PURPOSE:To improve the adjustment precision of a switch and to miniaturize and mass-produce a detector by providing the switch, which converts the vertical bend due to an external force of a disk case by a lever and detects it, near a disk case insertion entrance. CONSTITUTION:A switch 204 which converts the vertical bend due to external forces Y1 and Y2 of a disk case 102 by switch levers 201 and 202 and detects it is provided near the disk case insertion entrance. Thus, the space is effectively used. An external detecting switch adjustment pin 207 which is an eccentric pin is turnably caulked, and the outside of the adjustment pin is brought into contact with the externals force detecting switch 204 by turning of the adjustment pin in the direction of an arrow u1(w1) or u2(w2) to operate it in the direction of the arrow u1 or u2, thus subtly adjusting turning-ON/OFF of the external force detecting switch 204.
