Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an electronic device equipped with a data card that stores various data.

[Prior art]

In recent years, in relatively compact portable electronic devices, a data card equipped with a memory that has a terminal that is electrically connected to the device is removably stored in a storage section within the device body, thereby increasing the memory capacity. Increasing capacity or exchanging various data, etc.
We are working to increase its functionality.

When inserting such a data card into an electronic device, it is necessary to turn off the power so that the memory of the data card will not be destroyed when replacing it.If you replace the data card without turning off the power, the memory etc. will be destroyed. This may cause electronic equipment to malfunction.

For this reason, conventional electronic devices are equipped with a lock switch in addition to a power switch, and operating the lock switch when replacing a data card turns the power on and off, and also locks the knob that secures the lid to the storage compartment. It is now also possible to cancel the contract.

[Problems with conventional technology]

The data card insertion/removal method described above can reliably prevent memory damage when replacing the data card, but when replacing the data card, turn off the power switch and then operate the lock switch to remove the knob. You will not be able to remove the lid and remove the data card from the storage compartment unless you release the lock and operate this knob to release the lid. After placing the lid in the storage compartment with the knob pulled, the lid is fixed by operating the knob, and then the knob is locked by operating the lock switch.
The power switch must be turned on. For this reason, the task of exchanging data cards is complicated, cannot be easily exchanged, and is extremely troublesome.

[Purpose of invention]
