Herein, the recess portion 59 and the projection portion 171 are so formed to have a given margin respectively in size thereof, even when the recess portion 59 is obliquely inserted into the projection portion 171.
Subsequently, an opposite side to the side where the recess portion 59 is defined (the side where the latch portion 58 is defined) is pushed with the projection portion 171 and the recess portion 59 engaged with each other. Then, the arm portion 201 passes through a cutaway portion 58a, and the latch portion 58 and the push-out member 200 are in contact with each other, as shown in FIG. 14B. If a user releases his/her hands from the portable apparatus 10 in this state, the weight of the portable apparatus 10 causes the portable apparatus 10 to move downward slightly (in a depth direction of the drawing), so the engagement pin 202 of the push-out member 200 is engaged with a inner surface of the latch portion 58.
The push-out member 200 is biased by the torsion spring 203 in a counterclockwise direction in FIG. 12.
When the portable apparatus 10 is further pushed, the push-out member 200 is turned by the portable apparatus 10 (the latch portion 58) in an opposite direction to the biasing direction of the torsion spring 203. As shown in FIG. 14C, the latch portion 58 and the lock mechanism 190 are engaged and the portable apparatus 10 is attached to the housing portion 170. The lock mechanism 190 is biased by the torsion spring 193 in a clockwise direction in FIG. 14. Also, the lock mechanism 190 is provided with the engagement nail 191 protruding toward an external radial direction from the central axis thereof.
Accordingly, when the latch portion 58 and the lock mechanism 190 are engaged, the latch portion 58 pushes the engagement nail 191 in a counterclockwise direction, and then the lock mechanism 190 turns in a clockwise direction due to the biasing force and the engagement nail 191 is engaged with an inner surface of the latch portion 58. In this manner, the portable apparatus 10 is fixed to the housing portion 170 by the lock mechanism 190.
As stated heretofore, the portable apparatus 10 is attached to the housing portion 170, by turning the side where the latch portion 58 is formed, centering on the side where the recess portion 59 and the projection portion 171 are provided. That is to say, the portable apparatus 10 centers on the virtual axis line A indicated by a dotted line in FIG. 11.
The reason why one side of the portable apparatus 10 is centered on is this manner is to facilitate the attachment of the portable apparatus 10 into the housing portion 170. That is to say, when a user firstly inserts the side portion (where the recess portion 59 is defined) of the portable apparatus 10 into the housing portion 170, the recess portion 59 is engaged with the projection portion 171 and the portable apparatus 10 is positioned in the housing portion 170. By inserting the side, in which the latch portion 58 is defined, of the portable apparatus 10 in the afore-mentioned state, a user is able to attach the portable apparatus 10 into the housing portion 170 without touching the display portion 11 of the portable apparatus 10.
Next, a description will be given of the detachment of the portable apparatus 10 from the housing portion 170.
In order to detach the portable apparatus 10 from the housing portion 170, the detach button 160 is pushed. Then, the push portion 161 pushes the pushed portion 192, the lock mechanism 190 turns in a counterclockwise direction, and the latch portion 58 and the lock mechanism 190 are disengaged. By this, the push-out member 200 biases the portable apparatus 10 from the rear face to the front face of the portable apparatus 10, and the side in which the latch portion 58 is defined in the portable apparatus 10 is ejected from the housing portion 170. Hence, the push-out member 200 has a function of ejecting the portable apparatus 10 attached in the housing portion 170 from the housing portion 170.
Also, the arm portion 201 comes into contact with the cutaway portion 174, and then the push-out member 200 stops at a position shown in FIG. 14B. Additionally, at this time, by slightly moving the portable apparatus 10 downward (in a depth direction of FIG. 14B) according to the weight of the portable apparatus 10, the engagement pin 202 and the latch portion 58 are detachably engaged with each other. Therefore, the portable apparatus 10 maintains the state shown in FIG. 14B. A user is able to remove the portable apparatus 10 in the afore-mentioned state. Herein, the recess portion 59 and the projection portion 171 are also detachably engaged with each other with a given margin.
As stated heretofore, when the portable apparatus 10 is removed, the portable apparatus 10 centers on the side where the recess portion 59 is defined, namely, centers on the virtual axis line A indicated by a dotted line in FIG. 11.
The reason why the portable apparatus 10 is removed while centering on one side of the portable apparatus 10 is to prevent the portable apparatus 10 from dropping off from the housing portion 170. In other words, by detachably engaging the recess portion 59 and the projection portion 171, and the latch portion 58 and the engagement pin 202 respectively, as shown in FIG. 14B, the portable apparatus 10 is supported with the side in which the recess portion 59 is defined (hereinafter, referred to as one side) in the portable apparatus 10 housed in the housing portion 170 and with the side in which the latch portion 58 is defined (hereinafter, referred to as the other side) ejected, whereby the portable apparatus 10 can be prevented from dropping off from the housing portion 170.
In addition, the projection portion 171 has a function of guiding the portable apparatus 10 to revolve the other side of the portable apparatus 10 centering on one side thereof, when the portable apparatus 10 is attached or detached to and from the housing portion 170.
Furthermore, the projection portion 171 and the engagement pin 202 respectively have a function of detachably supporting the portable apparatus 10 with the portable apparatus 10 ejected from the housing portion 170. This facilitates the removal of the portable apparatus 10 from the in-vehicle apparatus 100.
Furthermore, the engagement pin 202 is integrally formed with the push-out member 200, thereby reducing the number of parts.
Also, as shown in FIG. 14B, when the portable apparatus 10 is supported with the other side of the portable apparatus 10 ejected from the housing portion 170, the engagement pin 202 maintains the engagement state with the latch portion 58 by the weight of the portable apparatus 10. Therefore, by moving the portable apparatus 10 slightly upward (in a front direction of FIG. 14B) and removing the portable apparatus 10 against the weight of the portable apparatus 10, the engagement state with the engagement pin 202 is easily disengaged and the portable apparatus 10 can be removed with ease.
In addition, at this time, the projection portion 171 and the engagement pin 202 support the portable apparatus 10 together, thereby enabling a stable support.
Also, the projection portion 171 is so formed to extend along one side of the portable apparatus 10 and guide the portable apparatus 10 to revolve. This makes it possible to guide the portable apparatus 10 to revolve with ease.
Furthermore, the housing portion 170 is defined in a recess shape, the projection portion 171 is formed in a protruding shape at an inner side of the housing portion 170, and the recess portion 59 in the portable apparatus 10 is defined in a recess shape. This can suppress the degradation in ease of grasp or appearance of the portable apparatus.
Next, the connector 150 will be described in detail.
The connector 150 and the connector 30 are fitted to each other and electrically connected, when the portable apparatus 10 is attached to the housing portion 170, and the connector 150 and the connector 30 release the fitting state, when the portable apparatus 10 is detached from the housing portion 170. Also, the connector 150 is a female connector and the connector 30 is a male connector.
Also, as shown in FIG. 11, the connector 150 is formed in the housing portion 170, and the connector 30 is formed at the corresponding position at the rear face of the portable apparatus 10, as shown in FIG. 8.
As described above, when the portable apparatus 10 is attached or detached to or from the housing portion 170, the portable apparatus 10 centers on the virtual axis line A indicated by a dotted line in FIG. 11. The connector 150 is formed to extend a longitudinal direction thereof along (in parallel with) the virtual axis line A at a position separate from the virtual axis line A. In other words, the connector 150 is provided closer to the other side of the portable apparatus 10 than to one side thereof attached in the housing portion 170.
Since the connector 150 is provided closer to the other side of the portable apparatus 10 than to one side thereof, the connector 150 and the connector 30 are easily fitted and released in accordance with the attachment or detachment of the portable apparatus 10 to or from the housing portion 170, as compared to a case where the connector 150 is provided closer to one side than to the other side. This is because the fitted and released directions of the connector 150 and 30 the connector 30 are straighter and the move amount of the one side of the portable apparatus 10 is greater than that of the other side thereof. Accordingly, the attachment and the detachment of the portable apparatus 10 to and from the housing portion 170 are facilitated.
Such facilitated attachment and detachment further facilitate the fitting and release of the connector 150 and the connector 30, thereby reducing unnecessary load to the connector 150 and the connector 30.
Also, the connector 150 is formed in a rectangular shape, and the longitudinal direction thereof is disposed to extend along (in parallel with) the virtual axis line A. With this configuration, it is possible to suppress angles of fitting and release of the connector 150 and the connector 30 to be changed depending on the positions (connection terminals) of the connector 150 and the connector 30, and it is also possible to suppress the change in the move amount in fitting and release depending on the position (connection terminal) of the connector 30. This ensures and facilitates the fitting and release of the connector 150 and the connector 30.
That is, when the longitudinal direction of the connector 150 is placed perpendicularly to the direction of the virtual axis line A, the move amount of the connection terminal is greater at the other side of the connector 30 and that of the connection terminal is smaller at one side thereof. The connection terminals at the other side are sequentially released. In the state shown in FIG. 14B, all the connection terminals are not released. However, if the longitudinal direction of the connector 150 is placed along (in parallel with) the direction of the virtual axis line A, all the connection terminals are released at the same time. Therefore, in the state shown in FIG. 14B, all the connection terminals will be released.
Also, the connector 150 is formed in the proximity of the push-out member 200. Accordingly, when the portable apparatus 10 attached is ejected from the housing portion 170, the push-out member 200 pushes the proximity of the connector 30.
With this configuration, the engagement of the connector 150 and the connector 30 can be released with power as small as possible.
Next, a description will be given of a position where the detach button 160 is formed.
The detach button 160, as shown in FIG. 11 and the like, is provided at the front face side of the front face portion 120, and the operating portion 132 and the housing portion 170 are provided at the front face side.
Also, the detach button 160 and the operating portion 132 are respectively provided at opposite sides interposing the housing portion 170. This can prevent the possibility of operating the detach button 160 mistakenly, while the operating portion 132 is being operated.
Since the operating portion 132 is located at the driver's side and the detach button 160 is located at the front-passenger's side, it is possible to prevent the possibility of operating the detach button 160 mistakenly, while a driver is steering or shifting.
As described above, the portable apparatus 10 housed in the housing portion 170 is ejected from the housing portion 170 at the other side of the portable apparatus 10, by operating the detach button 160. Also, the detach button 160 is provided closer to the other side of the portable apparatus 10 than to one side thereof. For this reason, immediately after the detach button 160 is operated, the other side of the portable apparatus 10 is ejected, thereby enabling the portable apparatus 10 to be removed by a successive operation after the detach button 160 is operated.
In addition, the detach button 160 is provided at an upper portion of the front face side of the front face portion 120. With this configuration, a passenger sitting on the front-passenger's seat or a driver is easily able to operate the detach button 160. Therefore, it is possible to remove the portable apparatus 10 easily.
In the present exemplary embodiment, when the portable apparatus 10 is attached or detached to or from the housing portion 170, the portable apparatus 10 is guided to revolve with one side as an axis. However, the present invention is not limited thereto. Another example is that the portable apparatus 10 may be attached in parallel with the housing portion 170, when attached, and the portable apparatus 10 may guided to revolve with one side as an axis, when detached.
Furthermore, in the present exemplary embodiment, the in-vehicle system 1 composed of the in-vehicle apparatus 100 and the portable apparatus 10 has been described; however, the present invention is not limited to the in-vehicle apparatus.
Furthermore, the portable apparatus 10 may be composed of a mobile telephone with the navigation functionality or a personal digital assistance (PDA). For example, if it is difficult to electrically connect a mobile telephone with the navigation functionality and an electronic apparatus, the electrical connection may be established by wireless communication (an example is Bluetooth) and the mobile telephone is housed in the electronic apparatus as a mechanical structure.
Furthermore, instead of the CD insertion/ejection slot 180 and the CD player 135, there may be provided an insertion/ejection slot and a player thereof for another memory media such as MD (Mini Disk), DVD (Digital Versatile Disk), SD memory card, or the like, and there may also provided insertion/ejection slots and players for multiple types of memory media.
Although a few specific exemplary embodiments employed in the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
