     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a communication apparatus, and more particularly to a communication apparatus having a console unit such as key entry switches for selecting one of various functions. 
     2. Related Background Art 
     Various types of electronic equipment have recently been advanced with regard to their functions and their performance. A facsimile machine is not the exception and a number of functions which have not been previously found in facsimile machines are now being attained. 
     As a result, an operation method or operation procedure of the machine is becoming fairly complex. 
     As to the operation method, there is a design philosophy that a number of functions are assigned to respective keys. In this case, however, the number of keys in a console panel increases very much. 
     In another design philosophy, key(s) for shifting or changing operation modes is provided and a plurality of functions are assigned to each key. In this case, the number of keys may be reduced but a complex operation is required to attain the same additional functions. 
     Those two prior design philosophies include the following problems. 
     1) In the former design philosophy, a number of keys are required for the console unit and the cost and the size of the machine increases. From the standpoint of users, only a small number of users utilize all functions of the recent high performance machine. Thus, the keys which are not normally used by the users are arranged on the console panel and the space is wasted. 
     2) In the latter design philosophy, the number of keys can be reduced, but when the user wants to select a desired function, the operation is complex and an excessive burden is imported to the user, or the function may not be actually used by the user even if the function is very useful to the user. 
     Applications relating to keys include U.S. Pat No. 4,502,080, U.S. Pat. No. 4,567,322, U.S. Pat No. 4,729,033, U.S. Pat No. 4,833,705, and U.S. Pat No. 4,908,853, but none of them solve the problems described above. 
     SUMMARY OF THE INVENTION 
     In the light of the above, it is an object of the present invention to improve a communication apparatus. 
     It is another object of the present invention to provide a communication apparatus equipped with key entry switches whose function can be set by a user as desired. 
     It is another object of the present invention to provide a communication apparatus having registration means for registering a key function as desired. 
     Other objects of the present invention will be apparent from the following description of the preferred embodiments and the accompanying drawings.

     FIG. 2 shows an enlarged view of the console unit 12 of FIG. 1. The arrangement of FIG. 2 is based on an arrangement of a conventional facsimile machine. Numeral 21 denotes an LCD panel through which the proceeding of the operation and the operation of the facsimile machine are informed to a user, numeral 22 denotes registration keys which are used to register functions selected by the user, and numeral 23 denotes a ten-key pad which is used to enter a telephone number. 
     Any number of registration keys 22 may be provided. Numeral 24 denotes a set key for setting a mode for the registration, numeral 25 denotes a clear key for clearing the registered mode, and numeral 26 denotes a selection key for selecting a desired one of several registration modes. Numeral 27 denotes one-touch keys. By depressing one of the keys 27, a telephone number stored in the RAM 15 is called. 
     Numeral 28 denotes a stop key which is used to terminate the operation of the facsimile machine, and numeral 29 denotes a start key to start a predetermined operation (such as transmission, reception or copy). 
     FIG. 4 shows a data store area in the RAM 15 of key function numbers registered in the registration keys 22. FIG. 5 shows a list of the registered key function number data and the corresponding function data. 
     In the present embodiment, the key function numbers 01 to 2F are preregistered, and the key function numbers 30 to 4F are reserved for use for the function expansion. The operator selects any desired key function numbers from the key function number data (sometimes referred to in the specification and claims as &#34;communication mode data&#34;) and registers them in areas 15-1, 15-2 and 15-3 in RAM 15, as shown in FIG. 4. 
     The function corresponding to the key function number 01 is, for example, the selection of alarm mode for missing transmittal. In the alarm mode for missing transmittal, if the number of sheets manually entered by the operator is different from the number of sheets actually transmitted, it is informed to the operator. 
     In the key function number 02, if a transmission error occurs, an error correction mode (ECM) is inhibited (ECM release) to prevent the selection of the ECM in which error data is automatically resent. 
     In the key function number 03, a forced memory receive mode is selected so that the received image is temporarily stored in the memory, and after the reception the image is read and printed out. 
     In the key function number 04, a dialing signal is switched from a pulse signal to a tone signal. 
     In the key function number 05, a sender name which the operator desires is selected from a plurality of preregistered sender names. 
     In the key function number 06, a mode to stamp the transmitted document sheet is selected. 
     In the key function number 07, a personal receive/personal transmit mode is selected. 
     In the key function number 08, a relay instructed transmission mode is selected. 
     In the key function number 09, a timer transmission/timer multi-address calling mode is selected. 
     In the key function number 0A, a timer polling receive/timer multi-polling receive mode is selected. 
     In the key function number 0B, a mode to register a telephone number to a one-touch dialing key or a present dialing key is selected. 
     In the key function number 0C, a mode to register a user telephone number or user abbreviation data is selected. 
     In the key function number 0D, a mode to register data to a user soft switch is selected. 
     In the key function number 0E, a mode to register data to a select button (not shown) is selected. 
     In the key function number 0F, a report output mode to record various reports such as a communication management report is selected. 
     In the key function number 10, the multi-address calling is stopped. 
     In the key function number 11, a cursor on the LCD panel 21 is moved. 
     In the key function number 12, a space is inserted between digits or characters to be registered. 
     In the key function number 13, a pause is inserted in the calling telephone number. 
     In the key function number 14, a telephone number of a data communication network is sent where the data communication network is used. 
     In the key function number 15, the registered data or menus are searched. 
     In the key function number 16, the items are set. 
     In the key function number 17, the data is cleared if wrong digits or characters are registered. 
     In the key function number 18, the registration of the current item is terminated and the registration of the next item is started. 
     In the key function number 19, the registration of data is terminated. 
     Other various key functions as well as their function numbers are also registered in the RAM 15. 
     FIG. 3 shows a registration control process of the registration key 22 by the CPU 11 of the machine shown in FIGS. 1 and 2. The process is stored in the ROM 14 as the control program for the CPU 11. 
     In a step S31, one of the registration keys 22 is depressed. In a step S32, whether any function has been registered in the depressed key or not is determined (00 indicates no registration of the function). 
     If it has been registered, the function is displayed on the LCD panel 21 (step S33) and the process stands by for a key entry in a step S35. If no function has been registered, selectable functions are displayed on the LCD panel 21 (step S34) and the process proceeds to the step S35. 
     In a step S36, if the depressed key is the selection key 26, one of the functions is selected by scrolling the function menu shown in FIG. 5 in a step S37 and the process returns to the step S35. In a step S38, if the depressed key is the clear key 25, whether anything has been registered to the registration key to which a function is to be registered is determined in a step S39. 
     If something has been registered, the memory area of the RAM 15 in which the function has been stored is cleared in a step S40, and the process proceeds to a step S37. If nothing has been registered, the process directly proceeds to the step S37. 
     In a step S41, if the depressed key is the set key 24, whether the selected function to be registered has been registered to another registration key or not is determined in a step S42. If it has been registered, &#34;Already registered in registration key OO&#34; is displayed on the LCD panel 21 in a step S43 and the process proceeds to the step S37. 
     In the step S42, if the selected function has not been registered in any registration key, the process proceeds to a step S44 to store the data of the key function number corresponding to the selected function in the memory area of the RAM 15 shown in FIG. 4. In a step S45, &#34;Registered&#34; is displayed on the LCD panel 21 and the process returns to the step S31. 
     In a step S46, a key entry time is managed, and if no key is depressed in a predetermined time period, the key entry timer is timed out and the process stands by in a step S47. 
     FIG. 6 shows a flow chart of a key entry control operation when the registration key 22 is depressed. 
     In a step S50, the presence or absence of a key entry is determined. If there is key entry and if there is a key entry for one of the registrations 1, 2 and 3 in steps S51, S52 and S53, the process proceeds to a step S55 and the data of the key function number corresponding to the registration keys is read from the RAM 15. If the entry key is other than the registration keys 22, the process proceeds from the step S53 to a step S54 and executes the process for the key entry. 
     In the step S55, the key function number data is read from the RAM 15. In a step S56, whether the key function number data is &#34;00&#34; or not is determined. If it is &#34;00&#34;, it means that the key function has not been registered and the unregistration of the depressed registration key is displayed on the LCD 21 in a step S57. Then, the process is terminated. 
     In the step S56, if the key function number data is not &#34;00&#34;, the data of the key function corresponding to the key function number data is read from the area of the RAM 15 shown in FIG. 5 in a step S58 and the data of the key function is displayed on the LCD 21. In a step S59, the key function is processed. 
     Assuming that the key function number data shown in FIG. 4 has been registered in the registration 1 key and the registration 1 key is depressed, the key function data &#34;02&#34; of FIG. 5 is read and the ECM release mode to inhibit the ECM is selected. Accordingly, in this case, the registration 1 key functions as an ECM release key. 
     In accordance with the present embodiment, the user selects the functions which a user may frequently use and registers those functions in the registration keys. Accordingly the operation is simplified, the number of keys in the console panel is reduced and the reduction of the cost and size of the machine is facilitated. 
     Since the user may select the functions which the user really desires to use out of the added functions of the facsimile machine, a small number of keys on the console panel may be effectively utilized, the waste is eliminated, the practice to operate the machine is ready, and the desired function can be input by a very simple operation. 
     In the above embodiment, the set key 24 and the clear key 25 are separately arranged although those keys may be shared with the start key 28 and the stop key 29. In this case, the keys on the console panel can be further reduced and the further reduction of the cost and size is attained. 
     While the facsimile machine has been described in the above embodiment, the present invention is not limited to the facsimile machine but it is applicable to various communication apparatuses such as a telex or a teletex. 
     The present invention is not limited to the above embodiment but various modifications thereof may be made.
