Description

  Embodiments relate to an electronic apparatus having a movable display unit.

  2. Description of the Related Art In recent years, many electronic devices such as a mobile phone and a mobile terminal device have a first housing serving as a main body and a second housing having a display portion. Usually, the second housing having the display portion is attached to be movable (slidable) or rotatable with respect to the first housing serving as the main body. For example, the input device of the first casing can be exposed by sliding the second casing with respect to the first casing. As a result, the user can operate the input device while viewing the screen of the display unit of the second casing to cause the electronic device to perform a desired operation.

Including. FIG. 1 shows a state in which the second casing 20 is disposed and accommodated on the first casing 10, that is, the most compact state. In this state, the second display portion 20a of the second housing 20 is exposed as an upper surface. The first display unit 10a and the second display unit 20a are, for example, liquid crystal display devices with a touch panel, and can perform screen display and input operations. In particular, the first display unit 10a functions as an input operation unit. However, the input operation unit may not be a liquid crystal display device with a touch panel like the first display unit 10a, and may be an input device such as a numeric keypad.

  The portable information device 1 can be slid with respect to the first casing 10 by pushing the second casing 20 in the arrow A direction from the state shown in FIG. The slide guide mechanism will be described later. FIG. 2 is a perspective view showing a state in which the second housing 20 is being slid. The second housing 20 slides parallel to the upper surface of the first housing 10. As the second housing 20 slides, the first display unit 10a on the upper surface of the first housing 10 appears.

  FIG. 3 is a perspective view showing a state in which the second housing 20 is completely slid. The second housing 20 slides to a position where the entire second housing 20 does not overlap the upper surface (first surface) of the first housing 10, and the side surface 20 b of the second housing 20 is the upper surface of the first housing 10. Slide to a position slightly beyond the edge. In this state, the display unit 20a on the upper surface of the second housing 20 is positioned above the first display unit 10a on the upper surface of the first housing 10 by the thickness of the second housing. There is a step between the first display unit 10a and the second display unit 20a.

  In this embodiment, the slide guide mechanism has a first slide guide mechanism and a second slide guide mechanism. The second slide guide mechanism includes a rotation mechanism.

  First, the first slide guide mechanism will be described. The first slide guide mechanism includes a pair of slide guides (rail members) 12 provided in the first housing 10 and a pair of slide blocks 14 that can slide on the slide guide 12. A slide assist member 16 is connected to each slide block 14 as a biasing member that biases the slide block 14. 5, 7, 9, and 11, the same slide guide mechanism is provided symmetrically on the left and right, but only one of them will be described with reference numerals.

  The slide guides 12 are elongate rail members having a trapezoidal cross section, for example, and are respectively disposed on the left and right sides inside the first housing 10. The slide block 14 includes a block portion 14a that engages with the slide guide 12, an arm portion 14b that extends from the block portion 14a, and a guide portion 14c that is provided at the tip of the arm portion 14b.

  A slide assist member 16 for assisting the sliding movement of the block portion 14a is connected to the block portion 14a of the slide block 14. The slide assist member 16 includes two compression springs. By accumulating the repulsive force in the compression spring, the block portion 14 a of the slide block 14 is biased toward the front end portion or the rear end portion of the slide guide 12 by the accumulated repulsive force. Here, the front means the front side in the direction in which the second housing 20 slides (arrow A direction), and the rear means the side in the sliding direction.

  A second slide guide mechanism is formed in the guide portion 14 c of the slide block 14. The second slide guide mechanism has a guide portion 14c and a rotary shaft 30 that is slidably engaged with a groove formed in the guide portion 14c. The groove formed in the guide portion 14c extends in the extending direction of the slide block, that is, in the sliding direction (arrow A direction). Therefore, the rotating shaft 30 engaged with the groove formed in the guide portion 14c can slide in the sliding direction (arrow A direction).

  A shaft portion 30 a of the rotating shaft 30 is inserted into a shaft hole (not shown) formed in the second housing 20, and the second housing 20 rotates around the shaft portion 30 a of the rotating shaft 30. It is possible to move. In addition, a spring 32 that biases the second housing 20 in a direction opposite to the sliding direction (the direction of arrow A) is provided in the vicinity of the rotation shaft 30. One end of the spring 32 is fixed near the shaft hole of the second housing 20, and the other end is fixed to the arm portion 14 b of the slide block 14. When the second housing 20 slides and the rotation shaft 30 moves in the sliding direction (arrow A direction) along the groove of the guide portion 14c, the spring 32 is pulled. Therefore, when the second casing 20 slides in the direction of arrow A, the second casing 20 is in a direction opposite to the sliding direction due to the force of the spring 32 returning, that is, a direction toward the first casing 10. Be energized by.

  The second housing 20 can be tilted with respect to the first housing 10 by rotating around the shaft portion 30 a of the rotation shaft 30. This structure corresponds to a rotation mechanism. Note that the direction in which the spring 32 pulls the second housing 20 is inclined downward with respect to the sliding direction. For this reason, the pulling force of the spring 32 includes a force for rotating the side surface 20b of the second housing 20 downward.

  Next, an operation when the second housing 20 is slid to be used will be described.

  When the second housing 20 overlaps the first housing 10, that is, in the state shown in FIGS. 5 and 6, the block portion 14a of the slide block 14 is located at the front end portion of the slide guide 12, The slide assist member 16 is biased by a compression spring in a direction opposite to the slide direction. The position of the second casing 20 at this time, that is, the position shown in FIGS. 5 and 6 is defined as the first position of the second casing. The second housing is biased to the position shown in FIGS. 5 and 6 so as not to move easily in the sliding direction (arrow A direction). That is, the second housing 20 is biased so as to maintain the position shown in FIGS.

  In this state, a part of the guide part 14c and the arm part 14b of the slide block 14 and a part of the spring 32 are an opening formed in the first casing 10 and an opening formed in the second casing 20. And enters the second housing 20.

  When a force is applied to the second housing against the urging force of the slide assist member 16 in the slide direction (arrow A direction), the block portion 14a of the slide block 14 moves along the slide guide 12, Two housings 20 slide parallel to the first housing 10. When force is applied as it is, the slide assist member 16 rotates around the fulcrum 16a, and the distance between the fulcrum 16a and the end connected to the block part 14a on the opposite side becomes smaller. Therefore, the compression spring of the slide assist member 16 is compressed and the repulsive force is stored.

  When the line between the fulcrum 16a of the slide assist member 16 and the end connected to the block portion 14a passes through a position perpendicular to the slide direction, this time, the repulsion accumulated in the compression spring of the slide assist member 16 The force is a force that pushes the block portion 14a in the sliding direction. Accordingly, the block 14a is urged in the sliding direction, and the second casing 20 automatically slides in the sliding direction.

  When the block portion 14a slides to the rear end portion of the slide guide 12, the slide guide mechanism is in the state shown in FIGS. In this state, the arm portion 14 b and the guide portion 14 c of the slide block 14 are extended from the side surface of the first housing 10. Note that the shaft portion 30 a of the rotating shaft 30 is inserted into the shaft hole of the second housing 20 while the guide portion 14 c is housed in a groove formed on the lower surface of the second housing 20. .

  Due to the urging force of the slide assist member 16, the second housing 20 is automatically arranged at the position shown in FIGS. The position of the second housing 20 at this time, that is, the position shown in FIGS. 7 and 8 is defined as the second position. A force is applied to the second casing 20 from this position, and the second casing 20 is further slid. The rotation shaft 30 fixed to the second housing 20 is guided along the groove of the guide portion 14c and the rotation shaft 30 slides, whereby the second housing 20 can slide. At this time, since the second casing 20 slides while pulling the spring 32, the spring 32 accumulates a force for pulling in the direction opposite to the sliding direction.

  When the rotary shaft 30 slides in the sliding direction and is positioned at the rear end portion of the groove of the guide portion 14c, the side surface 20b of the second housing 20 exceeds the side surface 10b of the first housing 10 and is second. The entire housing 20 does not overlap the upper surface of the first housing 10. The position of the second casing 20 at this time, that is, the position shown in FIGS. 9 and 10 is defined as the third position of the second casing. As a result, as shown in FIGS. 9 and 10, the entire second casing 20 comes out of the outer periphery of the first casing 10. In this state, the second housing 20 is supported only by the shaft portion 30 a of the rotating shaft 30 and is rotatable. The second housing 20 is pulled in the direction toward the first housing 10 by the spring 32, and the pulling direction of the spring 32 is inclined downward with respect to the sliding direction. For this reason, the component force of the pulling force of the spring 32 is a force that moves the side surface 20b of the second housing 20 downward. As a result, the second housing 20 rotates around the shaft portion 30a of the rotating shaft 30, the side surface 20b moves (lowers) in the direction of arrow B in FIG. 9, and the opposite side of the side surface 20b moves to the arrow in FIG. Move (rise) in the direction of C.

  Below the second housing 20, there is an arm portion 14 b of the slide block 14 extending from the inside of the first housing 10. The arm part 14b is inclined at a predetermined angle with respect to the sliding direction (that is, the direction parallel to the upper surface of the first housing 10). When the second casing 20 rotates about the shaft portion 30a of the rotation shaft 30 as described above, the arm portion 14b enters the groove portion 20c formed on the lower surface of the second casing 20, and the second casing 20 enters. The rotation of the body 20 stops. In this state, as shown in FIGS. 11 and 12, the height of the edge between the upper surface of the second housing 20 and the side surface 20b is between the upper surface of the first housing 10 and the side surface 10a. It becomes the same as the height of the edge. That is, when the second housing 20 is inclined, there is no step between the upper surface of the first housing 10 and the upper surface of the second housing 20.

  In the state where the second casing 20 is inclined as shown in FIGS. 11 and 12, the second casing 20 is biased by the spring 32 in the direction toward the first casing 10, The side surface 20b of the second housing 20 is pressed against the side surface 10b of the first housing. Therefore, the second housing is fixed at this position.

  With the above operation, the second display portion 20a on the upper surface of the second housing 20 and the first display portion 10a on the upper surface of the first housing 10 are exposed, and the portable information device 1 can be operated. Become.

  In order to return the second casing 20 to the state shown in FIGS. 7 and 8, the second casing 20 is tilted and lowered by pushing up the side surface 20b side of the second casing 20 from below to return the tilt. The casing 20 is parallel to the upper surface of the first casing 10. As a result, the second casing 20 is pulled by the spring 32 and automatically slides in the direction opposite to the arrow A direction, and returns to the state shown in FIGS.

  When the state shown in FIGS. 7 and 8 is restored, a force may be applied to the second housing 20 in the direction opposite to the arrow A direction to return to the state shown in FIGS. At this time, due to the action of the slide assist member 16, the second housing 20 is biased to the position shown in FIG. 5 and FIG. 6 from the point of sliding to some extent, and automatically returns to the original position. .
