ABSTRACT:
A safety bar mechanism and sheet processing device having a safety bar mechanism, with which such an accident that the operator's hand is pinched between a table and peripheral devices etc. can be positively avoided whatever direction an external force exerts. The safety bar mechanism is disposed, for example, above the table on which a sheet is stacked, and comprises detector means the upper end of which is supported on a fixed part such that the detector means pivots freely in forward/backward directions and has play in upward/downward directions. When an external force works on the detector means, thereby moving the detector means upwards, forwards or backwards, a switching means is so operated as to at least stop the upward movement of the table.
