Claims

[Scope of utility model registration request]

A numeric keypad switch for inputting a password, a central processing unit, an electromagnetic solenoid for unlocking by inputting the numeric keypad switch, a piezoelectric buzzer, and a power source for supplying power to the central processing unit, solenoid, etc. , a non-volatile memory that stores the password set by the ten-key switch; a substantially L-shaped sliding body that also serves as an operating lever; and a sliding body that is slidably engaged with the sliding body through a groove. An interlocking mechanism having a locking recess that locks a locking protrusion erected on a part of the sliding body and an engaging protrusion erected on a part of the sliding body, respectively, symmetrically with respect to a rotation axis. a plate, a locking mechanism in which a latch can be protruded and retracted by operating the electromagnetic solenoid, and a casing that operable houses each of the constituent members;
a pull recess formed in a part of the casing and from which the operating lever slidably protrudes, a part of which is locked to a part of the casing, and the other end of which is locked to a part of the sliding body; A sliding body and a portion of the sliding rod include a spring that biases the casing in a direction to protrude, a cover plate that covers the opening of the casing, and a decorative plate that further covers the top of the cover plate, and the numeric keypad. An electromagnetic lock characterized in that a password set by a switch is retained in the nonvolatile memory even after the power is turned off.
