Abstract

PURPOSE:To shift the operation from the 1st reduced state to the expanded 2nd state through a simple operation by holding and engaging the 1st main body loading a cassette magazine with the 2nd main body slide for unloading the cassette magazine by a lock member. CONSTITUTION:In the 1st state, the lock claw 3a of the lock member 3 locks a lock pin 9 fixed on the 2nd main body. When the projection part 3b of the lock member 3 is operated counterclockwise due to force overcoming energizing force applied clockwise, the lock between the lock claw 3a and the lock pin 9 is unlocked, and the 2nd main body 2 automatically slides and moves from the 1st main body 1 according to the energizing force in the direction of an arrow (a). Through this operation the 2nd state can be obtained, and a head 6 and a pinch roller 7 are separated from the cassette magazine 4, which becomes detachable. The contact of the lock pin 9 with the tilting part 3c of the lock member 3 abuts and turns the lock member, and automatically locks the lock pin 9.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a portable type small and lightweight cassette tape recorder.

Conventional technology In recent years, the size and weight of cassette and tape recorders has become even more remarkable, and some have a telescoping mechanism that shrinks when a cassette magazine is not installed and expands when a cassette magazine is installed, depending on the presence or absence of a sumo magazine. .

An example of a conventional telescoping cassette/soto tape recorder will be described below with reference to the drawings.

FIGS. 6 and 6 show the structure of a conventional telescopic cassette tape recorder. In FIG. 6, 12 is a first body into which the cassette magazine 4 is mounted, and 13 is a second body slidably held by the first body 12. 6
is capstan, 6 is head/socket, 7 is pinch roller, 8
are reels, each of which is connected to the first body 12.
is equipped with.

The operation of the conventional example configured as described above will be explained below. Figure 5 is a skein.

The first state is shown in which the magazine 4 is not attached.

FIG. 6 shows the state of the 23rd page with the cassette/soto magazine 4 attached, and in FIG.
3 is obtained by sliding and extending the cassette magazine 4 in the direction of the arrow A using a positioning mechanism that allows the cassette magazine 4 to be attached and detached. In this state, each mode is obtained by operating each operation button (not shown). FIG. 7 shows the movement of the spatula 6 when the recording/playback mode is selected in the second state shown in FIG. 6, and is separated from the cassette magazine 4 for attachment/detachment as shown by the solid line. cassette magazine 4 during playback or recording, as shown by the dotted line.
It comes into contact with the tape 11 inside.

Problems to be Solved by the Invention However, with the above configuration, the transition operation from the first state to the second state required when attaching and detaching the cassette magazine must always be performed using both hands. However, as shown in FIG. 7, the cassette magazine is removed by a dimension l for the head (the same applies to the pinch roller, not shown) to come into contact with and separate from the tape 11 in the cassette magazine 4. There was a problem in that when it was installed, the size had to be larger than when it was not installed.

In view of the problem mentioned above, the present invention improves the telescopic operability when attaching and detaching a cassette magazine, and also reduces the size when the cassette magazine is attached in the same way as when it is not attached, so that the portability of the magazine is not impaired. The present invention provides a cassette tape recorder that can perform

Means for Solving the Problems In order to solve the above problems, the telescopic cassette tape recorder of the present invention has a first cassette tape recorder for mounting a cassette magazine.
a second body that includes a head and a pinch roller and is slidably held on the first body, and a locking member that positions and holds the second body and the first body. It is something that

The present invention has the structure described above, eliminates the dimension e when the cassette magazine is installed, and makes it into a reduced first state regardless of the presence or absence of a 1-cassette magazine, and the installation and removal of a 6-vane cassette magazine. The transition from the first state to the second state, which is sometimes required, is easily possible without using both hands by engaging the mouth/ink member with the first body and the second body.

Embodiment Hereinafter, a case and foot table recorder according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows the first state of the present invention, in which numeral 1 denotes a first main body into which a cassette magazine 4 is attached, and a capstan 5.
and a reel 8, respectively. A second body 2 is slidably held on the first body 1, is provided with a head 6 and a pinch roller 7, and is always urged in the direction of arrow A. Reference numeral 3 denotes a locking member rotatably held on the first body 1 by a rotation shaft 10, and
'' - is constantly biased clockwise (in the direction of arrow A) so as to lock the lock pin 9 fixed at . FIG. 2 shows a second state in which the second main body 2 is slid from the first main body 1 at the position 1 where the case/foot magazine 4 can be attached and detached.

FIG. 3 shows an enlarged view of the locking member 3 in the first state, and FIG. 4 shows an enlarged view of the locking member 3 when changing from the second state to the first state again.

The operation will be explained below using FIGS. 1 to 4.

First, as shown in FIG. 3, in the first state shown in FIG. 1, the lock claw 3a of the lock member 3 locks the lock pin 9 fixed on the second main body. Next, the protrusion 3b of the locking member 3 is moved counterclockwise (arrow B) by a force that overcomes the biasing force applied in the clockwise direction (arrow A direction).
direction), the aforementioned lock claw 3a and lock pin 9 are unlocked, and the second body 2 automatically slides away from the first body 1 according to the urging force in the direction of arrow A. . Through this operation, the second state shown in FIG.
The cassette magazine 4 can be detached from the cassette magazine. After attaching and detaching the cassette magazine, as shown in FIG. 4, when the second main body 2 is slid in the direction of arrow A with a force that overcomes the urging force,
Due to the contact between the opening 71 and the inclined portion 3C of the locking member 3, the locking portion 3 contacts and rotates, and the locking pin 9 automatically closes.
Section 11-. By doing so, the first state shown in FIG. 1 is returned again. In this state, each mode can be obtained by operating each operation button (not shown).

Note that the effects shown in the embodiment can be similarly obtained by interlocking with a cassette lid (not shown) that is rotatably held by the first main body 1.

Here, the structure is designed to simplify the transition operation from the first state to the second state, but by changing the direction of the biasing force of the second main body 2, the transition from the second state to the first state is possible. It is also possible to simplify the transition operation.

According to the present embodiment, the first body into which the cassette magazine is attached and the second body which is slidable for attaching and detaching the cassette magazine are held together by the locking member, as described in ``Effects of the Invention''. The transition from the contracted first state to the extended second state can be made by simply operating the locking member with one hand, and the head and pinch roller can be used to attach and detach the cassette magazine. By providing it on the side of the second main body that allows the head and pinch roller to slide, the operation of separating the head and pinch roller from the cassette magazine and the operation of extending the set for attaching and detaching the cassette magazine are unified, which is different from the conventional example. It is possible to reduce the size of the head and pinch roller during use, which was a problem, and to reduce the size of the head and pinch roller.
It becomes possible to always maintain the reduced first state regardless of the unattached state, and this has great effects such as excellent operability and portability of the set.
