Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable electronic device such as a book type computer or a word processor.

[0002]

2. Description of the Related Art Book-type portable computers are
It has the advantage that it is easy to carry and can be used freely even when out of the office where commercial power cannot be obtained by using the built-in battery pack as a power source.

This type of computer has a housing for supporting a keyboard and a flat panel type display unit. This case has a flat box shape,
A circuit board on which various circuit components are mounted and various functional components such as a floppy disk drive device and a hard disk drive device are collectively accommodated in the housing.

By the way, in recent computers, in order to facilitate handling when carrying the computer, it is required that the planar shape of the housing be as small as possible. For this reason, the space in the housing tends to become smaller and smaller, and therefore, there is a problem in how to accommodate a circuit board having a relatively large area in the housing. In order to deal with this problem, conventionally, the circuit board is divided into a plurality of pieces, and the plurality of divided circuit boards are stacked and arranged at intervals in the vertical direction, and flexible wiring is provided between the circuit boards. A computer having a configuration in which a board is connected has been developed.

In this computer, a plurality of circuit boards are bent at the wiring board portion, stacked in several stages, and supported in this state by a metal chassis. Therefore, the circuit boards are held in a posture in which they are stacked in several stages by the chassis, and are housed inside the casing together with the chassis.

On the other hand, there is known a portable computer which is easy to carry and has a high function, in which a memory card for increasing the storage capacity and an interface card for communicating with the outside can be mounted. A computer to which a card of this type can be attached has a card accommodation section inside a housing. The card storage portion is connected to a card insertion opening opened on the side surface of the housing, and the card is inserted and removed through the card insertion opening. Then, a connector to which the card is detachably connected is arranged at the end of the card accommodating portion.

In addition, an ejector for ejecting the card inserted from the card insertion slot is installed in the card accommodation portion. The ejector includes a pressing piece that faces the end of the card on the connector side, a push button that is arranged adjacent to the card insertion slot, and a linking mechanism that links the push button and the pressing piece. There is.

In this conventional ejector, when the operator presses the push button with the fingertip, the movement of the push button is transmitted to the pressing piece through the linkage mechanism, and the pressing piece is advanced toward the card. By this advance, the card is pressed in the direction of being detached from the connector, and the card is pushed out of the housing through the connector insertion port.

By the way, when the card is connected to the computer and used, the push button is accidentally pressed,
If the card is pushed out of the card housing, the information stored in the card may be erased or the correct information may not be stored. Therefore, there is known a conventional computer in which a lock lever is arranged at the opening end of the card insertion slot. This lock lever is slidably supported on the side surface of the housing between a lock position where it is advanced to the opening of the card insertion slot and hooked on the card, and a lock release position where it is retracted from the opening of this card insertion slot. Has been done. Therefore, if the lock lever is slid to the lock position, pushing of the card is prevented even if the push button is accidentally pressed during use of the card.

In a high-performance portable computer, a model equipped with a microphone for recording an operator's voice is known. Conventionally, a microphone is housed inside a housing, and the head of the microphone is exposed on the upper surface of the housing. In this case, most of the upper surface of the case is occupied by the keyboard, and the circuit board and various functional parts are housed inside this case at high density. , Keyboards, circuit boards and functional components are placed in the corners of the enclosure to avoid them.

The portable type computer has a convex portion projecting upward at the rear end portion of the upper surface of the housing. The convex portion extends over the entire width of the housing, and leg mounting portions formed of concave portions are formed at both left and right ends of the convex portion. Also, the display unit supported by the housing is
A housing for accommodating the liquid crystal display is provided.
A pair of left and right legs are provided to project from one end of the housing. These leg portions are inserted into the leg attachment portions, and are pivotally supported by the housing via hinge devices. Therefore, the display unit is configured to rotate about the hinge device as a fulcrum between a first position that covers the upper surface of the housing and a second position that stands upright with respect to the upper surface of the housing. .

The convex portion of the casing is located at the rear of the keyboard, and is continuous with the lower end of the display unit when the display unit is rotated to the second position. There is. Icons for displaying the operating status and the contents of functions of the computer are arranged in the portion from the front surface to the top surface of the convex portion.
The convex portion has a hollow shape continuous with the inside of the housing, and a plurality of LEs serving as light sources of the icons are provided inside the convex portion.
D and an icon substrate supporting these LEDs are arranged.

In addition to the icon board, various functional parts such as a sub-battery for setting a resume function, a cable led from a display unit, and a speaker are housed inside the convex portion. Each of these functional components is screwed to the inner surface of the convex portion, or is held on the inner surface of the convex portion via a dedicated bracket.

In a portable type computer, a keyboard is arranged on the upper surface of the housing. The keyboard has a flat keyboard panel and a number of keys supported on the top surface of the keyboard panel. Further, a keyboard mounting portion to which a keyboard panel is fitted is formed on the upper surface of the housing. The keyboard mounting portion has a rectangular frame-shaped seat portion that receives the peripheral edge portion of the keyboard panel, and a plurality of locations on the peripheral edge portion of the keyboard panel are tightened and fixed to the seat portion by screws.

[0015]

In the conventional portable type computer, a dedicated chassis is required to hold a plurality of circuit boards in a stacked posture. Therefore, the number of parts is increased by the amount of the chassis, which causes a problem of high cost and weight. Moreover, since it is necessary to secure a space for housing the chassis inside the housing, this may prevent the housing from being made compact, and there is still room for improvement in this respect. .

The conventional ejector mounted on the computer limits the movement of the card by the lock lever. Therefore, if you push the push button while the lock lever is sliding to the lock position,
The movement of the push button is transmitted as it is to the pressing piece via the linking mechanism, and the card is strongly caught between the pressing piece and the lock lever.

As a result, an unreasonable force is generated at the connecting portion between the card and the connector, which may damage the expensive card or connector. Further, since an unreasonable force is applied to the pressing piece that presses the card, the pressing piece may be deformed, and the function of the ejector may be impaired.

In a high-performance computer equipped with a microphone, the microphone is arranged in a corner of the housing in order to avoid a circuit board and functional parts arranged in the housing. Moreover, since the head of this microphone is exposed on the upper surface of the case, when recording information with the voice of the operator without inputting information through the keyboard, the emission direction of this sound and the direction of the microphone do not match. It may happen that the operator's voice cannot be recorded clearly. Further, since the housing in which the microphone is installed is placed directly on the table, when the microphone is turned on, for example, when a shock is applied to the table, there is a problem that noise accompanying the shock is easily picked up. .

In the portable type computer, the icon board and various other functional components housed in the convex portion of the housing are individually supported on the inner surface of the convex portion through dedicated screws and brackets.

According to this structure, a large number of functional components must be screwed to the inner surface of the convex portion one by one, so that the workability is poor and a great deal of labor and labor is required for assembling the computer. To do. Moreover, since a screw or a bracket is required for each one of the functional parts, the number of parts is increased, and it is necessary to provide a seat portion for receiving the screw on the inner surface of the convex portion, which complicates the structure of the housing, There are problems such as high cost and increased weight.

Further, in the case of the above construction, a screw or a seat portion for stopping each functional component may enter between the adjacent functional components on the inner side of the convex portion, and the screw or the seat portion interferes with the functional component. Cannot be narrowed.
Therefore, there is a problem that many functional components cannot be arranged at high density inside the convex portion having a limited width, and the mounting efficiency is reduced.

In the portable type computer, the keyboard arranged on the upper surface of the casing is fixed to the casing by screwing a plurality of peripheral portions of the keyboard panel to the keyboard mounting portion.

With such a structure, when the keyboard is fixed to the housing or, conversely, when the keyboard is removed from the housing, a special screwing operation is required, and it takes time to attach and detach the keyboard. In addition, since the seat portion for receiving the screw needs to be arranged in the keyboard mounting portion, the structure of the keyboard mounting portion becomes complicated. Therefore, there is a problem that the cost and the weight are increased together with the need for a plurality of screws.

The present invention has been made under such circumstances, and a first object thereof is to provide a plurality of circuit boards in a portable electronic device having a housing without using a special chassis or the like. It is possible to maintain the stacked postures, simplify the structure for supporting the circuit boards, realize cost reduction and weight reduction, and obtain a convenient structure for downsizing the housing.

A second object of the present invention is to prevent the card-shaped electronic component from being pushed out without applying excessive force to the card-shaped electronic component in a portable electronic device having a housing, and further, to eject the ejector. It is possible to easily identify from the outside whether the lock lever is in the locked state, and there is no need to secure a space for housing the lock lever inside the housing.
It is to obtain a structure that can realize the miniaturization of the housing.

A third object of the present invention is to provide a portable electronic device having a housing, in which the voice of the operator can be recorded efficiently and clearly, and moreover, the installation space for the microphone can be easily secured and the housing can be easily installed. It is to obtain a structure in which the wiring process of the cable between and can be performed easily.

A fourth object of the present invention is to provide a portable electronic device having a housing, in which a plurality of functional components can be collectively disposed inside the convex portion, which facilitates assembly and mounting. An object of the present invention is to obtain a structure in which efficiency can be improved, and further, screws, seats, and brackets for fixing individual functional parts are not required, and cost reduction and weight reduction can be realized.
