Description

[Detailed explanation of the idea] The present invention relates to the case of a small electronic calculator.

In recent years, there has been a trend toward smaller and thinner electronic calculators, and more and more users are storing these small electronic calculators in, for example, notebook-shaped cases and carrying them with them at all times.

On the other hand, in addition to the calculation functions such as the four arithmetic operations, the small electronic calculators mentioned above have a timekeeping function and an alarm function, and are capable of displaying the current time and sounding an alarm at a set time. has been commercialized.

However, when carrying a small electronic calculator equipped with such a timekeeping function and beeping function in the notebook-type case mentioned above, if the case is pressed, the timekeeping function and beeping function of the calculator itself may be affected. Inconveniences such as the current time display changing when a related key button is pressed or an alarm sounding at a time other than when necessary are likely to occur.

This invention was made in view of the above circumstances, and when a small electronic calculator with timekeeping function and sound alarm function is stored in a case, key buttons related to the timekeeping function and sound alarm function of the calculator body can be pressed. The purpose of the present invention is to provide a case for a small electronic calculator in which the computer is not pressed.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 3.

In the figure, 1 is a small electronic calculator, and on its upper surface there is a display section 2 that displays calculation results, current time, etc., a mode switch 3, and a group of key buttons 4 related to calculation functions, including a numeric keypad and function keys. , a group of key buttons 5 related to a timekeeping function and a sound alarm function are provided.

The mode switch 3 has a first mode for setting the time to sound the alarm sound, a second mode for setting the time when the alarm sound is to be sounded, a second mode in which the alarm sound can be sounded when the alarm button described below is operated in addition to the set time, and a calculation mode. This is for selecting and specifying the third mode when performing the process.

The key button group 5 includes a start/stop button 5a for instructing the start and end of timekeeping when used as a stopwatch, alarm buttons 5b and 5c for setting the time to sound an alarm, and displaying the current time. It is composed of a time button 5d for displaying on the display section 2 and a date button 5e for displaying the date on the display section 2.

6 in the figure is a case made of vinyl chloride, etc., and the mounting member 6
a, and a lid member 6b.

The above-mentioned small electronic calculator 1 is attached to the mounting band 7a on the mounting member 6a.
, 7b, both ends of which are supported and fixed.

In the lid member 6b, a sheet 1-8 made of hard vinyl chloride or the like is fixed to substantially the entire surface of the surface facing the small electronic calculator 1 when the case 6 is folded, and a sheet 1-8 made of hard vinyl chloride or the like is fixed to the cover member 6b. Display section 2 of formula calculator 1
A through hole 9 is formed in the cover member 6b and the sheet 8 at a position facing the .

Furthermore, ribs 10a and 10b are formed protruding from the sheet 8 at positions facing the key button group 5 when the case 6 is folded, surrounding the periphery of the key button group 5.

The ribs 10a and 10b are set at a predetermined height so that the surface of the sheet 8 and the egg surface do not come into contact when the case 6 is folded, and the ribs 10a and 10b are set at a predetermined height such that the surface of the sheet 8 and the egg surface do not come into contact with each other when the case 6 is folded.
The upper side of the figure, the left side of the start/stop button 5a,
These are formed on the periphery of the key button group 5 at positions other than those facing the lower part of the date button 5e in the drawing.

As shown in FIG. 1, the small electronic calculator 1 is supported and fixed on the mounting member 6a of the case 6 having the above-mentioned structure.The central part of the case 6 shown in FIG. .

In this stored state, the display on the display section 2 is visible from the outside through the through hole 9.

That is, by operating the time button 5d to display the current time on the display section 2, the current time can be visually recognized at all times even when stored.

At this time of storage, even if the cover member 6b located opposite the key button yg*5 is pressed, the ribs 10a and 10b prevent the sheet 8 from coming into contact with the surface of the egg, and the current time display may change. The alarm will not sound unless necessary.

Further, when the case 6 is in the stored state, the lid member 6b may move in the arrow directions A-D shown in FIG.
The vertical movement shown in B is large.

Moreover, due to the flexibility of the mounting member 6a and the lid member 6b, a gap is created between them, and this gap increases as the distance from the bent portion increases.

However, since the ribs 10a and 10b are not formed on the entire periphery of the key button group 5 but are formed near the bent portion, the ribs 10a and 10b are reliably prevented from riding on the key button group 5. The current time display will not change and the alarm will not sound unless necessary.

Note that the shape of the ribs 10a and 10b in the above embodiment is not limited to the shape shown in the drawings, but is essentially set at a height that does not allow the surface of the sheet 8 and the surface of the egg to come into contact with each other during storage, and furthermore, the lid member 6b is moved horizontally. It suffices if the key button group 5 is positioned opposite to the periphery of the key button group 5 other than the side of the related button so that when the button is moved, the display will not change and the sound will not be sounded unless necessary.

As detailed above, according to the present invention, when a small electronic calculator is housed in a case, ribs are provided on the inner surface of the lid member of the case, located opposite to the periphery of the key buttons related to functions other than the calculation function. In addition, ribs are formed in areas other than the areas where the lid member moves significantly horizontally, so even if the case is compressed or the case lid moves horizontally, the display will change or unnecessary functions will not function. It never works.
