Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medium drive device having a medium insertion opening on the front surface and having a substantially rectangular parallelepiped outer shape.

[0002]

2. Description of the Related Art FIG. 6 is a perspective view of a conventional medium drive device (disk drive device), and FIG. 7 is a block diagram for explaining the operation of FIG.

Conventionally, the medium such as the disc 62 and the card of the disc drive device 61 or the card reading device is operated while it is completely contained in the device. Therefore, the disc 61 and the card are inserted during this operation. The user cannot easily check whether or not
Even if you can confirm it, it is a structure that you can not take it out immediately.

For example, in the case of a conventional floppy disk device, it can be visually confirmed that a floppy disk is loaded. However, when the medium is ejected, it is confirmed that the drive device is not operating and the eject button 64 is pressed to eject the medium. It is designed to be discharged. However, in either of these cases, the user of the apparatus checks the presence of the medium 62 such as a disk or a card, and then pushes the eject button 64 to take it out and carry it. The reason for this is that the device is completely loaded into the device to allow read operations to improve drive performance or card read accuracy. It is also for preventing the medium 2 from being suddenly removed.

[0005]

However, in consideration of the convenience of the user, it is easier to confirm and take out the medium such as the disk or the card when the medium is projected outward. Further, it is considered that the disk drive device and the card reading device, which are originally intended to be taken out and carried, should have a safety mechanism when the medium is taken out. Further, it is considered that the volume of the apparatus can be reduced by partially protruding the medium.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of an embodiment (disk drive device) of a medium drive device according to the present invention, and FIG.
FIG. 3 is a block diagram for explaining the operation of FIG. 1, and FIG. 3 is a plan view showing a schematic configuration of the mechanical device section of FIG.

As shown in FIG. 1, the shape of the apparatus is clear.
The disk drive device 1 is basically provided with only a disk insertion port 3 on the outer front surface for inserting a disk (medium) 2. Then, the medium 2 is placed so as to protrude from the drive device 1 for the medium 2 by an appropriate distance. That distance
Is at least considering the thickness of the medium and the ease of picking with your fingertips.
Is also considered to be 10 mm.

Next, the configuration of the device of the present invention will be described with reference to the block diagram of FIG. 2. The disk controller 11 for controlling the entire drive device is a controller unit 1.
It is built in 6 and controls data, read /
A data control circuit 12 for controlling the write cache 9 and an interface unit 10 are connected. Further, the controller unit 16 controls the motor control circuit 8 and the head controller 7.

Further, a pull-out sensor 6 which is an important element of the present invention, for judging whether the medium is inserted, is in a waiting state for ejection, or is in an inserting operation or an ejecting operation, is provided. , And is connected to the disk controller 11 and arranged in the machine unit 4.

Next, the construction of the mechanical device section 4 will be described with reference to FIG. The structure of the machine unit 4 is shown in a projected plan view.

The mechanical device section 4 is composed of a medium placing section 19 for supporting the medium 2, a pull-out sensor 6, a lateral sensor 17 and a vertical sensor 18 attached thereto. Sliding pieces 19a are provided on both the left and right sides of the medium mounting portion 19, respectively. The user removes the media
In order to prevent the medium 2 from slipping out immediately when an attempt is made, it has a structure in which it has a mechanical friction or mechanical load resistance and is sandwiched and slid in the grooves 20 provided on both sides.
Outer U-shaped portion of the medium placing portion 19, a guide was used to state the drive disk (medium) 2 has projections on the outer side. Further, in order to detect vibration, a horizontal sensor 17 and a vertical sensor 18 are attached.

The operation of this embodiment will be described below.

When the medium 2 is inserted after the host computer 13 is started, the disk controller 11 first tries to maintain the read state. The disk controller 11 detects the insertion of the medium with the pull-out sensor 6, and uses the vertical direction sensor 17 and the horizontal direction sensor 18 to detect the medium placement section 19
When it senses that there is no vibration, the motor controller circuit 8 is instructed to rotate the motor 15, and the state in which the signal can be read from the read head is maintained. In this case, the user of the host computer 13 cannot determine which data of the medium 2 is to be read or written, so that data prefetching is not performed. Next, when there is a request for some kind of read data, the data control circuit 12 reads the data via the interface unit 10, and at the same time, a copy of the data is written in the read / write cache 9. The data in the read / write cache 9 is used to shorten the read time when the same data is present, but is also used to secure the data when the medium 2 is pulled out during the data read / write described later. . On the other hand, in the case of writing, the write data input from the interface unit 10 is written via the data control circuit 12, the disk controller 11 and the head controller 7. Even in this case, the read state is duplicated in the read / write cache 9 similar to the case of reading and the medium 2 is suddenly pulled out.

[0023] For the next medium 2 upon retrieval, it can not be at once withdraws the user will to pull out the mechanical resistance was Ke with the medium placing portion 19 in FIG. 3. Each center
When the sensor detects that the medium 2 is pulled, the medium placing portion 19 reaches the deepest position.
The disk controller 11 informs the data controller circuit 12 of the discard of the data within the time required to pull out the data from the first part to the frontmost part, and notifies the personal computer or the device connection main body of the discard of the data via the interface part 10. If the data is removed while it is in the write state, the friction or spring resistance of the mechanical portion of the medium mounting portion 19 is adjusted so that the write data in the read / write cache 9 is written and then removed.

If the data to be written within the time is the data in the read / write cache 9 in time, the data is written, and if it is not in time or there is a large amount, it is sent to the host computer 13 and the corresponding data is written. To erase.

When data is read out at the time of reading, if the data that has been read until just before the data is extracted fits in the read / write cache 9, the reading is continued, and if there is not enough data, the interface unit 10 is notified. Via the host computer 13.
After that, the writing to the host computer 13 is notified, and the failure of reading is notified.

It can be easily inferred that each of the above steps can be realized by software such as a program recorded in the recording medium 2.

Next, a second embodiment of the present invention will be described.
