Abstract

PURPOSE:To improve the operability of the unit in the case of initial setting by storing an initial data at application of power and discriminating whether or not the stored initial data is a correct data suitable for the unit. CONSTITUTION:A CPU 15 discriminates, at application of power, whether or not configuration information specific to the unit set by the combination of switch groups 14 is the same as configuration information of control information stored in a RAM 11. When they differ from each other, a controller having configuration information corresponding to the configuration information specific to the unit is read from ROMs 12, 13 and the result is written and stored in the RAM 11 as the initial value to terminate the initializing processing.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a data processing device that sets data necessary for performing a predetermined processing operation as an initial value (initial value). The present invention also relates to a data processing device for setting initial values.

[Conventional technology]

Conventionally, this type of device has been used for image recording in copying machines, etc. When the power is turned on, the above device issues an initialization command to perform initial settings, such as the number of trays to be used, paper size, and instructions for double-sided/single-sided copying. When a user (including an initialization command from the host computer) issues instructions such as whether to use a stacker or manual feed, the central processing unit (CPU) executes a program according to the initial value data to record the desired image. was going on.

[Problem to be solved by the invention]

However, as mentioned above, in the data processing device described above, the user must specify an initialization command to perform initial settings when the device is powered on, which makes the operation complicated and causes problems such as poor operability of the device. there were.

The present invention has been made in view of the above problems, and it is possible to perform initial settings by determining whether the initial value data is correct data suitable for the device without the user specifying an initialization command when the power is turned on. The objective is to provide a data processing device that can perform the following tasks.

[Means to solve the problem]

In the present invention, data used when performing a predetermined processing operation such as image recording, and control information consisting of version information (number information) and configuration information (number information) of the data are written by a CPU or the like. A first memory such as a RAM that stores initial value data according to control.
a second storage means such as a ROM for storing at least two types of control information; a setting means such as a group of switches for presetting device-specific configuration information at the time of device manufacture; At times, a determining means such as a CPU that determines whether the set configuration information and the configuration information stored in the first storage means are the same, and depending on the determination, a and storage control means such as a CPU that causes control information in the second storage means corresponding to configuration information to be stored in the first storage means.

[Effect]

If the determining means determines that the device-specific configuration information and the configuration information stored in the first time tξ means are not the same, the storage control means stores information in the second storage means corresponding to the configuration information. The control information within is stored in the first storage means as initial value data.

Therefore, even if the user does not issue an initialization command when the power is turned on, the initial value data is stored in the first storage means, and the CPU can read and initialize the initial value data.

〔Example〕

Embodiments of the present invention will be described in detail based on the drawings of FIGS. 1 and 2.

FIG. 1 is a block diagram showing a schematic configuration of a data processing device according to the present invention. In the figure, RAM 1l is a nonvolatile memory that stores data used when performing predetermined processing operations such as image recording, such as the number of trays to be used, paper size, double-sided/single-sided copy instructions, and
Control information consisting of data such as the presence or absence of push-button and manual feed, version information of the data, and configuration information is stored as initial value data.The configuration information is the device's This is a number indicating the type, and the version information is a number indicating the version of the device when the system was upgraded, for example.

The ROM 1'2.13 stores a plurality of types of control information to be stored in the RAM II. In addition, the above ROM
12.13, in order to have versatility with other devices,
It is assumed that control information that cannot be used in the data processing device of the present invention is also stored.

The switch group 14 indicates device-specific configuration information by the combinations thereof, and the above combinations are set, for example, at the time of manufacturing the device.

The CPU 15 controls the operation of the above-mentioned equipment and turns on the power (
When the power is turned on), the control information corresponding to the configuration information set uniquely to the device by the combination of the switch group 14 is read from the control information stored in the ROM 12.13, and is stored in the RAM 11 as initial value data. The control information is written to and stored, and desired data processing is performed in accordance with the stored control information. In addition,
In response to the initialization command from the user, the CPU 15 reads control information corresponding to configuration information set uniquely to the device from among the control information stored in the ROMI 2.13, and uses the read control information. It is also possible to write and store it in RAMI as initial value data.

Next, the initialization operation according to the present invention by the CPU 15 will be explained based on the flowchart shown in FIG.

In FIG. 2, when the CPU 15 first turns on the power (step 101), the CPU 15 uses the same configuration information as the device-specific configuration information set by the combination of the switch group 14 and the control information stored in the RAM 11. It is determined whether it is true (step 102).

Here, if the two pieces of configuration information are different, the control information having the configuration information corresponding to the device-specific configuration information is read from the ROM 12.13, and the read control information is set to the initial value. The data is written to RAM II and stored (step 104), and the initialization operation is completed.

Furthermore, if both of the above configuration information are the same, the ROM 12.13 of the configuration information corresponding to the device-specific configuration information
It is determined whether the version information in the RAM 11 is the same as the version information in the RAM 11 (step 103).

Here, if both version information is the same, RAM
It is determined that the control information in II is suitable for this device, and the initialization operation is completed.

Further, if the above two version information are different, the control information having the configuration information corresponding to the device-specific configuration information is read from the above ROMI 2.13 in step 104,
RAMI with the control information read above as the initial value.
I is written and stored, and the initialization operation is completed.

Therefore, in the present invention, the initial value data is stored in the RAM and set even if the user does not issue an initialization command (including an initialization command from the host computer). Thereafter, the CPU can perform predetermined processing operations such as image recording based on the initial values set in the RAM.

Note that the switch group that indicates configuration information is
It is possible to have it not only in the main body of the apparatus but also in an option (for example, a multi-sheet manual feed unit, etc.), and in this case, changes in the above-mentioned configuration information can be automatically detected. Therefore, initial settings that match the configuration can be automatically performed.

[Effects of the Invention] As explained above, in the present invention, the initial value data is stored when the power is turned on without issuing an initialization command, and the stored initial value data is correct data suitable for the device. Since it is possible to determine whether or not the initial value is set, the initial value can be easily set, thereby improving the operability of the device at the time of initial setting.
