TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mobile phone device.
[0002]
[Prior art]
2. Description of the Related Art With the development of wireless communication technology, small and lightweight portable telephone devices have become widespread, and it has become possible to communicate with anyone, anytime, anywhere. In such a mobile phone device, usually, it is often carried around in a user's pocket or bag, but at this time, a problem that an operation button arranged outside the device is operated. was there. For example, if an operation button for instructing a call is accidentally pressed while being carried in a bag, it is possible that the mobile phone goes off-hook and no incoming call is made. In addition, if one of the operation buttons is used to make a call to a pre-registered party, the operation button called so-called one-touch dial is erroneously operated, a call is made without the user's knowledge, and unnecessary call charges are incurred. There is also a problem that it will cause trouble or that it will cause trouble for the other party.
[0003]
Therefore, the user can arbitrarily lock and release the operation button, and when the operation button is locked, the operation button is invalidated even if the operation button is pressed until the unlock operation is performed. Telephone devices have been proposed. For example, Japanese Patent Application Laid-Open No. Hei 5-236070 (H04M1 / 00) analyzes the contents of button operations and, if the contents of button operations are button lock, sets the operation buttons of the telephone device to invalid, A telephone device configured to hold the locked state until a lock release button is operated is described.
[0004]
However, this conventional technique has a problem that a special operation is required for unlocking, and the operation is complicated. For example, if an incoming call is received while the operation button is locked, a prompt incoming operation cannot be performed.
[0005]
[Means for Solving the Problems]
The present invention has been made to solve the problems of the prior art, and includes an opening / closing unit, a first operating unit covered by the opening / closing unit, a second operating unit not covered by the opening / closing unit, and the opening / closing unit. A detection switch for detecting the opening / closing operation of the control means, a lock control means for controlling operation of the second operation means to be invalidated at least after a predetermined operation of the operation means, and without operating the operation means, The lock is released by the opening operation of the opening / closing means.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of a mobile phone device according to the present invention will be described below with reference to the drawings. FIG. 1 is a view showing the appearance of a mobile phone device according to the present invention. 5 is a call key for instructing a hook control at the time of calling or receiving a call, 6 is a disconnect key for instructing the end of the call, 7 is a display for displaying various information, 8 is a receiving speaker, 9 is a transmitting microphone, Reference numeral 10 denotes an antenna.
[0007]
Reference numeral 11 denotes a detection switch for detecting the opening / closing operation of the opening / closing lid 2. When the opening / closing lid 2 is closed, a projection 2 a integrally provided on the opening / closing lid 2 depresses the detection switch 11. A closing operation is detected.
[0008]
When the cover 2 is closed as shown in FIG. 2, the numeric keypad 3 and various function operation buttons 4 are covered with the cover 2 except for the call key 5 and the disconnect key 6. Usually, with the opening / closing lid 2 closed in this way, the portable device is carried in a pocket or a bag. When a call is received from a third party, the incoming call processing is performed by pressing the call key 5, and a call can be made. When making a call, the user opens the open / close lid 2 as shown in FIG. 1, dials with the ten keys 3, and then operates the call key 5.
[0009]
FIG. 3 is a block diagram showing a mobile phone device according to the present invention. In the figure, 12 is a radio section for demodulating a radio signal received by the antenna 1 and modulating a transmission signal at the time of transmission, 13 is a TDMA processing circuit for performing time division multiplexing, and 14 is a digital signal processing for processing a digital signal A circuit, 15 is an A / D and D / A converter, 16 is a control circuit for controlling the entire portable telephone device, and 17 is a lock control circuit that operates according to a flowchart described later.
[0010]
When making a call, after the call button 5 is operated, the telephone number of the other party is dialed using the numeric keypad 3, whereby a line is formed via the base station, and a call state is established. On the other hand, when an incoming call to the own station is detected in the standby state, the ringer informs the user of the incoming call, the incoming call processing is performed by the user operating the talk button 5, and the call is started. Reference numeral 4 denotes a function key for performing various functions.
[0011]
Next, the key lock operation of the mobile phone device according to the present invention will be described with reference to the flowchart shown in FIG. In the mobile phone device according to the present invention, after operating one of the ten keys 3 or the function keys 4 covered by the opening / closing lid 2, the opening / closing lid 2 is closed within a predetermined time, so that the opening / closing lid 2 is not covered. The key lock of the call key 5 and the disconnection key 6 is performed. The key lock of the call key 5 and the disconnection key 6 is released by opening the opening / closing lid 2. That is, in the flowchart shown in FIG. 4, after the operation of the function key 4 is determined in step 1 first, and when the closing operation of the opening / closing lid 2 is detected by the detection switch 11 in step 2, this is controlled by the control circuit. It is conveyed to 16. The control circuit 16 controls the lock control circuit 17, and as a result, the call key 5 and the disconnect key 6 that are not covered by the open / close lid 2 are locked in step 3, and the operation of these operation buttons is invalidated. Therefore, even if the portable telephone device is carried in a pocket or a bag in this state, even if the call button 5 which is not covered by the opening / closing lid 2 is pressed in some way, an erroneous operation of going off-hook occurs. Is prevented.
[0012]
Further, when the opening operation of the opening / closing lid 2 is detected by the detection switch 11 in step 4, the lock of the talk key 5 and the disconnection key 6 is released in step 5 by the operation of the control circuit 16 and the lock control circuit 17. Therefore, a normal calling operation can be performed.
[0013]
On the other hand, if the closing operation of the opening / closing lid 2 is not confirmed for a predetermined time (for example, 10 seconds) after the operation of the function key 4 is detected in step 1 (step 6), then the opening / closing lid 2 is closed. Also, the above key lock is not performed.
[0014]
If a call to the own station is detected during the key lock, the ringer is sounded to notify the user to that effect, and if the opening of the opening / closing lid 2 is detected thereafter, the key lock is released and the user is released. The incoming call processing is performed by the operation of the call key 5.
[0015]
Alternatively, the incoming call processing may be automatically performed by opening the opening / closing lid 2 while the ringer is sounding, or by operating the call key 5 while the ringer is sounding. .
[0016]
【The invention's effect】
As described above, the mobile phone device according to the present invention can release the key lock by opening the opening / closing lid, so that when the user performs the operation intentionally, without performing the operation of releasing the key lock, Desired processing can be performed. For example, a call can be started promptly even when an incoming call is received.
