IMAGE PICKUP ELEMENT ASSEMBLING DEVICE FOR ENDOSCOPE

摘要

PROBLEM TO BE SOLVED: To accelerate the reduction in diameter by efficiently arranging signal lines in the space on the outer peripheral side within the front end of an endoscope even when circuit boards are arranged on the outer peripheral side. SOLUTION: Two sheets of the upper and lower circuit boards 11 and 12 are arranged above and below a CCD 1 and the lead wires 2 of the CCD 1 are connected to front surface side terminal pads Kc of these circuit boards 11 and 12. The rear side is provided with plural rows of terminal pads Kd for connecting the signal lines 14. The number in the endoscope axis direction 100 of the terminal pads Kd is set so as to be larger as the spacings D between the circuit boards 11 and 12 and the arcuate inside wall of a cylindrical supporting body 16 are greater. The circuit boards 11 and 12 are arranged by bending the circuit boards approximately 90 deg. after the connection of the CCD 1. As a result, the effective utilization of the inside wall side spacing of the supporting body 16 is made possible. The terminal pads may be formed with inclination.
