Description

The operated security password keyboard of thumb

Technical field

The present invention relates in bank, the supermarket, when economic activity is carried out in places such as card volume, to bank, supermarket, the code keypad of the computing machine input account password of card volume company etc.

Background technology

At present, known code keypad has each button, and the edge of keyboard is with baffle plate and causes password to reveal to prevent to be peeped by others.This known code keypad is to allow forefinger (be aided with the once in a while middle finger nameless little finger) button of human hand in use.But because of the staff structural reason, can only first three side add baffle plate in the left and right sides at most, the baffle plate that wherein is added in the left and right sides again can not be high, otherwise can make hand be confined to a narrow space and the mobile of hand limited to.So, enough height that the baffle plate on the known code keypad can't be done, the especially sight line or the supervision of eminence around can not effectively blocking far away, dangerous when using keyboard input password, cause peep of cipher to reveal easily.

Summary of the invention

In order to overcome the weak point of existing various password keypads, the invention provides a kind of new method, this method can not only be blocked keyboard and sight line or supervision all around effectively, and the actuation of keys of hand is not subjected to too big restriction during input.

The method that head it off of the present invention adopted is: narrowing down to 15 to 40 square centimeters of areas in each key sets of code keypad, prop by base, enclose on three limits of code keypad that three faces are made baffle plate and open wide on one side, add above a face that has a viewing window and with three seamless fusions of face doing baffle plate, allow viewing window place face extend and constitute baffle plate.

The invention has the beneficial effects as follows that the space of enclosing only need hold the thumb flexible operating of hand, rather than the space that holds whole hand on the cryptographic key card, so volume is small and exquisite and it is safer more to seal, sight line or supervision around stopping effectively.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is the novel front view of this use.

Fig. 2 is a right view.

Fig. 3 is a front view.

A among Fig. 1 Fig. 2 Fig. 3 is a base, and G is the keyboard face, and F is the form actinal surface, and B, C, D, E all are baffle plates

B, C and three baffle plates of D are enclosed in three limits of keyboard face G, add above a face F who has a viewing window and with three seamless fusions of face doing baffle plate, viewing window place face extends to form the E baffle plate.

Embodiment

During button operation, the tiger of the right hand up, the palm of the hand is towards a left side, stretch between baffle plate E and the base A, thumb enters by three baffle plates of BCD and the common space that surrounds of keyboard face G (hereinafter to be referred as the space) from the right side of opening wide, eyes are watched thumb and keyboard face G down attentively from the top viewing window, press the button on the G face one by one while seeing.The palmar hand that does not enter the space is blocked by the E baffle plate, makes hand motion more hidden, and the nameless little finger of the forefinger middle finger of hand does not stretch in the space, is placed on G face downside, can cooperate the thumb application of force.

Claims

1. operated security password keyboard of thumb, has each button, the edge of keyboard is with baffle plate, it is characterized in that: narrowing down to 15 to 40 square centimeters of areas in each key sets of code keypad, prop by base, enclose on three limits of code keypad that three faces are made baffle plate and open wide on one side, add above a face that has a viewing window and with three seamless fusions of face doing baffle plate, allow viewing window place face extend and constitute baffle plate.
