Abstract

PURPOSE:To immediately reproduce recorded contents by a relatively simple operation by setting two series of recording/reproducing parts to one tape path. CONSTITUTION:The apparatus consists of a cassette housing part A, a first, recording/reproducing part B, a second recording/reproducing part C, a third loading mechanism D, and a tape stock part E. A magnetic tape M is taken out from a cassette V loaded in the housing part A by a guide pole 49 at the front ends of loading arms 47 and 48, and loaded to the first, recording/ reproducing part B by loading arms 8 and 9. Then, the magnetic tape M is loaded to the second recording part C by loading arms 25 and 27 to reproduce images recorded at the second recording part C by the first, recording/ reproducing part B. The magnetic tape M is temporarily stocked at the tape stock part E to bring about a time difference in reproducing the images. Accordingly, the images can be promptly reproduced without rewinding the tape after recording, or different images can be displayed at two display devices, etc., with a constant time difference.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette type magnetic recording / reproducing apparatus for immediately reproducing recorded contents, and more particularly, a time-difference magnetic recording / reproducing apparatus for immediately reproducing a swing or motion of golf, baseball or the like. Regarding

[0002]

2. Description of the Related Art Conventionally, in order to immediately reproduce the recorded contents (recording or recording), the magnetic tape is rewound for a desired time immediately after recording and the reproduction is started from that position. Also, for example, if the tape counter is set to "0000" before starting recording, a device that automatically stops at the counter "0000" when the tape is rewound after the end of recording and starts reproduction from that position, or There is known a magnetic recording / reproducing apparatus in which an electric marker signal is recorded on a magnetic tape at a desired timing, the marker signal is detected at the time of rewinding, and reproduction is automatically started from this position.

[0003]

In the conventional magnetic recording / reproducing apparatus, it is necessary to rewind to a portion to be reproduced each time, which makes the operation complicated and rewinds to a portion to be reproduced immediately. Skills are required.
For example, when a golf swing is recorded and it is desired to immediately reproduce and check the form of this swing, there is a problem that it takes a considerable amount of time to reproduce. An object of the present invention is to provide a time difference magnetic recording / reproducing apparatus capable of immediately reproducing recorded contents by a relatively simple operation.

In FIG. 3, when the video cassette V is inserted through a cassette insertion opening (not shown), the video cassette V
Is mounted in the cassette housing portion A, and the cassette housing portion A guides the video cassette V to a position where recording and reproduction can be performed by the first recording and reproducing portion B. In this state, the magnetic tape M is not pulled out from the cassette (this is called the initial state).

The video cassette V is in a state in which the magnetic tape M is wound around the supply reel S, and inside the pull-out portion M3 of the magnetic tape M, the guide roller 3 and the cap from the take-up reel T side. The stun 15, the T-side loading arm 9, the S-side loading arm 8 and the guide roller 2 are in contact with each other. The guide pole 49 attached to the tip of the loading arm 48 is arranged in the vicinity of the inside of the drawing surface M3.

Thus, in the initial state, the T-side and S-side loading arms 9 and 8 are moved to the right ends of the shaft holder guide grooves 12 and 11, and the loading arm 47 swings counterclockwise. When the edge of the loading arm 48 comes into contact with the cam guide pole 7, the swinging of the loading arms 47 and 48 is stopped. The pinch roller 14 is separated from the capstan 15.

Next, the second recording / reproducing section C is lowered by the lifting mechanism F described above, and then the loading motor 41 is rotated in FIG. 4, and the rotational power is the pulley 42, the belt 44, the pulley 43, and the rack gear. 45, Pinion Ga 4

Is a second recording / reproducing section C on the side of the cassette (downward in FIG. 4).
Is pulled out to the position where it traverses vertically. The loading arm 48 is restricted from swinging counterclockwise by a protrusion (stopper) 47b formed on the side surface of the loading arm 47.

Subsequently, the T-side loading arm 9 and the S-side loading arm 8 move leftward along the shaft holder guide grooves 12 and 11, respectively, and the magnetic tape M is loaded onto the first recording / reproducing drum 10. It
At the same time, the A / C head 13 comes into contact with the magnetic tape M from the outside, and the pinch roller 14 and the capstan 15 press the magnetic tape M.

Next, the second recording / reproducing section C is raised to the same height as the first recording / reproducing section B by the elevating mechanism F described above, and the second recording / reproducing section C is arranged in the tape path. Also, FIG.
In, the S-side loading arm 25 and the T-side loading arm 27 move to the right along the shaft holder guide grooves 31 and 32, respectively, and the magnetic tape M is loaded onto the second recording / reproducing drum 26. At the same time, the F / E head 2 via the tension arms 6 and 23
4 comes into contact with the magnetic tape M from the outside, and A / C
The head 28 contacts the magnetic tape M from the outside. Further, the magnetic tape M is pressed by a pinch roller or a capstan for back tension control (not shown) provided near the pinch roller 29, the capstan 30, and the cam guide pole 7, and the loading is completed.

After the loading is completed, a tape drive motor (not shown) drives the magnetic tape M from the supply reel S side to the take-up reel T side, and the first or second recording / reproducing drums 10, 26 record an image. Is played.

On the other hand, the unloading operation is the reverse of the loading operation. In FIG. 1, first, the magnetic tape M is removed from the second recording / reproducing drum 26, then the magnetic tape M is removed from the first recording / reproducing drum 10, and then the second recording / reproducing section C is lowered by the elevating mechanism F. Then, finally, the loading arm 47 swings counterclockwise, and the edge of the loading arm 48 comes into contact with the cam guide pole 7, whereby the movement of the loading arm 47 causes the guide pole 4 to move.
9 is arranged at the above-mentioned initial position (FIG. 3).

By the way, according to the first aspect of the invention, the magnetic tape M is pulled out by the guide pole 49 at the tip of the loading arm 48 to a position where the magnetic tape M crosses the second recording / reproducing section C vertically.
Further, the configuration until the magnetic tape M is loaded on the first recording / reproducing drum 10 and the second recording drum 26 is applicable.
