An embodiment of an electronic device according to an embodiment will be hereinafter described in detail with reference to attached drawings. The following deals with a laptop PC in which a tablet PC is attached to a station, as an example, but the embodiments are not limited to the laptop PC in which the tablet PC is attached to the station.

FIG. 1 is a perspective view illustrating a laptop PC according to an embodiment, and FIG. 2 is a perspective view illustrating a state where an opening and closing body of the laptop PC illustrated in FIG. 1 is closed. Further, FIG. 3 is a side view illustrating the state where the opening and closing body of the laptop PC illustrated in FIG. 1 is closed, in which side view a cover is omitted.

As illustrated in FIGS. 1 and 2, a laptop PC 1 according to an embodiment is configured such that a tablet PC 2 is attached to a station 3.

Since the tablet PC 2 is used solely, the tablet PC 2 is provided with a control board (not shown), a battery (not shown), and so on as well as a display 21, and is larger in weight than a cover of a conventional laptop PC.

As illustrated in FIG. 1, the station 3 includes a station body 4, and an attachment portion 5 to which the tablet PC 2 is attached. The station body 4 is a portion which is placed on a desk or a knee at the time of use and serves as a base body, and the attachment portion 5 is a portion to which the tablet PC 2 is attached, and the attachment portion 5 and the tablet PC 2 serve as an opening and closing body provided to be openable and closable with respect to the base body.

The station body 4 includes a keyboard 43 constituted by an operation key 41 and a touch pad 42 and provided on a top face thereon, and the attachment portion 5 includes a connector (not shown) to be connected to the tablet PC 2. Hereby, the keyboard 43 provided on the top face of the station body 4 strengthens an input function of the tablet PC 2 attached to the attachment portion 5.

As illustrated in FIG. 3, the attachment portion 5 is attached to the station body 4 rotatably, and a shaft (only a “shaft center O” of the shaft is illustrated) for rotatably supporting the attachment portion 5 is placed on the station body 4 so that a depth L of the station body 4 remains behind the shaft. Thus, the laptop PC 1 according to the present embodiment is configured as an electronic device in which a shaft provided to be openable and closable with respect to a base body is placed on the base body so that a depth of the base body remains behind the shaft.

In the laptop PC 1 in which the shaft is placed on the station body 4 so that the depth L of the station body 4 remains behind the shaft as such, even if the tablet PC 2 thus attached is larger in weight than the cover of the conventional laptop PC, the tablet PC 2 is supported by an area (the depth L) behind the shaft, so that the laptop PC 1 does not turn over on a tablet-PC-2 side.

FIGS. 4 to 7 are expanded sectional views each illustrating an essential part of the laptop PC illustrated in FIG. 1. As illustrated in FIGS. 4 to 7, a stepped portion 44 is provided on the top face of the station body 4 and behind the shaft (only the “shaft center O” of the shaft is illustrated). The stepped portion 44 is configured to prevent a step from occurring between the station body 4 and the attachment portion 5 when the tablet PC 2 is closed with respect to the station body 4, and includes an inclined surface 44a provided on a shaft side. The inclined surface 44a is configured to form a space where the attachment portion 5 rotates. An inclination angle of the inclined surface 44a defines an openable angle of the tablet PC 2, and when the tablet PC 2 is closed with respect to the station body 4, a V-shaped groove (space) G is caused between the inclined surface 44a and the attachment portion 5. In the present embodiment, the openable angle of the tablet PC 2 is defined to 135 degrees, so that the tablet PC 2 is openable by any degree between 0 degrees to 135 degrees with respect to the station body 4.

As illustrated in FIG. 2, a cover 6 made from resin is provided at a back side on the top face of the station body 4. The cover 6 is configured to cover a depth portion remaining behind the shaft. The cover 6 has a size that covers the depth portion remaining behind the shaft, namely, the stepped portion 44 and the V-shaped groove G, and the attachment portion 5, and a thickness that allows an outer surface 6A to be placed on the same plane as an outer surface 2A of the tablet PC 2 when the cover 6 covers the depth portion remaining behind the shaft.

FIG. 8 is a sectional view illustrating a relationship between the cover and a cover shaft for supporting the cover, and FIG. 9 is a view illustrating a state where the cover is removed from the cover shaft. As illustrated in FIG. 8, a shaft hole 6b is formed in the cover 6, so that the cover 6 is supported by a cover shaft 45 (only a “shaft center O₂” of the cover shaft is illustrated in FIGS. 4 to 7) provided in a rear edge of the stepped portion 44 provided behind the shaft (see FIG. 4). The cover 6 is hereby openable and closable when the tablet PC 2 is closed with respect to the station body 4. When the cover 6 is closed with respect to the depth portion remaining behind the shaft as illustrated in FIG. 4, the depth portion remaining behind the shaft, namely, the stepped portion 44 and the V-shaped groove G, and the attachment portion 5 are covered, and the outer surface 6A of the cover 6 is placed on the same plane as the outer surface 2A of the tablet PC 2. As a result, the laptop PC 1 according to an embodiment is configured as an electronic device including a cover which is supported behind a shaft, which is openable and closable when an opening and closing body is closed, which is configured such that its outer surface is placed on the same plane as an outer surface of the opening and closing body when the cover is closed, and which covers that depth portion of a base body which remains behind the shaft.

In the meantime, as illustrated in FIG. 8, a fitting margin L₂ for the shaft hole 6b provided on the cover 6 and the cover shaft 45 is set so that the cover 6 is removed from the cover shaft 45 when a force of more than a predetermined magnitude works on the cover 6 in a state where the cover 6 is opened (see FIG. 9). A force of the predetermined magnitude is 3 kgf, for example, and in this case, when a force of more than 3 kgf works on the cover 6 in the state where the cover 6 is opened, the cover 6 is removed from the cover shaft 45. Hereby, the laptop PC 1 according to the an embodiment is configured as an electronic device in which a cover is supported by a cover shaft so that the cover is removed from the cover shaft when a force of more than a predetermined magnitude works on the cover in a state where the cover is opened.

FIG. 10 is a view illustrating a state where the cover is opened and illustrating an opening and closing mechanism. As illustrated in FIG. 10, an opening and closing mechanism 7 is provided between the attachment portion 5 and the cover 6. The opening and closing mechanism 7 is configured to open the cover 6 being closed, when the tablet PC 2 is opened from its closed state, and to close the cover 6 being opened, when the tablet PC 2 is closed from its opened state. The opening and closing mechanism 7 includes link mechanisms 8 and connection means 9 at two places in a width direction of the station body 4. Thus, the laptop PC 1 according to an embodiment is configured as an electronic device including an opening and closing mechanism provided between an opening and closing body and a cover, and configured to open the cover being closed, when the opening and closing body is opened from its closed state, and to close the cover being opened, when the opening and closing body is closed from its opened state.

The link mechanism 8 is configured to open the cover 6 being closed, by pressing the cover 6 thus closed, when the tablet PC 2 is opened from the closed state. The link mechanism 8 is constituted by combining one end of a metal tabular body 81 and one end of a metal striped body 82. This allows the tabular body 81 to rotate relative to the striped body 82 and the striped body 82 to rotate relative to the tabular body 81. Further, the other end of the tabular body 81 is supported by the stepped portion 44 provided in the station body 4, and the other end of the striped body 82 is supported by the attachment portion 5. Accordingly, as illustrated in FIG. 4, the one end of the tabular body 81 is accommodated in a recessed portion 5a provided in the attachment portion 5 in a state where the tablet PC 2 is closed, and as illustrated in FIGS. 5 to 7, when the tablet PC 2 is opened from its closed state, the one end of the tabular body 81 projects outside the attachment portion 5 from the recessed portion 5a of the attachment portion 5.

The connection means 9 is configured to close the cover 6 being opened, when the tablet PC 2 is closed from its opened state, and as illustrated in FIG. 10, the connection means 9 is constituted by the tabular body 81 and a magnet 91 provided in the cover 6 at a position opposite to the tabular body 81. Hereby, the magnet 91 provided in the cover 6 adheres to the tabular body 81. When the tablet PC 2 is closed from the opened state, the cover 6 being opened is closed in association with the attachment portion 5.

FIG. 11 is a view illustrating a hitch provided on a right side surface of the stepped portion. As illustrated in FIG. 11, a hitch 46 is provided on a right side surface of the stepped portion 44. The hitch 46 is configured to connect a security lock (not shown) thereto. The hitch 46 is drawable in a state where the cover 6 is opened, and the cover 6 is closable in a state where the hitch 46 is drawn.

As illustrated in FIG. 4, the laptop PC 1 according to the aforementioned embodiment is configured such that the cover 6 is closed in association with a closing operation on the tablet PC 2. More specifically, the one end of the tabular body 81 constituting the link mechanism 8 is accommodated in the recessed portion 5a of the attachment portion 5 from outside the attachment portion 5 by the closing operation on the tablet PC 2, and in association with this, the cover 6 is moved from an open position to a closed position in a state where the magnet 91 provided in the cover 6 adheres to the one end of the tabular body 81. Hereby, the cover 6 is closed when the tablet PC 2 is closed with respect to the station body 4. At this time, the depth portion of the station body 4 which depth portion remains behind the shaft for supporting the attachment portion 5 to which the tablet PC 2 is attached, namely, the stepped portion 44 and the V-shaped groove G, and the attachment portion 5 are covered, and the outer surface 6A of the cover 6 is placed on the same plane as the outer surface 2A of the tablet PC 2.

Thus, the cover 6 is independently openable and closable in a state where the tablet PC 2 is closed with respect to the station body 4, and when an open operation is performed on the cover 6 against an attractive force of the magnet 91 provided in the cover 6 with respect to the tabular body 81, the cover 6 is openable independently. This allows the hitch 46 to be drawable as illustrated in FIG. 11, and when the hitch 46 is drawn, the security lock is connectable.

Further, as illustrated in FIG. 9, in a case where a force of more than the predetermined force works on the cover 6 in a state where the cover 6 is opened, the shaft hole 6b provided in the cover 6 is removed from the cover shaft 45, so that the cover 6 is removed from the stepped portion 44 of the station body 4.

Meanwhile, as illustrated in FIGS. 5 to 7, the cover 6 is opened in association with an open operation of the tablet PC 2. More specifically, by the open operation on the tablet PC 2, the one end of the tabular body 81 constituting the link mechanism 8 projects outside the attachment portion 5 from the recessed portion 5a of the attachment portion 5. In association with this, the one end of the tabular body 81 presses the magnet 91 provided in the cover 6, and in a state where the magnet 91 provided in the cover 6 adheres to the one end of the tabular body 81, the one end of the tabular body 81 presses the cover 6 (the magnet 91 provided in the cover 6), so that the cover 6 is moved from the closed position to the open position. Hereby, the cover 6 is opened when the tablet PC 2 is opened with respect to the station body 4.

The laptop PC 1 according to the aforementioned embodiment includes the cover 6 which is supported behind the shaft, which is openable and closable when the tablet PC 2 is closed, which is configured such that its outer surface is placed on the same plane as the outer surface 2A of the tablet PC 2 when the cover is closed, and which covers the depth portion of the station body 4 which depth portion remains behind the shaft, namely, the stepped portion 44 and the V-shaped groove G, and the attachment portion 5. Accordingly, this improves an appearance at the time of closing the tablet PC 2 of the laptop PC 1 in which the shaft is placed on the station body 4.

Further, when a force of more than a predetermined force works on the cover 6 in a state where the cover 6 is opened, the cover 6 is removed from the cover shaft 45. In view of this, even if an excessive force works on the cover 6, the cover made from resin cannot be broken.

Further, the laptop PC 1 includes the opening and closing mechanism 7 configured to open the cover 6 being closed, when the tablet PC 2 is opened from its closed state, and to close the cover 6 being opened, when the tablet PC 2 is closed from its opened state. Accordingly, it is not necessary to perform an open operation on the cover 6 independently from an open operation on the tablet PC 2, and it is not necessary to perform a closing operation on the cover 6 independently from a closing operation on the tablet PC 2.

The laptop PC 1 according to the aforementioned embodiment is configured such that the tablet PC 2 is attached to the station 3. However, the laptop PC 1 may be an electronic device in which a shaft for supporting an opening and closing body is placed on a base body so that a depth of the base body remains behind the shaft, and may be, for example, a laptop PC in which a shaft for supporting a cover body is placed on a main body of the PC so that a depth of the main body of the PC remains behind the shaft.

Further, the laptop PC 1 according to the aforementioned embodiment is configured such that the connection means 9 is constituted by the metal tabular body 81 constituting the link mechanism 8, and the magnet 91 provided in the cover 6 so as to be opposed to the tabular body 81. However, the laptop PC 1 may be constituted, for example, by attaching, around the cover shaft, a torsion coiled spring which always biases the cover 6 in a closing direction.
