Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a portable radio receiver,
The present invention relates to a lid opening / closing mechanism that is suitable for use in small electronic devices such as tape recorders and disk players.

[0002]

2. Description of the Related Art For example, batteries are used as a power source in small electronic devices such as portable radio receivers, tape recorders and disk players. For this reason, the housing is provided with a cylindrical battery housing portion into which a predetermined number of batteries are loaded, and is normally closed by a battery lid that is assembled to form a part of the main surface of the housing. There is. Various structures have been conventionally adopted for this battery lid. For example, the battery housing has a substantially semi-cylindrical shape, and an elongated battery lid with an arcuate cross section is attached to the open side surface in the longitudinal direction. There is also.

Further, in the battery housing portion which is constructed by opening one side surface portion in the longitudinal direction, a minus side terminal formed by an elastic member such as a coil spring or a leaf spring is arranged on the closed bottom side. At the same time, a positive terminal is attached to the battery lid arranged on the opening side. Therefore, the battery lid has a terminal plate function as well as a lid function of pressing the battery loaded in the battery housing portion to the negative terminal side. Regarding the opening / closing mechanism of such a battery lid, a rotating structure rotatably supported by a supporting portion provided in an opening portion of the battery housing portion of the housing, and a guide portion formed along the opening portion of the battery housing portion. There is known a slide structure or the like that is slid by being assembled to the.

As described above, since the battery cover has a terminal plate function as well as a cover function, it is preferable that the battery cover has a structure that does not easily come off from the housing, especially in portable equipment. It is necessary to have a structure in which the battery can be easily replaced and the battery can be easily replaced. Moreover, in a portable device, it is essential that the device is small and robust as a whole, and the opening / closing mechanism of the battery lid must also realize this condition.

[0005]

In the above-mentioned slide type battery lid opening / closing mechanism, the battery lid can be opened / closed by a simple operation of sliding along the housing, and at the time of opening operation. Since there is no particular problem even if it protrudes from the housing, it is possible to form it in a relatively large size.
On the other hand, this slide-type battery lid opening / closing mechanism requires some kind of stopper mechanism so that the battery lid does not drop out of the housing in the opened state. In addition, since the battery loaded in the battery housing is in a state of being pressed against the battery lid side by the negative side terminal, if the battery lid is accidentally slid in the opening direction, the battery pops out. There was a point.

On the other hand, in the rotating type battery lid opening / closing mechanism, since the battery lid is originally rotatably supported by the supporting portion formed in the housing, the battery housing portion is opened. No mechanism is required to prevent it from falling out of the housing in this state. However, this rotating type battery lid opening / closing mechanism needs to be provided with a stopper mechanism that holds the battery housing in a closed state. Also, this battery lid has
Since the stopper mechanism and the rotation fulcrum portion are disposed on both sides facing each other, it is necessary to provide the stopper mechanism and the rotation fulcrum portion at the outer position with respect to the opening of the battery storage portion. Therefore, the battery lid becomes larger than the outer dimensions of the battery, which causes a problem in downsizing of the device. In addition, opening and closing this battery lid
There is a problem that the operation is troublesome because it requires two operations, a lock operation and a rotating operation.

Therefore, the present invention provides a portable device which is easy to open and close, and is capable of preventing the battery lid from coming off from the housing even in an opened state, and having a simple structure to achieve downsizing of the device body. It is proposed for the purpose of providing a suitable lid opening / closing mechanism for use in a battery lid or the like.

[0008]

A lid opening / closing mechanism according to the present invention which achieves this object is a lid rotatably assembled to a housing so as to open and close a storage portion in which an object is stored. In the body opening / closing mechanism, a fulcrum portion is provided on one end side of the lid body, and the fulcrum portion is rotatably supported by a support portion provided in the housing located at an opening portion of the storage portion. It is composed of a rotating member and a lid member which forms a part of the main surface of the housing when the opening is closed by being formed in an outer shape corresponding to the shape of the opening of the storage section.
The lid member is slidably combined with the rotating member in a state where the rotating member is prevented from falling off, and one end portion of the rotating member facing the fulcrum portion is relatively engaged with the opening portion of the storage portion. A locking means is provided and configured.

Further, in the lid opening / closing mechanism according to the present invention, the rotating member formed of a metal plate is used to load the battery, and the storage portion configured as the battery storage portion is closed. It is configured as a terminal member with which the terminal portion of is in contact.

Further, the battery accommodating portion is provided with a connecting terminal plate connected to the rotating member configured as the terminal member. The connecting terminal plate is formed of a leaf spring material and the lid body serves as the accommodating portion. In the closed state, the rotation member is brought into contact with the inner surface of the rotation member in a state of being elastically displaced, thereby imparting the rotation member with a rotation habit in the direction of opening the storage portion.

[0011]

According to the lid opening / closing mechanism of the present invention, the turning operation of the turning member can be performed with respect to the housing by slidingly operating the lid member with respect to the turning member. The closed storage part is opened. Therefore, for example, it is possible to easily perform the operation of taking out and loading the battery from the storage portion that constitutes the battery storage portion in which the battery is stored as the storage object. Further, since the lid member is slidably operated with respect to the rotating member to rotate integrally with the rotating member at the position where the locking state with the housing is released, the rotating fulcrum portion is located inside. Will be done. Therefore, the battery lid
The size can be made substantially the same as the outer diameter of the battery, and the size of the device can be reduced.

The storage portion is configured as a battery storage portion for storing a battery, and the rotating member acts as a terminal member with which the terminal portion of the battery stored in the battery storage portion comes into contact, so that the battery storage portion is closed. Since the lid member provided with the retaining means for holding constitutes a part of the housing, the overall structure has a small number of parts. Further, since the connection terminal plate acts as a member that imparts a turning habit to the rotating member to open the battery storage portion, members such as a coil spring are also unnecessary.

The lid member 26 is formed of a synthetic resin material of the same quality as that of the receiver main body 2 into an outer shape having substantially the same shape and size as the opening 11A of the battery housing 11. Further, an outer peripheral edge portion of the lid member 26 is formed with a circumferential engagement convex portion that relatively engages with the circumferential concave portion of the opening 11A. Further, on the inner side surface of the lid member 26, a pair of slide guide portions 27 that are opposed to each other in the width direction and are parallel to each other are integrally formed. These slide guide portions 27 are formed in an L shape in which the facing distance is substantially equal to the width dimension of the terminal member 21 and the cross-sectional shapes face each other.

The upper ends of the slide guides 27 extend to the arc-shaped upper edge of the lid member 26, and a pair of engaging pieces 28 projecting from the upper edge are provided in a protruding manner. As shown in FIG. 8, the lid member 26 formed in substantially the same shape as the opening 11A of the battery housing 11 has the opening 11A.

Even when the battery 10 is not housed therein, the battery lid 20 is rotated by the opening operation described later.

Embodiment Since the battery lid opening / closing mechanism of the portable radio receiver 1 is constructed as described above, when the battery 10 is exhausted or needs to be replaced, the lid member 26 is attached to the receiver. As shown in FIG. 2, along the side surface portion 2A of the main body 2,
Perform slide operation. As a result, the engagement state between the engagement piece 28 provided on the upper edge of the lid member 26 and the inner surface of the opening 11A is released. The elastic force of the connection terminal plate 15 acts on the terminal member 21 that slidably supports the lid member 26. When the locking state by the lid member 26 is released, the bearing portion 23 of the terminal member 21 has the bearing member 1
It is supported by 3 and rotates about the spindle 25 as a fulcrum in a counterclockwise direction as shown in FIG.

Therefore, the lid member 26 also rotates integrally with the terminal member 21 in the counterclockwise direction in FIG. 3, and the opening 11A of the battery housing portion 11 is largely opened.
The depleted battery 10 is taken out of the battery housing portion 11, and a new battery 10 is loaded from the negative terminal side of the battery housing portion 1.

As a result, the lid member 26 closes the opening 11A of the battery accommodating portion 11 and the engaging piece 28 relatively engages with the inner surface of the opening 11A and is held in the closed state.

In the opening / closing operation of the battery lid 20 described above, the lid member 26 should rotate integrally with the terminal member 21 in a state of being moved to the bottom surface side of the receiver body 2 as shown in FIG. Therefore, although the turning radius is small by the amount of sliding operation along the terminal member 21, the opening 11A can be largely opened by the same amount as when one end is used as the turning fulcrum. Therefore, the cover member 26 does not need a relief corresponding to the fulcrum portion, and can be configured to have a size substantially equal to the outer diameter dimension of the battery 20, and the ratio receiver 1 can be downsized. It should be noted that since the amount of protrusion of the battery cover 20 from the receiver body 2 in the open state is small, it does not become an obstacle and it is not necessary to increase the mechanical strength.

As described above, the battery lid 20 has the terminal member 21 having a terminal function of electrically connecting to the battery 10 housed in the battery housing portion 11, and the opening 11 of the battery housing portion 11.
Since it is configured by combining with the lid member 26 having the lid function of closing A, the occurrence of the inconvenience that the battery 20 is dropped and lost even when the battery 20 is opened for replacement, etc. To be prevented. Further, since the lid member 26 is reinforced by the terminal member 21, it is not necessary to increase the thickness dimension in order to particularly enhance the mechanical strength.

The opening / closing mechanism of the lid according to the present invention is not only applied to the opening / closing mechanism of the battery lid of the small electronic device described above, but, for example, as shown in FIG. 10, an earphone provided in the device body 30. Earphone storage unit 3 for storing 32
It is also used in the opening / closing mechanism of the lid 33 for opening / closing 1. The lid 33 that opens and closes the earphone storage unit 31 also has a structure that is easy to open and close, and is a structure that prevents the earphone storage unit 31 from being dropped and lost from the device body 30 in the open state. It is required that the structure does not increase the size by providing the relief portion.

Therefore, like the battery cover 20 shown as the first embodiment, the lid 33 also has a rotating member 35 rotatably supported with respect to the device body 30, and the rotating member 35. The lid member 36 is slidably supported with respect to the member 35. In this case, the rotating member 35 does not need to be formed of a metal plate, and may be formed of a synthetic resin material like the lid 33.

The lid 33, which opens and closes the earphone housing 31 constituted by the turning member 35 and the lid member 36, is rotated by the turning member 35 in a state where the lid member 36 is slid with respect to the device body 30. The earphone 32 is pulled out from the inside of the earphone storage unit 31 by the dynamic operation.
In the state where the earphone 32 is pulled out, the rotating member 35 is coupled and supported to the device body 30 via the support portion, and the lid member 36 is coupled and supported to the rotating member 35, so that the lid body is The 33 does not fall off the device body 30.

The structure of the rotating member 35 and the lid member 36, and the device body 30 that rotatably supports the lid 33 formed of the rotating member 35 and the lid member 36.
The specific structure of the supporting portion is the same as that of the battery lid 20 and the receiver main body 2 shown as the above-described first embodiment, and the detailed description thereof will be omitted.

Further, the opening / closing mechanism of the lid 33 for opening / closing the earphone housing 31 in which the earphone 32 is housed is as follows.
For example, it is also used for a lid opening / closing mechanism for opening / closing a storage portion for other connection cords.

[0035]

As described above in detail, according to the lid opening / closing mechanism of the present invention, the rotating member rotatably supported with respect to the equipment casing and the sliding member slides on the rotating member. The lid member is constituted by a freely supported lid member, and the lid member is slid with respect to the pivot member, whereby the pivot member also pivots to open the storage portion in which the stored object is stored. Since it is configured so that the lid can be opened and closed by a so-called one-touch operation, the operability is improved, and the lid does not drop from the device case even in the open state, so it is lost. There is nothing. Further, since the lid member is slidably operated with respect to the rotating member to rotate integrally with the rotating member at the position where the locked state with the housing is released, the rotation fulcrum portion is inside the member. Since it is not necessary to provide the rotation fulcrum portion on the outside, the rotation fulcrum portion can be formed in substantially the same shape as the opening portion of the storage portion, and the device can be downsized.

Further, the storage portion is configured as a battery storage portion for storing a battery, and the rotating member is configured as a terminal member with which a terminal portion of the battery stored in the battery storage portion comes into contact. By configuring the battery lid with the lid member provided with the locking means for holding the battery housing portion in the closed state, it is possible to configure the battery lid opening / closing mechanism having a structure with a small number of components as a whole. Further, since the connection terminal plate acts on the rotating member as a member that imparts a rotating habit to open the battery storage portion, members such as a coil spring are not required, and it is very suitable to be applied to a small portable device. .
