い。According to the configuration of the present invention, the printed circuit board fixing base can be easily attached, and at the same time, the printed circuit board fixing base is hardly detached from the instrument body by mounting the printed circuit board. That is, since the lamp holder mounting notch, the heat radiation hole, and the connector mounting hole are lined up in a substantially straight line portion of the printed circuit board fixing base, the printed circuit board fixing base can be mounted without increasing the number of processing of the printed circuit board fixing base. It becomes easier to bend in a direction orthogonal to the substantially straight line. Therefore, if the mounting claws are provided on both ends in the orthogonal direction so that the hooks face the opposite sides, even if the mounting claws are hard, the printed circuit board fixing base is elastically deformed by pushing the center part of the printed circuit board fixing base. The mounting claws can be deformed to easily lock the mounted portion without applying excessive force. Also, the mounting claw may be short because it is elastically deformed together with the printed circuit board fixing base itself when mounting the printed circuit board fixing base itself. Therefore, the stacking direction of the instrument body, the printed circuit board fixing base and the printed circuit board should be set to the minimum height. be able to. Further, when the printed circuit board is mounted on the printed circuit board fixing base, the deformation direction of the printed circuit board fixing base caused by the deformation of the locking claws is the direction to strengthen the mounting of the printed circuit board fixing base to the instrument body. There is no danger that the board fixing base will come off.

れるおそれがない。According to this embodiment, the lamp holder mounting notch 3 and the heat dissipation hole 4 are provided in the portion of the printed circuit board fixing base 1 on the substantially straight line A.
Since the connector mounting holes 5 are arranged side by side, the printed board fixing base 1 can be easily bent in the direction B orthogonal to the straight line A without increasing the number of processing of the printed board fixing base 1. Therefore, if the mounting claws 7 are provided so that the hook portions 6 face the opposite ends of the both ends in the orthogonal direction B, the printed circuit board is fixed by pushing the central part of the printed circuit board fixing base 1 even if the mounting claws 7 are hard. The table 1 can be elastically deformed to deform the attachment claws 7 and easily locked without applying excessive force to the attached portion 8. Further, since the printed board fixing base 1 itself is elastically deformed when the printed board fixing base 1 itself is mounted, the mounting claw 7 may be short. Therefore, the stacking direction of the device main body 2, the printed circuit board fixing base 1 and the printed circuit board 10 may be changed. It can be at a minimum height. Further, when mounting the printed circuit board 10 on the printed circuit board fixing base 1, the locking claw 9
The deformation direction of the printed circuit board fixing base 1 caused by the deformation is a direction in which the mounting of the printed circuit board fixing base 1 to the instrument body 2 is made firm, so that the printed circuit board fixing base 1 does not come off.
なお、プリント基板固定台１をより強固に固定する場
合には、ガイド用ボス13,14が熱溶着される。When the printed circuit board fixing base 1 is fixed more firmly, the guide bosses 13 and 14 are heat-welded.

リント基板固定台が外れるおそれがない。According to the mounting structure of the printed circuit board fixing base of this invention,
Since the lamp holder mounting notch, the heat dissipation hole and the connector mounting hole are arranged in a line on the straight line of the printed circuit board fixing base, the printed circuit board fixing base can be roughly straightened without increasing the processing drawing of the printed circuit board fixing base. It becomes easier to bend in the direction orthogonal to the line. Therefore, if the mounting claws are provided on both ends in the orthogonal direction so that the hooks face toward the opposite sides, even if the mounting claws are hard, the printed circuit board fixing base is elastically deformed by pushing the center part of the printed circuit board fixing base. The mounting claws can be deformed to easily lock the mounted portion without applying excessive force. Also, the mounting claw may be short because it is elastically deformed together with the printed circuit board fixing base itself when mounting the printed circuit board fixing base itself. Therefore, the stacking direction of the instrument body, the printed circuit board fixing base and the printed circuit board should be set to the minimum height. be able to. Further, when the printed circuit board is mounted on the printed circuit board fixing base, the deformation direction of the printed circuit board fixing base caused by the deformation of the locking claws is the direction to strengthen the mounting of the printed circuit board fixing base to the instrument body. There is no danger that the board fixing base will come off.

ント基板固定台が器具本体から外れにくくなるという効
果がある。Therefore, the printed circuit board fixing base can be easily attached, and at the same time, by mounting the printed circuit board fixing base, the printed circuit board fixing base is less likely to come off from the instrument body.
