Abstract: A syringe drive device 1 includes: a syringe holding section 3; a piston manipulating section 4; and a display section 6. An outer tube 202 of a syringe 201 is detachably held by the syringe holding section 3. A piston 203 of the syringe 201 is detachably engaged with the piston manipulating section 4. The piston manipulating section 4 moves in a direction in response to an operation of operation buttons 8A and 8B, and the piston 203 is thereby moved in a direction where the piston is pushed into or pulled out from the outer tube 202. An internal pressure of a medicinal solution container punctured with an injection needle 204 attached to the outer tube 202 of the syringe 201 is measured and displayed on the display section 6.

The transmission control mechanism unlocks the follower gear from the drive gear in response to detection, by the collision detection unit, of a collision between the arm and the obstacle. The robot arm enables quick cushioning of the impact force of the collision.
