Description




This application is based on Application No. 9-132296 filed in Japan, the contents of which are herein incorporated by reference.




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a data transmission apparatus such as a telephone, a facsimile or a copying machine having a facsimile function. More specifically, the present invention relates to a data transmission apparatus having a function of specifying, using a telephone number, a destination of data transmission through telephone circuit.




2. Description of the Related Art




Conventionally, a facsimile (or a copying machine having a facsimile function or the like) has been used for transmitting an image to a distant location through a communication circuit such as a telephone circuit. In the field of facsimile, one having an abbreviated dialing (speed dialing) function and one-touch dialing function, similar to the functions of a telephone, has been known.




The speed dialing function refers to the function in which for a telephone number which is dialed frequently, a train of numbers shorter than the telephone number is allotted (registered), and by inputting the abbreviated train of numbers and a prescribed key, the desired telephone number is dialed. The one-touch dialing function refers to the function in which a telephone number which is dialed frequently is registered at a prescribed key, and by pressing the prescribed key, the desired telephone number is dialed. One-touch dialing function is convenient, as the desired telephone number can be dialed by even smaller key operation than the speed dialing function.




The speed dialing function and one-touch dialing function save the labor in inputting all the digits of the telephone number through ten keys and prevents error in inputting the telephone number, when a desired telephone number which is frequently used is dialed.




In the field of telephone and facsimile, one having the function of counting the number of uses of the speed dial or one-touch dial (hereinafter also referred to as used number counting function) has been known. The number of dials which can be registered for the speed dialing function or the one-touch dialing function is limited, and therefore when one facsimile machine is shared by a number of users, the number of registrable dials may be insufficient. Further, it is often the case that a dial which is no longer used is kept registered, as it is not clear who uses the speed dialing or one-touch dialing, preventing efficient use of speed dials and one-touch dials.




In order not to reduce effectively usable speed dials and one-touch dials, the function of counting the number of dialing or use is utilized to monitor the number of dialing. Depending on the number of uses, registration of a dial which is not used may be deleted. Registration of a speed dial which is frequently used may be changed to registration of a one-touch dial, and registration of a one-touch dial which is used less frequently may be changed to registration of a speed dial.




In the above described conventional facsimile having the speed dialing function and one-touch dialing function, a telephone number registered for the speed dialing function may be switched for registration of one-touch dialing, utilizing the used number counting function, in the following manner.




First, the used number counting function is activated, and state of use of the speed dials and one-touch dials are monitored for a certain period. Referring to the state of use of the dials, telephone numbers of which registration should be changed from the speed dialing function to the one-touch dialing function are specified, and the specified telephone numbers are written in a memorandum. Thereafter, registration of these telephone numbers for the speed dialing function are deleted, and the telephone numbers are registered, referring to the memorandum, for the one-touch dialing function.




Though it is possible to change registration through the above described procedure, such procedure for changing registration is time consuming, and there is a possibility of erroneous input by the user during the operation.




SUMMARY OF THE INVENTION




The present invention was made to solve the above described problem, and its object is to provide a data transmission apparatus allowing change of registration of telephone numbers in a simple and secure manner.




The above described object of the present invention is attained by a data transmission apparatus in accordance with a certain aspect, which includes a storing section for storing a plurality of telephone numbers in correspondence with a plurality of dial registering sections, a designating unit for designating first and second dial registering sections of said plurality of dial registering sections, and a first control unit controlling the apparatus such that a telephone number corresponding to the first dial registering section is stored in the storing section as a telephone number corresponding to the second dial registering section.




According to another aspect of the present invention, the data transmission apparatus includes a first registering unit receiving as an input a first telephone number for registering the first telephone number at a first registering section, a second registering unit receiving as an input a second telephone number for registering the second telephone number at a second registering section, and a replacement unit for replacing the first telephone number registered by the first registering unit with the second telephone number registered by the second registering unit, without inputting the first or second telephone number.




According to the present invention, it is possible to have a content of an abbreviated dial moved another abbreviated dial by a prescribed operation, without directly inputting the telephone number. Therefore, unlike the prior art, registration of a telephone number can surely and easily be changed without the necessity for a user to perform time consuming and troublesome operation, and without the possibility of any error during the operation.




The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.

), a dial which is the object of dial registration is selected from the display, and thereafter, the flow proceeds to S


411


.




When there is no input for displaying the list (NO in S


407


), a dial designated by the user is input in S


409


, content of registration is displayed in S


410


, and thereafter, the flow proceeds to S


411


.




In S


411


, designation for dial registration replacement is input, and in S


412


, the content of dial registration displayed in S


402


is replaced by the content of dial registration displayed in S


408


or S

. After this process, the routine is terminated.




Based on the control described above, the following displays are given.





FIG. 5

shows displays given at the time of dial registration replacement. Here, displays given when registered content for a speed dial No. 5, which is frequently used, and registered content for a one-touch dial No. 3, which is not frequently used, are replaced, will be described. For speed dial No. 5, “XYZ STORE” as name of destination, “06-987-6543” as telephone number of the destination and “LOW” as communication speed of a modem are registered. For one-touch dial No. 3, “ABC CORPORATION” as name of the destination, “03-1234-5678” as the telephone number of the destination, and “HIGH” as transmission speed of a modem are registered.




Generally, a display


50


is given on display screen


15


of operation panel


1


(see FIG.

).




In the display


51


given on the display screen


15


, “OT-1” which is element


512


of the display represents one-touch dial No. 1. “BBS NET”, which is an element


512


of the display represents the name of the destination of the telephone number registered for the one-touch dial No. 1. “0 times” which is element


513


of the screen represents the number of use of one-touch dial No. 1. “CHANGE=YES” which is element


514


of the display represents that when the user presses YES key


18


, dial registration replacement is designated. “DEL=NO” which is element


515


of the display represents that dial registration is canceled or deleted, when the user presses NO key


19


.




When the user presses an arrow key


17


with the display


51


given on display screen


15


, then a display


52


of the second least frequently used dial (or of the same frequency as the last one) is given. By pressing the arrow key


17


several times, the display


53


is given which represents the number of use of speed dial No. 5, which is the object of the user, so that the user can confirm the number of use of the speed dial No. 5. Here, “SP-5” of display


53


represents speed dial No. 5.




In a state where the number of use of speed dial No. 5, which is the object of the user, is given in this example, when the user presses YES key


18


, it is confirmed that the registration content of speed dial No. 5 should be changed, and display


54


is given (which corresponds to S


406


of FIG.

).




With the display


54


given, whether a speed dial or a one-touch dial is to be designated for replacement of registration content with speed dial No. 5 is selected, by using left/right direction keys of arrow keys


17


and YES key


18


representing establishment. Here, with the display


54


given, YES key


18


is pressed, so that one-touch dial is selected.




Thereafter, display


55


is given, which asks the user to select whether direct pressing of a one-touch dial or display of the list of one touch-dials should be given. When YES key


18


is pressed here, display


56


is given. In the similar manner as for displays


52


and


53


, by pressing down key of arrow keys


17


several times, display


57

). Then one-touch dial No. 3 is pressed with the display


55


given, and the display


57


is given directly (which corresponds to the process when the answer is NO in S


407


of FIG.


4


). Whether the one-touch dial is to be directly pressed or the list of one-touch dials is to be displayed when the display


55


is given may be selected dependent on whether the user knows well the dial of which content of registration is to be replaced.




Display


57


represents number of use of one-touch dial No. 3, which is the object of the user. When YES key


18


is pressed, it is established that the registration content of on-touch dial No. 3 is to be replaced, and by display


58


, it is confirmed that the registration content should be replaced by that of speed dial No. 5, and the present setting is completed.




In this manner, the registered content of speed dial No. 5, that is, the name “XYZ STORE” of the destination, the telephone number “06-987-6543” of the destination and transmission speed “LOW” of the modem are replaced by the registration content of one-touch dial number


3


, that is, the name “ABC CORPORATION” of the destination, the telephone number “03-1234-5678” of the destination and transmission speed “HIGH” of the modem. Accordingly, the name “ABC CORPORATION” of the destination, the telephone number “03-1234-5678” of the destination and transmission speed “HIGH” of the modem are registered for speed dial No. 5, and the name XYZ STORE” of the destination, the telephone number “06-987-6543” of the destination and transmission speed “LOW” of the modem are registered for one-touch dial No. 3.




In this manner, it becomes possible for the user to surely and easily change registration of telephone numbers for the speed dials and one-touch dials, without the necessity of switching two telephone numbers through troublesome and time consuming operation, without any error in such operation.




It is possible to have an authorization ID input when dial registration is to be changed (when dial registration is to be deleted or replaced). The authorization ID is set in a manner as shown in FIG.

FIG. 7

is a flow chart showing control procedure for dial registration replacement, when it is possible to set the authorization ID for changing dial registration. The process shown in

FIG. 7

corresponds to the process of

FIG. 4

with some operations resulting from authorization ID added. Details of the process other than the portion related to the authorization ID are the same as those described with reference to FIG.


4


.




When the number of use of the dial registration is confirmed where it is possible to set the authorization ID, first, pressing of the used number conformation key


14


(see

FIG. 2

) is detected in S


701


. In S


702


, whether or not the authorization ID is set or not is determined. If the authorization ID is not set (NO in S


702


), the number of use of speed dials and one-touch dials are displayed in S


704


. Deletion and replacement of dial registration is allowed in S


705


, and the user deletes or replaces dial registration. Thereafter, the present routine is terminated. When the authorization ID is set (YES in S


702


), whether the authorization ID is correctly input or not is determined in S


703


. If the authorization ID has been input correctly (YES in S


703


), the control proceeds to steps S


704


and S


705


, in the similar manner as when authorization ID is not set.




If the authorization ID is not correctly input (NO in S


703


), whether setting


1


has been selected for authorization ID or not is determined in S


706


. When setting


1


has been selected (YES in S


706


), the present routine is terminated. If setting


1


is not selected (that is, when setting


2


has been selected) (NO in S


706


), the number of use of the speed dials and one-touch dials are given in S


707


, and the routine is terminated. In this case, it is impossible to delete or replace dial registration.





FIG. 8

shows displays given at the time of dial registration replacement when it is possible to set the authorization ID for changing dial registration. Displays shown in

FIG. 8

include displays shown in

FIG. 5

with displays related to the authorization ID added, and details of displays other than those related to the authorization ID are similar to those described with reference to FIG.


5


.




Generally, display


80


is given on display screen


15


of operation panel


1


(see FIG.


2


). When the user presses the use number confirmation key


14


, display


81


is given, asking input of the authorization ID (which corresponds to S


703


of FIG.


7


). When the user correctly inputs the authorization ID through ten keys


13


, the number of use of the registered dials are confirmed, and deletion or replacement of registered contents are performed as shown in displays


82


to


87


. When YES key


18


is pressed at the time of input of the authorization ID (display


81


), the process which can be performed by the user on the facsimile differs dependent on which of settings


1


and


2


is selected.




When setting


1


is selected and YES key


18


is pressed at the time of input of the authorization ID, the present routine is terminated without performing any of confirmation of the number of use of the registered dials, and deletion and replacement of the registration contents by the user (corresponds to the process when the answer is YES in step S


706


of FIG.


7


). When setting


2


is selected and YES key


18


is pressed at the time of input of the authorization ID, only the confirmation of the number of use of the registered dials is allowed for the user. After confirmation, the present routine is terminated (which corresponds to the process when the answer is NO in S


706


of FIG.


7


).




In this manner, by setting an authorization ID for changing dial registration, it becomes possible to manage the operation of the facsimile by a specific user, when the facsimile is shared by a number of users. Therefore, unnecessary deletion or replacement of registered contents for the dial registration by unspecified users can be prevented and hence the number of deletion/replacement of the registered contents for dial registration is not excessibly increased.




Though replacement between two registration dials have been described, it is possible to put in the contents of the dial registering section selected in step S


408


or S


410


to that dial registering section which is selected in step S


402


, in step S


412


of FIG.


4


.




Although the present invention has been described and illustrated in detail, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, the spirit and scope of the present invention being limited only by the terms of the appended claims.
