Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an electronic device equipped with a storage device, a display device, etc., and particularly a personal computer, word processor, or console equipped with a small, handy, and easy-to-use liquid crystal display device, etc. The present invention relates to an electronic device having a mounting structure suitable for devices and the like.

[Background of the invention]

More recently, storage devices have become smaller and lighter, and large-screen liquid crystal display devices have become more practical.
BACKGROUND ART The development and commercialization of portable and handy electronic devices such as small personal computers, word processors, and console devices that are equipped with liquid crystal display devices and the like are rapidly progressing.

However, when conventional devices that have already been commercialized are examined from various angles regarding their mounting structure, assembly configuration, operating method, etc., the following various problems can be pointed out.

(1) Regarding the mounting structure and operation method of storage devices in conventional devices, the number of storage devices installed is 1 to 2, and the operation to install and remove the storage media is performed from the top side or from either the left or right side. It was a method. For this reason, especially in devices equipped with two storage devices, (1)
If the operation method is to insert or remove the media of the storage device from one side of the storage device, there is a high risk of misplacing the media in the device.
(In a structure in which il storage devices are mounted in two stacks, the height of the device becomes large; (ii) in a structure in which D storage devices are mounted in a row in the front-back direction, the depth dimension increases, In addition to increasing the flat area, it also makes it difficult to attach/remove/replace media on the rear side.Ov) Storage devices are generally heavy, so a mounting structure that is lopsided on one side will reduce the weight of the device and make it difficult to balance. There are problems such as not being suitable for use as equipment.

(2) In the conventional assembly configuration in which the storage device is attached directly to the main body case, (1) the shape of the main function printed wiring board becomes complicated, which is not desirable from the viewpoint of mounting density of the printed wiring board; Installation requires separate parts such as metal fittings, which increases the number of parts.
(ii! 1) Since the storage device and the main function printed wiring board cannot be treated as an integrated partial assembly, there are problems such as poor assembly workability and poor maintenance.

(5) Due to the mounting structure in which the input device cannot be attached or detached, (
1) When trying to use it in a neat position, the entire device is placed on the lap, which makes it heavy and difficult to operate, and the expensive device may fall and break, making it inconvenient to use (11
)There are few freedoms and many restrictions regarding work posture and desk placement, etc.(lli)There are problems such as the inability to freely change and use various input devices corresponding to various uses. .

(4) Since the angle of the position of the operation surface of the input device cannot be adjusted, there is a problem that the input device cannot be used in a comfortable posture and the user is not very helpful.

(5) If you attempt to configure the input device to be detachable, if the cable connected to the main body is pulled out in the wrong position or method, the cable will be exposed when the input device is attached, making it difficult to handle the device. This poses problems such as being a hindrance and having an undesirable appearance.

(6) If you try to configure the input device to be detachable,
If you do not consider the cable storage method mentioned above, the cable may leak out of the device when the input device is attached to the main body.
This poses problems such as being difficult to handle, undesirable in appearance, and increasing the size of the device for housing the cable.

(c) If the angle of the display screen cannot be adjusted freely during the lighting stage, the display will be difficult to see, especially in liquid crystal display devices, which will cause problems in use.

However, the conventional device (:) adjusts the angle of the display surface in stages and cannot perform stepless adjustment, and (11) attempts to reduce the size of the hinge mechanism, making it mechanically weak.
(iii) Furthermore, the hinge mechanism becomes large, which is undesirable from the viewpoint of external structure, and there are other problems such as the Gvl hinge mechanism becoming complicated and expensive.

(8) In the main body side configuration, if the power supply section such as batteries and converters and the main function sections such as main function printed wiring boards and storage devices are not configured so that they can be separated as sub-assemblies, (1) There are problems such as poor assembly workability, (11) poor maintainability, and (011) complicated structure.

(91) It is better to provide a protective cover for the connector section for connecting external devices in order to protect the connector and improve its appearance. However, conventional devices have a complicated structure, are not easy to operate and use, and are not good in terms of appearance. There are problems such as:

(10) Regarding the configuration method of the display device section, (1
) The assembly structure is complicated, (11) many screws are used, and (ili) there are problems such as the stacking assembly method does not have good assembly workability.

(11) In the configuration method of the input device, (1) assembly time is required, (11) screws are visible from the outside, and (iii)
) The number of parts was large, (IVI) it was difficult to construct a thin structure, and (■) it was difficult to construct a compact structure.

[Purpose of the invention]

The purpose of the present invention is to solve the various problems of the prior art described above, and to provide an electronic device equipped with a storage device, a display device, etc., which is small, lightweight, easy to assemble, inexpensive, and easy to use. be.

The power switch 8 is inserted into and engaged with a power switch mounting hole provided on the side wall of the main body side case 1. Holes C provided on the left and right walls of the main body case 1 are holes for mounting media into the storage device 2. Further, a connector for connecting external equipment, which will be described later (FIG. 5), is arranged at the rear end of the main function printed wiring board 5. Since these external device connection connectors and lids are exposed outside the case, connector protection covers 9 are placed behind the left and right side walls of the case 1 on the main body side to protect the connectors and give the device an elegant appearance. It engages with the main body case 1 by a hinge provided at the end or rear wall. In this example, round holes 2 are provided at the rear ends of the left and right walls of the case 1 on the main body side, and the holes 2 engage with the holes provided at the upper parts of the left and right side ends of the connector and lid protective cover 9, thereby protecting the connector.

Further, a tongue connector 15 for connecting an input device to be described later is attached to the center of the main body side cover 10, and the lid is attached from the piece 141C. In the center of the main unit cover 10 to which the connector 15 is attached, there is a U-shaped groove into which the input device connection cable is drawn, and a claw for cable clamping is provided at an appropriate position in this groove. This allows the cable to be fixed without floating up.

In addition, the front side of the main body side cover 10 descends in a step-like manner,
A keyboard input device, which will be described later, is attached to this stepped portion. Furthermore, the very front part is sloped down, and this sloped part forms a gap in which the cable of the input device is housed. Top 1 The recess provided in the step-like step of the main body cover 10 is connected to the input device case 1.
The input device is used by taking out the elastic claw provided on the rear wall of 5 and engaging the input device when it is stored and attached to the main body, and engaging it with the front wall of the case on the main body after taking the input device out of the main body. The protrusion part O, which is integrally formed with the protrusion part for the purpose of the present invention, is configured to fit together. Note that the main body side cover 10 can be attached to the main body side case 1 from above using mounting screws.

The key switch unit (assembly) 16 of the input device is housed and assembled from above into the input device case 15 formed in a concave shape. B
is directly attached, and there is no metal mounting plate for attaching the key switch as in conventional key switch unit assemblies. This is to make the keyboard input device as thin and lightweight as possible as a handy device. The key switch unit assembly 16 is housed and fixed in the input device case 15 by attaching the keyboard unit printed wiring board A to the input device case 15 using mounting screws 17. This addition is installed in a position away from the installation position of key switch B, but since the mounting screw 17 cannot be tightened with the key switch cap C installed, the key switch is located around the installation screw hole position. Cap C
