Description

[Detailed Description of the Invention] The present invention relates to a lid device for an article storage section that is most suitable for application to, for example, a lid device for a battery storage section in tape recorders, radio receivers, or other various electronic devices. It is something.

Conventionally, as a lid device for a battery storage part of the above-mentioned electronic equipment, the battery storage part provided in a cabinet is closed with a lid body that can be rotated around a fulcrum. Some devices have a structure in which a slidable lock button is engaged with the lid to lock the lid in the closed state.

In this type of lid device, when the battery is stored, a sponge etc. usually attached to the back of the lid body is pressed against the internal battery, and the lid body is always subjected to the above pressure reaction force in the closed state. Therefore, the moment the lock button is released, the lid is automatically pushed open by the pressing reaction force, which is convenient.

However, when the battery is not stored, the lid does not receive any of the above pressure reaction force, so even if the lock button is released, the lid will not open automatically, and in such cases, the lid will not open automatically. This is inconvenient because the user has to hook the lid and pull it open.

The present invention was devised in view of the above-mentioned circumstances, and the lid can be easily opened at the moment the lock button is released, regardless of whether or not there are batteries or other items stored in the storage compartment. The objective is to provide a lid device which can be opened automatically, and which has a simple structure with a small number of parts and assembly man-hours, and is low in cost.
