Abstract

PURPOSE:To make a device smaller at least when a cassette tape magazine is not used and obtain excellent portability by constituting in such a way that a cassette tape magazine holder and slide case is made freely slidable by the 1st, 2nd and 3rd sliding guides and overall magnetic recorder and reproducer can expand or contract. CONSTITUTION:When a cassette tape magazine holder 1 and a slide case 2 are extended to such a position that a cassette tape magazine 4 can be mounted on a main body of a recorder and reproducer 3 in an arrow A direction from the main body, both sliding motions of the 1st slide groove 1a and 1st slide guide 3a are released, and at the same time, sliding condition of a control shaft 1c and the 3rd slide guide 3c is also released. This allows the magazine holder 1 to rotate in the direction of an arrow B until the control shaft 1c comes to abut on the upper face of a control guide 3d. By rotating the holder 1, the magazine 4 can be held in the holder 1.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic recording and reproducing apparatus using a cassette tape magazine.

Conventional configurations and their problems Conventionally, the cassette tape magazine storage section in magnetic recording and reproducing devices has been known to be of the rotating type and the dispensing type. This is the same regardless of whether the tape magazine is stored or not.

On the other hand, in this type of field, where the market demand for medical portability has become stronger as miniaturization and weight reduction have progressed in recent years, there has been a problem in that the conventional method has reached its limit in miniaturization.

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

Structure of the Invention In order to achieve the above objects, the present invention has the following features: The main body of the magnetic recording/reproducing device is equipped with a third sliding guide and a control guide on its side, and a control shaft protruding from a sumo wrestler soto tape magazine holding part and a control arm, and the first and third sliding guides The cassette tape magazine is slidably held by the magnetic recording and reproducing device main body, and is slidably held by the first and third sliding guides at a position where the cassette tape magazine can be attached to the magnetic recording and reproducing device main body. It is released and becomes freely rotatable, and as a result of this rotation, the control guide and the control shaft control the first. A cassette tape magazine holder that prevents mh by a 30th finger guide, and a slide case that rotatably holds the cassette tape magazine holder and is slidably held by the second sliding guide. and when the cassette tape magazine is not stored and held in the cassette tape magazine holder, the first. Second. The third sliding guide allows the force sensor magazine holder and the slide case to freely slide, thereby allowing the entire magnetic recording and reproducing device to expand and contract. When it is not attached, it can be made smaller than when it is attached, which has the advantage of improving portability.

Description of an Actual Gun Example Hereinafter, an example of the present invention will be explained based on the drawings. 1st
In FIGS. 7 to 7, the cassette tape magazine holder 1 has a first sliding groove 1 on at least one side surface thereof.
a, an L-shaped control arm 1b, and a sumo wrestler tape magazine holder 1 protruding from the tip of this control arm 1b.
The cassette tape magazine holder 1 is provided with a control shaft 1c for controlling the zero rotation horse, a rotation hole 1d on both sides of the cassette tape magazine holder 1 serving as the rotation center, and a cassette chip magazine holding portion 1e for holding the cassette tape magazine 4. .

The slide case 2 has a second finger m2a on both sides thereof.
and a rotation shaft 2b that rotatably holds the cassette tape magazine holder 1, and the control arm 1b and flr.
Control arm bracket/moving part 2C where the control shaft 1C rotates/moves
Equipped with. The magnetic recording/reproducing device main body 3 includes a first sliding guide 3a that engages with and slides on the first cage I moving bird 1a;
a second sliding guide 3b that engages with the second sliding groove 2a and is in the n-time working order; a third finger guide 3C that slides and guides the control shaft 1C; It is equipped with a control guide 3d that limits the movement range due to the rotation of 1C, and also includes a reel I\llll8. Capstan shaft7. It includes a pinch roller 6 and a magnetic head 6.

Now, to explain the method of mounting the cassette tape magazine 4 in FIG. 1, FIG. 2, and FIG. 3, FIG. 1 shows a state in which the cassette tape magazine 4 is not mounted. Here, as shown in FIG. 2, the cassette tape magazine holder 1
When the slide case 2 is extended from the magnetic recording/reproducing apparatus main body 3 in the direction of the arrow in the drawing to a position where the cassette tape magazine 4 can be attached to the magnetic recording/reproducing apparatus main body 3, in this state, the first At the same time as the finger movement between the sliding groove 1a and the first sliding guide 3a is released, the sliding state between the control shaft 1C and the third sliding guide 3C is also released. As a result, as shown in FIG. 3, the cassette tape magazine holder 1 can be rotated in the direction of arrow B, and can be rotated by the control shaft 1C coming into contact with the upper surface of the control guide 3d. Then, by rotating the magazine holder 1 in the above-mentioned state, the cassette tape magazine 4
can be held in 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 control guide 3d, so the cassette tape magazine holder 1 and the slide case 2 cannot move in the direction of the arrow C. It is in a state. Next, when the cassette tape magazine holder 1 is closed while holding the sumo wrestler's throat tape magazine 4, the state shown in FIG. figure)
These functions can be obtained by performing the respective operations.

Next, in the reverse procedure to the above, remove the cassette tape magazine 4 from the cassette tape magazine holder 1 in the state shown in FIG. 3, close the cassette tape magazine holder 1, and move in the opposite direction to the arrow. It becomes possible to move the cassette tape magazine holder 1 and the slide case 2 in batches, and it is possible to return them to the p-th position shown in FIG.

Of course, in the glued state of FIG. 1, the first swing guide 3a and the first sliding groove 1a are in the engaged and sliding state, so the cassette tape magazine holder 1 cannot rotate. It is in a state.

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. This makes it possible to achieve considerable miniaturization and improve portability. Furthermore, the cassette magazine holder and slide case are stable because they do not rotate in the contracted state and do not extend any further in the extended state due to the control shaft at the end of the control arm and the third sliding guide and control guide in the device body. The structure can be made as follows.
