In another embodiment, the transmission mechanism 141 is coupled to the shaft of the image information medium 13. When the control switch 143 is pressed, the motor 142 moves the transmission mechanism 141 to rotate the image information medium. The position of the opening 132 of the image information medium can be easily changed. The projection module 12, the optical reader 21, and the control module 22 execute a projection and sound reproduction function according to the information area 131 of the next opening 132.

Or it is transmitted to update audio data, conduct an online lesson, conduct a video conference, or request that the main body 1 automatically project projection media.

The optical image recognition module 2 recognizes the label 133 according to the following procedure.
(101) Start.
(102) The optical reader 21 of the optical image recognition module 2 detects the label 133 of the image information medium 13 by the control module 22.
(103) It is determined whether the label 133 is valid. If “YES”, the process proceeds to step (104), and if “NO”, the process returns to step (102).
(104) It is determined whether or not to perform transmission. If “YES”, the process proceeds to step (105), and if “NO”, the process proceeds to step (106).
(105) Wireless transmission is performed.
(106) It is determined whether or not to execute the reproduction process. If “YES”, the process proceeds to step (107), and if “NO”, the process proceeds to step (102).
(107) Audio is reproduced.

  As shown in the above steps, the optical image recognition module 2 uses the optical image sensor 211 of the optical reader 21 that detects the label 133, and the processing device 221 searches for matching data in the data storage element 222. If label 133 is determined to be a valid label, a control signal is generated accordingly. If it is determined that the label 133 is an invalid label, the label 133 is continuously detected until it is determined that the label 133 is a valid label. Next, the processing device 221 determines whether or not the button unit 224 has been pressed, and a control signal is transmitted via the wireless transmission module 226.

The mechanism 141 is driven. Alternatively, a control signal is transmitted to the wireless transmission module outside the electronic device via the wireless transmission module 226 in order to reproduce sound or perform other functions. In addition, when the processing device 221 determines not to perform wireless transmission, the processing device 221 determines whether to reproduce sound. If the processing device 221 determines to play back audio, the control signal is transmitted to the multimedia playback unit 223 for playback of the corresponding audio. If the processing device 221 decides not to reproduce sound, the optical image sensor 211 continues to detect the label 133.
