Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a communication device such as a mobile phone, a PHS, a telephone, and a communication terminal, and more particularly to a communication device, a mobile phone, and a telephone that can prevent an erroneous call due to an erroneous operation of a key.
[0002]
[Prior art]
Mobile phones, PHS, and telephones have functions such as a speed dial for calling a desired dial number with fewer key operations and a one-touch dial without directly inputting the dial number with a numeric keypad.
[0003]
The abbreviated dial function calls a combination of short numbers (for example, 0, 01, etc.) and a dial number previously registered in the combination of numbers by operating an off-hook (telephone) key.
[0004]
The one-touch dial function makes a call by operating a one-touch key and a off-hook key in which dial numbers are registered in advance. In this way, when a call can be made with few key operations, if a mobile phone or the like is placed in a pocket or bag, an erroneous operation occurs due to external pressure from the outside, and the call is made erroneously. There is. In order to prevent this, the prior art has a key lock method that disables most key operations other than the key that returns from the key lock state (see, for example, Patent Documents 1 and 2).

DETAILED DESCRIPTION OF THE INVENTION
Exemplary embodiments of a communication device, a mobile phone, and a telephone according to the present invention will be explained below in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing the configuration of the present invention. A telephone or the like is provided with a dial key composed of a one-touch key and a numeric keypad for designating a call destination and a call key for starting a call (for example, an off-hook key) .
[0020]
In the figure, a CPU (Central Processing Unit) 1 is a control means for controlling the apparatus or the entire system. The FROM 2 (rewritable nonvolatile memory) stores firmware for controlling the apparatus or the entire system, and the CPU 1 operates according to the program. Further, data that must be stored for system control is also stored in the FROM 2.
[0021]
The SRAM 3 (rewritable volatile memory) forms a work area necessary for the CPU 1 to operate, and is used by the CPU 1 as a temporary data storage device. Also, it functions as a buffer buffer for the FROM 2.
[0022]
As an example of the key operation interval measuring means 4 for measuring the time between one key operation and the next one key operation, when the CPU 1 detects the first key input to the key input unit 5, a timer for measuring time is set. A configuration in which the timer value when the next key input is detected is used as the output value of the key operation interval measuring means 4 can be considered. Further, hardware in which the time between key input events is measured by a timer or the like without using the CPU 1 directly may be used.
[0023]
The display unit 6 displays the operation contents and settings of the apparatus. Here, according to the present invention, the output value of the key operation interval measuring means 4 is less than or equal to the preset time Ts (when smaller than the time Ts), or the output value of the key operation interval measuring means 4 is preset. The call is not made at the time Tb or longer (when it is longer than the time Tb).
[0024]
The preset times Ts and Tb may be set from the beginning and cannot be changed, or may be set arbitrarily by operating the apparatus.
[0025]
For example, in the case of an abbreviated dial consisting of a combination of a single digit and an off-hook key, it is assumed that the time from pressing a numeric key (numeric keypad) to pressing an off-hook key is 0.5 to 2 seconds under normal use. = 0.3 seconds and Tb = 5 seconds. At this time, Ts assumes a case where a plurality of keys are pressed down almost simultaneously (although there is a time difference), and Tb assumes a case where it takes time from the first key press to the next key press. For example, it is assumed that the key is pressed down by external pressure in a bag or the like.
[0026]
Further, when an erroneous key input is detected, the calling operation may not be performed and the key lock state may be entered. In this case, thereafter, key operations other than the key operation for returning from the key lock state are invalidated. The return from the key lock state may be a predetermined key operation or may return after a set time. As a result, it is possible to solve the problem that the key lock state is entered without knowing and the return operation is necessary. You can also set the time to return.
[0027]
FIG. 2 is a flowchart showing an operation for preventing erroneous operation according to the present invention. The example shown in the figure shows a case of an abbreviated dialing method in which dialing is performed by a combination of a single digit number and an off-hook key.
[0028]
First, it is determined whether the numeric key of the key input unit 5 has been pressed (step S1). It becomes a loop that waits until it is pressed (step S1: No). After the numeric key is pressed (step S1: Yes), it is determined whether the off-hook key is pressed (step S2). It becomes a loop which waits until it is pushed (step S2: No). When the off-hook key is pressed (step S2: Yes), times Ts and Tb are detected.
[0029]
First, it is determined whether or not the actual time from when the numeric key is pressed until the off-hook key is pressed is equal to or less than the time Ts (step S3). If the actual time is less than or equal to time Ts (step S3: Yes), the process is terminated without making a call. When the actual time exceeds the time Ts (step S3: No), it is compared with the time Tb (step S4). If the actual time is greater than or equal to time Tb (step S4: Yes), the process is terminated without making a call. When the actual time is less than or equal to time Tb (step S4: No), a call is made (step S5) and the process is terminated.
[0030]
According to the above configuration, the actual time from when the numeric keypad is pressed until the off-hook key is pressed is not less than time Ts (for example, 0.3 seconds) and not more than time Tb (for example, 5 seconds). Only when the call is made, erroneous operation can be prevented.
[0031]
Actually, in order to distinguish between a case where each telephone number is called by operating the numeric keypad and an abbreviated dialing means, an operation after the off-hook key is pressed and a number is entered by the numeric keypad before that. It is distinguished by how many digits are. For example, when the abbreviated dial means is composed of a combination of two digits, a normal call is made when the number input is three digits or more and the off-hook key is pressed.
[0032]
Further, the communication device of the present invention can be configured to include key lock means for key-locking operations of the speed dial key and the off-hook key. In this case, the key lock means places the speed dial key in the key lock state when the control means restricts the outgoing call. The key lock means may be configured to release the key lock state after a predetermined time (Tf) elapses after the speed dial key is set to the key lock state.
[0033]
Thereby, when an erroneous operation is performed and a call is not made, the erroneous operation can be more reliably prevented by further setting the key lock state. The fact that an erroneous operation has occurred means that there is a high possibility that an erroneous operation will continue, so that the effect of such key lock can be obtained.
[0034]
The communication device of the present invention can be applied to a telephone, a mobile phone, a PHS, a mobile terminal with a communication function, a facsimile machine, and the like, and can apply the same processing as described above. The mobile phone includes a PHS and a mobile terminal with a communication function, and the phone includes a facsimile machine.
[0035]
Note that the method for preventing erroneous operation described in the present embodiment can be realized by executing a program prepared in advance. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
[0036]
【The invention's effect】
As described above, according to the present invention, by measuring the operation time of the dial key and the subsequent operation time of the off-hook key, when the time is less than or equal to the predetermined time, a call is made as an erroneous operation. Since this is not performed, it is possible to prevent erroneous operation and outgoing calls in an inadvertent state. Thereby, there are effects such as improvement in operability and portability regardless of the usage form.
