Abstract

PURPOSE:To memorize weekday information and to recognize a weekday when information comes by blinking a light emitting element of a relevant part of a display circuit so as to display weekday. CONSTITUTION:The receiver is provided with a clock circuit 1 with a weekday count function, a control circuit 3 including weekday and time display, an LED drive circuit 4 sending a drive signal including the weekday and time display to LEDs 76-81 and a memory circuit 5 memorizing weekday information. Then in order to implement weekday display through a time confirming window, a weekday information signal 1A from the clock circuit 1 is given to a control circuit 3, from which weekday information being a signal 3A is stored in the memory 5. Then the control circuit 3 reads the time information and the weekday information from the memory circuit 5 to control the LED drive circuit 4. In this case, an LED selection signal terminal 21, an LED blink selection terminal 22 and an LED drive signal terminal 23 for signals outputted from the control circuit 3 are used as one group to form input signal terminals.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio selective calling receiver, and more particularly to a radio selective calling receiver having a function of being able to know the time and day of the received data.

[0002]

2. Description of the Related Art In a conventional radio selective calling receiver, as shown in FIG. 6, a radio circuit 65 detects an input signal to which its own selective calling signal is sent by radio waves, and a waveform shaping circuit 66 shapes it into a square wave. The comparison circuit 68 checks whether the data matches the data in the storage circuit 67. If they match, the control circuit 63 is notified of the match, and a sound signal is sent from the control circuit to the speaker drive circuit 70. A sound is emitted more and an LED drive signal is also sent to the LED drive circuit 64 to cause the LED to emit light. By turning on the reset switch 69A, the LED is turned off and the sound is stopped.
If the reset switch 69A is not turned on,
The control circuit 63 stops the light emission and sound of the LED after a certain period of time and stores the received information in the memory circuit 75. The information can be output to the control circuit 63 by turning on the reset switch 52 again, and the speaker 73 can emit a sound and the LED can emit light. Further, as a conventional example, in order to make it possible to know the time when the information is received by the light emission of the LED, the clock circuit 61 and the LED drive circuit 6 are provided.
4 and 6 LEDs 76 to 81 are provided. (For example, see Japanese Patent Application No. 2-33303.) Here, the LED drive signal sent from the control circuit 63 is sent to the LED drive circuit 64 together with the time information output from the clock circuit 61 connected to the control circuit 63. The LED drive circuit 64 has LEs capable of lighting two colors, for example, red and green, in one package.
Six D76 to 81 are connected, and the LED selected by the time information and the LED drive signal is turned on. In addition, the speaker 7 connected to the speaker drive circuit 70
A sound is emitted from No. 3, and by turning on the reset switch 69A, the selected LEDs 76 to 81 can be turned off and the sound of the speaker 73 can be stopped. If the reset switch 69A is not turned on, the control circuit 6
After a certain period of time, 3 stops the LED lighting and ringing and stores a ringing signal and time information in the memory circuit 75. The information stored in the memory circuit 75 is stored in the control circuit 63 by turning on the reset switch 69A again.
And outputs a sound signal and an LED drive signal according to the content of the information. The switch 69B is a clock correction switch, and when the switch is turned on, the clock circuit 61 is stopped at a predetermined time (for example, midnight), and the switch 62 of the clock circuit 61 is turned on. Was restarting.

[0003]

In the above-mentioned conventional radio selective call receiver, the time stored in the memory can be indicated by turning on the LED, but the time stored in the memory is stored because only the time is displayed. Even if the received information can be confirmed on the next day other than the reception day, for example, on the next day, there is a drawback that it is not known whether the information is yesterday's information or today's information.

An object of the present invention is to provide a radio selective calling receiver capable of knowing a day of the week for indicating when the information is sent, not only when the information is received but also when the information is stored in the memory. To provide.

[0005]

SUMMARY OF THE INVENTION A radio selective calling receiver according to the present invention comprises a clock circuit for timing the time at which a selective calling signal is detected, a memory circuit for storing timing information of the clock circuit, and the timing information. In a radio selective calling receiver having a display circuit composed of a plurality of light emitting elements for displaying, the means for blinking the light emitting element at the corresponding portion of the display circuit to display the day of the week.

Next, the operation of this embodiment will be described. First, the state of day and time display introduced in the present invention is shown in FIG.
This will be described with reference to (d). 4A and 4B show the same time information during radio wave reception as in the conventional example. Midnight to 0
If it is between the 59th hour, it is lit at the position of the circle with the LED hatch, and is displayed in red indicating morning (FIG. 4 (a)). If it is between 7:00 am and 7:59 pm, it is lit in the hatched circle and is displayed in green indicating afternoon (Fig. 4 (b)). Next, the time information including the day of the week is shown in FIG.
This will be described with reference to (c) and (d). The information including the day of the week usually displays the day of the week information with respect to the time information read from the memory to distinguish it from today's information. In FIG. 4C, during the period from 3:00 am to 3:59 am on Tuesday (Tu), the hatched circle A blinks Tu green, and the hatched circle B lights red. That is, if only the time display is used, both circles A and B are lit in red, but circle A is a day of the week display, so the color is inverted to green and a blinking display indicating the day of the week is made. In FIG. 4D, if it is between 8:00 pm and 8:59 pm on Wednesday (We), the hatched circle C flashes We red and the circle D lights green. That is, the circle C has its color inverted to show the day of the week, and has a blinking display showing the day of the week. In order to display the day of the week on such a time confirmation window, the day of the week information signal 1A from the clock circuit 1 in FIG.
