  FIG. 2 is a diagram showing the overlapping surfaces of the first casing 20 and the second casing 30, and FIG. 2A is an overlapping of the first casing 20 with the second casing 30. FIG. 2B is a view of the surface, that is, the case member 20b on the lower surface (back surface) of the first housing 20 as viewed from the lower surface side, and FIG. 2B is an overlapping surface of the second housing 30 with the first housing 20 That is, it is a view of the case member 30a on the upper surface (front surface) of the second housing 30 as viewed from the upper surface side.

  The case member 20b of the first housing 20 is provided with two guide holes, that is, the first guide hole 24 and the second guide hole 25, and the case member 30a of the second housing includes Two guide pins 32 and 33 are provided which engage with the two guide holes 24 and 25 and move in the respective holes.

The first guide hole 24 is formed to extend linearly along the longitudinal direction of the first casing, and the length is the amount of sliding movement of the first casing 20 in the longitudinal direction. It is length.

The second guide hole 25 extends in parallel with the first guide hole 24 and has a straight portion 25a having substantially the same length as the first guide hole 24. The straight portion 25a communicates with the straight portion 25a. An arc portion (arc guide hole) 25b extending in an arc shape toward the first guide hole 24 is formed. The arc portion 25 b has an arc shape with the upper end portion of the first guide hole 24 as the center point.

The second guide hole 25 is formed at a position where the central portion is substantially the center in the longitudinal direction of the first housing 20, and the first guide hole 24 is slightly more than the second guide hole 25. Are shifted downward by a predetermined amount.

The guide pins 32 and 33 provided on the case member 30a of the second housing are also shifted by the same amount as the shift length between the first guide hole 24 and the second guide hole 25. Thus, the guide pin 32 is disposed below the guide pin 33 by a predetermined amount.
FIG. 3A is a diagram illustrating the positions of the guide holes 24 and 25 when the first housing 20 is viewed from the display unit 21 side (front side). Note that the guide holes 24 and 25 are not visible when viewed from the display unit 21 side (front side), and therefore should be drawn with wavy lines on the drawing, but are drawn with solid lines for the sake of explanation.

FIG. 3B shows a state where the first casing 20 shown in FIG. 3A is connected to the second casing 30 and the casings 20 and 30 are closed (first casing). Engagement position between the guide holes 24 and 25 of the first housing 20 and the guide pins 32 and 33 of the second housing 30 when the body 20 is in a position that completely overlaps the second housing 30) FIG.

As is clear from this figure, the first guide pin 32 is in a position where the first casing 20 is closed with respect to the second casing 30 (a position that completely overlaps the second casing 30). Is formed so as to be positioned at the upper end of the first guide hole 24. The second guide pin 33 is formed in a positional relationship such that it is located at the upper end of the second guide hole 25.

FIG. 4 shows a connection structure between the first casing 20 and the second casing 30, and is a cross-sectional view taken along line AA in FIG.

In the figure, an opening 30b is formed in the case member 30a of the second housing 30, and a metal guide pin 33 is disposed so as to protrude from the opening 30b. A wide metal flange 33a is fixed to the end portion of the guide pin 33, and the flange portion 33a is fixed to the inner surface of the case member 30a.

The guide pin 33 protruding from the opening 30b is inserted into the guide hole 25 formed in the case member 20b of the first housing 20 and extends to the inside of the case member 20b, and the tip thereof is provided inside the case member 20b. It is attached to the received metal fitting 26.

The receiving metal fitting 26 is composed of a circular flange portion 26a and a circular receiving portion 26b formed on the lower surface of the circular flange portion 26a. The circular receiving portion 26b is a concave portion on the lower surface of the central portion thereof and the guide. The tip of the pin 33 is fixed. Further, the width (diameter) of the circular receiving portion 26b is formed larger than the hole width of the guide hole 25 as shown in the drawing.

In addition, a pair of guide plate members 27 and 27 are provided inside the case member 20b so as to sandwich the guide hole 25 along the guide hole 25, and the side surface of the circular flange portion 26a of the receiving metal fitting 26 is The guide plate members 27 and 27 can be moved along the guide plate members 27 and 27 while making point contact.

  In FIG. 4, the connecting portion by the guide hole 25 and the guide pin 33 has been described, but the connecting portion by the guide hole 24 and the guide pin 32 has the same configuration.

Next, the operation of the mobile phone 10 configured as described above will be described.

First, the operation in the case where the first housing 20 linearly slides in the longitudinal direction (upward direction in the drawing) with respect to the second housing 30 will be described with reference to FIGS. 5 and 6.

FIGS. 5A to 5C are external views (front views) showing a transition state of the housing when the first housing 20 is slid upward with respect to the second housing 30. FIGS. 6A to 6C are diagrams showing transition states of the guide holes 24 and 25 and the guide pins 32 and 33 which are connection mechanisms corresponding to FIGS. 5A to 5C.

As shown in FIG. 5A, in the closed state in which the first casing 20 and the second casing 30 are overlapped, the second casing 30 is all below the first casing 20. It is not seen in the front view. At this time, the guide holes 24 and 25 and the guide pins 32 and 33 are in the state shown in FIG.

That is, the guide pin 32 is located at the upper end of the guide hole 24, and the guide pin 33 is located at the upper end of the guide hole 25.

In the state shown in FIG. 5A, when a force is applied to the first casing 20 in the longitudinal direction (upward direction) with respect to the second casing 30, for example, the state shown in FIG. In a state where a certain mobile phone 10 is held with the right hand, when the first casing 20 is pushed upward with the thumb of the right hand (in the arrow Y direction), the first casing 20 moves upward.

At this time, the guide holes 24 and 25 formed in the case member 20b of the first housing 20 also move upward so that the guide pins 32 and 33 move relatively inside thereof. As a result, when moving to the position shown in FIG. 5B, the positional relationship between the guide holes 24 and 25 and the guide pins 32 and 33 is as shown in FIG. 6B.

When moving from the state shown in FIG. 5A to the state shown in FIG. 5B, the force pushing the first housing 20 is slightly shifted from right to left in the right direction. There are a case where a force that rotates the first housing 20 in the left-right direction with the guide pin 33 as a fulcrum and a case where a force in which the first housing 20 rotates in the left-right direction with the guide pin 32 as a fulcrum are generated.

However, when a force that rotates the first housing 20 in the left-right direction with the guide pin 33 as a fulcrum is applied, the guide hole 24 in which the guide pin 32 is located is formed in the vertical direction. Therefore, the force that the first casing 20 rotates in the left-right direction with the guide pin 33 as a fulcrum is canceled, and the first casing 20 is prevented from rotating in the left-right direction.

Even if a force that rotates the first housing 20 in the left-right direction with the guide pin 32 as a fulcrum is applied, the guide pin 33 is positioned obliquely above the guide pin 22. The guide hole 25 is pressed against the side opposite to the side where the arc portion 25b is formed, and the first housing 20 is prevented from rotating in the left-right direction.

Therefore, the guide pin 33 does not go in the direction of the circular arc portion 25b but moves relatively toward the inside of the straight portion 25a, and thereafter, as shown in FIG. The first housing 20 moves upward until the guide pins 32 and 33 are positioned at the lower ends, that is, until the state shown in FIG.

Next, an operation when the first housing 20 is slid clockwise with respect to the second housing 30 will be described with reference to FIGS. 7 and 8.

FIGS. 7A to 7C are diagrams showing transition states when the first housing 20 is slid clockwise with respect to the second housing 30, and FIGS. (C) is a figure which shows the transition state of the guide holes 24 and 25 which are a connection part, and the guide pins 32 and 33 corresponding to FIG. 7 (a) thru | or (c).

As shown in FIG. 7A, in the closed state where the first casing 20 and the second casing 30 are overlapped, the second casing 30 is entirely below the first casing 20. It is not seen in the front view. At this time, the guide holes 24 and 25 and the guide pins 32 and 33 are in the state shown in FIG.

That is, the guide pin 32 is located at the upper end of the guide hole 24, and the guide pin 33 is located at the upper end of the guide hole 25.

When force is applied clockwise from the lower end of the first casing 20 to the second casing 30 from the state of FIG. 7A, for example, the mobile phone in the state shown in FIG. When the telephone 10 is held with the right hand and the lower end of the first casing 20 is pushed up clockwise with the thumb of the right hand (arrow Z direction), the first casing 20 slides and rotates in the clockwise direction.

That is, when a clockwise force is applied to the lower end of the first housing 20, in the state shown in FIG. 8A, the rotational force with the guide pin 33 as the rotation center and the rotation with the guide pin 32 as the rotation center. The force acts, and the rotational force in the clockwise direction around the guide pin 33 is canceled because the guide pin is located at the upper end of the guide hole 24.

On the other hand, since the rotational force with the guide pin 32 as the rotation center has no structure to block it, the first housing 20 rotates clockwise with the guide pin 32 as the rotation center. That is, since the arc portion 25 b of the guide hole 25 is formed in an arc shape with the upper end of the guide hole 24 as the center, the guide pin 33 located at the tip of the guide hole 25 is positioned at the upper end of the guide hole 24. The inside of the circular arc part 25b is relatively moved with the guide pin 32 being used as a central rotation axis.

As a result, as shown in FIG. 8C, the one housing 20 rotates until the guide pin 33 reaches the tip of the arc portion 25b. As a result, the first housing 20 and the second housing 20 are rotated. 30 indicates that the first housing 20 is slid and rotated 90 degrees with respect to the second housing 30 as shown in FIG. 7C.

As described above, according to the above embodiment, the first housing 20 and the second housing 30 are closed (the first housing 20 is overlaid on the second housing 30). In addition to being capable of linearly sliding in one direction, the first casing 20 is rotated by 90 degrees with respect to the second casing 30 as it is at the starting position of the linear sliding movement. It can also be made.

Therefore, when using a telephone call function, mail function, etc., when inputting a telephone number or mail address or creating a mail text, the first housing 20 is slid linearly upward. Thus, the operation unit 31 can be exposed and a number, characters, etc. can be input immediately.

Further, when the one-seg television broadcast is received and the video is displayed, the first casing 20 and the second 30 are closed, and the first casing 20 is rotated as it is to display a vertically long display. The unit 21 can be set in the horizontally long state, and the video can be immediately viewed on the wide screen.

FIGS. 9A to 9C are diagrams showing modifications of the present invention.

  In the figure, the same components as those in the embodiment of FIGS. 1 to 8 are denoted by the same reference numerals, and detailed description thereof is omitted.

However, in the modified example of FIGS. 9A to 9C, in addition to the configuration of the embodiment of FIGS. 1 to 8, a third guide parallel to the guide hole 24 is formed on the lower surface of the first housing 20. A guide hole 28 is formed as a hole, and a guide pin 34 is provided as a third guide pin inserted through the guide hole 28 in the horizontal direction of the guide pin 32 on the upper surface of the second housing 30.

The guide hole 28 has a narrower hole width than the guide hole 24, and an arc portion 28 a centering on the upper end of the guide hole 24 is formed in the upper portion, and the tip of the arc portion 28 a is above the guide hole 24. It is formed to be (vertical direction).

The guide pin 34 is formed in a columnar shape, and the width of the column is substantially the same as the hole width of the guide hole 24. The guide pin 34 does not move in the hole width direction of the guide hole 24, but along the guide hole. Is configured to move.

In this configuration, in the closed state in which the first housing 20 and the second housing 30 are overlapped as shown in FIG. 32, 33, and 34 are in the state of FIG. 9A, and the first housing 20 and the second housing 30 are prevented from relatively moving or rotating in the left-right direction.

That is, the guide holes 24 and 25 and the guide pins 32 and 33 can prevent the horizontal movement or rotation to some extent, but the guide pins 32 and 33 move smoothly in the guide holes 24 and 25. Therefore, if the pin diameter is designed to be small to some extent with respect to the hole width of the guide hole, backlash occurs in the left-right direction or the rotation direction.

Therefore, a guide hole 28 and a guide pin 34 are newly provided and connected at three locations to prevent backlash.

When a force is applied clockwise from the state of FIG. 7A to the second housing 30 at the lower end of the first housing 20, the first housing 20 is as shown in FIG. 7B. Slides and rotates clockwise.

In this rotation state, the arc portion 28b above the guide hole 268 is formed from the lateral direction (horizontal direction) to the upward direction (vertical direction) of the upper end of the guide hole 24 with the upper end of the guide hole 24 as the center point. As shown in FIG. 9B, the guide pin 34 moves in the arc portion 28b around the guide pin 32 at the upper end of the guide hole 24.

At this time, since the pin diameter of the guide pin 34 is the same as the hole width of the guide hole 24 and does not move in the hole width direction, the first housing 20 has the guide pin 32 attached to the second housing 30. It can rotate smoothly without rattling as the center point. Then, when the guide pin 34 reaches the tip of the arc portion 28a as shown in FIG. 9 (c), the rotation is stopped, and the state is stably maintained in the state of FIG. 7 (c).

As described above, by providing the guide hole 28 and the guide pin 34, it is possible to prevent the first housing 20 and the second housing 30 from being shaken in both states. I can do it.

In the above embodiment, the first housing 20 is provided with the guide holes 24 and 25 and the second housing 30 is provided with the guide pins 32 and 33. However, the first housing 20 is provided with the guide holes. Guide pins 32 and 33 may be provided, and guide holes 24 and 25 may be provided in the second housing 30.

Alternatively, a guide hole and a guide pin may be provided in one housing, and a guide pin and a guide hole may be provided in the other housing so as to correspond to the guide hole and the guide pin may be inserted into the guide hole.

Furthermore, in the above embodiment, an example in which the present invention is applied to a mobile phone has been described. However, the present invention includes a plurality of cases such as a notebook computer, a wearable personal computer, an electronic dictionary, a PDA, a camera, and an electronic cam. The present invention can be applied to all electronic devices that perform a linear slide operation and a slide rotation operation.
