Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a keyboard device for a portable device such as a personal computer that is equipped with a keyboard. (b) Prior Art In general, most personal computers are of the stationary type, and apart from this, the so-called handheld type has a display system using a liquid crystal display (LCD). In recent years, portable CRT display type personal computers using small cathode ray tubes have begun to be adopted, and as an example, as shown in U.S. Pat. A method of closing the lid has been proposed. However, in the above-mentioned example, a protrusion is simply provided on the keyboard, a latch means is provided on the body of a personal computer (hereinafter abbreviated as PC), and the front side of the PC body is closed. The piece remains protruding all the time, and the PC
Since the latch means is separately attached to the main body, the protrusion not only becomes an obstacle when the keyboard is used, but also has the disadvantage of increasing the number of parts. (c) Purpose of the invention The present invention is designed to minimize the number of parts that can be used to fit the locking piece into the recess using the operating section when the keyboard is integrated into the PC board by simply providing a recess on the PC main body side. It is an object of the present invention to provide a keyboard device for a portable device that can be reduced in size. (d) Structure of the invention The present invention provides an electronic device that is housed with the keyboard surface facing the front of the cabinet main body of a portable device. A locking piece is provided inside the keyboard and moves accordingly and fits into a recess provided in the inner wall of the front surface of the cabinet main body. (E) Embodiment The drawings all show a keyboard device for a portable device of the present invention, and FIG. 1 is a perspective view of an embodiment of the device used in a personal computer.
2 is a perspective view of a main part showing the back side of the keyboard in FIG. 1, and FIG. 3 is a sectional view of a main part of the keyboard. In the drawing, 1 is the main body of the cabinet.
The main body of the PC, 2 is a cathode ray tube, 3 is a floppy disk unit, 4 is a keyboard, 5 is an operating unit, 6 is a locking piece, 7 is a spindle, 8 is a moving lever to which the locking piece is attached, 9 is a corresponding a rotation shaft on which the moving lever is supported and rotated; 10 and 11 are protrusions provided integrally with the operating portion; 12 is a protrusion abutting the protrusion; 1;
Reference numeral 3 denotes a notch provided in the operating section for inserting and pulling out a finger. Now the state shown in Figure 1 is that the keyboard 4 is connected to the PC body 1.
If you want to integrate it into the PC main body 1 after removing it from the PC, insert your finger into the notch 13 of the operating section 5 , raise the operating section 5 as shown in Figures 2 and 3 A, and move it in the direction of arrow A. , the protrusion 11 comes into contact with the protrusion 12 of the movable lever, and the movable lever 8 moves in the direction of arrow C, and the locking piece 6 engages the keyboard 4.
In this state, the front surface of the cathode ray tube is closed using the key switch side K of the keyboard 4 .
In this case, when the operation parts 5 , 5 provided on the bottom surface of the keyboard 4 on the front inner wall of the PC main body 1 are rotated in the direction of the arrow B shown in FIGS. 2 and 3, the moving lever 8 is moved in the direction D. At the same time, the locking piece 6 is connected to the keyboard 4.
Since the locking piece 6 protrudes from the side surface of the PC main body 1, the locking piece 6 fits into the recess 12 of the PC main body 1, and the keyboard 4 is held integrally with the PC main body 1. On the other hand, if you wish to remove the keyboard 4 from the integrated PC main body 1 , contrary to the above, insert your finger into the notch 13 of the operating section 5 and pull it out in the direction of arrow A in FIG. 2 or 3. The protrusion 11 of the portion 5 comes into contact with the protrusion 12, the moving lever 8 moves in the direction of arrow C, and the locking piece 6 is placed in the state shown in FIG. When using the keyboard 4 , if the operation unit 5 is pulled out from the bottom of the keyboard 4 in the state shown in FIG. 4
The rear side R can be set high and a so-called tilt effect can be obtained. As described above, when the keyboard 4 is integrated into the PC main body 1 and carried around, the front of the cathode ray tube 2 and floppy disk section 3 can be covered, and the key switch side of the keyboard 4 also has the cathode ray tube 2 and floppy disk section 3. The key switch of the keyboard 4 is also protected because it faces the front of the section 3. Furthermore, if the operating section 5 is pulled out from the bottom of the keyboard 4 , the back of the keyboard 4 can be raised higher, making it easier to operate. (f) Effects of the invention According to the keyboard device for a portable device of the invention, when the front side of the cabinet body, for example, the cathode ray tube and floppy disk part of a portable personal computer, is covered with the keyboard, the operation part is simply closed. Not only can it be rotated easily and the number of parts is reduced, but it can also be constructed from a molded product made of synthetic resin, and when the keyboard is used, the locking pieces do not protrude from the side of the keyboard and get in the way. It will never become. Also, as a side effect, by pulling out the operation section,
When using the keyboard, the back side can be raised higher, making it possible to use a so-called tilt method.
