FIG. 8 is a functional block diagram showing a main configuration of the digital multifunction peripheral 100 according to the fourth embodiment of the present invention. The digital multi-function peripheral 100 according to the fourth embodiment is configured such that a computer program for performing the operation can be provided on a portable recording medium A such as a CD-ROM via the I / F 15. . Furthermore, the digital multifunction peripheral 100 according to the fourth embodiment is configured such that the computer program can be downloaded from an external device (not shown) via the communication unit 14. The contents will be described below.

  The digital multi-function peripheral 100 of Embodiment 4 includes an exterior (or interior) recording medium reading device (not shown), and allows the recording medium reading device to determine whether an external storage medium is connected. It is possible to record a program that detects the attributes of a file stored in an external storage medium, determines whether the instruction is an administrator instruction or a user instruction, and displays an operation screen based on the determination result. For example, the CPU 21 installs the portable recording medium A and installs the program in the ROM 22. Such a program is loaded into the RAM 24 and executed. Thus, the digital multifunction peripheral 100 according to the first embodiment of the present invention functions.

  The recording medium may be a so-called program medium, a tape system such as a magnetic tape and a cassette tape, a magnetic disk such as a flexible disk and a hard disk, and a disk system of an optical disk such as a CD-ROM / MO / MD / DVD, It may be a medium carrying a fixed program code including a card system such as an IC card (including a memory card) / optical card or a semiconductor memory such as a mask ROM, EPROM, EEPROM, flash ROM or the like.

  It may be a medium that fluidly carries the program code so as to download the program code from the network via the communication unit 14. When the program is downloaded from the communication network in this way, the download program may be stored in the main device in advance or may be installed from another recording medium. The present invention can also be realized in the form of a computer data signal embedded in a carrier wave in which the program code is embodied by electronic transmission.

  The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
