Kind Code:

Abstract:
PURPOSE:To stably obtain a preassembly state by forming a space for slide to permit the slide of an erroneous erasing preventing valve above a linked part between an inner deep wall and a coupling boss. CONSTITUTION:An inner deep wall 13 of an erroneous erasing preventing hole 11 in a lower case 1b is provided close to an inner direction rather than a rear wall 10a of an upper case 1a and the erroneous erasing preventing valve 12 is equipped with a main wall 15, to which a detecting member P on the recorder side is operated, and a hook-shaped lock arm 16, which is protruded from this main wall 15 to the inner direction, with a downward bent tip 16a. The lock arm 16 of the preventing valve 12 is freely slid along the inner deep wall 13 over the upper end of the inner deep wall 13. On the inside of the inner deep wall 13 in the lower case 1b, a coupling boss 28 is provided to be coupled with the upper case 1a and this inner deep wall 13 is integrally linked through a linked part 31 to the root part of the coupling boss 28. Then, in the upper direction of the linked part 31 between the inner deep wall 13 and the coupling boss 28, a space 32 for slide is formed to permit the slide of the erroneous erasing preventing valve 12 and the stable preassembly state can be obtained.
