When the speaker 22 detects the presence of the mobile phone via the antenna 15 and reads the recorded information (or writes information), the speaker 22 emits a predetermined sound and reads the information (or To write to the user.

  In the ROM 23, a processing program for the CPU 20 is recorded in advance. In this embodiment, a processing program for changing the vertical direction of the image 11a displayed on the display 11 when the reader / writer body 1 is attached to a wall surface is stored in advance. In addition to recording, display image data is also recorded in advance. The display image data is, for example, forward image data (first image data) and reverse image data (second image data). The RAM 24 temporarily records various types of information such as detection information of the pressure sensor 25 which is an example of a detection unit. The display image data of the image 11a displayed on the display 11 may be stored in advance in an external memory (not shown) in addition to the storage in the ROM 23 as described above.

  Next, the structure of the pressure sensor 25 will be described with reference to FIGS.

  7 and 9 show the back plate of FIG. 4 as viewed from the inside. FIGS. 7 and 8 are a front view and a cross-sectional view showing a state where the pressure sensor is not detecting pressure. FIG. It is a front view which shows the state which the sensor detected the pressure.

  As shown in FIGS. 7 and 8, the pressure sensor 25 is installed on the inner surface of the back plate 4, is fixed to the rotating shaft 26 and the rotating shaft 26, and the opening of the back plate 4 is formed from the rotating shaft 26. And a rod-like rotator 27 having a length that crosses the notch 4c of the portion 4a. A stopper (not shown) is attached to the rotating shaft 26 or the rotor 27, and the stopper 27 prevents the rotor 27 from rotating counterclockwise from the position shown in FIG. Further, a spring (not shown) is attached to the rotating shaft 26, and when the rotating element 27 is pressed to rotate a predetermined angle and the pressing force is released, the rotating element 27 is moved by the biasing force of the spring. It is configured to return to the position shown in FIG.

  On the other hand, a retaining screw 28 is attached to the wall surface W as shown in FIGS. 7 and 8, and the opening 4a is inserted into the retaining screw 28, and the reader / writer main body 1 is moved downward as shown in FIG. When the latching screw 28 is fitted into the notch 4c, the rotator 27 of the pressure sensor 25 rotates clockwise by a predetermined angle against the urging force of the spring, and the pressure sensor 25 is moved. The detection (ON) state is entered. When the pressure sensor 25 is in the detection (ON) state, the vertical direction of the image 11a displayed on the display 11 is switched so as to be reversed (changed) as shown in FIGS.

  When the reader / writer body 1 is pushed upward and removed from the notch 4c through the opening 4a with respect to the latching screw 28, the rotator 27 of the pressure sensor 25 is predetermined in the counterclockwise direction by the biasing force of the spring. And the pressure sensor 25 is in a non-detection (OFF) state. When the pressure sensor 25 is in the non-detection (OFF) state, the vertical direction of the image 11a displayed on the display 11 is switched so as to be reversed (changed) as shown in FIG. Return to.

  Next, the operation of this embodiment will be described.

  As shown in FIG. 10, when the mobile phone 30 with the IC chip is placed so as to approach the reader / writer main body 1 placed on the table within a predetermined distance (about 10 cm), the presence of the mobile phone 30 exists. Is detected via the antenna 15, and the recorded information recorded is read (or information is written).

  Then, the plurality of LEDs 13 are turned on, and the light is incident on the side surface of the display 11 while changing the optical axis by the reflectors 14a and 14b, and the display 11 is surface-emitted to read or write information. This is to inform the user. Here, for example, an image 11a of a mobile phone is displayed on the display 11, and when the LED 13 is turned on, the image 11a is displayed as if it is emitting light.

  By the way, in this embodiment, as shown in FIG. 4, the opening 4a and the notch 4c are formed in the back plate 4, and the reader / writer main body 1 is shown in FIG. 8 using the opening 4a and the notch 4c. It hooks on the latching means such as the latching screw 28 attached to. In this case, as shown in FIG. 1, when the reader / writer main body 1 with the lower side being low is attached to the wall surface W, it becomes difficult for the user to hold the mobile phone 30 against the display 11. Therefore, in the present embodiment, the user can easily put the mobile phone 30 on the display 11 by changing the upper and lower installation directions of the reader / writer body 1 so that the upper side of the reader / writer body 1 is lowered.

  Further, as shown in FIG. 8, the opening 4a is inserted into the latching screw 28 attached to the wall surface W, and the reader / writer main body 1 is pushed downward as shown in FIG. When fitted, the rotator 27 of the pressure sensor 25 rotates clockwise by a predetermined angle against the urging force of the spring, and the pressure sensor 25 enters a detection (ON) state.

  When the pressure sensor 25 is in a detection (ON) state, this detection signal is sent to the CPU 20. The CPU 20 obtains the detection signal of the pressure sensor 25 and switches the image displayed on the display 11 so that the vertical direction is reversed (changed) as shown in FIG. Accordingly, even when the vertical installation direction of the reader / writer main body 1 is changed, the image 11a displayed on the display 11 can be vertically inverted as shown in FIG. 11, and the appearance is improved.

  Thus, in this embodiment, for example, the CPU 20 is caused to perform an interrupt process by a change in the output of the pressure sensor 25. That is, if the CPU 20 displays the normal image (first image) on the display 11 until the output of the pressure sensor 25 changes, the CPU 20 writes the reverse image (second image) next, otherwise The reverse is done.

  Unlike this control, the CPU 20 constantly monitors the signal input port of the pressure sensor 25. If the pressure sensor 25 is in the ON state, the CPU 20 displays a reverse image (second image) in the display memory. If the writing is in the OFF state, the normal image (first image) may be written into the display memory, and this operation may be repeated at a predetermined time interval.

  On the other hand, when the reader / writer main body 1 is removed from the wall surface W, the reader / writer main body 1 is pushed upward and removed from the notch 4c through the opening 4a with respect to the latching screw 28. The rotator 27 of the sensor 25 rotates a predetermined angle in the counterclockwise direction, and the pressure sensor 25 enters a non-detection (OFF) state.

  When the pressure sensor 25 is not detected (OFF), the image displayed on the display 11 is switched so that the vertical direction of the image is reversed (changed) as shown in FIG. Return. As a result, even when the reader / writer main body 1 is installed on the table, the lower side remains low as shown in FIG. 1, and the user can easily hold the mobile phone 30 over the display 11, and the user can contact the reader / writer without contact. Can be recognized reliably and easily.

  As described above, according to the present embodiment, the display 11 that is disposed on the front surface of the reader / writer body 1 and displays an image, the opening 4a and the cutout portion 4c for attaching the wall surface W provided on the back surface of the reader / writer body, The pressure sensor 25 that detects that the reader / writer body 1 is attached to the wall surface W by the opening 4a and the notch 4c, and the image 11a that is displayed on the display 11 when it is detected that the reader / writer body 1 is attached to the wall surface W. By changing the image 11a displayed on the display 11 to the correct direction even when the upper and lower installation directions of the reader / writer main body 1 are reversed on the wall surface W. The user can always easily recognize the image 11a.

  Further, according to the present embodiment, by changing the vertical direction of the image 11 a displayed on the display 11, the reader / writer main body 1 is attached to the wall surface W, and the vertical installation direction of the reader / writer main body 1 is reversed. Even in this case, the user can easily recognize the image 11a by changing the image 11a displayed on the display 11 in the correct direction.

  Further, according to the present embodiment, the reader / writer main body 1 includes a casing 2 formed in a box shape and a decorative panel 9 attached to the casing 2 with the mounting screws 10a and 10b. 9 can be attached to and detached from the housing 2 with the mounting screws 10a and 10b, so that the decorative panel 9 has a colored pattern. When changing the colored pattern, the mounting screws 10a and 10b are removed to make up By replacing the panel 9 with a decorative panel of another color pattern and mounting it, the decorative panel 9 can be changed to one having a different color pattern.

  And according to this embodiment, even if the upper and lower installation directions of the reader / writer main body 1 are reversed by forming the recess 8 for drawing out the power cable 16 on the installation surface side of the housing 2, By pulling out the cable 16 through the recess 8, the routing portion of the power cable 16 is not exposed around the reader / writer main body 1, and the power cable 16 becomes an obstacle when the mobile phone 20 is placed on the surface emitting panel 11. Can be avoided.

  In the present embodiment, the pressure sensor 25 detects that the reader / writer body 1 is attached to the wall surface W. However, the present invention is not limited to this. For example, it is detected by a detection means such as a normal limit switch. You may make it do.
