  In the substrate fixing jig of Patent Document 1, when adjusting the position of the member that holds the circuit board, for example, an operation of loosening and tightening eight screws (a total of 16 operations) is required.

  In the substrate fixing jigs of Patent Document 2 and Patent Document 3, when adjusting the position of the member that holds the circuit board, the screw is rotated, moved on the rail, and when the member is fixed, the same applies. It is necessary to lock the screw by rotating it.

  In the substrate fixing jig of Patent Document 4, when adjusting the position of the member that holds the circuit board, hold the stopper pin, pull it up, pull out the tip of the stopper pin from the stopper hole, and in that state the holding member Is moved along the longitudinal member, the tip of the stopper pin is aligned with one of several stopper holes provided at intervals in the longitudinal member, and the tip of the stopper pin is inserted into the hole. The work of inserting is necessary.

  Further, in the board fixing jig, stability of sliding movement of a member that holds the circuit board is required from the viewpoint of workability and the accuracy of position adjustment.

  An object of the present invention is to provide a substrate fixing jig that can adjust the position of a member that holds a substrate in a short time by a simple operation and that is excellent in the stability of sliding movement of the member.

  The present invention is a substrate fixing jig for fixing a substrate. The substrate fixing jig includes a guide member, a slide member, and an operation member. The guide member has guide teeth and extends in one direction. The slide member is movable in the slide direction along the guide member. The slide member has a pair of outer surfaces facing one side and the other side in the slide direction. The operation member has a pair of inner side surfaces opposed to the pair of outer side surfaces. The operation member is a member for moving the slide member in the slide direction. The operating member has lock teeth. The operation member is biased in an engagement direction in which the lock teeth and the guide teeth are engaged. The operation member is pressed in a direction opposite to the engagement direction, and a locked state in which movement of the slide member with respect to the guide member is restricted by engagement of the lock teeth and the guide teeth. It is configured to be switchable between an unlocked state in which the slide member can be moved relative to the guide member.

  In this configuration, the slide member has a pair of outer surfaces facing one side and the other in the sliding direction, and the operation member has a pair of inner surfaces facing the pair of outer surfaces. Therefore, when the operator moves the operation member to one side in the slide direction, the outer surface of the slide member facing the inner surface is pushed by the inner surface of the operation member. Similarly, when the operator moves the operation member to the other side in the slide direction, the outer surface of the slide member facing the inner surface is pushed by the inner surface of the operation member. That is, in this configuration, the direction in which the operation member slides and the direction of the outer surface of the slide member pressed by the inner surface of the operation member coincide with each other in terms of the slide direction. Excellent stability.

  In this configuration, the operator can switch the locked state to the unlocked state by pressing the operation member in the direction opposite to the engaging direction. In the unlocked state, the slide member can be moved relative to the guide member. Therefore, the operator moves the operating member to one side or the other side in the sliding direction while pressing the operating member in the direction opposite to the engaging direction, and when the sliding member reaches a desired position, Is stopped, and the pressing of the operating member is released (the hand is released from the operating member). As a result, the operation member is biased in the engagement direction, and the lock teeth of the operation member are engaged with the guide teeth of the guide member, and the unlocked state is switched to the locked state. Thus, in this configuration, the position of the member holding the substrate can be adjusted in a short time by a simple operation of pressing the operating member, sliding the operating member, and releasing the pressing of the operating member in this order, As described above, the stability during movement of the slide member is excellent.

  The substrate fixing jig preferably includes a blocking mechanism that prevents the locked state from being switched to the unlocked state.

  With this configuration, it is possible to prevent the operation member from being switched from the locked state to the unlocked state when the operator does not intend.

  In the substrate fixing jig, the slide member is fitted to the guide member so as to surround the guide member, and the guide teeth of the guide member can be engaged with the lock teeth of the operation member. It is preferable that it is partially opened.

  In this configuration, since the slide member is fitted to the guide member so as to surround the guide member, the stability when the slide member slides relative to the guide member is further improved. In addition, since the slide member does not surround the entire guide member but is partially opened, the guide teeth of the guide member can be engaged with the lock teeth of the operation member at the opened portion.

  In the substrate fixing jig, the slide member may have a support portion that supports the substrate.

  In this configuration, the support portion of the slide member can support the edge portion of the substrate, for example.

  In the substrate fixing jig, the slide member has a pair of insertion portions that are arranged in parallel in the sliding direction and through which the guide member is inserted, and the guide teeth and the lock teeth are formed of the pair of insertion portions. It is preferred to engage between.

  In this configuration, the guide member is inserted into the first insertion portion and the second insertion portion, and the guide teeth of the guide member engage with the lock teeth of the operation member between these insertion portions. That is, the movement of the lock teeth of the operation member in the engagement direction and the movement of the lock teeth of the operation member in the direction opposite to the engagement direction are in a well-balanced position between the first insertion portion and the second insertion portion. Since it is performed at a position where the deviation in the sliding direction is small, the engagement and disengagement operations of the guide teeth and the lock teeth are more stable.

  In the substrate fixing jig, the guide member extends in the sliding direction, the guide teeth are provided along the sliding direction, and an engagement rail that engages with the lock teeth, and is parallel to the engagement rail. And a guide rail that is arranged in a posture and guides the slide member.

  In this configuration, the guide member has two parts, an engagement rail and a guide rail. The engagement rail having the guide teeth has a function of engaging with the lock teeth of the operation member, and the guide rail has a function of guiding the slide member. These engagement rails and guide rails may be formed integrally or may be formed separately.

  In the substrate fixing jig, the width of the guide rail is preferably larger than the width of the engagement rail.

  In this configuration, it is possible to further improve the stability when the slide member slides along the guide member while adapting the shape and size of the guide tooth to the shape and size of the lock tooth. Specifically, it is as follows. That is, since the guide teeth of the guide member need to be engaged with the lock teeth of the operation member, the guide teeth are formed to match the shape and size of the lock teeth. That is, the guide teeth are restricted by the shape and size of the lock teeth. Therefore, in this configuration, the two functions described above are assigned to different parts, and the width of the guide rail that is not restricted by the shape and size of the lock teeth is made larger than the width of the engagement rail. Thus, by ensuring the width of the guide rail to some extent, the facing area (or contact area) between the guide rail and the slide member can be increased. Thereby, stability when the slide member slides along the guide member is further improved. Specifically, for example, when the slide member is fitted to the guide rail so as to surround the guide rail, the outer peripheral surface of the guide rail of the guide member and the inner peripheral surface of the fitting portion of the slide member The opposing area (or contact area) can be increased. Thereby, stability when the slide member slides along the guide member is further improved.

  In the substrate fixing jig, it is preferable that the guide rail has a groove extending along the sliding direction, and a part of the engagement rail is disposed in the groove.

  In this configuration, a part of the engagement rail is disposed in the groove of the guide rail. In other words, in this configuration, since a part of the engagement rail is fitted in the groove of the guide rail, the thickness of the guide member can be reduced compared to the case where the groove is not provided. In addition, the engagement rail is less likely to be displaced with respect to the guide rail.

  In the substrate fixing jig, the slide member may be in contact with the guide rail while being separated from the engagement rail.

  In this configuration, since the slide member is in contact with the guide rail, it is excellent in stability when the slide member slides with respect to the guide rail. Further, since the slide member is separated from the engagement rail, it does not interfere with the engagement between the lock teeth and the guide teeth. Thereby, since the engagement area (contact area at the time of engagement) of a lock tooth and a guide tooth can be enlarged, a locked state is stabilized. Thus, with this configuration, it is possible to achieve both stability during sliding movement and stability in the locked state.

  It is preferable that the substrate fixing jig includes a rotating portion that rotates the engagement rail about an axis, and the guide teeth are screw grooves provided in a spiral shape on the outer peripheral surface of the engagement rail. In this case, the position of the operating member in the sliding direction can be finely adjusted by rotating the engagement rail by the rotating portion in the locked state.

  In the substrate fixing jig, it is preferable that the slide member is configured by combining at least two members, and the at least two members are fixed to each other at least at four locations. When the slide member is configured by combining at least two members, these members are fixed at at least four locations, so that the fixed state of each other is stabilized. In addition, by providing at least four fixing points, it is possible to make an equal arrangement in which the four fixing points are arranged at positions corresponding to, for example, four corners of a rectangle. As a result, the stability of the entire slide member during sliding movement is further improved.

  The substrate fixing jig includes an auxiliary guide member disposed in a position parallel to the guide member at a position away from the guide member, and an auxiliary slide member that moves in the sliding direction along the auxiliary guide member. A bridging member that connects the slide member and the auxiliary slide member may be provided.

  In this configuration, as the slide member moves in the slide direction, the auxiliary slide member connected by the bridging member can also be moved together in the slide direction. In this configuration, the bridging member can also be used as a guide member. In this case, the bridging member as the guide member is provided with one or a plurality of slide members and a corresponding operation member.

  In the substrate fixing jig, the auxiliary slide member is preferably movable with respect to the auxiliary guide member.

  In this configuration, the operator can move the slide member, the auxiliary slide member, and the bridging member connecting them in the slide direction by operating only the operation member without gripping the auxiliary slide member. That is, the operator can move the slide member, the auxiliary slide member, and the bridging member in the slide direction by moving the operation member in the slide direction while pressing the operation member in the direction opposite to the engagement direction. In this way, when operating by holding only the operation member without gripping the auxiliary slide member, the engagement rail as described above is fixed to the guide rail at at least four locations, It is preferable to adopt a structure with improved stability during slide movement. Thereby, even if it is operation of only one side which operates only an operation member, the slide movement of a slide member does not become unstable easily.

[Summary of Embodiment]
In the present embodiment, the slide member 3 has a pair of outer surfaces facing one and the other in the sliding direction, and the operation member 4 has a pair of inner surfaces facing the pair of outer surfaces. Therefore, when the operator moves the operation member 4 to one side in the slide direction, the outer surface of the slide member 3 facing the inner surface in the slide direction is pushed by the inner surface of the operation member 4. Similarly, when the operator moves the operation member 4 to the other side in the slide direction, the outer surface of the slide member 3 facing the inner surface in the slide direction is pushed by the inner surface of the operation member 4. In other words, in this configuration, the direction in which the operation member 4 slides and the direction of the outer surface of the slide member 3 pushed by the inner surface of the operation member 4 coincide with each other in terms of the slide direction. The stability when moving is excellent.

  In the present embodiment, the operator can switch the locked state to the unlocked state by pressing the operation member 4 in the direction opposite to the engaging direction. In the unlocked state, the slide member 3 can be moved relative to the guide member 2. Therefore, the operator moves the operating member 4 to one side or the other side in the sliding direction while pressing the operating member 4 in the direction opposite to the engaging direction, and the slide member 3 reaches a desired position. Then, the operation member 4 is stopped and the pressing of the operation member 4 is released (the hand is released from the operation member 4). As a result, the operation member 4 is biased in the engaging direction, the lock teeth T2 of the operation member 4 engage with the guide teeth T1 of the guide member 2, and the unlocked state is switched to the locked state. As described above, in this configuration, the position of the member holding the substrate can be adjusted in a short time by a simple operation of pressing the operating member 4, sliding the operating member 4, and releasing the pressing of the operating member 4 in this order. Moreover, as described above, the stability during movement of the slide member 3 is excellent.

  In this embodiment, the substrate fixing jig includes a blocking mechanism that prevents the locked state from being switched to the unlocked state. With this configuration, it is possible to prevent the operation member 4 from being switched from the locked state to the unlocked state when the operator does not intend.

  In this embodiment, the slide member 3 is fitted to the guide member 2 so as to surround the guide member 2 and the guide teeth T1 of the guide member 2 can be engaged with the lock teeth T2 of the operation member 4. Is partially open. In this configuration, since the slide member 3 is fitted to the guide member 2 so as to surround the guide member 2, the stability when the slide member 3 slides relative to the guide member 2 is further improved. Moreover, since the slide member 3 does not surround the entire guide member 2 but is partially opened, the guide tooth T1 of the guide member 2 engages with the lock tooth T2 of the operation member 4 in the opened portion. can do.

  In the present embodiment, the second slide member 3 has a pair of insertion portions that are juxtaposed in the sliding direction and through which the guide member 2 is inserted, and the guide teeth T1 and the lock teeth T2 are between the pair of insertion portions. Engage. In this configuration, the guide member 2 is inserted into the first insertion portion and the second insertion portion, and the guide teeth T1 of the guide member 2 are engaged with the lock teeth T2 of the operation member 4 between these insertion portions. That is, the movement of the lock tooth T2 of the operation member 4 in the engagement direction and the movement of the lock tooth T2 of the operation member 4 in the direction opposite to the engagement direction are referred to as between the first insertion portion and the second insertion portion. Since it is performed at a well-balanced position (a position where there is little deviation in the sliding direction), the engagement and disengagement operations of the guide teeth T1 and the lock teeth T2 are more stable.

  In this embodiment, the guide member 2 extends in the sliding direction, is provided with guide teeth T1 along the sliding direction, and is arranged in an attitude parallel to the engaging rails, the engaging rails with which the locking teeth T2 are engaged, And a guide rail for guiding the slide member 3. In this configuration, the guide member 2 has two parts, that is, an engagement rail and a guide rail. The engagement rail having the guide teeth T1 has a function of engaging with the lock teeth T2 of the operation member 4, and the guide rail has a function of guiding the slide member 3. These engagement rails and guide rails may be formed integrally or may be formed separately.

  In this embodiment, the width of the guide rail is larger than the width of the engagement rail. In this configuration, it is possible to further improve the stability when the slide member 3 slides along the guide member 2 while adapting the shape and size of the guide tooth T1 to the shape and size of the lock tooth T2. .

  In this embodiment, the guide rail has a groove extending along the sliding direction, and a part of the engagement rail is disposed in the groove. In this configuration, a part of the engagement rail is disposed in the groove of the guide rail. In other words, in this configuration, since a part of the engagement rail is fitted in the groove of the guide rail, the thickness of the guide member 2 can be reduced as compared with the case where the groove is not provided. In addition, the engagement rail is less likely to be displaced with respect to the guide rail.

  In the present embodiment, the slide member 3 is in contact with the guide rail, but is separated from the engagement rail. In this configuration, since the slide member 3 is in contact with the guide rail, the slide member 3 is excellent in stability when the slide member 3 slides relative to the guide rail. Further, since the slide member 3 is separated from the engagement rail, it does not interfere with the engagement between the lock teeth T2 and the guide teeth T1. Thereby, since the engagement area (contact area at the time of engagement) of the lock teeth T2 and the guide teeth T1 can be increased, the lock state is stabilized. Thus, with this configuration, it is possible to achieve both stability during sliding movement and stability in the locked state.

  In the present embodiment, the board fixing jig includes a rotating portion that rotates the engagement rail around the axis, and the guide teeth T1 are screw grooves provided in a spiral shape on the outer peripheral surface of the engagement rail. In this case, the position of the operation member 4 in the sliding direction can be finely adjusted by rotating the engagement rail by the rotating portion in the locked state.

  In the present embodiment, the slide member 3 is configured by combining at least two members, and the at least two members are fixed to each other at at least four locations. When the slide member 3 is configured by combining at least two members, these members are fixed at at least four locations, thereby stabilizing each other's fixed state. In addition, by providing at least four fixing points, it is possible to make an equal arrangement in which the four fixing points are arranged at positions corresponding to, for example, four corners of a rectangle. As a result, the stability of the entire slide member 3 during sliding movement is further improved.

  In the present embodiment, the substrate fixing jig moves in the sliding direction along the auxiliary guide member 7 disposed in a position parallel to the guide member 2 at a position away from the guide member 2. The auxiliary slide member 8 and a bridging member that connects the slide member 3 and the auxiliary slide member 8 are provided. In this configuration, as the slide member 3 moves in the slide direction, the auxiliary slide member 8 connected by the bridging member can also be moved together in the slide direction. In this configuration, a bridging member can also be used as the guide member 2. In this case, the bridging member as the guide member 2 is provided with one or a plurality of slide members 3 and an operation member 4 corresponding thereto.

  In the present embodiment, the auxiliary slide member 8 is movable with respect to the auxiliary guide member. In this configuration, the operator moves the slide member 3, the auxiliary slide member 8, and the bridging member connecting them in the slide direction only by operating the operation member 4 without holding the auxiliary slide member 8. be able to. That is, the operator moves the slide member 3, the auxiliary slide member 8, and the bridging member in the slide direction by moving the operation member 4 in the slide direction while pressing the operation member 4 in the direction opposite to the engagement direction. be able to. As described above, when the operation is performed by holding only the operation member 4 without gripping the auxiliary slide member 8, the engagement rail as described above is fixed to the guide rail in at least four places, and the slide member It is preferable to adopt a structure in which the stability of the entire three slides is improved. Thereby, even if it is operation of only one side which operates only the operation member 4, the slide movement of the slide member 3 does not become unstable easily.
