Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a cassette type tape recorder which is ultra-compact and convenient to carry.

(B) Conventional technology In the field of cassette-type tape recorders, competition for miniaturization has intensified in recent years. However, in the cassette type tape recorder, since it is necessary to store the cassette in the cassette storage chamber of the cabinet, the size cannot be made slightly smaller than the cassette. However, recently, as shown in FIGS. 1 to 4, a front cabinet (1) in which a tape drive mechanism and the like are incorporated, and a lid (2) are attached so as to be openable and closable, and a rear surface of the front cabinet (1). By constructing the tape recorder body with the rear cabinet (3) slidably attached to the opening, the tape cassette (4)
The tape recorder, which is miniaturized to the same size as the cassette case that stores the
It is already on sale with a model number of -20 type. In the unused state where the tape cassette is not installed in the cabinet, the tape recorder is reduced to a size substantially the same as the cassette case as shown in FIG. 1, but when the tape cassette (4) is installed, the tape recorder is shown in FIG. As shown in FIG. 3, the rear cabinet (3) is pulled out rearward, and then the lid (2) is opened and the tape cassette (4) is mounted in the cassette storage chamber (5) as shown in FIG. Therefore, in the state where the tape cassette (4) is mounted and used in the cassette storage chamber (5), it is larger than the cassette case as shown in FIG. In the above system, the tape cassette (4) is attached to the cassette storage chamber (5) or the magnetic head or the like does not get in the way when it is taken out. 5) is unfolded, the tape cassette (4) is stored in the cassette storage chamber (5), and then the slide base provided in the front cabinet (1) is slid to slide the tape cassette (4).
This is because the magnetic head or the pinch roller is inserted through the windows (6) and (6) and the magnetic head or the pinch roller is brought into contact with the tape, which requires a distance for sliding the slide base. The effect of making it about the same size as the case is halved.

(C) Object of the Invention Therefore, the present invention provides a cassette tape recorder which is not only in the unused state where the tape cassette is not mounted in the cassette storage chamber but also when the tape cassette is mounted in the cassette storage chamber and used. It is provided.

(D) Configuration of the invention The present invention is a cabinet provided with a tape drive configuration,
A main lid body that is openably and closably attached to the cabinet and has a front opening, and a slide base that is provided with at least a magnetic head and is slidably provided in the cabinet, and covers the front opening of the main lid body. The present invention relates to a cassette type tape recorder configured with a sub lid.

(E) Example A cassette type tape recorder of the present invention will be described below with reference to the drawings. As shown in FIG. 5 to FIG. 9, the tape recorder of the present invention includes a cabinet (11) having a step (10) formed at the front and a step (10) having a front surface (12) opened. Except for the box-shaped main lid (14) attached to the surface of the cabinet (11) so as to open and close so as to form the cassette storage chamber (13), and the stepped portion of the cabinet (11) ( 10) and a sub lid (15) for closing the front surface (12) of the main lid (14). The cabinet (11) has a motor, gears driven by the motor, and a capstan (16).
(16) and reel shafts (17), (17) and other tape drive mechanisms are built-in, and the pinch rollers (19) (19) are attached to the plane of the step (10) by the shafts (18) (18). Roller mounting metal fittings (20) (20) are rotatably mounted, and holes (21) (21) are drilled on the side surface of the step (10). Further, the tip end of the sub-lid body (15) is inserted through the holes (21) (21), and the long holes (22) (22) at the tip end are fitted to the pins (23) (23) on the cabinet (11). A main slide base (24) slidably attached to the cabinet (11) by fitting is attached. Further, the main slide base (24) has pins (25) on the step (10).
By fitting the long holes (26) and (26) into the (25), the auxiliary slide base (27) slidably mounted on the cabinet (11) as well as the main slide base (24) has a spring (28). It is connected. A magnetic head (29) for recording and reproducing is attached to the sub slide base (27). The pinch roller fittings (20) (20) and the magnetic head (29) are extremely small, and most of them are inserted through the windows (31) (31) of the tape cassette (30). .

The cassette-type tape recorder of the present invention has the above-described structure. To play the tape, the main lid base (24) is slid so that the main lid base (24) is slid. 14) is opened at the front (Fig. 6, Fig. 11)
Figure). When the main lid (14) is lifted and opened in such a state,
Since the cassette storage chamber (13) formed between the main lid (14) and the cabinet (11) is exposed, the tape cassette (which is to be reproduced in the cassette storage chamber (13) by hand ( 30) Insert. As the main slide base (24) is moved forward, the magnetic head (29) is also moved forward together with the sub slide base (27), and the pinch roller mounting brackets (20) (20) also have the pins (32) (32) sub. The slide base (27) is rotated clockwise or counterclockwise, and the pinch roller fittings (20) (20) are also moved forward. Therefore, since the tape cassette (30) is not disturbed by the magnetic head (29) and the pinch rollers (19) (19), the hub (33) (33) of the tape cassette (30) can be pushed down by inserting it downward. The tape cassette (30) is fitted in the reel shafts (17) (17) and is mounted in the cassette storage chamber (13). After that, if you push in the sub lid (15),
The main and sub slide bases (24) (27) are again slid in the original direction. At this time, the magnetic head (29) and the pinch roller metal fittings (20) (20) are formed small and are inserted through the windows (31) (31) of the tape cassette (30), so the main and sub slide bases (24) (27) advances to its original position without being obstructed by the magnetic head (29) and the pinch roller metal fittings (20) (20), and the sub lid (15) closes the opening of the main lid (14). . In this state, the pinch rollers (19) (19) are positioned at or near the capstans (16) (16), and the magnetic head (29) is also lightly contacted with or near the tape ( (Fig. 13). Next, when the play button (34) is pressed, the magnetic head (29) advances as it is or slightly to come into full contact with the tape, and the reel shaft (17) and capstan (16) on the right side are rotated by the motor. Therefore, the tape is run by the capstan (16) and the pinch roller (19), reproduced by the magnetic head (29), and wound on the hub (33). When the tape has run to the end, this is detected, this time the motor is rotated in reverse and the left capstan (16) and hub (33) are rotated, the tape is run in the opposite direction, and the reverse direction. Play. When fast-forwarding or fast-rewinding the tape, pressing the fast-forward button or fast-rewind button causes the pinch rollers (19) (19) and the magnetic head (29) to move as they are or to increase the load. Is reduced.

In the above, the slide base is the main slide base (24)
And a sub slide base (27), magnetic head (29)
Since the sub-slide base (27) with the attached is more independent from the main slide base (24) attached to the sub-lid (15) and is connected with the springs (28) (28), the tape cassette (30) can be attached and detached. There is little concern that the azimuth will be misaligned even after repeating, and since the pinch rollers (19) (19) are mounted on the main cabinet (11), the pinch rollers (19) (1)
The stability of 9) is good, and it is possible to eliminate the influence of the slide on the tape running.

However, in a tape recorder where the tape running property is not so important, as shown in FIG. 14, the pinch roller mounting bracket (2) is attached to the shaft (35) (35) on the sub slide base (27).
0) (20) rotatably, or rotate the pinch roller mounting brackets (20) (20) with the shafts (36) (36) on the main slide base (24) as shown in FIG. It may be movably mounted and the pinch rollers (19) (19) may be provided on the main slide base (24).

Further, when there is no fear of azimuth deviation too much, in order to simplify the mechanism, the slide base is formed only by the main slide base (37) as shown in Fig. 16, and the magnetic head (29) and pinch roller mounting bracket are attached. (35) (35)
Both of them may be provided on the main slide base (37).

(F) Effect of the Invention As described above, the cassette type tape recorder of the present invention is
The lid body for covering the surface of the cabinet provided with the tape drive mechanism is constituted by a box-shaped main lid body having a front opening and a sub lid body closing the front opening of the main lid body. Since the slide base which is slidably attached to the cabinet and has at least a magnetic head is provided, the sub-lid body is moved forward when the tape cassette is attached to the main lid body and the cassette storage chamber formed on the surface of the cabinet. When the tape cassette is moved, the slide base slides and the magnetic head and the pinch roller retract and do not interfere, so that the tape cassette can be easily mounted in the cassette storage chamber. Moreover, when the sub-lid is pushed after mounting the tape cassette, the slide base is slid in the original direction, the magnetic head and the pinch roller are also moved in the tape cassette direction, and it is inserted into the tape cassette and the sub-lid is returned to its original position. At the same time, the magnetic head and the pinch roller are returned to the operating position or the substantially operating position. Therefore, since the space for sliding the slide base after mounting the tape cassette is not required, the cabinet can be made smaller by that amount, and the magnetic head can be lightly contacted with the tape when the tape cassette is mounted. It is possible to reduce the stroke for setting the operation position for reproduction or the like, or to eliminate it altogether.
