Description

  The present invention relates to an electronic apparatus provided with various operation means.

Conventionally, electronic devices such as wireless communication devices have been provided with various operation means such as operation knobs, dials, and switches. These operating means are configured so that effective operating information is input even if the operating force is small, based on the situation where miniaturization of the apparatus and simple operability are required. There are many things that have been done.
For example, there are encoder-type dials with light rotational torque, tactile switches with small push torque, etc., and they do not change the physical shape of knobs and knobs even if they are operated. The operator may not notice.
The operation result is often reflected as a status display on the indicator or other display means. However, if you have operated it unconsciously, you will not feel the need to check the status display. There is a problem that the user may not notice an erroneous operation without watching the status display.

  Therefore, in order to solve these problems, an electrical operation that is not desired by the operator, such as a dial lock function, is disabled and the lock is applied. Often equipped with a lock function.

  When it is desired to make an electrical operation valid while locked by the lock function, an operation for releasing the lock must be performed once, for example, an emergency operation is desired. In some cases, there is a problem that the operation cannot be performed quickly, especially when the operator is panicked and panicked due to an emergency, etc., and the lock is applied and the lock is released. It is necessary for emergency situations, etc., because it is difficult to perform proper unlocking operation because it is difficult to perform proper unlocking operation. Delays in response, and in the worst case, problems caused by the inability to operate itself become serious.

In order to facilitate the unlocking operation, JP-A-11-41165 (Patent Document 1), JP-A-8-321803 (Patent Document 2), and the like have been proposed.
Patent Document 1 discloses a technique related to a function for canceling the erroneous operation prevention mode of the telephone. When the operator turns on the touch sensor 7 by grasping the grip part of the telephone main body, any one of the key operation parts 2 is disclosed. A technique is disclosed in which the erroneous operation prevention mode is canceled for a predetermined time on the condition that the key is operated.
With such a function, it is possible to return to the normal mode and perform normal operations such as an incoming call response or an emergency call without inputting a release code by key operation of the key operation unit 2.
Patent Document 2 discloses a technique for setting or releasing a lock by a special operation of simultaneously pressing any two keys among a plurality of keys.

Japanese Patent Laid-Open No. 11-41165 JP-A-8-321803

In the technique described in Patent Document 1, the operator may inadvertently cancel the erroneous operation prevention mode simply by grasping the grip portion of the telephone body and operating any key of the key operation unit 2. There is. Furthermore, since the operation of holding the grip portion of the telephone body is necessary to cancel the erroneous operation prevention mode, it is difficult to apply the device operation to a device that does not perform the operation of grasping the body by hand. There is a problem that there is.
In the technique described in Patent Document 2, a special operation of simultaneously pressing any two keys out of a plurality of keys is necessary to release the lock, so that a panic occurs due to an emergency situation or the like. In such a state, the user is panicked and it is difficult to reliably perform such a special operation, and there is a problem that a situation in which the lock cannot be easily released occurs.

  Therefore, the present invention is made for the purpose of making it possible to release the lock by a repetitive operation or the like that is supposed to be performed in such a state even if a panic occurs due to an emergency situation or the like. It is a thing.

In the electronic device of claim 1 according to the present invention,

A lock function for disabling or prohibiting instructions for realizing the various functions by the operation means to be in a locked state, and releasing the locked state to be in a unlocked state Lock control means for controlling the unlocking function;
In an electronic device comprising a determining means for determining whether or not the lock is applied,
In the state where it is determined by the determination means that the lock is applied,
When the predetermined operation for instructing various functions is repeatedly or continuously performed from the operation means within a predetermined time, the lock control is performed so that the lock is released. An unlocking means for controlling the means was provided.
And in the electronic device of claim 2,
The operation means is a button operation type operation means configured to realize a predetermined function by pressing a specific part,
The unlocking means is configured to be in a unlocked state when the specific part is repeatedly operated a predetermined number of times or more.
And in the electronic device of claim 3,
The operation means is a dial operation type operation means configured to realize a predetermined function by rotating a specific portion,
The unlocking means is configured to be in a unlocked state when the specific portion is continuously rotated by a predetermined rotation angle or more.

An electronic device according to the present invention is the invention of claim 1,
In a locked state, if a predetermined operation for giving an instruction to realize various functions is repeated or continuously within a predetermined time, the lock is released, so the lock is applied. Even if an emergency situation occurs and you panic and you can't remember the predetermined unlocking operation, you can release the lock and perform the expected operation Become. Therefore, it is possible to prevent a situation where the user cannot panic and perform an intended operation in an emergency situation.
Further, in the invention of claim 2, since the lock is released when the button operation type operation means is repeatedly operated over a predetermined number of times, the predetermined unlocking operation is recalled when an emergency occurs. Even if this is not possible, the button operation type operation means can be repeatedly pressed many times to release the lock and make the desired operation possible.
Further, in the invention of claim 3, since the lock is released when the dial operation type operating means is continuously rotated by a predetermined rotation angle or more, the predetermined unlocking operation is performed when an emergency situation occurs. Even if it cannot be remembered, by continuously rotating the dial operation type operation means, the lock can be released and the intended operation can be performed.

Hereinafter, an electronic device according to the present invention will be described in detail with reference to the drawings showing a wireless communication device as an embodiment thereof.
FIG. 1 is a front view showing the main part of the operation panel of the wireless communication device. In this figure, 1 is a wireless communication device, and its operation panel has a main dial 2 as a dial operation type operation means operated when setting a communication frequency, etc., locked or unlocked Lock key 3 that is operated in order to obtain a state of operation, push switch 4 as a button operation type operation means associated with a predetermined function among various functions, and operation means associated with various other functions Is arranged.

FIG. 2 is a block diagram of a main part of the wireless communication device 1. In this figure, reference numeral 10 denotes a CPU having a dial operation detecting function for detecting the rotation angle and generating operation information corresponding to the rotation angle when the main dial 2 is rotated.
The CPU 10 also has a frequency control function for changing the operating frequency of the wireless communication device 1 according to the rotation angle detected by the dial operation detection function.
The CPU 10 also has a control function for detecting that the push switch 4 has been pressed and realizing a predetermined function.
Further, the CPU 10 sets the locked state when the lock key 3 is continuously pressed for a predetermined time or more when the lock is released, and when the lock key 3 is locked. In addition, it includes lock control means for bringing the lock into a released state when the lock key 3 is pressed.
The CPU 10 also includes lock releasing means for releasing the lock when the main dial 2 is rotated by a predetermined rotation angle or more within a predetermined time.
Note that the setting and release of the lock of the operation means can be performed by any combination of the plurality of push switches 4, for example, without providing a dedicated key like the lock key 3.

The control operation of the lock control means by the CPU 10 and the control operation of the lock release means by the push switch 4 in the wireless communication apparatus 1 having the above configuration will be described.
After operating the push switch 4 to control a predetermined function, a lock is applied to prevent the push switch 4 from being unintentionally pressed and inadvertently controlling the predetermined function. May be set to state.
In that case, by continuously pressing the lock key 3 for a predetermined time or more, the lock control means by the CPU 10 is operated and locked.
Therefore, in a locked state, even if the push switch 4 is unintentionally pressed, a predetermined function associated with the push switch 4 is prevented from being controlled.

When it is necessary to control the predetermined function associated with the push switch 4 as in the case of an emergency situation, the lock switch 3 is originally pressed to release the lock, and then the push switch 4 is You have to press and control certain functions.
However, if an emergency situation occurs and a panic situation occurs, such an original unlocking operation cannot be performed, and the push switch 4 is pushed and repeatedly pressed many times.
In the conventional technique, the lock is not released by such an operation, but such an operation is an operation in which the same predetermined operation is repeatedly pressed more than a predetermined number of times within a predetermined short time. According to the present invention, the condition for unlocking is satisfied, the unlocking means by the CPU 10 operates, the lock is released, and the predetermined function can be controlled.

As a condition for releasing the lock, a predetermined time within a few seconds is set in advance, and the number of repetitions within the predetermined time is set to several times, for example, three times or more. Such a predetermined time and a predetermined number of times can be set in advance to a desired time and number of times by various setting functions such as a menu mode, and can be changed at any time.
If it is not within the set predetermined time, the lock is not released even if it is repeatedly pressed more than the set predetermined number of times.
Therefore, for example, when operating or moving other equipment, the body or clothes will not be inadvertently released by touching the operation means with low rotational torque or push torque, and the original lock will be applied. Even if the operator panics due to an emergency or the like while keeping the state kept, the lock can be released and the predetermined function can be controlled.

The control operation as described above will be described with reference to the flowchart of FIG.
When the lock is applied, in step S1, a setting time, which is a condition for releasing the lock, is set in a timer, an initial setting such as a predetermined number of times is performed, and a counter that counts the number of repeated key operations. The value is cleared and the timer is reset.
In step S2, the process loops until the push switch 4 is pressed. If the push switch 4 is pressed, the process proceeds to the next step S3.
In step S3, it is checked whether or not the operation of the push switch 4 is the first operation or whether or not the same push switch 4 is operated. If not, the process proceeds to step S4, the counter value and the timer are reset, and then the process proceeds to step S5. If it is the first operation or the same push switch 4, the process proceeds to step S5.
In step S5, it is determined whether or not a lock for preventing malfunction is applied. If the lock is released, the process proceeds to step S6. If the lock is applied, step S7 is executed. Proceed to
The step S5 executed by the CPU corresponds to the determination unit described in the claims.

In step S7, it is checked whether or not the timer for which the predetermined time is set is operating. If not, the process proceeds to step S8 to start the timer and then proceeds to step S9. Proceed to step S9.
In step S9, the counter value is added once and the process proceeds to step S10.
In step S10, the counter value is compared with the predetermined number of times (for example, three times). If the counter value is less than the predetermined number, the process returns to step S2.
In step S11, it is checked whether or not the timer value is within the set time. If it is not within the set time, the process proceeds to step S12, the lock is not released, and the operation of the push switch 4 is invalidated. If the timer value is within the set time, the process proceeds to step S13.
In step S13, the lock is released and normal processing set for the push switch 4 is performed.
At an arbitrary time after it is determined in step S11 whether to release the lock, the initial setting in step S1 is performed.

Next, lock release control by the main dial 2 will be described.
After the main dial 2 is operated and the operation frequency setting operation is completed, the main dial 2 may be locked to prevent the operation frequency from being changed unintentionally.
In that case, by continuously pressing the lock key 3 for a predetermined time or more, the lock control means by the CPU 10 is operated and locked.
Therefore, in the locked state, even if the main dial 2 rotates unintentionally, the operating frequency is prevented from changing while being fixed.

However, when it is necessary to communicate at a frequency different from the current operating frequency, such as when an emergency situation occurs, the main dial 2 should be operated after the lock key 3 has been unlocked. Operating frequency must be changed.
However, if an emergency situation occurs and the user panics, the main dial 2 cannot be operated and the main dial 2 continues to turn.
In such an operation, the lock is not released in the prior art, but such an operation is an operation that continuously rotates more than a predetermined rotation angle within a predetermined short time. According to the invention, the condition for unlocking is satisfied, the unlocking means by the CPU 10 operates, the lock is released, and the operating frequency can be changed.

As a condition for releasing the lock, a predetermined time within a few seconds is set in advance, and an angle continuously rotated within the predetermined time is set. Such a predetermined time and a predetermined rotation angle can be set in advance to a desired time and angle by various setting functions such as a menu mode, and can be changed at any time. In particular, in the case of a wireless communication device set to change the operating channel by operating the main dial 2, the operating channel may be set up by rotating the main dial 2 to the right and down by rotating left. . In this case, the lock can be set to be released when a rotation operation corresponding to an up or down operation of a plurality of channels, for example, eight or more operation channels is performed continuously.
If it is not within the set predetermined time, the lock is not released even if it is continuously rotated by the set predetermined rotation angle or more.

The control operation as described above will be described with reference to the flowchart of FIG.
When the lock is applied, in step S21, an initial setting is performed such that the set time, which is a condition for releasing the lock, is set in the timer, and the number of channel changes of the operation channel corresponding to the predetermined rotation angle is set. The counter value that counts the number of repeated key operations is cleared and the timer is reset.
In step S22, the process loops until the main dial 2 is rotated. When the main dial 2 is rotated, the process proceeds to the next step S23.
In step S23, it is determined whether or not a lock for preventing malfunction is applied. If the lock is not applied, the process proceeds to step S24. If the lock is applied, the process proceeds to step S25.
The step S23 executed by the CPU corresponds to the determining means described in the claims.

In step S25, it is checked whether or not the timer set with a predetermined time is operating. If not, the process proceeds to step S26 to start the timer, and then proceeds to step S27. Proceed to step S27.
In step S27, the counter value is added by one channel change, and the process proceeds to step S28.
In step S28, the counter value is compared with the channel change number (for example, 8 channels) of the operation channel corresponding to the predetermined rotation angle. If the counter value is less than the predetermined channel change number, the process returns to step S22, and the predetermined channel change number is exceeded. If so, the process proceeds to step S29.
In step S29, it is checked whether or not the timer value is within the set time. If the timer value is not within the set time, the process proceeds to step S30, the lock is not released, and the operation of the push switch 4 is invalidated. If the timer value is within the set time, the process proceeds to step S31.
In step S31, the lock is released, and the normal processing set for the main dial 2 and the operation channel up / down operation are performed.

As described above, even if the lock key 3 that is originally necessary is not pressed, an operation for repeatedly pressing the push switch 4 or an operation for turning the main dial 2 more than a predetermined rotation angle is performed. Since the lock is released by performing the above, even when the user is in a panic state, the lock can be released and a predetermined operation can be performed.
Therefore, even if an emergency occurs in the locked state and a panic occurs, the lock can be released and the intended operation can be performed. It is possible to prevent a situation in which operation cannot be performed.
In the above description of the control operation, the push switch push operation and the main dial rotation operation are described separately. However, in the case of a device in which both the push switch and the main dial are arranged on the operation panel. In the lock function state, after the process of determining whether the push switch is operated or the main dial is operated, the control process of FIG. 3 or FIG. 4 is performed based on the determination result. Just do it.
In addition to the usual unlocking of the lock function, the unlocking means can be provided, or only the unlocking means can be provided. In the latter case, it goes without saying that the operation of releasing the lock is simplified.

In Example 1, the electronic device according to the present invention is a portable wireless communication device,
The condition for releasing the lock is that the push switch 4 is repeated three times or more within a predetermined time, or the main dial 2 is continuously rotated more than the rotation angle corresponding to up / down of 8 channels within the predetermined time. It was set so that the lock was released when it was

The present invention can be applied not only to a wireless communication device but also to a remote controller, a control device, or the like that has a function of bringing a locked state.
