Description

[Detailed description of the invention] Industrial application field This invention is used in electronic equipment such as wireless equipment, and is used in combination with a cartridge holding device for mounting a read-only memory (RCM) cartridge etc. in which information such as a unique number is written. The present invention relates to a cartridge extracting device used for.

1. Configuration of conventional example and its problems FIG. 1 shows an example of a wireless device in which additional functions are added as a cartridge. 5 is a housing of the wireless device as an electronic device, and 51 is an operation section. Power switch, volume adjuster, squelch adjuster,
An operation function is provided to control the operation of speakers and other wireless devices. Reference numeral 4 is a printed circuit board on which various electronic components are mounted, but since it has no relation to the present invention, a description thereof will be omitted. 1 is a cartridge holder; 2 is a cartridge that houses a part of the main functions of the wireless device as described above and can be attached to and removed from the cartridge holder; 52 is a lid 6 of the housing;
6 is a housing lid, 62 is a screw hole, and 63 is a set screw.

In the communication method that has become common when establishing a wireless station, some of the main functions, such as the number of the wireless station and some of the control functions, are written in a ROM and stored in the cartridge 2. It is designed to be installed in a predetermined location at a given time so that it can perform all functions, but when installing this cartridge, it is necessary to open the lid of the wireless device. On the other hand, since it is generally prohibited by the Radio Law for users to open the lid, it is inconvenient to send a staff member to install the cartridge, or to bring the device and have the staff install it. It was hot. For this reason, there has conventionally been a demand for a method of providing a predetermined function to a wireless device by inserting the cartridge into a holder without opening the lid, but there has been no suitable method that satisfies this demand.

Furthermore, it is desirable that a holder that satisfies such requirements be a simple jig for cartridge handling that is used only by the manufacturer or service personnel and is not provided to general users.

Purpose of the Invention It is an object of the present invention to meet the needs of the prior art and to provide a cartridge extraction device using an efficient extraction jig suitable for use by manufacturers or service personnel.

Structure of the invention In order to achieve the above object, the present invention releases the engagement between the cartridge and the holder by being inserted into the gap between the cartridge and its holder, and also releases the engagement between the cartridge and its holder. hold the part,
To provide an extraction device equipped with a jig as a special tool for extracting a cartridge together with the jig.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a diagram showing the casing structure of a wireless device to which the present invention is applied, where 5 is the casing of the wireless device, 51 is an operating section, 4 is a printed circuit board, 52 is a boss of a lid mounting screw, and 6 is a lid. , 62 is a screw hole for attaching the lid, and 63 is a mounting screw.Those with the same numbers as those in FIG. 1 are parts having the same function.
The lid 6 is attached to the screw boss 52 with a lid attachment screw 63 and shipped as a completed product. In this case, the shape of the head of the screw 64 or the shape of the groove in which the tool is inserted is made special, or a seal is pasted after the screw is tightened to prevent the lid from being opened by normal operations.

In this state, the insertion hole 61 of the cartridge 2 is fixed so that the recess 10 (described later) of the cartridge holder 1 is visible. The user receives the cartridge 2 along with a radio wave license and inserts it into the cartridge insertion slot 61, thereby adding the main functions of the wireless device or a part thereof and making the wireless device capable of operating organically. At this time, the cartridge 2 is fitted into the cartridge holder 1, and a general user cannot take out the cartridge 2.

3A and 3B are diagrams showing the structure of the cartridge holder 1 and the cartridge 2, in which 10 is a concave portion of the cartridge holder 1, 11 is a collar of the cartridge holder, and 12 is a locking claw that prevents the cartridge from being pulled out. 13 is a lock claw made of an elastic body; 14 is a lock release arm; 15 is a notch for movable the lock claw mechanism; 16 is a cutout for inserting the lock release finger of a special cartridge extraction jig; The introduction part of the claw of the jig for pulling out the cartridge, 18 is the connector A on the holder side that connects the cartridge 2 and the cartridge holder 1
It is. The main functions of the wireless device or a part thereof are housed inside the cartridge 2, for example, as a ROM, and the connector B23 and connector A18 on the cartridge side form a connection part, and the printed circuit board 4 of the wireless device and the ROM are electrically connected. connected to. 20 is a cartridge case, 21 is a cartridge case flange, and 22 is a cartridge case 2.
0 lock groove.

4A, B, and C are diagrams for explaining the operation of attaching or detaching the cartridge 2 to the cartridge holding portion 1, and are partially shown in cross section. When the cartridge case 20 is inserted into the recess 10 of the cartridge holding portion 1 from the state shown in FIG. 4A, the connector B23 is coupled to the connector A18. At this time, the edge 2 of the cartridge case 20
4 pushes the inclined surface of the lock pawl 13 and pushes the lock pawl mechanism 12 outward. Further, when the cartridge 2 is inserted, the lock pawl 13 falls into the lock groove 22, so that the cartridge 2 is held so that it cannot be pulled out. This state is shown in FIG. 4B. FIG. 4C is an external view of the cartridge 2 coupled to the cartridge holder 1. Therefore, the cartridge 2 is in a form in which only the top of the cartridge insertion opening 61 of the lid portion 6 is exposed, so that the cartridge 2 cannot be pulled out in this state. Furthermore, even if the lid 6 of the device were to be removed, it would be difficult to remove the cartridge 2.

FIG. 5 is a diagram showing the structure of the cartridge extraction jig 7 used in one embodiment of the present invention, and 71 is a lock release finger of the cartridge holder 1. This lock release finger 71 is divided into four parts by a notch 72 to avoid the base of the lock claw mechanism 12, and each part is divided into four parts.
The lock claw mechanism 12 is pressed outward by hitting the slope of the lock claw mechanism 12. 73 is a cartridge extraction claw tool, 7
4 is a peephole at the tip of the extraction claw 73. 75
is the tip of the finger 71, which is sloped so that the unlocking arm 14 can be smoothly unlocked. Next, the operation of the cartridge pull-out jig will be explained.

FIG. 6A shows a state in which the lock release finger 71 of the extraction jig 7 is inserted through the notch 16 of the cartridge holder 1 and the lock claw mechanism 12 is opened outward. 13 is removed from the lock groove 22. In this state, the tip of the pull-out claw 73 is in a shape that peeks out below the flange of the cartridge 2. This extraction jig 7 has extraction claws 7.
A stop portion 76 is provided so that the tip of the cartridge 3 fits under the collar of the cartridge 2. FIG. 6B shows the flange 2 of the cartridge 2 while pressing the extraction claw 73 with the pad of your finger.
1 and the cartridge 2 is pulled out. In this state, the lock claw mechanism 12 of the cartridge holder 1 is restored to its original state.

Effects of the Invention As explained above, the present invention has the advantage that once the cartridge is installed, it can only be removed using a special jig, and that the removal work can be done quickly using this jig.
