An endoscopy system includes a self-propelling endoscope attached with a self-propelling device, a drive source device for providing drive force to the self-propelling device, a controller connected to the drive source device and for controlling moving direction and speed of the self-propelling device, and a monitor for displaying a captured image. The drive source device transmits drive information such as forward movement, backward movement, stop, speed, load torque of the self-propelling device to a processing device. The processing device displays the drive information on the monitor with the captured image.
