Abstract
Abstract A facsimile store-and-forward switching system which stores an image signal and an input time upon receiving a call from a transmitting facsimile terminal and transmits the stored image signal to a receiving facsimile terminal together with the input time and an output time, the input time and the output time being changed in accordance with the time difference between the transmitting and the receiving facsimile terminals, wherein the time difference is updated every hour on the hour taking account of summer time.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
129 words
In a facsimile store-and-forward switching system which stores an input time upon receiving a call, detects the area of a destination facsimile terminal from data relating to the subscribers, calls the destination facsimile terminal, adds the time difference stored in a time control table to the input time and an output time, and transmits the input and output times together with an image signal to the destination, an improvement comprising the time control table including a summer time period and a summer time deviation for each area and a time difference changing means actuated every hour on the hour for determining whether the destination area is in the summer time period and for finding the actual time difference by taking account of the summer time deviation during summer time.
Claim 2
Dependent Claim
58 words
An improvement as set forth in Claim 1 wherein said time control table stores a nominal time difference between the system clock and the local time of an area, the summer time deviation indicating the extent of time deviation from the local time during summer time, the summer time period, and an actual time difference for each area.
Claim 3
Dependent Claim
41 words
An improvement as set forth in Claim 2 wherein the actual time difference is the nominal time difference when the area is subject to summer time and the actual time difference is the nominal time difference plus the summer time deviation.
Claim 4
Dependent Claim
20 words
An improvement as set forth in Claim 3 wherein the actual time difference is updated every hour on the hour.
Claim 5
Dependent Claim
128 words
In a facsimile store-and-forward switching system which stores an input time upon receiving a call, detects the area of a destination facsimile terminal from data relating to the subscribers, calls the destination facsimile terminal, adds the time difference stored in a time control table to the input time and an output time, and transmits the input and output times together with an image signal to the destination, a method of changing the time difference comprising the steps of: storing a summer time period and a summer time deviation which indicates the extent of time deviation from a nominal time difference during the summer time period; and changing the nominal time difference to an actual time difference in accordance with the summer time deviation during the summer time period.
Claim 6
Dependent Claim
63 words
A method as set forth in Claim 5 wherein the step of changing the nominal time difference comprises the steps of setting the nominal time difference as the actual time difference when the destination area is not in the summer time period and adding the summer time deviation to the nominal time difference when the destination area is in the summer time period.
Claim 7
Dependent Claim
24 words
A method as set forth in Claim 6 wherein the step of changing the nominal time difference is repeated every hour on the hour.
