Therefore it reaches the projection p ₂ within the cam groove CG, further vertical slide plate 3 and the cam groove CG formed thereto is moved upward, the projection p ₂ is pushed to the wall defining the cam groove CG, rotation It moves toward the second guide plate 12 in the direction of the axis X. As a result, the horizontal slide plate 5 and the horizontal rack HR formed on the horizontal slide plate 5 also move in the direction of the rotation axis X toward the second guide plate 12, as shown in FIGS. 5 (c) and 7 (b). As described above, the horizontal rack HR and the pinion gear Pn ₁ are engaged with each other.

When the horizontal rack HR and the pinion gear Pn ₁ are engaged with each other, a rack and pinion mechanism is formed by the pinion gear Pn ₁ and the horizontal rack HR. Therefore, in the state shown in FIG. 5C and FIG. 7B, the rotation of the gear train 6 is transmitted to the upper and lower slide plates 3 to move the upper and lower slide plates 3 upward and at the same time to the horizontal slide plate 5. Then, the horizontal slide plate 5 is moved in the direction of the rotation axis X. Here, the pitches of the upper and lower racks VR and the horizontal rack HR are the same. Therefore, the horizontal slide plate 5 vertical slide plate 3 to move at the same speed, the projection p ₂ provided on a horizontal slide plate 5 is provided at an angle of 45 ° with respect to the vertical direction in the vertical sliding plate 3 The cam groove CG moves smoothly.

FIG. 7C shows a state where the upper and lower slide plates 3, the combiner support 4, and the shaft SH are slightly moved upward from the state shown in FIGS. 5C and 7B. In this state, the projection p ₂ of the horizontal slide plate 5 is fitted in the cam groove CG of the upper and lower sliding plate 3. Even in this state, both the upper and lower racks VR and HR are engaged with the pinion gear Pn _1, and both the upper and lower slide plates 3 and the horizontal slide plate 5 are moved by the rotation of the pinion gear Pn ₁ .

In the mobile device M of the present embodiment, while the projection p ₂ of the horizontal slide plate 5 is fitted with the cam groove CG of the upper and lower sliding plate 3, the upper and lower slide plate 5 vertical rack VR and the horizontal slide Both of the horizontal racks HR of the plate 5 are engaged with the pinion gear Pn _1, and both the upper and lower slide plates 3 and the horizontal slide plate 5 are moved by the rotation of the pinion gear Pn ₁ .

  FIG. 5 shows a state in which the upper and lower slide plates 3, the combiner support 4, and the shaft SH have moved slightly upward and the horizontal slide plate 5 has moved slightly to the second guide plate 12 side from the state shown in FIG. It is shown in (d) and FIG. 7 (d).

In this state, the lower end of the upper and lower rack VR of the upper and lower slide plate 3 is located above the pinion gears Pn ₁ of the gear train 6, the pinion gear Pn ₁ is disengaged from the upper and lower rack VR. That is, the upper and lower racks VR and the pinion gears Pn _{1 to} Pn ₃ do not form a rack and pinion mechanism.

On the other hand, in this state, the protrusions p ₁ , p ₂ and p ₃ formed on the horizontal slide plate 5 are formed in the support grooves SG ₁ formed on the upper and lower slide plates 3 at intervals determined in the rotation axis X direction, It is fitted to SG ₂ and SG ₃ respectively. Thus, the upper and lower sliding plate 3, despite the engagement of the upper and lower racks VR and the gear train 6 is eliminated, the projection _p 1 ~p _3, is supported by engagement between the support groove _SG 1 to SG ₃ Therefore, downward movement is restricted.

In this state, both end portions of the shaft SH are in contact with the leaf springs fs arranged at the upper end portion 11gt of the first shaft guide groove 11g and the upper end portion 12gt of the second shaft guide groove 12g, and move upward. Is regulated. That vertical slide plate 3, the shaft SH connecting combiner support 4, and these together, the engagement between the projections _p 1 ~p ₃ horizontal slide plate 5 and the support groove _SG 1 to SG ₃ of the upper and lower sliding plate 3 The downward movement is restricted by the contact between both ends of the shaft SH and the leaf spring fs, and is held at a fixed position in the vertical direction. Further, the shaft SH is urged downward by the leaf springs fs at both ends in a state where the downward movement is restricted, so that the swinging is suppressed. This state is a state in which the upward movement of the combiner support 4 and the combiner C supported by the combiner support 4 is completed, and the state of the moving device M when the combiner C is in the unfolded state shown in FIG. Equivalent to.

Further, in the state shown in FIG. 5D, the top surface of the protrusion p ₄ formed on the first projecting portion 51 of the horizontal slide plate 5 is provided on the first guide plate 11 side of the combiner support 4. faces the side surface SS of the rib 41, the rib top surfaces of the projections p ₅ formed on the second projecting portion 52 of the horizontal slide plate 5, provided in the second guide plate 12 side of the combiner support 4 41 It faces the side surface SS.

FIG. 8 shows how this state is viewed from above. As shown in FIG. 8, the top surface of the projections p _4, p _5, among the side SS of the ribs 41 are opposed to the side surface S _R1 extending parallel to the holding plate portion 40 of the combiner support 4.

When the pinion gear Pn ₁ is further rotated from the state shown in FIG. 5D, the upper and lower racks VR are not engaged with the pinion gear Pn _{1 as} described above, and only the horizontal rack HR is engaged with the pinion gear Pn ₁ . Therefore, only the horizontal slide portion 5 moves to the second guide plate 12 side along the rotation axis X direction. At this time, the projection _p 1 ~p ₃ horizontal sliding plate 5 fitted above and below the slide plate 3 supporting groove _SG 1 to SG ₃ formed on the inside support groove _SG 1 to SG ₃ second guide plate 12 (Fig. 6 (e)). Accordingly, the downward movement of the upper and lower slide plates 3, the combiner support 4, and the shaft SH remains restricted.

Further, when the horizontal slide plate 5 moves in the direction of the rotation axis X toward the second guide plate 12, as shown in FIG. 6E, the first and second projecting portions 51, 52 of the horizontal slide plate 5. projections _p 4, _{p 5} formed, abuts against the inclined side surface _{S TR} ribs 41 of combiner support 4, slides on the inclined side surface _{S TR.} As a result, the holding plate portion 40 of the combiner support 4 is pushed in a direction away from the side plate 2 and the upper and lower slide plates 3 as indicated by an arrow A in FIG. 9, and the combiner C attached to the holding plate portion 40 is A shaft SH that is stationary in a stable state that is biased by the leaf spring fs and prevented from swinging at the upper end portion 11gt of the first shaft guide groove 11g and the upper end portion 12gt of the second shaft guide groove 12g. Rotate (tilt movement).

Thereafter, the horizontal slide plate 5 moves in the direction of the rotation axis X until the projections p _{1 to} p ₃ abut against the stop plates s of the support grooves SG _{1 to} SG ₃ . When the projections p _{1 to} p ₃ come into contact with the stop plate s, the horizontal slide plate 5 stops and the tilt movement of the combiner C also stops.

  Next, an operation of returning the combiner C that has been tilted by the above operation to the storage position will be described. This operation is basically the above-described operation in which the combiner C in the housed state is in the unfolded state and then tilted.

First, when the rotation direction of a motor (not shown) is reversed in a state where the tilt operation is completed, the horizontal slide plate 5 moves in the direction of the rotation axis X toward the first guide plate 11 side. At this time, the projections _p 4, _{p 5} is the upper surface SS of the ribs 41 of the combiner support 4, it slides toward the side surface _{S R1} from the inclined side surfaces _{S TR.} Accordingly, the combiner C that has been tilted is shown in FIG. 9 by a torsion spring (not shown) disposed between the flat plate portion 30 of the upper and lower slide plate 3 and the holding plate portion 40 of the combiner support 4. The initial state parallel to the horizontal slide plate 5 is restored.

Next, when the horizontal slide plate 5 further moves toward the first guide plate 11, the projection p _{2 of} the horizontal slide plate 5 is moved into the cam groove of the upper and lower slide plates 3 as shown in FIGS. 5 (d) and 7 (d). Move to the front of the CG. As described above, the cam groove CG extends at an angle of 45 ° with respect to the vertical direction so that the upper end is located on the first guide plate 11 side and the lower end is located on the second guide plate 12 side. Yes. Therefore reaches the projection p ₂ within the cam groove CG, the further horizontal slide plate 5 and the projection p ₂ which is formed to move the first guide plate 11 side, the wall defining the cam groove CG push the projection p ₂ Moved downwards. As a result, the upper and lower slide plates 3 and the upper and lower racks VR formed on the upper and lower slide plates 3 also move downward, and as shown in FIGS. 5C and 7C, the upper and lower racks VR and the pinion gear Pn ₁ Are engaged.

When the horizontal slide plate 5 is further moved toward the first guide plate 11 from the state shown in FIGS. 5C and 7C, the horizontal rack HR is as shown in FIGS. 4B and 7A. moves in the first guide plate 11 side beyond the pinion gear Pn _1. Accordingly, the pinion gear Pn ₁ is detached from the horizontal rack HR, and the horizontal slide plate 5 stops.

On the other hand, the upper and lower racks VR mesh with the pinion gears Pn ₁ , Pn ₂ , and Pn ₃ in order, and return to the state shown in FIG. Thereby, the combiner C returns to the accommodation state shown to Fig.1 (a).

  The effects of the moving device M and the display device 100 of this embodiment are summarized below.

It can be a mechanism. The “mechanism for meshing the horizontal rack (axial rack) HR and the pinion gear (gear) Pn ₁ or the gear train when the vertical slide plate (vertical movable part) 3 moves to a predetermined height” As described above, in the process of accommodating the combiner C, when the horizontal slide plate (axially movable portion) 5 moves to a predetermined position in the rotation axis X direction, the function of meshing the upper and lower racks VR and the pinion gear (gear) Pn ₁ is provided. It may or may not have.

In the moving device M of the above-described embodiment, “the mover of the horizontal slide plate (axially movable portion) 5 tilts the combiner support (display plate holding portion) 4 with respect to the horizontal slide plate (axially movable portion) 5. as mechanism "that moved, the provided ribs 41 having the inclined side surface S _TR to combiner support 4, by contacting the projection p _4, p ₅ of the inclined side surface S _TR and horizontal slide plate 5 of the ribs 41, combiners support 4 and The tilt movement of the combiner C is performed. However, the mechanism for tilting and moving the combiner support 4 and the combiner C is not limited to this. As shown in FIG. 10, the plate-like protrusions p ₆ and p having the same inclined surface as the inclined side surface _STR are provided on the horizontal slide portion 5. ₇ may be provided, which may be brought into contact with the protrusions 43 formed on the combiner support 4 to tilt the combiner support 4 and the combiner C with respect to the horizontal slide plate 5. Further, the combiner support 4 may be provided with ribs 41 and the horizontal slide plate 5 may be provided with plate-like protrusions p ₆ and p ₇ . In this specification, like the rib 41 of the combiner support 4 and the projections p ₆ and p ₇ of the horizontal slide plate 5, the dimensions in the direction perpendicular to the vertical direction and the rotation axis X direction gradually change in the rotation axis X direction. The portion to be called is called “thickness changing portion”.

  The “mechanism for tilting the combiner support support (display plate holding portion) 4 with respect to the horizontal slide plate (axial movable portion) 5 by the movement of the horizontal slide plate (axial movable portion) 5” is “thick. It may be a mechanism that does not have a “change portion”.

  In the moving device M of the above embodiment, the upper and lower slide plates 3 and the horizontal slide plate 5 are not limited to plate-like members. However, in order to reduce the dimension of the moving device M in the direction orthogonal to the combiner C, it is preferable to use a member having a small dimension in the direction.

  In the moving device M of the above embodiment, the first guide plate 11 may not have the first guide rack 11r, and the second guide plate 12 may not have the second guide rack 12r. At this time, the synchronous pinion SPn may not be attached to the shaft SH.

  In the moving device M of the above-described embodiment, the first guide plate 11 may not have the first shaft guide groove 11g, and the second guide plate 12 may not have the second shaft guide groove 12g. . At this time, for example, the vertical slide plate 3 may be provided with a vertical through hole, and a guide shaft extending in the vertical direction may be inserted into the through hole to guide the vertical slide plate 3. In the moving device M of the above embodiment, the first and second guide plates 11 and 12 do not have to have the first and second shaft plate guide grooves 11a and 12a, and the upper and lower slide plates 3 have the boss 30a. You don't have to.

Incidentally, in the mobile device M of the embodiment, the upper and lower sliding plate 3 may not have any or all of the guide groove GG and support groove SG ₁ to SG _3. For example the vertical sliding plate 3, even if having only the support groove SG _2, by fitting the the projection p ₂ of the horizontal slide plate 5 and the supporting groove SG _2, good downward movement of the horizontal slide plate 5 Can be stopped. If no support groove _SG 1 to SG _3, for example first, second shaft guide groove 11g, 12 g of the upper end 11Gt, in the vicinity of the 12Gt, first, second guide groove 11g is urged by a spring or the like , 12g may be provided, and a pin may be provided to block the first and second shaft guide grooves 11g, 12g in the width direction, thereby restricting the downward movement of the shaft SH. When the pinion gear P _n1 is meshed with both the upper and lower racks VR and HR, the teeth and the guide groove CG that mesh with the pinion gear P _n1 at the beginning of the upper and lower racks VR are used in order to match the phases of the rack and the pinion. there distance, and is necessary to increase the initial dimensional accuracy of the distance between teeth meshing with the pinion gear P _n1 and the projection P ₂ horizontal rack HR. In that case, the upper and lower racks VR and the guide groove CG, is better projections p ₂ and horizontal rack HR is formed integrally respectively is advantageous.

  In addition, the transfer apparatus M of the said embodiment does not need to have the up-and-down slide plate 3. FIG. In this case, the horizontal rack VR and the cam groove CG can be provided on the surface of the combiner support 4 that faces the side plate 2. Further, in this case, when the combiner support 4 tilts, the downward movement of the shaft SH is regulated, for example, in the vicinity of the upper ends 11gt, 12gt of the first and second shaft guide grooves 11g, 12g. The first and second guide grooves 11g and 12g protrude from the side surfaces of the first and second guide grooves 11g and 12g, and a pin is provided to block the first and second shaft guide grooves 11g and 12g in the width direction. This pin restricts the downward movement of the shaft SH when the combiner support 4 is tilted. However, when the combiner support 4 is vertically moved, the pin is pushed by the shaft SH to be within the side surfaces of the first and second guide grooves 11g and 12g. The shaft SH is allowed to move up and down.

  In the moving device M of the above embodiment, the number of gears included in the gear train 6 is arbitrary. By increasing the number of pinion gears, the length of the upper and lower racks VR can be reduced, and by reducing the length of the upper and lower racks VR, the vertical dimension of the upper and lower slide plates 3 can be reduced. If the vertical dimension of the vertical slide plate 3 is reduced, the vertical dimension of the side plate 2, the first and second guide plates 11, 12 can be reduced, so that the vertical dimension of the entire moving device M can be reduced.

In the moving device M of the above embodiment, the pinion gear Pn ₁ may be a two-stage gear. In this case, for example, if the large first-stage gear of the module is meshed with the upper and lower racks VR and the smaller second-stage gear of the module is meshed with the horizontal rack HR, the rack-and-and-raft composed of the first-stage gear and the upper and lower racks VR is provided. The vertical slide plate 3 can be quickly moved up and down by the pinion mechanism, and at the same time, the moving speed of the horizontal slide plate 5 by the rack and pinion mechanism constituted by the second gear and the horizontal rack HR is slowed down, and the combiner support Fine adjustment of the tilt angle of 4 can be facilitated. Further, the number of teeth of the first gear and the number of teeth of the second gear may be varied in an appropriate combination.

In addition, an idle gear Ad ₃ that connects the pinion gear Pn ₁ and the pinion gear Pn ₄ can be provided. In this case, if the pinion gear Pn ₄ or the idle gear Ad ₃ is directly attached to the motor (not shown), the horizontal slide plate 5 can be moved in a state where the backlash is suppressed. Can be finely adjusted. Since the arrangement of the gears can be carried out in a small space on the side plate 2, upper and lower one of the gears constituting this way the gear train rather than a single pinion gear Pn ₁ (pinion gear Pn ₁ or pinion gear Pn ₄₎ The compact moving device M can be realized even if a configuration that meshes with the rack VR and the horizontal rack HR is used.

  When a cam groove inclined with respect to the vertical direction is used in a mode in which the vertical slide plate 3 and the horizontal slide plate 5 are moved at different speeds, the inclination angle of the cam groove with respect to the vertical direction is different from that of the vertical slide plate 3. It can be determined according to the speed ratio with the horizontal slide plate 5.

  In the moving device M of the above-described embodiment, the structure that connects the upper and lower slide plates 3 and the combiner support 4 so as to be relatively rotatable is not limited to the structure using the shaft SH. For example, the connecting portions 31 and 32 of the upper and lower slide plates 3 and the connecting portion 42 of the combiner support 4 may be connected by rivets.

  In the moving device M of the above embodiment, the number of ribs 41 of the combiner support 4 is not limited to two. The number of ribs 41 may be one, or three or more.

In the moving device M of the above embodiment, various tilt movements of the combiner C can be realized by appropriately designing the inclination angle θ of the inclined side surface _STR and the length in the rotation axis X direction. For example, when it is desired to precisely control the tilt angle of the combiner C, it is preferable to decrease the tilt angle θ and increase the length in the direction of the rotation axis X.

In the moving device M of the above-described embodiment, the protrusion p ₄ provided on the first overhanging portion 51 of the horizontal slide plate 5 and the protrusion p ₅ provided on the second overhanging portion 52 are formed on the rib 41. Although it was made to contact, it is not restricted to this. The first and second projecting portions 51 and 52 may be in direct contact with the rib 41, or when only one rib 41 is provided in the direction of the rotation axis X, the main body portion 50 of the horizontal slide plate 5. The end face on the second guide plate 12 side may be brought into contact with the rib 41.

  In the moving device M of the above embodiment, the motor for applying the rotational force to the gear train 6 can be arranged at an arbitrary position. Therefore, by attaching the motor to the side plate 2, the vertical dimension of the moving device M can be reduced.

In the moving device M of the above-described embodiment, the side surface SS of the rib 41 may be configured only by the inclined side surface _STR .

Incidentally, in the mobile device M of the embodiment, the motor pinion gear Pn ₁ directly, or when they are gears meshing closer to the pinion gear Pn _1, the most influence of the backlash is reduced, tilts with high accuracy It becomes possible.

In the moving device M of the above embodiment, the movement of the horizontal slide plate 5 and the upper and lower slide plates 3 is stopped when the projections p ₁ to p ₃ come into contact with the stop plate s. Depending on the method, it is possible to stop these movements prior to physical contact. At that time, if the stop plate s and the upper end 11gt or 12gt are provided, it will serve as a stopper when these movements overrun due to some trouble, and it is possible to prevent the gear and motor from being damaged. is there.
