2 is a side elevation view of a safety document separator formed in accordance with an embodiment of the present invention;
3 is an enlarged sectional view of a portion A of the operation control device of a safety document separator formed in one embodiment of the present invention.
4 is an operational conceptual cross-sectional view of an operation control device of a safety document separator formed as an embodiment of the present invention.

The present invention has a box-shaped case 10 in which a document inlet 11 is formed at an upper end thereof and a door is formed at a lower end thereof; A plurality of cutting blades are fixed to a pair of cutter shafts (22) at an inner upper end of the case (10), and are cut by a driving motor to cut a waste document drawn through the document inlet (11) (20); In a general document separator 30 formed at the lower end of the cutting device 20 and formed with a waste paper tray 30 for stacking the waste paper chips cut by the cutting device 20,

An operation control device 100 is formed at the lower end of the document input port 11. The operation control device 100 includes a body 11a having a lower end opened at the periphery of an opening 11a protruding into the document input port 11, A case 110 is formed in the body case 110 so that the stop bar 120 and the operation bar 122 correspond to each other in the body case 110. The stop bar 120 is attached to the side surface of the body case 110, And the solenoid switch 130 is formed to be able to operate by an open switch. The solenoid switch 130 is configured to be operated by an open switch.

The body case 110 of the operation control apparatus 100 is formed by inclining the bottom bottom from the both sides to the center, and a cut-out portion 102 formed at the center is formed.

The cut-out portion 102 is formed to have the same size as the opening 11a, so that the closed document passes through this portion.

The cutout portion 102 of the body case 110 is clogged by the stop bar 120 and the action bar 122 in the form of a circular bar. The stop bar 120 and the action bar 122 are both closed with the body case 110 and supported at the center by the inclination of the inner bottom.

The solenoid switch 130 is mounted on the side surface of the body case 110 so that the arm 132 is protruded or fixed by the electromagnet and can be released. So that the stop bar 120 or the operation bar 122 can be pushed.

The side where the solenoid switch 130 is not installed is formed to be pushed to one side by a spring projecting from the inside of the body case 110 on the side of the stop bar 120 or the operation bar 122.
