a display device-side connector configured to form a first electrical connection with a first apparatus-side connector of a first endoscopic apparatus, wherein the first endoscopic apparatus comprises:

a first mechanism for performing a first function; and

a first endoscopic apparatus-side battery for powering the first mechanism to perform the first function; and

a processor comprising hardware, the processor being configured to:

control discharging of the display device-side battery through the first electrical connection between the display device-side connector and the first apparatus-side connector of the first endoscopic apparatus to charge the first endoscopic apparatus-side battery;

determine during charging of the first endoscopic apparatus-side battery whether a charging capacity of the first endoscopic apparatus-side battery is equal to or larger than a first predetermined threshold; and

stop charging of the first endoscopic apparatus-side battery when the processor determines that the charging capacity of the first endoscopic apparatus-side battery is equal to or larger than the first predetermined threshold.

2. The endoscope system according to claim 1 , wherein

the display device includes a locking section, and

a section to be locked configured to engage with the locking section in common is disposed in each of the placing sections.

3. The endoscope system according to claim 2 , wherein

one of the plural apparatus bodies is an endoscope apparatus having a bending section, and

the display device is set on the placing section of the endoscope apparatus with an angle, the angle of a monitor screen of the display device and a monitor placing surface in the placing section of the endoscope apparatus being different from an angle of the monitor screen at the time the display device is placed on the placing section of another apparatus of the apparatuses and a monitor placing surface in the placing section of the other apparatus.

4. The endoscope system according to claim 2 , wherein, up, down, left, and right directions of the monitor screen of the display device with respect to the plural apparatuses are defined by engagement of the locking section and the section to be locked.

5. The endoscope system according to claim 1 , wherein a width dimension of the display device is larger than a width dimension of the placing sections.

6. The endoscope system according to claim 1 , further comprising: a first memory disposed in the display device and configured to store image data; and a second memory disposed in each of the plural apparatuses and configured to store the image data.

7. The endoscope system according to claim 1 , wherein each of the plural apparatuses includes an individual identification component with which the display device recognizes individual information when the display device is set on the placing section.

8. The endoscope system according to claim 1 , further comprising a data converting section disposed in the display device and configured to convert image data into an image size optimum for the monitor screen mounted on the display device and output the image data.

9. The endoscope system according to claim 1 , further comprising data converting sections disposed in the plural apparatuses and configured to convert image data into an image size optimum for the monitor screen mounted on the display device and output the image data.

10. The endoscope system according to claim 1 ,

wherein the display device-side connector is further configured to form a second electrical connection with a second apparatus-side connector of a second endoscopic apparatus, wherein the second endoscopic apparatus comprises:

a second mechanism for performing a second function; and

a second endoscopic apparatus-side battery for powering the second mechanism to perform the second function, and

wherein the processor is further configured to control discharging of the display device-side battery through the second electrical connection between the display device-side connector and the second apparatus-side connector of the second endoscopic apparatus to charge the second endoscopic apparatus-side battery.

11. The endoscope system according to claim 10 , further comprising the first endoscopic apparatus and the second endoscopic apparatus.

12. The endoscopic system according to claim 11 ,

wherein the first endoscopic apparatus is one of a flexible endoscope and a rigid endoscope, and

wherein the second endoscopic apparatus is the other of the flexible endoscope and the rigid endoscope.

13. The endoscope system according to claim 1 ,

wherein the display device-side connector is further configured to form a charging electrical connection with a holder-side connector of a holder, wherein the holder comprises an adapter connected to a power supply, and

wherein the processor is further configured to control charging of the display device-side battery by the power supply through the charging electrical connection between the display device-side connector and the holder-side connector.

14. The endoscopic system according to claim 13 , the processor is further configured to:

determine during the charging of the display device-side battery whether a charging capacity of the display device-side battery is equal to or larger than a second predetermined threshold; and

stop the charging of the display device-side battery when the processor determines that the charging capacity of the display device-side battery is equal to or larger than the second threshold.
