[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone suitable for a second generation cordless telephone and the like.

[0002]

2. Description of the Related Art Mobile phones, such as second-generation cordless phones, which can be used for a wide variety of purposes, are often used while being carried in business bags or handbags. In some cases, a slide lock switch that can be disabled is provided.

[0003] For example, while moving in a state in which an incoming call can be accepted, a key provided on a telephone body may be touched to make an outgoing call by mistake, or a power key may be erroneously pressed to turn off. It may be in a state. In such a case, the terminal remains in the calling mode or the power is turned off, so that even if there is an incoming call during the subsequent movement, it cannot be answered.

A lock switch is provided for the purpose of avoiding such careless erroneous operation. If the lock switch is turned on after the incoming call mode is set, even if a key provided on the telephone body is erroneously operated, the key operation is not accepted, and the corresponding processing is prohibited. Therefore, even if an erroneous operation such as the transmission key is pressed or the power key is turned off by mistake, the incoming call mode is always maintained.

[0005]

When an incoming call is received with the lock switch turned on, the lock switch is operated to release the locked state, and a call key or an extension key among the keys provided on the telephone body. By operating a predetermined key, the telephone is set to an off-hook state and a call state is set.

[0006] In the mobile phone provided with the lock switch as described above, in order to release the lock mode and put into a talking state, at least two hours after removing the phone from a bag or the like.
Key operation is required twice. The lock switch is usually located on the side of the phone,
In many cases, the call key and the like are arranged on the front of the main body. In such a case, the lock switch is operated with one hand, and then the call key or the like is operated with the other hand in most cases.

[0007] Therefore, it takes a surprisingly long time before an actual call can be made after an incoming call. In a mobile phone, it is preferable that this time can be reduced as much as possible.

Accordingly, the present invention solves such a conventional problem, and proposes a portable telephone capable of shortening the time from receiving an incoming call to a call mode.

[0009]

A portable telephone according to the present invention has a lock state setting / release means for setting and releasing a lock state in which all key inputs are invalidated and only the incoming call mode is valid. When the lock state is set by the lock state setting / release unit and the lock state is released by the lock state setting / release unit when there is an incoming call, the control unit immediately switches to the call mode.

[0010]

When the lock switch 30 as the lock state setting / release means shown in FIG. 1 is turned on, all key inputs provided on the telephone body 12 are invalidated as shown in FIG. You. Therefore, only the incoming call mode is valid, so that even if another key is pressed by mistake, there is no transition to the mode corresponding to that key.

When the lock switch 30 is on, there is an incoming call. Upon receiving the incoming call, the locked state of the lock switch 30 is released, and the communication mode is immediately set to enable a call with the caller. Thus, the lock can be released and the call mode can be selected simultaneously by one key operation, so that the operation can be simplified and shortened.

[0012]

Next, an example of a portable telephone according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic view showing an example of a mobile phone 10 to which the present invention is applied.
Denotes a telephone body, and 14 denotes a key operation unit, which includes function keys such as a call key and an extension key in addition to the ten keys (10 keys).

Reference numeral 16 denotes a display unit capable of displaying telephone numbers and simple functions. 18 is a receiver, 2
Reference numeral 0 denotes a transmitter, which is incorporated in the telephone main body 12. Reference numeral 22 denotes a transmitting / receiving antenna.

A lock switch 30 is provided on the side of the telephone body 12. As shown in FIG. 2, the power switch is also used as a power switch, a three-stage switch is used, and the right slide position (the lower side in FIG. 1) is a position used in a normal call mode. The lock mode (hold mode) is selected at the center slide position, and the power is turned off at the left slide position (upper side in FIG. 1).

When the power is off, it does not function as a telephone. This is to reduce power consumption when the telephone is not used. When a call key or the like is operated in the case where the call mode is selected, a call with the other party can be made, whereas the lock mode is a mode used in a call waiting state.

As described above, a portable telephone is often carried in a business bag or handbag in an incoming call waiting state (the telephone is set to an ON state). In order to be able to respond to the call, the lock switch 30 may be selected to set the communication mode.

If a key of the telephone is carelessly touched in such a standby state, the state becomes the same as the state in which the key is operated. Therefore, a lock function is provided to avoid this erroneous operation, and a lock switch 30 is provided. I have. When the lock switch 30 is set to the ON state, acceptance of a key input mode other than the incoming call is prohibited, so that even if a key is pressed by mistake, the mode does not transit to the key operation mode. The incoming call mode is always maintained.

FIG. 3 shows a specific example of the lock switch 30. A slide button 32 is provided so as to face through a through hole 34 provided on a side surface of the telephone body 12, and the slide button 32 is attached and fixed to a flat slide plate 36.
A slide operation member 36a having a U-shaped recess is provided on the lower surface side of the slide plate 36, and the operation member 36a
The operation element 38a of the switch main body 38 is disposed so as to oppose so as to engage with. Reference numeral 40 denotes a printed circuit board for mounting and fixing the switch body 38.

One end face of the above-mentioned slide plate 36 In this example, the left end face is extended by a predetermined length to form a lock 37 having a projection at the tip end. Correspondingly, a pair of recesses 42, 44 having different lengths are formed on the back side of the telephone body 12, and locked in the recess 42 on the right side when the slide button 32 is in the call mode and the lock mode. There is a child 37, and the mutual positional relationship is selected so that the lock child 37 faces the concave portion 44 when the power-off is selected.

Since there is a projection 46 between the recesses 42 and 44, the lock 37 cannot be slid to the recess 44 by colliding with the lock 37 by simply operating the slide button 32. In this case, it is necessary to push the slide button 32 and slide the slide plate 36 in a slightly floating state. Therefore, the lock mode (FIG. 2B) does not switch to the power-off mode (FIG. 2C) unless the pressing and sliding operations are performed to turn off the power.

The reason why the click motion configuration is employed is as follows. When a switch having a simple three-stage slide configuration is used as the lock switch 30, when the lock switch 30 is operated to enter the lock mode (locked state), the second stage (lock mode) may be erroneously performed depending on the force applied. ) To the third-stage (power off) switch position, the slide button 32 may be moved,
And sometimes I don't notice this. This is because the user thinks that the second stage has been set.

In this case, since the power of the telephone is turned off, it is impossible to respond to the incoming call even if it is received. In order to avoid such an unexpected situation, a lock switch with a click motion as shown in FIG. 3 is provided. In this case, the slide button 32 is not set to the third position with a slight force, so that a situation in which the power is turned off even though the lock mode is selected does not occur.

FIG. 4 shows an example of the communication control unit 50 provided in the mobile phone 10. 52 is a receiving unit for a call signal, 54
Is a transmitter for transmitting a call signal, and 56 is a synthesizer for determining a transmission / reception frequency, all of which are controlled under the control of a control unit 58 composed of a CPU.

The control unit 58 has the above-mentioned handsets 18, 2
The key operation unit 14 and the lock switch 30 are associated with each other, and various key inputs from the key operation unit 14 and the analysis of the selection mode of the lock switch 30 are performed, and the contents are displayed on the display unit 16 as necessary. Is displayed.

In a memory means 59 such as a ROM provided in the control section 58, in addition to a control program for controlling communication,
A program for executing control corresponding to the selection mode of the lock switch 30 described above is stored.

FIG. 5 is a processing flowchart 6 for executing a lock mode processing program among these control programs.
0 is an example.

When there is an incoming call, the selection mode of the lock switch 30 is checked (steps 62 and 64). When the lock switch 30 is in the lock mode of FIG. 2B, the unlocked state is determined (step 68). When the lock is released, the key input inhibition mode is released and all key inputs are accepted (step 68). 70).

Thereafter, the control signal for off-hook processing is transmitted to the base station (public relay station, home base station (base station) or office base station) (step 72). When the control signal is transmitted, a call state is established. When the call is terminated, an on-hook processing control signal is transmitted to the same base station (steps 74 and 76).

When the lock switch 30 is in the locked state and an incoming call is received, an operation to release the locked state is performed. At the same time, the off-hook operation is performed simultaneously with the release operation, and the line is immediately connected and the telephone call is made. Will be able to In other words, a call can be made by one operation of unlocking, so that the operation can be simplified and shortened.

In particular, when the lock switch 30 is
In the case where the lock switch 30 is attached to the side surface of the second key, the operation of releasing the lock switch 30 and the operation of the call key are conventionally often performed by separate hands, which is unexpectedly troublesome.
For example, when the mobile phone 10 is taken out of the bag and operated, the user has the bag in one hand, so the user must release the bag and operate the telephone, which is a troublesome operation. If the call operation can be performed only by releasing the lock of the lock switch 30 as in the present invention, there is no need to release the bag since it is a single operation, and the operation can be performed very easily.

When the lock switch 30 is not in the locked state, the off-hook state is checked after an incoming call (steps 62, 64, 78). When the off-hook state is set by operating a call key or the like, the process proceeds to step 72 to realize a normal call state.

Although the lock switch 30 shown in the above embodiment is a specific example in which the lock switch 30 is also used as a power switch, the lock switch that can be used in the present invention may be configured separately from the power switch. The mobile phone according to the invention can be applied to various cordless phones.

[0033]

As described above, the mobile phone according to the present invention is configured so that an off-hook operation can be performed at the same time by releasing the lock state at the time of an incoming call.

According to this, the time from when the lock switch is released to when the call is actually started can be shortened as compared with the related art, and two operations of the lock release and the call operation can be realized by one operation. It also has features such as easy operation and improved usability.
