DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette mounting device for recording and reproducing video signals and the like on a magnetic tape, for example, a video movie.

[0002]

2. Description of the Related Art In recent years, video movies have been required to be smaller and lighter, and the cassette mounting device, which is a component thereof, has also been required to be smaller and lighter.

[0003] A conventional cassette mounting apparatus will be described below. FIG. 4 is a perspective view of the cassette mounting / dismounting position of the conventional cassette mounting apparatus, and FIG. 5 is a sectional view of the conventional cassette mounting apparatus when the cassette is down. In FIG. 4, 101 is a cassette, and 102 is a cassette holder which detachably holds the cassette 101. Reference numerals 108 and 109 denote shafts for adjusting the left and right transfer of the cassette holder 102 and the stand 105, respectively. Reference numeral 103 denotes an arm a, and 104 denotes an arm b. One end is rotatably held and the other end is slidably held. The arms are rotatably engaged with each other at substantially the center. 105 is an arm a1
This is a stand having a center of rotation 03 and a sliding groove for the arm b104. 106 is an arm a103 and an arm b104
And biases the cassette holder 102 from the cassette down position shown in FIG. 5 to the cassette attaching / detaching position direction shown in FIG. Reference numeral 107 denotes a pressing spring having one end fixed to the cassette holder 102.

[0004] The operation of the conventional cassette mounting apparatus configured as described above will be described below. First, in the state shown in FIG. 4, the cassette 101 is inserted into the cassette holder 102 in the direction of arrow A and manually moved to the cassette down position in FIG. In this position, the cassette 101 engages with the positioning pin 110 of the apparatus main body, and the pressing spring 10
At 7, it is pressed in the direction of arrow B and is mounted and fixed at a predetermined position.

[0005]

However, in the above-mentioned conventional configuration, when the whole is downsized in the case of a product such as a video movie, for example, the proportion of the entire projection area of the cassette mounting device becomes large, It is desirable to arrange operation switches for recording, reproduction, stop, etc. on the upper surface of the cassette holder 102.
2 moves up and down almost in parallel with the vertical direction.
The switches arranged on the upper surface of the
There was a problem that it was extremely difficult to connect.
Therefore, trying to remedy this problem,
It is necessary to constitute a mechanism of the wiring unit separately from the holder 102, and when it is used as a product, there is a problem that the number of parts is increased and the weight is large.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a cassette mounting device in which operation switches and the like can be arranged on a projection surface of the cassette mounting device with a simple configuration.

[0007]

In order to achieve this object, a cassette mounting apparatus according to the present invention comprises a cassette holder for housing a cassette having a magnetic tape housed therein, and a cassette holder rotatably supported by the apparatus body. A first member rotatably supported at one end by the first member and a second member engaged at the other end with a cam groove provided in the apparatus main body. The cassette holder is rotatably connected to the first member and the cam groove provided in the first member is also engaged with the first member to rotate the first member so that the cassette can be detached from the cassette. It has a configuration to move to the second position to be performed.

[0008]

With this configuration, the first position and the second position of the cassette holder (cassette) can be moved by the rotation of the first member, and the operation provided on the projection surface of the first member can be performed.
It is possible to configure a cassette mounting apparatus in which the connection between the switch and the like and the apparatus main body can be extremely easily performed, and it is possible to reduce the number of parts and to reduce the size and weight.

[0009]

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a cassette, 2 is a cassette holder, 3 is a top plate, 4 is an arm, 5 is a stand, and 6 is an up spring. The cassette holder 2 is rotatably supported by the arm 4 at the support 2a, and slidably engages with the cam groove 3c of the top plate 3 at the support 2b. The top plate 3 is rotatably supported by a stand 5 about a support 3a. The arm 4 is rotatably supported by the top plate 3 about the support 4a. Sliding groove 5a
And are slidably engaged. The up spring 6 is locked by the top plate 3 and the support 3b, and is rotatably locked by the arm 4 and the support 4c.

The operation of an embodiment of the cassette mounting apparatus constructed as described above will be described with reference to FIGS. 2 and 3 in addition to FIG. First, as shown in FIG.
Into the cassette holder 2 in the direction of arrow A,
When manually pressed from the direction, as shown in FIG. 2, the top plate 3 rotates about the support portion 3a, the arm 4 rotates about the support portion 4a disposed at one end thereof, and is disposed at the other end. Since the support 4b slides along the slide groove 5a, the support 2a moves in the direction of arrow B. At this time, the support portion 2b provided at the other end of the cassette holder 2 is
Slides along the cam groove 3c and moves in the direction of arrow B, so that the cassette holder 2 moves in parallel in the direction of arrow B.
Further, as the top plate 3 is rotated, the cassette 1 is transferred to the cassette down position shown in FIG. 3, and is engaged with the positioning pins 7 of the apparatus main body to be mounted at a predetermined position. At this position, the top plate 3 is locked at a predetermined position on the apparatus main body by a lock mechanism (not shown). At this time,
The arm 4 is urged in the direction of arrow C by the up spring 6 around the support portion 4a, and the support portion 4b arranged at the other end of the arm is configured not to be restrained by the sliding groove 5a. Transmitted to the cassette holder 2 via the support portion 2a,
The upper surface portion 2c of the cassette holder 2 abuts on the upper surface of the cassette 1 and urges the cassette 1 in a direction for fixing the cassette 1 to the apparatus main body. When the lock mechanism is released, the top plate 3 rotates in the direction opposite to the arrow D by the urging force of the up spring 6, and the movement causes the cassette holder 2 to move in the direction opposite to the arrow B in parallel via the arm 4. Return to the position shown in FIG.

As described above, according to the present embodiment, the movement of the cassette holder 2 is controlled by the rotation of the top plate 3 and the movement of the arm 4.
By performing through, Ru can be biased in a direction to fix the cassette 1 into the apparatus body of the cassette holder 2 by the urging force of the up spring 6 in the cassette-down position. Ma
In addition, the top plate 3 rotates about the support portion 3a.
In the vicinity of the support portion 3a, a connection line from the apparatus main body (shown in FIG.
By arranging the not), even extremely is connected by arranging the operating scan <br/> acme switch (not shown) of which part on the projection surface of the top plate 3
Easily.

[0013]

As described above, according to the present invention, the operation switch and the like can be easily arranged on the projection surface of the top plate by moving the cassette holder through the rotation of the top plate and the arm. Yes, with cassette
An excellent cassette mounting device capable of reducing the number of parts of the mounting device and reducing the size and weight can be realized.
