Abstract

PURPOSE:To suppress a disk from being damaged, to facilitate packaging of a power unit, etc., and also, to miniaturize the processor by opposing each back of two disk unit, allowing its longitudinal direction to coincide with the longitudinal direction of a keyboard unit and placing them under the keyboard unit. CONSTITUTION:A hard disk drive (HDD) 20 and a floppy disk drive (FDD) 30 are placed by setting the longitudinal direction of the HDD 20 and the FDD 30 to the same direction as the longitudinal direction of a housing so that they are held almost completely in the lower space of a keyboard unit 40. Also, they are placed back to back so that a connector of the HDD 20 and the FDD 30 becomes the vicinity of the center of the housing 10. In such a way, installability of the disk is maintained, a misoperation of an eject button and damage of the disk caused by refuse, etc., are suppressed, and also, packaging of a power unit is facilitated, and the processor can be miniaturized.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a portable information processing device that is small and portable, and particularly relates to a portable information processing device in which two disk units and a keyboard unit are housed in the same housing. Regarding what is being done.

[Conventional technology]

Currently, various offices are transitioning to a new office format due to the movement to improve the workplace environment, against the backdrop of a desire to improve the quality of life.

In addition, under these circumstances, the Ministry of International Trade and Industry's Daily Goods Review (April 1988) states that office planning in recent years has been designed to bring out creativity and promote efficient work. We believe that it is important to create a functional and comfortable place to live.

Therefore, in recent years, in order to effectively utilize the space on an office desk and in consideration of portability, portable information processing devices called laptop personal computers and book-type personal computers have become popular.

Among these portable information processing devices, those equipped with two disk units include, for example, a board unit disposed below a keyboard unit, and a power supply unit and two disk units disposed behind these. There are some that house these in the same housing.

However, in such a portable information processing device, since the disk unit is located at the rear of the housing, it is difficult to mount a floppy disk, making it inconvenient to use.

Therefore, there is a system in which a disk unit is placed directly below the keyboard unit placed at the front of the housing, with the floppy disk loading port of the disk unit facing forward.

[Problem to be solved by the invention]

Generally, when a portable information processing device is carried or stored, the front surface of the casing often faces upward.

By the way, in the prior art, since the floppy disk mounting opening of the disk unit faces forward, it is easy for dust and the like to enter the disk unit with the floppy disk facing upward when being carried. Additionally, if the floppy disk eject button is touched while performing key operations, the disk being accessed may be ejected from the disk unit. As described above, conventional portable information processing devices have the problem that dust gets inside the desk unit and the disk being accessed often comes out of the disk unit, which can damage the disk. .

Furthermore, in the conventional technology, since the longitudinal direction of the disk unit faces the front-rear direction of the housing, there is a large dimensional difference between the longitudinal dimension of the disk unit and the front-rear dimension of the keyboard unit, that is, the depth dimension. If the keyboard unit is stacked on top of the unit, a large level difference will occur, making it difficult to mount the disk unit and the power supply unit provided behind the keyboard unit, and making it difficult to downsize the unit.

The present invention has been made by focusing on these conventional problems, and it is possible to maintain the ease of mounting a floppy disk, reduce damage to the disk, and easily mount a power supply unit, etc. An object of the present invention is to provide a portable information processing device that can be downsized.

Another object of the present invention is to provide a disk unit suitable for a portable information processing device that achieves the above object.

[Means for Solving the Problems] A portable information processing device for achieving the above object is a portable information processing device in which two disk units and a keyboard unit are housed in the same housing.
the two disk units facing each other with their backs facing each other;
The keyboard is characterized in that its longitudinal direction is aligned with the longitudinal direction of the keyboard unit, and the keyboard is disposed below the keyboard unit.

Here, it is preferable that an indicator indicating whether or not the disk unit is moving is provided on a surface forming the casing where key tops of the keyboard unit are exposed.

Further, it is preferable that the disk unit is fixed to the bottom of the housing.

The disk unit for achieving the other purpose is a floppy disk unit housed in a housing of an information processing device, in which an indicator indicating whether or not the floppy disk is being accessed is exposed from the top surface of the housing. It is characterized in that it is provided on the upper surface side.

[Effect]

By arranging the disk unit under the keyboard unit, the disk unit is located close to the operator's hand, so that the ease of mounting the disk can be maintained.

Furthermore, since the longitudinal direction of the two disk units is aligned with the longitudinal direction of the keychain unit, the floppy disk loading slot and floppy disk eject button are on the side, so when the device is stood up, the floppy disk loading slot is visible. It does not face upwards, making it difficult for dirt to enter the disk unit through the loading slot, and also eliminating the possibility of accidentally touching the eject button while operating keys, allowing the disk being accessed to be ejected from the disk unit. You can prevent it from getting stuck.

Therefore, damage to the disc due to incorrect operation of the eject button, dust, etc. can be reduced.

By aligning the longitudinal direction of the disk unit with the longitudinal direction of the keyboard unit and placing them one above the other in the housing, the front-to-back dimension of the disk unit and the front-to-back dimension of the keyboard unit are approximately 8- Therefore, the difference in level between the disk unit and the keyboard unit can be reduced, and it becomes easier to mount the power supply unit and the like provided behind the disk unit and the keyboard unit, and the size can be easily reduced.
