2. Description of the Related Art A reproduction-only tape recorder (Walkman, trademark of Sony), which has been developed for portable use, is well known. Furthermore, in recent years, portable telephone devices have also been miniaturized and portable telephone devices have become commercially available.

[0003] It is conceivable to integrate such portable electronic devices so that one electronic device can perform two functions.

As mentioned above, the Walkman is a mobile phone that has the same functions as the Walkman, or a similar video signal recording and playback tape recorder (Discman Sony trademark) developed for mobile use. Therefore, the function keys of the mobile phone must be attached to the housing.

As a result, in addition to the numeric keypad required for portable telephone devices, for example, a power on/off key, an on-hook key, a memo key, etc. are required, and a Walkman requires a play key, stop key, rec key, fast forward key, and rewind key. , requires a pause key, etc. For this reason, many operation key groups are arranged in a compactly configured housing.

[0006]

[Problems to be Solved by the Invention] As described above, the present invention
When at least two types of portable electronic devices are combined, the number of operation key groups that must be provided is minimized, so one key can serve multiple functions, allowing for unrestricted operation within a small space. The object of the present invention is to obtain a portable telephone device in which keys can be arranged.

[0007]

[Means for Solving the Problems] The portable telephone device of the present invention, as shown in FIG. It has a control means 9 that determines whether a call is in progress or not during a call when the playback key 12 is pressed.When the playback key 12 is pressed and a call is in progress, the call signal is recorded on the recording medium 3, and when the playback key 12 is pressed, the control means 3 records the call signal on the recording medium 3 when the call is not in progress. It is in playback mode.

[0008]

[Function] According to the portable telephone device of the present invention, by pressing the playback play key, during a call on the portable telephone, it acts as a memo key that automatically records the conversation during the call on the recording medium. However, when you want to listen to the Walkman, the switching means 1 is switched by the control means 9 to automatically enter the playback state, thereby acting as a play key, and since it can also be used as an operation key, the overall number of operation keys can be reduced. You can get something.

FIG. 3 is a perspective view of the appearance of the portable telephone device according to the present example, showing a state in which a call is made, and FIG. 4 is a perspective view of the appearance of the portable telephone device in a state in which it is used as a walkman.

In FIGS. 3 and 4, the housing 21 is a substantially rectangular box made of synthetic resin or the like and having an L-shaped side cross section. Contains control circuit. The starting and ending ends of this transmitting/receiving circuit are connected to the antenna 26 via a hinge part 29, and when the transmitting/receiving circuit is not in operation, the sub-casing 30 is folded into the housing 21 from the state shown by the broken line, as shown by the solid line in FIG. function as a Walkman.

A speaker 5 as a receiver, a power key 31, and a play key 11 are arranged inside the upper end of the panel 22 of the housing 21, and a plurality of through holes 24 are provided for emitting audio signals from the speaker 5. It is worn. As shown in FIG. 3, approximately the center of the panel 22 has a group of operation keys 23 such as a numeric keypad connected to a control circuit, and a hinge portion 29 is formed at the lower end of the panel 22. The sub-casing 30 is pivotally attached to the casing 21 via the sub-casing 30.

The sub-casing 30 is a substantially rectangular box made of synthetic resin, and has a hinge portion at the lower end of the narrow part of the casing 21, which has an inverted L-shaped side section as shown in FIG. It is pivotally connected via 29 so as to be rotatable. When the sub-casing 30 is open, the antenna 26 protrudes from the inside of the casing 21, and the sub-casing 30 is held at a predetermined angle by the locking mechanism of the hinge portion 29, making it easy to talk.

A transmitter 28 is disposed inside the lower end of the sub-casing 30, a through hole 25 is provided, and a mechanism for housing and driving a recording medium 3 such as a tape cassette is disposed at the upper end. It is set up so that it can be recorded and played back.

Next, as shown in FIG. 4, when the sub-casing 30 is folded from the broken line to the solid line to make the mobile phone 32 into a compact approximately rectangular state, the antenna 26 is housed within the casing 21. At the same time, on the back side of the sub-casing 30, a locking mechanism knob 35 for connecting and releasing the connection with the housing 21 appears, and a stop key 1 for functioning as a Walkman appears.
0, a rec key 12, a pause key 35, and fast rewind and fast forward keys 36 and 37.

In the portable telephone configured as described above, in the state shown in FIG. 4 where no transmission/reception, ie, communication is being performed, the sub-casing 30 is folded into the casing 21, and the antenna 26 is housed within the casing 21. Therefore, in this state, by inserting headphones into the headphone jack 34 and pressing the play key 11, the Walkman functions as a normal Walkman.

Next, when the knob 33 for the locking mechanism shown in FIG. It rotates counterclockwise and locks in place as shown by the dashed line. The antenna 26 is exposed on the upper surface side of the housing 21 in conjunction with the rotational movement of the sub-casing 30, and the antenna 26 is made ready for communication as shown in FIG.

In this state, it functions as a portable telephone, so the pressing hook switch 7 that was in the pressed state in the sub-casing 30 is released, and, for example, when the switch is activated, a microphone, which will be described later, is activated. It is transmitted as a control signal to a computer (hereinafter referred to as CPU).

The operation of the play key in the above configuration will be explained with reference to the system diagrams and flowcharts shown in FIGS. 1 and 2.

In FIG. 1, a call signal received through a telephone line, an antenna 26, etc. is supplied to the call input terminal T1. At the same time, the call state detection unit 8 detects call information from the call signal via the hook switch 7 and transmits it to the CPU 9.

The audio input terminal T2 is supplied with audio signals other than telephone calls, such as reproduction signals to be recorded on the recording medium 3 and other external signals.

[0023] Call input terminal T1 and voice input terminal T2
The movable contact a of the switching means 1 is connected to the fixed contacts b and c of the switching means 1, and the movable contact a of the switching means 1 is connected to the audio recording circuit 2 of a recording/reproducing device 6 having a recording medium 3, an audio recording circuit 2, and an audio reproducing circuit 4. be done.

The audio recording circuit 2 records audio signals and call signals on the recording medium 3 via a recording head etc., and the audio playback circuit 4 records the audio signals and call signals recorded on the recording medium 3 via a playback head etc. The music is picked up and emitted from the speaker 5, or the music played from a Walkman or the like is listened to through headphones via the headphone jack 34.

The CPU 9 is connected to the operating keys 23 such as the numeric keypad of the portable telephone 32 described in FIGS. and controls the recording/reproducing device 6.

In the above circuit configuration, the play key 11
The operation will be explained with reference to the flowchart in FIG. Figure 3
As shown in FIG. 3, when the sub-casing 30 is opened around the hinge portion 29, it is ready for a call, so the hook switch 7 is turned on, and the call state detector 8 detects the call information signal. is in a state of preparation.

[0027] Here, the CPU 9 performs the first step ST1.
As shown in , it is determined whether or not the play key 12 has been pressed, and if NO, the process returns to the beginning of the first step ST1, but if it is detected that the play key 12 has been pressed, the CPU 9 returns to the second step ST1.
Moving to T2, it is determined whether or not the wireless line is currently connected. That is, when the call status signal is detected from the call status detection section 8 and transmitted to the CPU 9, the process proceeds to a third step ST3, and if NO, the process proceeds to a seventh step ST7, which will be described later.

In the third step ST3, in order to record the digital signal transmitted from the line or the analog call signal demodulated by ADPCM on the recording medium 3, the switching means 1 is switched to move the contact a to the fixed contact b side. When the CPU 9 performs the tilting control, the call signal is automatically recorded on the recording medium 3 via the audio recording circuit 2.

Next, in the fourth step ST4, the CPU 9 determines whether or not the stop key 10 is pressed, as shown in FIG.
In the above, the stop key 10 is attached to the front surface of the sub-casing 30, but it can also be provided on the side wall of the casing 21, etc. This fourth
If the stop key 10 is pressed in step ST4, the process proceeds to a sixth step ST6 to end the recording operation, but if NO, the process proceeds to the next fifth step ST5.

In the fifth step ST5, the CPU 9 determines whether the call state signal from the call state detecting section 8 continues to be supplied or whether the call state signal has ended. The state in which the button is pressed and the state in which the call is terminated are continuously monitored.

If it is confirmed in the fifth step ST5 that the call has ended, the process proceeds to a sixth step ST6 to end the call recording on the recording medium 3.

If the CPU 9 determines in the second step ST2 that the phone is not in a call state, the process proceeds to a seventh step ST7, where the state is set to enjoy music on the Walkman, etc., and the recording medium 3
The audio signal is sent to the speaker 5 via the audio reproduction circuit 4.
and is output to the headphone jack 34.

[0033] In the eighth step ST8, stop key 1 is pressed.
It is checked whether 0 is pressed or not, and if YES, the process proceeds to the ninth step ST9 and ends the reproduction operation.

Sixth and ninth steps ST6 and ST9
After completion, the process returns to the first step ST1 and the same flow as described above is repeated.

According to the above configuration, when the play key 11 is pressed, it automatically operates as a memo recording key during a call, and when listening to an audio signal on the Walkman, it can be operated as a play key, and the play key and memo recording are activated. It can be used as a key, making effective use of small spaces.

In the above embodiment, a reproduction-only magnetic recording device has been described, but for example, a portable telephone device that integrates a magnetic recording/reproducing device capable of recording audio signals other than recording during a call and a portable telephone may include, for example, play key 1
1 and Rec key 12 are pressed at the same time, the CPU 9 checks the call state detection unit 8, and if it is not in a call state, switches the contact piece a of the switching means 1 to the fixed contact c side to prevent calls other than those input from the audio input terminal T2. The audio signal may be recorded on the recording medium 3 via the audio recording circuit 2. Further, the recording medium is not limited to a magnetic tape, but may be an optical disk or the like.

Although the switching means 1 described above is configured to give priority to telephone calls, it is clear that these may be selected in any manner by the software within the CPU 9.

Furthermore, although the hook switch 7 is linked to the opening and closing of the sub-casing 30, it is clear that the hook switch 7 may also be selected to be operated manually.

Since the present invention operates as described above, the play key functions as a memo recording key when used as a portable telephone, and functions as a play key for normal playback when used as a walkman. Since it is possible to do this, it is possible to obtain a key arrangement with relaxed restrictions.

[0040]

According to the portable telephone device of the present invention, since the same key can be used for multiple operation functions, restrictions on key arrangement can be relaxed in small-space devices, and an inexpensive device can be obtained.
