Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cassette loading device for a magnetic recording/reproducing device such as a video tape recorder.

BACKGROUND OF THE INVENTION FIG. 3 shows a conventional cassette loading device for a magnetic recording/reproducing apparatus. In FIG. 3, a cassette 1 has a pair of reels 2 on which magnetic tape is wound.

Reference numeral 3 denotes a cassette holder, and cut-and-raised portions 3a and 3b for positioning the cassette are provided at the inner bottom of the holder. Then, the cassette 1 is inserted in the direction of arrow A, and the cassette 1 is cut and raised 3a.
, 3b, and the cassette holder 3 holds the cassette 1 near the tip. A pair of semicircular holes are provided on the front side of the bottom of the cassette holder 3 to avoid the reel stand. Reference numeral 4 denotes side plates, which are located on both sides of the cassette holder 3 and are fixed to a base (not shown).

Seven long holes 4a, 4b are provided in the side plates 4 on both sides, and bosses 6a, 6b are fixed to the cassette holder 3 by passing through the long holes 4a, 4b. 5 is a wiper arm, which is provided on both side plates 4, and both wiper arms 5 are fixed together with a shaft 7. The shaft 7 is rotatably locked to the side plate 4. A long hole is provided at the tip of the wiper arm 5, and a boss 6a is engaged with the long hole. 8 is a cassette guide;
It is fixed to the side plates 4 on both sides and guides the back surface 1a of the cassette when the cassette 1 moves.

When the wiper arm 5 is rotated by a motor (not shown) in this state, the boss 6a receives force as the wiper arm 5 rotates, and moves along the shape of the long hole 4a provided in the side plate 4. . As a result, the cassette 1 held by the cassette holder 3 also moves along the elongated hole 4a. That is, in FIG. 3, it initially moves horizontally and then vertically. It can also be moved in the opposite direction by changing the rotation direction of the motor. This operation moves the cassette between the insertion position (first position) when the cassette 1 is inserted and the playing position (second position) where the reel 2 in the cassette is engaged with the reel stand and the magnetic tape can be driven. 1 can be moved.

FIG. 4 is a side view when the cassette 1 is inserted. FIG. 5 is a side view of the cassette 1 when it is moved from the horizontal direction to the vertical direction. In FIGS. 4 and 5, 9 is a reel stand, which is connected to a motor (not shown).
It engages with a pair of reels 2 in the cassette, rotates the reels 2, and as a result drives the magnetic tape. A tape post 10 pulls out the magnetic tape from the cassette and forms a predetermined tape running path. 1b is a lid of the cassette, and the lid is opened by a mechanism (not shown) when the cassette 1 moves in the horizontal direction.

Normally, a gap is provided between the back surface 1a of the cassette 1 and the slope 8a of the cassette guide 8, but when the cassette 1 is moved backwards during insertion, the cassette 1 moves on the slope 8a of the cassette guide. As the back surface 1a slides and the cassette 1 descends, it is corrected to the normal position.

Problems to be Solved by the Invention In such a conventional cassette loading device, even when the cassette 1 is inserted randomly and collides with the positioning cut-outs 3a and 3b of the cassette holder 3, it bounces and moves in a lowered state. When the amount of return is small, the back surface 1a of the cassette 1 is guided by the slope 8a of the cassette guide, but when the amount of return is large, the back surface 1a of the cassette 1 does not slide on the slope 8a of the cassette guide and is guided halfway. It gets stuck and stops. Therefore, when inserting the cassette 1, the cassette 1 must be inserted slowly and accurately, otherwise the cassette 1 will not be placed in the playing position within the deck.

Users who use video tape recorders to create soft tapes and the like tend to insert cassettes roughly and in an untidy manner, and are particularly susceptible to cassette installation failures.

The present invention is intended to solve this problem, and aims to provide a cassette mounting device that can mount the cassette without getting caught on the way even if the cassette is roughly inserted and the amount of rebound of the cassette is large.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has provided a method for inserting a cassette containing a pair of reels wound with magnetic tape into a cassette insertion slot of a magnetic recording and reproducing device from its tip, and then inserting the cassette into the insertion position. A cassette loading device that transports the cassette from the cassette to the cassette playing position includes a cassette holder that holds the cassette at the tip of the cassette, and a cassette holder that holds the cassette from the cassette insertion position horizontally to the vertical top of the cassette playing position, and then vertically to the cassette playing position. A cassette moving means for moving the holder is provided, and while the cassette holder is moving from the insertion position to the performance position, a roller that guides the back surface of the cassette protruding from the rear end of the cassette holder on its outer periphery is installed horizontally near the cassette insertion opening. It is characterized by being placed in

Effect With the above configuration, even if the cassette holder begins to move from the insertion position with a large amount of rebound of the cassette when the cassette is inserted, the back surface of the cassette is reliably guided by the outer periphery of the roller provided on the cassette guide as soon as it begins to descend. The movement of the cassette no longer stops midway.

Embodiment FIGS. 1 and 2 show an embodiment of a cassette loading device for a magnetic recording/reproducing apparatus according to the present invention. Since the same numbers as the conventional example have the same configuration as the conventional example, the explanation will be omitted.

In FIG. 1, a roller 11 is rotatably provided on a shaft (not shown) fixed to the cassette guide 8, and is located in a hole in the bottom of the cassette holder 3 to avoid the reel stand. It is set up as follows. FIG. 2 is a side view showing the point at which the cassette 1 changes from a horizontal to a vertical orientation. When it is finished, the tip of cassette 1 is cut and raised 3
Even if the cassette 1 does not come into contact with the rollers 1a and 3b and moves back in the direction of the arrow B in FIG. Cassette\ by guiding the back side 1a of set 1.

, work 1 is guided to the normal position.

Therefore, the cassette 1 is corrected to its normal position before the magnetic tape is placed on the tape post.

Effects of the Invention As is clear from the description of the above embodiments, the present invention provides a roller near the cassette insertion slot that guides the back of the cassette that protrudes from the rear end of the cassette holder, so that the cassette can be inserted with the cassette returned to the front side. However, since the magnetic tape can be reliably inserted into the inside of a video tape recorder etc., the usability of the video tape recorder etc. can be improved.
