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 provided with an operation member is moved forward and backward of a case, and more particularly to an electronic device capable of preventing rattling of a movable member.

[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 provided with a display member and / or an operation member moves forward from a position stored in a case to move the case. There are some that go outside and then rotate in a vertical or oblique direction so that the user can view or operate.

[0003] Alternatively, in some cases, the movable member protrudes forward from the case in a horizontal position from the inside of the case, and an operating section provided on the movable member can be operated in that position.

[0004]

However, as described above, in the case where the movable member has the movable mechanism that moves forward of the case, the sliding portion and the rotation fulcrum of the movable mechanism are mechanically mounted. It is impossible to avoid rattling. This rattling may cause the movable part to slightly move when the operation member of the movable part is pressed by hand, thereby deteriorating the operation feeling. Also, in the case of an electronic device mounted on a vehicle, noise may be generated in the mechanically rattling portion due to the vibration of the vehicle body.

Therefore, an elastic biasing force can be applied to any part of the movable mechanism to absorb the mechanical play by the elastic biasing force. However, when the elastic biasing force is applied, the biasing force acts on the components constituting the movable mechanism in one direction, and as a result, each part of the movable mechanism may not operate reliably. For example, when the left and right sides of the movable member are simultaneously latched by the latching means when the movable member projects forward of the case, only the one side is latched by the latching means by the biasing force. Therefore, a state may occur in which the other side is not securely locked and the operation cannot be completed reliably.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide an electronic device which prevents rattling of a movable member and allows each mechanism to operate reliably.

Is located at the Z2 side end of the upper facing posture guide portion 35a in the distribution path 35 formed at the bottom. Further, the control pin 32 slides on the first sliding portion 43b of the engaging members 37A and 37B and enters the groove 44. Therefore, the locking members 37A, 37B are rotated clockwise (F2 direction), and the small protrusion 39 provided at the rear end of the locking members 37A, 37B is locked by the lock formed on the control plate portion 34a. The engaging members 37A and 37B are fitted into the portion 42, and are in a lightly locked state in a posture rotated clockwise (F2 direction).

When moving the movable member 10 from the facing 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 (rotating member) 24 is driven counterclockwise by the motor 29 shown in FIG. When the posture from the facing posture to the storage posture is continuously performed, the rotating body 24 reaches the state where it rotates most counterclockwise as shown in FIG. 7 from the state of FIG. 5 through the state of FIG. The motor 29 stops.

In the process of FIGS. 5, 6 and 7, the rotating arm 24b of the rotating body 24, the sliding pin 26 fixed to the rotating arm 24, and the guide slot 23e formed in the reciprocating member 23 are constituted. The reciprocating member 2
3 is reciprocated. FIG. 6 shows the position where the reciprocating member 23 projects most forward (in the Z1 direction).
0 is the posture from FIG. 8 (A) to FIG. 9 (A). Further, when the rotating body 24 rotates from the posture shown in FIGS. 6 to 7 and the reciprocating member 23 is retracted rearward, the movable member 10 is moved from the state shown in FIG. 9A to the storage state shown in FIG. Leading to a posture.

First, in the first step in which the reciprocating member 23 projects in the Z1 direction from the facing postures shown in FIGS. 5 and 8A, the reciprocating member 23 linearly advances in the Z1 direction.
Also, a control pin 32 provided on the posture switching arm 31
Is a control plate portion 3 that constitutes the distribution means 22A and 22B.
4a linearly advances in the Z1 direction in the facing posture guide portion 35a. Therefore, the movable member 10 advances in the Z1 direction in parallel without inclining until reaching the position shown in FIG. 8B.

In FIG. 8B, the control pin 32 reaches the front end of the facing posture guide 35a, and the control pin 32 cannot move forward in the Z1 direction any more. Therefore, when the reciprocating member 23 further advances in the Z1 direction, the first support pin 12 supporting the movable member 10 advances, and the second support pin 1
3 cannot move forward any more, so the reciprocating member 23
With the advance, the upper end (the end on the second side) of the movable member 10 rotates toward the lower side (the 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 member 23. The control pin 32 is located in the vertical guide portion 35c of the distribution path 35 of the control plate portion 34a. 8 (C) to FIG. 9 (A), the reciprocating member 2
9A, the control pin 32 is located at the front end of the storage attitude guide portion 35b of the control plate portion 34a because the control pin 32 descends along the downwardly inclined guide portion 33c by the advance of 3. Therefore, in a state where the reciprocating 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.

Here, in the reciprocating member 23, FIG.
The biasing force of the tension coil spring 30 acts rearwardly at a position on the lower side of FIG. As a result, during the transition from FIG. 8A to FIG. 9A, the reciprocating member 23 is slightly rotated so that the lower side in FIG. 5 and FIG. To move forward. Therefore, when reaching FIG. 9 (A), the control pin 32 is first guided by the descending inclination guide part 33c in the distributing means 22B located in the upper part of FIG. 6, and the storage posture guide part 35b of the control plate part 34a is moved. At the front end, in the other distributing means 22A, the forward movement of the downward inclined guide portion 33c is delayed, and the control pin 32 reaches the front end of the storage posture guide portion 35b late.

However, as shown in FIG. 6 (B), immediately before the reciprocating member 23 moves forward most, the sliding pin 26 slides on the inclined portion 23h1 in the elongated guide hole 23e and rides on the convex portion 23h. As a result, a forward pressing force acts on the reciprocating member 23. Therefore, the reciprocating member 23 is corrected so as to rotate clockwise around the distribution unit 22B. That is, the reciprocating member 23 is pushed forward on the side where the biasing force biased by the tension coil spring 30 is applied.

Further, the sliding pin 2 which rotates counterclockwise
6 moves up and down the inclined portion 23h1, the reciprocating member 2
Since the couple M acts on 3, the reciprocating member 23 is immediately corrected.

Thus, when the reciprocating member 23 has moved to the front, the control pins 32 in both the left and right sorting means 22A and 22B as shown in FIG.
Is guided by the descending inclination guide 33c and is located together with the front end of the storage posture guide 35b. for that reason,
During the subsequent operation, one control pin 32 does not get caught on the vertical guide portion 43a.

When the reciprocating 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.

9 (A) to 9 (B), 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 slides on the second sliding portion 43c on the lower side of the hook members 37A and 37B. Therefore, the locking members 37A and 37B are rotated in the counterclockwise direction (F1 direction), and the small protrusion 39 provided at the rear ends of the locking members 37A and 37B is disengaged from the lock portion 42 of the control plate 34a. The arc guide 41 is entered. Therefore, the light locks of the hook members 37A and 37B are released, and the hook members 37A and 37B can rotate around the support hole 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.

In the storage position shown in FIG. 9B, the regulating shafts 15 provided on both side surfaces of the movable member 10
The rattle prevention protrusion 34d shown in FIG. 3 and the rattle prevention protrusion 34d shown in FIG. 4 enter the lower side, and the regulating shafts 15, 15 are regulated and restrained from above. Therefore, it is possible to prevent the movable member 10 from rattling up and down.

In the above description, the motor 29 is stopped by detecting that the rotating body 24 has reached the predetermined rotational position, or by detecting that the reciprocating 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.

At this time, since the reciprocating member 23 is pulled backward by the tension coil spring 30, the gap between the connecting portions of the members is absorbed by the urging force of the tension coil spring 30. When operating the operation member, the movable member 10 does not rattle.

In FIG. 8C, the panel front surface 6 appears at a position adjacent to the upper end 10c of the movable member 10 that stops 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 facing posture, the lower end 10b of the movable member 10 is pushed in the storage posture of FIGS. It is operated or a switch provided on the front panel 6 is operated.

The motor 29 is started by these operations,
The rotating body 24 starts rotating clockwise. When the rotating body 24 rotates to the position shown in FIG. 6, the reciprocating member 23 moves forward (Z1 direction) most. During this time, as shown in FIGS. 9B to 10A, the control pin 32 advances in the Z1 direction in the storage posture guide 35b of the control plate 34a. When the control pin 32 moves forward, it hits the second sliding portion 43c of the locking members 37A, 37B, so that the locking members 37A, 37B once rotate clockwise (F2 direction). However, this rotation range is limited by the locking member 37.
The small projections 39A and 37B are within the range in which the small projections 39 move in the arc guide 41 in the control plate 34a. Therefore, FIG.
As shown in (A), the control pin 32 is
5b, and the control pin 32 is moved to the locking member 37.
When the locking members 37A and 37B are disengaged from the locking members 37A and 37B, the locking members 37A and 37B are rotated counterclockwise (F1 direction) by the torsion spring 38, and the locking portions 43 at the front ends of the locking members 37A and 37B.
a closes the front end of the storage posture guide 35b. That is, the locking members 37A and 37B are in the restricted posture.

At this time, the reciprocating member 23 also
Since the rearward biasing force of the tension coil spring 30 is acting at the one-sided lower position in FIGS. 5 and 6, the reciprocating member 23 is not mechanically moved until it reaches FIG. Due to the rattling, the vehicle advances in a slightly rotated posture such that the lower side in FIGS. 5 and 6 faces rearward. Therefore,
In the distributing means 22B located in the upper part of FIG. 6, the control pin 32 reaches the front end of the storage attitude guiding portion 35b first, and the locking member 37B rotates downward. 32 is the storage posture guide 3
5b is slow to reach the front end.

Also in this case, as shown in FIG. 6 (B), immediately before the reciprocating member 23 moves forward most, the sliding pin 26 slides on the inclined surface 23h2 in the guide elongated hole 23e to project the convex portion 23.
By riding on h, a forward pressing force acts on the reciprocating member 23. Therefore, the reciprocating member 23 is corrected so as to rotate clockwise around the distribution unit 22B.

Therefore, when the reciprocating member 23 moves to the foremost position, the control pins 32 in both the left and right distribution means 22A and 22B as shown in FIG.
Are located together at the front end of the storage posture guide 35b, and the locking members 37A, 37
The control pin 32 is hooked on the hooking portion 43a of B.

The distance L1 from the center of rotation of the hook member 37A shown in FIG. 3 to the hook 43a is the distance L2 from the center of rotation of the hook member 37B shown in FIG. 4 to the hook 43a.
It is shorter than. Therefore, the hook point between the control pin 32 and the hook portion 43a when reaching the state shown in FIG.
This means that the distribution unit 22A is located on the rear side of the apparatus with respect to the distribution unit 22B.

Therefore, the tension coil spring 30
Even if the reciprocating member 23 moves forward by tilting due to the biasing force of the above, even if the advancement of the control pin 31 is delayed on the side of the distribution means 22A, the locking member 37A having the short distance L1 becomes the other locking member 37B. 10 (A).
As shown in (5), a state is reached in which the control pin 32 is hooked on the hook 43a. Also in this case, in both the distribution unit 22A and the distribution unit 22B, the locked state shown in FIG. 10A can be reliably set.

Therefore, at the time of the subsequent operation, the one control pin 32 does not return to the back of the storage posture guide portion 35b.

When the rotating body 24 further rotates clockwise from the state shown in FIG. 6, the reciprocating member 23 moves backward (Z2 direction).
The control pin 32 moves at this time, as shown in FIG.
A return to the storage guide path 35b is prevented by the hooks 43a of A and 37B. Therefore, the control pin 32
It is lifted by the downwardly inclined guide portion 33c formed on the reciprocating member 23 that moves rearward, and moves to the vertical guide portion 35c of the distribution path 35 provided on the control plate portion 34a (see FIG. 10B). Therefore, when the reciprocating member 23 moves backward, the linear guide portion 33a of the reciprocating member 23 slides on the control pin 32.

When the reciprocating member 23 moves backward, the control pin 32 is held in the vertical guide portion 35c, and the first support pin 12, which is the connection point between the reciprocating member 23 and the movable member 10, moves rearward. Therefore, the upper end (the end on the second side) 10c of the movable member 10 is lifted upward. Therefore, as shown in FIG. 10B, the movable member 10 is tilted and rotates counterclockwise. However, as shown in FIG. Guide 3
3b lifts the control pin 32, and the control pin 32
Moves to a height that allows the user to enter the facing posture guide 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 member 23 further retreats, as shown in FIGS. 11A to 11B, the control pin 3
2 moves rearward in the facing posture guide portion 35a of the control plate portion 34a, and the movable member 10 assumes the facing posture of covering the panel front surface 6. 11B, the control pin 32 enters the groove 44 of the hook members 37A and 37B and strikes the first sliding portion 43b. The control pin 32 is the facing posture guiding unit 35
a, the hooking members 37A and 37B are rotated clockwise (F2 direction), and the small projections 39 come out of the arc guide 41 and are fitted to the locks 42, and 37A and 37B enter the lightly locked state. At this time, the locking members 37A and 37B are in the regulation release posture, and the locking portions 43 are provided.
(a) opens the storage posture guide 35b.

As described above, the locking members 37A and 37B are rotatable within the range of the arc guide portion 41, and are urged in the counterclockwise direction (F1 direction) by the torsion spring 38, and furthermore, clockwise. When rotated, it is lightly locked by the lock portion 42. Since the locking members 37A and 37B are held in the restriction release posture by the light lock,
8A to 9A, the control pins 32
Can enter the storage attitude guide portion 35b of the distribution path 35 of the control plate portion 34a. Further, during the period from FIG. 9B to FIG. 10B, the control pin 32 is regulated by the locking portions 43a of the locking members 37A and 37B which are rotated counterclockwise and are in the restricting posture. , The control pin 32 can be prevented from returning to the inside of the storage posture guiding portion 35b, and the reciprocating member 2 can be prevented.
By moving back 3, the movable member 10 can be raised.

Next, as shown in FIG. 2, a hidden switch 9 is provided in the housing 2 inside the panel front surface 6. This hidden switch 9 is in a state where the operation of the movable member 10 cannot be controlled due to runaway of the control circuit or the like,
This is for returning the control circuit to the initial state when the operation is locked. Alternatively, it is used for correcting and discharging control when a disk or other recording medium loaded in the housing 2 is not discharged from the insertion / discharge port 8.

A small hole 6a for operating the hidden switch 9 is formed through the panel front surface 6. As shown in FIG. 2, in a state where the movable member 10 is housed in the housing 1, the hidden switch 9 can be operated by inserting a linear tool or the like from the small hole 6 a.

As shown in FIG. 1, a small hole 10f is also formed on the control surface 10a of the movable member 10, and as shown in FIG. 1, the movable member 10 is installed on the panel front surface 6 in a vertical posture. Sometimes, the small hole 10f and the small hole 6a
The hidden switch 9 can be operated by a linear tool or the like.

Therefore, in both the state shown in FIG. 1 and the state shown in FIG. 2, the control circuit can be initialized. When the movable member 10 also has an opening for inserting a recording medium such as a disk, the hidden switch 9 can be operated to eject the disk in both the state of FIG. 1 and the state of FIG. it can.

The hidden switch 9 and the small holes 6a, 1
The invention relating to 0f is not limited to the above embodiment, and can be used in any mechanism in which the movable member 10 covers the panel front surface and the movable member 10 does not cover the panel front surface. For example, the present invention can be implemented even when the movable member 10 is in an obliquely upward position in front of the panel front surface 6 and the small hole 6a appears at this time.

[0104]

As described above, according to the present invention, rattling can be prevented when the movable member is in each posture. Further, an elastic member is provided for the backlash, and even if a biasing force is applied to the reciprocating member by the elastic member, malfunction does not occur due to the biasing force.
