FIG. 21 is an image diagram showing a window for displaying a stamp owned by mobile phone 100 according to the present embodiment. More specifically, FIG. 21A is an image diagram showing the initial screen of the window. FIG. 21B is an image diagram showing a state in which the mobile phone 100 displays a stamp owned by itself and a stamp not owned by itself.

  Referring to FIGS. 20 and 21A, control unit 106 causes display 107 to display an initial screen for displaying a stamp owned by itself (step S802). In step S802, the mobile phone 100 does not display stamps in the stamp field owned by itself and in the stamp field not owned by itself.

  The control unit 106 initializes the value of the variable i in the volatile memory 103 (step S804). The control unit 106 determines whether or not the value of ccnt matches the variable i (step S806). If the value of ccnt does not match variable i (NO in step S806), control unit 106 sets the values of various variables in volatile memory 103 (step S808). More specifically, the control unit 106 sets STMPTBL [i]. Substitute the value of contID. Similarly, the control unit 106 sets values of ownerF, transF, spF, URL [], COPYRIGHT [], and PATH [].

  If 1 is stored in ownerF (YES in step S810), the control unit 106 sets a stamp in the owned stamp column of the display 107 based on the display data stored in the address of the file PATH. An icon is displayed (step S812). The control unit 106 increments the value of the variable i (step S816). The control unit 106 repeats the processing from step S806.

  The control unit 106 determines whether 1 is stored in the ownerF (step S810). If 1 is not stored in ownerF (NO in step S810), the control unit 106 sets the stamp in the unowned stamp column of the display 107 based on the display data stored in the address of the file PATH. An icon is displayed (step S814). The control unit 106 increments the value of the variable i (step S816). The control unit 106 repeats the processing from step S806.

When the control unit 106 receives an input of a new URL (YES in step S832), the control unit 106 substitutes the value of the input URL into the URL [] of the volatile memory 103 (step S834). Control unit 106 repeats the processing from step S824.

  If control unit 106 does not accept input of a new URL via tablet 119 (NO in step S824), control unit 106 determines whether or not the user has operated access button 107D (step S836). If control unit 106 determines that the user has not operated access button 107D (NO in step S836), control unit 106 determines whether an end operation from the user has been accepted (step S838).

  If control unit 106 determines that an end operation has not been received from the user (NO in step S838), control unit 106 repeats the processing from step S824. When control unit 106 receives an end operation from the user (YES in step S838), control unit 106 repeats the processing from step S842 described later.

  When it is determined that the user has operated access button 107D (YES in step S836), control unit 106 determines whether or not NULL is stored in URL [] of volatile memory 103 (step S836). S840). When NULL is stored in URL [] (YES in step S840), control unit 106 repeats the processing from step S824.

  If NULL is not stored in URL [] (NO in step S840), control unit 106 executes new stamp purchase (normal) processing (step S950). The new stamp purchase (normal) process (step S950) will be described later. Thereafter, the control unit 106 causes the display 107 to delete the window for displaying the stamps owned (step S842).
