[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a processing device of an information storage device used for sharing data between devices in electronic devices such as information processing, and more particularly to a write prohibiting mechanism for the purpose of protecting internal data of an external storage device. is there.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in an information processing device, as a method for sharing data between devices, an external storage device that can be attached and detached and can freely write data is generally used. This type of external storage device is usually provided with a write inhibit mechanism for the purpose of protecting internal data so that valuable storage data is not accidentally erased.
[0003]
A typical example of a write-protection mechanism is to change the shape of a part of the housing of an external storage device, such as that found on magnetic tapes and floppy disks, and to change the shape of the information processing device optically or mechanically. The detection method is known.
[0004]
FIG. 5 shows an example of a conventional write prohibiting mechanism using a 3.5-inch floppy disk as an example.
[0005]
The floppy disk 1 is affixed with a label for writing a label for writing a slide shutter 2 for writing or reading data, a bearing unit 3 for rotating a built-in magnetic disk, a title, etc. A portion 4 and a write protect tab 5 are provided. As shown in FIGS. 2A and 2B, the write protect tab 5 includes a slide-type notch 5a that can be freely opened and closed, and an opening window 5b whose opening and closing state is changed by the movement of the notch 5a. .
[0006]
That is, the write prohibiting mechanism using the write protect tab 5 detects two forms of shape change according to the position of the notch 5a, that is, the open / closed state of the opening window 5b by using a contact switch or the like. The device side identifies whether writing is permitted or prohibited.
[0007]
As another method for prohibiting data writing, there is a method of blocking the electrical writing path by setting a microswitch, for example, like a memory card that electrically writes data.
[0008]
Any of these types of write-inhibiting mechanisms mechanically creates a change in physical shape, and thus has an advantage that a human can recognize at a glance whether the writing is permitted or prohibited.
[0009]
However, in any case, the external storage device requires a certain size and thickness.
[0010]
On the other hand, there is also a method of storing the write prohibition state as internal data of the external storage device. This method has an advantage that it can be adopted in any external storage device regardless of the size and thickness of the external storage device.
[0011]
However, there is a problem in that it is not possible to recognize whether writing is permitted or prohibited until an external storage device is mounted on an information processing device and actually operated.
[0012]
[Problems to be solved by the invention]
As described above, conventionally, there has been a problem that a certain size and thickness are required as an external storage device in order to allow a human to recognize that the writing is prohibited.
[0013]
Therefore, the present invention enables a human to recognize at a glance that the information storage device is in a write-inhibited state even if the information storage device is small and thin, and the write-inhibit mechanism is inexpensive. An object of the present invention is to provide an information processing apparatus that can be realized.
[0014]

[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0019]
FIG. 1 schematically shows a configuration of a memory module according to the present invention. 1A is a plan view of the memory module, and FIG. 1B is a cross-sectional view taken along the line AA.
[0020]
This memory module 11 is used as an external storage device such as a floppy disk. For example, a plastic small card type support 12 and a semiconductor memory package as a storage medium (details will be described later). 13 is built-in.
[0021]
The support 12 has a label affixing portion 14 for affixing a display label for entering an outline of internal data stored in the semiconductor memory package 13, and inadvertent data for the semiconductor memory package 13. A seal sticking portion 15 for sticking a conductive seal as a state indicating member for prohibiting writing is provided.
[0022]
The support 12 has a size of, for example, 37 mm × 45 mm (less than half the size specified by ISO7813) and a thickness of 0.76 mm ± 0.08 mm specified by ISO7813.
[0023]
In the present embodiment, the memory module 11 is formed with a size of half or less of the area defined by ISO7813 so that it can be used like a floppy disk.
[0024]
Also, one corner of the support 12, for example, one corner facing the direction of insertion into the drive device is cut obliquely to function as a reverse insertion prevention.
[0025]
In addition to this reverse insertion prevention function, it is possible to use the memory module 11 in a manner that restricts the use of the memory module 11 depending on the presence or absence of a cut portion. For example, in the case where the semiconductor memory package 13 operates at a voltage of 5V and a semiconductor memory package 13 operates at a voltage of 3.3V, a cut portion is provided only at a voltage of 5V. Can be prevented from being mounted on the drive device, and the internal memory chip can be protected from electrical damage due to a difference in power supply voltage.
[0026]
The label sticking portion 14 is formed of a concave portion corresponding to the thickness of the label to be stuck, and is formed from the front surface to the back surface so as to cover one side of the support 12.
[0027]
The seal sticking portion 15 is formed of a circular concave portion having a diameter of 10 mm, for example. This sticking part 15 indicates the sticking position of the conductive seal, escapes the thickness of the conductive seal, and ensures the flatness of the surface of the memory module 11 so that it can be hooked when inserting / removing the drive device. The seal is prevented from being peeled off or the surface thereof being shaved.
[0028]
The conductive seal functions as a light protector for realizing a write prohibition mechanism. For example, the conductive seal is an inexpensive structure formed by coating a non-adhesive surface of an adhesive paper surface with a conductive material such as aluminum. . The conductive seal is formed in a circular shape having a diameter of 8 mm, for example, so that the conductive seal can be attached in the seal attaching portion 15 on the support 12.
[0029]
That is, the conductive seal is attached to the seal attaching portion 15 on the support 12 so as to visually appeal that data writing of the memory module 11 to the semiconductor memory package 13 is prohibited. Can be done.
[0030]
Further, the write prohibition mechanism can be easily realized by automatically identifying that data writing is prohibited from the conductive state created by the conductive seal.
[0031]
FIG. 2 shows a schematic configuration of the semiconductor memory package 13. 2A is a perspective view showing the sealing surface side of the package 13, FIG. 2B is a perspective view showing the terminal surface side, and FIG. 2C is a cross-sectional view taken along the line BB. It is.
[0032]
In the semiconductor memory package 13, for example, a 16M bit NAND flash EEPROM chip 13b which is a nonvolatile semiconductor memory device is mounted on a resin substrate 13a. It is connected to the wiring on the substrate 13a. The periphery of the chip 13b including this connecting portion is sealed with a sealing resin 13d by a single-side transfer molding method.
[0033]
Further, the wiring on the resin substrate 13a is exposed from the non-resin sealing surface side through a through hole, and is drawn out as a flat type external connection terminal 13e.
[0034]
In the present embodiment, the size of the semiconductor memory package 13 on the terminal surface side is set to 16.62 mm × 27.59 mm, and the size of the semiconductor memory package 13 is less than half of the area of the support 12 in the longitudinal direction. Yes.
[0035]
And the upper surface of the external connection terminal 13e is attached so as to be substantially the same as the surface of the support 12 on which the sticking part 15 or the like is formed.
[0036]
In the memory module 11 having the above-described configuration, a drive device such as a floppy disk drive is required when used as an external storage device such as a floppy disk.
[0037]
FIG. 3 shows an example where the memory module 11 is mounted and used in a mounting portion of the electronic device using a drive device prepared separately from the electronic device such as information processing.
[0038]
For example, when using it like a floppy disk, the memory module 11 is once taken into the card-shaped holder 21 and the card-shaped holder 21 is mounted in the mounting portion of the electronic device.
[0039]
The card-like holder 21 has a predetermined size (for example, type II) defined by, for example, PCMCIA (the Personal Computer Memory Card International Association), has an input / output interface, and performs data writing and reading. For example, a memory controller (not shown) as a drive device is built in.
[0040]
FIG. 4 schematically shows a main part of the configuration of the card-shaped holder 21.
[0041]
That is, the connector pin holder portion 23 is provided in the connector portion 22 of the card-like holder 21 to which the memory module 11 is mounted. The connector pin holder portion 23 includes a plurality of connector pins 24 that are in contact with the external connection terminals 13 e of the semiconductor memory package 13 and a connector that is in contact with the seal pasting portion 15 on the support 12. Pins 25 and the like are provided.
[0042]
The connector pins 24 are respectively connected to the memory controller built in the card-like holder 21.
[0043]
For example, at least two connector pins 25 are provided in a direction orthogonal to the plane of the drawing, and are spaced apart from each other by 1 mm or more. This connector pin 25 is an identification circuit (not shown) provided in the electronic device or the card-like holder 21 for identifying permission or prohibition of data writing by mutual conduction or non-conduction of the pins 25. It is connected to the.
[0044]
For example, when the conductive seal 16 is not affixed on the memory module 11, the connector pin 25 is in direct contact with a part of the support 12 (the seal affixing portion 15) that does not have conductivity. In this case, since the support 12 is not conductive, the connector pins 25 are in a non-conductive state, and the write permission state is identified by the identification circuit.
[0045]
On the other hand, for example, when the conductive seal 16 is affixed on the memory module 11, the connector pin 25 is brought into contact with the conductive seal 16. In this case, since the conductive seal 16 is conductive, the connector pins 25 are connected to each other through the conductive seal 16 so that the write-inhibited state is identified by the identification circuit.
[0046]
As described above, the memory module 11 is in a write-inhibited state by attaching the conductive seal 16 to the seal attaching portion 15 on the support 12. By attaching the conductive seal 16, the user recognizes that the memory module 11 is write-protected, and the connector pins 25 are connected to each other as the memory module 11 is attached to the card-like holder 21. The memory controller is identified that the memory module 11 is in a write-protected state due to the conductive state.
[0047]
As described above, the write-inhibited state can be automatically identified by the change in the electrical state, and the write-inhibited state can be easily recognized visually.
[0048]
That is, when the memory module is in a write-protected state, the conductive seal is pasted at a predetermined position. This makes it possible to visually detect that the memory module is in a write-protected state and to detect it electrically. For this reason, it is possible to sufficiently cope with a small and thin memory module as compared with a method of creating a write-inhibited state using a shape change state. Therefore, even if the memory module is small and thin, a human can recognize at a glance that the memory module is in a write-protected state.
[0049]
In addition, in this method, that is, a method of creating a write-protected state by attaching a conductive seal, the memory module can be easily reproduced (returning from the write-protected state to a writable state) by removing the seal. Is possible. For example, as compared with a method using a hole or the like, the reproducibility is excellent and there is no concern that the rigidity of the memory module is reduced.
[0050]
Moreover, according to this method for identifying whether or not data writing is prohibited by the presence or absence of the conductive seal, the write prohibition mechanism is compared with the method of creating the write prohibition state using the state of the shape change. Can be realized at low cost.
[0051]
In the above embodiment, the case where a write-protected state is created by applying a conductive seal to a non-conductive memory module has been described. However, the present invention is not limited to this. For example, a conductive seal is applied. By doing so, it is possible to create a write permission state.
[0052]
That is, in the case of this method, the state of conduction by applying the conductive seal can be made to correspond to a state in which writing is prohibited and to a state in which writing is possible.
[0053]
For example, when writing is prohibited by applying a conductive seal, there is a risk that necessary data may be erased when contact failure with a connector pin occurs for some reason.
[0054]
On the other hand, when writing is permitted by applying a conductive seal, it is necessary to apply a seal in advance. Further, in this case, it is necessary to sufficiently ensure the reliability of detection of the conduction state including the wear of the seal against the mounting in the overwhelmingly writable state.
[0055]
As described above, in the above-described embodiment, from the aspect of ensuring the reliability of detection of the conductive state, the conductive state by attaching the conductive seal is associated with the writing prohibition state, which is overwhelmingly less in number of mountings. However, it is possible to appropriately select whether the continuity state corresponds to the write prohibition state or the permission state according to the user and the purpose of use. Yes.
[0056]
Further, in the case of a memory module having electrical conductivity, it is possible to arbitrarily create a write prohibited state or a write permitted state by applying a non-conductive seal.
[0057]
Further, the memory module is not limited to be configured to be used by being mounted on an electronic device together with the card-shaped holder, but is configured to be used by directly mounting the memory module on a mounting portion of an electronic device including a drive device. It is also possible.
[0058]
Further, the present invention can be applied not only to the memory module but also to various storage media such as a floppy disk and a magnetic tape.
[0059]
Furthermore, not only the seal but also the effect similar to the above-described embodiment can be expected by applying a paint such as conductive ink or non-conductive ink.
[0060]
Of course, various modifications can be made without departing from the scope of the present invention.
[0061]
【The invention's effect】
As described above in detail, according to the present invention, even if the information storage device is small and thin, a human can recognize at a glance that writing is prohibited, and writing can be performed. An information processing apparatus capable of realizing the prohibition mechanism at a low cost can be provided.
