JP6563045B2 - Image forming apparatus, program update method, and program - Google Patents

Description

  The present invention relates to an image forming apparatus, a program update method, and a program.

An image forming apparatus such as a multifunction peripheral has a CPU of a main body controller unit that controls the entire image forming apparatus, and a CPU of an option unit that individually controls optional functions such as FAX and folding functions. When the CPU of the option unit operates based on a control program corresponding to each function stored in a storage device such as a ROM, each function such as a FAX and a folding function is realized.
Conventionally, in order to use an optional function, it is necessary for a service person to install an optional unit and update the control program of the combined optional unit that matches the version of the control program of the main body. As a method for updating the control program for the option unit, a technique as disclosed in Patent Document 1 has been proposed. In the technique, the main body controller compares the control program version in the option unit with that on the server. Then, if the version of the option unit is older, the main body controller downloads the option unit control program on the server to the main body, and then downloads it to the option unit.

JP 2008-116660 A

An option unit such as a fax board may be used as a common option unit across a plurality of models, and is operated as the same unit number (unit + control program) from the viewpoint of easy inventory management.
However, every time a new model is produced, the control program of the option unit is often modified to cope with some problem, and naturally the program version also goes up each time. In this case, it is necessary to download an option unit program for a model already on the market after the evaluation is completed for a version of a plurality of models.
When using a new optional function, the service person first attaches the optional unit to the main body. However, since the same part number is managed as it is, the version of the control program in the option unit is often old. In the case of the technique disclosed in Patent Document 1, in such a case, the option unit control program must be updated after accessing the server and downloading the option unit program to the main body. Also, it is necessary to determine whether the control program of the option unit corresponds to the version of the control program of the main body on the main body side.

  The present invention has been made in view of such a problem, and an object thereof is to easily prevent the occurrence of a problem due to a mismatch between program versions of a main body and an option unit.

Therefore, the image forming apparatus of the present invention is an image forming apparatus capable of executing printing, a connection interface for connecting an option unit to the image forming apparatus main body , a setting unit for setting the type of the option unit, first update program for updating the control program options units type set by the setting means, and a program for updating the main body control program for controlling the image forming apparatus main body, the second update flop Rogura beam to accommodate the first updating program, before the option unit is connected to said connection interface, receiving means for receiving via the network, by the receiving means It received the first update program and the second program for updating, storing stores hand If, reads the second update program stored by the storage means, and controlling said image forming apparatus by using the second update program read, and the first update stored by the storage means Control means for operating the option unit connected to the connection interface using the first update program read out.

  According to the present invention, it is possible to easily prevent the occurrence of a problem due to a mismatch between program versions of the main body and the option unit.

Then, the CPU 101 determines whether the version of the control program of the fax unit 200 has been acquired based on the response to the command. If the version of the control program of the fax unit 200 can be acquired, the CPU 101 advances the process to step S105. If the version of the control program of the fax unit 200 cannot be acquired, the CPU 101 advances the process to step S108.
In step S105, the CPU 101 compares the acquired version with the version of the control program of the fax unit stored in the download area of the ROM 102 of the main body controller unit.
In step S106, the CPU 101 determines whether or not the acquired version is older as a result of the comparison. As a result of comparison, if the acquired version is older, the CPU 101 advances the process to step S107. If the acquired version is not older, the process advances to step S108.

In step S <b> 107, the CPU 101 copies the fax unit control program stored in the download area to the program update area of the ROM 102. More specifically, the CPU 101 copies the latest fax unit control program included in the main body control program stored in the download area to the program update area of the ROM 102.
In step S <b> 108, the CPU 101 determines whether or not the folder unit 300 to be controlled by the main body controller unit 100 is connected. If the folder unit 300 is connected, the CPU 101 advances the process to step S109. If the folder unit 300 is not connected, the CPU 101 advances the process to step S114.
In step S <b> 109, the CPU 101 transmits a command related to an acquisition request for the version of the control program stored in the flash memory 202 in the folder unit 300 to the folder unit 300 to be connected. Then, the CPU 101 determines whether or not the version of the control program for the folder unit 300 has been acquired based on the response to the command. If the version of the control program for the folder unit 300 can be acquired, the CPU 101 proceeds to step S110. If the version of the control program for the folder unit 300 cannot be acquired, the process proceeds to step S114.
In step S110, the CPU 101 compares the acquired version with the version of the folding unit control program stored in the download area of the ROM 102 of the main body controller unit.

In step S111, the CPU 101 determines whether the acquired version is older as a result of the comparison. As a result of comparison, if the acquired version is older, the CPU 101 advances the process to step S1112. If the acquired version is not older, the process advances to step S114.
In step S <b> 112, the CPU 101 copies the folder unit control program stored in the download area to the program update area of the ROM 102.

In step S117, the CPU 101 deletes the option unit control program in the program update area.

<Embodiment 2>
In the first embodiment, the CPU 101 has been described so as to acquire and hold a main body control program including all the latest control programs of option units that can be connected to the main body controller unit 100 from the server.
However, holding the main body control program including the latest control programs of all the optional units that can be connected is a waste of memory.
Therefore, when the CPU 101 of this embodiment detects a predetermined operation, the CPU 101 displays an option unit selection screen shown in FIG. FIG. 5 is a diagram illustrating an example of the option unit selection screen. On the option unit selection screen as shown in FIG. 5, the user selects an option unit that does not hold the latest program, and selects an OK button. Thus, the user can select an option unit that does not hold the latest program. On the option unit selection screen, the CPU 101 sets the selected option unit as an option unit that does not hold the latest program, and stores setting information or the like in the ROM 102 or the like.
Based on the setting information, the CPU 101 may acquire a main body control program including only the latest option unit control program required by the user from the server. That is, the CPU 101 may acquire from the server a main body control program including option units other than the option units set as option units that do not hold the latest program based on the setting information. In addition, the CPU 101 may once obtain a main body control program similar to that of the first embodiment from the server, delete unnecessary control programs for optional units from the main body control program, and save them based on the setting information.

In step S <b> 200, the CPU 101 determines whether connection of an option unit to the main body controller unit 100 is detected. If the connection of the option unit is detected, the CPU 101 advances the process to step S201. If the connection of the option unit is not detected, the CPU 101 repeats the process of step S200.
In step S201, the CPU 101 determines, based on the setting information, whether the option unit for which connection has been detected is an option unit that is set not to hold the latest program. If the option unit whose connection is detected is an option unit that is set not to hold the latest program, the CPU 101 advances the process to step S205. On the other hand, if the option unit whose connection has been detected is an option unit that has not been set unless it holds the latest program, the process proceeds to step S202.

In step S202, the CPU 101 compares the version of the option unit control program acquired from the option unit detected to be connected with the version of the option unit control program stored in the ROM 102 download area of the main body controller unit. To do.
In step S203, the CPU 101 determines whether the version acquired from the option unit is older as a result of the comparison. As a result of comparison, if the version acquired from the option unit is older, the CPU 101 advances the process to step S204. If the acquired version is not older, the process returns to step S200.
In step S <b> 204, the CPU 101 copies the option unit control program stored in the download area to the program update area of the ROM 102.

On the other hand, in step S205, the CPU 101 determines whether or not the server has the latest control program for the option unit whose connection has been detected. For example, the CPU 101 acquires the version of the control program of the option unit from the option unit whose connection is detected. Then, the CPU 101 transmits a command for inquiring whether a newer version of the option unit than the version exists in the server. Then, the CPU 101 may determine whether or not the server has a version newer than the version of the option unit based on a response from the server to the command.
If the server has the latest control program for the option unit for which connection is detected, the CPU 101 proceeds to step S206. If the server does not have the latest control program for the option unit for which connection has been detected, the process proceeds to step S200. Return to.

In step S206, the CPU 101 acquires the latest control program of the option unit for which the connection is detected from the server (acquires the latest program). Note that the CPU 101 may acquire only the latest control program of the option unit in which the connection is detected from the server, or may acquire a main body control program including the latest control program of the option unit. May be.
In step S207, the CPU 101 copies the acquired latest control program of the option unit to the program update area (latest program copy).
In step S <b> 208, the CPU 101 changes the setting information and the like so as to delete the option unit detected to be connected from the option unit that does not hold the latest program. Alternatively, the CPU 101 sets the option unit in which the connection is detected as the option unit that holds the latest program in the setting information or the like.
In step S209, the CPU 101 restarts the main body of the multifunction machine 10.
