the wireless tag reader further includes a controller configured to control the emission of the radio wave according to an operation of the trigger switch.

3. The reading apparatus according to claim 2 , wherein

the wireless tag reader further includes a sensor, and

the controller is further configured to detect the connection between the wireless tag reader and the grip using an output from the sensor.

4. The reading apparatus according to claim 3 , wherein

a magnet is attached to the trigger switch of the grip,

the sensor of the wireless tag reader is a magnetic sensor configured to detect a magnetic flux density, and

the controller detects the connection based on the detected magnetic flux density.

5. The reading apparatus according to claim 4 , wherein the controller is further configured to detect whether the trigger switch is operated based on the detected magnetic flux density.

6. The reading apparatus according to claim 1 , wherein the wireless tag reader further includes:

a network interface through which the tag information is output, and

a controller configured to switch output destinations of the tag information depending on whether the grip of the code reader is connected to the wireless tag reader.

7. The reading apparatus according to claim 6 , wherein

the wireless tag is attached to a commodity sold at a store, and

the tag information that is read from the wireless tag is output to either a point-of-sale terminal or an inventory management server.

8. The reading apparatus according to claim 1 , wherein the code reader further includes:

a network interface through which the code is output, and

a controller configured to switch output destinations of the code depending on whether the grip of the code reader is connected to the wireless tag reader.

9. The reading apparatus according to claim 8 , wherein

a symbol representing the code is indicated on a commodity sold at a store, and

the code that is read from the image of the symbol is output to either a POS terminal used at the store or an inventory management server for managing an inventory of the store.

10. The reading apparatus according to claim 1 , wherein

a convex portion is formed at an end of the grip of the code reader, and

the wireless tag reader includes a support portion that protrudes towards a direction opposite to the first direction and has a groove into which the convex portion of the grip is inserted.

11. The reading apparatus according to claim 10 , wherein

a retractable claw is formed on an outer surface of the convex portion, and

the groove has a recessed portion that engages with the claw when the convex portion of the grip is inserted into the groove.

12. The reading apparatus according to claim 11 , wherein the grip includes a sliding switch for locking the claw at a position at which the claw protrudes from the outer surface of the convex portion.

13. The reading apparatus according to claim 1 , wherein the code reader further includes:

a retractable switch formed on the grip and protruding towards the first direction, and

a controller configured to detect the connection with the wireless tag reader based on whether the switch is retracted.

14. The reading apparatus according to claim 1 , further comprising:

an information terminal configured to receive the tag information read by the wireless tag reader and the code read by the code reader.

15. The reading apparatus according to claim 14 , wherein the information terminal includes a display configured to display the received tag information and code.

16. A wireless tag reader, comprising:

an antenna by which a radio wave is emitted to read tag information from a wireless tag;

a main body including a first surface facing a first direction and through which the antenna emits the radio wave; and

a support portion protruding from the main body towards a direction opposite to the first direction and having a groove into which a grip of an optical code reader can be inserted.

17. The wireless tag reader according to claim 16 , further comprising:

a controller configured to control the emission of the radio wave according to an operation of a trigger switch attached to the grip of the code reader.

18. The wireless tag reader according to claim 17 , further comprising:

a sensor, wherein

the controller is further configured to detect the connection between the wireless tag reader and the grip using an output from the sensor.

19. A code reader, comprising:

an imaging unit configured to acquire an image to read a code;

an imaging window facing a first direction and through which the imaging unit acquires the image; and

a grip connectable to a groove of a wireless tag reader configured to emit a radio wave to read tag information from a wireless tag through a first surface facing the first direction.

20. The code reader according to claim 19 , wherein

the grip includes a trigger switch for causing the imaging unit to acquire an image, and

the emission of the radio wave by the wireless tag reader is controlled according to an operation of the trigger switch.
