Description

  The present invention relates to an electronic device that prevents a user from erroneously storing (writing) firmware.

  The firmware is a control program positioned between the hardware and the software, which is incorporated to control the hardware that is an electronic device. A technique is used in which a plurality of types of firmware are prepared, and different functions are incorporated into different hardware in the same configuration. For example, in recent years, a facsimile complex apparatus having a copy function, a scan function, a printer function, and a FAX function has been put into practical use. By changing the type of firmware incorporated in the facsimile complex apparatus, the function can be increased or decreased, Its function (commercial value) can be changed.

  Conventionally, the firmware has been updated by replacing the ROM in which the firmware is stored. Recently, however, a connection interface for a compact flash (registered trademark) card (hereinafter referred to as a CF card) is provided in the hardware. A method of updating firmware by connecting a CF card storing desired firmware has been proposed. According to this method, it is very easy to cope with a bug and to cope with version upgrade, the burden on the service provider is reduced, and the cost is useful.

However, since the firmware can be easily changed as described above, it is assumed that various humans perform the writing process. Therefore, the purchaser confirms that the price has been paid by the firmware purchaser. Is a technology that allows the download of firmware when it is determined that the purchaser is a legitimate purchaser. (For example, refer to Patent Document 1). For example, in order to prevent unauthorized writing of firmware, when writing, for example, it is requested to input a serial number, and it is determined whether the input serial number is valid. A method of permitting writing when it is determined is known. In this method, a serial number is assigned to each user. However, information regarding the regularity of the serial number is stored in a storage medium such as a CD-ROM, not the serial number itself, and is input. By judging whether or not the serial number conforms to a predetermined rule, unauthorized writing is prevented.
JP 2002-132368 A

  However, in the conventional method for determining whether or not the serial number is valid based on the regularity of the serial number as described above, if the regularity of the serial number is broken, it is determined to be valid. There was a problem that writing of firmware was permitted. In addition, since information regarding the regularity of serial numbers and logic for determining whether or not the serial number is valid must be stored in the storage medium, the information to be stored in the storage medium is complicated. There was a problem.

  The above-described technology is based on the premise that the desired firmware is downloaded, and determines whether or not the user is a valid user (purchaser). Does not assume that firmware will be downloaded by mistake. Therefore, for example, in a facsimile complex apparatus, since the function is changed by changing the firmware to be incorporated as described above, there is a possibility that the specification of the apparatus becomes unintentional if the firmware is written erroneously. there were. For example, there is a possibility that a user who does not have knowledge about the firmware writes the firmware without knowing the contents of the firmware, causing a problem in the electronic device, and in some cases even failing to start up the electronic device.

  In other words, since it is inefficient to individually manufacture a plurality of types of facsimile multifunction devices having different functions, a storage medium storing different firmware for each function is generated, and the firmware stored in the storage medium is stored in the facsimile multifunction device. By writing, it was a facsimile multifunction device having different functions. Therefore, if the firmware is accidentally written, the operation operation or the device drive operation may be different from the desired one, so that the electronic device can be prevented from being erroneously written.

Perform various software functions. The flash memory 11 is an internal memory (built-in memory) incorporated in advance in the apparatus, and stores firmware that is various control programs necessary for the operation of the facsimile composite apparatus 1. The RAM 12 stores temporary data generated when executing a software function.

  The reading unit 13 reads a document using a CCD image sensor, for example, and outputs the read image data. The optical unit irradiates and scans the original fed to the platen glass, and the reflected light from the original is taken into the CCD image sensor via a mirror, a lens, etc., and the scanned original image data is read. The read image data is output after being subjected to shading processing or the like.

  The recording unit 14 is an electrophotographic printer device, and is an image corresponding to image data of a document read by the reading unit 13, image data received by facsimile communication, image data sent from an external PC, and the like. On the paper. The display unit 15 is a display device such as a liquid crystal display device or a CRT display, displays the operating state of the facsimile multifunction device 1, displays a screen prompting the user to input an operation, or reads an image of a document read for transmission. Data, image data transmitted from other facsimile machines or PCs, etc. are displayed.

  The codec unit 17 encodes and compresses the image data and decodes the encoded and compressed image data. The image memory 18 stores image data encoded by reading a document, image data received from another facsimile multifunction peripheral or PC, and encoded.

  The modem 19 is composed of a facsimile modem capable of facsimile communication. The modem 19 is directly connected to the NCU 20. The NCU 20 is hardware that performs operations for closing and opening a line L1 with a public switched telephone network (PSTN), and connects the modem 19 to the PSTN as necessary. The facsimile complex apparatus 1 is connected to other facsimile apparatuses by PSTN so that normal facsimile communication can be performed. The PC interface unit 21 is connected to an external PC via a communication line L2 such as a LAN, and exchanges data with the PC. Various image data created and edited by an external PC are transmitted to the facsimile multifunction apparatus 1 (PC interface unit 21) via the communication line L2, and an image corresponding to the transmitted image data is transmitted to the facsimile multifunction apparatus. 1 (recording unit 14) is printed out on paper.

  The memory card interface unit 22 is a connection unit for mounting a CF card 30 that is a removable external storage medium (portable storage medium) to the apparatus. The CF card 30 has identification information for identifying the firmware 30a and the firmware 30a. 30b. When a user such as a service provider connects (inserts) the CF card 30 to the memory card interface unit 22, the control unit 10 transmits the firmware 30 a and the identification stored in the CF card 30 through the memory card interface unit 22. Information 30b is accessed as appropriate.

  The operation unit 16 is for operating the multifunction facsimile apparatus and includes various function keys. As function keys characteristic of the present invention, there are a firmware write key 16a for setting whether or not to write firmware, and an authentication information input key 16b for accepting input of authentication information from the user. When the authentication information is a character string such as a general password, the authentication information input key 16b is specifically composed of a character key, a numeric keypad, and the like. Needless to say, a short dial key, a one-touch dial key, and the like (not shown) are provided as in the conventional facsimile multifunction apparatus. In addition, by using the touch panel system for the display unit 15, some or all of the various function keys of the operation unit 16 can be substituted.

Next, the operation of the firmware writing process in the facsimile multifunction machine according to the first embodiment of the present invention will be described. FIG. 2 is a flowchart showing the operation procedure of the firmware writing process according to the first embodiment of the present invention.
The control unit 10 determines whether or not the firmware writing process is set based on whether or not the firmware writing key 16a is pressed (step S1). If the firmware writing process is not set (S1: NO), the process returns to S1.

  When the firmware writing process is set (S1: YES), the authentication information input key 16b accepts input of authentication information from the user (step S2). When the authentication information is input from the operation unit 16, the control unit 10 accesses the CF card 30 through the memory card interface unit 22, reads the identification information stored in the CF card 30, and receives the authentication received in S2. It is determined whether or not the information matches the identification information (step S3).

  Since the identification information is information for identifying the firmware stored in the CF card 30, if it is determined that the authentication information received in S2 does not match the identification information (S3: NO), the CF card 30 Therefore, the control unit 10 prohibits execution of a process (storage process) for writing the firmware to the flash memory 11 (step S4). Then, an error display indicating that the authentication information does not match the identification information, that is, the firmware storage process has not been executed is displayed on the display unit 15 to notify the user (step S5).

  On the other hand, if it is determined that the authentication information received in S3 and the identification information match (S3: YES), the firmware stored in the CF card 30 matches the firmware that the user tried to write. Therefore, the control unit 10 executes a process (storage process) for writing the firmware to the flash memory 11 (step S6).

  As described above, according to the present embodiment, when the authentication information received by the authentication information input key 16b matches the identification information for identifying the firmware, the firmware is stored and written to the flash memory 11. However, if the authentication information does not match the identification information, execution of the storage process of the firmware is prohibited, and the flash memory 11 cannot be written. This prevents undesired firmware from being written by mistake, and there is no possibility that the operation operation or the device driving operation is different from the desired one.

(Embodiment 2)
FIG. 3 is a block diagram showing a configuration of a facsimile composite apparatus which is an example of an electronic apparatus according to Embodiment 2 of the present invention. The facsimile multifunction apparatus 2 which is an example of the electronic apparatus according to the second embodiment of the present invention may have a case where the firmware 30a stored in the CF card 30 in the operation unit 16 is different from the desired firmware. The difference is that a compulsory storage processing key 16c for receiving an input as to whether or not to execute processing (storage processing) for writing to the flash memory 11 is provided. Since other configurations are the same as those in FIG. 1, the description thereof is omitted.

FIG. 4 is a flowchart showing an operation procedure of firmware writing processing according to the second embodiment of the present invention.
The controller 10 determines whether or not the firmware writing process is set based on whether or not the firmware writing key 16a is pressed (step S11). If the firmware writing process is not set (S11: NO), the process returns to S11.

  When the firmware writing process is set (S11: YES), the authentication information input key 16b accepts input of authentication information from the user (step S12). The control unit 10 accesses the CF card 30 through the memory card interface unit 22, reads the identification information stored in the CF card 30, and determines whether or not the authentication information received in S12 matches the identification information. Determination is made (step S13).

  Since the identification information is information for identifying the firmware stored in the CF card 30, if it is determined that the authentication information received in S12 does not match the identification information (S13: NO), the CF card 30 Since the firmware stored in is different from the firmware that the user tried to write, an error display indicating that the authentication information and the identification information do not match is displayed on the display unit 15 to notify the user ( Step S14).

  Then, even if the firmware is different from what the user tried to write, the forced storage processing key 16c receives an input as to whether or not to execute the processing (storage processing) forcibly writing to the flash memory 11 (step S15). In S15, when an input to execute the storage process is received (S15: YES), since the user is considered to be a person with knowledge of the firmware, the control unit 10 writes the firmware in the flash memory 11. (Storage processing) is executed (step S16). On the other hand, when an input indicating that the storage process is not executed is received in S15 (S15: NO), the control unit 10 stores the firmware in the flash memory 11 because the user is considered to be a person who has no knowledge of the firmware. Execution of the writing process (storage process) is prohibited (step S17).

  On the other hand, if it is determined that the authentication information and the identification information received in S13 match (S13: YES), the firmware stored in the CF card 30 matches the firmware that the user tried to write. Therefore, the control unit 10 proceeds to S16 and executes a process of writing the firmware into the flash memory 11 (storage process).

  As described above, according to the present embodiment, when the authentication information received by the authentication information input key 16b matches the identification information for identifying the firmware, the firmware is stored and written to the flash memory 11. However, if the authentication information does not match the identification information, an input as to whether or not to execute a process (storage process) to be written in the flash memory 11 is accepted, and the firmware storage process is executed based on the input. to decide. When an input indicating that the storage process is not executed is received, the firmware is not written to the flash memory 11.

  In the present embodiment, after notifying the user that the authentication information and the identification information do not match (S14), the firmware is written into the flash memory 11 when an input to execute the storage process is received. (S16) As described above, the firmware is written into the flash memory 11 when an input for executing the storage process is received while notifying the user that the authentication information and the identification information do not match. Also good. The same applies to the case where execution of the process of writing firmware is prohibited.

(Embodiment 3)
In the second embodiment, when the authentication information does not match the identification information, an error display indicating that the authentication information does not match the identification information is displayed on the display unit 15 to notify the user. The operation content of the device based on the above may be notified, and the third embodiment is such a configuration. Note that the third embodiment is different from the second embodiment in that information relating to the operation content of the device based on the firmware is attached (stored) to the firmware 30a to be written, and other configurations are the same as those in FIG. Therefore, the explanation is omitted, and the operation procedure is explained to clarify the difference.

FIG. 5 is a flowchart showing the operation procedure of the firmware writing process according to the third embodiment of the present invention.
The control unit 10 determines whether or not the firmware writing process is set based on whether or not the firmware writing key 16a is pressed (step S21). If the firmware writing process is not set (S21: NO), the process returns to S21.

  When the firmware writing process is set (S21: YES), the authentication information input key 16b accepts input of authentication information from the user (step S22). The control unit 10 accesses the CF card 30 through the memory card interface unit 22, reads out the identification information stored in the CF card 30, and determines whether the authentication information received in S22 matches the identification information. Determination is made (step S23).

  Since the identification information is information for identifying the firmware stored in the CF card 30, if it is determined that the authentication information received in S22 does not match the identification information (S23: NO), the CF card 30 Therefore, the control unit 10 reads the information related to the operation content stored in the firmware 30a (step S24), and is based on the firmware. The operation content of the device is displayed on the display unit 15 to notify the user (step S25).

  A process for forcibly writing the firmware to the flash memory 11 after allowing the user to recognize the operation contents of the device, that is, the operation contents of the facsimile multifunction peripheral 1 when the firmware is written to the flash memory 11 and executed. An input as to whether or not to execute (storage processing) is accepted by the forced storage processing key 16c (step S26). In S26, when an input to execute the storage process is accepted (S26: YES), the user has instructed to execute the process of writing the firmware after recognizing the operation content of the device. 10 executes a process (storage process) for writing the firmware to the flash memory 11 (step S27). On the other hand, if an input indicating that the storage process is not to be executed is received in S26 (S26: NO), the user has instructed not to execute the process of writing the firmware after recognizing the operation content of the device. The control unit 10 prohibits execution of a process (storage process) for writing firmware to the flash memory 11 (step S28).

  On the other hand, if it is determined that the authentication information received in S23 matches the identification information (S23: YES), the firmware stored in the CF card 30 matches the firmware that the user is trying to write. Therefore, the control unit 10 proceeds to S27 and executes a process of writing the firmware into the flash memory 11 (storage process).

  As described above, according to the present embodiment, when the authentication information received by the authentication information input key 16b matches the identification information for identifying the firmware, the firmware is stored and written to the flash memory 11. However, if the authentication information does not match the identification information, the operation content of the device based on the firmware is notified and recognized by the user, and then the process of writing to the flash memory 11 (storage process) is executed. Whether or not to execute the storage process of the firmware is determined based on the input. When an input indicating that the storage process is not executed is received, the firmware is not written to the flash memory 11.

  In the present embodiment, after notifying the user of the operation content of the device based on the firmware (S25), the firmware is written in the flash memory 11 when an input to execute the storage process is received (S27). However, the firmware may be written into the flash memory 11 when an input to execute the storage process is received while notifying the user of the operation content of the device based on the firmware. The same applies to the case where execution of the process of writing firmware is prohibited.

  In the second embodiment, an error display indicating that the authentication information and the identification information do not match is displayed on the display unit 15 to notify the user. In the third embodiment, the operation content of the device based on the firmware is displayed. The information is displayed on the display unit 15 to notify the user, but the notification method is not limited to this, and for example, a voice may be output from a speaker (not shown) to notify the user. Good.

  In each embodiment, the firmware write key 16a is pressed to execute the process related to the writing of the firmware. However, when the CF card 30 is attached to the memory card interface unit 22, the user can update the firmware. Therefore, when the controller 10 detects that the CF card 30 is inserted, the controller 10 may execute the process without pressing the firmware write key 16a. .

  Furthermore, in each embodiment, when the authentication information and the identification information do not match, an input error by the user is considered, so that re-input of the authentication information may be accepted. The external storage medium that can be attached to and detached from the apparatus is not limited to the CF card, but may be a small memory card such as an SD memory card, a memory stick, or smart media, or a small hard disk apparatus such as a microdrive. Good. Furthermore, although the facsimile complex apparatus has been described as an electronic apparatus, it goes without saying that the present invention can be applied to an electronic apparatus controlled by firmware.
