Field of invention

TECHNICAL FIELD The present invention relates to a back-loading input device, and more particularly to an input device for electronic equipment having a chassis with an operation interface attached to the rear side to facilitate quick input operation and reduce the size of the electronic equipment.

Description of the prior art

Among conventional electronic equipment with a complete keyboard that allows a user's finger to operate the keyboard to enter data, desktop computers, notebook computers, and some personal digital assistants (PDAs) are most widely used. These devices can provide fast text entry and e-mail responses in response to document processing. They are used to handle most office processes. However, they have a common limitation, that is, they must be placed on a flat workstation such as a desktop during data entry operations. Some portable electronic devices, such as PDAs or high end mobile phones, also have a small keyboard or virtual keyboard on the screen, or a touch control screen with character recognition. Such devices are portable and mobile and do not need to be placed on a flat panel workstation such as a desktop during data entry operations. They can be used anywhere and always share an office business. However, data entry speeds cannot match conventional computers or notebook computers.

As the technology of digital communication systems advances, mobile offices are becoming a new standard in many industries. But the desktop environment isn't always available anywhere. Providing fast data entry without a desktop is strongly required.

Summary of the Invention

In view of the foregoing, it is an object of the present invention to provide a back-loading input device for electronic equipment to facilitate the input operation and to reduce the size of the electronic equipment. The input device according to the invention can receive an input of a command for executing an operation of the electronic equipment and display it on the screen. This input device is at least:

Chassis;

An operation interface disposed in the chassis on the rear side that is not visible to the operator, and a screen displaying the operation results. The operation result is moved and arranged in a mirroring relationship with respect to the actual position and the operation direction of the operation interface referenced by the operator for executing the operation command of the electronic equipment. This operation interface is a keyboard. The result of this operation displayed on the screen is a keyboard table.

The electronic equipment described above is personal computers, PDAs, handsets, and other electronic equipment having a central processing unit for receiving text input.

The manipulation interface includes a plurality of button keys to enter accessible and operable characters or functions while the chassis can be grabbed using a user's finger. The screen can display the corresponding keyboard table. The position of the keys on the keyboard table mirrors the actual button keys of the operation interface on the back side. That is to say they are arranged on the same top and bottom, but on the left and right sides.

The screen has left and right keys on both sides to control at least the movement of the cursor and the selection of the screen.

The screen is also placed in the external electronic equipment independent of the chassis and connected to the chassis via wired or wireless manner. The chassis has a front surface printed with a keyboard table. The keyboard table has keys on the rear side at positions mirroring the actual button keys of the operation interface (namely, they are arranged on the same upper and lower sides, but opposite to the left and right sides). The input character or function of each button is marked for reference by the user during the input operation.

The operation interface of the present invention further has at least one cursor control means corresponding to the operation result displayed on the screen in the mirroring manner (same as up and down, but vice versa) to control movement or selection on the screen. This cursor control means can be a touch-sensitive pad, track ball, joystick, five-way button or the like or two touch-sensitive pads used in concert.

The keyboard table displayed on the screen is a key character table or key position map. The key is turned on by touching or pressing the finger, and turned off when the finger leaves the key or the key is pressed again.

The back-loading input device of the present invention further has an area held by the thumb held by the thumb or thumb muscle to withstand the weight of the chassis. It may include an extension plate extending from each of the two sides of the chassis.

The chassis may have further bracing racks on the rear side so that the chassis is placed on the desktop.

In one aspect, the keyboard of the present invention has an induction unit for detecting a touch position of a finger. This induction unit is a condenser or a resistive touch-sensitive pad, or a photo-resistive touch-sensitive pad. When a finger approaches or presses a button key, the keyboard table on the screen indicates the key corresponding to where the finger is placed and is indicated by a special mark, such as the color or pattern selected for the differential.

In another aspect, the keyboard of the present invention is a condenser or resistive touch-sensitive pad and has a display unit capable of determining coordinates. The surface of one button key may be divided into a plurality of segments, each corresponding to a selected letter or function.

In another feature, the button keys can be touched by the fingers to control the display and non-display of the keyboard table.

The foregoing, as well as additional objects, features and advantages of the present invention, are readily apparent from the following detailed description taken in conjunction with the accompanying drawings.

This front face has two faces, each having a region 111 and a screen 12 which are caught by the thumb, and an operation interface 14 which is arranged at the rear side 13 of the chassis 1 which is not visible to the operator. It includes a number of button keys 141 for entering letters or functions. This button key is disposed on the rear side of the chassis 1 that accesses and operates because the user's finger grabs the chassis 1. The screen 12 displays the operation result which is the keyboard table 120. The keyboard 120 has a key 120a corresponding to the actual button key 141 on the rear side 13 in the mirroring relationship.

The keyboard table 120 on the screen 12 mirrors the button keys 141, which are the same on the top and bottom sides, but vice versa on the left and right sides. By controlling one button key 141 or 142 on the chassis 1 (preferably at the front or side of the chassis 1 to facilitate pressure), the keyboard table 120 on the screen 12 is displayed or Or invisible. The keyboard table 120 may be a key character table or a key position map, and each button key 141 is marked by an input character or function. And each button key 141 represents a character having a different meaning or function according to different operating conditions.

The manipulation interface 14 also includes at least one cursor control means 143 and 144 for controlling the movement of cursor A on the screen 12 in a mirroring movement relationship (in other words, the same on the top and bottom sides, but vice versa on the left and right sides). . Referring to Fig. 3, when the finger moves from the point d1 to d2 (dashed line indicates the movement path) in the cursor control means 143, the corresponding cursor A on the screen 12 is mirrored (that is, the same on the top and bottom sides). However, on the left and right sides, it moves from point e1 to e2.

In another aspect, the manipulation interface 14 of the present invention also provides a touch-sensitive pad (see FIG. 2), track ball 145 (see FIG. 4), joystick 146 (see FIG. 5), or a five-step button ( 147 (see FIG. 6), which includes at least one cursor control means 143 and 144.
