And a display panel 5 which is a driven body that is driven to travel.

  The casing 2 has a rectangular and flat bottom portion 2a, and two side walls 2b and 2c that rise at right angles from three side edges of the bottom portion 2a. Each side wall 2b is extended along the insertion / extraction direction A, and the side wall 2c is connected to an end portion of each side wall 2b on the downstream side in the insertion direction A2 and extends in the insertion / extraction direction A within a virtual plane parallel to the bottom portion 2a. It extends along the orthogonal width direction B.

  Further, the housing 2 has an opening 2e formed by a side edge portion where the side wall of the bottom portion 2a is not provided and an end portion of each side wall 2b on the downstream side in the discharge direction A1. Each side wall 2b is formed with a plurality of (three in the present embodiment) convex portions 2d that protrude toward the side walls 2b facing each other. In each side wall 2b, the positions where the protrusions 2d are formed are positions in the vicinity of the opening 2e, in the vicinity of the approximate center in the insertion / extraction direction A, and in positions slightly advanced in the A1 direction from the downstream end of the discharge direction A2. .

  Each guide rail 3 is a member having a substantially L-shaped cross-section, and includes a linear attachment portion 3a that extends linearly and a guide portion 3b that rises at a right angle from a side edge of the attachment portion 3a. The guide rail 3 is attached to the housing 2 by fixing the contact portion with a fixing means such as a rivet in a state where the attachment portion 3a and the plurality of convex portions 2d are in contact with each other.

  Therefore, the guide rail 3 is attached so as to extend along the insertion / extraction direction A, and the guide rail 3 and the side wall 2b of the housing 2 are spaced apart from each other except for the contact portion. At this time, each guide rail 3 is attached to the housing 2 so that the respective guide portions 3b are arranged on the sides close to each other.

  Further, each guide rail 3 has a front end portion 3c on the downstream side in the discharge direction A1 of each guide rail 3 protruding from the opening 2e toward the outside of the housing 2. Further, the rear end portion 3d on the downstream side in the insertion direction A2 of each guide rail 3 extends along the A2 direction from a contact portion in contact with the adjacent convex portion 2d. That is, each guide rail 3 is attached to the housing 2 such that the front end portion 3c and the rear end portion 3d are free ends. Therefore, when a pressing force is applied to the front end portion 3c or the rear end portion 3d along the width direction B, the front end portion 3c or the rear end portion 3d is displaced in the pressing direction with elastic deformation. The guide portion 3b of each guide rail 3 will be described in detail later.

  A pair of racks 6 extending along the insertion / extraction direction A are fixed to the bottom 2 a of the housing 2. Each rack 6 is configured such that the travel drive 4 can travel in the discharge direction A1 and the insertion direction A2 by meshing with the pinions of the travel drive means 4a mounted on the travel drive 4 respectively. Has been.

  The traveling drive unit 4 is equipped with a traveling drive unit 4a, a tilt driving unit 4b, and a control unit 4c. These units 4a to 4c are mounted on and mounted on a movable portion 4d having a rectangular plate shape. The movable portion 4d is disposed to face the rack 6 so as to be parallel to the bottom portion 2a, and the pinion is interposed between the movable portion 4d and the rack 6.

  Further, the movable portion 4d is provided with side wall portions 4e that rise at right angles from the two side edges of the movable portion 4d, and the first fitting grooves 7 are formed in the respective side wall portions 4e. . Each first fitting groove 7 is a rectangular groove extending along the insertion / ejection direction A, and upper and lower wall surfaces 7a parallel to the movable portion 4d and upper and lower wall surfaces perpendicular to the upper and lower wall surfaces 7a. 7a and a bottom surface 7b connecting the lower wall surface 7a. Each first fitting groove 7 is formed so that the groove width W1 and the groove depth D1 are uniform over the extending direction of the groove. The travel drive body 4 travels in a state in which guide portions 3b of the guide rails 3 described later are fitted into the first fitting grooves 7 formed in this way.

  Further, second fitting grooves 8 are respectively formed at both end portions in the width direction B of the display panel 5. Each second fitting groove 8 is a rectangular groove extending along the insertion / ejection direction A, and upper and lower wall surfaces 8a parallel to the movable portion 4d and upper and lower wall surfaces perpendicular to the upper and lower wall surfaces 8a. 8a and a bottom surface 8b connecting the lower wall surface 8a. Each second fitting groove 8 is formed so as to be continuous with each first fitting groove 7 formed in the adjacent traveling drive body 4. Each of the second fitting grooves 8 has a groove width W2 that is substantially the same as the groove width W1 of the first fitting groove 7, and has a groove depth D2 that is larger than the groove depth D1 of the first fitting groove 7. Formed as follows. The display panel 5 is driven to travel by the travel drive body 4 in a state in which the guide portions 3b of the guide rails 3 to be described later are fitted in the second fitting grooves 8 formed in this way.

  The travel drive body 4 can be travel driven across the insertion position P <b> 1 and the discharge position P <b> 2, and the display panel 5 connected to the end of the travel drive body 4 on the downstream side in the discharge direction A <b> 1 As a result, the vehicle is driven. In the insertion position P1, the traveling drive body 4 has an end on the downstream side in the insertion direction A2 of the traveling drive body 4 between the rear end portions 3d of the pair of guide rails 3, and the traveling drive body 4 is driven at the discharge position P2. An end of the body 4 on the downstream side in the discharge direction A1 exists between the front end portions 3c of the pair of guide rails 3. Further, when the traveling drive body 4 is disposed at the insertion position P1, the display panel 5 has an end portion on the downstream side in the discharge direction A1 of the display panel 5 between the front end portions 3c of the pair of guide rails 3. ing.

  Hereinafter, each means 4a-4c mounted in the traveling drive body 4 is demonstrated. The travel drive means 4a is configured to decelerate and transmit the rotation of the output shaft of the motor to the pinion by a gear train composed of a plurality of gears. Further, the tilt driving means 4b angularly displaces the display panel 5 around the axis line J1 parallel to the width direction B at the downstream end of the discharge direction A1. The tilt drive means 4b, like the travel drive means 4a, decelerates the rotation of the output shaft of the motor by a gear train composed of a plurality of gears, and causes the display panel 5 to stand around the axis J1 in the standing direction C1 and the recumbent direction. It is configured so that it can be tilted to C2.

  These travel drive means 4 a and tilt drive means 4 b are controlled by a control means 4 c mounted on the travel drive body 4. When the traveling drive body 4 is disposed at the insertion position P1, the control unit 4c stops the driving power to the motor of the traveling drive unit 4a and stops the movement in the insertion direction A2. Further, when the travel drive means 4a is arranged at the discharge position P2 downstream of the guide rails 3 in the discharge direction A1, the motor of the tilt drive means 4b is operated to make the display panel 5 parallel to the travel drive body 4. Then, the tilting operation of the display panel 5 is stopped by stopping the supply of driving power to the motor of the tilt driving means 4b.

  Further, when the operator presses a storage button (not shown) to give a storage command to the control means 4c, the output shaft of the motor of the tilt drive means 4b is driven to rotate in the direction opposite to that at the time of discharge, and the display is in the standing state. When the panel 5 is angularly displaced in the recumbent direction C2 and becomes parallel to the traveling drive body 4, the operation of the recumbent direction C2 is stopped, and then the motor output shaft of the traveling drive means 4a is rotationally driven in the direction opposite to that during discharging. The display panel 5 is moved and pulled in the insertion direction A2 by the traveling drive body 4. When it is detected by a detection switch (not shown) that the travel drive body 4 has reached the insertion position P1, the control means 4c stops supplying power to the motor of the travel drive means 4a, and the travel drive body 4 is moved to the insertion position P1. Stop.

  Hereinafter, the guide part 3b of the guide rail 3 fitted in the first fitting groove 7 and the second fitting groove 8 will be described. The guide portion 3b has a substantially uniform plate thickness T smaller than the groove widths W1 and W2 of each groove from the front end portion 3c to the rear end portion 3d, whereas the dimension in the width direction B is along the insertion / extraction direction A. Are formed differently. Specifically, the intermediate portion 3f between the front end portion 3c and the rear end portion 3d is formed so that the dimension in the width direction B is constant. In the intermediate portion 3f, as shown in FIG. The insertion amount H of the guide portion 3b is formed so as to be smaller than the groove depth D1 of the first fitting groove 7 with respect to the first fitting groove 7 of the traveling drive body 4 in the intermediate portion 3f. ing. With respect to the intermediate portion 3f, the front end portion 3c and the rear end portion 3d are respectively formed with raised portions 3e protruding in a direction approaching the opposing guide rail 3. Each protruding portion 3e is formed such that the protruding amount increases from the intermediate portion 3f toward the front end portions of the front end portion 3c and the rear end portion 3d. That is, the guide rails 3 are closest to each other at the front end portion of each front end portion 3c and the front end portion of each rear end portion 3d. Further, as shown in FIG. 5, the dimension M1 between the front end parts closest to each other in the front end part 3c and the rear end part 3d is smaller than the dimension M2 between the bottom surfaces 7b of the pair of first fitting grooves 7. It is formed as follows.

  Since the guide rail 3 is formed in this way, the traveling drive body 4 operates because the guide portions 3b and the first fitting grooves 7 are not in contact with each other at the intermediate portion 3f when moving to the insertion position P1. While moving without receiving a load, when approaching the insertion position P1, first, the bottom surface 7b of each first fitting groove 7 and each raised portion 3e come into contact with each other. 3e is pressed, and each rear end 3d is moved to the insertion position P1 while being displaced in a direction away from each other. That is, the traveling drive body 4 moves to the insertion position P1 while increasing the contact pressure to each guide rail 3.

  Similarly, when the traveling drive body 4 moves to the discharge position P2, in the intermediate portion 3f, the guide portions 3b and the first fitting grooves 7 do not come into contact with each other, so that the travel drive body 4 moves without receiving an operating load. When approaching the discharge position P2, first, the bottom surface 7b of each first fitting groove 7 and each raised portion 3e come into contact with each other, and when further proceeding to the discharge position P2, each raised portion 3e is pressed to each front end portion 3c. Are moved to the discharge position P2 while being displaced in directions away from each other. That is, the traveling drive body 4 moves to the discharge position P2 while increasing the contact pressure to each guide rail 3.

  The travel drive body 4 that has moved while pressing and displacing the guide rails 3 in this way is caused to move back to the original position of the displaced guide rails 3 by the elastic force at the insertion position P1 and the discharge position P2. The rear end portion 3d and the front end portion 3c are pressed and fixed from both sides in the width direction B. Therefore, the traveling drive body 4 in such a fixed state is prevented from vibrating due to external vibrations, and thus is generated by contact between the traveling drive body 4 and the guide rail 3 due to vibration. You can eliminate the noise that you were doing.

  Further, the second fitting groove 8 is set so that the dimension M3 between the bottom surfaces 8b forming the pair of second fitting parts 8 in the display panel 5 is smaller than the dimension M1 between the front end parts of the front end part 3c described above. When the traveling drive body 4 is moved between the insertion position P1 and the discharge position P2, the second fittings of the display panel 5 and the raised portions 3e of the front end portion 3c are determined. Since there is no contact with the joint groove 8, it is prevented from receiving an operation load, and the traveling drive body 4 and the display panel 5 can be driven to travel without exerting a large driving force.

  Further, among the second fitting grooves 8 formed in the display panel 5, the groove depth is set so that the second fitting groove 8 and the raised portion 3e of the front end portion 3c are in contact with each other on the downstream side in the discharge direction A1. When the travel drive body 4 is moved to the insertion position P1, the travel drive body 4 is fixed by the rear end portions 3d of the guide rails 3 and the display panel 5 is fixed to each of the guide rails 3 by forming it shallow. It can be fixed by the front end 3c. Therefore, it is possible to prevent the display panel 5 from vibrating due to external vibration, and it is possible to eliminate the abnormal noise generated by the contact between the display panel 5 and the guide rail 3.

  FIG. 6 is a plan view showing the vicinity of the front end portion 10c of the guide rail 10 constituting the guide device for the electronic device movable portion according to another embodiment of the present invention. In addition, the electronic apparatus movable part guide apparatus according to the present embodiment is configured in the same manner as the above-described electronic apparatus movable part guide apparatus except for the configuration of the guide rail 10, and therefore, the same components are denoted by the same reference numerals. The description which overlaps is abbreviate | omitted. The four end portions 10c and 10d of the pair of guide rails 10 are formed in the same manner.

  Each of the pair of guide rails 10 is a member having a substantially L-shaped cross section, and includes an attachment portion 10a and a guide portion 10b that rises at a right angle from a side edge of the attachment portion 10a. The guide rail 10 is attached to the housing 2 by fixing the contact portion using a fixing means such as a rivet in a state where the mounting portion 10a and the plurality of convex portions 2d are in contact.

  Therefore, the guide rail 10 is attached so as to extend along the insertion / ejection direction A, and the guide rail 10 and the side wall 2b of the housing 2 are spaced apart from each other except for the contact portion. At this time, each guide rail 10 is attached to the housing 2 so that the respective guide portions 10b are arranged on the sides close to each other.

  Further, each guide rail 10 has a front end portion 10c on the downstream side in the discharge direction A1 of each guide rail 10 protruding from the opening 2e toward the outside of the housing 2. Further, the rear end portion 10d on the downstream side in the insertion direction A2 of each guide rail 10 extends along the A2 direction from a contact portion that is in contact with the adjacent convex portion 2d. That is, each guide rail 10 is attached to the housing 2 such that the front end portion 10c and the rear end portion 10d are free ends. Therefore, when a pressing force is applied along the width direction B to the front end portion 10c or the rear end portion 10d, the front end portion 10c or the rear end portion 10d is displaced in the pressing direction with elastic deformation.

  The guide portion 10b has a substantially uniform plate thickness T smaller than the groove widths W1, W2 of each groove from the front end portion 10c to the rear end portion 10d, and the dimension in the width direction B is also uniform along the insertion / extraction direction A. It is formed to become.

  A feature of the guide rail 10 used in the present embodiment is that the front end portion 10c and the rear end portion 10d are bent in directions close to each other. Specifically, the intermediate portion 10f between the front end portion 10c and the rear end portion 10d is formed so as to extend linearly along the insertion / extraction direction A, and the first fitting of the traveling drive body 4 in the intermediate portion 10f. With respect to the joint groove 7, the insertion amount H of the guide portion 10 b is formed to have a dimension that is smaller than the groove depth D 1 of the first fitting groove 7. With respect to the intermediate portion 10f, the front end portion 10c and the rear end portion 10d are bent in directions close to each other, and the guide portion 10b is deformed so as to be directed in a direction close to the opposing guide rail 10. Each front end portion 10c and each rear end portion 10d are deformed so as to be closer to each other from the intermediate portion 10f toward the front end portions of the front end portion 10c and the rear end portion 10d. That is, the guide rails 10 are closest to each other at the front end portion of each front end portion 10c and the front end portion of each rear end portion 10d. Further, the front end 10c and the rear end 10d are formed such that a dimension M4 between the front end portions closest to each other is smaller than a dimension M2 between the bottom surfaces 7b of the pair of first fitting grooves 7.

  Since the guide rail 10 is formed in this way, the traveling drive body 4 operates because the guide portions 10b and the first fitting grooves 7 are not in contact with each other at the intermediate portion 10f when moving to the insertion position P1. While moving without receiving a load, when approaching the insertion position P1, first, the bottom surface 7b of each first fitting groove 7 and each rear end portion 10d come into contact with each other, and when further proceeding to the insertion position P1, The end portion 10d is pressed and moved to the insertion position P1 while the rear end portions 10d are displaced in directions away from each other. That is, the traveling drive body 4 moves to the insertion position P1 while increasing the contact pressure to each guide rail 10.

  Similarly, when the traveling drive body 4 moves to the discharge position P2, in the intermediate portion 10f, the guide portions 10b and the first fitting grooves 7 do not come into contact with each other, and thus move without receiving an operation load. When approaching the discharge position P2, first, the bottom surface 7b of each first fitting groove 7 and each front end portion 10c come into contact with each other, and when further proceeding to the discharge position P2, each front end portion 10c is pressed to each front end portion 10c. Are moved to the discharge position P2 while being displaced in directions away from each other. That is, the traveling drive body 4 moves to the discharge position P2 while increasing the contact pressure to each guide rail 10.

  The travel drive body 4 that has moved while pressing and displacing the guide rails 10 in this way is caused to move back to the original position of the displaced guide rails 10 by the elastic force at the insertion position P1 and the discharge position P2. The rear end portion 10d and the front end portion 10c are pressed and fixed from both sides in the width direction B. Therefore, the traveling drive body 4 in this fixed state is prevented from vibrating due to external vibrations, and thus is generated by contact between the traveling drive body 4 and the guide rail 10 due to vibration. You can eliminate the noise that you were doing.

  FIG. 7 is a perspective view showing the vicinity of a front end portion 11c of a guide rail 11 constituting a guide device for an electronic device movable portion according to still another embodiment of the present invention. In addition, the electronic apparatus movable part guide apparatus of the present embodiment is configured in the same manner as the above-described electronic apparatus movable part guide apparatus except for the configuration of the guide rail 11, and thus the same reference numerals are used for the same configurations. The description which overlaps is abbreviate | omitted. The four end portions 11c and 11d of the pair of guide rails 11 are formed in the same manner.

  The pair of guide rails 11 have substantially the same shape as the above-described guide rail 10, and the guide rail 10 is guided while the front end portion 10c and the rear end portion 10d are bent with respect to the intermediate portion 10f. In the rail 11, a narrowed portion 11e is formed in the guide portion 11b at the front end portion of the front end portion 11c and the rear end portion 11d. The throttle portion 11e is formed such that the dimension in the thickness direction (Z direction) is larger than the groove width W1 of the first fitting groove 7 and the groove width W2 of the second fitting groove 8.

  Since the guide rail 11 is formed in this way, the traveling drive body 4 operates because the guide portions 11b and the first fitting grooves 7 do not come into contact with each other in the intermediate portion 11f when moving to the insertion position P1. While moving without receiving a load, when approaching the insertion position P1, the upper and lower wall surfaces 7a of each first fitting groove 7 come into contact with the throttle portion 11e of each rear end portion 11d, and the insertion position P1. When moving to the insertion position P1, it moves to the insertion position P1 while pressing each throttle part 11e. That is, the traveling drive body 4 moves to the insertion position P1 while increasing the contact pressure of each guide rail 11 to each throttle portion 11e.

  Similarly, when the traveling drive body 4 moves to the discharge position P2, in the intermediate portion 11f, the guide portions 11b and the first fitting grooves 7 do not come into contact with each other, and thus move without receiving an operating load. When approaching the discharge position P2, the upper and lower wall surfaces 7a of the first fitting grooves 7 come into contact with the throttle portions 11e of the front end portions 11c, and further press the respective throttle portions 11e when proceeding to the discharge position P2. While moving to the discharge position P2. That is, the traveling drive body 4 moves to the discharge position P2 while increasing the contact pressure to each guide rail 10.

  Thus, the travel drive body 4 that has moved while pressing each throttle portion 11e of each guide rail 11 is guided by the elastic recovery force of each throttle portion 11e that is elastically deformed by the press at the insertion position P1 and the discharge position P2. 11 is fixed. Therefore, the traveling drive body 4 in this fixed state is prevented from vibrating due to external vibrations, and thus is generated by contact between the traveling drive body 4 and the guide rail 11 due to vibration. You can eliminate the noise that you were doing.

  FIG. 8 is a diagram in which each guide portion 12b of a pair of guide rails 12p and 12q constituting a guide device for a movable part of an electronic device according to still another embodiment of the present invention is projected on a virtual plane perpendicular to the width direction B. It is. In addition, the electronic apparatus movable part guide apparatus of the present embodiment is configured in the same manner as the above-described electronic apparatus movable part guide apparatus except for the configuration of the guide rail 12, and therefore, the same reference numerals are used for the same configurations. The description which overlaps is abbreviate | omitted.

  The pair of guide rails 12 has substantially the same shape as the above-described guide rail 3, and has a shape in which the raised portion 3e formed on the guide rail 3 is not formed. That is, each guide rail 12 has a linear mounting portion 12a that extends linearly and a guide portion 12b that rises at a right angle from a side edge of the mounting portion 12a. The guide portion 12b extends from the front end portion 12c to the rear end. The portion 12d has a substantially uniform plate thickness T smaller than the groove widths W1 and W2 of the respective grooves, and the dimension in the width direction B is also uniform along the insertion / extraction direction A.

  The guide rail 12 used in the present embodiment is characterized in how to attach it to the housing 2. Each guide rail 12p, 12q is attached so as to be inclined in the vertical direction (Z direction) with respect to an axis extending in a direction parallel to the insertion / ejection direction A. Specifically, one guide rail 12p is attached so as to incline toward one side in the Z direction (Z1 direction) as it goes downstream in the insertion direction A2, and the other guide rail 12q is downstream in the insertion direction A2. It is attached so that it may incline toward the other (Z2 direction) of Z direction as it progresses. At this time, the guide rails 12p and 12q are arranged and attached so that the center of the guide rails 12p and 12q in the insertion / extraction direction A is located on a virtual plane U perpendicular to the Z direction.

  Since the guide rails 12p and 12q are attached in this manner, when the traveling drive body 4 moves to the insertion position P1, the guide portions 12b and the first fitting grooves 7 do not come into contact with each other at the intermediate portion 12f. While moving without receiving an operating load, when approaching the insertion position P1, the upper wall surface 7a of one first fitting groove 7 and the guide portion 12b of the guide rail 12p are in contact with each other, and the other first fitting is performed. The lower wall surface 7a of the joint groove 7 and the guide portion 12b of the guide rail 12q come into contact with each other. Then, when further proceeding to the insertion position P1, the upper wall surface 7a of one first fitting groove 7 presses the guide portion 12b of the guide rail 12p downward (Z2 direction) and the other first fitting groove 7 The lower wall surface 7a moves to the insertion position P1 while pressing the guide portion 12b of the guide rail 12q upward (Z1 direction). That is, the traveling drive body 4 moves to the insertion position P1 while increasing the contact pressure to each guide rail 12p, 12q.

  Similarly, when the travel drive body 4 moves to the discharge position P2, the travel drive body 4 receives an operation load at the intermediate portion 12f because the guide portions 12b and the first fitting grooves 7 do not contact each other. In contrast, when moving closer to the discharge position P2, the lower wall surface 7a of the first fitting groove 7 and the guide portion 12b of the guide rail 12p are in contact with each other, and the upper surface of the other first fitting groove 7 is over. The wall surface 7a and the guide portion 12b of the guide rail 12q come into contact with each other. Then, when further proceeding to the discharge position P2, the lower wall surface 7a of one first fitting groove 7 presses the guide portion 12b of the guide rail 12p upward (Z1 direction), and the other first fitting groove 7 The lower wall surface 7a moves to the discharge position P2 while pressing the guide portion 12b of the guide rail 12q downward (Z2 direction). That is, the traveling drive body 4 moves to the discharge position P2 while increasing the contact pressure to each guide rail 12p, 12q.

  The travel drive body 4 that has moved while pressing the guide portions 12b of the guide rails 12p and 12q in this way is elastically recovered by the guide portions 12b that are displaced by the elastic deformation caused by the press at the insertion position P1 and the discharge position P2. By causing the forces to act in opposite directions on both sides of the traveling drive body 4, they are fixed by the guide rails 12 p and 12 q. Therefore, the traveling drive body 4 in such a fixed state is prevented from vibrating due to external vibrations, and thus is caused by vibrations of the traveling drive body 4 and the guide rails 12p and 12q. Abnormal noise generated by contact can be eliminated.
