Abstract

The utility model is an improvement on the fixing device of a pocket-size or palmtop computer handwriting pen. A magnet is arranged on the side part or/and end part (that is the top end or the bottom end) of the guide groove in which the handwriting pen is placed, and another magnet is arranged on the central part or corresponding end part, moreover, the magnetisms of the two opposite surfaces are reverse. The best shape of the magnet is a cylinder. The handwriting pen of the utility model is fixed by utilizing magnet suction principle. Because the base of the fixing force is the suction of the magnets, the performance is stable, and the mechanical wear problem does not exist, thus the life can be almost infinitely long. No matter in the using beginning or after a long time using, the force which is required to draw the pen out is relatively identical, thus the hand feel can be kept identical. Moreover the scheme is simple and easy to realize, the cost is low, so the utility model is very suitable for being adopted by extensive handwriting input devices.

Description

A kind of pocket or palm PC

Technical field

The utility model relates to a kind of pocket or palm PC, relates in particular to a kind of improvement of the writing pencil stationary installation to pocket or palm PC.

Background technology

Along with the develop rapidly of society, be used for equipment such as the PDA of personal information processing and mobile phone and begin to be used widely.And More and more factories has selected this conveniently mode of handwriting input to be used as the means of man-machine interaction.The equipment of all handwriting inputs now all has been equipped with a writing pencil, and this pen is in the guide groove of the equipment of being inserted in.All there is very big defective in the fixed solution of the used writing pencil of handwriting input device on the market at present.Up to 6188 of Motorola, the fixed solution that they adopt all is to rely on pen to finish with the friction of slot as BESTA, e-commerce, instant translator.The fatal shortcoming of this scheme is: at the beginning because friction is strong, pen is fixed relatively firmly; But As time goes on, dial to wipe the increase of number of times, begin to become lax between pen and the groove, thereby cause that pen is very easy to come off out.Tighter with what design between pen and the groove, can delay the time that this problem occurs, but can not address this problem at all, and also tension can cause just having begun the time, bad problem of getting pen.

Other has a kind of PDA to adopt slightly better scheme, has promptly designed a groove on pen, has designed a Spring lock catch then on equipment, is similar to from starting writing.But topic is sent one's regards in this design too, promptly the life-span of Spring lock catch generally not long yet, will be malfunctioning after a period of time, pen or be stuck and be difficult to take out, or button incessantly.This and those from start writing or the spring ball pen with malfunctioning after having grown the time be the same.And this method complex structure, cost is higher.

From above various schemes as can be seen, no matter be to adopt friction, or Spring lock catch, these exist the scheme of mechanical wear all to have a fatal problem: actual Acceptable life is too short.And PDA is as a kind of personal portable commonly used, as the electronics substitute of paper pen, has determined it to be used continually by the user, so a kind of scheme of desirable fixedly writing pencil will be arranged.

Summary of the invention

The purpose of this utility model is: solve the above-mentioned defective of prior art, existing writing pencil stationary installation pocket or palm PC is improved.

The technical solution of the utility model is: sidepiece or end (being top or bottom) at the guide groove of placing writing pencil are provided with a magnet, and in the relevant position, end of writing pencil another magnet are set, and two relative one side magnetic are opposite.The optimum shape of magnet is a column.

The utility model utilizes fixedly writing pencil of magnet suction principle, has following advantage:

1, because the basis of bed knife is the suction of magnet, so there is not the mechanical wear problem in stable performance, the life-span almost can endless;

2, no matter be to use at the beginning of, after still long-time the use, it is all relatively more consistent to get the required strength of pen, feel can be consistent;

3, scheme is simple, realizes that easily cost is low, is fit to very much vast handwriting input device and adopts;

4, the volume of magnet can be done smallerly comparatively speaking, and required locus is smaller.The shape of magnet also is simple column, is easy to processing and realizes.Because the column face that is magnet attracts contact mutually, so suction is bigger, relatively firmly.

Embodiment

Embodiment 1:

In the present embodiment, writing pencil 1 is to be inserted in the upper rail 3 of portable or pocket computer 2, is opposite with the direction of present most PDA penholder.Be fixed with a column strong magnets 4 with the same thickness of pen at the end of writing pencil 1, guide groove 3 bottoms also are fixed with powerful columnar magnet 5, two magnet 4,5 corresponding magnetic are opposite.

Embodiment 2:

In the present embodiment, writing pencil 1 nib inwardly inserts in the upper rail 3 of portable or pocket computer 2, is consistent with the direction of present most PDA penholder.Be fixed with a column strong magnets 4 with the same thickness of pen at the end of writing pencil 1, guide groove 3 ends also are fixed with powerful columnar magnet 5, two magnet 4,5 corresponding magnetic are opposite.

Embodiment 3:

Writing pencil 1 is to be inserted in the upper rail 3 of portable or pocket computer 2 in the present embodiment, is provided with strong magnets 5 on the middle part and the top of writing pencil 1, and is equipped with magnet 4 in the sidepiece and magnet 5 corresponding positions of guide groove 3.

Claims

1, a kind of pocket or palm PC, it is characterized in that: at the sidepiece of the guide groove (3) of placing writing pencil (1) or/and end (being top or bottom) is provided with a magnet (4), and at middle part or another magnet of top relative set (5) of writing pencil (1), and two the one side magnetic are opposite or identical relatively.

2, pocket or palm PC according to claim 1 is characterized in that: the optimum shape of magnet (4,5) is a column.
