Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable wireless device having a display section and an operating section.

[0002]

2. Description of the Related Art FIG. 15 shows a conventional mobile phone. The mobile phone 100 includes an antenna 110, a receiving section 120 including a speaker, and a transmitting section 13 including a microphone.
0, a display unit 14 composed of an LCD (liquid crystal display)
0, a numeric keypad 151 and an operation unit 150 composed of function keys 152, and the display surface 14 of the display unit 140.
1 displays simple information such as various modes of the telephone and dial numbers.

This mobile phone is configured to transmit information by voice with the other party, and this mobile phone is provided with a function as a terminal for fax communication or electronic mail, or as an electronic notebook, and these information It is very convenient for the user to display on the display surface 141 of the display unit 140.

In the mobile phone 100, however, the display surface 141 of the display unit 140 has a small area capable of displaying simple information. Therefore, when the mobile phone 100 is provided with the functions of various terminals, For example, when trying to receive a sentence such as an email, as shown in FIG.
Only the header part of the e-mail can be displayed. Therefore, the user has to repeat scrolling etc. to see all the information of the e-mail. You cannot do it.

On the other hand, like the mobile phone 100A shown in FIG. 17, the display unit 1 is assumed to be used as various terminals.
When the display surface 141 of 40A has a large area, the size of the display unit 140A becomes large, and the entire device becomes large, resulting in poor portability. Also, a large display surface 1
When the user has 41 but has a small amount of information to be displayed (for example, during a call), as shown in FIG.
Is displayed halfway, and the appearance balance of the display surface 141 is impaired. In this case, in consideration of the balance of the entire display surface, if an unnecessary screen pattern is displayed on the display surface 141 as shown in FIG. 19, unnecessary power is consumed, so a battery is used. ,
Therefore, this type of mobile phone, which should have low power consumption, is disadvantageous.

As described above, although the mobile phone 100A having the large display section 140A is much improved in usability and the amount of information that can be handled, it is mostly voiced in a normal use condition, so that a necessary display surface is required. However, the spread of the device has been hindered because it requires only a small area and is large in size as a whole so that it is inferior in portability.

[0007]

As described above, in the conventional portable radio apparatus, if the display section is made small with emphasis on portability, the amount of information that can be displayed is limited, so it is used as a terminal other than a telephone. In that case, there is a problem in that the operability is reduced. On the other hand, if an attempt is made to increase the size of the display unit to increase the amount of information that can be displayed, the overall size of the device becomes large and the portability is reduced. When the amount of information that needs to be displayed is small, there is a problem that the display on the display surface is halfway and the balance in appearance is impaired.

The present invention has been made in order to solve the above-mentioned conventional drawbacks, and is excellent in portability during a voice call or a stand-by state with a small amount of display information, and more information can be stored if necessary. An object is to provide a portable wireless device that can display.

[0009]

The invention according to claim 1 is
In a portable wireless device in which a display unit for displaying various information on a display surface and an operation unit provided with an operation switch on a predetermined surface are incorporated in a housing body, the display unit has the display surface as the housing. The operation unit is attached to the housing main body so as to face outward, and the operation unit is in a state in which a surface opposite to the predetermined surface is opposed to the display surface and is slidable along the display surface. It is attached to the housing body.

According to a second aspect of the present invention, in the first aspect, the operating portion is the entire display surface from the first position where only a predetermined area of the display surface of the display portion can be exposed to the outside of the housing body. Is slidable to a second position where it can be exposed to the outside of the housing body.

In the invention according to claim 3, claim 1 or 2
In the above, the housing body is provided with an operation unit position detection unit that detects the position of the operation unit with respect to the display unit.

[0012]

In the invention according to claim 1, since the operating portion is slidably provided on the main body of the housing so as to cover the display surface of the display portion, the area covering the display surface is slid by the operating portion. By changing the area, the area of the display surface exposed to the outside of the device can be changed.

According to the second aspect of the present invention, since the operating portion is slidable within a predetermined range from the first position to the second position, the amount of information displayed on the display portion is small as in a voice call. If not, by positioning the operation unit at the first position, only a predetermined area of the display surface of the display unit can be exposed to the outside, and it is necessary to display it on the display unit like e-mail. If there is a large amount of information,
By positioning the operation unit at the second position, the entire area of the display surface of the display unit can be exposed to the outside.

Further, according to the third aspect of the present invention, since the operating portion position detecting portion for detecting the position of the operating portion with respect to the display portion is provided, the signal from the operating portion allows the display portion to move to the outside of the device. It is possible to display information only in the exposed areas.

As shown in FIG. 1, the portable radio apparatus 200 of this example has a housing main body 210, an antenna 220, and an earpiece 2.
30, the transmitter 240, the display unit 250, and the operation unit 260 are incorporated, and when used as a telephone or when the amount of information that needs to be displayed on the display unit 250 is small, such as during standby, The area of the display surface 251 of the display unit 250 can be set to the same size as that of the conventional mobile phone 100 shown in FIG. 15. Therefore, the overall shape and size of the mobile wireless device 200 are also the same as those of the mobile phone 100. Can be something. On the other hand, the portable wireless device 200
When used as a terminal for AX communication or e-mail, or as an electronic notebook, as shown in FIG.
By sliding 0, the area of the display surface 251 can be increased, and thus a large amount of information can be displayed on the display unit 250. The configuration of each part will be described below.

As shown in FIGS. 6 and 7, the housing body 21
Reference numeral 0 denotes a lower cover 211 and an upper cover 212, and a battery storage portion 211a formed on the lower cover 211 side is covered with a battery cover 213. A main circuit board 270 and a sub circuit board 280 are housed in the housing main body 210, and the main circuit board 270 is mainly formed with circuit portions 271 that configure various functions of the apparatus.
A circuit portion that assists the main circuit board 270 is formed in the LCD, and an LCD (liquid crystal display) that constitutes the display portion 250,
The speaker 231 and the operation unit 260 that form the earpiece 230
A connection part (described later) and the like are provided.

The LCD which is the display unit 250 has a thin shape with a large area, and is provided on the sub-circuit board 280 so as to occupy most of the area on the surface 281 side of the sub-circuit board 280. . Then, this display unit 250
Of the display surface 251 is directed to the outside of the housing body 210, and the entire display area of the display surface 251 is exposed to the outside of the housing body 210 from the opening 212a formed in the upper cover 212. There is.

The operating portion 260 is the opening 2 of the upper cover 212.
It is formed in a thin plate shape having a width similar to that of 12a, and a numeric keypad 2 is provided on a predetermined surface 260a which is an outer surface of the device.
Operation switches such as 61 and the function key 262 are provided. Further, as shown in FIG. 11, a matrix-shaped circuit pattern 263 is provided inside the operation unit 260, and when the numeric keypad 261 or the function key 262 is pressed, any line Li (i = 1 to 4). And the line Ci (i =
1 to 4) are short-circuited. The reason why the circuit pattern of the operation switch is matrix-shaped is to reduce the connection portion with the sub-circuit board 280. When the operation switch has 16 operation switches as in this example, there are 8 connection portions. I wish I had it. In addition, a microphone 241 that constitutes the transmitter section 240 is embedded in the lower end side of the operation section 260. The microphone 241 may be directly attached to the sub circuit board 280, and a hole for sound transmission may be provided on the front surface side of the operation unit 260 or the housing body 210.

As shown in FIGS. 6 and 8, the operation portion 260 has step portions 264 formed on both edges thereof, and the step portions 264 are formed on the periphery of the opening 212a of the upper cover 212. The operation unit 260 is attached to the housing body 210 by being inserted into the groove 212d. Therefore, as shown in FIG.
The back surface 260e, which is the surface opposite to 0a, is the display unit 250.
The display unit 251 faces the display surface 251, and a part of the display surface 251 is covered with the operation unit 260 and is not exposed to the outside of the portable wireless device 200. Further, by sliding the operation unit 260 with respect to the housing body 210, the area of the display surface 251 exposed to the outside can be changed.

In this case, in this example, when the operating section 260 is slid upward in the direction in which the area covering the display surface 251 increases, the operating section 260 is moved to the step (first position) shown in FIG. The upper end of the portion 264 comes into contact with the end surface (not shown) of the groove portion 212d to prevent the sliding. Also,
When the operation unit 260 is slid downward in the direction in which the area covering the display surface 251 is reduced, the operation unit 260 is moved to the position shown in FIG.
At the position (2nd position) shown in, the protrusion 265 provided on the back surface 260e side abuts the upper edge of the lower cover 211 and is prevented from sliding. Therefore, in a mode in which the amount of information displayed on the display unit 250 is small, such as during a voice call, the operator simply slides the operation unit 260 upward, and the area of the display unit 140 of the conventional mobile phone 100 is reduced. The predetermined area of the display surface 251 having the same area can be exposed, and in a mode in which a large amount of information is displayed on the display unit 250 such as reception of an electronic mail, the operator moves the operation unit 260 downward. The entire area of the display surface 251 can be exposed only by sliding. Further, as shown in FIG. 8, when the operating portion 260 is in the first position and the second position, the operating portion 260 side has the convex portion 267 and the convex portion 267 has the upper cover 212 side.
It is configured to be fitted in 12e, and the operation portion 260 at the first or second position does not shift due to vibration or the like.

In this example, the operation section 260 is configured to be slidable between the first position and the second position in consideration of two cases, that is, the case where the amount of information to be displayed is small and the case where the amount of information is displayed is large. However, the present invention is not limited to this, and, for example, when the device is not used, the display unit 250 is replaced by the operation unit 26.
The operation unit 260 may be slidable to a position where it can cover the entire area of the display surface 251 of the display unit 250 so that it can be protected by zero.

The electrical connection between the operation section 260 and the sub-circuit board 280 is made by connecting the connection pattern 268 provided on the back surface 260e side of the operation section 260 and the connection pattern 26.
8 is made by an elastic contactor 283.

The connection pattern 268 of the operating section 260 is
As shown in FIG. 9, when the operating section 260 is in the first position, the pattern group connected to the contactor 283 (the pattern group in the row of (1) in FIG. 9) and the operating section 260 are the second group. The pattern group (the pattern group in the (2) row of FIG. 9) connected to the contactor 283 when in the position. The pattern group in column (1) includes patterns A1 and A3 (A1 and A3 are short-circuited) for detecting the operation portion position, and the line L of the matrix type circuit pattern.
Pattern Li, Ci corresponding to i, Ci, microphone 241
The pattern group having the connection patterns M1 and M2 and located in the row (2) is the operation unit position detection pattern A2.
A3 (A2 and A3 are short-circuited), line Li,
It has patterns Li and Ci corresponding to Ci and patterns M1 and M2 for the microphone 241. On the other hand, as the contactor 283 of the sub-circuit board 280, when the operating section 260 is in the first position, it contacts all the connecting patterns 268 of the pattern group (1), and the operating section 260 is in the second position. All the connection patterns 2 of the pattern group (2) at a certain time
The contactor PA for detecting the position of the operation unit so as to contact 68.
1 to PA3, contacts Li and PC for lines Li and Ci
i, contacts PM1 and PM2 for the microphone 241 are prepared.

Therefore, when the operating section 260 is in the first position, the connecting pattern 268 in the pattern group (1) is used.
However, by connecting the switches 261 and 262 and the microphone 241 of the operation unit 260 to the sub circuit board 280, the switches 260 and 262 of the operation unit 260 are electrically connected to the operation unit 260.
Is in the second position, the connecting patterns 268 in the pattern group (2) are connected to the contacts 283, respectively, so that the switches 261 and 26 of the operation unit 260 are connected.
2 and the microphone 241 are electrically connected to the sub circuit board 280. Further, as shown in FIG.
A voltage of Vcc is applied to the contacts PA1 and PA2 out of the three, and PA3 is connected to GND. Therefore, as shown in FIG. 10B, when the operating section 260 is at the first position, the output terminal X of the output terminals X and Y has the GND potential and the output terminal Y has the Vcc potential. Further, when the operating portion 260 is in the second position, the output end X has a potential of Vcc and the output end Y has a GND potential. In this way, the first position and the second position of the operation unit 260 can be detected. Further, when it is not located at any position, the output terminals X and Y both have the potential of Vcc. Incidentally, the microphone 241
When directly attached to the sub circuit board 280, the microphone patterns M1 and M2 and the microphone contacts PM1 and PM2 are attached.
Is unnecessary.

Next, a control method for switching the display area and display mode of the display unit 250 according to the position of the operation unit 260 will be described with reference to FIG. FIG. 5 shows a part of a control block diagram of the portable radio apparatus 200 of the present invention. 291 is a central control unit (CPU), 292 is a ROM storing a control program, 293 is a data work area, etc. RAM 294 used in the display unit, 294 a display control unit for controlling the display unit 250, 295 a VRAM for storing data to be displayed, 296 a key input control unit for controlling key input of the operation unit 260, and 297 an operation unit 260.

Reference numeral 98 is an operation unit position detection unit that outputs a position signal of the operation unit 260, and reference numeral 299 is a data bus.

The central control unit 291 controls the input / output control unit 297.
When inquiring about the current position of the operation unit 260, the input / output control unit 297 reads which of the output terminals X and Y of the operation unit position detection unit 260 is Vcc, and the operation unit 260 makes the first It is determined whether it is in the position or in the second position. Then, the central control unit 291 determines, for example, whether the display area of the display unit 250 is the predetermined area shown in FIG. 1 or the entire area shown in FIG. 2 based on the information of the input / output control unit 297, and this central control is performed. Based on the determination of the unit 291, the display control unit 294 causes the display unit 250 to display information in an appropriate area.

Since the portable radio apparatus 200 of this example has the above-mentioned structure, as shown in FIG.
By positioning 60 at the first position, the display unit 2
Only a predetermined area of the display surface 251 of 50 can be exposed to the outside, and information can be displayed only in the predetermined area. In addition, as shown in FIG.
By positioning 0 in the second position, the display surface 25
The entire area of No. 1 can be exposed to the outside, and information can be displayed in the entire area.

Therefore, during a voice call with a small amount of display information or during a standby, by arranging the operation unit 260 at the first position, the portable radio unit 200 can be made compact so that it is convenient for carrying and talking. In addition, as shown in FIG. 3, the display surface 251 of the display unit 250 has only a predetermined area as a display area, so that information can be efficiently displayed and unnecessary power is displayed. It is not consumed in the part 250.
