Further, in the figure, reference numeral 83 denotes a fixed disk 83 which fits into a disk-shaped groove formed by the fastening recess 79 and the fixed recess 82.

Next, the procedure for attaching the ball bearing 71 will be described.
As shown in FIG. 13, first, insert a compression spring 75 into each recess 78 of the upper case 20, place a ball bearing 71 on it, and cover the mounting plate 80 from above to mount the ball bearing 71 on the mounting plate 80. The mounting plate 80 is positioned in each of the windows 81, and the mounting plate 80 is fitted into the fitting groove 77 of the upper case 20 in that state. Next, the fixed disk 83 is fitted from above into the disk-shaped groove formed by the fastening recess 79 and the fixed recess 82, and the lower surface of the fixed disk 83 and the bottom surfaces of both recesses 79, 82 are bonded with an adhesive or a double-sided adhesive tape. From this, the compression spring 75, as shown in FIG.
Compressed between the ball bearing 71 and the bottom of the recess 78, the ball bearing 71 resiliently projects from the window 81 of the mounting plate 80.

On the other hand, the mounting structure of the ball bearing 72 mounted on the upper surface of the under case 21 is almost the same, but since it is not necessary to install an elastic spring in this, a part of the ball bearing fits in the recess 78 '. Hemispherical depression (3,15
Figure).

Incidentally, the mounting structure of the ball bearings 73, 74 arranged on the inner wall surfaces on the left and right of the storage space A is slightly different from the above-mentioned mounting structure, but since it is not a characteristic configuration, its explanation is omitted.

On the other hand, the appearance of the mobile case 3 will be described. An elongated paper insertion window 84 is provided laterally on the upper surface of the mobile case 3, that is, the front edge of the upper case 20, and the mobile case 3 is inserted through the paper insertion window 84.
A sheet can be inserted into the sheet insertion port 14 of the information equipment main body 2 housed inside (Fig. 10). Also, studs 85 are planted on both sides of the carrying case 3 so that both studs 85
The buckle portions 87, 87 at both ends of the shoulder belt 86 can be attached and detached (Fig. 4).

Further, in the auxiliary space B of the carrying case 3, a power source unit (not shown) such as a battery and a DC / DC converter is built in, and these are internally connected to the information equipment body 2 and related to the information equipment body 2. Then, on the left side of the carrying case 3,
7 As shown in Fig. 7, the removable lid 88 and switch 89
And a connector 90. Further, as shown in FIG. 18, a mounting bracket 91 and a jack 92 are provided on the right side surface of the carrying case 3.

On the other hand, the soft case 4 has a box shape slightly larger than the carrying case 3 as shown in FIGS. 1, 19 and 20, and the opening front surface 94 can be opened and closed by a lid 93 extending downward from the upper end thereof. The surface fastener 95 enables the lid 93 to be locked in the closed state. Further, a transparent window 96 is provided on the lid 93 so that the information equipment main body 2 can be seen, and the transparent window 96 is horizontally long and narrow so as to face the paper discharge port 13 and the paper insertion opening 14 at the lower stage of the information equipment main body 2, respectively. Slits 97 and 98 are opened. The soft case 4 has a notch 99 from which the stud 85 of the mobile case 3 projects, a switch 89 and a connector 90, a mounting bracket 91 and a jack.
Various openings 100 to 102 which 92 respectively face are cut out, and a mounting piece 10 for inserting an accessory device (not shown) is provided on the left side surface thereof.
3 is sewn in a ring shape.

Next, the procedure of using the assembled portable case 3 having the above-described configuration will be described. First, to mount the information device body 2 in the portable case 3, as shown in FIG.
Align it with the opening 16 of the carrying case 3 in the rearward direction, and then push it inward.

At that time, the ball bearings 71 to 74 arranged on the four inner wall surfaces of the storage space A are brought into sliding contact with the outer surface of the information equipment body 2 to reduce the frictional resistance between them. Further, the ball bearings 71, 73 arranged on the upper surface and the left inner surface elastically contact the outer surface of the information device body 2 by the action of the compression springs 75, 76, so that the information device body 2 is inserted slightly obliquely. The information device body 2 can be smoothly inserted even if there is a dimensional error.

Then, when the information device main body 2 is pushed in, as shown in FIG. 5, the rear surface abuts on the front surface of the slide frame 29, and the link mechanisms 26, 27 are pushed in via the slide frame 29. This allows
The link mechanisms 26 and 27 are shortened against the urging force of the tension springs 30 and 31, and the lock cam 57 on the upper surface of the information device body 2 is locked by the locking piece 61.
(Fig. 12 (a)).

When the information device body 2 is pushed further in here, as shown in FIG. 12 (b), the locking piece 61 is pushed by the lock cam 57 and the through hole 65 provided in the width direction of the guide groove 59. Move to the right along with, and the lock cam 57 slides beside it. At this time, the screw 64 fixing the locking piece 61 is attached to the slide plate.
It moves along the inclined hole 63 of the 60 and pushes the slide plate 60 against the biasing force of the coil spring 67, so if the lock cam 57 slips through, the locking piece 61 is pushed by the biasing force of the coil spring 67. Go through the through hole 65
It engages 57 and then prevents the return (Fig. 12 (c)).

As a result, the information device main body 2 resists the force that pushes back the information device main body 2 due to the contracting force of the tension springs 30 and 31 of the link mechanisms 26 and 27, and is stored in the storage space A of the mobile case 3. It is locked in the retracted storage position (Fig. 10). At this storage position, the information equipment main body 2 is connected to the power supply unit built in the auxiliary space B, and the paper insertion opening 14 on the upper surface of the front edge thereof is connected.
Then, the paper insertion windows 84 of the carrying case 3 are aligned with each other, and the paper can be inserted into the paper insertion opening 14 of the information device body 2 through the paper insertion window 84.

In this way, if the information device main body 2 is stored in the mobile case 3, it is further stored in the soft case 4.
Shoulder belt to stud 85 of carrying case 3
With the buckle part 87 of 86 attached, the shoulder belt 86 can be lowered and carried freely (Figs. 19, 20).

On the other hand, even if the information device main body 2 is stored in the soft case 4, paper can be inserted and ejected through both slits 97 and 98 of the lid 93, and if the lid 93 is opened, the information device main body 2 Operation of operation switches 7 and 8 and upper paper ejection port 1
The use of 2 is also possible.

Further, when the information device main body 2 is taken out from the mobile case 3 and maintenance such as replenishment or replacement of consumables is performed, the slide switch 62 on the top surface of the mobile case 3 may be pushed inward.

When the slide switch 62 is pushed in, the slide plate 60 is pushed against the urging force of the coil spring 67, and the locking piece
61 moves to the right along the through hole 65 and disengages from the lock cam 57.

Therefore, the locked state is released, and the information device main body 2
The link mechanisms 26 and 27 are extended by the contracting force of the tension springs 30 and 31, and are pushed out through the slide frame 29.

At this time, the air damper 18 'acts and the information device main body 2
Is quietly extruded. That is, in the extension stroke of the link mechanisms 26 and 27, the piston 48 is pushed into the cylinder 47, the air in the piston 48 is exhausted from the orifice 50, and the braking force acts.

Moreover, in the shortening stroke of the piston 48, the piston 48 is pushed into the cylinder 47 having a reduced diameter along the inclined inner wall surface 51 of the cylinder 47, so that the braking force thereof gradually increases. The reason why the braking force is increased in this way is due to the use of the pantograph-shaped link mechanisms 26 and 27.

That is, since the extension degree of the link mechanisms 26 and 27 gradually increases with respect to the contracting stroke of the tension springs 30 and 31,
When the cylinder 47 uses a simple cylindrical air damper, the braking force is almost constant, so that the pushing speed of the information equipment body 2 is gradually accelerated, and the information equipment body 2 is blown. There is a risk of coming out.

Therefore, in this embodiment, by providing the inclined inner wall surface 51 in the cylinder 47 and reducing the inner diameter of the cylinder 47 toward the head end, the braking force is intentionally increased in the shortening stroke of the piston 48. I am doing it.

On the contrary, in the extension process of the piston 48, the braking force is gradually decreased, but the information device main body 2 is pushed by hand in this process, so that the pushing force can be gradually reduced. That is, the reaction force of the tension springs 30 and 31 increases as the information device main body 2 is pushed further in.
It can be canceled by reducing the braking force of. The damper
If a check valve is provided at 18 ', the braking force can be prevented from being exerted during the shortening stroke of the piston 48.

In this way, the information device main body 2 includes the tension springs 30 and 31 and the damper 1
The link mechanism 2 is pushed out quietly by the action of 8 ', and at the position where the tip of the link shaft 39 hits the front end of the sliding groove 55 and stops.
The extension of 6,27 stops, and at this stop position, the front part of the information equipment body 2 partially projects from the opening 16 of the carrying case 3 (FIG. 4).

When the release button 6 on the side of the information equipment body 2 is operated in this protruding state, the front panel 5 can be removed to the front, and maintenance such as replenishment or replacement of consumables can be performed.
Further, by pulling out the information equipment main body 2 from this position, the information equipment main body 2 can be taken out.

In the embodiment shown in the drawings, the spring force of the tension springs 30 and 31 is set to be relatively weak so that the opening portion of the carrying case 3 is opened.
Even if the slide switch 62 is inadvertently operated in a state in which 16 is directed upward, that is, in an upright state when being carried by the shoulder belt 86, the information device main body 2 can pop out from the opening 16 of the mobile case 3. It is designed so that it does not exist and is safe when carried.

Further, in this embodiment, the contracting force of the tension springs 30 and 31 is used to push the information device main body 2 from the back through the link mechanisms 26 and 27. The information device body 2 may be pulled or pulled out by directly acting on the body 2.

Further, the lock means 19 is configured to release the locked state by manually operating the slide switch 62, but the lock state can be released by simply pressing the front surface of the information device main body 2 in the stored state. A latch mechanism may be used.

<Effect of the Invention> As described above, according to the present invention, the information device main body automatically protrudes from the opening of the carrying case by releasing the locked state of the locking means, which frequently occurs. Maintenance such as replenishment or replacement of consumables can be easily performed. Further, when the information device main body is housed in the storage space of the rigid mobile case from the opening, it can be connected to the power supply unit built in the auxiliary space of the mobile case and operated. Further, by accommodating the portable case in the soft case, the information equipment body is doubly protected by the hard portable case and the soft case. Even if the portable case is housed in the soft case, it is possible to insert the paper from the outside of the soft case into the paper insertion opening of the information device main body or to eject the paper outside from the paper ejection opening of the information equipment main body.
