), which are constructed in the same manner as in the above embodiment, and when the close operation is selected by the open/close button (3) and the completion of cassette loading is detected by the cassette loading completion detection switch (23). By rotating this dual-purpose motor (73) in the normal direction, the moving part (2) is skated to the closed position and the tape loading mechanism (50a) is activated.
(50b) to (70a) (70b) load the magnetic tape, and detect that the open operation is selected by the open/close button (3) and the stop mode is selected by the rotary encoder (67). When this occurs, the dual-purpose motor (73) is reversely rotated to skate the moving part (2) to the open position and also to activate the tape loading mechanism (50a).
) (50b) ~ (70a) (70b)
to unload the magnetic tape.

It will be easily understood that the same effects as the embodiments shown in FIGS. 1 to 10 described above can be obtained in this embodiment as well.

In the above embodiment, when skating the moving part (2) to the closed position, the completion of cassette mounting is detected by the cassette mounting completion detection switch (23), and the close operation is selected by the open/close button (3). The following describes the case where the skating motor (8) is rotated forward when the skating motor (8) is rotated forward when the skating motor (8) is rotated in the forward direction. It is easy to understand that the same effects as in the above-mentioned embodiment can be obtained even if the moving part (2) is skated to the closed position by rotating the moving part (2) in the normal direction. In the above embodiment, the lock pin (2) is locked by the lock claws (31a) (31b) of the lock levers (30a) (30b).
7a) Remove the locking IW of (27b) with the protruding piece (1b
) and release levers (42a) (42b), etc., and a more mechanical mechanism, but a detector for detecting the position of the moving part (2) and a plunger controlled by this detector are also used. Alternatively, the process may be performed more electrically.

Furthermore, it goes without saying that the present invention is not limited to the above-described embodiments, and can take various other configurations without departing from the gist of the present invention.

Effects of the Invention According to the magnetic recording/reproducing apparatus of the present invention, a cassette mounting mechanism for mounting a tape cassette containing a magnetic tape in a predetermined position, and a magnetic head unit for performing predetermined recording or reproduction on the magnetic tape are provided. The moving part is provided with a tape loading mechanism for loading or unloading the magnetic tape of the tape cassette into or from the magnetic head unit, and the moving part is located at a closed position within the housing and in a horizontal direction with respect to the closed position. It can be moved between the open position outside the housing and the tape loading mechanism is used when the moving part moves from the open position to the closed position.
There are advantages in that the transition from cassette insertion to the recording or playback state can be made in a relatively short time and that the thickness of the device can be relatively thin.
