Description

  The present invention relates to an improvement in a data writing function for registering a name, a telephone number and the like in a telephone.

  In conventional telephones, if an interrupt operation such as an incoming call or power-off occurs while using the registration function, the registration function screen is switched to the incoming call screen or the power-off screen so that data such as name and phone number can be entered. Work or registration work is interrupted. For example, in the mobile phone device shown in the external view of FIG. 7, the input operation is performed by using the data input key A03 while switching between alphanumeric and “Kana” using the function key A02, and the registration key after input. The data input to the memory in the telephone by A01 is registered. The registered data is read by the call key A04. If an interruption occurs before entering the operation of pressing the registration key A01, that is, during the input operation by the function key A02 and the input key A03, all the data input up to that point during the registration will be lost. When resuming registration, all data had to be re-entered from the beginning.

  In conventional telephones, when an interrupt operation occurs as described above, all data in the middle of registration is lost. When resuming the registration operation, the registration operation must be repeated from the beginning. There was a problem that it was troublesome and the operability was bad. An object of the present invention is to solve such a poor operability in a conventional mobile phone and to realize an easy-to-use mobile phone.

  In order to achieve the above object, in the present invention, an input means for inputting unique information such as a telephone number or a user name, and an LCD (displaying the unique information input from the input means in order of input) And a storage means having a rewritable nonvolatile memory for storing the unique information input by the input means. The input means is a RAM or the like. Volatile temporary storage means is included, and when the power interruption or other interrupt processing signal arrives, the inherent information in the middle of input in the RAM is temporarily stored in the rewritable nonvolatile memory by temporarily transferring it. When restarting the specific information input process due to the end of the interrupt process, the fixed information in the middle of the input temporarily stored in the nonvolatile memory is used. Information is a telephone apparatus characterized by continuing the input process without repeating enter the unique information from the beginning by transferred to the RAM.

  According to the present invention, when a work interruption occurs due to an incoming call or power-off in the middle of registration work such as a name of a phone book or a telephone number, and the registration work is started again, the registration data is changed from the beginning and the registration process is started from the beginning. There is no need to do this, the data registration process can be resumed from the state immediately before the interruption occurred, and the recorded data can be reused, so that the operability is improved even when the same data is repeatedly input. .

  The present invention will be described below with reference to the drawings.

  FIG. 1 shows an entire embodiment of a processing system according to the present invention. The contents of the process 109 in FIG. 1 are shown in FIG. 2, and the contents of the process 110 are shown in FIG. Here, both the processing 109 and the processing 110 have the same configuration for both the name data input 109 and 110 and the telephone number data input 1091 and 1101, respectively. Therefore, the processing steps of FIG. 3 is applied to the process 1101 and the process 1101. FIG. 4 shows a basic configuration of a system that executes processing according to the present invention. Each of the above processes is executed by the MPU 201, and switching of each process and data input are executed by the key input device 202. Data in the middle of input is taken into the SRAM 204 and processed. However, when interrupt processing such as power-off or incoming call occurs, in the conventional data input method, data in the SRAM 204 being processed is erased and processing by interrupt is started. The For this reason, when the interrupt processing is completed and the interrupted data input is resumed, it is necessary to input again from the beginning. In the present invention, a rewritable nonvolatile memory (EEPROM) 205 is connected in parallel with the SRAM 204, and when interrupt processing (111 or 114) occurs, the interrupt processing content is displayed on the display device 203 such as an LCD and input. Data in the middle is temporarily saved in a nonvolatile memory (EEPROM) 205. Here, when the interrupt process is completed, for example, when the power is turned on and the input process is resumed, the data that was being input from the nonvolatile memory 205 is read out and re-input to the SRAM 204, and the data input operation is performed. Continue to resume.

  The embodiment of the present invention will be described below with reference to the flowchart of FIG. First, when the power is turned on (step 101), if the processing is interrupted by the interrupt processing before that, the data such as the name and the telephone number that have been saved in the nonvolatile memory 205 are not stored. The data is restored to the SRAM 204 (step 102), and the data input is waited (step 103). For example, a name input request screen shown in FIG. 5A is displayed on the display device 203 of FIG. In this state (step 103), if the key input by the operator (step 104) is "power OFF" (step 105), the contents of the SRAM 204 are saved after being saved in the nonvolatile memory 205 (step 106) and registered. When the process is completed, the power-off process is executed on the system side (EXIT). If the key input is other than “power OFF” and the subsequent input is a registration key (A01 in FIG. 7), name data registration processing is performed, and a key other than this registration key is input. Return to the state of waiting for key input (step 103) (step 107). When a call key (A04 in FIG. 7) is input following the registration key input (step 108), a call process (step 110) for reading data in the middle of input from the SRAM is executed, and the input process is continued. However, if there is an input other than the call key, the name is manually input (step 109), and the operator manually inputs it. If an interrupt process occurs during the process from step 105 to step 110, the process returns to the key input standby state (step 111), and the contents of the interrupt process are simultaneously displayed on the display device 203 (step 118).

  When the name registration process is completed and no interruption process occurs, the process proceeds to a telephone number registration process. A telephone number input request as shown in FIG. 5B is displayed and registered again by the operator. Key A01 is pressed (step 112). If any key other than the registration key A01 is pressed at this stage, the system waits for key input (step 104). When the registration key A01 is input and then the call key A04 is input (step 113), the call processing (step 1101) for reading the registration data from the SRAM 204 is performed. When there is a key input, manual input processing (step 1091) is performed. If an interruption process such as an incoming call occurs during the above steps, for example, the incoming call display screen shown in FIG. 6 is displayed (step 115), and the process waits for input. If there is no interruption due to an incoming call or the like, and there is an input of the registration key A01 by the operator (step 116), the process proceeds to the registration process (step 117). It becomes a state. If the operator does not input the registration key A01 (step 116), the process immediately returns to the key input waiting state (step 103).

  FIG. 2 shows the contents of the manual input process 109. In the figure, START is connected to the call key input (step 108) in FIG. 1 in the case of name input, and the name key input (1093), name display processing (1094), and name data recording processing (1095) are repeated in order. When it is executed and the registration key (1092) is pressed at the end of the data input, the process exits from the input loop and proceeds to step (111) for checking whether or not registration interruption processing is output from EXIT.

  If there is no registration interruption input, the next telephone number input mode is entered. That is, when the registration key A01 is turned on in FIG. 1, the telephone number input mode is entered, and when the registration key A01 is turned off, the process waits for entry (112). If the mode is the telephone number input mode, the call key A04 is operated. If the key is ON, the process proceeds to the telephone number call process (1101), and if the key is OFF, the process proceeds to the telephone number manual input process (1091) (113). ). Here, the telephone number manual input process (1091) has the same configuration as that of the name input process (109) shown in FIG. 2, and in FIG. 2, START is connected to the operation (113) of the call key A04. The process proceeds to a check process (114) as to whether or not there is an incoming call during the operation process. In this case, in FIG. 2, the name key input (1093), name display processing (1094), and name data recording processing (1095) are not shown, but the telephone number key input, telephone number display processing, and telephone number recording processing are performed. Each process is performed. Each name and telephone number data recording process (1095) is a method of recording data on an SRAM (not shown) after being displayed on the LCD by data input.

  FIG. 3 shows a schematic flowchart of a registration data call processing procedure according to the present invention. First, in the case of the call processing by name (110), START is connected to the state where the call key A04 input (108) in FIG. 1 is ON, and after the name data extraction processing (1102) is executed, The extracted name data is displayed (1103) and displayed on the LCD. Here, whether or not the manual input is necessary is checked by correcting the extracted data (1104). If the manual input is not necessary, the process is terminated, and the process proceeds to the registration interruption check (111) in FIG. 1 through EXIT. Further, when performing a manual input operation, the name data input process shown in FIG. 2 is executed (1105). Calling from a telephone number is executed when the call key A04 is operated (113) and the key is ON.
