Description

[Detailed Description of the Invention] (i) Technical Field The present invention relates to an improvement of a guide for a cassette house mirror of a video tape recorder or the like.

(ii) Background Art A video tape recorder is generally equipped with a front loading type cassette house having an up/down type cassette tape monitoring mirror. In this type of cassette house, a cassette holder is disposed within the cassette house body so as to be movable back and forth and up and down, and after inserting the cassette tape into the cassette holder, the cassette holder is moved diagonally downward to bring the cassette tape into a loading state. At this time, the monitoring mirror rotatably attached to the inner surface of the upper part of the cassette house body tilts approximately 45 degrees as the cassette holder moves.
It is configured so that the remaining amount of tape can be monitored from the outside.

As shown in FIG. 1, a conventional cassette house of this type has a mirror 2 attached to the inner surface of the upper part of the cassette house body 1 so as to be rotatable in the direction of arrow A by means such as a hinge, and a mirror 2 at the bottom thereof. A cassette holder 3 is arranged movably in the directions of arrows B and C. A cassette tape 4 is inserted into the cassette holder 3. A metal plate 5 extending in the width direction is attached to the upper part of the cassette holder 3, and a mirror guide 6 having a smooth surface is attached to the upper surface thereof with double-sided tape or the like. In use, when inserting the cassette tape 4 into the cassette house, the cassette holder 3 is located above and the sheet metal 5
is in a state where the mirror 2 is pushed up to the position shown at 2' by a portion 6a' of the mirror guide 6 at the position shown at 5'. After inserting the cassette tape 4 into the cassette holder 3, move the cassette holder 3 (lower left in the figure), the mirror 2 will move from the 2' position to the 2 position, and the metal plate 5 will move from the 5' position to the 5 position and move forward. The state of the cassette tape 4 can now be monitored from the right side in the figure.

In this conventionally configured cassette house,
The cassette holder 3 has a metal plate 5, and since it is necessary to attach the mirror guide 6 with double-sided tape or the like to slide the end of the mirror 2 onto the metal plate 5, the weight and cost increase. Also, when the cassette holder 3 is moved, the surface of the mirror 2 is touched by a part 6 of the mirror guide 6 on the sheet metal 5.
There was a risk that the surface of the mirror 2 would be scratched due to the sliding movement of the mirror 2 (as shown in 6a').

(iii) Disclosure of the invention The purpose of the invention is to overcome the above-mentioned conventional drawbacks, and by installing the mirror guide on the side of the cassette holder, reduce the cost and prevent the occurrence of mirror scratches from affecting the use. To provide a cassette house that can prevent such problems.

That is, the present invention includes a cassette house body,
A cassette house comprising a mirror rotatably mounted on the inner surface of the upper part of the cassette house body, and a cassette holder disposed within the cassette house so as to be movable horizontally and vertically and housing a cassette tape therein, The cassette holder has a U-shaped cross section that opens upward, and a mirror guide is installed on one side of the cassette holder at a position that can engage with the end of the mirror, and the cassette holder can be moved horizontally and vertically. In the cassette house, only the mirror guide is engaged with the mirror to rotate the mirror.

(iv) Best Mode for Carrying Out the Invention Next, the present invention will be explained by way of an example with reference to the drawings. In FIG. 2, there is a mirror 12 mounted on the upper inner surface of the cassette house main body 11 so as to be rotatable in the direction of arrow A by means such as a hinge, and a cassette holder 13 is mounted below the mirror 12 so as to be rotatable in the direction of arrows B and C. possible. The cassette holder 13 has a U-shaped cross section that opens upward, and the side plate 1
3a and 13b. A mirror guide 16 extending in the longitudinal direction of the side plate 13a is attached to the upper inner surface of one side plate 13a. A cassette tape 14 is inserted inside the cassette holder 13. The mirror guide 16 has a smooth upper surface 16a, and slides on the side edge of the mirror 12 in this portion.

In use, when inserting the cassette tape 14 into the cassette house, the cassette holder 13 is at the upper position 13', the mirror guide 16 is at the position shown at 16', and the mirror 12 is pushed up horizontally to the position shown at 12'. It is in. After inserting the cassette tape 14 into the cassette holder 13, move the cassette holder 13 (lower left in the figure) and the mirror 12
moves from the position shown at 12' to the position shown at 12, and the status of the remaining amount of the cassette tape 14 can be monitored from the front (right side in the figure). When moving the cassette holder 13 and operating the mirror 12 using the mirror guide 16, the mirror guide 16 is attached to the side plate 13a of the cassette holder 13, so the sliding portion of the mirror 12 with the mirror guide 16 is Since this is done only at the ends, there is almost no chance of scratches occurring on the mirror 12 during sliding, and even if they do occur, they will be limited to only the extreme periphery of the mirror 12 and will not affect the use at all.

Furthermore, the present invention does not require the conventional sheet metal 5 and the mirror guide 6 to be attached thereon with double-sided tape, so it is advantageous in terms of weight and cost.

(v) Effects of the invention Since the invention is configured as described above,
This produces the effects described below.

The mirror can be formed so as to maintain a state in which the cassette can be monitored well at all times, and the occurrence of scratches on the mirror can be prevented so that it does not affect the use of the mirror.

Furthermore, the configuration is simple and costs can be reduced.
