Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a magnetic recording/reproducing apparatus using a cassette tape magazine.

Conventional structure and problems The cassette tape magazine storage section of a magnetic recording and reproducing device that uses a cassette tape magazine has been known to be of a rotating type or a sliding type, but in both cases, the magnetic recording and reproducing device The size of the main body is the same regardless of whether a cassette tape magazine is stored or not. On the other hand, in this type of field, where the market demand for excellent portability has become stronger as the size and weight have become smaller and lighter in recent years, there has been a problem in that the conventional method has reached its limit in size reduction.

OBJECTS OF THE INVENTION In order to solve the above-mentioned conventional problems, it is an object of the present invention to provide a magnetic recording and reproducing device which can be reduced in size when a cassette tape magazine is not used, and which can provide excellent portability. purpose.

Structure of the Invention In order to achieve the above object, the present invention provides a magnetic recording/reproducing device main body having first and second sliding guides on the side surfaces thereof, and a magnetic recording/reproducing device main body that is provided with first and second sliding guides in a state of engagement with the first sliding guide. a cassette tape magazine holder which is slidably held by the second sliding guide and which rotatably holds the cassette tape magazine holder; When the cassette tape magazine is not housed and held in the cassette tape magazine holder, the cassette tape magazine holder and the slide case are slidably moved by the first and second sliding guides, and the entire magnetic recording and reproducing apparatus expands and contracts. It is configured as follows. That is, the cassette tape magazine holder and the slide case slide in the extension direction from the main body of the magnetic recording/reproducing apparatus, and the cassette tape magazine holder is placed at a position where the cassette tape magazine can be attached to the main body of the magnetic recording/reproducing apparatus. The cassette tape magazine can be freely rotated, and by rotating it, the cassette tape magazine can be held in the cassette tape magazine holder, and the cassette tape magazine can be mounted on the main body of the magnetic recording/reproducing apparatus. As described above, the present invention improves portability by having a configuration in which the cassette tape magazine is contracted when not in use and expanded when in use, depending on whether or not the cassette tape magazine is used.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 7, the cassette tape magazine holder 1 has a first sliding groove 1a on at least one side surface thereof, and an L-shaped control arm 1.
b, a control shaft 1C that protrudes from the tip of the control arm 1b and controls the amount of rotation of the cassette tape magazine holder 1, and a rotation hole 1d on both sides of the cassette tape magazine holder 1 that serves as the center of rotation. A cassette tape magazine holding section 1e for holding a cassette tape magazine 4 is provided.
The slide case 2 has second sliding grooves 2a on both sides thereof and the cassette tape magazine holder 1.
A rotating shaft 2b rotatably holds the control arm 1b and a control arm sliding portion 2c on which the control arm 1b and the control shaft 1c rotate and slide. The magnetic recording/reproducing device main body 3 has a first sliding guide 3a that engages and slides with the first sliding groove 1a, and a first sliding guide 3a that engages with the second sliding groove 2a and is always in a sliding state. Second sliding guide 3b
, a third sliding guide 3c that slides and guides the control shaft 1c, and a control guide 3d that limits the movement range due to rotation of the control shaft 1c, and also includes a reel shaft 8, a capstan shaft 7, It is equipped with a pinch roller 6 and a magnetic head 5.

1, 2, and 3, the method of mounting the cassette tape magazine 4 will be explained. In FIG. 1, the cassette tape magazine 4 is not mounted. Here, as shown in Fig. 2, the cassette tape magazine holder 1 and the slide case 2 are
When the cassette tape magazine 4 is extended from the magnetic recording/reproducing apparatus main body 3 in the direction of arrow A in the drawing to a position where it can be attached to the magnetic recording/reproducing apparatus main body 3, in this state, the first sliding groove 1
At the same time as the sliding movement between the control shaft 1c and the first sliding guide 3a is released, the control shaft 1c and the third sliding guide 3c
The sliding state between the two is also released. This makes it possible for the cassette tape magazine holder 1 to rotate in the direction of arrow B as shown in FIG.
The control shaft 1c can be rotated until it comes into contact with the upper surface of the control guide 3d. By rotating the cassette tape magazine holder 1 to the above-mentioned state, the cassette tape magazine 4 can be held by the cassette tape magazine holder 1. Of course, when the cassette tape magazine holder 1 is rotated, the control shaft 1c comes into contact with the side surface of the sliding guide 3d, so that the cassette tape magazine holder 1 and the slide case 2 cannot slide in the direction of arrow c. It has become a state.

Next, when the cassette tape magazine holder 1 is closed while holding the cassette tape magazine 4, the state shown in FIG. Functions are obtained by performing each operation.

Next, in the reverse procedure to the above, the cassette tape magazine 4 is removed from the cassette tape magazine holder 1 in the state shown in FIG. 3, the cassette tape magazine holder 1 is closed, and the The cassette tape magazine holder 1 and slide case 2 can be slid and returned to the state shown in FIG. 1. Of course, in the state shown in FIG. 1, the first sliding guide 3a and the first sliding groove 1a are engaged and sliding, so the cassette tape magazine holder 1 cannot rotate. It is becoming.

Effects of the Invention As described above, according to the present invention, the overall size of the magnetic recording/reproducing device is different between the state in which a cassette tape magazine is not installed and the state in which it is installed, and in particular, the size is different when a cassette tape magazine is not installed. It has become possible to achieve considerable miniaturization and improve portability, which has a significant effect.
