1. Field of the Invention
The present invention relates to a sound control calculator and a use thereof in a pen.
2. Related Art
In daily life, many things are required to be managed by using “calculation” (for example, performing statistics on costs or counting the number of goods). If the calculation is performed by thinking, the process is quite tedious. A “calculator” is one of the most common and convenient tools for calculation. Therefore, calculators are widely used in office affairs, home financing, and shopping settlement. As shown in
Further, when using a common key-press calculator, the numeric keys of the key set (62) must be pressed by a finger (50) to input, thus errors are inevitable. As shown in
In a pen calculator disclosed in U.S. Pat. No. 6,104,603, the calculator is attached on an upper part of a pen. However, errors still occur when pressing with a finger, and thus a cap must be used to press. When being used, the calculator must be moved in the axis direction, and the cap is rotated, so as to press the keys of the calculator with the end of the cap. In addition to the inconvenience of inputting numerals in the manner of x-y axis, the keys are easily be pressed by mistake. Therefore, the design is not imperfect. ROC Publication No. 354664 discloses a calculator pen structure for handwriting input. Referring to
The patent seems creative, but it still has the following problems in practice.
1. The pen core is a non-rigid body, when an expanded end is used as a fulcrum at a site near an end of the pen core, and the handwriting is magnified by the other end due to the lever principle, the handwriting is affected by the flexibility, the elastic deformation, and the bend under pressure of the thin and long pen core at the contact pin end. Therefore, the accuracy is doubtful.
2. The penpoint of the pen core is sharp, so it is likely to shake during writing, and the received signal of the handwriting is not clear enough due to the resonance of the two springs, together with the deformation of the pen core.
3. It requires many connection pieces for transferring the handwriting track through the shift of the bar-shaped pen core, and thus the signal is likely to be disordered
4. The digital plate is likely to be damaged when the contact pin scratches thereon.
It can be seen from the patents in prior art that the pen and the calculator are generally assembled together. However, in a general view of the existing patents, no preferred assemble design is provided, and thus the patents are not desired in practical use. The present invention is directed to a indeed novel and practical calculator capable of being applied on a pen, such that the sound control calculator and the pen are assembled into a calculator device facilitate to handwriting, convenient for reading, and accurate in calculating, and more particular, to a convenient and practicable calculator or a pen using the device by assembling a sound control electronic structure.
The present invention is directed to a fluent and accurate sound control calculator pen. The sound control calculator pen mainly includes a long case with a circuit board disposed therein. The circuit board at least includes a microphone, a recording key, a voice recognition chip, and a display screen for operation. During using, a password can be executed at the microphone. The password is set by the recording key, and is executed through the operation of the voice recognition chip, and then numerals are displayed on the display screen as the operation result. Therefore, the process is rapid, has no errors as in the conventional key-press calculator. The calculator has a small volume, thus being accurate and convenient in use.
The present invention is further directed to a sound control calculator pen has a pen core disposed at an end of a case. The operation results of the sound control calculator mentioned above can be written by a pen end when filling in data, thus being convenient and rapid in use.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
The present invention will become more fully understood from the detailed description given herein below for illustration only, and thus are not limitative of the present invention, and wherein:
In order to make the examiners to understand the technical contents and efficacy of the present invention, preferable embodiments are described in detail with reference to the drawings hereinafter.
Referring to
The upper cover (11) can be designed to assume a converged shape at the front end to form an end portion (116) of the pen.
The case (10) has an accommodation space (120) in the bottom cover (12), and a plurality of pillars (121) disposed at the periphery thereof, for fixing the internal electric device and being latched with the upper cover (11) to form a long case (10). The bottom cover (12) can be designed to be a converged pen-shaped end portion (123). When the upper cover (11) and the bottom cover (12) fit together, a pen core (40) can be disposed at a position on the front end, so as to form a basic pen for writing, such that the present invention has the function of writing.

The present invention has the following advantages.
1. The present invention is a sound control design, and the phonetic password (it is a basic principle of common sound control) of the user is generally required to be pre-recorded, thus having a secret keeping (exclusive) effect; the electronic operation is more accurate than the conventional connecting lever transmission, and thus the “mathematic operation” is accurately and conveniently used in daily life.
2. The present invention is a long bar-shaped calculator design, particularly with a pen core, such that the pen-shaped calculator has the function of hand writing of a pen and is more time-saving and portable than a common long block-shaped calculator. When being used, the present invention can get the calculation result by performing sound control vocalization in an available space under any circumstance, and write the calculation results, and thus being more convenient than conventional calculators. Moreover, the present invention has no error of the key-press calculators, and thus being more accurate in use.
The present invention is a special and novel design, and has a simple structure and creativeness. If other function keys are simply added, the present invention will be more advantageous. The present invention is in the form of a sound control calculator, has a bar-shaped body, and has a structure of a pen, thus the integral combination has practicability, creativeness, and industrial application value. Therefore, the features of the present invention utilized merely with simple additions still fall within the scope of the content of the present invention. It is especially pointed out that, the specification and figures of the present invention are exemplification of preferred embodiments of the present invention, but not intended to limit the scope of the present invention. Equivalent structure variations of the specification and figure content of the present invention fall within the scope of the present invention.
The present invention has the advantages of convenient in use, accurate in read, and portable and has industrial application value without being published in similar structural application, and thus it meets the essential requirements for invention patent, so it is filed for patent, and we will be appreciated if it is granted with invention patent by your examiner.
