Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is attached to a thin data processing device such as a notebook type word processor or a personal computer having an opening / closing lid provided with a display on the inner surface thereof, and supports opening / closing operation of the opening / closing lid. The present invention relates to a keyboard device capable of changing the height of a key top between an operating position and a non-operating position, and particularly, only when the opening / closing lid is rotated within a predetermined angle range from its closed position. By interlocking the opening / closing operation and the operation of changing the height of the key top, by disconnecting the opening / closing operation of the opening / closing lid and the operation of changing the height of the key top in the range where the opening / closing lid is opened by a predetermined angle or more. After opening the lid from the closed position by a certain angle and changing the height of the keytop to the operating position, the height of the keytop may change even when the angle of the lid is finely adjusted. It relates keyboard device capable of adjusting freely the easily visible position display display provided on the inner surface of without lid being.

2. Description of the Related Art Notebook type word processors and the like have been remarkably popularized in recent years because they have excellent portability that they can be carried and operated anywhere, and in order to further improve portability, such word processors are used. Various proposals have been made in order to make the keyboard device attached to the etc. thinner.

For example, the applicant of the present application pays attention to the height of the key top when it is carried, and in the specification and drawings of Japanese Patent Application No. 6-190991 and the like, a guide support member for guiding and supporting the vertical movement of the key top. A switching member that elastically holds the circuit board is fixed on the circuit board, and the circuit board can be slid between the holder member that supports the guide support member and the support member that supports the circuit board. We proposed a key switch device that can lock the height of the key top to the operating position and to the non-operating position lower than the operating position when carrying.

However, in the key switch device described in the specification and the drawing of the above-mentioned Japanese Patent Application No. 6-190991, when the height of the key top is locked to the operating position or the non-operating position, it is fixed on the circuit board. It is necessary to perform the manual operation of the operated operation knob. The manual operation of the operation knob is complicated because it needs to be performed before and after the operation of the key switch device, and in some cases, it is sufficiently possible to forget the manual operation.

Regarding this point, JP-A-5-298000
The publication discloses a keyboard device in which the operation of changing the height of a keytop is linked with the opening and closing of a lid of a portable laptop personal computer or the like. The mechanism of such a keyboard device is such that a stud attached to a leaf spring sheet that elastically holds a key top is forcibly brought into contact with the outer peripheral surface of an eccentric cam attached to a rotation shaft of the lid by a spring, and the lid is opened and closed. By rotating the eccentric cam through the rotary shaft to make the leaf spring sheet slidable, the height of the key top elastically held by the leaf spring sheet is changed. That is, the operator can freely change the height of the key top of the keyboard device by appropriately adjusting the rotation amount of the lid.

[0006]

In such a keyboard device, since the operation for changing the height of the key top is performed in conjunction with the opening / closing operation of the opening / closing lid, the number of independent manual operations (operations by the operator) increases separately. There is no.

However, in this slide mechanism, the operation of changing the height of the key top is interlocked over the entire opening / closing range of the opening / closing lid. Therefore, if the angle of the opening / closing lid is different, the key top is interlocked with that angle. The height will also change.

On the other hand, in a notebook type word processor or the like which originally has a display on the inner surface of the opening / closing lid, the operator can normally recognize the contents of the display display screen with respect to the angle of the opening / closing lid (that is, the screen of the display display). Must be able to adjust freely. Generally, the content display in a notebook type word processor or the like is performed by a liquid crystal display fixed to the inner surface of the opening / closing lid, and its viewing angle is narrower than that of a CRT display device. Furthermore, the angle of the opening / closing lid that allows the operator to normally recognize the contents of the display screen depends on the eye height of the operator as well as the performance of the liquid crystal display. There is a lid angle.

There are also cases where the operator cannot normally recognize the display contents due to the reflection of external light (for example, room light or sunlight) from the screen. There is, as it were, a viewing angle caused by external light, and this viewing angle also depends on the angle of the opening / closing lid, the eye height of the operator, etc. There is a lid angle. In addition, portable word processors with excellent notebook type are often operated in different places,
As a result, the incident angle of external light changes in many cases, and the preferable angle of the opening / closing lid often changes.

Taking the above circumstances into consideration, the above-mentioned Japanese Patent Laid-Open No. 5-2
In the keyboard device described in Japanese Patent No. 98000, the height of the key top changes when the angle of the opening / closing lid is freely adjusted so that the operator can normally recognize the contents of the display screen, and as a result, the key top If the input operability cannot be secured stably, and vice versa, the operator sets the angle of the open / close lid so that the input operability of the keytop can be secured stably. However, there is a problem that the contents of the display screen cannot be recognized normally.

The present invention has been made to solve the above-mentioned problems in the prior art. The opening / closing operation of the opening / closing lid and the key are performed only while the opening / closing lid is rotated within a predetermined angle range from its closed position. The top / bottom lid can be opened / closed by interlocking with the top / bottom height changing operation and disconnecting the opening / closing lid opening / closing operation and the keytop height changing operation in the range in which the top / bottom lid is opened by a predetermined angle or more. After the keytop height is changed from the closed position to the operating position and the keytop height is changed to the operating position, the keytop height is not changed even when the opening / closing lid angle is finely adjusted. It is an object of the present invention to provide a keyboard device capable of stably securing the property and freely adjusting the display provided on the inner surface of the opening / closing lid to a position where it is easy to see.

That is, the holder member 4 and the support plate 7 are formed by a predetermined clearance (set to be larger than the thickness of the circuit board 6) between them, and are "crimped" or screwed at a plurality of locations. The circuit boards 6 are coupled to each other, and as a result, the circuit board 6 can slide on the support plate 7 via the clearance formed between the holder member 4 and the support plate 7.

As shown in FIG. 2, the rubber spring 5 is fixed on the circuit board 6 at a lower position corresponding to a portion where the first link member 10 and the second link member 11 are axially supported with respect to each other. ing. The rubber spring 5 is formed of an elastic rubber material such as silicon rubber or EPDM, and has a conical dome portion 5A, an edge portion 5B formed around the dome portion 5A, and a portion 2B extending from the edge portion 5B. It is composed of one stopper portion 5C (see FIG. 8). The movable electrode 25 made of conductive rubber is fixed to the inner upper wall of the dome portion 5A, and the first electrode is attached to the top of the dome portion 5A.
The base 12 of the link member 10 is placed. This allows
The guide member 3 including the first link member 10 and the second link member 11 is elastically held via the dome portion 5A of the rubber spring 5.

Here, the rubber spring 5 is the circuit board 6
Since it is fixed on the circuit board 6, the circuit board 6 slides along with the circuit board 6 according to the sliding operation of the circuit board 6.
Therefore, as shown in FIG. 2, the position where the rubber spring 5 supports the guide member 3 (hereinafter, referred to as “second position”).
When it is slid, the height of the key top 2 is at the operation position, and as shown in FIG. 9 described later, the position where the rubber spring 5 is disengaged from the guide member 3 (hereinafter referred to as “first position”). ), The height of the key top 2 is changed to the non-operation position. The sliding operation of the circuit board 6 is performed by the opening / closing lid 6 of the keyboard device 61.
The opening / closing lid 6 is performed in response to the opening / closing operation of 2.

A pair of fixed electrodes 26 are formed on the circuit board 6 corresponding to the movable electrodes 25 in the dome portion 5A of the dome portion 5A. The fixed electrodes 26 are movable when the key top 2 is pressed, as will be described later. The switching operation is performed by being short-circuited to each other via the. Note that, as shown in FIG. 2, the fixed electrode 26 is formed so as to be shifted slightly to the left of the vertical line L with respect to the movable electrode 25. This is because when the key top 2 is pressed down, the sliding pin 14 of the first link member 10 and the sliding pin 19 of the second link member 11 respectively have the first locking portion 8 and the third locking portion 23, respectively. Since the movable electrode 25 of the rubber spring 5 also shifts slightly to the left in FIG. This is because the fixed electrode 26 is short-circuited at some part.

Subsequently, the switching operation of the key switch 1 configured as described above will be described with reference to FIGS.
It will be explained based on. FIG. 5 is a side cross-sectional view of the key switch 1 showing a state where the key top is pressed during key operation.

When the key top 2 is pushed down from the state shown in FIG. 2, each sliding pin 14 of the first link member 10 in the guide member 3 is slid to the left inside the first locking portion 8 and at the same time. The locking pin 15 is rotated counterclockwise in the fourth locking portion 24. At the same time, the locking shaft 20 of the second link member 11 of the guide member 3 is rotated clockwise in the second locking portion 9, and the sliding pin 19 is leftward in the third locking portion 23. Be slid on. At this time, the key top 2 is
The link member 10 and the second link member 11 cooperate to move the key top 2 downward while maintaining the horizontal state regardless of the pressed position.

With the downward movement of the key top 2, the first
The base 12 of the link member 10 gradually becomes the rubber spring 5
The dome portion 5A is pushed, and when the pushing force exceeds a certain limit, the dome portion 5A buckles with a click feeling. Due to the buckling of the rubber spring 5, the movable electrode 25 fixed to the inner upper wall of the dome portion 5A short-circuits the fixed electrodes 26 formed on the circuit board 6 as shown in FIG. Thus, the on-switching operation is performed.

When the key top 2 is released,
The base portion 12 of the first link member 10 is urged upward by the elastic force (returning force) of the rubber spring 5. At this time, each sliding pin 14 of the first link member 10 is slid to the right in the first locking portion 8 and the locking pin 15 is rotated clockwise in the fourth locking portion 24. It At the same time, the locking shaft 20 of the second link member 11 of the guide member 3 is rotated counterclockwise in the second locking portion 9, and the sliding pin 19 is moved in the third locking portion 23. It is slid to the right. Along with this, the dome portion 5A of the rubber spring 5 gradually returns to the original state, and the movable electrode 25 is separated from each fixed electrode 26 in this process. At this point, it turns off,
The off-switching operation is performed. Then, the key top 2 returns to the original non-depressed state shown in FIG. 2 via the elastic force of the rubber spring 5. At this time, key top 2
Is moved upward while maintaining the horizontal state by the cooperative action of each of the first link member 10 and the second link member 11 as in the case of pressing.

Subsequently, a slide interlocking mechanism for sliding the circuit board 6 of the key switch 1 in response to the opening / closing operation of the opening / closing lid 62 and a spring for urging the circuit board 6 in a predetermined direction will be described with reference to FIGS. It will be described based on 7. 6 is a side sectional view of the word interlock 60 showing the state of the slide switch interlocking mechanism and the key switch 1 when the opening / closing lid 62 is completely closed (closed position), and FIG. 7 is the slide interlocking mechanism of the key switch 1 side. It is a disassembled perspective view of a principal part.

As shown in FIGS. 1 and 6, the slide interlocking mechanism 30 has a toothless gear 31 having gear teeth 31A fixed to the support shaft 64, and rack teeth 32A fixed to the circuit board 6. The rack 32 is basically configured.

As shown in FIGS. 1 and 6, the tooth-chipped gear 31 is coaxially fixed to a support shaft 64 which pivotally supports an openable / closable lid 62 via a hinge 63. Therefore, similarly to the support shaft 64, the tooth-chipped gear 31 corresponds to the counterclockwise direction when the opening / closing lid 62 is opened and the clockwise direction when the opening / closing lid 62 is closed in FIG. And rotate. Further, the gear teeth 31A are not provided on the entire circumference, and are within a predetermined angle A of the opening / closing lid 62 where the operator cannot perform key operation, that is, immediately after opening / closing the opening / closing lid 62 (see FIG. 10).

The support plate 7 has a sliding hole 3 through which the guide pin 35 slides.
7 is provided and guided by this, the circuit board 6 can slide along with the rack 32. Further, the rack teeth 32A of the rack 32 are within the angle of the opening / closing lid 62 that cannot be operated by the operator, that is, within a predetermined angle A (see FIG. 10) immediately after the opening / closing lid 62 is opened or closed. It is provided so as to mesh with the gear teeth 31A of the tooth gear 31. Here, the reinforcing plate 38 is provided so as to extend from one end to the other end in the longitudinal direction of the keyboard device. Thereby, the entire circuit board 6 can be stably slid.

Further, as shown in FIG. 6, both ends of the spring 33 are fixed inside the main body of the rack 32 and the keyboard device 61. Therefore, since the elastic force of the spring 33 always acts on the circuit board 6 via the rack 32 in the right direction in the figure,

FIG. 10 shows the slide interlocking mechanism 30 and the key switch 1 when the opening / closing lid 62 is at a predetermined angle (during opening). FIG. 11 is a side sectional view showing the state of the word processor 60, and FIG. 11 is a schematic view showing the relationship between the holder member 4 and the rubber spring 5 at the operation position of the key top 2 when the opening / closing lid 62 is at a predetermined angle (during the opening). 13 and 14 are diagrams showing the relationship between the angle of the opening / closing lid 62 and the height of the key top 2.

When the opening / closing lid 62 is in the closed position, the rubber spring 5 is held at the position shown in FIG. 8 (the left end side position in FIG. 8) and the base 12 of the first link member 10 is held.
Is completely removed from the dome portion 5A of the rubber spring 5. That is, the rubber spring 5 is present at the first position which is out of the guide member 3. Therefore, each of the first link member 10 and the second link member 11 is completely folded and placed on the circuit board 6, and the height of the key top 2 does not receive any elastic force from the rubber spring 5. Therefore, it is in the lowest non-operation position as shown in FIG.

The operator closes the open / close lid 62 at the closed position (see FIG. 6).
A), the hinge 63
The support shaft 64 rotates counterclockwise via (see FIG. 10). Along with this, the toothless gear 31 fixed to the support shaft 64 also rotates counterclockwise. Gear tooth 3 of toothless gear 31
1A and the rack teeth 32A of the rack 32 mesh with each other at the position where the opening / closing lid 62 is closed, so that the guides provided on the reinforcing plate 38 (rack 32) along with the operation of opening the opening / closing lid 62 by the operator. The pin is guided by the sliding hole 37, and a force for sliding the rack 32 to the right in the drawing acts. Therefore, the circuit board 6 to which the rack 32 is fixed is
Along with the operation of opening the opening / closing lid 62 by the operator, it is slid to the right in the drawing.

Further, the operator opens the opening / closing lid 62,
The angle of the opening / closing lid 62 is the value of A (a′−a ′ in FIG. 10).
Position), the toothless gear 31 and the rack 32 no longer mesh with each other. Then, at the same time that the tooth-chipped gear 31 and the rack 32 do not mesh with each other, the guide pin 35 of the reinforcing plate 38 provided with the rack 32 comes into contact with the end of the sliding hole 37, so that the circuit board 6 to which the rack 32 is fixed is Stop the slide operation. Therefore, even if the operator continues the operation of opening the opening / closing lid 62 beyond the value of A, the rack 32 does not slide to the right in the figure due to this operation. Rack 3
The elastic force of the spring 33 fixed to 2 is set by the operator while the tooth-missing gear 31 and the rack 32 are engaged with each other.
Since it assists in opening 2, the operator can lightly open the opening / closing lid 62. And the toothless gear 31 and the rack 3
When the two do not mesh with each other, the reinforcing plate 38 (rack 32) is always urged in the right direction in the drawing, so the circuit board 6 does not move in the left direction in the drawing.

In the key switch 1, the circuit board 6 described above is used.
Corresponding to the sliding movement of, the rubber spring 5 disposed on the circuit board 6 moves in the D direction as shown in FIG. That is, it slides from the first position shown in FIG. 8 to the second position supporting the guide member 3 shown in FIG. Therefore, as shown in FIG. 9, the guide member 3 that has been folded when the open / close lid 62 is in the closed position (during carrying) gradually opens to the state of the key operation shown in FIG. . Along with this, the height of the key top 2 is also gradually increased, and is changed from the non-operating position when carrying to the operating position when operating the key.

As described above, when the rubber spring 5 is held at the second position by the circuit board 6 being biased by the spring 33, the height of the key top 2 at the operation position during key operation is accordingly accompanied. Held in. That is, as shown in FIG. 13, the angle of the opening / closing lid 62 is near A (a in FIG. 10).
At the'-a 'position), the change of the height of the key top 2 is completed.

Therefore, while the slide interlocking mechanism 30 and the spring 33 open the opening / closing lid 62 within the range from the closed position to the predetermined angle A, the operator operates the opening / closing lid 62 and the key top 2 is opened. At the same time as the height changing operation is linked, the height changing operation of the key top 2 can be completed when the angle of the opening / closing lid 62 is near A.

Next, when the operator uses the word processor 60 by further opening the opening / closing lid 62, the function of the slide interlocking mechanism 30 and the spring 33 while the opening / closing lid 62 is rotated from the angle A to the open position. This will be described with reference to FIGS. 6, 10, 12, and 13. FIG.
2 is a word processor 6 showing the state of the slide interlocking mechanism 30 and the key switch 1 when the opening / closing lid 62 is completely opened.
It is a side sectional view of 0.

As described above, the operator opens / closes the lid 62.
When the opening of the open / close lid 62 starts from the closed position,
Below the value (see FIG. 10), the gear teeth 31A of the tooth-chipped gear 31 and the rack teeth 32A of the rack 32 are in mesh with each other (see FIG. 6), so that when the operator opens the opening / closing lid 62, The height of the key top 2 is changed.
However, when the operator further opens the opening / closing lid 62 and the angle of the opening / closing lid 62 exceeds the value of A (position a'-a 'in FIG. 10), the tooth-chipped gear 31 and the rack 32 do not mesh with each other and the circuit board 6 is urged by the elastic force of the spring 33. As a result, when the rubber spring 5 is held at the second position, the height of the key top 2 is held at the height of the operating position when the key is operated. That is, as shown in FIG. 13, the angle of the opening / closing lid 62 is A (position a'-a 'in FIG. 10).
In the above, the height of the key top 2 is continuously held at the operation position at the time of key operation, regardless of the operation of the operator to open the opening / closing lid 62.

Therefore, the angle of the opening / closing lid 62 is the value of A (see FIG. 1).
Since the circuit board 6 does not slide above the a'-a 'position at 0), as shown in FIG.
The operability of the key top 2 can be stably ensured without the height of the key top 2 being held at the operation position during key operation and being continuously changed.

At the same time, when the angle of the opening / closing lid 62 is equal to or larger than the value A (position a'-a 'in FIG. 10), the tooth-chipped gear 31 and the rack 32 do not mesh with each other. The height of the key top 2 does not fluctuate due to the opening operation of 62, and the operator can freely adjust the liquid crystal display 34 fixed to the opening / closing lid 62 to a position where it is easy to see.

Further, when the operator rotates the open / close lid 62 in the clockwise direction to close it, while the open / close lid 62 is closed from the open position to the closed position, the slide interlocking mechanism 30 is provided.
The functions of the spring 33 and the spring 33 are shown in FIGS. 6, 8, 9, and 1.
0, FIG. 11, and FIG. 13 will be described.

When the operator starts closing the opening / closing lid 62 from the open position, as shown in FIG. 10, when the angle of the opening / closing lid 62 is equal to or larger than the value A, the tooth-chipped gear 31 and the rack 32 are not meshed with each other. The opening / closing lid 62 is closed without changing the height of the top 2. However, when the operator further closes the opening / closing lid 62 and the angle of the opening / closing lid 62 reaches the value A, the tooth-chipped gear 31 and the rack 32 come into mesh with each other. Therefore, when the angle of the opening / closing lid 62 becomes equal to or smaller than the value A, the elastic force of the spring 33 against the circuit board 6 is always present. Key top 2 as shown in
The height of the is changed from the operating position when the key is operated to the non-operating position when carrying.

In the key switch 1, the rubber spring 5 arranged on the circuit board 6 moves in the C direction in response to the above-described sliding movement of the circuit board 6 in the opposite direction. That is, from the second position shown in FIG.
It slides to the first position shown in. Therefore, the guide member 3 gradually shifts from the state shown in FIG. 2 when the key is operated to the folded state shown in FIG. 9 when it is carried. Along with this, the height of the key top 2 also gradually decreases, and is changed from the operating position when the key is operated to the non-operating position when carrying the key.

As for the height of the key top 2, when the angle of the opening / closing lid 62 is in the vicinity of the value A (position a'-a 'in FIG. 10),
When the circuit board 6 is slid by the slide interlocking mechanism 30 and the rubber spring 5 is held at the first position,
Along with this, the key top 2 is held at the height of the non-operating position when being carried. That is, as shown in FIG.
At the closed position (position aa in FIG. 6), the change of the height of the key top 2 is completed.

Therefore, while the opening / closing lid 62 is closed within the range from the predetermined angle A to the closing position by the slide interlocking mechanism 30 and the spring 33, the operator performs the closing operation of the opening / closing lid 62 and the operation of the key top 2. At the same time as the height changing operation is linked, the opening / closing lid 62 can complete the height changing operation of the key top 2 at the closed position.

Further, when the open / close lid 62 is in the closed position (when carrying), the toothless gear 31 and the rack 32 are in mesh with each other, and at the same time, the key switch 1 is formed in the rubber spring 5 as shown in FIG. Each stopper 5C
Is in a state of being locked in each locking groove M formed in the second link member 11. Therefore, the circuit board 6 does not slide when being carried, and the key top 2 and the opening / closing lid 62 do not interfere with each other when the opening / closing lid 62 is closed.

As described in detail above, in the keyboard device 61 according to the present embodiment, the toothless gear 31 having the gear teeth 31A fixed to the support shaft 64 that rotates in conjunction with the opening / closing of the opening / closing lid 62, and , A rack 32 having rack teeth 32A fixed on the circuit board 6 and capable of meshing with the gear teeth 31A
And the gear teeth 31A and the rack teeth 32A mesh with each other only between the closed position of the opening / closing lid 62 and the position opened by a predetermined angle (angle A). , The opening / closing lid 62 has a predetermined angle (angle A)
In the above open range, the gear teeth 31A and the rack teeth 32A are prevented from meshing with each other so that the opening / closing lid 6
Since the interlocking between the opening / closing operation of No. 2 and the operation of changing the height of the key top 2 is cut off, when the opening position of the opening / closing lid 62 is between the closing position and the predetermined angle (angle A). The first position where the rubber spring 5 is disengaged from the guide member 3 and the key top 2 is held in the non-operating position based on the fact that the circuit board 6 is slid in conjunction with the opening / closing operation of the opening / closing lid 62 and the rubber spring. 5 supports the guide member 3 and can hold the key top 2 in the second position where it is held in the operating position, and in the range where the opening / closing lid 62 is opened at a predetermined angle (angle A) or more. Can be freely adjusted to a position where the liquid crystal display 34 of the opening / closing lid 62 is easy to see without changing the height of the key top 2 while maintaining the operation position.

In the slide interlocking mechanism 30, between the inner wall of the main body of the keyboard device 61 and the rack 32,
Since the spring 33 for urging the circuit board 6 is arranged via the rack 32, the key top 2 is moved to the operation position (second position) in conjunction with the opening / closing operation of the opening / closing lid 62 as described above. At this point, the gear teeth 31A of the toothless gear 31 and the rack 3
Even when the meshing with the second rack tooth 32A is released, the rubber spring 5 can be held at the second position via the biasing force of the spring 33 and the key top 2 can be stably held at the operating position. . Thereby, the operability of the key top 2 can be stably ensured.

Next, a keyboard device according to a second embodiment of the present invention will be described with reference to FIG. As described above, in the first embodiment, in order to slide the circuit board 6 following the opening / closing of the opening / closing lid 62, the reinforcing plate 38 has a movable width between the reinforcing plate 38 and the holder member 4. A gap S of constant width (Fig. 7) is required. However, when the circuit board 6 is slid to move the switching member 5 from the first position to the second position, the reinforcing plate 3 of the holder member 4 is moved.
The edge portion facing 8 becomes a resistance, and the circuit board 6 may rise from the space between the reinforcing plate 38 and the holder member 4 and stick out, and the circuit board 6 may undulate. When the circuit board 6 is wavy,
Not only will it hinder the switching between the operating state and the non-operating state of the key switch 1, but also the circuit board 6 will be bent, and if it is once bent, the circuit board 6 will remain bent. . In view of the above, in the second embodiment, the circuit board 6 is prevented from rising and corrugating from the gap between the holder member 4 and the reinforcing plate 38, and the circuit board 6 is normally slid. This is a further addition to the embodiment. Note that, in FIG. 14, the same members as those of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

Similar to the first embodiment, the reinforcing plate 138.
Racks 132 that mesh with the gear teeth 31A (FIG. 6) of the tooth-chipped gear 31 (FIG. 6) are integrally formed on the upper surfaces of the two sides of the keyboard device, and extend from one end to the other end in the longitudinal direction of the keyboard device. Guide pins 35, which penetrate through the guide pin holes 36 of the circuit board 6 and extend into the sliding holes 37 of the support plate 7, are provided on the lower surface sides of the reinforcing plate 138 provided at two positions on both sides. . At the lower end of the guide pin 35, a head having a diameter larger than the width of the sliding hole 37 is provided. By the sliding contact motion between each guide pin 135 and the sliding hole 37, the reinforcing plate 1
38 is moved while maintaining a parallel state without being tilted, and it is possible to prevent the circuit board 6 from being slid while being tilted.

Reinforcing plate 138 facing the holder member 104
A plurality of concave portions 138A are formed at the edge portion of. Therefore, a convex portion 138B is formed between the adjacent concave portions 138A.
On the other hand, the holder member 1 facing the edge of the reinforcing plate 138.
A plurality of convex portions 104A are formed at positions corresponding to the plurality of concave portions 138A on the edge portion 04. The plurality of protrusions 104A of the holder member 104 will be located in the plurality of recesses 138A of the reinforcing plate 138, but the protrusions 104A
When the rubber spring 5 is in the first position, a gap is formed between the tip of the sliding hole 37 and the bottom of the recess 138A by at least the stroke length of the sliding hole 37.

With this structure, the gap between the opposing edges of the holder member 104 and the reinforcing plate 138 is interrupted by the plurality of convex portions 104A. Therefore, the reinforcing plate 138
Is moved in the direction of arrow D, the circuit board 6
Even if an attempt is made to enter this gap by the resistance of the edge portion of 04, the plurality of convex portions 104A press the upper surface of the circuit board 6,
Intrusion is suppressed. Therefore, the circuit board 6 holds down the reinforcing member 138 and the holder member 104 provided along the longitudinal direction of the keyboard and the holder member 104.
By the pressing action of each of the protrusions 104A, waviness and bending are surely prevented, and the support plate 7 can be smoothly slid while maintaining its flatness.

Next, the interlocking mechanism 230 of the keyboard device according to the third embodiment of the present invention will be described with reference to FIGS.
It will be explained based on. For convenience of explanation, FIGS.
In FIG. 0, the circuit board 6 is omitted.

A first protrusion 238A is formed on the upper surface of the reinforcing plate 238.
And a pair of second protrusions 238B are provided so as to penetrate the reinforcing plate 238. A pair of second protrusions 2
The lower portion of 38B is provided so as to be capable of reciprocating sliding in a sliding hole 37 formed in the holding plate 7. Therefore, the second protrusion 238
The lower part of B is the guide pin 35 in the above-mentioned embodiment.
Corresponding to.

The rack 32 in the above-mentioned embodiment,
Instead of 132 (FIG. 6, FIG. 14), a slide member 232
Are provided separately from the reinforcing plate 238. As shown in FIG. 16, one slide member 232 is provided on each rear side of both ends of the notebook word processor. A compression coil spring 233 is provided on the inner end side of the slide member 232.
Is connected to the reinforcing plate 238 via the spring 234.
That is, the compression coil spring 233 is wound around the first protrusion 238A of the reinforcing plate 238, and both ends of the spring 234 are locked to the upper portion of the second protrusion 238B. Both ends of the compression coil spring 233 are in contact with the wall surface of the holder member 204, and as a result, the compression coil spring 233 urges the slide member 232 to the left in FIG. This direction is the direction in which the rubber spring 5 is held in the second position. The center of the spring 234 is in contact with the inner end surface of the slide member 232, and biases the slide member 232 to the left in FIG. Therefore, the circuit board 6 is biased in the second position direction by the compression coil spring 233 and the spring 234.

A slot 232c is formed in the center of the slide member 232, and a projection 7A projecting upward from the holding plate 7 is located in the slot 232c. A cylindrical protrusion 204a protruding downward from the holder member 204 is fitted in the protrusion 7A, so that the holder member 204 is supported by the holding plate 7. Also, the cylindrical protrusion 204
Since the outer peripheral surface of a is in sliding contact with the slot 232c,
The cylindrical member 204a ensures that the slide member 232 moves in a straight line.

The outer end wall 2 is provided on the outer end side of the slide member 232.
A recess 232a defined by 32b is formed and the hinge 6
Claws 231 engageable with the wall 232b of the concave portion 232a are provided at positions corresponding to 3 (FIG. 1). The claw 231 is
It corresponds to the partly tooth-missing gear 31 of the above-described embodiment. Here, the claw 231 is the opening / closing lid 6 in FIGS. 15, 17, and 19.
2 is rotated clockwise, and when the opening / closing lid 62 is closed, it is rotated counterclockwise in response to the opening / closing operation of the opening / closing lid 62. Further, it is provided so as to be engaged with the recess 232a within an angle of the opening / closing lid 62 where the operator cannot perform key operation, that is, within a predetermined angle immediately after opening / closing the opening / closing lid 62. In other words, after the opening / closing lid 62 exceeds the predetermined angle A shown in FIG. 10, the claw 231 is configured to be separated from the wall 232b of the recess 232a.

With the above-described structure, as shown in FIGS. 15 and 16, when the opening / closing lid 62 is in the closed position, for example, when it is carried, the compression coil spring 233 and the spring 234.
Against the urging force of the inner surface 2 of the claw 231 of the recess 232a.
32b is pressed in the direction of arrow C in the figure. Therefore, the slide member 232 moves in the C direction, and the reinforcing plate 238 also moves in the C direction via the spring 234. As a result, as shown in FIG. 8, the dome portion of the rubber spring 5 moves to a position completely separated from the base portion of the first link member 10. That is, the rubber spring 5 is located at the first position, which is separated from the guide member 3. At this time, each stopper 5 formed on the rubber spring 5 is similar to the above-described embodiment.
C is in a state of being locked in the respective locking grooves M formed in the second link member 11, so that the circuit board 6 does not slide when being carried and the key top 2 is in a state in which the opening / closing lid 62 is closed. Does not interfere with the open / close lid 62.

Therefore, each of the first link member 10 and the second link member 11 is completely folded and placed on the circuit board 6, and the height of the key top 2 has no elastic force from the rubber spring 5. Since it is not received, it is in the lowest non-operating position as shown in FIG.

As shown in FIGS. 17 and 18, when the operator starts opening the opening / closing lid 62, the claw 231 also rotates clockwise. Then, the slide member 232 starts moving in the direction of the arrow D by the biasing force of the compression coil spring 233 and the spring 234 while receiving the sliding guide by the cylindrical protrusion 204a and the slot 204a. Therefore, the reinforcing plate 238 moves in the arrow D direction via the compression coil spring 233 and the spring 234. Note that the claw 231 is the recess 232a.
Of the compression coil spring 2 while engaging with the inner wall 232b of the
Since the opening / closing lid 62 is urged in the opening direction by the urging force of the spring 33 and the spring 234, the operator can lightly open the opening / closing lid 62.

As shown in FIGS. 19 and 20, when the operator further opens the opening / closing lid 62 and the opening / closing lid 62 reaches a predetermined angle A (see also FIGS. 10 and 13), the claw 23 is released.
The pointed surface of No. 1 is separated from the inner wall 232b of the recess 232a. Therefore, the slide member 232 is the compression coil spring 23.
3 and the urging force of the spring 234 further move in the D direction, and similarly, the reinforcing plate 238 further moves in the D direction and further moves the circuit board 6 in the D direction. When the lower portions of the pair of protrusions 238B abut at the ends of the pair of sliding holes 37, and the cylindrical protrusion 204a also abuts at the ends of the slots 232c, the rubber spring 5 is held in the second position. The Rukoto.

Therefore, even if the operator continues to open the open / close lid 62 beyond the value of A, the pointed surface of the claw 231 is separated from the inner wall 232b of the recess 232a, so that the claw 231 slides. It has no effect on 232. Therefore, the slide member is the compression coil spring 2
By the urging force of the spring 33 and the spring 234, the circuit board 6 remains held at the predetermined position shown in FIGS. 19 and 20, and therefore the circuit board 6 is also held at the predetermined position. Here, the key switch moves to the second position supporting the guide member 3 shown in FIG. 11 in response to the sliding movement of the circuit board 6 described above. Therefore, the folded guide member 3 is urged upward by the rubber spring 5, the position of the key top 2 is raised, and the key top 2 is changed to the operation position for key operation.

The operation of the interlocking mechanism 230 accompanying the operation of closing the opening / closing lid 62 is the reverse of the operation described above.
Description is omitted. Also in the keyboard device according to the third embodiment described in detail above, the opening / closing lid 62 has the predetermined angle A.
When the opening / closing operation is performed in a range exceeding the range, the opening / closing operation of the opening / closing lid does not have any influence on the height of the key top. Therefore, without changing the height of the key top 2, the liquid crystal display 34 of the opening / closing lid 62 can be freely adjusted to a position where it can be easily seen while maintaining the operation position.

The fourth embodiment of the key switch device according to the present invention will be described with reference to FIG. In the third embodiment, one set of interlocking mechanism 230 is provided at both ends of the word processor main body, but in the fourth embodiment, a compression coil spring 233 is added between the interlocking mechanisms 230, The urging force on the circuit board 6 is enhanced. That is, a plurality of protrusions 238A corresponding to the first protrusions 238A of the reinforcing plate 238 are provided on a plurality of reinforcing plates at regular intervals, and the respective central portions of the compression coil springs 233 are wound around and supported by the respective protrusions 238A. Spring 233
The both ends of the holder are brought into contact with the wall surface of the holder member 204. As a result, the urging force of the compression coil spring 233 is evenly transmitted to the circuit board 6, and the urging force is increased, so that the rubber spring is reliably held at the second position. In other words, since the biasing force of each compression coil spring is small, even a small compression coil spring is sufficient, which is advantageous in design.

The keyboard device according to the present invention is not limited to the above-described embodiment, but various modifications can be made within the scope of the claims. For example, in the above-described embodiment, when the key top 2 is pressed down, the movable electrode 2 fixed to the inner upper wall of the dome portion 5A of the rubber spring 5 is pressed.
5 and the fixed electrode 26 formed on the circuit board 6 are brought into contact with each other to perform the switching operation. However, a so-called membrane switch having a spacer interposed between two switching sheets is used as a holder member 4, 104, It is obvious that the same effect as that of each of the above-described embodiments can be obtained even in the case of the key switch 1 arranged on the lower surface of 204 and having the pressing portion formed on the inner upper wall of the dome portion 5A.

Further, in the second embodiment, the protrusion 1
04A is provided on the holder member 104, and the corresponding recess 1
Although 38A is formed on the reinforcing plate 138, a protrusion may be provided on the reinforcing plate and a corresponding recess may be formed on the holder member. Furthermore, the configuration for preventing the circuit board from being lifted in the second embodiment may be added to the third to fourth embodiments.

[0080]

As is apparent from the above description, according to the keyboard device of the first aspect of the present invention, only when the opening / closing lid is rotated within a predetermined angle range from its closed position. , The operation of opening / closing the opening / closing lid and the operation of changing the height of the key top are interlocked, and when the opening / closing lid is rotated within a range exceeding a predetermined angle, the opening / closing lid is rotated and the height of the key top is changed. By cutting off the interlocking with the changing operation of the key top, the operability of the key top can be stably maintained without changing the height of the key top at the operation position even when the angle of the opening / closing lid is finely adjusted. In addition, it is possible to freely adjust the display provided on the inner surface of the opening / closing lid to a position where it is easy to see.

According to the keyboard device of the second aspect, the urging means is provided in connection with the driven means, and the urging force of the urging means causes the opening / closing lid to rotate more than a predetermined opening angle. Since the switching member is held in the second position in the moved state, the key top is securely held in the operating position.

Further, according to the keyboard device of the third aspect, it is possible to surely obtain the same effect as that of the first aspect with a simple structure.

Further, according to the keyboard device of the fourth aspect, since the opening / closing lid is urged in the opening direction while the claw is engaged with the recess, the operator can lightly open the opening / closing lid. it can. Further, when the operator further opens the opening / closing lid and the opening / closing lid reaches the predetermined angle A, the claw is separated from the concave portion, so that there is no influence on the slide member.

Further, according to the keyboard device of the fifth aspect, it is possible to surely obtain the same effect as that of the fourth aspect with a simple structure.

Further, according to the keyboard device of the sixth aspect, a gap is provided between the opposing end faces of the reinforcing member and the holder member to allow the switching member to move between the first position and the second position. However, since a protrusion is formed on one of the facing end faces and a recess corresponding to the protrusion is formed on the other end face, which obstructs the linearity of the gap, when sliding the circuit board, The flexible circuit board does not enter the gap to cause waviness or rising, and the circuit board can be slid smoothly.
