Description

  The present invention relates to an electronic device case that is used by mounting an IC card.

In an electronic device case that is used with a conventional IC card mounted, for example, in the case of a notebook personal computer case as an electronic device case disclosed in Patent Document 1, the IC card is inserted into the surface of the side wall of the case. The IC card insertion slot is provided, and an IC card holder is provided deeply into the case.
The depth of the IC card holder should be kept at the same dimensional position as the surface so that the rear end of the IC card does not protrude from the surface of the case side wall with the IC card mounted or at a position deeper than that. It is set to stop.
On the surface of the case side wall around the IC card insertion slot, there is formed a concave depression for operation for pushing out or pushing in the IC card or for picking and pulling it out.
JP 2001-331234 A ([0028] to [0031], FIGS. 1 to 4)

In the above notebook personal computer, when the IC card is mounted in the IC card holder, an IC card insertion slot for inserting the IC card is provided on the surface of the side wall of the case, and the rear end of the IC card Is kept at the same dimensional position as the surface so that it does not protrude from the surface of the case side wall, so there is little risk of dust entering the IC card holder from the IC card insertion slot, and the mounted IC There is also little risk of flying objects hitting the card.
Furthermore, it is also possible to form a concave depression for pushing out or pushing in the IC card on the surface of the case side wall around the IC card insertion slot as shown in FIG. Thin and relatively easy.

  Therefore, in the applicant company, the IC card insertion slot for inserting the IC card shown in the drawing of Patent Document 1 is used as another electronic device case, for example, the wide flat shown in FIG. The plurality of electronic devices with respect to the surface of the case of the level checker, which has an upward operation surface and on which a large number of electronic device elements (switches, input terminals, displays, etc.) for operating electronic devices are arranged. We tried to prepare for coexistence with equipment elements.

However, when an IC card insertion slot is installed on the upward surface of the level checker case as the electronic device case, the following problems occur.
As a first point, when an IC card insertion slot is provided on the upper surface of the level checker case and an IC card holder is provided deep inside, the dust on the upper surface of the level checker case is removed from the IC card insertion slot. Depress in. The dust causes a problem of causing contact failure between the terminals of the IC card and the terminals of the internal electronic circuit.
Second, when an IC card is mounted and an item is accidentally dropped from above the level checker case while the level checker is in use, if the item directly hits the upper end of the IC card, the IC card May be damaged.

Further, as a third point, the depth and width of the IC card insertion slot provided on the flat surface of the upper surface of the level checker case can be pushed out, pushed in with a finger, or pulled out. It is necessary to provide a concave depression for card operation.
In addition, since the depression is configured so that dust such as dust that has fallen into the depression can be swept out, a depression with a large exclusive area is inevitably required around the IC card insertion slot.
Therefore, the installation place of the IC card insertion slot is limited to a place where a depression with a large surface area for operation can be installed around the card insertion slot, and cannot be installed in the vicinity of the electronic device element. There was a problem that the degree of freedom in selecting the installation location of the insertion slot was limited.

Further, as a fourth point, when the IC card is mounted on the IC card mounting portion provided on the surface of the case, if the upper end of the IC card does not protrude from the upper surface of the level checker case, the depth dimension of the level checker ( The height dimension) requires the length of the card holder for inserting the IC card.
This raises the problem of increasing the depth of the level checker and increasing its size.
As described above, when the IC card insertion slot for inserting the IC card shown in the drawing of Patent Document 1 is applied to another electronic device case, the above four problems may occur. The configuration of the conventional IC card insertion slot cannot be applied to other electronic device cases.

An object of the present application is to provide an electronic device case in which an IC card can be detachably mounted.
Another object is to prevent dust from entering the IC card insertion slot provided on the surface of the electronic device case from the surroundings, and to protect the IC card mounted on the case from flying objects. Thus, an electronic device case is to be provided.
Another object of the present invention is to provide an electronic device case in which an IC card can be protected by attaching a protective cap and the attached state of the protective cap can be maintained.
Another object of the present invention is to provide an electronic device case in which an IC card can be detachably mounted so that the depth of the case can be reduced.
Other objects and advantages will be readily apparent from the drawings and the following description associated therewith.

  An electronic device case according to the present invention is provided on the surface of the above case in an electronic device case in which an IC card insertion opening is provided on the surface of the case for inserting an IC card with respect to an IC card holder provided in the case. A protective wall is installed around the IC card insertion slot in a standing state, and a concave part for IC card operation is formed at the upper part of the protective wall with a rising wall for preventing dust from entering below. The depth dimension of the IC card insertion hole in the IC card holder is such that, in the state in which the IC card is inserted, the upper end of the IC card is erected around the IC card insertion slot and the upper end surface of the wall. It is set so as to be located between the recesses.

The present invention includes an electronic device case, for example, a level checker case, and a level checker operating electronic device element (switch, input terminal, display, etc.) provided on the operation surface. ) Coexisting with IC card insertion slot 16
The configuration is such that a protective wall 20 is provided in a standing state around the IC card insertion slot 16 provided on the surface 2a of the case 1, and a concave portion 20b for operating the IC card is provided at an upper position of the protective wall 20. Since the rising wall 20e for preventing entry of dust remains below,
The first point is that even if there is dust or dirt on the upward wide flat surface 2a of the case, it is prevented from falling into the IC card holder 18 from the IC card insertion slot 16, and the terminals of the IC card 35 It has the feature of preventing poor contact between terminals with the internal electronic circuit.
Secondly, because of the above configuration, the card prevents the impact of the flying object from the side on the IC card 35, protects the electronic device in the electronic device case 1, and prevents the failure of the electronic device. There is.
These have the effect on use which can be used with few electrical and mechanical troubles and accidents of electronic equipment.

In addition, since the present invention is configured as described above, when the protective cap 23 is attached to the IC card insertion slot 16,
First, when the card is mounted, the protective cap 23 completely prevents dust on the upper surface 2a of the electronic device case and dust from above from falling into the IC card holder 18 from the IC card insertion slot 16. Thus, there is a feature that prevents poor contact between the terminals of the IC card 35 and the internal electronic circuit. Further, the protective cap 23 has an advantage that the electronic device in the electronic device case 1 is protected by preventing an impact on the IC card 35 due to flying objects from above.
As a second point, the protective wall 20 having the dust intrusion preventing effect has a feature of facilitating fixing such as prevention of lateral displacement of the protective cap 23 at the same time.

In the present invention, even when the IC card insertion slot 16 is provided on the flat surface of the electronic device case upper surface 2a, as described above, the protective wall 20 is provided around the IC card insertion slot 16 in a standing state. Therefore, the occupied area is limited to a very narrow range, and there is an advantage that the arrangement of electronic device elements (switches, input terminals, displays, etc.) around the IC card insertion slot 16 is not adversely affected.
This means that when selecting the installation location of the IC card insertion slot 16, a narrow gap is provided close to other electronic device elements even on the upper surface of the electronic device case having many electronic device elements such as a level checker case. There is also a feature that can be selected, and the degree of freedom in selecting the installation location of the IC card insertion slot 16 is not limited, and there is an effect accompanied by a design advantage that facilitates the layout design of the IC card insertion slot 16.

  Further, the present invention provides a wall in which the upper end 36 of the IC card is erected around the IC card insertion slot 16 when the IC card 35 is inserted in the depth dimension of the insertion hole 17 of the IC card 35 as described above. Since it is set so as to be located between the upper end surface 20a of the 20 and the recess 20b, the depth dimension of the electronic device case is set by the dimension corresponding to the length dimension of the upper end 36 of the IC card from the case surface. It can be shortened. This has the advantage that it can contribute to reducing the thickness of the depth dimension of the electronic device case.

Hereinafter, drawings showing embodiments of the present invention will be described. FIG. 1 to FIG. 5 illustrate a level checker case showing an example of an electronic device case.
In the case 1 of the electronic device described above, a large number of electronic device elements (switches, input terminals, displays for operating the functions of the electronic device are known for the upward surface 2a of the surface member 2 shown in FIG. Etc.) are arranged. The portion 3 indicated by the alternate long and short dash line on the lower side of the surface member 2 in FIG. 2 is formed of an arbitrary hard material such as a synthetic resin material or a metal material in the same manner as the surface member 2. The presence of the case main body 3 formed separately by the forming means and then detachably attached to the surface member 2 is shown, and an arbitrary electronic device is built in the internal accommodation space.
The electronic device elements arranged on the surface 2a of the surface member 2 are exemplarily shown. For example, 4, 5, 6, 7, 8, 9 and so on are sequentially displayed, input terminal, output terminal, and buzzer sound. It indicates the presence of holes, charging terminals, and external power input terminals.

   Next, a known IC card holder 18 is provided in the case 1 of the electronic device. The holder 18 is configured to be able to correspond to any known card of an IC card 35 (for example, an SD card, a memory stick, a smart media, etc. known as a trade name). In addition, the IC card 35 that is inserted corresponding to the type of the IC card 35 to be used, such as a well-known push-in mechanism introduced in the above-mentioned Patent Document 1, is held in the IC card. A mechanism enabling the opening of 35 is incorporated.

  Reference numeral 19 shown in FIGS. 2 and 4 denotes a circuit board, which is made of an insulating material as is well known, and necessary electronic circuits are arranged on both sides thereof. The circuit board 19 uses a connecting portion 19a (for example, a bolt connecting hole) provided on the circuit board 19 and an arbitrary portion of the surface member 2 (for example, a concave portion 19b, a fastening portion 15). On the other hand, it is integrally connected. Further, the holder 18 is mechanically connected and integrated with the circuit board 19 and, as a matter of course, is electrically connected to the electronic circuit of the circuit board 19 as is well known.

For the IC card holder 18 provided in the main body 3 of the case 1,
In order to insert the IC card 35 from the upper surface of the case 1, an insertion port 16 having a size corresponding to the IC card 35 is provided on the upward surface 2 a of the surface member 2 of the case 1.
Around the IC card insertion opening 16 provided on the surface of the case, a protective wall 20 having an inner space 20c corresponding to the size of the insertion opening 16 is provided in a standing manner. The protective wall 20 is integrally formed of an arbitrary hard material such as a synthetic resin material or a metal material, like the surface member 2. However, what was formed with another material may be attached later.

  20b is a concave portion for IC card operation formed at the upper position of the protective wall 20, and it is known to push-in and push-out in the holder 18 with a fingertip when inserting or removing the IC card 35. It is formed so that a depth dimension sufficient to operate the mechanism is obtained. In the case where the type of the IC card 35 is different and the card is inserted and removed by other well-known means, it is only necessary to form a recess 20b that is a cut so that the IC card 35 can be picked with a fingertip. . It is preferable that a rising wall 20e for preventing dust from entering the IC card insertion slot 16 remains below the bottom surface 20d between the bottom surface 20d of the recess 20b and the top surface 2a.

  The depth of the insertion hole 17 of the IC card 35 in the IC card holder 18 is such that the upper end 36 of the IC card 35 stands up around the IC card insertion slot when the IC card 35 is inserted and the mounting is completed. The upper end surface 20a of the formed wall 20 and the bottom surface 20d of the recess 20b are set to be located at L2. Therefore, the IC card 35 in the holder 18 can be inserted and removed by a known operation with a fingertip when the IC card is inserted into or removed from the holder 18.

As shown in the figure, the protective cap 23 shown in FIG. 5 has a wall around it, is surrounded by a wall, and has a hollow 31 inside. The cross-sectional shape is formed in a reverse concave shape as shown in FIG. As the material, an elastic material is used, and it is made of a rubber-based or synthetic resin-based material (for example, an elastomer). The inner shape is elastically detachable as shown in FIGS. 3B and 4 with respect to the protective wall 20 standing around the IC card insertion slot 16 provided on the surface 2a of the case. It is designed to be used.
The plurality of ridges 32 provided on the inner surface of the protective cap 23 are provided at intervals, and can be bent here when they are put on the periphery of the protective wall 20, while increasing the degree of fitting of the protective cap 23. Helps to remove and attach it with light force.

The height L4 in the inside 31 of the protective cap 23 is such that the protective cap 23 is placed around the protective wall 20 as shown in FIG. In a state where it abuts on the surface 2a, the gap is formed so that a slight gap 38 is formed between the ceiling lower surface 24a inside the protective cap 23 and the upper end surface 20a of the protective wall 20. If the slight gap 38 is formed, even if other objects fall on the ceiling member 24 of the protective cap 23, a strong wall 25 rises around the protective cap 23 as shown in the figure. Therefore, the degree of applying a weight to the upper end 36 of the IC card 35 in the holder 18 can be reduced and damage can be prevented.
Reference numeral 27 denotes a string member that is inserted into the mounting hole 29 provided in the upper surface 2a of the case to prevent the protective cap 23 from being lost. is there. 28 is a drawing member formed thicker than the hole diameter of the attachment hole 29, and has a plurality of cuts 28a as shown in the drawing so that the outer diameter of the drawing member 28 can be reduced to the inner diameter of the hole. Reference numeral 30 denotes an operation knob that protrudes laterally as shown in the figure.

  In the structure described above, the surface member 2 is provided with a large number of electronic device elements (switches, input terminals, displays, etc.) for operating the functions of the electronic device as is well known. On the other hand, when the IC card insertion slot 16 surrounded by the protective wall 20 is provided, there is an advantage that the setting place can be set very easily because a small area is sufficient for providing the IC card insertion slot 16 at the design stage. is there.

  Further, in the above-described configuration, when the IC card is inserted into the IC card holder, even if the wide flat surface of the case is used upward, obliquely, or horizontally, dust or dirt Can be prevented from falling into the IC card holder from the IC card insertion slot, and in addition, dust on the top surface of the electronic device case and dust falling from above can be removed by attaching a protective cap. There is also an advantage that it can be completely prevented from falling into the IC card holder.

  Among the above examples, some embodiments may be understood as follows. In the above description, as an electronic device case, for example, a level checker case has a wide flat operation surface, and in the field use, the display provided on the wide flat operation surface is used. In addition, an example in which the insertion direction of the IC card is also directed in the vertical direction has been described. However, in the case of electronic equipment cases that are equipped with ultra-thin liquid crystal displays on the front side of the case and whose case depth is extremely small, such as communication devices, measuring instruments, and oscilloscopes, the IC card insertion direction is wide. Since it is the front-rear direction of the operation surface, the terms indicating the vertical direction in the present specification, for example, upward, up-down, start-up, etc. should be understood by changing to terms such as forward, front-rear direction, and protruding forward.
