  In conventional baskets or storage jigs, it is necessary to insert the side portions of the plate-like held body between the side holding portions or into the holding grooves, and therefore, labor may be required for inserting the held body. That is, when the object to be held is thin and easily bent, or when the width is wide, it takes time to insert both side portions into the side holding portions or the holding groove at the same time, and labor is required for the insertion work. In particular, the insertion work becomes even more complicated when the side holding parts or the holding grooves are narrowly formed to prevent the holding object from shaking.

  Therefore, the present invention has been made in view of the above points, and an object of the present invention is to provide a basket that can reduce the labor of inserting the held object into the basket.

  In order to achieve the above object, the present invention provides a basket for holding a plurality of plate-like objects to be held at a distance from each other, and forming a space for holding the objects to be held. And the upper surface of the space is provided on the opposing side surface of the frame body, which is formed as an insertion port of the held body, and is spaced in the thickness direction of the held body inserted into the space. A plurality of side holders that can hold the side parts of the held object, and are arranged at intervals along the arrangement direction of the side holders, and inserted into the insertion port. And a plurality of guide portions having a shape capable of guiding the object to be held to the side portion holding portion.

  In the basket according to the present invention, when the object to be held is inserted into the side part holding part through the insertion port, the object to be held can be inserted into the side part holding part through the gap between the guide parts. For this reason, since the area | region through which a to-be-held body passes is controlled by a guide part, even when the to-be-held body is thin and easy to bend, or when the width is wide, the to-be-held body can be easily attached to the side holding section Can be inserted.

However, if the guide portion holding body opens the insertion port, the frame When the body to be held is taken out, the body to be held does not come into contact with the guide portion. For this reason, not only can the held body be easily taken out, but also the held body can be prevented from being damaged when taken out. In addition, a some guide part can be moved simultaneously by opening an insertion port with a guide part holding body.

  In this aspect, the guide holding body may be detachable from the frame. In this aspect, the insertion port is opened by removing the guide holder from the frame. Therefore, it is possible to easily take out the held body simply by removing the guide holding body.

  Moreover, the support part for supporting the said guide part holding body with respect to the said frame body may be provided in the said guide part holding body so that a clearance gap may be formed between the said frame bodies. In this aspect, since a gap is formed between the frame body and the guide holder, for example, when the basket is submerged in the liquid tank and then taken out from the tank, the liquid can be discharged through the gap. It becomes. Therefore, the efficiency of discharging the liquid from the basket can be improved.

  In this aspect, it is preferable that the support portion also functions as positioning means for the guide portion with respect to the side portion holding portion in the arrangement direction of the guide portions. In this aspect, since the positional relationship between the side portion holding portion and the guide portion is accurately determined in the direction in which the side portion holding portion and the guide portion are arranged, the guide portion is used to insert the held body into the frame body. The holding body can be smoothly inserted into the side holding portion.

  Furthermore, it is preferable that the guide part holding body is provided with a presser part capable of pressing the plurality of guide parts held by the side part holding part. In this aspect, since the to-be-held body inserted in the side part holding | maintenance part is pressed by the holding part, when a basket is immersed in a liquid tank, it can prevent that a to-be-held body floats.

  In the aspect in which the pressing portion is provided, the guide portion holding body is provided with a shaft portion, and the pressing portion has a pressing position at which the plurality of held bodies held by the side portion holding portion are pressed. Further, it may be configured to be rotatable around the shaft portion between the retracted position retracted from the presser position. In this aspect, the presser part can be moved between the presser position of the object to be held and the retracted position retracted therefrom only by rotating the presser part. Moreover, since the presser part is attached to the guide part holding body, the treatment of the presser part does not become troublesome when the held body is inserted.

  Further, it is preferable that a handle portion is provided in the presser portion. In this aspect, since the handle portion is provided in the pressing portion, the guide portion holding body can be moved using the pressing portion for pressing the held body.

It is located in the groove 39a, and thereby the engagement state between the distal end portion of the pressing portion 39 and the engagement pin 50 is released. In this state, the presser unit 39 is rotated to move from the presser position to the retracted position. As a result, the printed board P can be inserted between the guide portions 37 of the lid portion 14.

  Then, the printed board P is inserted into the gap between the adjacent guide parts 37 from above the lid part 14 and moved downward as it is, so that both sides of the printed board P are the side holding parts 23 of the frame 12. Is inserted into the holding groove 23a. Then, the printed circuit board P is further lowered, and the printed circuit board P can be inserted until the lower end portion of the printed circuit board P is inserted between the wall portions 28b of the bottom holding portion 25 and comes into contact with the support member 26. In this state, the printed board P is held, and at this time, the upper end portion Pa of the printed board P is sandwiched between the guide portions 37. This insertion operation is performed one by one, and when the predetermined number of printed circuit boards P have been inserted, the holding operation of the printed circuit board P is completed by returning the presser 39 to the press position again. In this state, the basket 10 is transported and sequentially passed through, for example, each step of the plating step. Even if there is a step of immersing the basket 10 in the liquid tank among these steps, since the printed circuit board P is pressed by the pressing portion 39, the lifting or the like is suppressed.

  After completing each process, the printed circuit board P is taken out from the basket 10 by the take-out device 60. In order to take out the printed circuit board P, the lid 14 is removed by the attaching / detaching mechanism 70. This removal procedure is the same as the procedure for attaching the lid 14.
