BRIEF SUMMARY
SPECIFICATION
1. Technical Field
This invention relates to an electronic equipment, such as a tape recorder, a disc player or a radio receiver. More particularly, it relates to an electronic equipment having a cell container for containing a cell.
2. Background Art
In electronic equipments, such as tape-recorders, disc players or radio receivers, some are constructed for being fed with current from an external equipment, or exchanging information signals with the external equipments.
In these sorts of the electronic equipments, plug jacks are provided on an outer casing of the main body of the equipment, and a plug provided on one end of a connection cord drawn out of the external equipment is connected to this plug jack for establishing electrical connection with the external equipment.
On the other hand, some of the electronic equipments, such as tape-recorders, disc players or radio receivers, are designed so as to be portable.
With the portable electronic equipments, cells are used for a power source. Therefore, these electronic equipments are designed to fit the shape of the cell contained therein. The cell container designed to house a cylindrically-shaped cell has a cylindrically-shaped space for housing the cell. The cell container having such housing space occasionally has an opening in one end face of the cylindrically-shaped housing space for insertion and detachment of the cell via this opening. The cylindrically-shaped cell is inserted and removed with respect to such cell container with the longitudinal direction as the inserting/detachment direction.
The cell container has an opening/closure member for opening/closing the opening for preventing detachment of the cell housed therein. The opening/closure member has a terminal plate for establishing electrical connection between the cell housed within the cell container and an electronic circuit contained in the main portion of the electronic equipment. The opening/closure member is rotatably mounted via a pivot on the main portion of the equipment.
Meanwhile, the opening/closure member opening or closing the opening is sized to sufficiently cover the entire surface of the opening for positively holding the cell housed within the cell container and for preventing intrusion of dust and dirt into the main portion of the apparatus via the opening. In addition, the opening needs to be closed reliably.
On the inner lateral surface of the opening/closure member is mounted a terminal plate. This terminal plate is formed by a thin metal sheet and hence is deformed easily. If the terminal plate is deformed, it is contacted with an electrode of the cell different from the electrode with which the terminal plate is to be contacted thus shorting the cell. Thus the opening/closure member is sized to cover the terminal plate in its entirety for preventing an unneeded force from being applied to the terminal plate provided on the inner lateral surface thereof.
In addition, the pivot supporting the opening/closure member is provided outside of the opening. The reason is that, if the pivot is mounted facing the opening, the cell cannot be inserted or detached and if the pivot is mounted facing the outside of the main portion of the equipment, the equipment is impaired in appearance.
Thus the opening/closure member is sized to cover the entire surface of the opening and to cover the pivot mounted outside the opening.
If the opening/closure member is increased in size in this manner, the main portion of the equipment is also increased in size, making it impossible to reduce the overall size of the apparatus in its entirety.
DISCLOSURE OF THE INVENTION
An object of the present invention to reduce the size of the electronic equipment having a cell container.
Another object of the present invention is to provide an electronic equipment capable of reliably closing the cell container for preventing detachment of the cell contained therein.
Still another object of the present invention is to provide an electronic equipment in which the power source of the cell hous
