Description

  The present invention relates to a portable electronic device such as a mobile phone, a PDA, and a music playback device provided with a magnetic recording device such as an HDD (Hard Disk Drive Device) and a non-contact type IC module.

  Recently, some mobile phones have been proposed, which are equipped with a non-contact IC module having a wireless communication function, or with a removable IC card equipped with a non-contact IC module. It's getting on. The non-contact type IC module is used for, for example, a railroad ticket / commuter pass function, an electronic money function, a prepaid function, and an identification card function. For example, when a user holds a mobile phone equipped with a non-contact type IC module over a data transmission / reception device for writing / reading data of an automatic ticket gate at a station, data transmission / reception by wireless communication is performed, and a ticket gate is automatically performed. be able to. Alternatively, when a product is purchased, the price of the product can be paid by wirelessly communicating with a mobile phone equipped with a non-contact IC module and a data transmitting / receiving device installed in the store. Note that the non-contact type IC module generally includes an IC (semiconductor integrated circuit) chip and an antenna coil, and the antenna coil performs wireless communication with a data transmitting / receiving device. The non-contact type IC module has a passive type that receives the magnetic force from the data transmitter / receiver and supplies the power generated by the electromagnetic induction as the power source of the IC chip, and a power source for driving the IC chip. There is an active type in which the IC chip is directly driven by the above.

On the other hand, data handled by mobile phones includes voice data, image data, character data, etc., but in order to meet the demand for higher sound quality and higher image quality in recent years, an increasingly larger memory is required. . However, since the semiconductor memory used in the past is expensive and does not have a large capacity, it is considered to use an HDD that performs magnetic recording / reproduction capable of recording at a relatively low cost and a large capacity. Recently, a small HDD has been developed and can be incorporated in a mobile phone (for example, see Patent Document 1). Therefore, in the near future, there is a high possibility that a mobile phone incorporating a contactless IC module and an HDD will be realized.

Mode 2 is a mode in which wireless communication by the non-contact type IC module 8 is prohibited and writing or reading by the HDD unit 6 is permitted.

According to mode 1, writing and reading operations of the HDD unit 6 are prohibited, and the magnetic head 28 is in the retracted position. Therefore, even if the mobile phone 10 contacts the data transmitting / receiving device 30 and receives an impact, a head crash does not occur. Further, it is not affected by the magnetic force 32 from the data transmitting / receiving device 30.
According to mode 2, since the communication of the non-contact type IC module 8 is prohibited, the HDD unit 6 can perform a writing or reading operation without being affected by the head crash or the magnetic force 32 due to the impact.

Next, the operation when the user operates the key operation unit 7 to instruct and set the mode switching (transition) to the control unit 21 will be described with reference to the flowcharts of FIGS.
In FIG. 6, when switching to mode 2 is set for the control unit 21 by the key operation unit 7 during mode 1 (step S <b> 1, the following step is omitted), wireless communication of the non-contact IC module 8 is prohibited. (S2). In addition, the user is notified of the change to mode 2 by the notification unit 25 and the display unit 4 (S3).

  In FIG. 7, when switching to mode 1 is set during mode 2 (step S11), it is determined whether the HDD unit 6 is currently writing or reading (S12). Here, if writing or reading is in progress, the notification unit 25 notifies that the mode 1 cannot be changed (S13). If the writing and reading operations are not being performed, it is determined whether or not the magnetic head 28 has been retracted (S14). If the magnetic head 28 has been retracted, the writing and reading operations of the HDD unit 6 are prohibited (S15). If the magnetic head 28 is not retracted, S15 is executed after the magnetic head 28 is retracted (S16). Thereafter, the user is notified by the notification unit 25 and the display unit 4 that the retraction operation of the magnetic head 28 has been completed and that the mode 1 has been set (S17).

  In FIG. 8, switching to mode 1 is performed (S21), and if there is a subsequent write or read request of HDD unit 6 (S22, YES), it is in mode 1 and writing and reading are impossible. Is notified by the notification unit 25 and the display unit 4 (S23). If there is no write or read request (S22, NO), mode 1 is continued as it is. Note that S21 to S23 described above are executed until switching from mode 1 to mode 2 is set, as described with reference to FIG.

According to the present embodiment, when switching from mode 1 to mode 2, wireless communication of the non-contact type IC module 8 is prohibited, so that the HDD unit 6 can write or read without being affected by impact, electromagnetic waves, or magnetic force. It can be carried out.
Further, when the mode 2 is switched to the mode 1, the writing and reading operations of the HDD unit 6 are prohibited while the magnetic head 28 is moved to the retracted position, and the retracting operation of the magnetic head 28 is completed. Since the notification unit 25 notifies that the switching has occurred, even when the mobile phone 10 is strongly applied to the reader / writer unit 28, a head crash due to an impact can be reliably prevented.

Further, the notification unit 25 and the display unit 4 notify the user of mode switching, and even if the user instructs writing or reading during mode 1, it is notified that the operation is impossible. You can call attention.
