Definitions
- the present invention relates to the field of calculators for the conversion of currencies.
- It relates more particularly to a device for determining and / or recording the price of an article of a first currency, for example a national currency, from the price displayed in another currency, for example in EURO, and vice versa .
- German patent DE29613106 described for example describes a pocket calculator comprising a keyboard for entering the amount to be converted and keys specific to the conversion operation.
- European patent EP104709 describes a portable device which can be used with one hand. This device comprises a plurality of functional keys arranged on the side of the housing.
- the German patent DE29613106 describes a calculation aid for carrying out calculations with simplified manual entry of the operands by means of one or more control elements.
- the operands are introduced by means of a numerical keyboard.
- One-handed use is almost impossible or very complicated if there is no suitable support.
- the object of the invention is to provide a new calculation aid designed for use with one hand, this aid being handled and maintained by one and the same hand, the other hand remaining free for other operations.
- the operands are entered by position.
- the basic symbol required for the entry position is selected by repeatedly actuating the same control element from the basic symbol set.
- the calculation unit allows all operations to be carried out. For example, several amounts can be entered one after the other by means of three control elements and displayed in the form of a sum.
- the invention relates in its most general sense to a device for converting a price expressed in a first currency (B1) into a price expressed in a second currency (B2) characterized in that it comprises: a first button two positions for
- the device does not include a numeric keyboard.
- the speed of variation of the amount displayed is a function of the pressure exerted on the first button.
- the device according to the invention comprises means for trigger the conversion of the displayed amount after a predetermined delay in activating the first button.
- the box includes a box suitable for use by one hand with a liquid crystal screen which is used to display the data (or monetary values), the buttons being arranged on the side to allow activation by the fingers. of the user.
- the single figure represents a front view of an embodiment of the device according to the invention.
- the present invention relates to a device making it possible to convert a given currency into another (Bl) and to record (B2) or deduct (B3) the price of the desired item so that the user can permanently know the sum of his expenses.
- This device is characterized in that it comprises a button (Bl) located on the side of the housing.
- the button (Bl) allows you to search for the registered currency.
- the user can by a thumb pressure forwards scroll the values progressively, up to 9999.99 according to the intensity and the duration of the pressure, in the same way the user can by a pressure of the thumb towards l 'backward scroll down, to 0, by the same process the value it wants to obtain.
- the user releases the (Bl) on the selected value.
- the device converts the value chosen by the user into another monetary value.
- the number chosen by the user is representative of a currency which is automatically converted by the device program to another currency.
- the second button (B2) is characterized by the fact that it makes it possible to record the values chosen by the user which are automatically added by the device. The sum of these numbers is permanently displayed on the screen except for the use of the button (Bl).
- the third button (B3) is characterized by the fact that it makes it possible to erase the value chosen by the user (Bl) which is deducted from the sum recorded by (B2).
- the device is characterized in that it comprises a housing suitable for use by one hand with a liquid crystal screen which is used for displaying the data (or monetary values).
- the plastic covering the display has a magnifying effect by using the magnifying effect.
- the device is characterized by the fact that it allows advertisements to be placed on the free surfaces of the device.
- the device has four buttons:
- - A push button (B2) registration) allowing the entry of a price and the addition of the latter with the existing cumulation.
- -A button (B3) (subtraction) allowing the entry of a price and the subtraction of the latter with the existing cumulation.
- the device consists of an up / down counter whose outputs are connected to a binary / decimal decoder. At the output of the decoder the values are converted (in Franc, Euro; etc %) and sent simultaneously to the liquid crystal display and a memory box. Another memory box makes it possible to memorize the cumulation and to display it at any time on the display.
- the letters E, U, R, 0 as a non-limiting example scroll and then the word EURO is displayed for a determined time on the display. Following this time, the same process occurs for the word Franc.
- the direction of the conversion is chosen (for example: EURO to FRANC).
- the button (B2) the numbers scroll on the display until you get an exact price (you can easily make adjustments using the two positions of the button (Bl) + / -).
- the display allows you to arrive, using the + and - button, at the price to be entered; and the memory box allows in the case where the article is taken to carry out the operations of seizure and accumulation as follows: by pressing the button (B2) (save) the value displayed on the display is entered in a memory box.
- This memory box is connected to the input E2 of an accumulator, another memory box (cumulative box) is connected to the input El of the accumulator, the output S of the latter is connected to the cumulative memory box.
- the value entered (price of the item) will be added to the value of the existing total, this new total will be loaded in the cumulative memory box and displayed at the same time on the display.
- buttons (Bl) If you wish to withdraw a price (change or refusal of an item already registered) using the button (Bl), you display the price to be removed and then press the button (B3) (delete) whose role is exactly identical with the button (B2) except that in this case the accumulator performs a subtraction operation.
