There is a stand member that is configured to be hooked by stoppers d and e provided on b and that allows the keyboard housing f to be set upright (see actual climbing 30085865).

[0003]

Input operation panels with input keys include keyboards of personal computers, calculators, electronic music keyboards, game machines, and the like, and in the future, a wide variety of liquid crystal display devices with input keys will be provided. I / O terminals were developed,
It is expected to be used in various places. In addition, as a personal computer or a communication terminal, the rate of use at home tends to increase further. These input operation panels are normally used with the operation surface facing up, but the operation surface of the input operation panel cannot be made too small. Has become. Further, depending on the place of installation, the appearance may give an uncomfortable feeling. Therefore, in order to make more effective use of the limited work space, it is necessary to clean up the work space at least when not in use so that it does not interfere with other work, or a separate display such as a computer keyboard. When using it together with the display, when checking while collating the display with the material, or when temporarily operating with an input device other than the keyboard, there is also a request to clean up the keyboard and use the space. is there. As a functional requirement of the stand tool for the input operation panel that satisfies such requirements,
With simple operations, you can repeat operations such as standing and returning in a short time, and there is a structure that holds the standing state securely. However, although the conventional technique is excellent in general operability, since the keyboard housing is erected only by the stand shaft, the rotation moment of the keyboard housing is applied to the rotation shaft portion of the stand shaft. become. Therefore, with this technology, it is necessary to separately provide a stopper on the holder to stop the rotation moment, and when the keyboard housing is heavy, a considerable force acts on the stopper, which hinders downsizing and appearance design. There was a problem such as doing.

The present invention has been made in view of the above problems of the prior art, and its object is to mount the same on the housing of the input operation panel to be used while lying down. An object of the present invention is to provide a stand tool that can easily and repeatedly perform an operation of standing up the housing that has been laid down when the input operation panel is not used.

[0005]

In order to achieve the above object, in a stand tool for an input operation panel according to the present invention, one end of a stand shaft is rotatably supported on a support base, and the stand is rotatably supported. At the other end of the shaft, there is provided a rotating shaft portion for rotatably supporting on the operation panel housing, and the front side portion of the operation panel housing which supports the stand shaft and stands upright on the support base. Rear side,
It is configured to be locked by a locking portion provided on the support base.

Further, a rotary shaft portion for rotatably supporting on the operation panel housing is provided at one end of the stand shaft, and a support base is provided so as to rotate near the front side portion with respect to the operation panel housing. It is possible to mount the operation panel housing on the operation panel housing and lock the other end of the stand shaft by the locking portion provided on the support base so that the operation panel housing can be set upright.

[0008]

The input operation panel equipped with a stand tool in which the operation panel housing and the support base are rotatably supported on the stand shaft is connected to the support base via the stand shaft. The body rotates about the rotation shaft portion of the stand shaft. Further, in a state in which the operation panel housing is laid on the table, that is, in a fixed position of the operation panel housing, the support rests the back surface of the operation panel housing. When the rear side surface of the operation panel housing is raised in this state, the support base pivotally supported by the stand shaft slides on the table toward the front side surface side. Therefore, when the operation panel housing is lifted a little and the front side surface is floated, the tip of the support base on the side of the locking portion enters between the operation panel housing and the table surface. When the operation panel housing is lowered at this point, the operation panel housing is in a state in which the standing front side surface is placed on the support base. On the other hand, if the front side surface side of the operation panel housing in the fixed position is raised and inverted as it is, the operation panel housing will be in an inverted state while sliding the rear side surface on the support base. In any of these cases, a triangle formed by the operation panel housing, the support base and the stand shaft is formed. In this state, when the front side surface or the rear side surface of the operation panel housing placed on the support table is locked by the locking portion provided on the support table, a closed force triangle is formed, and the operation panel housing is formed. Holds a triangle consisting of a support and a stand shaft. This means that the operation panel housing is supported and held by the stand shaft on the support base. On the other hand, the occupying area when the operation panel housing is erected on the table is the projected area of the operation panel housing and the support stand on the table, so the operation panel housing was laid on the table. It shrinks obviously compared to the case.

Further, when the stand shaft and the support base are individually attached to the operation panel housing so as to be rotatable, the rear side of the operation panel housing in the fixed position is raised. Then, the stand shaft pivotally supported by the operation panel housing rotates by its own weight, its free end moves toward the locking portion provided on the support base, and is locked by the locking portion. It becomes possible to stand the operation panel housing on the support base.

The rotating shaft portion of the stand shaft can be rotatably supported on a pair of holders fixed to and integrated with the operation panel housing, and the holders can be fixed on the operation panel housing. Even with the structure, the operation of the support base and the stand shaft described above does not change at all.

Since the present invention is constructed as described above, it has the following effects.

In the stand tool for the input operation panel described in claim 1, when the operation panel housing which is laid down and stands, is placed on the support stand, the operation panel housing and a stand which is a component of the stand tool. The shaft and support form a closed force triangle. Since only the force along each side acts on its constituent sides, no rotation moment acts on the rotation shaft portion of the stand tool. Comparing the case where the stand shaft and the support base according to the present invention are used with the case where only the stand shaft according to the conventional technique is used, in the former case, a simple locking or slip prevention utilizing the weight of the operation panel housing is performed. Since it can be held in a manner, a simpler locking structure can support a larger load. Further, most or all of the stand shaft and the support base are always hidden behind the operation panel housing, so that they are visually inconspicuous and do not physically obstruct. In addition, the operation panel housing can be placed upright and returned without touching the stand at all, making it extremely easy to operate, quick and reliable, and requiring less force. Repeatedly does not cause any trouble. Further, since the operation panel housing erected on the support base is supported by the entire surface of the support base, it is hard to fall down and is stable. In this way, since the vertically raised operation panel housing is securely held, when used in an input operation panel with keys, key input operation can be performed even in the upright state. Also,
By raising the input operation panel, the area occupied by the operation panel housing on the table can be reduced to 1/3 or less. On the other hand, since it is possible to have a structure in which both operations of raising and raising the operation panel housing on the support base can be performed, the operation surface can be orientated to the front depending on the situation, The two operations such as facing the back can be used properly, and the effect of reducing the area occupied by the two does not change.
If you set the back face up to the front, the operation surface will be hidden behind the operation panel housing, so you can prevent dust from adhering to the operation surface and prevent accidental input by touching keys. Also becomes. Furthermore, if you print graphics, letters, pictures, photos, etc. designed for decoration on the back of the operation panel housing or attach them as stickers, etc., it will look like a decoration when placed upside down with the back facing. Since it will be an appearance, for example,
For general household use, you can make it look comfortable by choosing a decorative design that fits the storage location. Also,
Other uses on the back include displaying advertisements and operating procedures, pasting calendars and schedules, and combining an input operation panel with a digital clock. As described above, the stand component according to the present invention is characterized by having a mechanism that enables dynamic and repetitive operations.
It has a simple structure, lightweight, low price and excellent appearance design.

In the stand tool for the input operation panel described in claim 2, the mechanism for holding the operation panel housing is the same as that according to claim 1, so that the effect of reducing the occupied area is the same and the operability is almost the same. You can expect something. In addition, since the stand shaft and the support base are independently mounted on the operation panel housing, the stand shaft and the support base are easily stored in the back surface of the operation panel housing or the like. Therefore, it is convenient to use it as a portable input operation panel that is often carried around.

The stand member for the input operation panel described in claim 3 can be easily mounted on anyone by simply fixing the holder without mechanically processing the operation panel housing such as a conventional keyboard. A stand tool can be attached. Further, this holder has a simple structure and can be manufactured at low cost. Furthermore,
Since it is inconspicuous and has an excellent appearance, it hardly harms the appearance design of the input operation panel.
