Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention has an image communication device, and particularly has a manual call reception mode and an automatic call reception mode. The present invention relates to an image communication device that automatically receives image data based on detection of an incoming call in a call mode.

[Prior Art] Conventionally, facsimile machines are known that have an automatic call reception mode switching function that sets automatic reception and manual call reception modes in accordance with a user's time designation.

A conventional facsimile machine having an automatic incoming mode switching function registers the automatic incoming mode setting time, and when the time comes, sets the automatic incoming mode, and also registers the manual incoming mode setting time, and when the time comes, Setting to Manual Receiving Mode 9 For example, it is possible to set the facsimile machine to manual receiving mode at 9:00 a.m. when the office starts, and setting the facsimile machine to automatic receiving mode at 6:00 p.m. when the office ends. .

[Problems to be Solved by the Invention] However, the above conventional example has a drawback that even on company holidays, the manual call reception mode is activated from 9200 am to 6:00 pm, and facsimile reception is not possible during this period.

Also, in a company with a small number of people, it is conceivable that Mamoru will not be in the room even on the day of work. At this time, there is a drawback that facsimile reception becomes impossible.

An object of the present invention is to solve the above problems.

[Means for Solving the Problems] In order to solve the above problems, the present invention has a manual call reception mode and an automatic call reception mode. In an image communication device that automatically receives image data based on incoming call detection in the incoming call mode, two time periods are set for incoming calls in either the manual incoming call mode or the automatic incoming call mode, and the set time is set. The present invention includes a receiving mode control means for receiving a call in each receiving mode in each zone, and a receiving mode switching means for switching to an automatic receiving mode if the operator does not respond for a predetermined time after detecting an incoming call during a manual receiving mode time period. Adopted.

[Function] According to the above configuration, even if manual call reception is set by the call reception mode control means, it is possible to automatically switch to automatic reception mode if there is no response from the operator for a predetermined period of time or more.

In step 5122, it is determined whether the timer has timed out. If the timer times out, the process proceeds to step Sl10, where an automatic call reception is performed, and if the timer does not time out, the process proceeds to step 5120.

According to the above configuration, when the manual reception mode setting time comes,
The facsimile device is set to manual incoming call mode, and when the automatic incoming mode setting time comes, the facsimile device is set to automatic incoming mode, and after a predetermined period of time has elapsed after incoming call detection in manual incoming mode, the facsimile device shifts to automatic incoming mode.

As a result, on the day of dispatch, it is set to manual incoming call mode. For example, in the previous example, from am9:00 to pm6
:00, even if the device is unattended, facsimile reception is possible if the sender waits for a predetermined period of time.

Further, it is possible to change the automatic call reception mode setting time registration and the manual call reception mode setting time registration depending on the day of the week or the year, month, and day.

Therefore, it is now possible to set the daytime automatic call reception mode on days when the company is closed, such as Sundays, public holidays, and vacation periods such as year-end and New Year holidays. For example, the dispatch day is am9
: Set manual call receiving mode at 00:00, and set automatic call receiving mode at 6:00 pm. On days when the company is closed, the incoming call mode is not set, so the automatic incoming call mode remains. Therefore, it is possible to avoid the conventional problem of missing a chance to receive an image.

In the embodiment described above, two types of automatic call reception/manual call reception setting times were considered. However, this number is arbitrary.

Further, in the embodiment described above, the effective date of the incoming call mode setting time 2 is specified by the year, month, day, and day of the week, and the logical sum thereof is used as a condition, but this specification method is also free.

[Effects of the Invention] As is clear from the above, the present invention has a manual call receiving mode and an automatic call receiving mode. In an image communication device that automatically receives image data based on incoming call detection, two time periods are set for receiving calls in either manual receiving mode or automatic receiving mode, and each The present invention adopts a configuration including an incoming call mode control means for incoming calls according to the incoming call mode, and an incoming call mode switching means for switching to an automatic incoming call mode if the operator does not respond for a predetermined time after checking the incoming call during the manual incoming mode time period. Therefore, even if manual reception is set by the reception mode control means, if there is no response from the operator for a predetermined period of time, the mode can be automatically switched to automatic reception mode. It is possible to provide an excellent image communication device that does not become unable to perform image communication in an unattended state.
