A work reversing apparatus which transports a work processed by a press machine comprising: a first conveyor having a first transporting surface which transports a work; a second conveyor having a second transporting surface which transports a work; a first holding unit which holds a work on the first transporting surface; a second holding unit which holds a work on the second transporting surface; a rotary driving unit which integrally rotates the first conveyor and the second conveyor; and a controller which controls driving of the rotary driving unit, the first holding unit being able to hold a work on the first transporting surface independently from the second holding unit, the second holding unit being able to hold a work on the second transporting surface independently from the first holding unit, the first transporting surface being disposed to face the second transporting surface, the first transporting surface and the second transporting surface being able to hold works regardless of the directions of the first conveyor and the second conveyor during the rotation, the controller being configured to drive the rotary driving unit such that when the rotary driving unit rotates the first conveyor and the second conveyor, the second transporting surface moving to a position where the first transporting surface has been located immediately before the rotation, the first transporting surface moving to a position where the second transporting surface has been located immediately before the rotation, a work being carried out, immediately after the rotation, to a downstream side in a transporting direction of the work from one of the first transporting surface and the second transporting surface to which the work has been carried in from an upstream side in the transporting direction immediately before the rotation, and a work being carried in, immediately after the rotation, from the upstream side in the transporting direction to the other transporting surface (31, 21) from which a work has been carried out to the downstream side in the transporting direction immediately before the rotation, characterized in that the first conveyor including a first guide provided between the first and second transporting surfaces (21, 31) and extending in a direction parallel with the first transporting surface and the second transporting surface, the second conveyor including a second guide provided between the second transporting surface and the first transporting surface and extending in a direction parallel with the second and first transporting surfaces (31, 21). a first conveyor having a first transporting surface which transports a work;
