Abstract

PROBLEM TO BE SOLVED: To turn a movable member under low load state by moving the movable member to a position abutting on the rear surface when it is turned from horizontal or inclining attitude to a rising attitude thereby imparting a force for lifting the movable member to the rising attitude. SOLUTION: A reciprocal supporting member 23 is moved forward by turning a rotator 24 clockwise to project a movable member 10 outward of a case 1 in horizontal attitude. Under that state, the reciprocal support member 23 is retracted and the movable member 10 is shifted to a rising attitude. Furthermore, the lifting arm 16b of a lifting member 16 is entered between the rear surface of the movable member 10 in horizontal attitude and the bottom plate part 23a and a protrusion on the lifting arm 16b imparts a lifting force to the upper end 10c of the movable member 10. The movable member 10 can thereby be turned under low load state.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a display member and / or a display member.
Alternatively, the present invention relates to an electronic device in which a movable member having an operation member is turned to a standing posture in which a user can view or operate outside a case.

[0002]

2. Description of the Related Art In an electronic device for use in a vehicle, for home use, or for business use, a movable member having a display member and / or an operation member moves forward from a position housed in a case and moves outside the case. In some cases, the user can turn in a vertical or oblique direction so that the user can view or operate the device.

[0003] For example, Japanese Patent Application Laid-Open No. 1-266024 discloses a device for driving a recording medium and a CPU as a vehicle-mounted device.
There is disclosed an electronic device in which an electronic display unit is provided in front of a case containing the device. This electronic display unit can be projected forward from the state stored in the case,
Thereafter, the electronic display unit can be rotated in a vertical direction with its upper end as a fulcrum.

However, in the invention disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 1-266024, a structure in which the electronic display section is rotated downward about the upper end axis in a state where the electronic display section is pulled out of the case. It is. Therefore, since the position of the electronic display unit is lowered outside the case, the line of sight for viewing the display unit must be lowered, and the operation must be performed at a low position, which is inconvenient in use.

On the other hand, Japanese Patent Application Laid-Open No. 6-64484 discloses that the electronic display unit is rotated upward in front of the case.
Is disclosed in Japanese Patent Application Laid-Open Publication No. HEI 9-203 (1995). In the technique disclosed in this publication, by moving a fulcrum that supports the display member, the display member is rotated from a substantially horizontal posture to a rising posture upward.

[0006]

However, when the display member is rotated from the horizontal posture to the standing posture as described above, the display member is raised from the force applied to the fulcrum when the movable member is in the horizontal posture. The component force in the raising direction becomes very small, and the driving load when the display unit starts rising from the horizontal posture becomes very large. Therefore, when the display member is large, a large motor power is required for startup, and the operation is also confusing.

Further, the display member protrudes forward of the case in a substantially horizontal posture, and then the display member pivots in the rising direction. When the display member protrudes in the horizontal direction, the display member is positioned inside the case with respect to the display member. When the pushing force is improperly applied, the fulcrum may not move and the mechanism may be locked.

The present invention has been made to solve the above-mentioned conventional problems. First, when a movable member having a display portion or the like is turned from a horizontal posture or a slightly inclined posture to a rising posture,
It is an object of the present invention to provide an electronic device in which the movable member is easily rotated.

It is another object of the present invention to provide an electronic apparatus which can prevent a mechanism from being locked when an external force inwardly acting on a movable member protruding forward from a case in a horizontal posture. And

[0010]

According to the present invention, there is provided a case, a movable member having a display member and / or an operation member on a surface thereof, and the movable member being horizontal to the front of the case with respect to the front-rear direction of the case. And a posture control means for rotating the surface from a tilted posture to a rising posture in which the front surface faces the front of the case, wherein the movable member is rotated from the horizontal or inclined posture to the rising posture by the posture control means. A lifting member is provided which moves to a position where it comes into contact with the back surface of the movable member to apply a lifting force to the movable member in the rising posture direction.

In the present invention, when the movable member is rotated in the rising direction from a horizontal posture or a slightly inclined state, the lifting member for slightly lifting the back surface of the movable member is provided. Can be performed smoothly with a relatively low load.

For example, the attitude control means includes a reciprocating support member for moving the reciprocating support member in the front-rear direction while supporting the lower part of the movable member at a first support point and moving the reciprocating support member in the front-rear direction. A second support point for supporting the movable member above the first support point and rotating the movable member to the upright posture when the drive unit and the reciprocating support member retreat from the forward position toward the inside of the case; Having the lifting member, when the reciprocating support member retreats,
A lifting force is applied to the movable member in a rising posture direction by intervening between the back surface of the movable member and the reciprocating support member.

Further, when the reciprocating support member is moving forward in the front of the case, the movable member assumes a substantially horizontal posture with respect to the front-rear direction of the case, and the movable member is rotated from this horizontal posture to a rising posture. It is something that can be done.

According to the present invention, in the first retreating operation of the reciprocating support member, the movable member in the horizontal posture is rotated to the rising posture, and then the reciprocating support member moves forward to further perform the second retreating operation. And a distributing means for distributing the movement path of the second support point, so that the movable member is returned to the horizontal position and stored in the case when performing the lifting operation. (1) Intervening between the back surface of the movable member and the reciprocating support member during the retreat operation, and moving so as to be separated from the back surface of the movable member during the second retreat operation of the reciprocating support member. It is possible.

As described above, the present invention is applicable to a case where, for example, the movable member moves from the inside of the case to the front of the case in the horizontal posture, and then the movable member turns to the rising posture.
This is effective in smoothly performing the operation at the beginning of rising. Further, when the movable member is stored in the case in the horizontal posture by the second retreat operation of the reciprocating support member,
Since the lifting member is detached from the rear surface of the movable member, the movable member can surely be in a horizontal posture and move into the case without being affected by the lifting member.

However, the present invention is not limited to the case where the movable member is housed in the case, but the movable member is always located in front of the case, and the movable member is in a horizontal posture or a slightly inclined posture in front of the case. It may be one that rotates from the upright posture to the standing posture.

When the movable member is housed in the case as described above, the reciprocating support member is caused to perform forward and first retreat operations by the rotational power of the motor drive unit in the first direction. Motion conversion means for causing the reciprocating support member to perform a forward and a second retreat operation with the rotational power of the motor drive unit in the second direction, provided by the rotational power of the motor drive unit in the first direction, The lifting member may be operated in a direction to intervene between the back surface of the movable member and the reciprocating support member.

In this case, for example, the lifting member
The motion conversion means is rotatably supported by a reciprocating support member, and the motion converting means is provided with a rotating body reciprocally rotated by a motor drive unit, and And a cam portion on which the sliding portion moves, and when the motor driving portion rotates in the first direction,
When the lifting member is rotated in a direction intervening between the back surface of the movable member and the reciprocating support member by the rotational force of the rotating body, the rotating body is rotated when the motor driving unit rotates in a second direction. The lifting force allows the lifting member to be rotated in a direction away from the back surface of the movable member.

Further, the cam portion is provided on the reciprocating support member with a line connecting the rotation center of the rotating body and the sliding portion on a straight line parallel to the reciprocating direction of the reciprocating support member. It is possible to provide an inclined portion capable of giving a rotating moment to the rotating body when an inward external force is applied.

As described above, when the center of rotation of the rotating body and the connection point between the rotating body and the reciprocating support member are aligned in the direction of movement of the reciprocating support member, the movable member or the reciprocating support member is placed inside the case. When an external force is applied to the mechanism, the mechanism is likely to be locked. However, if an inclined portion is formed in the cam portion on which the sliding portion provided on the rotating body slides, when an external force is applied to the movable member inward of the case,
The sliding portion can move along the inclined portion, and the rotating body can rotate in either direction.
Therefore, it is possible to prevent the mechanism from being locked.

The lifting member 16 provided on the bottom plate 23a of FIG. 3 rotates counterclockwise, and the protrusion 16e provided on the lower surface of the lifting arm 16b fits into the first stopper recess 19a of the bottom plate 23a. Thus, the lifting member 16 is lightly locked.

When moving the movable member 10 from the standing position to the storage position, a storage operation button or the like provided on the control surface 10a of the movable member 10 is pressed. With this operation, the rotating body 24 is driven in the counterclockwise direction (second direction) by the motor 29 shown in FIG. When the posture from the standing posture to the storage posture is continuously performed, the rotator 24 is most rotated in the counterclockwise direction (second direction) as shown in FIG. 6 from the state of FIG. 4 through the state of FIG. State, and at this time, the motor 29 stops.

In the process of FIGS. 4, 5 and 6, the rotating arm 24b of the rotating body 24, the sliding pin 26 fixed thereto, and the driving cam portion 23e formed on the reciprocating support member 23 are constituted. The reciprocating support member 23 is moved one reciprocating motion by the motion converting means 27. FIG. 5 shows the reciprocating support member 23.
Is the position most protruding forward (Z1 direction), and the movable member 10 assumes the posture from FIG. 8A to FIG. 9A during the protruding operation of the reciprocating support member 23 from FIG. 4 to FIG. . Further, when the rotating body 24 rotates from the posture shown in FIGS. 5 to 6, the reciprocating support member 23 performs the second retreating operation, and the movable member 10
From the state shown in FIG. 9A to the storage posture shown in FIG. 9B.

First, in the first step in which the reciprocating support member 23 protrudes in the Z1 direction from the standing posture shown in FIGS. 4 and 8A, the reciprocating support member 23 linearly advances in the Z1 direction and switches the posture. Control pin 3 provided on arm 31
2 linearly advances in the Z1 direction in the rising posture guide portion 35a of the control plate portion 34a constituting the distribution means 22. Therefore, while the movable member 10 reaches the position shown in FIG.
The robot advances in the Z1 direction in parallel without tilting.

In FIG. 8B, the control pin 32 reaches the front end of the rising posture guide 35a, and the control pin 32 cannot move forward in the Z1 direction any more. Therefore, when the reciprocating support member 23 further advances in the Z1 direction, the first support pin 12 supporting the movable member 10 advances, and the second support pin 13 cannot further advance. The upper end of the movable member 10 (second
) Pivots downward (first side).

FIG. 8C shows a state where the movable member 10 is rotating. In this state, the control pin 32 slides in the linear guide portion 33 a formed on the reciprocating support member 23. The control pin 32 is located in a branch portion 35c of the distribution path 35 of the control plate portion 34a. FIG.
9 (A), the reciprocating support member 23
9A, the control pin 32 is located at the front end of the storage attitude guide portion 35b of the control plate portion 34a.
Therefore, in a state where the reciprocating support member 23 shown in FIG. 9A is most advanced, the movable member 10 has a horizontal posture in which the control surface 10a is directed perpendicular to the panel front surface 6.

When the reciprocating support member 23 retreats in the Z2 direction from FIG. 9A, the control pin 32 moves rearward (in the Z2 direction) along the storage attitude guide portion 35b of the control plate portion 34a. The member 10 is stored in the storage area 4 in the case 1 and the housing 2 while keeping the horizontal posture. FIG. 9 (B)
2, the end face of the lower end 10 b of the movable member 10 substantially coincides with the panel front face 6.

During the transition from FIG. 9A to FIG. 9B, the control pin 32 moves rearward in the storage attitude guide portion 35b of the distribution path 35 of the control plate portion 34a. The control pin 32 contacts the second sliding portion 43c on the lower side of the selection member 37 and slides. Therefore, the selection member 37 is rotated in the counterclockwise direction (F1 direction), and the small protrusion 39 provided at the rear end of the selection member 37 is disengaged from the lock portion 42 of the control plate portion 34a and enters the arc guide portion 41. . Accordingly, the light lock of the selection member 37 is released, and the selection member 37 can rotate around the support shaft 36 as a fulcrum within the movement range of the arc guide portion 41. However, it is always elastically urged in the counterclockwise direction (F1 direction) by the torsion spring 38.

As shown in FIGS. 4, 5 and 6, when the rotating body 24 rotates counterclockwise (second direction) and the reciprocating support member 23 performs the second retreating operation, As shown in FIG. 5, the sliding pin 26 provided on the rotating body 24
The lifting member 16 hits the second control arm 16d of the lifting member 16 and is rotated by the rotating body 24 in the counterclockwise direction.
Is rotated clockwise. When the sliding pin 26 comes off from the lifting member 16 as shown in FIG. 6, the projection 16e formed on the lifting arm 16b is fitted into the second stopper recess 19b, and the lifting member 16 is moved clockwise. Lightly locked in the rotated position.

Therefore, FIGS. 10A and 10B
As shown in FIG. 6, when the movable member 10 rotates to the horizontal posture, the lifting arm 16b of the lifting member 16
Moves to a position off the rear surface of the movable member 10. Therefore, the movable member 10 can approach or adhere to the bottom plate portion 23a of the reciprocating support member 23 without being disturbed by the lifting arm 16b, and can surely assume the horizontal posture.

In the above, the motor 29 is stopped by detecting that the rotating body 24 has reached the predetermined rotational position or by detecting that the reciprocating support member 23 has reached the predetermined moving position. 10 can be stopped in the inclined posture of FIG. 8C, or the movable member 10 can be stopped in the horizontal posture shown in FIG. 9A. In the state shown in FIG.
The control surface 10a of the movable member 10 is obliquely upward and the display member 11a provided on the control surface 10a can be seen, and the operation members 11b and 11c can be operated.

In FIG. 8C, the panel front surface 6 appears at a position adjacent to the upper end 10c of the movable member 10 stopped in the inclined posture, and the recording medium insertion / ejection opening 8 is located at a position adjacent to the upper end 10c. Is appearing. Therefore, the movable member 10
The recording medium (disc) can be inserted and ejected from above through the insertion / ejection port 8.

Further, as shown in FIG. 9A, when the movable member 10 is stopped in a state of protruding in a horizontal posture, the operation can be performed while looking at the upward control surface 10a of the movable member 10.

Further, as shown in FIG. 2, when the movable member 10 is housed in the case 1, the lower end surface 10b of the movable member 10 is substantially flush with the panel front surface 6, so that the entire panel front surface 6 is formed. It can be seen as one surface, and can be disguised as the movable member 10 has been removed from the panel front surface 6. Therefore, theft of the electronic device can be prevented.

Next, in order to make the movable member in the storage posture protrude to the standing posture, the rear end 10b of the movable member 10 is pushed in the storage posture of FIG. 6 and FIG. Is operated, or a switch provided on the front surface 6 of the panel is operated.

The motor 29 is started by these operations,
The rotating body 24 starts rotating clockwise (first direction).
When the rotating body 24 rotates to the position shown in FIG. 7, the reciprocating support member 23 moves forward (in the Z1 direction) most. During this time,
As shown in FIGS. 9B to 10A, the control pin 3
2 moves Z1 in the storage posture guide portion 35b of the control plate portion 34a.
Move forward in the direction. In addition, when the control pin 32 moves forward, it hits the second sliding portion 43c of the selection member 37, and thus the selection member 37 once rotates clockwise (F2 direction). However, this rotation range depends on the small projection 39 of the selection member 37.
Is within the range of movement in the arc guide portion 41 in the control plate portion 34a. Therefore, as shown in FIG. 10A, when the control pin 32 moves to the front end of the storage posture guide 35b and the control pin 32 comes off the selection member 37, the selection member 37 is moved counterclockwise by the torsion spring 38 ( (F1 direction), and the front end of the storage posture guide portion 35b is closed by the selection restricting portion 43a at the front end of the selection member 37. That is, the selection member 37 assumes the restricting posture.

When the rotating body 24 further rotates clockwise (first direction) from the state shown in FIG. 5, the reciprocating support member 23 performs the first retreating operation backward (Z2 direction).
As shown in (A), at this time, the control pin 32 is prevented from returning to the storage posture guiding portion 35b by the selection restricting portion 43a of the selecting member 37 in the restricting posture. Therefore, the control pin 32 is lifted by the downward inclined guide portion 33c formed on the reciprocating support member 23 that moves rearward, and moves to the branch portion 35c of the distribution path 35 provided on the control plate portion 34a (see FIG. B)). Therefore, when the reciprocating support member 23 performs the first retreating operation, the linear guide portion 33a of the reciprocating support member 23 slides on the control pin 32.

When the reciprocating support member 23 retreats, the control pin 32 is held in the branch portion 35c, and the first support pin 1 which is a connection point between the reciprocating support member 23 and the movable member 10 is provided.
Since 2 moves rearward, the upper end (the end on the second side) 10c of the movable member 10 is lifted upward. Therefore, FIG.
As shown in FIG. 0 (B), the movable member 10 is inclined and rotates counterclockwise. However, as shown in FIG. 11 (A), the upper inclined guide portion provided on the reciprocating support member 23. 33
b raises the control pin 32 and moves the control pin 32 to a height at which the control pin 32 can rise and enter the posture guiding section 35a. At this point, the movable member 10 is in a vertical position in which the control surface 10a is parallel to the panel front surface 6.

When the reciprocating support member 23 further retreats, as shown in FIG. 11A to FIG.
2 moves rearward in the rising posture guide portion 35a of the control plate portion 34a, and the movable member 10 becomes the rising posture that covers the panel front surface 6. 11B, the control pin 32 enters the groove 44 of the selection member 37 and hits the first sliding portion 43b. When the control pin 32 moves to the rear end of the rising posture guide portion 35a, the selection member 37 is rotated clockwise (F2 direction), and the small protrusion 39 comes out of the arc guide portion 41 and fits into the lock portion 42. Then, the selection member 37 enters the lightly locked state. At this time, the selection member 37 is in the restriction release posture, and the selection restriction portion 43a of the selection member 37 opens the storage posture guide portion 35b.

As described above, the selecting member 37 is connected to the arc guide 41
And the torsion spring 3
8 and is urged in the counterclockwise direction (F1 direction), and when it is turned clockwise, it is lightly locked by the lock portion 42. Since the selection member 37 is held in the restriction release posture by the light lock, FIGS.
During the period (A), the control pin 32 can enter the storage attitude guide portion 35b of the distribution path 35 of the control plate portion 34a. 9B to FIG. 10B, the control pin 32 is regulated by the selection restricting portion 43a of the selecting member 37 which is rotated counterclockwise and is in the restricting posture. 32 can be prevented from returning to the storage posture guide portion 35b, and the movable member 10 can be raised by retreating the reciprocating support member 23.

Further, from the storage posture shown in FIG.
When the rotating member 4 rotates clockwise (first direction), the sliding pin 26 provided on the rotating body 24 hits the first control arm 16 c of the lifting member 16 and is lifted by the rotating force of the rotating body 24. The member 16 is rotated counterclockwise. FIG. 7 shows, by a solid line, a halfway operation in which the lifting member 16 rotates counterclockwise. When the rotating body 24 further separates from the lifting member 16, as shown by a broken line in FIG. 7, the projection 16e of the lifting arm 16b fits into the first stopper recess 19a of the bottom plate 23a, and the lifting member 16
Is lightly locked in the position shown by the broken line in FIG. The posture of the lifting member 16 shown by the broken line in FIG. 7 is the same as the posture shown in FIG.

In FIG. 7, when the lifting member 16 reaches the solid line state and the broken line state, the lifting arm 16b intervenes between the upper end of the back surface of the movable member 10 and the bottom plate portion 23a, and the upper surface of the lifting arm 16b The lifting force acts on the upper end of the rear surface of the movable member 10 by a lifting force. Therefore, when the reciprocating support member 23 further performs the first retreating operation from the state of FIGS. 7 and 10A, the upper end 10c of the movable member 10 is easily turned upward.

That is, when the reciprocating support member 23 retreats in the Z2 direction from the state shown in FIG. 10A, a force in the Z2 direction is applied to the first support pin 12, and at this time, the second support pin 32 The movable member 1 is supported and regulated.
0 is rotated upward with the first support pin 12 as a fulcrum. As shown in FIG. 10A, when the movable member 10 is in the horizontal posture, the first support pin 12 and the second support pin 1
Of the forces applied to the movable member 3, the component force for rising and rotating the movable member 10 is extremely small, and when the weight of the movable member 10 is large, the movable member 10 is hard to rotate upward. However, when the reciprocating support member 23 retreats from the state of FIG. 7 and FIG.
By lifting the upper end of the movable member 10, the movable member 10 can be surely turned to the rising posture.

FIG. 12 shows a more preferable structure of the portion of the driving cam elongated hole 23e of the reciprocating support member 23. In FIG. 12, a regulating member 51 and the like are provided on the bottom plate 23a of the reciprocating support member 23. As shown in FIG. 4 and subsequent figures, the lifting member 16 is provided on the bottom plate portion 23a.
Is provided on the lower surface. When the lifting member 16 is not provided, the regulating member 51 and the like are connected to the bottom plate portion 23a.
It may be provided on the.

As shown in FIG. 12, an inclined portion 23e1 extending in the front Z1 direction is formed in the drive cam elongated hole 23e formed in the bottom plate portion 23a. In FIG. 12, the center axis 25 of the rotating body 24 and the sliding pin 26 are located on a straight line parallel to the Z1-Z2 direction. At this time, the position of the inclined portion 23e1 is determined so that the sliding pin 26 faces the inclined portion 23e1.

The regulating member 51 is rotatably supported by a shaft 52 on the bottom plate 23a. The regulating member 51 is urged clockwise by a torsion spring 53, and the stopper 54 regulates the rotation in the urging direction. When the regulating member 51 is in contact with the stopper 54, the side surface 51a on the Z2 side of the regulating member 51
It substantially coincides with the edge on the Z1 side of the drive cam slot 23e.

As shown in FIG. 12, when the center shaft 25 of the rotating body 24 and the slide pin 26 are located on the same line in the Z direction, as shown in FIG. 5 or FIG.
The movable member 10 is most advanced in the Z1 direction.

5, 7, and 12, when the movable member 10 or the reciprocating support member 23 is erroneously pressed and a pressing force is applied in the Z2 direction, the center shaft 25 and the sliding pin 2 are moved.
6, the rotating body 24 cannot rotate in either direction, and the mechanism is locked.

However, in FIG. 12, since the sliding pin 26 hits the inclined portion 23e1 of the drive cam slot 23e, when the force in the Z2 direction acts on the reciprocating support member 23, the sliding pin 26 The rotating body 24 can rotate in the counterclockwise direction by sliding on the inclined portion 23e1. In particular, if a slip clutch is provided in any part of the power transmission path from the motor 29 to the rotating body 24, for example, the pinion gear 28a, the rotating body 24 can easily rotate counterclockwise and the mechanism locks. Can be prevented.

When the sliding pin 26 slides on the inclined portion 23e1, the regulating member 51 rotates counterclockwise. When no external force is applied to the reciprocating support member 23 or the movable member 10 in the Z2 direction, the regulating member 51 is in contact with the stopper 54, and the sliding pin 26 slides on the side surface 51a of the regulating member 51. Therefore, rattling in the Z direction does not occur between the sliding pin 26 and the reciprocating support member 23.

[0098]

As described above, according to the present invention, when the movable member provided with the display member and / or the operating member rotates from the horizontal posture or the inclined posture to the rising posture, the lifting force is applied to the movable member. Because of the action, the movable member surely rotates to the rising posture. Therefore, even if the movable member is large and heavy, the movable member can be rotated with a relatively low load.
