Description

Detailed Description of the Invention

[0001]

The present invention relates to a PDA (Person)
The present invention relates to a data processing terminal device suitable for application to a personal data processing terminal, which is called “al Digital Assistant” and has a relatively small size for portable use.

[0002]

2. Description of the Related Art Conventionally, various personal data processing terminal devices called PDA, which are relatively small and portable, have been put into practical use.

In the case of this type of terminal device, various data processing can be performed based on data input by keys provided in this terminal device, characters can be displayed by the processed data, and a message received from the outside can be displayed. Such data can be displayed.

In this case, in the case of a terminal device called a PDA, since the terminal device itself is constructed in a small size, a circuit for receiving data is usually not built in, and another receiving device such as a telephone is connected. Then, the data received by this receiving device can be taken in.

On the other hand, this type of terminal device is provided with a card mounting portion called a card slot, and various data processing can be performed by using an IC card mounted in this card slot. Normally, the semiconductor memory in the IC card is generally used as an external storage means for data, but it can be used for other purposes depending on the configuration of the card that can be mounted.

For example, using this card slot,
It is conceivable to connect a carded receiver. As this receiving device, for example, a wireless calling signal receiving device called a pager device is used, and the message data received together with the wireless calling signal is supplied to the data processing unit in the terminal device through the card slot to receive the message data. It is conceivable to perform display processing.

By thus connecting the receiving device such as the pager device using the card slot, the data receiving device can be easily connected to the terminal device, and the usability of the terminal device is improved.

[0008]

However, when a wireless receiving device such as a pager device is connected using the card slot, there is a disadvantage that the receiving performance of this receiving device deteriorates. That is, normally, the card inserted in the card slot is stored in a state of hardly protruding from the terminal device, and the inside of the terminal device near the card insertion portion is shielded to prevent interference from the outside. The influence of waves and the mutual interference between the circuit of the terminal device body and the circuit of the card are not adversely affected.

On the other hand, the carded receiving device has a built-in receiving antenna. Even if an attempt is made to receive a radio signal with this built-in antenna, the surroundings of the card slot are shielded, so that it is transmitted from the outside. It is becoming difficult to properly receive the wireless signal. Therefore, it has been difficult to connect a wireless receiving device such as a pager device using the card slot of the conventional data processing terminal device of this type.

In view of the above points, the present invention has an object to enable good reception when a wireless receiving device is mounted in a card slot in this type of data processing terminal device.

[0011]

According to the present invention, as shown in FIG. 1, for example, a data input section 19 and a data input section 1 are provided.
In a data processing terminal device including a data processing unit 11 that processes data supplied from 9, a receiving antenna 41 arranged in an unshielded part of the terminal device,
A connection circuit for connecting the reception antenna 41 to the reception circuit of the reception device 50 connected to the data input section 19 is provided.

Further, in this case, the data input section is a card slot, and the receiving circuit of the card type receiving device mounted in the card slot is connected to the receiving antenna.

Further, in each case, when the receiving antenna and the receiving circuit in the receiving device are connected via the connecting circuit, the antenna in the receiving device is disconnected from the receiving circuit.

[0014]

According to the present invention, the receiving device connected to the data input unit is connected to the receiving antenna arranged in the unshielded portion of the terminal device, and the radio signal is satisfactorily transmitted through the receiving antenna. You will be able to receive.

In this case, since the data input section is used as a card slot and the receiving circuit of the card type receiving device mounted in this card slot is connected to the receiving antenna, the card type receiving device is used. The reception processing can be performed well.

Furthermore, when the receiving antenna and the receiving circuit in the receiving device are connected via the connection circuit, the antenna in the receiving device is disconnected from the receiving circuit, so that only the antenna prepared on the terminal device side is used. Good reception is possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

This embodiment is applied to a personal data processing terminal called a PDA, which is relatively small in size for portable use and has a structure as shown in FIG. FIG.
Reference numeral 11 denotes a central control unit (CPU) that controls the data processing of each unit. The central control unit 11 is connected to a ROM 12 that stores program data and the like and a RAM 13 that stores data that is input from the outside. There is.

Further, the central control unit 11 is connected to the display control unit 14 and the operation command processing unit 15 via a bus line. In the display control unit 14, the data supplied from the central control unit 11 is used as display data (bitmap data, etc.).
Based on the display data, the display drive of the liquid crystal display panel 21 that constitutes the display unit 20 is performed, and the liquid crystal display panel 21 is displayed as characters or figures.

A touch panel 22 is formed on the surface of the liquid crystal display panel 21, and the panel 2 is provided with a dedicated input pen or the like.
Various operations can be performed by touching the display of 2. The operation information of the touch panel 22 is discriminated by the operation command processing unit 15 and converted into operation data to be transmitted to the central control unit 11. In addition, the operation of the two keys 16a and 16b (disposed on the left and right sides of the display panel 21) provided in this device is also discriminated by the operation command processing unit 15 and is included in the operation data to be transmitted to the central control unit 11. To be converted.

A terminal section 18 and a card slot section 19 are connected to the bus line connected to the central control unit 11 via an input / output interface 17. By connecting the connectors of various external devices to the terminal portion 18,
Data can be transmitted to and from the connected external device. By inserting and connecting a data processing card such as a memory card into the card slot section 19, data processed in the data processing card can be read out to the central control device 11 side, or the central control device 11 can be read. Data can be transmitted from one side to the card side.

In this example, the card slot section 1
When the central control unit 11 determines that the pager unit to be described later is mounted on the card 9, an antenna switching signal is transmitted from the central control unit 11 to the control unit of the pager unit in the card slot unit 19 via the bus line. Is done.

Further, an infrared signal light receiving portion 31 and a light emitting portion 32 are connected to a bus line connected to the central control unit 11 via an infrared interface 33, and the infrared signal received (received) by the infrared signal light receiving portion 31 is received. Is converted into control data by the interface 33 and the central control unit 1
1, the control data output from the central controller 11 is converted into infrared data by the interface 33, and the infrared data is output from the infrared signal emitting section 32.

In this example, a receiving antenna 41 is attached outside the terminal device. That is, as shown in FIG. 3, the receiving antenna 41 formed of a rod-shaped metal conductor is attached to a predetermined position such as the upper side of the terminal device.
The antenna 41 is connected to a predetermined terminal in the card slot portion 19 by a shielded signal line as shown by a broken line in FIG.

Next, the card connected to the card slot portion 19 of this example will be described. In this example, as a card, a pager device called a pager is used. FIG. 2 is a diagram showing the configuration of the pager device, in which 50 denotes the entire pager device, and a built-in antenna 51 is provided inside.
The wireless signal received at 1 is supplied to one fixed contact 52a of the antenna changeover switch 52. This changeover switch 52
Is a central control unit (CPU) 55 in the pager device 50.
The switch normally controls the movable contact 52m to be connected to one fixed contact 52a. The other fixed contact 52b of the changeover switch 52 is connected to the first terminal 61 of the terminal portion 60 of the pager device 50.

Then, the reception signal obtained at the movable contact 52m of the changeover switch 52 is supplied to the reception circuit 53,
Reception processing is performed using a signal in a predetermined frequency band (a frequency band in which a radio calling signal is transmitted) as a baseband signal.
Here, for example, a signal in the 920 MHz band is received and processed. Then, the baseband signal obtained by the reception processing is supplied to the data demodulation circuit 54 to demodulate the data included in the reception signal. Then, the demodulated data is supplied to the second terminal 62 of the terminal portion 60. Regarding the reception processing in the reception circuit 53 and the demodulation processing in the data demodulation circuit 54,
It is performed under the control of the central control unit 55, and in some cases, the received data can be stored in a memory (not shown) connected to the central control unit 55.

The data input / output section of the central controller 55 is connected to the third terminal 63 of the terminal section 60. Further, although not shown, a button battery for supplying the power necessary for operating the pager device 50 can be attached to the pager device 50.

The terminals 61, 62, 63 of the terminal portion 60 on the pager device 50 side are provided with slots 19 when the pager device 50 is mounted in the card slot portion 19.
The first terminal 61 is in contact with a terminal connected to a signal line whose one end is connected to the receiving antenna 41, and the other terminals 62 and 63 are input / output terminals. The terminal for data transmission connected to the bus line side through the interface 17 is brought into contact with the terminal.

The pager device 50 thus constructed is
By mounting the card in the card slot section 19, the pager device 50 can properly receive the radio call signal and the like. That is, the pager device 50 is installed in the card slot unit 1
When the central controller 11 on the side of the terminal device determines that it is mounted on the device 9 (the central controller 55 on the side of the pager device 50).
Can be determined by communication via a bus line with the central control unit 11), and an antenna switching signal is sent from the central control unit 11 to the central control unit 55 on the pager unit 50 side via the bus line, the terminal of the card slot section 19, and the terminal 63 on the pager side. Supplied.
By supplying this antenna switching signal, the central controller 55 on the pager device 50 side performs switching control for connecting the movable contact 52m of the antenna switching switch 52 to the other fixed contact 52b.

When the change-over switch 52 is switched, the receiving antenna 41 on the terminal device side is connected to the terminal 61,
Since it is connected to the receiving circuit 53 via the changeover switch 52, the receiving circuit 53 can receive and process the radio signal received by the antenna 41. In this case, since the receiving antenna 41 on the side of the terminal device is arranged outside the terminal device, it is possible to satisfactorily receive the wireless signal regardless of the shield processing inside the terminal device and wirelessly call with high sensitivity. You will be able to receive signals.

Therefore, as shown in FIG.
When 0 is inserted in the card slot portion 19, even if the pager device 50 is almost completely inserted into the terminal device,
The reception antenna 41 on the terminal device side can be used to properly receive a radio signal, and the pager device 50 can be connected using the card slot section 19. Therefore, for example, data can be received without connecting to the data receiving device with a signal cable using a terminal for communication, and usability as a terminal device is improved.

When the pager device 50 is removed from the card slot portion 19, the changeover switch 52 is in the original state (that is, one fixed contact 52a side is connected) under the control of the central controller 55 in the pager device 50. Of course, we will return to.

Further, the data received by the central controller 55 side in a state where the card slot section 19 is not mounted (that is, the pager apparatus 50 alone) is stored in the card slot section 19 of the pager apparatus 50. At this time, it may be transmitted to the central control device 11 on the terminal device main body side. However, in this case, the pager device 50
Uses the built-in antenna 51 as a receiving antenna.

In the above embodiment, the central control unit 5 in the pager unit 50 based on the command from the terminal unit body side.
Although the antenna changeover switch 52 is switched by the control of 5, the switch may be mechanically switched by inserting it into the card slot portion 19 of the pager device 50. For example, when the terminal portion 60 comes into contact with the terminal on the card slot portion 19 side, some connecting member moves due to this contact so that the antenna changeover switch 52 is switched from one fixed contact 52a side to the other fixed contact 52b side. Then, the antennas may be automatically switched.
By doing so, it becomes unnecessary to supply the antenna switching signal from the main body side.

Further, instead of switching the antenna with the switch as described above, diversity reception may be performed by the antenna 51 built in the pager device 50 and the receiving antenna 41 on the terminal device side. That is, for example, as shown in FIG. 4, instead of providing an antenna changeover switch, both the signal received by the built-in antenna 51 and the signal received by the antenna 41 supplied through the terminal 61 are sent to the receiving circuit 53. Alternatively, diversity reception may be performed in which the signal is supplied and the signal that is successfully received by the reception circuit 53 is selected.

Further, instead of selecting the reception signals of both antennas, the lines to which the reception signals are supplied from both antennas are simply connected in the receiving circuit 53 so that the two antennas are connected at the same time. good. Even with this,
When the card is inserted into the card slot section 19, the periphery of the built-in antenna 51 is shielded, so the built-in antenna 51 hardly receives signals, and there is almost no possibility that the reception state is disturbed.

Further, although the receiving antenna 41 is arranged outside the terminal device in the above embodiment, it may be arranged inside the terminal device. However, it must be placed in a position where it is not shielded from the outside.

Furthermore, in the above-mentioned embodiment, the pager device mounted in the card slot portion and the antenna are connected, but they are connected to the data input portion prepared in the terminal device for connecting other communication devices. You may make it connect a communication device and the antenna by the side of a terminal device.

Furthermore, in the above-mentioned embodiment, the pager device for receiving the radio calling signal or the like is used as the receiving device, but a receiving device for receiving another wireless signal may be connected. For example, a receiving device for a message transmission system or a receiving device for a wireless telephone line (in this case, the transmitting device may also be built in the card and transmitted from the antenna 41) may be made into a card, and a card slot unit may be provided. It may be attached to.

[0040]

According to the present invention, the receiving device connected to the data input section is connected to the receiving antenna arranged in the unshielded portion of the terminal device, and the radio signal is transmitted through this receiving antenna. You will be able to receive well.

In this case, since the data input section is used as a card slot and the receiving circuit of the card type receiving device mounted in this card slot is connected to the receiving antenna, the card type receiving device is used. The reception processing can be performed well.

Further, when the receiving antenna and the receiving circuit in the receiving device are connected via the connection circuit, the antenna in the receiving device is disconnected from the receiving circuit, so that only the antenna prepared on the terminal device side is used. Good reception is possible.
