Benefits of technology

Another object of the present invention is to provide an optical disk driver using a relatively simple loading mechanism, an operational processing apparatus having such an optical disk driver which is relatively small, and on which a display unit can be placed.
According to the present invention, the optical disk driver uses a top-loading mechanism in which an optical disk is inserted and / or ejected via the top surface of the second case. Therefore, the loading mechanism thereof is simpler than that using a front-loading mechanism so that the cost of the operational processing apparatus can be kept inexpensive. Moreover, the optical disk driver is united to the operational processor when the second case is located at the second position so that the operational processing apparatus is located in a relatively small space. Additionally, the first case is accommodated in the housing whereas the optical disk driver uses the top-loading mechanism so that a display unit can be placed on the housing.

Problems solved by technology

1. Since the CD-ROM driver 1 in FIG. 1 is coupled to the personal computer 2 via the interface cable 3, a relatively large space is necessary in which to locate the operational processing apparatus;
2. Since the CD-ROM driver 4 in FIG. 2 uses the top-loading mechanism, a display unit 5a cannot be placed on the personal computer 5;
3. Since the CD-ROM driver 6 uses the front-loading mechanism which is more complicated than the top loading mechanism, the cost of the operational processing apparatus becomes more expensive.

first embodiment

A description will now be given of a CD-ROM driver and an operational processing apparatus having such a CD-ROM driver therein of a first embodiment according to the present invention with reference to FIGS. 4 to 6. Same elements will be designated by the same corresponding reference numerals, and the description thereof will be given once.

The operational processing apparatus 10 according to the present invention comprises a housing 10a, a personal computer (not shown) accommodated in the housing 10a, an accommodation case 12 accommodated in the housing, and a CD-ROM driver 11 insertable into the accommodation case 12 and / or projectable therefrom.

The CD-ROM driver 11 drives a CD-ROM 13 when the CD-ROM driver 11 is inserted into the accommodation case 12. Therefore, it may be said that the CD-ROM driver 11 accommodated in the accommodation case 12 corresponds to the CD-ROM driver 1 shown in FIG. 1. The CD-ROM driver 11 is projected from the accommodation case 12 when the CD-ROM 13 is...

third embodiment

It is possible to move the CD-ROM driver automatically from the second position to the first position, and thus open the lid in synchronization with the release of the latch mechanism. A description will now be given of an operational processing apparatus of a third embodiment according to the present invention with reference to FIGS. 8 to 10. The operational processing apparatus 30 of the embodiment comprises a projection mechanism 34, a spring 27 which forces a lid 28 in an opening direction (direction A), a lock mechanism 23, and a lock release mechanism 40. In this embodiment, the lid 28 has a hook 26. The hook 26 is engagable with the lock mechanism 23 to lock the lid 28 in order to keep the lid closed. The spring 27 is engaged with the axis 22.

The projection mechanism 34 is a mechanism for automatically moving the CD-ROM driver 29 from the second position to the first position in synchronization with the release of the latch mechanism. The projection mechanism 34 comprises a p...

fifth embodiment

FIG. 14 shows a CD-ROM driver 60 of the fifth embodiment according to the present invention. The positioning members 52 and 53 have square pillar shapes made of synthetic resin, respectively, top surfaces which project from the top surface 12d by "a", bottom surfaces which project from the bottom surface 12e by "b", side surfaces which project respectively from the side surfaces 12f and 12g by "c" and by "d", as shown in FIGS. 15 to 17. The spans "e" of the positioning members 52 and 53 are equal to the height "f" of the mouth 51 and the height "i" of the front part 14a. The distance "g" between the side surfaces 52c and 53c is equal to the width "h" of of the mouth 51. The width "j" of the front part 14a is equal to the distance "k" between the top surfaces 52a and 53a.

FIGS. 18 and 19 show the accommodation case 12 accommodated in the housing 60a. The top surfaces 52a and 53a make contact with the top surface 51a of the mouth 51, the bottom surfaces 52b and 53b make contact with th...

Abstract

An optical disk driver using a top-loading mechanism is coupled to an operational processor, such as a personal computer. The term "a top-loading mechanism" means a mechanism for inserting and / or ejecting an optical disk via a top surface of the optical disk driver. Additionally, a display unit used for the operational processor can be located on an operational processing apparatus comprising such an optical disk driver and an operational processor. The optical disk driver includes a first case (12), accommodated in a housing (10a) having the operational processor therein, a second case (11); movable from a first position to a second position, the second case (11) projecting from the first case (12) so that an optical disk can be inserted and / or ejected via a top surface of the second case (11) when the second case being located at the first position, the second case being accommodated in the first case to be operatively connected to the operational processor when the second case (11) being located at the second position.

Description

BACKGROUND OF THE INVENTIONThe present invention relates generally to optical disk drivers which drives optical disks (generally called CD-ROMs) and operational processing apparatuses having such optical disk drivers therein, and more particularly to an optical disk driver using a top-loading mechanism and an operational processing apparatus having such an optical disk driver therein. The term "a top-loading mechanism", as used herein, means a mechanism for inserting and / or ejecting an optical disk via a top surface of the optical disk driver. And the term "an operational processing apparatus", as used herein, means an apparatus having an operational processor, such as a personal computer, and a CD-ROM driver.FIGS. 1 to 3 shows example of different types of CD-ROM drivers. FIG. 1 shows a CD-ROM driver using the top-loading mechanism separated from a personal computer. FIG. 2 shows a CD-ROM driver having the top-loading mechanism united with a personal computer. FIG. 3 shows a CD-ROM...
