きない。2. Description of the Related Art A selective calling device is known which receives a selective calling signal transmitted from a base station and selectively calls the owner of the device using sound, light, message display, etc. By the way, even if the owner of this selective calling device is within the receiving service area, if the user is in an area where selective signals cannot be received, such as in a subway, the selective calling device will be in a reception disabled state. Therefore, a selective call cannot be made to the owner of this selective call device.

る。[0004] Therefore, the conventional selective calling device of this type has the following features:
It is configured to detect this unreceivable state from the received electric field level of control signals for reception synchronization transmitted from the base station, and to display this on a display provided for displaying messages, etc. ing. Therefore, the owner of this selective calling device can know whether the device is in a state where it is unable to receive calls by constantly looking at the display on the display. but,
Due to the nature of how this selective calling device is used, it is impossible to constantly watch the display, and there may be times when this device is in an area where selective calling signals cannot be received and the device does not function as intended. However, if you do not notice this, you may not be able to answer calls from the base station.
In some cases, important calls may be missed.

For example, if you are on the subway, etc., and the receiver returns to the ground after a period of unreceivable reception without you noticing, the receiver cannot receive a call while the receiver is unreceivable. There was a problem in that it ended without knowing whether something had happened or not.

It is determined whether or not they match, and if they match, L
The ED drive circuit 9 is operated to cause the LED 11 to blink, and the speaker drive circuit 10 is operated to cause the speaker 12 to sound. This allows the holder of this device to recognize that he or she has been called.

み自機の無線回路を動作させるように構成されている。By the way, the selective calling device of this embodiment operates the radio circuit 2 intermittently in synchronization with the sending cycle of the selective calling signal from the base station, in order to prevent the consumption of the battery of the power source (not shown) as much as possible. It is configured to receive selective call signals intermittently. To further explain this operation, a base station (not shown) divides a plurality of selective call receivers to which selective call signals are transmitted from this base station into a plurality of groups,
It is configured to transmit a selective call signal for each group, and each selective call receiver detects a synchronization signal included in a control signal periodically transmitted from the base station and selects a group in which it is included. The device is configured to operate its own radio circuit only during the transmission period of the corresponding selective call signal.

これが受信判定回路4aにより判別されると、そのとき
の時刻を時計回路8より検出してRAM6に格納する。That is, a control signal periodically transmitted from a base station (not shown) is received by an antenna 1, and guided to a reception determination circuit 4a in a control circuit 4 via a radio circuit 2 and a demodulation circuit 3. The reception determination circuit 4a determines from the signal level (reception electric field level) of this control signal whether or not the own device is currently in a receiving state. Here, reception determination circuit 4
If it is determined by a that the device is not in a receivable state, that is, if it is determined that the reception is disabled, the clock circuit 8 detects the current time and stores it in the RAM 6. Then, this selective call receiving device becomes ready for reception again,
When this is determined by the reception determining circuit 4a, the time at that time is detected by the clock circuit 8 and stored in the RAM 6.

RAM6に格納される。Therefore, for example, when entering a subway or the like, and the received electric field level becomes low, this will cause the reception judgment circuit 4 to
a, the time at that time is stored in the RAM 6, and when the received electric field level recovers again, the time at this time is stored in the RAM 6.
