Description

[Detailed Description of the Invention] The present invention relates to a storage cartridge attachment/detachment structure, and in particular, it is designed to be able to operate without loading a storage cartridge, such as a personal radio, and to easily remove the storage cartridge once loaded. In recent years, personal radio has been approved as a means of communication that does not require radio operator qualifications. this is
Although it is a simple radio that uses the 900MHz band, new methods have been adopted to prevent the increase in the number of unlicensed and illegal stations, as was the case with citizen radio in the past. In other words, the main body of the radio is a ROM (Read Own Memory) issued through a prescribed procedure.
It is designed to not operate unless a cartridge is attached, and when transmitting, the call sign stored in the ROM cartridge is automatically transmitted, making it possible to immediately identify the source of the radio waves. .

Therefore, it goes without saying that once the ROM cartridge is installed, it should not be easily removed, but in the event of a malfunction of the ROM cartridge or a change in the license details, it is necessary to It is necessary that the person holding the device can easily remove it.

The present invention has been developed in view of the above-mentioned problems, and its purpose is to prevent the above-mentioned ROM cartridges and other storage cartridges from being easily removed, and to make it possible for manufacturers, etc., who have a legitimate reason for removing them, to The object of the present invention is to provide a structure for attaching and detaching a storage cartridge in a wireless device, which allows the storage cartridge to be easily removed.

Hereinafter, the configuration of the present invention will be explained based on FIGS. 1 to 5, which are examples thereof.

In the figure, 1 is a case of the main body of the radio, and 2 is a storage cartridge to be loaded into the case. 3 is an engaging portion provided on the cartridge 2; 4 is a case 1;
an engaging member provided inside the engaging portion 3;
It has an engaging part 5 which elastically engages and locks the engaging part 5, and the lock is released by pressing one side of the engaging part 5. In the illustrated example, the engaging members 4, 4 are adapted to rotate around a fulcrum 6, and the engaging portion 5 grips the memory cartridge 2 by means of a compression spring 7 whose one end is fixed to the case 1. is biased in the direction of Additionally, lock release arms 8, 8 are oppositely protruded from one side of the engaging members 4, 4, and by pressing them toward the storage cartridge 2, the engaging members 4, 4 are released. It rotates to release the lock. 9 shows the whole jig, and the striatal bodies 10,10 are attached to the striatal bodies 10,1.
A handle 11 is attached to make the handle 0 easier to handle, and the filament bodies 10, 10 are inserted through jig insertion holes 12, 12 provided in the case 1, and the arms 8, 8 are pressed with their tips. This makes it possible to release the lock. In the embodiment shown in FIG. 3, since a rigid wire such as a piano wire is used as the filament bodies 10,
There is no need for a guide etc. In the embodiment shown in FIG. 4, a linear guide groove 13 is integrally molded into the case 1. The guide groove 13 is appropriately bent, and a flexible wire or the like is used as the filament 10 inserted therein. In this embodiment, since the guide groove 13 is curved, it is extremely difficult to release the lock using wires or the like. The embodiment shown in FIG. 5 shows an example in which pipes 14, 14 are used as guides for the filament body 10, and the guide path from the jig insertion hole 12 to the arm 8 can be bent arbitrarily, and the It is impossible to release the lock.

According to the storage cartridge attachment/detachment structure for a radio device according to the present invention, it is possible to lock the storage cartridge to be loaded into the main body of the device, and the lock can be released using a jig having a striated body. Because of this structure, once the storage cartridge is installed, it cannot be easily removed, but it can only be removed using a special jig. Therefore, it is ideal as an attachment/detachment structure for storage cartridges that are prohibited to be removed without permission, such as storage cartridges in personal radios.
It can be prevented from being removed by the user. On the other hand, when it becomes necessary to remove the storage cartridge for maintenance inspection or for legitimate reasons, a person with proper authority can easily remove it using a special jig, and can take prompt action.
