By the way, recently, an electronic device having a leg portion extending rearward from a lower end portion of a main body portion having an operation panel on the front side is known. It is assumed that such an electronic device is used, for example, for ordering at a restaurant or the like. In an electronic device used for such an application, for example, an operation panel is operated while being installed on a tabletop.

However, in such electronic devices, heavy objects such as displays and batteries are often mounted on the main body, and in this case, the center of gravity of the entire electronic device is located on the main body. Therefore, when the operation panel is operated, the electronic device may be tilted. In addition, it may be difficult to balance when installing an electronic device on a table or the like. In order to solve such a problem, for example, it is conceivable to attach a weight to the leg to ensure stability, but this is not preferable because it increases the weight of the entire electronic device.

Further, it is considered that the proposals of Patent Documents 1 to 3 can be applied to such an electronic device, but there is room for improvement in consideration of the usage mode thereof.

On one aspect, the electronic device disclosed herein is an object of improving the stability of an electronic device having a main body having an operation panel on the front side.

The electronic device 1 in this embodiment is a communication terminal device. The electronic device 1 can be used, for example, for ordering a menu at a restaurant, selecting music in a karaoke box, or the like.

The electronic device 1 includes a main body portion 10 and a leg portion 30. The main body 10 includes a main body housing formed by combining a resin front case 11 and a rear case 12, respectively. The main body 10 includes a liquid crystal panel 14 supported by a liquid crystal panel support 13. Further, the main body 10 includes a touch panel 15 installed so as to be stacked on the liquid crystal panel 14. The touch panel 15 is an example of an operation panel. The touch panel 15 is arranged on the front side of the main body 10. The operation panel may be, for example, a panel provided with a push-in type button.

The main body 10 includes a substrate 16 inside. Further, the main body 10 includes an antenna 17. As a result, the electronic device 1 realizes a function as a communication terminal device. The main body 10 is equipped with a battery 18 covered with a battery cover 19.

A main body protection member 20 is attached to the peripheral edge of the main body 10. The main body protection member 20 functions as a shock absorbing member (damper) of the electronic device 1, and can be formed by using a conventionally known material. The main body protection member 20 in this embodiment is made of urethane elastomer. Referring to FIGS. 4A to 4F, the main body protection member 20 includes an upper edge 201, a right edge 202, and a left edge 203, and is a substantially rectangular lower edge of the main body 10. It is designed to be attached to three edges except.

The leg portion 30 extends rearward from the lower end portion of the main body portion 10. The leg portion 30 includes an upper cover 31 and a lower cover 32 made of resin, respectively. The front end side of the upper cover 31 is connected to the main body 10 by a screw 33. As a result, the leg portion 30 is fixed to the lower end portion of the main body portion 10 so as to extend rearward. The lower cover 32 is fixed to the upper cover 31 by screws 34. The screw 34 is inserted upward from the bottom surface side of the lower cover 32.

A front grounding portion 35 and a rear grounding portion 36 are provided on the bottom surface of the lower cover 32, that is, the bottom surface 30a of the leg portion 30. The front grounding portion 35 and the rear grounding portion 36 are provided at two locations each. Specifically, the front grounding portion 35 is provided at two locations in parallel in the left-right direction, and the rear grounding portion 36 is also provided at two locations in parallel in the left-right direction. When the electronic device 1 is installed on the table top surface 50 (see FIG. 8), the electronic device 1 is installed in a state where a total of four points, the front grounding portion 35 and the rear grounding portion 36, are installed.

Referring to FIGS. 5A to 5C, the front ground contact portion 35 is circular in a plan view and includes a spherical portion 35a at the bottom. When the electronic device 1 is installed on the table surface 50, the spherical portion 35a comes into contact with the table surface 50. The front ground contact portion 35 can be formed of a conventionally known material having elasticity. In the present embodiment, the front ground contact portion 35 is formed of silicon rubber. The front grounding portion 35 may have a cylindrical shape or the like, for example, but by providing the spherical portion 35a, it is possible to suppress the catching on the table surface 50.

The rear grounding portion 36 is also formed of silicon rubber like the front grounding portion 35, and has substantially the same shape as the front grounding portion 35. Therefore, the rear grounding portion 36 also includes the spherical portion 36a. As a result, it is possible to suppress the hooking on the table surface 50. However, the height of the rear ground contact portion 36 is formed to be slightly lower than the height of the front ground contact portion 35. In the present embodiment, the rear ground contact portion 36 is formed so as to be about 0.5 mm lower than the front ground contact portion 35. This will be described in detail later.

The front grounding portion 35 and the rear grounding portion 36 are attached to the bottom surface 30a of the leg portion 30 so as to cover the head of the screw 34 for fixing the lower cover 32 to the upper cover 31. In the present embodiment, an adhesive is used for mounting the front grounding portion 35 and the rear grounding portion 36, but double-sided tape or the like can also be used.

A leg protection member 37 is attached to the peripheral edge of the leg 30. The leg protection member 37 functions as a shock absorbing member (damper) of the electronic device 1, and can be formed by using a conventionally known material. The leg protection member 37 in this embodiment is made of urethane elastomer. Referring to FIGS. 6 (A) to 6 (F), the leg protection member 37 includes a trailing edge portion 371, a right edge portion 372, and a left edge portion 373, and the front end edge of the substantially rectangular leg portion 30. It is designed to be attached to three edges except.

The leg protection member 37 is provided with a front protrusion 37a and a rear protrusion 37b. Specifically, the right side edge portion 372 and the left side edge portion 373 are provided with the front protrusion portion 37a, respectively, and the trailing edge portion 371 is provided with the rear side protrusion portion 37b.

Here, referring to FIG. 7, the front projection portion 37a is provided on the bottom surface 30a of the leg portion 30 in front of the front ground contact portion 35. Further, the rear projection portion 37b is provided on the bottom surface of the leg portion 30 behind the rear ground contact portion 36. In the present embodiment, such a positional relationship is realized by attaching the leg protection member 37 provided with the front protrusion 37a and the rear protrusion 37b to the peripheral edge of the leg. The front protrusion 37a can suppress the electronic device 1 from tipping forward. In addition, the rear protrusion 37b can suppress the electronic device 1 from tipping over to the publication. The front protrusion 37a and the rear protrusion 37b may be formed on the lower cover 32.

The above is a schematic configuration of the main body 10 and the legs 30 of the electronic device 1.

Here, the relationship between the dimensions of each part and the like will be described in more detail with reference to FIGS. 8 to 10. Referring to FIG. 8, the rear ground contact portion 36 is adhered to the lower surface of the lower cover 32, that is, the recess 30a1 provided on the bottom surface 30a of the leg portion 30. The front ground contact portion 35 (not shown) is also adhered to the bottom surface 30a of the leg portion 30 in the same manner. Referring to FIG. 9, the height h1 of the front grounding portion 35 with respect to the bottom surface 30a is set higher than the height h2 of the rear grounding portion 36 with respect to the bottom surface 30a. As a result, as shown in FIG. 10, the electronic device 1 installed on the table surface 50 is in a slightly backward tilted posture, and a stable state can be maintained. Specifically, in the present embodiment, the rear ground contact portion 36 is formed so as to be about 0.5 mm lower than the front ground contact portion 35.

Since the electronic device 1 is provided with a heavy object such as a liquid crystal panel 14 or a battery 18 in the main body 10, the center of gravity of the electronic device 1 is located in the main body 10. That is, the position of the center of gravity of the electronic device 1 is located closer to the front side of the electronic device 1. Therefore, the electronic device 1 can be stabilized by tilting the posture of the electronic device 1 backward due to the height relationship between the front grounding portion 35 and the rear grounding portion 36 installed on the table top surface 50.

In the present embodiment, the height of the front grounding portion 35 itself is formed to be about 0.5 mm higher than the height of the rear grounding portion 36 itself, so that the posture of the electronic device 1 is tilted backward. Depending on the shape of the bottom surface 30a of the leg portion 30, the posture may be tilted backward. For example, a pedestal portion may be provided on the mounting portion of the front ground contact portion 35 on the bottom surface 30a of the leg portion 30, and a backward leaning posture may be created depending on the height thereof. In short, any means can be used as long as the posture of the electronic device 1 can be tilted backward while the front grounding portion 35 and the rear grounding portion 36 are grounded to the table surface 50.

When the electronic device 1 is tilted backward on the table surface 50, the touch panel 15 faces slightly upward, which facilitates its operation. Further, even if a force pushed backward is applied to the main body portion 10 when the touch panel 15 is operated, the rear grounding portion 36 can receive the force and maintain a stable state of the electronic device 1. be able to.

Next, the relationship between the heights of the front ground contact portion 35 and the front protrusion portion 37a will be described. When the electronic device 1 is installed on the table surface 50, the front grounding portion 35 is grounded to the table top 50, but the front protrusion 37a is not grounded. In order to realize such a state, the height of the front projection portion 37a is set lower than the height of the front ground contact portion 35 when the bottom surface 30a of the leg portion 30 is used as a reference. In the present embodiment, the height of the front protrusion 37a is set to about 1 mm. The front grounding portion 35 sinks by about 0.1 mm under the weight of the electronic device 1 when the electronic device 1 is installed on the table surface 50, but the front protruding portion 37a having a height of about 1 mm is the front grounding portion. Even if 35 touches the table surface 50, it does not come into contact with the table surface 50.

Next, the relationship between the heights of the rear ground contact portion 36 and the rear projection portion 37b will be described. When the electronic device 1 is installed on the table surface 50, the rear grounding portion 36 is grounded to the table surface 50, but the rear protrusion 37b is not grounded. In order to realize such a state, the height of the rear projection portion 37b is set lower than the height of the rear ground contact portion 36 when the bottom surface 30a of the leg portion 30 is used as a reference. In the present embodiment, when the electronic device 1 is installed on the table surface 50, the difference between the height of the rear ground contact portion 36 and the height of the rear protrusion 37b is set to be about 0.3 mm. .. When the electronic device 1 is installed on the table surface 50, the rear grounding portion 36 sinks by about 0.1 mm under the weight of the electronic device 1, but in this state, the difference in height between the two is 0. It is set to be about 3 mm.

Next, the hardness of the front ground contact portion 35 and the hardness of the rear ground contact portion 36 will be described. The hardness of the front ground contact portion 35 and the hardness of the rear ground contact portion 36 are lower than the hardness of the front protrusion portion 37a and the hardness of the rear protrusion portion 37b. In other words, the front ground contact portion 35 and the rear ground contact portion 36 are softer than the front protrusion portion 37a and the rear protrusion portion 37b. The front grounding portion 35 and the rear grounding portion 36 are grounded to the table top surface 50 when the electronic device 1 is installed on the table top surface 50. The front grounding portion 35 and the rear grounding portion 36 can be deformed to increase the contact area with the table surface 50 by providing an appropriate hardness and an appropriate flexibility. As a result, it can be installed on the table surface 50 in a stable state. Further, as shown in FIG. 10, even if a force F is applied to the main body 10 during the operation of the touch panel 15, the front ground contact portion 35 and the rear ground contact portion 36 are appropriately deformed to prevent the leg portion 30 from slipping. can do.

On the other hand, the front protrusion 37a and the rear protrusion 37b are required to have a certain degree of hardness. The front protrusion 37a and the rear protrusion 37b function as a stopper for preventing the electronic device 1 from falling when the electronic device 1 is about to fall. Therefore, the front projection portion 37a and the rear projection portion 37b have an altitude higher than the hardness of the front ground contact portion 35 and the hardness of the rear ground contact portion 36, and are less likely to be deformed. In particular, the front protrusion 37a and the rear protrusion 37b of the present embodiment are formed on the leg protection member 37. Since the leg protection member 37 exerts a shock absorbing effect when the electronic device 1 is dropped or the like, a desired hardness is secured. The front protrusion 37a and the rear protrusion 37b can be formed on the lower cover 32, but even in this case, the hardness of the front ground contact portion 35 and the hardness of the rear ground contact portion 36 are the front side. The relationship between the hardness of the protrusion and the hardness of the posterior protrusion is satisfied.

As described above, according to the electronic device 1 of the present embodiment, the electronic device 1 is installed on the table surface 50 in a stable state, and the stability can be maintained even when the touch panel 15 is operated. Further, since the electronic device 1 of the present embodiment is provided with the front grounding portion 35, the rear grounding portion 36, the front protruding portion 37a and the rear protruding portion 37b to ensure its stability, the leg portion 30 is provided with the leg portion 30. Since it is not necessary to attach a weight, there is no weight increase for the purpose of ensuring stability.

(Other embodiments)
In the above-described embodiment, the front grounding portion 35 and the rear grounding portion 36 are provided at two locations each, but the number of these is not limited thereto. For example, as shown in FIG. 11A, the front grounding portion 35 may be provided at one place and the rear grounding portion 36 may be provided at two places. Further, as shown in FIG. 11B, the front grounding portion 35 may be provided at two locations and the rear grounding portion 36 may be provided at one location. This is because the electronic device 1 can be stabilized by grounding at least three places on the table surface 50.

Further, as shown in FIG. 12, instead of the rear protrusion 37b, a band-shaped rear protrusion 137b extending in the left-right direction may be adopted. That is, the shape of the rear protrusion can be changed in various ways. The same applies to the front protrusion.

Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the specific embodiments, and various modifications and variations are made within the scope of the gist of the present invention described in the claims. It can be changed.
