DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a layout of a portable telephone having a recording / reproducing function. The present invention also relates to a technique for improving the operability of a mobile phone and the visibility of a display.

[0002]

2. Description of the Related Art A recording / reproducing function provided in a portable telephone includes a voice recording function during a call, a function of reproducing an already recorded voice during a call and transmitting a reproduced sound to a call partner, and a function of recording during a call. There is a function to play back the contents after the call ends.

The layout of a conventional portable telephone is such that a speaker, a display display unit, a call key, a call end key, a dial operation key, a key operation unit including various function keys, and a microphone are all arranged in this order from the top in front of the telephone. They are concentrated. The detachable battery is located on the back of the phone, and the antenna is located on the top.

[0004]

The layout of a conventional portable telephone is such that a speaker, a display display unit, a key operation unit, and a microphone are concentrated on the front side of the telephone. In order to operate the operation keys, the telephone that is being pushed to the ear must be released from the face to interrupt the call and operate the keys. The addition of the operation keys related to the recording / reproducing function makes the display display unit and the key operation unit smaller, so that an improvement in operability and visibility cannot be expected in a small-sized mobile phone.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art, the present invention relates to a portable telephone having a recording / reproducing function, which is opposed to a first surface of a telephone housing in which a speaker and a microphone are arranged. Operation keys related to the voice recording function are arranged on the second surface on the opposite side.

Further, in the portable telephone according to the present invention, a speaker is arranged at an upper part of a first surface of the telephone housing, a battery is arranged at an intermediate part and a microphone is arranged at a lower part, and a display unit is arranged at an upper part of the second surface. A key operation unit including a call key, a call end key, a dial key, and operation keys related to a recording / playback function is arranged.

FIG. 1 is a layout diagram of a portable telephone showing one embodiment of the present invention. FIG. 1A is a front layout diagram of the telephone housing 1, FIG. 1B is an internal layout diagram viewed from the side of the housing 1, and FIG. 1C is a rear layout diagram.

As shown in the figure, a display display unit 2 is arranged on an upper portion of a first surface which is a front surface of a housing 1, and a call key, a call end key, a dial key, and a dedicated recording button related to a recording / reproducing function are provided on a lower portion. A key operation unit 3 in which various operation keys such as a play button and a telephone directory button are arranged is arranged. Housing 1
The speaker 4 is arranged on the upper part of the second surface, which is the back surface, the detachable battery 5 is arranged on the middle part, and the microphone 6 is arranged on the lower part. An antenna 7 is arranged on the upper surface of the housing 1. Each operation key can be sized to be easily operated. Therefore, the key operation of the call key, the call end key, and the dedicated operation keys related to the recording / reproducing function can be easily performed while the telephone is pressed against the ear. When the dial key is operated by the call key and the line is connected, the call can be started. When the call end key is operated, the connected line is disconnected. A series of operations can be performed without removing the telephone from the face, including operations, and the call time can be shortened, so that the call charge can be reduced.

The housing 1 contains a single main printed circuit board 8. The display display unit 2 and the key operation unit 3 are installed on the front surface of the housing of the printed circuit board 1, and the connection unit with the speaker 4 and the battery 5, the microphone 6, the wireless circuit, and the control are installed on the opposite back surface. A circuit section 9 such as a circuit, a recording IC memory, and a power supply circuit is installed. The display display unit 2 is particularly remarkable when an EL is used for the backlight. However, since the display display unit 2 and the speaker 4 are separated from each other, noise due to the backlight becomes difficult to hear from the speaker. In terms of control and control, almost no countermeasures are required.

[0010]

According to the present invention, the operation keys related to the recording / reproducing function are arranged on the second surface of the portable telephone housing opposite to the first surface of the telephone housing where the speaker and the microphone are arranged. With this configuration, key operations related to recording and playback can be performed without leaving the telephone pressed against the ear during a call. And the operation keys related to recording and playback,
Since the speaker and the microphone are arranged on the second surface opposite to the first surface, the operation keys can be increased and the operability is good.

According to the present invention, a speaker is disposed at an upper part of a first surface of a telephone housing, a detachable battery is disposed at a lower part of the telephone body, and a display unit is disposed at a lower part of the second surface. Various operation keys including a call key, a call end key, a dial key, and an operation key related to a recording / playback function are arranged on the display, so that a large display unit and a large key operation unit can be realized. Since the antennas are arranged apart from each other on the opposite surface facing the speaker, noise caused by the backlight of the display unit is difficult to hear from the speaker. Furthermore, since the operation can be performed while the telephone is kept pressed against the ear from the call origination to the end of the call, the call time can be shortened and the call charge can be reduced.
