Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention [Field of Industrial Application] The present invention relates to a data processing device equipped with a chassis that accommodates at least a CRT and a daisy wheel type printer.

[Conventional technology]

Conventionally, data processing devices equipped with a CRT and a printer had the CRT and thermal printer attached to a chassis that also served as a cover. Alternatively, divide the inside of a box-shaped chassis into each room and install a CRT in each room.
There were also known ones that housed devices such as printers and thermal printers.

[Problem that the invention seeks to solve]

However, with these conventional data processing devices, there were no particular problems if the printer was a thermal printer, but if the printer was a daisy wheel type printer, the chassis was weak and the chassis would vibrate, resulting in poor print quality. There was a problem that the size was getting bigger. Furthermore, there was also the problem that the image on the CRT 1 fluctuated due to magnetic flux leakage from the daisy wheel type printer.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems and to provide a data processing device equipped with a chassis suitable for a daisy wheel printer.

[Effect]

The data processing device of the present invention having the above configuration includes:
A lower chassis for storing a CRT, which has a fixing part on the lower edge, stores the CRT, and an upper chassis for a daisy wheel type printer is placed on an inclined surface.
Further, a shielding plate is fixed across the slope. Therefore, the chassis is highly rigid and compact, and prevents leakage of magnetic flux from the daisy wheel printer.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings. 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 CRT 1 of 5 inches by 9 inches in screen size, a daisy wheel printer 2, a floppy disk drive device 4, and also has a separate keyboard (not shown). These CRT 1, daisy wheel type printer 2, floppy disk drive device 4, etc. are housed and incorporated in a 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 is installed almost vertically,
A side plate 16 having an upper edge that descends toward the rear, a front side plate 18 that is bent outward from the front edge of the side plate 16, and a fixed plate 20 that is bent outward from the lower edge of the side plate 16 in an L-shape. , a protruding part 22 in which a part of the side plate 16 is bent at a right angle outward from the middle of the lower part of the side plate 16, a leg plate 24 bent inward at a right angle from the lower edge of the front side plate 18, and an upper edge of the side plate 16. and a back plate 26 forming an inclined surface bent inward at right angles. Through holes 22a and 24a are formed in the substantially central portions of the protruding portion 22 and the leg plate 24, respectively, and a through hole 20a is also formed at the rear of the fixed plate 20. Note that the lower left chassis 14 is erected approximately parallel to the lower right chassis 12, and the lower right chassis 12
A back plate 28 is formed having the same slope as the back plate 26 of , and is symmetrical to the right lower 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 32 that stands approximately parallel to the side plate 16 of the lower right chassis 12, and A fixed plate 30 bent inward from the lower edge into an L shape, and a side plate 3
2 is bent outward at right angles to form an engaging portion 36. 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 is inserted between the lower right chassis 12 and the upper right chassis 30 and the lower left chassis 14 and the upper left chassis 38, spanning the back plate 26 of the lower right chassis 12 and the back plate 28 of the lower left chassis 14. It also includes a shielding plate 40 made of silicon steel plate. This shielding plate 40 is formed with a bulging convex portion 42 according to the shape of the CRT 1.

The shielding plate 40 is the fixed plate 3 of the upper right chassis 30
4 and is fixed to the lower right chassis 12 by a screw 44, and is fixed to the upper left chassis 38 by a screw 46.
It is fixed to the back plate 26 of the left lower chassis 14 by. 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. Note that the shielding plate 40 is not inserted between the lower right chassis 12 and the upper right chassis 30, but is inserted between the back plate 2 of the lower right chassis 12.
6, or the upper right chassis 30
It may be fixed to the fixing plate 34 of.

The chassis 10 thus formed is fixed to the lower cover 60 that covers the bottom of the chassis 10 by inserting screws (not shown) into the through holes 20a, 22a, 24a of the lower right chassis 12. The left lower chassis 14 is similarly fixed to the lower cover 60 with screws (not shown). Also, lower right chassis 1
A square frame-shaped front panel 62 is tilted rearward and fixed to the front side plate 18 of No. 2 with two screws 64, and the front panel 62 is similarly fixed to the left lower chassis 14. As a result, the strength is reinforced, the CRT 1 and the floppy disk drive device 4 are mounted side by side on the front panel 62, and the screen of the CRT 1 is tilted rearward. This angle of inclination is preferably between 10 and 30 degrees, in this example approximately 18 degrees.

On the other hand, in the right upper chassis 30, a vibration isolating rubber (not shown) is inserted into the engaging portion 36, and the left upper chassis 38 is similarly placed on the lower cover 60. This upper right chassis is placed on the lower cover 60 via this vibration-proof rubber, and between the upper left chassis 38 and the daisy wheel type printer 2
is included. This daisy wheel type printer 2 is slidably supported by a platen 65 rotatably supported between the upper chassis 30 and 38, and a pair of guide bars (not shown) provided parallel to the platen 65. With the carriage 66,
It is composed of a type wheel 67 placed on the carriage 66, a print hammer 68 that hits the back side of the type on the type wheel 67, a ribbon cassette (not shown) containing a print 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 as described above, the lower right chassis 12 has a fixing plate 20 and a back plate 26, each of which is bent at a right angle.
6 is provided tilting backwards, so the fixing plate 20
and the back plate 26 are inclined and have high rigidity. Since the right upper chassis 30 is placed on this inclined back plate 26, the length and height of the chassis 10 can be reduced. The same applies to the lower left chassis 14 and the upper left chassis 38. Note that this inclination angle is preferably 10 to 30 degrees, and in this embodiment is about 24 degrees. This is because if the inclination angle is smaller than 10 degrees, the height of the chassis 10 will become high, and if it is larger than 30 degrees, the daisy wheel type printer 2 will be tilted too much and the print quality will deteriorate.

Further, the shielding plate 40, which is provided across the right lower chassis 12 and the left lower chassis 14, prevents leakage magnetic flux generated from a type selection motor and a carriage drive motor (not shown) of the daisy wheel printer 2 from flowing below the shielding plate 40. Prevent leakage. Moreover, clips, etc. that were accidentally dropped from between the daisy-wheel printers 2 were removed from the lower cover 6.
Control board 72 and power supply board 7 housed in 0
Prevent falling onto 4th grade. In addition, shielding plate 4
A hole 40a is bored approximately in the center of 0, and an arm can be inserted through this hole 40a to perform harness processing for the control board 72, power supply board 74, and the like.
After this harness processing is completed, the hole 40a is covered with a flat cable holder (not shown).

As mentioned above, the data processing device of this embodiment is
A pair of lower right and left chassis 12 and 14 erected approximately in parallel; upper right and left chassis 30 and 38 placed on the lower right and left chassis 12 and 14; and both lower chassis 12. , 14, and a shielding plate 40 inserted between both lower chassis 12, 14 and both lower chassis 30, 38.

Therefore, according to the data processing device, chassis 1
0 has high rigidity, and even when the daisy wheel type printer 2 is driven, the chassis 10 does not shake and the printing 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 CRT 1 and causing image fluctuation. Moreover, it prevents accidental touching of the high voltage part of the CRT 1, and prevents clips from touching the control board 72.
It also prevents it from falling onto the 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 chassis has high rigidity, and the print quality of the daisy wheel type printer is prevented from deteriorating.
Moreover, the device has the effect of being miniaturized.
Another advantage is that the image on the CRT does not fluctuate due to magnetic flux leakage from the daisy wheel printer.
