Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a portable electronic computer used for a variety of purposes.

[Prior art] A typical desktop personal computer uses a CPU
Electronic circuits such as memory circuits, including memory circuits, are fixed to the frame itself, or boards are inserted through connectors, and magnetic floppy disks and hard disk drives do not need to be attached and detached frequently, so they are fixed to the frame body and used at all times. The configuration was such that everything was built into a fixed housing, and optional circuit boards were inserted from the back of the housing as needed.

In addition, in portable personal computers that have been put into practical use in recent years, especially laptop-type computers, the floppy disk drive is placed on the side of the x-body in order to make them smaller and thinner. Since media is taken in and taken out from the side, operations are performed in an area that is invisible to the operator.

This is of course inconvenient, but there are few advantages, such as damage to the media, operational errors, or the inability to check whether or not access is occurring.

Furthermore, since the hard disk drive and the frame body are fixed with screws or the like, the configuration makes it impossible to easily replace a part of the device.

[Problems to be Solved by the Invention] The purpose of the present invention is to provide a small personal computer that is portable yet easy to operate, completely changing the concept of the conventional configuration. The system is ergonomic, with a front-loading magnetic disk being operated by a front-loading operator, and a large-capacity magnetic disk, which is used relatively infrequently, placed at the rear of the display, and unitized devices can be attached and detached at will. This objective is partly achieved by providing a device that is easy to use, eg with frequently operated parts slightly tilted.

[Means for Solving the Problems] The present invention includes a hinge portion of a display body at one end of the device body, a front-loading first media drive portion at the other end of the body, and a hinge portion at the front portion of the body. The present invention is characterized in that a second media drive section is provided behind the keyboard section arranged as a palm and the hinge section.

FIG. 6 is a perspective view of the main body upper case 1 and the drive case 3 assembled with the above structure except for the cover 2 in a fixed state.

FIG. 7 is a schematic diagram showing the shape of the groove 4-b provided on the bottom side of the lever 4, and shows the center point 6-c of the shaft 4-d of the lever 4.
Arcs 67a and 6-b, which are part of the circumference centered at , and arc 8-a centered at a point 6-e different from point 6-c.
An arc 6-d that is continuous to the arc 6-d and has a radius larger than the arc 6-a.
The arc 6-f is centered on a point 6-g on a line connecting points 6-c and 6-e, and has a radius larger than the arc 6-d. The radius of the circular arc 6-b is longer than the radius of the circular arc 6-a by an amount corresponding to the width of the protrusion 3-a on the top surface of the drive case 3.

FIG. 8 is a schematic diagram showing the principle of operation when the drive case 3 is attached and fixed. When installing the drive case 3, first, the lever 4 is rotated so that the notch 5-d of the guide frame 5 and the opening 4-b on the bottom side of the lever 4 are aligned.

Next, the drive case 3 is inserted through the opening of the guide frame 5. The protrusion 3-a on the top surface of the drive case 3 is
When the lever 4 is rotated in the direction of the arrow when the groove 4-b of the lever 4 contacts the side surface of the circular arc 6-f, the side surface of the circular arc 6-d of the groove 4-b comes into contact with the protrusion of the drive case 3. 3-a,
Pushing in the insertion direction, the drive case 3 is inserted into the guide frame 5. Further, the above insertion can also be performed by pushing the drive case 3 in the insertion direction, and the lever 4 rotates as the drive case 3 is inserted.

The protrusion 3-a of the drive case 3 is connected to the groove 4-b of the lever 4.
The operation of inserting the drive case 3 ends when the drive case 3 touches the arcs 6-a and 6-b.

By roughly rotating the lever 4 in the direction of the arrow from the above-mentioned position, the protrusion 3-a of the drive case 3 is
It contacts only the arc 6-a16-b of the groove 4-b of the lever 4. Since the arcs 6-a and 6-b are concentric circles with respect to the center of rotation of the lever 40, even if force is applied to the drive case 3 in the insertion direction and the removal direction, the lever 4 will not rotate. The drive case 3 is fixed at a predetermined position by fixing the lever 4 by fitting the protrusion 15-c of the lever frame 5 with the notch 4-e of the lever 4.

When taking out the device, place your finger on the protrusion 4-a of the lever 4 and rotate the lever 4 in the opposite direction to when it was inserted.

When the groove of the lever 4 pushes the protrusion 3-a of the drive case 3 in the opposite direction to the direction of insertion, removal is performed.

FIG. 9 shows a floppy disk drive (F) according to the present invention.
DD) section 23 and a power supply section 44 are sectional views.

1 is an upper case, 24 is a keyboard, 38 is a CPU (central control unit) board, 39 is a lower frame, 40 is a ■0 board, 41 is an upper frame, and 43a, 43b, and 43c are boss parts. 45 is a member for installing the FDD, and 46 is an inclined part of the upper frame that is set to make it easy to insert and remove a floppy disk, and is inclined at about 4 degrees with respect to the horizontal direction.
Particularly in portable information devices, if a Freon I-coding type FDD is provided with a slight inclination of about 2 to 8 degrees, handling is much easier than if it is installed horizontally.

The keyboard section 24 is inclined at an angle of about 8 degrees in the opposite direction above the FDD section 2, and from the viewpoint of operability, the keyboard section 24 is inclined at an angle of 4 degrees to 15 degrees.
When placed facing each other at an angle of 57 degrees to 174 degrees, the information device becomes easy to operate.

FIG. 10 is a sectional view centered around the hinge section 34 and hard disk drive (HDD) section 31 of the display device according to the present invention. 1 is the upper case, 32 is the HDD upper case,
33 is the HDD upper case, 35 is the display lower case, 36 is the display upper case, 37 is the lower frame, 21 is the lower case,
3B is a CPU board, 39 is a lower frame, 40 is an IO board, 41 is an upper frame, and 42 is an option board lid.

The hinge part is located at one end on the left side when viewed from the operator, and the magnetic disk drive is located at the other end, so when the display is lifted and set at an appropriate position for easy viewing, the display is almost in the same plane as the disk drive, making it easy to operate. This hinge part could have the disk on the right end and the disk on the left end, but since there are many people who are right-handed, the disk is on the right side.

Regarding magnetic disks, if a 3.5-inch medium is used for the FDD section and a 2.5-inch hard disk is used for the HDD section, the FDD section 23 will be replaced by the HDD section 31 in Fig. 10.
The FDD section can be inserted into the HDD section and used as a card-shaped unitized optional body.

In this case, if the receiving and stopping connectors are not common, separate connectors may be provided depending on the direction of insertion, or switching may be performed using an all-electronic switch.

[Effects of the Invention] According to the present invention, the functions of a personal computer can be maximized, and the structure is mechanically space-efficient, so there are various effects in terms of manufacturing and after-sales service. This idea can be commonly applied to information devices in the same field.

In addition, the drive mechanisms for magnetic storage devices and other devices are unitized and can be easily expanded or replaced, expanding the functionality of the product, providing after-sales service, individualized data management, and allowing only the drive parts of the main unit to be replaced. It is something that you have.

In addition, by using the rotating lever shown in the embodiment, it is possible to attach and detach the device with continuous smooth movement, which is particularly useful in cases such as hard disks where consideration must be given to shocks.
