2. Description of the Related Art In recent years, in a digital lab system for recording an image recorded on a photographic film on photographic paper, a photographic film to be recorded is set on a film carrier by an operator, and then the photographic film is predetermined by the film carrier. After being conveyed to the exposure position and irradiating the image frame of the photographic film with the reading lamp to read the film image as image data, various image processing is performed on the image data as necessary, and the result obtained is obtained. The image is recorded on the photographic paper based on the image data.

Conventionally, in such a digital laboratory system, when an error has occurred in each part constituting the system, the operation of the entire system has been stopped. That is, in the digital lab system as described above, when an error such as the photographic film cannot be transported to the exposure position, the reading lamp is cut off, or the photographic paper is jammed on the transport path, the error occurs on the photographic paper. Since it is not possible to record an image in the system, it is necessary to stop the operation of the entire system, and it is assumed that the operation of the entire system is also stopped when an error other than these occurs.

According to the control device of the first aspect, when an error occurs in the control target device, the control means continues and stops the operation of the control target device based on error state information corresponding to the generated error. Is performed. The error status information indicates the continuation and stoppage of the operation of the controlled device in accordance with the error status for each error that occurs in the controlled device, and is stored in advance in the storage unit.

Here, the error state information can be rewritten as needed by the instruction input means. Therefore, the operator can rewrite the error state information for each error that occurs in the control target device as needed.

Thus, according to the control device of the first aspect, when an error occurs in the control target device, one of the continuation and the stop of the operation of the control target device is performed based on the error state information. The error status information can be rewritten as needed, so that the operation of the controlled device can be prevented from being stopped depending on the type of error that has occurred, and the operation of the controlled device can be stopped for all errors. The operation rate of the control target device can be improved as compared with the case where the control is performed.

The control method according to claim 2 stores error information including error status information indicating continuation and suspension of the operation of the controlled device in accordance with an error state for each error generated in the controlled device. In addition, the error state information in the stored error information is rewritten as necessary, and when an error occurs in the control target device, the control is performed based on the error state information corresponding to the generated error. Either continue or stop the operation of the target device.

According to the control method of the present invention, when an error occurs in the control target device, the operation of the control target device is either continued or stopped based on error status information corresponding to the generated error. One is done. In addition,
The error status information indicates the continuation and stoppage of the operation of the control target device according to the error status for each error occurring in the control target device, and is stored in advance.

Here, the error state information can be rewritten as needed. Therefore, the operator can rewrite the error state information for each error that occurs in the control target device as needed.

Thus, according to the control method of the present invention, when an error occurs in the control target device, one of the continuation and the stop of the operation of the control target device is performed based on the error state information. The error status information can be rewritten as needed, so that the operation of the controlled device can be prevented from being stopped depending on the type of error that has occurred, and the operation of the controlled device can be stopped for all errors. The operation rate of the control target device can be improved as compared with the case where the control is performed.
