The present invention relates to an outer casing of an electronic device that is closed with a lid.

[Summary of the invention]

The present invention relates to an outer casing of an electronic device in which an opening provided for inserting a battery of a backup power source or the like is closed with a lid, in which a locking claw provided on the lid is inserted into the opening. A locked state in which the lock can be released by engaging with a part of the periphery of the opening, and a distal end of the elastic piece provided on the lid is brought into contact with a wall surface inside the casing near the periphery of the opening. By closing the opening with the lid in two types of locked states, including a locked state in which the lock cannot be released by using the lid, the lid and the outer casing can be made common. .

[Conventional technology]

-In electronic devices, even if they are of the same type, some require a backup power source and others do not, depending on the grade. For example, in video cameras, etc., there are high-end models that require built-in lithium batteries, etc. as backup power sources for the various memory functions and timer functions of electronic components built into the outer casing, and backup models that do not have the above-mentioned timer functions. There are lower models that do not require a power source. Therefore, conventionally, for the same model,
Two types of outer casings are created by preparing two types of lids, one that allows the battery compartment for bank-up to be opened and one that cannot be opened, or by changing the nesting of the battery housing part of the mold. Ta.

However, if two types of lids and outer casings were manufactured for the same model, not only would it be necessary to create separate molds, but the manufacturing process and parts management would become complicated, reducing productivity. will decrease.

In addition, the total mold cost, manufacturing cost, management cost, etc. increase, resulting in a cost problem.

[Problem to be solved by the invention]
