FIG. 1 is a transparent perspective view of a data processing device that is an embodiment of the present invention.

This data processing device includes a CRTl with a screen size of 5 inches x 9 inches, a daisy wheel type printer, 2. It is equipped with a floppy disk drive device 4 and also has a separate keyboard (not shown). These CRTs
l. Daisy wheel printer 2. The floppy disk drive device 4 and the like are housed and built into the chassis 10.

The chassis 10 has a pair of substantially triangular lower right chassis 12 and lower left chassis 14. The lower right chassis 12 stands almost vertically, and has a side plate 16 having an upper edge that descends toward the rear, a front side plate 18 that bulges outward from the front line of the side plate 16, and a front side plate 18 that extends outward from the lower edge of the side plate 16. A fixed plate 20 bent into a single character shape, a protrusion 22 in which a part of the side plate 16 is bent outward at right angles from the middle below the side plate 16, and a protrusion part 22 bent inward at right angles from the lower edge of the front side plate 18. A back plate 26 is provided, which is bent inward from the upper edge of the side plate 16 and forms an inclined surface at right angles. Through holes 22a and 2 are provided approximately in the center of the protruding portion 22 and the leg plate 24, respectively.
4a, and a through hole 20a is also bored at the rear of the fixing plate 20.

The lower left chassis 14 stands approximately parallel to the lower right chassis 12, has a back plate 28 having the same slope as the back plate 26 of the lower right chassis 12, and has a symmetrical shape with the lower right chassis 12. .

Further, an upper right chassis 30 is placed on the back plate 26 of the lower right chassis 12, and the upper right chassis 30 has a side plate 3 erected approximately parallel to the side plate 16 of the lower right chassis 12.
2, a fixing plate 30 bent inward from the lower edge of the side plate 32 into a single character shape, and an engaging portion 36 formed by bending a part of the side plate 32 outward at right angles. A left upper chassis 38 having a symmetrical shape with the right upper chassis 30 is placed on the left lower chassis 14, facing the right upper chassis 30.

Furthermore, it also includes a back plate 26 of the lower right chassis 12 and a shielding plate 40 made of a silicon steel plate located at the lower left.

This shielding plate 40 is formed with a bulging convex portion 42 according to the shape of the CRTI.

The shielding plate 40 is fixed to the lower right chassis 12 together with the fixing plate 34 of the upper right chassis 30 by screws 44, and is fixed to the back plate 26 of the lower left chassis 14 together with the left upper chassis 38 by screws 46. Further, the upper rear end of the lower right chassis 12 and the lower rear end of the upper right chassis 30 are fixed by screws 48, and the upper rear end of the lower left chassis 14 and the lower rear end of the upper left chassis 38 are fixed by screws 50. There is. The shielding plate 40 may not be inserted between the lower right chassis 12 and the upper right chassis 30, but may be fixed to the back plate 26 of the lower right chassis 12, or may be fixed to the fixing plate 34 of the upper right chassis 30. It may be fixed.

The chassis 10 formed in this manner is fixed to the lower cover 60 that covers the bottom of the chassis 10 by inserting screws (not shown) into the respective through holes 20a, 22a, and 24a of the lower right chassis 12. The lower left chassis 14 is similarly fixed to the lower cover 60 with screws (not shown). Further, a square frame-shaped front panel 62 is tilted backward and fixed to the front side plate 18 of the lower right chassis 12 with two screws 64, and a front panel 62 is similarly fixed to the lower left chassis 14. There is. This reinforces the strength, and the CRTl and floppy disk drive device 4 are mounted side by side on the front panel 62, and the screen of the CRTl is tilted rearward. This angle of inclination is preferably between 10 and 3
The angle is 0 degrees, and in this example, it is approximately 18 degrees.

On the other hand, in the upper right chassis 30, a vibration isolating rubber (not shown) is inserted into the engaging portion 36, and the lower cover 6 is inserted through the vibration isolating rubber.
0, and the left upper chassis 38 is similarly placed on the lower cover 60. This upper right chassis 30
A daisy-wheel printer 2 is installed between the upper left chassis 38 and the upper left chassis 38. This daisy-wheel type printer 2 includes a carriage 66 that is slidably supported between the lower chassis 30 and 38, a type wheel 67 placed on the carriage 66, and a type of type on the type wheel 67. It is comprised of a printing handle 768 that hits the back surface, a ribbon cassette (not shown) that stores a printing ribbon, and the like. Furthermore, an upper cover 70 that covers the entire chassis 10 is placed over the daisy-wheel type printer 2.

In the data processing device of this embodiment configured in this way, the lower right chassis 12 has a fixing plate 20 and a back plate 26 which are each bent at right angles, and the back plate 26 is provided so as to be inclined rearward. Therefore, the fixed plate 20 and the back plate 26 move diagonally, resulting in high rigidity. Since the upper right chassis 30 is placed on this inclined back plate 26, the length of the chassis 10 can be reduced.
The height can also be lowered. The same applies to the lower left chassis 14 and the upper left chassis 38. Incidentally, this inclination angle is preferably 10 to 30 degrees, and in this embodiment, it is about 24 degrees.
degree. This is because if the angle of inclination is smaller than 10 degrees, the height of the chassis 10 will increase, and if it is larger than 30 degrees, the daisy-wheel printer 2 will be tilted too much and the print quality will deteriorate.

Furthermore, a shielding plate 40 provided across the lower right chassis 12 and the lower left chassis 14 prevents leakage magnetic flux generated from a type selection motor, a carriage drive motor (not shown), etc. of the daisy-wheel printer 2 from flowing below the shielding plate 40. prevent leakage. Alternatively, a clip or the like accidentally dropped from the daisy-wheel printer 2 may be stored inside the lower cover 60 of the control board 72. Prevent it from falling onto the power supply board 74, etc. A hole 40a is bored in the approximate center of the shielding plate 40, and an arm can be inserted through the hole 40a to attach the control board 72. Harness processing of the power supply board 74 and the like can be performed.

After this harness processing is completed, the hole 40a is covered with a flat cable holder (not shown).

As described above, the data processing device of this embodiment has a pair of lower right and lower left chassis 12.1 that are erected approximately parallel to each other.
4, upper right and upper left chassis 30.38 resting on lower right and lower left chassis 12.14, and straddling both lower chassis 12.14 and lower chassis 12.14.
14 and a shielding plate 40 inserted between both lower chassis 30 and 38.

Therefore, according to the data processing apparatus, the chassis 10 has high rigidity, and even when the daisy-wheel printer 2 is driven, the chassis 10 does not shake and the print quality is not deteriorated. Furthermore, since the chassis 10 is small, the entire device can be made smaller. Furthermore, the shielding plate 40 prevents leakage magnetic flux from the type selection motor, carriage drive motor, etc. of the daisy-wheel printer 2 from affecting the CRTl and causing image fluctuation. Moreover, it prevents the user from accidentally touching the high voltage part of the CRTl, and also prevents the clip or the like from falling onto the control board 72, power supply board 74, etc.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments in any way, and it goes without saying that the present invention can be implemented in various forms without departing from the gist of the present invention.

Effects of the Invention As detailed above, according to the data processing device of the present invention,
The rigidity of the chassis is high, preventing the print quality of the daisy-wheel printer from deteriorating, and the device is more compact.

Also, due to magnetic flux leakage from the daisy-wheel type printer, C
This also has the effect that the RT image does not fluctuate.
