Description

[Detailed explanation of the idea] The present invention relates to a computer housing structure.

Calculator-type calculators are not only used for office and home use, which are currently widely used, but also can be connected to various measurement and measurement devices and store a large amount of measurement data from those measurement and measurement devices. There are dedicated calculators for performing arithmetic processing on these data and inputting initial values to measuring instruments, and various types of calculators have been developed and used in recent years.

For example, in the field of surveying, electronic transits, light wave distance meters, and calculators for total stations are either hand-held due to restrictions on the use of the master device, or are attached to a tripod on which the master device is attached. Used by hanging. Also, when not in use, it is naturally hung on the tripod so that it does not interfere with the use of the master device.

However, when trying to process data on a desk, conventional calculators have the disadvantage that if the hook member is attached to the bottom of the calculator, the calculator is uncomfortable to sit on, making it difficult to perform calculation operations. . To solve this problem, there are methods such as attaching a hook to the upper side or making it a pull-out type, but these methods have the drawback of being complicated in structure and increasing in price.

Also, with the calculator hanging on a tripod,
When operating the calculator, the calculator was located approximately parallel to the tripod, which made it difficult to operate the keyboard, and the display was difficult to see.

Therefore, the present invention was devised to eliminate the above-mentioned drawbacks of conventional calculators, and its first purpose is to create a housing structure for the calculator in which the hook member does not get in the way when used on a desk. It is to provide. A second object of the present invention is to provide a new calculator housing structure that allows easy keyboard operation and an easy-to-see display when used on a tripod.

In order to achieve the above object, according to the present invention, a cut-off slope is formed at the bottom of the casing corresponding to the position where the display section is arranged, and the tip of the cut-off slope is connected to the contact portion of the bottom of the casing. A calculator housing structure is provided having a hook member located substantially flush with or within the same plane as the calculator. Further, in one embodiment of the present invention, the hooking surface of the hook member is made substantially parallel to the cut-off slope.

With this type of housing structure, the hook member does not get in the way when used on a desk, and when used by hanging it on a tripod,
The calculator is tilted to the tripod so that it can be mounted more horizontally, making it easier to operate the keyboard and see the display.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an external perspective view showing a first embodiment of a calculator casing according to the present invention, and FIG. 2 is a side view thereof. A keyboard section 3 is attached to the upper surface 2 of the housing 1. Further, the upper surface 2 has a display section 4
It has a part 5 on which the keyboard part 3 is attached, which part 5 is inclined with respect to the upper part on which the keyboard part 3 is provided. On the other hand, the main bottom surface 6 of the housing 1 corresponding to the keyboard section 3 is approximately parallel to the top surface 2, and the bottom section corresponding to the display section 4 is cut with an angle of inclination θ to the main bottom surface 6. It is a falling slope 7. A hook member 8 is attached to the cut-off slope 7 , and the tip end 9 is located in the same plane as the reference plane 10 including the bottom surface 6 or closer to the cut-off slope 7 . Hooking surface 11 of this hook member 8
are formed substantially parallel to the bottom surface 6.

FIG. 4 shows the calculator incorporated in the casing constructed as described above, in use, mounted on a tripod. The calculator 100 having the above-described case structure has a base 200
It is hung by a hook member 8 on a hanger fitting 204 attached to a leg 203 of a tripod 202 on which, for example, a total station 201 is attached. At this time, the main bottom surface 6 of the calculator 100 is
It closely contacts the outer surface 203a of the leg 03 and is stably held on the leg outer surface. This calculator 100 is connected to the total station via a data transmission cable 205, takes in various measurement data from the total station, performs arithmetic processing, and displays the results on the display unit 4.

FIG. 3 is a side view showing a second embodiment of the present invention, and components that are the same or equivalent to those of the first embodiment described above are given the same reference numerals and explanations will be omitted. In this embodiment, a portion 5 of the top surface 2 where the display portion 4 is provided and a portion where the keyboard portion is provided are substantially on the same plane, and a hook 8 attached to the cut slope 7 is located on the same plane. Hook surface 11
are configured to be substantially parallel to the cut-off slope 7. Furthermore, two foot parts 12 (only one is shown in FIG. 3) are attached to the main bottom surface 6 on the opposite side to the display part 4 side, and a hook member 8 is attached.
The tip 9 of the is designed to also function as a third leg.
A plane 13 including the tips of the two legs 12 and the tip 9 of the hook member 8 extends downward to a position where it does not intersect the main bottom surface 6. As a result, when the calculator is used on a desk, the feet 12 and the tip 9 of the hook member 8 contact and support the desk surface, thereby stabilizing the calculator. In this embodiment, since the hooking surface 11 of the hook member 8 is configured to be approximately parallel to the cut-off slope 7, the calculator 400 having this housing structure can be mounted on a tripod 202 as shown in FIG. When hung on the hanger fitting 211 of 210, the calculator 40
0 is stably held on the leg outer surface 211a by the boundary ridge line 14 between the bottom surface 6 and the cut-off slope 7 and the hook member 8, and is attached so as to be inclined at an angle γ with the leg. This makes it easier to operate the keyboard and also makes the display easier to see.
