Description

[Detailed description of the invention] [Technical field of the invention] This invention relates to a memory pack.

[Technical background of the invention and its problems]

A small electronic device that is loaded with a memory pack and used to input a word in one country's language (e.g. Japanese) and translate it into a word with the same meaning in another different country's language (e.g. English). There is a small electronic translator. With this small electronic translator,
Translation is performed by loading a word memory pack that stores word information of the language to be translated into the main body of the device, and by exchanging this memory pack, the language of the country to be translated can be changed.

Memory packs used in small electronic devices such as the above-mentioned small electronic translators have a storage element, such as a large-scale integrated circuit chip, built-in inside the case.
A plurality of terminal electrodes connected to each electrode of the memory element are exposed outside the case, and each terminal electrode is formed on the outer surface of the case, or inside the case through an opening provided in the case. It is installed so that it is exposed outside the case.

On the other hand, a small electronic device that is used with a memory pack loaded therein is provided with a memory pack storage section, and within this memory pack storage section, a plurality of memories are stored in correspondence with each terminal electrode of the memory pack. A terminal electrode for pack connection is provided.

The memory pack is stored in a memory pack storage part of a small electronic device and loaded into the small electronic device. When the memory pack is stored in the memory pack storage part, each terminal electrode of the memory pack contacts an elastic contact piece. It is electrically connected to each electrode terminal in the memory pack storage section through the memory pack storage section. Generally, a leaf spring is used as the elastic contact piece, and the elastic contact piece made of the leaf spring is attached to each terminal electrode in the memory pack housing or on each terminal electrode of the memory pack. .
In addition, the memory pack stored in the memory pack storage section is held down by the back cover of a small electronic device.
Each terminal electrode of the memory pack is fixed in contact with each terminal electrode in the memory pack storage portion through an elastic contact piece.

However, with conventional memory packs that are held and fixed in the memory pack storage by the back cover of a small electronic device as described above, it is necessary to use your fingers to secure the memory pack stored in the memory pack storage. This operation is cumbersome as you have to attach the back cover while pressing it in. Also, if you accidentally remove the back cover while using a small electronic device, the memory pack will lift up and the terminal electrodes will be damaged by the memory. Since the terminal electrodes are separated from the terminal electrodes in the pack storage section, there is a problem in that this causes malfunctions in the operation of small electronic devices.

[Purpose of invention]

This idea was created in view of the above-mentioned circumstances, and its purpose is to make it easier to attach the back cover of a small electronic device when it is stored in the memory pack storage area. In addition, even if the back cover of the small electronic device is accidentally removed while the small electronic device is in use, the terminal electrodes will not be separated from the terminal electrodes in the memory pack housing, thereby preventing malfunctions of the small electronic device. Our goal is to provide a memory pack that allows you to

[Summary of the idea]

That is, this invention movably provides a pack fixing member that removably engages with a locking part provided in a memory pack storage section of a small electronic device on the outside of the memory pack case. According to the above, since the memory pack stored in the memory pack storage section of a small electronic device can be fixed to the memory pack storage section using the pack fixing member, the memory pack can be fixed to the memory pack storage section when attaching the back cover to the small electronic device. There is no need to suppress
In addition, even if you remove the back cover, the memory pack will not lift up unless you remove the pack fixing member from its locking part, so even if you accidentally remove the back cover while using a small electronic device, the memory pack will not come up. The terminal electrodes will not separate from the terminal electrodes of the memory pack storage section and will not cause abnormal operation of the small electronic device.

[Example of idea]

Hereinafter, one embodiment of this invention will be described with reference to the drawings, taking as an example a word memory pack used in a small electronic translator.

Further, 12 is a pressure cord coil spring fitted into a through hole 11 formed in the resin frame 1, and by electrically connecting the upper surface panel 4 and the lower surface panel 7 with this coil spring 12, A memory element and a circuit board arranged within the resin frame 1 are provided with electrostatic shielding.

In this way, case A includes resin frame 1 and
This case A is composed of an upper panel 4 and a lower panel 7. Since the upper and lower surfaces of the case A are composed of the upper panel 4 and the lower panel 7 made of metal plates, the entire case is made of synthetic resin. Unlike conventional cases, there is no need to increase the wall thickness to increase mechanical strength, and
The thickness (height) of the resin frame 1 only needs to be large enough to accommodate the memory element and the circuit board, so the overall thickness of the case A is much thinner than conventional resin cases.

On the other hand, inside the case A, there are housed a circuit board 13 on which a circuit pattern is formed, and memory elements 14, 14 made up of large-scale integrated circuit chips that store word information in the language of a predetermined country. These memory elements 14, 14 are connected to the circuit pattern on the circuit board 13 by connecting their respective lead terminals 15... to the circuit pattern on the circuit board 13.
In addition, each electrode (lead terminal 15...) of the memory elements 14, 14 is connected to the portion of the circuit board 13 facing the terminal hole 5 on the upper surface of the case A via a circuit pattern. A plurality of connected terminal electrodes 16 are arranged in an array.

Reference numeral 17 denotes an interconnector superimposed on the terminal electrode array portion of the circuit board 13. As is well known, the interconnector 17 is made by alternately laminating insulating rubber and conductive rubber, and is held between a pair of connector holders 18, 18. This interconnector 17 is
The connector is penetrated through the terminal holes 2 and 5 formed in the resin frame 1 and the upper panel 4 of the case A, and the lower surface of the connector is brought into contact with the terminal electrodes 16 on the circuit board 13, and the upper part of the connector is projected to the outside of the case A. It is held in the terminal holes 2 and 5 in this state.

Note that the circuit board 13 is fixed to the resin frame 1 with screws 10, 10.

Further, 19 is a pack fixing plate provided on the outside of the case A. This pack fixing plate 19 is made of a metal plate, and both side edges thereof are bent upward. Locking claws 20, 20 and elongated holes 21, 21 are formed in the rising walls 19a, 19a on both sides, respectively, and a positioning claw 22 is formed in the center of one end of the pack fixing plate 19. . Incidentally, long holes 23, 23 are formed in the pack fixing plate 19 to provide relief for the screws 10, 10. This pack fixing plate 19 is arranged to overlap the lower surface of the lower panel 7 of the case A, and is placed on the rising walls 19a, 19a on both sides.
It is fitted into the case A so as to hold the resin frame 1 from both sides. Moreover, this pack fixing plate 19 has elongated holes 2 in its rising walls 19a, 19a.
By inserting stoppers 3, 3 formed on both sides of the resin frame 1 into the holes 1, 21, the case is supported by the stoppers 3, 3, and the case is held until the ends of the elongated holes 21, 21 touch the stoppers 3. It is provided so as to be slidable in the longitudinal direction.

The memory pack thus constructed is loaded into a small electronic translator B as shown in FIG. To explain the configuration of this small electronic translator, in FIG. 5, 24 is the main body case of the translator, 25 is a back cover made of a metal plate combined with the main body case 24, and 26 is provided inside the main body case 24. A circuit board 27 is a board holder made of synthetic resin that is provided inside the main body case 24 and superimposed on the lower side of the circuit board 26. A rectangular memory pack storage part 28 is formed vertically through the board holder 27 in accordance with the external shape of the memory pack case, and a pack fixing plate 19 is formed on both sides of the memory pack storage part 28. Walls 19a, 19a and locking claw 2
Recesses 29, 29 into which 0, 20 are movably inserted
are formed respectively, and on one end side of these recesses 29, 29, locking claws 20, 2 of the pack fixing plate 19 are formed.
Groove-shaped locking portions 30, 30 for locking 0 are formed, respectively. Further, in the center of one end of the memory pack housing section 28, an alignment recess 31 is formed into which the alignment claw 22 of the memory pack fixing plate 19 is inserted. Further, on the inner bottom surface of the pack storage portion 28, that is, on the lower surface of the circuit board 26, a plurality of memory pack connection terminal electrodes 32 are arranged in correspondence with each terminal electrode 16 of the memory pack.

To explain how to load the memory pack into the above-mentioned small electronic translator B, when loading the memory pack into the translator B, first load the memory pack from the back cover 2 of the translator B.
5 to open the memory pack storage section 28, and then the memory pack is fitted into the memory pack storage section 28 and stored. After storing the memory pack in the memory pack storage part 28 in this way, slide the pack fixing plate 19 while pressing the memory pack case A against the inner bottom surface of the memory pack storage part 28 to lock the memory pack storage part. The locking pawls 20, 20 and the positioning pawl 22 of the pack fixing plate 19 are inserted into and engaged with the portions 30, 30 and the positioning recess 31. In this case, if you accidentally store the memory pack with the right and left sides reversed, the locking claws 20, 20 and the alignment claws 22 will hit the inner wall of the memory pack storage section 28, making it impossible to move the pack fixing plate 19 any further. This prevents the memory pack from being inserted backwards.

As described above, the locking claw 2 of the pack fixing plate 19 is
0,20 at the locking part 3 of the memory pack storage part 28.
0, 30, the memory pack will cause its terminal electrodes 16 to connect to the interconnector 17 thereon.
The pack fixing plate 19 is in contact with the terminal electrodes 32 in the memory pack housing 28 through the
Fixed by After this, all you have to do is attach the back cover 25 to the translator B again and cover the memory pack storage section 28.The attachment of the back cover 25 can be done easily without having to press down on the memory pack as in the conventional case. can be done. Note that the back cover 25 is formed with protrusions 33, 33 that protrude from the inner surface thereof. These protrusions 33, 33 are in contact with the rear edge of the pack fixing plate 19, so that the pack fixing plate 1
If these protrusions 33, 33 are provided on the back cover 25, the pack fixing plate 19 will shift due to vibration, etc., and the locking claws 20, 9 will be prevented from moving toward the rear edge.
20 can be prevented from coming off from the locking parts 30, 30.

That is, the memory pack is provided with a pack fixing plate 19 on the outside of its case A, which engages with the locking parts 30, 30 provided in the memory pack storage section 28 of the small electronic translator B. , the memory pack stored in the memory pack storage section 28 can be fixed by the pack fixing plate 19, and therefore there is no need to hold and fix the memory pack with the back cover 25 of the translator.
Since there is no need to press down the memory pack when attaching the back cover 25, the back cover 25 can be attached easily.

Furthermore, the memory pack is fixed to the memory pack storage section 28 by the pack fixing plate 19 provided on the memory pack, not by the back cover 25 of the translator B. Even if the back cover 25 is removed, the memory pack will not lift up unless the pack fixing plate 19 is released from its locking parts 30, 30.
Even if you accidentally remove the back cover 25 while using the translator, the terminal electrodes 16 of the memory pack will not separate from the terminal electrodes 32 of the memory pack housing, which will prevent malfunctions in the translator's operation. .

Further, when taking out the memory pack from translator B, after removing the back cover 25, move the pack fixing plate 19 to release it from the locking parts 30, 30, and then take out the memory pack.

In the above embodiment, the pack fixing plate 19 that holds the memory pack from the bottom side is used as the pack fixing member, but this pack fixing member is movably provided outside the memory pack case and is attached to the memory pack storage section. Any type of material may be used as long as it can be releasably engaged with the stop portion.

Furthermore, although the above embodiment describes a memory pack used in a small electronic translator, this invention can also be applied to small electronic devices other than small electronic translators. The type may be ROM (read only memory), RAM (random access memory), or ROM/RAM.

[Effect of idea]

This idea is based on the outside of the memory pack case.
A pack fixing member is provided that removably engages with a locking part provided in a memory pack storage part of a small electronic device, and the memory pack is fixed to the memory pack storage part by this pack fixing member. Therefore, when the memory pack is stored in the memory pack storage section of a small electronic device, the back cover of the small electronic device can be easily attached without pressing the memory pack, and the operation of the small electronic device can be easily attached. Even if you accidentally remove the back cover before the memory pack is finished, the memory pack will not lift up, and its terminal electrodes will separate from the terminal electrodes in the memory pack storage area, causing malfunctions in the small electronic device. I won't let you.
