JPH0783508B2 - Wireless selective call receiver - Google Patents

Description

The present invention relates to a wireless selective calling receiver with a pen type display function (hereinafter, abbreviated as pen type receiver).

[Conventional technology]

Conventionally, in this type of pen-type receiver, in order to display a message on the display unit after the call notification is stopped as shown in FIG. 2, a switch operation is performed to stop the call notification. It was necessary to perform the switch operation again in order to display the message.

[Problems to be Solved by the Invention]

The conventional pen-type receiver described above must be operated by a switch to stop the call notification, and must be operated again to display the message content on the display unit. There was a drawback that the switch operation had to be performed twice in order to confirm the contents.

It is an object of the present invention to provide a radio selective call receiver that solves the above problems.

[Means for Solving the Problems]

In order to achieve the above object, a radio selective calling receiver according to the present invention has first means, second means and a control signal generating circuit, and continues to a selective calling signal composed of a digital signal. A radio selective calling receiver for receiving a message signal and optically displaying the content of the message signal on a display unit, wherein the first means has a structure for mounting the radio selective calling receiver in a pocket, The second means outputs a signal as to whether the receiver is mounted in the pocket or detached, and the second means is to make a ringing sound of the sounding element and blinking of the optical element and a message content by the display section. The control signal generating circuit is based on the signal from the first means by removing the radio selective call receiver attached to the pocket. Continuously generated twice set pulse, after stopping the second means by the reset pulse, is intended to display the message content to the display unit.

〔Example〕

 Next, embodiments according to the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment according to the present invention.

In FIG. 1, a radio signal received by an antenna 1 is amplified by a radio section 2 and then demodulated. The demodulated signal is exchanged by the waveform generation circuit 3 into a signal waveform that can be read by the decoder unit 4. The decoder unit 4 takes in the signal from the waveform shaping circuit 3 while synchronizing with the received signal by the reference clock made by the crystal unit 5, and compares it with its own calling number previously written in the P-ROM 6. If they match, a sounding drive signal is sent to the driver 7 as having been called, the speaker 8 is driven, and a message signal following the CPU 12 is sent out. The CPU 12 decodes the message signal, and the decoded message signal is stored in the RAM 13 and drives the LCD driver 15,
The LCD 16 provides a message signal as visual information.
The reset switch 9 stops the notification operation and displays or erases the message content. The clip 11 has a structure for mounting in the pocket, and judges whether the pen-type receiver is mounted or removed in the pocket and sends a signal to the reset signal generating circuit 10. The reset signal generating circuit 10 is a circuit that can generate the reset pulse twice in succession only when the notification operation is being performed and the pen type receiver attached to the pocket by the clip 11 is removed. Has become. Switch 14
Is connected to the CPU 12 and used for information processing operations.

FIG. 2 is an operation timing chart of the conventional pen type receiver. FIG. 3 is an operation timing chart of one embodiment according to the present invention. In addition, both of them are only main parts relating to the present invention, and other parts are omitted.
As shown in FIG. 2, in the conventional pen-type receiver, in order to stop the notification operation during the call notification operation and display the message contents, the reset switch operation is performed once to stop the notification operation and the message is displayed. While it is necessary to perform the switch operation twice in total for displaying the content, the pen-type receiver according to the present invention displays the message content by stopping the notification operation during the call notification operation as shown in FIG. In order to do so, the notification operation is stopped, and the notification operation is stopped by generating the reset signal twice in succession only when the pen-type receiver attached to the pocket by the clip is removed from the pocket. The contents can be displayed.

FIG. 4 is an external view of a pen-type receiver according to an embodiment of the present invention. 17 is a reset switch, 11 is a clip for mounting the pen type receiver in the pocket, clip 11
Is the detection unit 11a at the tip of the unit contacting the receiver main body 18?
Alternatively, it is determined whether the pen-type receiver is attached to the pocket or removed according to whether or not the pen-type receiver is in contact. Reference numeral 19 is a display unit.

〔The invention's effect〕

As described above, according to the present invention, the clip for attaching the pen-type receiver to the pocket determines the state of attachment or detachment to the pocket, and then generates the reset signal, so that the alarm operation is performed only by removing from the pocket. There is an effect that can stop and display the message contents.
