Abstract

PURPOSE:To prevent a cassette tape from displaying due to a shock, etc., even at the time of housing the analog compact cassette tape and to stabilize the reproducing/recording operation. CONSTITUTION:The main body 6 of a holder is provided with 1st and 2nd cassette holders 7, 8 to house an ACC1 or a DCC at the both sides while guiding them, and spring parts 9 to press a magnetic tape housing part 1f of the cassette tapes are provided in the 1st and 2nd cassette holders 7, 8. Since the pressing force exerted by the spring parts 9 are set by taking the DCC as reference, the pressing force is weakened when the ACC1 is loaded. For this countermeasure, control parts 10 projecting integrally with the main body 6 of holder are formed on two places, and a thickness part 1e of ACC1 is made so as to be supported by the control parts 10 when the ACC1 is loaded on the main body 6 of holder. Then, the ACC1 is positioned by the control parts 10 when it is loaded on the main body 6 of holder.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette tape recorder applicable to both digital cassette tapes and analog cassette tapes having different thicknesses of magnetic tape storage portions.

[0002]

2. Description of the Related Art In recent years, audio equipment has tended toward digital audio, and due to technological development, a high fidelity cassette tape recorder has been developed by digital recording and digital reproduction. -Two schemes of DAT have been proposed. Especially SD
Since the AT is a fixed head, the structure of the head and tape cassette is similar to that of the analog type cassette tape recorder, which is widely used at present. Therefore, one cassette tape recorder can record and reproduce both analog and digital signals. It is expected that commercialization will be possible.

Conventionally, analog type cassette tapes (hereinafter,
The ACC (abbreviated as ACC) has a structure as shown in FIG. In the figure, 1 is an ACC, which is composed of a reel hub portion 1b for winding the magnetic tape 1a, a main body portion 1c accommodating the magnetic tape 1a, and a thick portion 1e in which a portion having a window portion 1d is thickened. The magnetic tape storage portions 1f located on both sides of the main body portion 1c are thick portions 1
It is formed thinner than e (see dimension A).

FIG. 6 shows a currently proposed digital type cassette tape (hereinafter abbreviated as DCC), which is DCC2.
Has a substantially flat surface, and a reel hub portion 2b for winding the magnetic tape 2a and a main body portion 2 accommodating the magnetic tape 2a.
c and a shutter 2e which covers the opening 2d when not in use and slides in the direction of travel of the magnetic tape 2a or in the opposite direction when it is used, and the thickness (size B) of the magnetic tape housing 2f is ACC1. Magnetic tape storage 1
It is formed thicker than the thickness of f (dimension A).

On the other hand, the currently proposed cassette tape recorder is a tape storage unit 1 for ACC1 and DCC2.
Although the thicknesses of f and 2f are different, the holder means for accommodating both tape cassettes has the same size, and ACC is placed there.
By mounting a cassette tape of 1 or DCC2, both signals can be recorded / reproduced.

[0006]

However, in the above proposed cassette tape recorder, when the DCC2 is stored in the holder means that can store both the ACC1 and the DCC1, the cassette tape is unlikely to float due to an external impact. However, when accommodating the thin ACC1 of the magnetic tape accommodating portion 1f, it is easy for floating to occur due to an external impact.
There was a problem that it adversely affected the recording.

The present invention solves the above-mentioned conventional problems and can be applied to both DCC and ACC cassette tapes, and prevents the cassette tapes from being lifted due to a shock or the like even when the ACCs are housed, and the reproducing / recording operation is performed. It is an object of the present invention to provide a cassette tape recorder that can stabilize the temperature.

[0008]

In order to achieve the above-mentioned object, the present invention has a holder for accommodating two kinds of cassette tapes, DCC and ACC, in a holder means for accommodating an analog type cassette tape. Is formed to regulate the

[0009]

In the above structure, when the ACC is stored in the holder means, the restricting portion provided on the holder means is
Since the position of the thick portion of the CC is regulated, it is possible to prevent the floating due to the impact from the outside.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In this example,
The same components as those described above are designated by the same reference numerals.

In FIG. 3, reference numeral 3 denotes a cassette holder support, which is provided on both sides of the substrate 4 and rotatably supports the holder body 6 by means of a shaft portion 5.

As shown in FIGS. 1 and 2, the holder body 6 has ACC1 (see FIG. 1) or DCC on both sides thereof.
The first and second cassette holders 7 and 8 for storing while guiding 2 (see FIG. 2) are provided. The first and second cassette holders 7 and 8 have a magnetic tape storage unit 1 for cassette tapes.
It has a spring portion 9 for biasing f and 2f, a magnetic head 11 and a pinch roller 13.

As shown in FIG. 4, since the thickness (A dimension) of the magnetic tape storage section 1f of the ACC1 is thinner than the thickness (B dimension) of the magnetic tape storage section 2f of the DCC2, the ACC1 is mounted on the holder body 6. In this state, the gap between the first and second cassette holders 7 and 8 and the magnetic tape housing portion 1f is (C dimension), and the gap when the DCC 2 is mounted on the holder body 6 is (D dimension). Therefore, the size of the C dimension and the D dimension is (C> D), but the spring portion 9
Thus, the urging force that urges the magnetic tape storage portions 1f and 2f becomes weak when the ACC1 is mounted. As a countermeasure against this, the restricting portion 10 protruding integrally with the holder body 6 is
It is formed in several places, and when the ACC1 is mounted on the holder body 6, the thick portion 1e of the ACC1 is regulated by the regulating portion 10.

As described above, according to the cassette tape recorder of the embodiment, when the ACC1 is mounted on the holder body 6, it is regulated by the regulating portion 10, and when the DCC2 is mounted, the magnetic tape storage portion 2f is urged by the spring portion 9. In addition, since the cassette holders 7 and 8 regulate it, even if two kinds of cassette tapes, ACC1 or DCC2, are attached to the holder body 6, it is possible to prevent the occurrence of floating due to an external impact.

[0015]

As is apparent from the above-described embodiments, the cassette tape recorder of the present invention is such that the holder means is formed with the restriction portion for restricting the thick portion when the analog cassette tape is stored. By doing DC
Although it is C compatible, it can be loaded with two types of conventional ACC cassette tapes, and prevents the cassette tapes from floating due to shock or the like even when the ACCs are stored, thus stabilizing the playback / recording operation.
