摘要：PURPOSE:To improve the production yield of indicators by providing edges projecting approximately in vertical against an indication face at the circumference of a recess in a dish shaped glass container constituting a photoconductive member thereby eliminating the working defect, insufficient seal, etc. CONSTITUTION:Indicating window or a dish shaped glass container 11 is comprised of a recess 12 inserted with an insulation board 24 having numbers, symbols and character electrodes 23 composed of a plurality of cathode elements 22a-22h representing a portion or entire outline of numbers, symbols and characters as indicating electrodes 21 when performing the embossing while using a glass plate cut in flat and rectangular, and a circumferential section 13 having predetermined width W required for sealing around the circumference of said recess 12. Projected edges 15 are formed at the outer circumference of said section 13 while having such shape as it is bent in perpendicularly, acute or obtuse in same direction with the forming direction and have width W sufficiently narrow against the width W of said section 13. Consequently the production yield can be improved.
