Description

[Detailed explanation of the idea] [Purpose of invention] (Industrial application field) The present invention relates to a small desktop calculator.

(Prior Art) The operation keys and display of a conventional desktop electronic calculator can only be viewed in one direction from the operator's side.

However, in commercial transactions, it is very inconvenient that the customer cannot see the operation keys. This is because in Japan, it has been a long-established custom in business transactions for salespeople and customers to take out Soroban and use the balls to negotiate prices, etc., and desk calculators are used. This is also because this is not possible when using

Furthermore, when working in an office with desks arranged side by side, the person on the other side may want to do simple calculations while holding a calculator on the desk with their arms outstretched.

(Problems to be Solved by the Present Invention) In such a case, it would be convenient if the desk calculator could be recognized not only by the user but also by the customer in person, and if the keys could be operated, and the present invention aims to solve this problem. This was done with the aim of achieving this goal.

[Structure of the invention] Hereinafter, the structure of the invention will be explained based on the drawings of the embodiment. In Fig. 1 showing a perspective view of the invention computer, 1 is the main body of the computer, and the figure shows a built-in pocket type computer. Although shown above, all other small desk-top computers can be targeted.

Reference numeral 2 denotes an operation key attached to the surface of the main body 1, and a marking layer 2b of numbers, symbols, etc., double-displayed in opposite directions is formed on the base 2a.

For example, as shown in FIG. 2, this marking layer 2b may have a substantially triangular cross section and have numbers, symbols, etc. displayed in opposite directions on both slopes thereof.
This is suitable for a case where the base 2a is relatively small and pocket-shaped. Alternatively, as shown in FIG. 3, the cross section may be approximately trapezoidal, the upper side may be used as a finger pressing part, and numbers, symbols, etc. may be displayed on both slopes in opposite directions. Suitable for general type items with ample space. Furthermore, as a special type, as shown in Figure 4, grooves that can be seen from only one direction can be cut in a transparent material such as glass, and numbers and symbols can be displayed on the bottom in opposite directions. It is excellent in that the operation keys can be kept flat.

Reference numerals 3 and 3 denote two displays for displaying the calculation results of the operation keys, which are arranged in opposite directions so that one can be easily seen by the operator and the other by the person facing the person facing the person. Although the drawings show a mode in which they are provided separately at the left and right ends of the main body 1, they may be integrated.

[Effect of the invention] Now, if a sales person uses a desktop calculator to enter into a business negotiation while serving a customer, when the operation key 2 is pressed, the face-to-face meeting will occur via the marking layer 2a of numbers, symbols, etc. displayed in the opposite direction. This can also be clearly seen by customers, and the results can be instantly and accurately read on the display 3 facing the customer.

Conversely, if the customer wants to display discounts, etc., he or she can leave the computer body 1 as is and press the operation key 2, and the sales person can then accurately confirm the operation and result. can.

Therefore, commercial transactions can be carried out smoothly by simultaneous operations from both parties, the conventional negotiation using Soroban can be reproduced, and calculations are simpler, clearer, and more versatile than Soroban. Are better.

Furthermore, when working in an office with desks arranged side by side, it goes without saying that the person on the other side can do simple calculations by simply holding a calculator on the desk and extending their arm.

As described above, the present invention is extremely useful in facilitating transactions for businessmen, stores, etc. who have been feeling inconvenienced by the functions of desktop calculators in commercial transactions.
