BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic tape device for reading / writing data from / to a magnetic tape.
More specifically, the first invention relates to a magnetic tape device comprising a printed circuit board and an FPC connected to the printed circuit board via a connector, and the second invention is a decorative panel arranged on the front side. In addition, the present invention relates to a magnetic tape device in which a hole for a display unit and an operation unit and a hole for inserting a cartridge are formed.

In recent years, there has been a strong demand for downsizing and cost reduction of magnetic tape devices, and accordingly, there is a demand for magnetic tape devices having excellent workability and capable of responding to downsizing.

[0003]

2. Description of the Related Art In many cases, a magnetic tape device has an external power source, and is usually provided separately from the main body of the device. In the magnetic tape device, a plurality of printed circuit boards are arranged. In the magnetic tape device of the external power supply type, these printed circuit boards are connected by a flat cable or the like.

For example, as shown in FIG. 9, a printed circuit board 1 provided with a controller (circuit) for controlling the entire apparatus and a printed circuit board 2 provided with a circuit for reading data are an upper part and a lower part of the device. , And these are connected to the FP via lockable connectors 3 and 4.
It is connected at C5.

Here, connectors with locks are used as the connectors 3 and 4 because the printed circuit boards 1 and 2 are fixed to the apparatus main body, and then the FPC 5 is mounted on the printed circuit boards 1 and 2 via the connectors 3 and 4. This is because there is a risk that the FPC 5 will come off due to vibration or the like because it is attached and the FPC 5 is supported by the printed boards 1 and 2. The mechanical unit 6 in FIG. 9 is a mechanical component that records / reproduces data on / from the magnetic tape while winding the magnetic tape pulled out from the cartridge.

Since an external power supply type magnetic tape device is troublesome to handle when moving, it is desired to realize an integrated magnetic tape device having a built-in power supply. As described above, a plurality of printed circuit boards are arranged in the magnetic tape device, and in order to incorporate the power supply in this configuration, the power supply is arranged adjacent to the mechanical section 6.

In the magnetic tape device, the casing parts other than the front panel, that is, the top plate, the bottom plate, the side plates and the back plate are
The front panel is made of a resin decorative panel, although it is made of sheet metal (metal plate). For this reason, the front panel is provided with measures against radiated noise that removes radiated noise that goes out of the device from circuits inside the device, and measures against electrostatic discharge that prevents static electricity from entering the device from outside the device. There is a need.

Therefore, conventionally, as shown in FIG. 10, conductive coating is applied to the back surface of the resin decorative panel 7 to form a conductive metal film (hatched portion in the drawing). Further, the decorative panel 7 is provided with a printed circuit board 10 on which a display unit 8 and an operating unit 9 are mounted, and a cartridge insertion port 11 and a lattice opening 12 for cooling.
Therefore, an insert screw for screwing the printed circuit board 10 or the like is fixed to the decorative panel 7 in advance, and the printed circuit board 10 or the like is assembled using the insert screw.

[0009]

In the conventional structure in which the printed circuit board is fixed to the apparatus body and then the FPC is attached to the printed circuit board through the connector, when a plurality of FPCs are connected to one printed circuit board, the printed circuit board is fixed to the FPC. The plurality of FPC connectors thus formed and the plurality of board connectors fixed to the printed circuit board have to be connected one by one, resulting in poor workability.

In particular, the printed circuit board of the magnetic tape device is
It may be replaced at the time of testing or maintenance, and with the conventional configuration,
When replacing the printed circuit board, first remove the FPC connectors one by one, replace the old printed circuit board with a new printed circuit board, and then again replace the plurality of FPC connectors one by one with the circuit board connector of the new printed circuit board. Since it has to be connected, it takes time and effort to replace it, and the workability at the time of replacement is poor.

Further, in the conventional structure, a connector with a lock is used to prevent the connector between the printed circuit board and the FPC from coming off due to vibration or the like. The space occupied by the connector inside becomes large, which is against the miniaturization.

Further, in the conventional structure in which the back surface of the resin-made decorative panel is conductively coated in order to prevent radiated radio noise and electrostatic discharge, not only the shielding effect is insufficient due to the thin metal film. When conducting the conductive coating, it is necessary to perform a masking treatment so that the coating does not adhere to the portion that will be the exterior surface, and the workability during manufacturing is poor. Moreover, since the display window and the operation switch of the display unit are provided near the printed circuit board on which the display unit and the operation unit are mounted, the masking process here is extremely troublesome. Workability is also poor in this respect.

Also, regarding the mounting of the insert screw for fixing the printed circuit board or the like to the decorative panel,
It is a manual work and the workability is poor. Furthermore, in the conventional configuration, since the resin decorative panel is used, the mechanical strength of the lattice opening for cooling is not sufficient, and it is necessary to take measures such as increasing the thickness of the decorative panel. Despite the thin membrane, the front panel is not necessarily thin and cannot be miniaturized.

The above-mentioned deterioration of workability at the time of manufacturing and testing / adjustment is one of the causes of an increase in manufacturing cost and maintenance cost. The present invention has been made in view of the above problems, and an object thereof is a magnetic tape device which is excellent in workability at the time of manufacturing or at the time of test / adjustment and which enables cost reduction, and can also be downsized. It is to realize a magnetic tape device.

The present invention is not limited to the connection of a particular FPC and a printed circuit board.
