And is supported at a predetermined height from the bottom plate 3.

  The fixed side plate 4 is a plate material in which a large number of support grooves 17 are formed in parallel on the inner surface (the surface facing the movable side plate 5). In this embodiment, two fixed side plates 4 are provided in the longitudinal direction in front of and behind the outer surface. The unit plate 18 is attached to a vertical member in a state of being stacked in a plurality of stages (five stages in the drawing).

  On the other hand, the movable side plate 5 is a plate material in which a large number of support grooves 17 are formed in parallel on the inner surface (the surface facing the fixed side plate 4). In the present embodiment, the movable side plate 5 is provided in the longitudinal direction in front of and behind the outer surface. Although it is the same as the fixed side plate 4 in that the unit plate is attached to the vertical member (hat type material) 20 in a state where it is stacked in a plurality of stages, it is X while maintaining a state parallel to the fixed side plate 4. In order to be able to move in the axial direction, a shaft 21 is provided along the Y-axis direction in the vicinity of the lower side and the upper side, pinion gears 22 are attached to both ends of the shaft 21, and each pinion gear 22 is attached to the rack gear 12 on the upper surface of the step.

Next, the clamp mechanism 6 that fixes the moved movable side plate 5 will be described.
The clamp mechanism 6 shown in FIG. 5 is a pinching type, and includes a slider 27 that is attached to the upper and lower ends of the longitudinal member 20 of the movable side plate 5 and has a fixed piece 26 having mounting holes 25, a top plate 2, and a bottom plate 3. A flange-shaped head 29 larger than the width of the long hole 14 is provided at the end of the tension rod 28 penetrating into the long hole 14 opened at the end, and a shaft-attached piece with a shaft hole at the end opposite to the head 29 A pin 32 is inserted into a pinching member 31 having a pin 30 and a shaft hole 32 having an opening on the side face in a state where the pinned member 30 with a shaft hole of the pinching member 31 is inserted into the empty portion. When the clamping member 31 is attached through the shaft hole of one piece and one end portion far from the shaft hole 32 is rotated, the cam surface 33 formed around the other end portion close to the shaft hole 32 is formed. The operation lever body 34 presses the fixed piece 26. As shown in FIG. 5, the cam surface 33 of the operation lever main body 34 is a distance between the surface of the operation lever main body 34 that contacts the fixed piece 26 and the shaft hole 32 in the first state where the operation lever main body 34 stands up with respect to the fixed piece 26. And the distance between the surface that contacts the fixed piece 26 and the shaft hole 32 in the second state (FIGS. 3 and 4) in which the operation lever body 34 is turned in the direction of the arrow and tilted, the operation lever body 34 is raised. The distance in the first state is formed to be larger than the distance in the second state. Therefore, in the second state in which the operation lever main body 34 is tilted, the edge of the long hole 14 is not strongly pinched between the cam surface and the head 29, and the released state (unlocked state) is established. When all the clamp mechanisms 6 provided at the four corners of the movable side plate 5 are brought into the unlocked state, the movable side plate 5 can be arbitrarily moved by pushing it by hand. On the other hand, when the operation lever main body 34 is rotated to change from the second state to the first state, the distance between the cam surface 33 that contacts the fixed piece 26 and the shaft 32 ′ increases. In this state, the edge of the long hole 14 is firmly sandwiched and fixed between them (locked state), and even if the movable side plate 5 is pushed by hand, it does not move. In addition, the clamp mechanism 6 is provided at the upper left and right sides of the movable side plate 5 so that it can be operated from the outside of the movable side plate 5, and is moved to the second state (unlocked state) with the operation lever body 34 rotated downward. Those provided on the left and right sides of the lower end are in the first state (locked state) when the operation lever main body 34 is rotated upward, and the upper end of the operation lever main body 34 is rotated upward to fix the fixed piece 26. When the control lever main body 34 at the lower end is turned and raised, the first state (locked state) is obtained.

Next, the interlocking mechanism 8 that interlocks the above-described operation lever (operation lever main body 34) will be described.
The interlocking mechanism 8 is attached to the movable side plate 5 and interlocks the operation levers of all the clamp mechanisms 6. In this embodiment, the holder 40 is attached to the operation lever main body 34 and integrated with the operation lever. 41, a rod-shaped lower link member 42 that connects the two operation levers 41 of the clamp mechanism 6 provided at both lower (lower) corners of the movable side plate 5 and interlocks the movements of the two operation levers 41, and the movable side plate 5 A rod-shaped upper link member 43 that connects the two operation levers 41 of the clamp mechanism 6 disposed at both corners on the upper side (upper part) of the two and connects the movements of the two operation levers 41, and the length of the upper link member 43. The upper cross joint 44a is provided in the middle of the direction (substantially in the middle) and is slidable along the longitudinal direction of the upper link member 43. The lower cross joint 44b that is slidable along the longitudinal direction of the lower link member 42 and the horizontally long upper beam member 45 that connects the upper portions of the longitudinal members 20 of the movable side plate 5 (almost the center in the longitudinal direction). The upper bearing portion 46 provided in the upper portion, the lower bearing portion 48 provided in the middle of the horizontally long lower beam member 47 connecting the lower portions of the vertical members 20 (approximately the center in the longitudinal direction), and the lower bearing portion 48 and the upper The rotary shaft 49 is supported by the bearing portion 46 and is schematically constituted by a vertically connecting link member 50 that can rotate. The upper and lower connecting link member 50 includes an upper extension portion 51 and a lower extension portion 52 that extend in the horizontal direction orthogonal to the rotation shaft 49, and is provided at the tip of the upper extension portion 51. A rotation shaft 51 ′ formed in the vertical direction is the rotation bearing portion of the upper cross joint 44 a, and a rotation shaft 52 ′ formed in the vertical direction at the tip of the lower extension 52 is the rotation of the lower cross joint 44 b. It is fixed to the bearing part so as to be rotatable at the same phase.

  As shown in FIG. 6, the holder 40 of the operation lever 41 is a plastic lever having a hollow portion 53 into which the operation lever main body 34 is inserted, and the end of the lower link member 42 or the upper link member 43 is attached to the side surface. When the free end side of the operating lever main body 34 is inserted into the above-described empty portion 53 and then fixed to the fixing screw hole 54b with a screw (not shown), the link mounting portion 54a is integrated with the operating lever main body 34. .

  The cross joint 44 includes a link member penetrating space 55 that encloses the link members 42 and 43 in the Y-axis direction in a state in which the link members 42 and 43 can be slid relatively to the left and right. This is a plastic member formed with a through-shaft portion 56 for a rotating shaft that penetrates the formed rotating shafts 51 ′ and 52 ′ so as to be rotatable and slidable up and down. It is shaped so that the axial direction of the portion 55 and the axial direction of the through-opening hollow portion 56 are perpendicular to each other. When attaching, the link member penetrating space 55 is positioned closer to the beam members 45 and 47 of the movable side plate 5. And this cross joint 44 does not rotate according to the position of the link member which penetrates the inside of the through-hole part 55 for link members, and the position of the rotation axis which penetrates the inside of the penetration space part 56 for rotation shafts. It moves three-dimensionally in the same posture and smoothly transmits the direction of the driving force between the link member and the rotating shaft. The actual movement will be described in detail later.

  Moreover, in this embodiment, the state maintenance mechanism which maintains a 1st state or a 2nd state is provided. As shown in FIG. 7, this state maintaining mechanism is provided in the vicinity of the bearing, and a state maintaining cam 60 is attached in the vicinity of the bent portion of the rotating shaft 49 of the upper and lower connecting link member 50. The cam follower 62 is brought into pressure contact with 61 to restrict the rotation of the upper and lower connecting link member 50 so that the state is maintained.

  The state maintaining cam 60 is provided with a shaft hole through which the rotation shaft 49 of the upper and lower connecting link member 50 passes at the center of rotation, and a hollow portion having an inner surface along the cam surface shape inside the cam surface 61 formed on the outer periphery. 63, and the thickness of the belt-like portion between the cam surface 61 and the hollow portion 63 is made substantially the same, and the arm portion 65 is formed on the opposite side of the cam surface 61 across the shaft hole, The extending portion 52 is attached to the shaft hole by fitting it into the groove 66 of the arm portion 65 of the cam 60 through the upper and lower connecting link member 50.

  On the other hand, the cam follower 62 is integrally formed with the beam member as a protrusion on the upper beam member 45 or the lower beam member 47 provided with the bearings 46 and 48. Although the cam follower 62 is stationary, the cam surface 61 of the state maintaining cam 60 has elasticity due to the bending restoring force of the belt-shaped portion between the cam follower 62 and the cam surface 61. By pressing, the upper and lower connecting link members 50 are maintained in a predetermined phase, and the state of the operation lever 41 is maintained. In this way, when the empty portion 63 is formed on the back side of the cam surface 61 of the cam 60, an elastic restoring force can be applied to the cam surface 61 without excess or deficiency, and there is no need to provide a spring for urging the cam follower. Therefore, the configuration can be simplified.

An operation of adjustment work for adjusting the position of the movable side plate 5 in accordance with the width of the plate material in the plate material storage rack 1 having the interlocking mechanism 8 having the above-described configuration will be described. Each clamp mechanism 6 is in a fixed state (first state) as shown in FIG. 2, and the top ends of the upper extension portion 51 and the lower extension portion 52 of the upper and lower connecting link member 50 are directed to the beam side. It is assumed that it is in a state where it is brought close and tilted along the movable side plate 5.
First, in a state where the movable side plate 5 is fixed, that is, in a first state in which all the operation levers 41 are tilted along the movable side plate 5, when any one of the operation levers 41 is rotated, the interlock mechanism 8 is moved. Accordingly, the other operation levers 41 move all at once in conjunction with the rotation of the one operation lever 41 and change from the first state to the second state. That is, when one operation lever 41 of the clamp mechanism 6 disposed above is rotated in a direction in which the free end side is raised, the upper link member 43 connected to the operation lever 41 is moved to the operation lever 41. The Y-axis counterclockwise (in the direction of arrow A in FIG. 2) moves in an arc in synchronization with the movement of the upper link member 43, and the upper cross joint 44 a rises as the upper link member 43 moves in an arc. While moving outward (in a direction away from the moving side plate), the upper cross joint 44a moves the tip of the upper extending portion 51 of the upper and lower connecting link member 50 to the rotation shaft 49 by moving the arc outward of the upper cross joint 44a. 2 is rotated in the direction of arrow B in FIG. 2, and the upper cross joint 44a follows the upper link member 43 along with the rotation. Moves (slides) on the front side (left side in FIG. 2) Te. In this way, when the upper and lower connecting link member 50 rotates in the direction in which the tip of the upper extension portion 51 moves forward, the tip of the lower extension portion 52 moves forward while moving outward due to this rotation. As a result, the lower cross joint 44b moves downward while moving downward, and the movement of the lower cross joint 44b causes the lower link member 42 to move circularly in the Y-axis clockwise direction (in the direction of arrow C in FIG. 2). The operation lever 41 of the clamp mechanism 6 disposed below is rotated in the direction of descending the free end by the circular movement of the member 42. When the remaining three operation levers 41 are sufficiently rotated by the operation of one operation lever 41 to convert to the second state, all the operation levers 41 are raised with respect to the movable side plate 5 as shown in FIG. As described above, the edge of the elongated hole 14 is firmly clamped between the cam surface 33 of the operation lever main body 34 and the head 29 of the clamping member 31 (the locked state) so as to be strongly clamped. Convert to a release state (unlocked or unlocked) that cannot be attached. Therefore, when converted to this second state, the movable side plate 5 can be freely moved, and the width of the substrate is determined by, for example, positioning the printed board to be accommodated between the fixed side plate 4 and the movable side plate 5 and sandwiching it from both sides. Accordingly, the movable side plate 5 can be moved and positioned.

When the movable side plate 5 is positioned by the above-described operation, the operator selects the operation lever 41 that is most easily operated by the operator, for example, the closest operation lever 41 that allows easy hand movement, and rotates the operation lever 41. When the moving operation is performed, the other operating levers 41 are moved together in conjunction with the rotation of the first operating lever 41 via the interlocking mechanism 8 to change from the second state to the first state.
Specifically, for example, when the operation lever 41 of the clamp mechanism 6 disposed on the lower side is rotated in the direction of raising the free end side, the lower link member 42 connected to the operation lever 41 is moved. The Y-axis counterclockwise (in the direction of arrow D in FIG. 3) moves in an arc in synchronization with the movement of the operation lever 41, and the lower link joint 44 b moves along with the arc movement of the lower link member 42 due to the arc movement of the lower link member 42. 3 and moves inwardly (in a direction approaching the moving side plate), and the lower cross joint 44b moves the tip of the lower extension portion 52 of the upper and lower connecting link member 50 in FIG. It rotates in the direction of arrow E, and the lower cross joint 44b moves to the back side along the lower link member 42 along with this rotation. In this way, when the upper and lower connecting link member 50 rotates in the direction in which the tip of the lower extension portion 52 moves to the back side, the tip of the upper extension portion 51 moves inward while moving in the direction by this rotation. As a result, the upper cross joint 44a moves downward while moving downward, and the movement of the upper cross joint 44a causes the upper link member 43 to move circularly in the Y-axis clockwise direction (in the direction of arrow F in FIG. 3). Due to the circular movement of the upper link member 43, the operation lever 41 of the clamp mechanism 6 disposed above rotates in the direction of arrow F that descends the free end. Then, when the remaining three operation levers 41 are also sufficiently rotated by the operation of the operation lever 41 on the lower front side, as shown in FIG. 2, all the operation levers 41 fall from the second state in which they stand up with respect to the movable side plate 5. The first state is restored, and as described above, the edge of the long hole 14 is firmly clamped between the cam surface 33 of the operation lever main body 34 and the head 29 of the pinching member 31 (the locked state). ). Therefore, when the locked state is restored, the movable side plate 5 cannot be freely moved, and is fixed at a position positioned corresponding to the printed circuit board to be stored. As a result, the distance between the fixed side plate 4 and the movable side plate 5 becomes an interval suitable for the width of the substrate, and the substrate can be smoothly inserted into the rack from the opening 10 and stored, and can be taken out smoothly.

  In the above-described embodiment, the operation lever 41 is operated to transmit the movement of the operation lever 41 to the other operation lever 41 via the interlocking mechanism 8. The invention may be configured such that all the operation levers 41 are moved simultaneously through the interlocking mechanism 8 by operating a part of the interlocking mechanism 8.

For example, the plate material storage rack 1 shown in FIG. 8 and FIG. 9 is bent in a rectangular wave shape in the same direction as the upper and lower extending portions 51 and 52 around the upper and lower center of the rotating shaft 49 of the upper and lower connecting link member 50. The part is the operation unit 70, and other configurations are the same as those of the above-described embodiment.
Therefore, in this embodiment, even if the operation part of the upper and lower connecting link member 50 is operated or the arbitrary operation lever 41 is operated, the first state can be similarly converted to the second state, and vice versa. An operation for returning the two states to the first state can also be performed.
Further, the upper and lower connecting link member 50 is not limited to the one formed by bending a metal wire, but is supported in a rotatable state at a portion corresponding to the rotating shaft 49, and is an extension portion when rotated. For example, a plate-like member may be used as long as a portion corresponding to the rotation shaft includes a vertical shaft connected to the upper link member and the lower link member. If the upper and lower connecting link member 50 is configured by a plate-like member in this way, it can be rotated by placing a hand anywhere on the free end side, and the operation can be performed in the same manner as when the operation unit 70 is enlarged. It is even easier.

  In each of the above-described embodiments, the operation lever 41 is formed by attaching the holder 40 to the separately formed operation lever main body 34. However, the operation lever 41 in the present invention may be integrated from the time of molding.
