Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a magnetic tape device. The magnetic tape device includes a magnetic recording / reproducing device and a magnetic reproducing device.

[0002]

[Prior art]

 Conventionally, in this type of magnetic tape device, as shown in FIGS. 3 and 4, a tape deck main body 2 having a recording and / or reproducing section is mounted on one side of a device housing 1 and the rear side thereof is mounted. A tuner 3 and an input / output jack 4 are arranged on the printed wiring board 5 which is located on the other side of the device housing 1 and which is planarly arranged on the bottom of the device housing 1. , Pulse transformer 6 and other parts are mounted. The device casing 1 has a box-like shape including a bottom portion 1A, both side wall portions 1B and 1B ', a back panel portion 1C and a front wall portion 1E, and a front panel 7 is attached to the front surface thereof. .

On the other hand, the frame 2A of the tape deck main body 2 is located on the side wall portion 1B side, and is provided with a mounting portion 2B for mounting on the bottom portion 1A of the apparatus housing, and also at a rear edge portion thereof. , And the mounting portion 2C, respectively. Then, the mounting portion 2B is mounted on the bottom portion 1A by means such as screwing, and the deck mounting portion 1D is formed on the bottom portion 1A of the apparatus housing 1 in correspondence with the mounting portion 2C of the tape deck body 2. It is formed in an upright state, and the deck body 2 is attached and supported by means such as screwing.

[0004]

[Problems to be solved by the device]

 In such a configuration, a considerable part of the load of the tape deck body 2 is loaded on the bottom portion 1A of the device housing 1 via the deck mounting portion 1D. However, as indicated by the dimension A, the deck mounting portion 1D is considerably separated from the back panel portion 1C. Therefore, when vibration is applied to the device housing during transportation of the magnetic tape device, the inertia of the deck main body is increased. Due to the mass, when a bending stress is generated in the chassis bottom portion 1A, it undergoes a considerable amplitude motion. Therefore, unless the thickness of the chassis forming the device housing 1 is sufficiently secured and the rigidity thereof is not increased, the deck main body 2 and the printed wiring board 5 that are assembled into one body as a whole need to be mounted on these. There is a risk of mechanical damage to parts. However, this hinders the weight reduction of the entire magnetic tape device.

This invention was made based on the above circumstances, and by devising the layout of parts such as the tuner, the device housing was drastically arranged so as to have the minimum depth necessary for housing the deck body. By shortening this, by forming the deck mounting part standing upright from the bottom of the equipment case in the position close to the back panel of the equipment case, vibration can be eliminated without supplementing the chassis thickness. On the other hand, it is intended to provide a magnetic tape device which has sufficient rigidity and is devised so as not to mechanically damage necessary parts due to the above vibration.

[0006]

[Means for Solving the Problems]

 Therefore, the present invention is directed to a device housing having a front wall portion, a side wall portion, a back panel portion, and a bottom portion, a printed wiring board attached to the bottom portion of the device housing, and a back panel portion at the bottom portion of the device housing. A deck mounting part standing upright at a position close to the tape deck, a tape deck body supported by at least the front wall part and the deck mounting part, and a fixing for fixing the mounting part of the tape deck body to the deck mounting part. And means are provided.

Further, an apparatus casing having a front wall portion, a side wall portion, a back panel portion and a bottom portion, a printed wiring board attached to the bottom portion of the equipment casing, a bottom portion of the apparatus casing and a back panel portion. And a tape deck body supported by at least the front wall portion and the deck attachment portion, and a fixing means for fixing the attachment portion of the tape deck body to the deck attachment portion. It is characterized by

Furthermore, in such a magnetic tape device, the fixing means is screwed.

[0009]

[Action]

 Therefore, even if the deck mounting part of the device housing is formed upright on the bottom part, even if it receives vertical vibration from the outside, it is possible to avoid the influence of the bending stress applied to the bottom part. Even if the thickness of the device housing is not supplemented, sufficient rigidity can be ensured in the state where the tape deck body is supported and fixed to the device housing.

【Example】

 An embodiment of the present invention will be specifically described below with reference to FIGS. 1 and 2. The components shown in the conventional description are shown by using the same reference numerals, and the description thereof will be omitted in the following embodiments. In particular, the features of this invention are the configuration of the apparatus housing 1 and the arrangement of necessary parts. That is, the device housing 1 has a structure that is shortened in the front-rear direction so that the tape deck main body 2 has a minimum depth necessary for accommodating the tape deck main body 2. It is mounted on the inside of the device casing 1 at a position laterally away from the tape deck body 2.

The tuner 3 is of a partition type, and high-frequency noise generated from a switch circuit incorporated in the printed wiring board 5 and a pulse transformer 6 mounted on the printed wiring board 5 is a tape. This prevents influence on other circuits on the deck body 2 and the printed wiring board 5.

As shown in FIG. 2, the tape deck main body 2 is a deck in which a front portion thereof is erected on a front wall 1E of the device housing 1 and a rear mounting portion 2C thereof is erected on a bottom portion 1A of the device housing 1. The mounting portion 1C is supported by the mounting portion 1D, and the mounting portion 2C is fixed to the deck mounting portion 1D by means such as screwing. The deck mounting portion 1D is formed adjacent to the back panel portion 1C which continuously stands up on the chassis bottom portion 1A, and particularly, in this embodiment, is formed continuously with the back panel portion 1C.

With this configuration, when the magnetic tape device is transported, a vertical vibration force applied from the outside causes a strong vibration force to the deck body having a particularly large mass, and a considerable part of the force is generated. Is added to the deck mounting portion 1D, but since the deck mounting portion 1D is not separated from the back panel portion 1C, almost no bending stress is generated in the bottom portion 1A.

[0014]

[Effect of device]

 As described in detail above, this invention is installed at least at a position close to the front wall portion and the bottom back panel portion of the device housing, or the deck mounting portion connected to the bottom portion and the back panel portion. Since the tape deck body is supported and the mounting portion of the tape deck body is fixed to the deck mounting portion, sufficient rigidity against vibration can be secured and necessary parts can be secured without supplementing the thickness of the device housing. In addition, it is possible to obtain the practical effect of not giving mechanical damage due to the vibration.
