Abstract

PURPOSE:To prevent recording media from being erroneously taken out and data from being overwritten on them by providing a holding means for holding the recording media and a limiting means for limiting the movements of recording media held by the holding means. CONSTITUTION:When a memory card 1 is inserted to a card holder 2, the memory card 1 is sandwiched by card guide parts inside the holder 2 and elastically held. In this state, the card 1 can be freely loaded/unloaded. When that card 1 is a memory card to which write is inhibited, a switch 3 is slid in the direction of an arrow F so as not to erroneously use it, and the ejection of the card 1 is inhibited. Namely, the switch 3 is slid, and the card 1 can not be ejected. On the other hand, when canceling the lock, the switch 3 is reversely moved. Thus, the write inhibited card is prevented from being unexpectedly pulled out of the card holder.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium holder for accommodating a recording medium such as a memory card.

[0002]

2. Description of the Related Art Conventionally, a storage case for storing a recording medium such as a memory card has been a box-shaped case made of plastic or the like.

[0003]

However, in the above-mentioned conventional example, when carrying a recording medium for which writing is prohibited, the user may accidentally connect to the recording medium mounting device and perform writing. . Then, there is a problem that the data recorded in the recording medium is destroyed. In addition, dustproof and dripproof were also incomplete.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and in a recording medium holder, a holding means for holding a recording medium and a recording medium held by the holding means are provided. It is characterized in that a limiting means for limiting movement is provided.

Embodiments of the present invention will be described below with reference to the drawings.

<< Embodiment 1 >> FIG. 1 is a schematic view of a memory card holder according to Embodiment 1 of the present invention. As shown in FIG. 1, five memory cards 1 are inserted in the holder 2, and the switch 3 is for temporarily prohibiting the removal of the memory card 1.

Next, FIG. 2 is a detailed view showing how the memory card of FIG. 1 is locked. 2A shows a state when the card is inserted, in other words, a state in which the card can be removed, and FIG. 2C shows a state in which the card is locked and cannot be removed. Then, FIG. 2B shows a process in which the card is locked.

In FIG. 2, the memory card 1 is elastically held by the card guide portion 4 inside the holder 2. Further, a switch 3 is provided between the holder 2 and the card guide portion 4 so as to be slidable in the arrow A or B direction. The switch 3 is provided with an operating portion 3a for operating the switch 3 with a finger, and a hollow portion 3b is opened inside the switch 3. This cavity 3b
When the switch 3 moves from the state in which the convex portion 3c is fitted in the concave portion 4a to the state in which the convex portion 3c is fitted in the concave portion 4c, the convex portion 3c comes into contact with the guide portion 4b, and the arrow C direction It is provided to change the thickness of the switch 3 by denting. Further, the switch 3 is provided with an inclined portion 3d that comes into contact with the inclined portion 5a of the lock member 5 and moves the lock member 5 in the arrow D direction.

The lock member 5 is provided with a recess 5 that fits into a recess provided in the memory card 1 and prohibits removal of the memory card. Further, the lock member is attached in the direction of arrow E for unlocking. It is provided with a retaining portion 5b portion of the spring 6 for biasing.

Next, FIG. 3 shows a detailed view of the fitting of the holder and the memory card. In FIG. 3, the memory card 1 is inserted into the connector portion 7 provided with the holder 2, and the connector portion 8 provided with the memory card 1 and the connector portion 7 are provided.
The structure is such that the convex portion 9a of the elastic portion 9 provided inside is engaged.

Next, the actual usage of the holder 2 will be described with reference to FIGS. When the memory card 1 is inserted into the card holder 2, the memory card 1 is elastically held by being sandwiched by the card guide portion 4 in the holder 2. In this state, the card 1 can be freely attached and detached as shown in FIG.
If the card 1 is a write-protected memory card, the switch 3 is slid in the direction of arrow F in FIG. That is, in FIG. 2, the switch 3 slides in the direction of arrow A, and the lock member 5 is pressed and moved in the direction of arrow D. Then, the operating portion 3a of the switch 3 comes into contact with the end portion 2b of the holder 2, and the convex portion 3a of the switch 3 fits into the concave portion 4c of the card guide portion 4, so that the card 1
Cannot be taken out. To unlock the lock, the switch 3 may be moved in the direction of arrow B.

With the above-mentioned structure, it is possible to prevent the memory card for which writing is prohibited from being accidentally removed from the card holder, and to prevent accidental overwriting. Moreover, since the contact portion of the memory card is completely sealed, a high dustproof effect and a high dripproof effect can be obtained, and the memory card can be reliably protected.

<Embodiment 2> This embodiment 2 is the same as the embodiment 1 described above.
2, the elastic holding member 21 is provided in the lower portion of the lock member shown in FIG. 4, and the holding member 21 presses the memory card 1 to prohibit the removal of the memory card 1.

<< Embodiment 3 >> FIG. 5 is a schematic view of a memory card holder according to Embodiment 2 of the present invention. As shown in FIG. 5, six memory cards 11 are inserted in the holder 12, and the switch 13 is for temporarily prohibiting the removal of the memory cards 11.

FIG. 6 shows a detailed view of fitting the holder and the memory card. In FIG. 6, the connector portion 13 provided in the holder 12 and the connector portion 14 provided inside the memory card 11 are engaged with each other. Here, the connector unit 13 outputs information such as the type of the memory card 11, writing / reading speed, writing / reading voltage, and whether writing is possible.
Can read the information.
Further, the connector section 14 has a polishing section 14a, and the connector section 13 is cleaned every time the memory card is attached or detached.

Next, the actual usage of the holder 12 will be described with reference to FIGS. 7 and 8. When the memory card 11 is inserted into the holder 12, the connector 13 on the holder 12 side and the connector portion 14 on the memory card 11 side contact each other, and the controller 15 determines whether the memory card 11 is writable. When it is detected that writing is prohibited, the plunger 16 is set to the memory card 1
The cutout portion 11a of No. 1 is fitted. In this state, it is impossible to remove the memory card 11 from the holder 12. To release this lock, the release switch 17 provided on the holder is pressed to release the lock, and the memory card can be taken out.

With the above configuration, even when a write-protected card and a writable card are mixed and carried, the write-protected card is automatically detected and the card is removed. Since it is prohibited, it is possible to prevent accidental use of a write-protected card. In addition, since the connector is cleaned every time the memory card is attached or detached, good electricity can always be supplied. In addition, it is possible to ensure dustproof and dripproof when carrying.

[0018]

As described above, since the recording medium holder is structured to have the holding means for holding the recording medium and the limiting means for limiting the movement of the recording medium held by the holding means, the writing is performed. It is possible to prevent the recording medium from being accidentally taken out and overwritten when the recording medium for which the prohibition is prohibited is held in a mobile phone. Furthermore, it becomes possible to obtain a reliable dustproof and dripproof effect.
