摘要： An object is to provide a key protection structure for an electronic apparatus which can prevent a preset value of a switch from being intentionally changed by the user or the like. When setting of a first switch 21 is ended, a tool shutter operation portion 72 of a lock key 70 is inserted into a first shutter operation hole 61. The tool shutter operation portion 72 is then engaged with an engaging recess 45 of a first shutter 40. Thereafter, the lock key 70 is rotated, so that the first shutter 40 is rotated. A covering portion 44 of the shutter is therefore moved immediately above the first switch 21 to close a first switch operation hole 58, whereby the first switch 21 can be locked (key-protected) so as not to be externally operated.
