2. Description of the Related Art As the above-mentioned board supporting apparatus, there is known a board supporting apparatus having a guide member formed with guide grooves into which both ends of a printed wiring board are inserted. In a board supporting device of this type, when inserting a board in an upright state, a guide rail having a U-shaped groove is provided at an upper portion and a lower portion as a guide member, and an upper end and a lower end of the board are aligned with the guide rail. Inserted.

Problems to be Solved by the Invention However, it is difficult to guide the surface of the board to be inserted in sliding contact with components and the like installed on the board. For this reason, the insertion of the upper end and the lower end in alignment with the U-groove needs to be performed very carefully, and there is a problem that operability is poor.

When the board supporting device is a controller rack of a laser printer, as shown in FIG. 11, the width a1 of the insertion end side of the controller board 50 is shorter than the width a2 of the rear side due to the compactness of the printer body 40.

The upper and lower guide rails 4 having U grooves as shown in FIG.
The following problems occurred in the board support device equipped with 1,42.

For a while after the insertion of the controller board 50 is started, as shown in FIG. 12, the upper end of the controller board 50 forms an inclined portion, and cannot be supported by the upper guide rail 41. For this reason, the controller board 50 may be inserted while being swung right and left. There was a danger that the parts that were used could be damaged. Particularly, in the case of the controller board 50 of the printer, it is conceivable that the user of the printer attaches and detaches the controller board 50, and it is expected that the frequency of this danger will be much higher than that of other boards.

Further, when the upper end of the controller board 50 starts to be supported by the upper guide rail 41, since the tip of the controller board 50 has entered the interior of the printer body 40 considerably, the controller board 50 is inserted into the U groove of the upper guide rail 41.
I can't visually confirm that the top of has entered. Therefore, in the case of the controller board 50 in which the inclined portion is formed on the upper end side, the insertion operability is extremely deteriorated.
