BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a portable radio apparatus of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a vibration and LE according to one embodiment of the present invention.
The external view of the wristwatch-type wireless selective call receiver (portable wireless device, hereinafter referred to as “receiver R”) that performs notification by D is shown. The receiver R includes a main body case 1 and a band B for mounting the main body case 1 on an arm. The main body case 1 has a cover glass 2 and a vibration motor 9 (FIG. 2) which is an example of a vibration device. (Refer to FIG. 4), the protruding portion 3 of the main body case 1, the LED 10, the switch button portions (operation switch means) 5a and 5b, and the liquid crystal panel (information display means) 6
And are arranged. The liquid crystal panel 6 shown in FIG.
The LED 10 and the LED 10 are shown as seen through the cover glass 2.

FIG. 2 is a sectional view taken along line XX of FIG. As shown in the figure, inside the main body case 1, there are provided a slot antenna 7 as an example of an antenna body, printed boards 8a and 8b on which a circuit group described later is mounted, a vibration motor 9, an LED 10, and an air battery 11. Each is arranged. Also, the back cover 13 is fitted on the back side,
A battery lid 25 is further fitted into the back lid 13.
Reference numeral 14 indicates the arm of the arm user. Further, the circuit group described above includes an IC molded body 150 in which a data decoder circuit and a CPU circuit are integrated, a chip element 151 for driving the IC, and chip elements 152 and 155 forming a wireless reception circuit. It is composed of an IC 153 that performs direct conversion reception. Also,
Reference numeral 154 indicates a shield case covering the local oscillation circuit.

FIG. 3 is an internal configuration diagram in which the surface of the main body case 1 of FIG. 1 is removed. The vibration motor 9 is arranged substantially parallel to the band B at the 9 o'clock position on the wristwatch, and when mounted on the left arm, the protrusion 3 of the main body case 1 does not hit the wrist and has a structure with excellent portability and wearability. Has become. Conversely, band B at the 12 o'clock or 6 o'clock position
When the vibration motor 9 is arranged in the direction orthogonal to the direction, the main body case 1 becomes too long in the direction from 12:00 to 6:00 and the wearability on the arm deteriorates. It looks large and has a heavy image, which is not preferable. Although the example in which the vibration motor 9 is arranged at the 9 o'clock position has been described in FIG. 4, an example of a product that is supposed to be mounted on the right hand is shown in FIG. In this case, the same effect as described above can be obtained by disposing the vibration motor 9 at the 3 o'clock position.

Further, as shown in FIG. 2, the vibration motor 9
Is a state in which the plastic member 4 is interposed on the upper side of the vibration motor 9 and the inner wall of the projecting portion 3 of the main body case 1 and the back cover 1
It is sandwiched between 3 and. The back cover 13 is easy to transmit vibration,
In addition, in order to ensure the durability of the battery lid 25, a hard material is preferable, and it is preferable to use polycarbonate or the like. Further, the shape of the back cover 13 on the side where the vibration motor 9 is arranged is complementary to the surface shape of the vibration motor 9. Although the cross-sectional shape is circular in the figure, if the surface of the vibration motor 9 is flat,
It is preferable that the planar shape has good adhesion, and if it is wavy, the wavy shape that meshes with it is preferable. Also, the arm 1 of the case back 13
4 has a flat arm contact surface 13a that comes into contact with the back cover 1
The end surface 13b of 3 is obliquely cut. As a result, the boundary portion between the arm contact surface 13a and the end surface 13b serves as an edge so that vibration can be easily felt, and at the same time, the main body case 1 looks thin when viewed from the side. As a result, when the vibration motor 9 operates to start vibration, the vibration is transmitted to the back cover 13 and efficiently transmitted to the arm 14 at the arm contact surface 13a.

FIG. 5 is a detailed view of part B of FIG. 3, showing the air intake hole 16. As shown in the figure, the air intake hole 16 is formed in the side surface portion of the projecting portion 3 in the main body case 1.
Is formed, and the air intake hole 1 inside the main body case 1 is formed.
A breathable waterproof membrane 15 is disposed in the opening of 6.
The receiver R has a structure in which water droplets and dust that are scattered from the outside and sweat that is transmitted from the arm are hard to enter. Specifically, FIG. 7 shows the position of the receiver R when worn on the arm and the direction in which water drops may be received.
The receiver R is likely to receive water droplets splashing from the directions 33, 34, and 35. In other words, if the user has washed their hands, or if they have a umbrella on a rainy day, the direction 33,
Water may be scattered from 34, and when drinking, the drink may be scattered from direction 35. However, the air intake hole 16 in FIG. 5 can prevent water droplets or the like scattered from all of these directions 33 to 35 from entering the main body case 1.

Next, a specific structure of the air intake hole 16 will be described. Although FIG. 8 is an enlarged view of the vicinity of the air intake hole 16, the convex portion 32 is provided near the air intake hole 16. Further, the bending direction of the air intake hole 16 is the direction 3
3 has an acute-angled intersecting relationship, and this configuration can prevent moisture from entering in the direction 33.

FIG. 9A shows the opening 1 of the air intake hole 16.
6a is a view of 6a as seen from the arrow E side in FIG. As the shape of the opening 16a, in addition to the circular shape, various shapes such as an elliptical shape and a configuration in which a lattice is put on them are conceivable. When the grid is attached, it is convenient because dust is hard to enter even though the area of the opening 16a is large.
Needless to say, a plurality of openings may be arranged in parallel as shown in FIG.

FIG. 10 is an enlarged view of the vicinity of the breathable waterproof membrane 15. The breathable waterproof film 15 is adhered to the projecting portion 3 of the main body case 1 with the double-sided tape 29, and is pressed by the cushioning member 30 from behind. The cushioning member 30 is a member that can fix the breathable waterproof membrane 15 from the back and allows air to pass through, and a sponge or the like is preferable. This prevents the breathable waterproof film 15 from peeling off even if an impact is applied from the outside of the air intake hole 16.

The breathable waterproof film 15 has a function of allowing air to pass through but blocking water, and operates by supplying oxygen in the air to the air battery 11 housed in the main body case 1. Even if the breathable waterproof film 15 is provided, it is preferable to set the air intake hole 16 at a place where it is less likely to be affected by the outside. Therefore, as described above, the air intake hole 16 is provided in the receiver R. It is formed at a position where water is least likely to be splashed when, for example, washing hands with the arm worn on the arm. Further, since the breathable waterproof film 15 can be stretched on the flat part of the case by forming it at this position, the assembling workability is good and the reliability against peeling is high. Further, since the air intake hole 16 does not linearly penetrate from the outside to the inside, the air-permeable waterproof film 15 may have a sharp tip from the outside.
Never be beaten.

FIG. 11 is a sectional view in the YY direction of FIG. The cushioning member 30 is also used as a pressing member for the vibration motor 9 in the axial direction. The provision of the air intake hole 16 on the side portion of the projecting portion 3 of the main body case 1 means that the cushion member 3
0 is used effectively in terms of space efficiency,
This is also extremely effective in reducing the size of the receiver R.

FIG. 6 is a detailed view of the portion A in FIG. 2, showing the periphery of the LED 10. In the figure,
Reference numeral 17 indicates the ink printed on the cover glass 2,
Reference numeral 18 denotes a portion that is not printed on the cover glass 2 and is a colorless transparent portion. When the LED 10 mounted on the printed circuit board 8a is lit by a lighting signal,
The LED 10 is provided through the colorless transparent portion 18 of the cover glass 2.
Light is emitted to the outside. This allows the user to know that there is received information addressed to himself by the light. The LED 10 is capable of emitting a plurality of colors, and an alarm drive circuit 107, which will be described later, outputs a lighting signal according to the content of the received information, so that the LED 10 emits light in a color according to the lighting signal. . Therefore, the color of the light allows the user to intuitively understand the approximate content of the received information, for example, whether it is an emergency contact or a normal contact. In addition, the cover glass 2 is a circuit internal element mounted on the printed circuit board 8a or the liquid crystal panel 6
Protects the vehicle from external shocks and also serves as a waterproof function.

By covering the liquid crystal panel 6 and the LED 10 with the cover glass 2 in this way, as in other internal parts of the main body, only one place between the cover glass 2 and the main body case 1 has a waterproof structure. Cover glass 2
It is possible to waterproof various parts underneath. If the LED 10 is arranged in a place other than the lower portion of the cover glass 2, it is necessary to provide an opening in the main body case 1 and to make the opening into another new waterproof structure. Compared with such a case, since the number of parts for the waterproof structure can be reduced in configuring the receiver R, the device can be downsized, and the parts for the waterproof structure and the mounting cost thereof can be reduced. can do.

Further, as can be seen from FIG.
Is disposed between the liquid crystal panel 6 and the switch button portions 5a and 5b. For this reason, the visibility is excellent, and the user can confirm the incoming information of the received information by the LED 10, confirm the content of the received information by the liquid crystal panel 6, and operate the switch button portions 5a and 5b without moving the line of sight. Can perform continuous actions. At the same time, even when the surroundings are dark, it is possible to know that some information is notified by lighting the LED 10 by the lighting signal. In addition, the LED 10 is located at a position easily associated with the switch buttons 5a and 5b located obliquely below the LED 10, and the light of the LED 10 illuminates the surrounding liquid crystal panel 6 and the switch buttons 5a and 5b. Therefore, the information received by the liquid crystal panel 6 can be easily confirmed, and the switch button unit 5 can be used at night.
In a situation where the positions of a and 5b are not clearly known, and when it is desired to stop the vibration of the vibration motor 9 when a notification is given, the switch button portions 5a and 5b can be operated easily and reliably by relying on the lighting of the LED 10.

FIG. 12 shows a sectional view of the cover glass 2 above the LED 10. LE on the cover glass 2
A protruding portion 2a, which is located directly above D10 and has a part raised outward, is formed. Since the protruding portion 2a has a lens effect and disperses the light of the LED 10, the user can surely know that the notification has been given even when the receiver R is viewed obliquely. In addition, the projection 2a scatters the light of the LED 10 to surround the liquid crystal panel 6 and the switch button 5
Since a and 5b are illuminated, confirmation of the contents of received information and switch operation can be performed reliably and easily even when the surroundings are dark.

FIG. 13 is a sectional view showing the structure of the switch button portions 5a and 5b (in the figure, the switch button portion 5a is shown as a representative). Switch button parts 5a, 5
Reference numeral b denotes a front button (switch button) 20, a coil spring 21 for making the pushing force of the front button 20 appropriate, and a retaining ring 22 for preventing the front button from coming off.
And a conductive rubber 23, respectively. When a force is applied to each of the switch button portions 5a and 5b from the direction C in the figure, the front button 20 is first pushed,
Along with this, the conductive rubber 23 is further pressed and two patterns (not shown) formed on the printed circuit board 8a come into contact with each other, thereby exhibiting the same function as the ON operation of the switch.

As described above, since the front button 20 is arranged on the front surface, the receiver R has excellent operability. Further, since the front button 20 is not arranged on the side surface of the main body case 1, the slot antenna 7 can be arranged along the inner periphery of the side surface of the main body case 1 (see FIG. 3). Therefore, as compared with the case where the operation switch is arranged on the side surface of the main body case 1, the antenna size can be increased, so that the reception sensitivity can be improved. In addition, since the slot antenna 7 is not punctured and the antenna performance is not deteriorated, the slot antenna 7 can have excellent antenna characteristics. In addition to the slot antenna, any antenna such as a loop antenna, a dipole antenna, and an inverted F antenna may be used as the antenna that circulates inside the body case 1. Can be secured.

FIG. 14 is an external view of the back surface of the main body case 1 in FIG. 1, showing a back cover structure. As shown in the figure, on the back side of the main body case 1, a back lid 24 and a battery lid 2 fitted to the back lid 24 and made of a plastic member.
5 are provided. FIG. 15 is a cross-sectional view taken along line RR of FIG. 14, in which the convex portions 25 a and 25 b of the battery lid 25 are fitted in the concave portions 24 a and 24 b of the back lid 24, respectively.
In the figure, the battery lid 25 is provided with convex portions 25a and 25b, and the back lid 2 is provided.
4, the recesses 24a, 24b are provided and fitted,
Conversely, if the battery lid 25 is provided with a concave portion and the back lid 24 is provided with a convex portion, the same effect can be obtained.

FIG. 16 shows a state in which the battery lid 25 is opened using the coin K. This back cover structure is shown in FIG.
As shown in, the battery lid 25 can be opened by inserting the coin K into the gap 26 between the convex portion 25c of the battery lid 25 and the back lid 24 and prying it open. When closing the battery cover 25, the battery cover 25 is pushed into the back cover 24. In this way, the battery lid 25 can be opened and closed without using a special tool or the like, so that the battery can be easily replaced.

FIG. 17 is a detailed view of portion D in FIG. 15, and reference numeral 28 is a rubber member formed on the outer periphery of the battery lid 25. The rubber member 28 makes it possible to provide waterproofness, and since it is integrated with the battery lid 25, the battery lid 25 can be opened and closed as compared with the case where a waterproof structure is provided by a separate O-ring packing or the like. There is no danger of being twisted or lost by operation. Further, according to the present embodiment, since only the battery lid 25 is removed when the battery is replaced, it is possible to cut the side portion of the main body case 1 obliquely like the end surface 13b in FIG. It is possible to realize an outer shape that more closely resembles that of a wristwatch.

Next, the electric circuit of the receiver R will be described.

FIG. 18 is a block diagram showing the circuit configuration of the receiver R. As shown in the figure, the receiver R includes the above-mentioned slot antenna 7, a transmission / reception radio unit 102 for transmitting and receiving radio frequencies, a waveform shaping circuit 103 for shaping the waveform of a received signal, and a control unit 105 described later. P-ROM on which the unique call signal to be compared in
(Programmable read only memory) 106,
An alarm drive circuit 107 for transmitting that the received information is stored, an alarm device 108 including a buzzer, an LED 10 or a vibration motor 9, and the switch button portion 5a described above for operating the radio R. , 5b and the liquid crystal panel 6 described above.
And a message processing unit 114 that controls each circuit of each of these units and processes received information. The message processing unit 114 controls the power supply control circuit 104 that controls power supply to the transmission / reception radio unit 102 and the waveform shaping circuit 103, the control unit 105 that controls the power supply control circuit 104 and processes received information, and temporarily receives information and the like. A RAM 109 for temporarily storing, an LCD drive circuit 110 for displaying the received information processed by the control unit 105 on the liquid crystal panel 6, and an oscillation circuit 111 for sending a clock signal used for controlling the LCD drive circuit 110. I have it.

Among these constituent elements, the transmission / reception radio section 102 and the waveform shaping circuit 103 are the same as those shown in FIG.
C153 and the chip elements 152 and 155, the message processing unit 114 and the P-ROM 106 correspond to the molded body 150, and the alarm drive circuit 107 corresponds to the chip element 151.

In the receiver R, a signal transmitted at a predetermined line frequency is demodulated by the transmission / reception radio section 102 via the slot antenna 7 and converted into a rectangular wave by the waveform shaping circuit 103. Electric power is supplied to the waveform shaping circuit 103 and the transmission / reception wireless unit 102 under control of the control unit 105 and the power supply control circuit 104 only during a time when a signal is received. The control unit 105 generates a battery saving timing signal for managing such power supply, controls the power supply control circuit 104, and performs bit synchronization and frame synchronization with the received signal. Further, the control unit 105 compares the peculiar calling signal recorded in the P-ROM 106 with the received signal supplied from the waveform shaping circuit 103 with error control, and the recorded peculiar calling signal is called. It is determined whether or not it has been hit. The control unit 105 also has a measurement function of measuring a signal from the oscillation circuit 111, which is a reference signal source such as a crystal.

In this case, when the call is confirmed, the reception information (message data) follows the unique call signal.
Is received and stored in the RAM 109. Then, the alarm device 108 informs the user via the alarm drive circuit 107 that the user has called. RAM
The message stored in 109 is the external operation unit 11
3 is operated to control LC via the control unit 105.
It is output to the D drive circuit 110, and the LCD drive circuit 110
Causes the liquid crystal panel 6 to display the received information while being controlled based on the clock signal output from the oscillation circuit 111.

FIG. 19 shows the alarm drive circuit 1 shown in FIG.
It is a signal waveform diagram of the alarm device drive signal output from 07. Here, the alarm device 108 uses the vibration motor 9 as a vibration device. When the control unit 105 reads the received code as the corresponding code, the control unit 105 immediately outputs the intermittent drive signal 200. The drive signal 200 has an on time t1 of 3/8 seconds and an off time t2 of 5/8 seconds. Then, the alarm drive circuit 107 repeatedly outputs the drive signal 200 for eight cycles, with this being one cycle. The vibration motor 9 intermittently transmits the vibration to the user by rotating for only the on-time t1 according to the drive signal 200. As a result, the user can surely know that there is received information addressed to himself.

By setting the ratio of the on-time t1 to the off-time t2 to this extent, the user can set the drive signal 20
Even if you do not notice it at the beginning of 0, drive vibration 200
Since the rising edge of is periodically generated, it is possible to surely know that there is received information. In this case, the duty ratio of the on time t1 in one cycle is set to 1/8 to 8 /
8 steps can be changed in 8 steps, and P-ROM 106
By changing the storage data of, the duty ratio can be easily set according to the preference.

20 and 21 show voltage change waveforms 202 at the end of the air battery 11 which are constantly observed by the control unit 105,
204 and the drive signal 200 of the vibration motor 9 are associated with each other. In this case, the end of the air battery 11 is
This is the time immediately before the nominal battery capacity is exhausted by continuous use. For example, air battery PR-2330
Has a nominal capacity of 850 mAh, and in this case, the end stage is when 700 to 800 mAh is used up. Time T
1 is the time for the control unit 105 to detect the battery voltage of the air battery 11. Actually, the time T1 is preset as 8 seconds after the output of the drive signal 200 is finished. Furthermore, the voltage 205 is the battery voltage lower limit (warning voltage) that the receiver can use, and
Stored in ROM 106.

At time T1, the control unit 105 compares the warning voltage 205 with the battery voltages 202 and 204, and if the battery voltages 202 and 204 are lower than the warning voltage 205, the operation of the transmission / reception wireless unit 102 is stopped, At this point, the transmission / reception wireless unit 102 cannot receive.

When the drive signal 201 has an on time t1 of 3/8 seconds and an off time t2 of 5/8 seconds as in this embodiment, as shown in FIG. It takes about 0.03v to recover the original battery voltage within a few seconds. Therefore, in such a case, the control unit does not stop the operation of the transmission / reception wireless unit 102 at time T1. Thus, the receiver R in this embodiment
Then, by intermittently driving the vibration motor 9 as shown in FIG. 20, the decrease in the battery voltage of the air battery 11 at time T1 can be reduced, and as a result, the battery capacity of the air battery 11 can be used up effectively. .

On the other hand, the ON time of the drive signal 203 is set to 8/8.
If the time is set to seconds, as shown in FIG. 21, the vibration is continuous for 8 seconds. In such a case, the vibration motor 9 has 60
A current of ˜70 mA flows, the battery voltage suddenly drops to 0.15 v due to the increase in internal resistance of the air battery 11, and it takes 5 minutes to return to the original voltage even after the end of vibration. In addition, the battery voltage of the air battery 11 at the end of no load is
It is about 1.1v and the decrease of 0.15v is a non-negligible amount. Therefore, in this case, the control unit 105
Stops the operation of the transmission / reception wireless unit 102 at time T1. However, in reality, after the time T1, the battery voltage of the air battery 11 returns to a voltage higher than the warning voltage. Therefore, the continuous drive of the vibration motor 9 as shown in FIG. 21 does not effectively use the air battery 11.
