Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is used for a radio selective call receiver (hereinafter, referred to as a receiver) and a housing case thereof, and in particular, a closing operation and notification of a power supply of the receiver. The present invention relates to a receiver having an improved switch control circuit system for setting a stop of a unit, and a housing case thereof.

〔Overview〕

The present invention relates to a radio selective calling receiver, in which a carrier can set both a power closing operation and resetting a notification unit by opening and closing one switch, thereby preventing erroneous operation. It is intended to be downsized.

Further, a housing case compatible with the radio selective calling receiver of the present invention has been developed.

[Conventional technology]

In the conventional receiver, the housing has two switches, a power switch and a reset switch, and the control unit sets the power closing (on) and opening (off) operations of the receiver according to the state of the power switch, A setting was made to stop the operation of the notification unit depending on the state of the reset switch.

The receiver generally has components other than the control unit to measure the effective use of the battery used for the power supply, that is, the radio unit, the signal matching unit and the notification unit are placed under the control of the control unit,
Works as needed when needed. The radio section operates intermittently to receive information, the signal matching section operates only when comparing a call signal with a predetermined self-selection call signal, and the notification section receives a call. It works only when you check the received information.

[Problems to be solved by the invention]

The conventional receiver described above has the following problems.

In a conventional receiver, operation and non-operation are determined by a power switch set on a housing. It is up to the receiver to determine whether the receiver is waiting for a call. So when it becomes necessary to send information,
In some cases, the receiver is not in a state of waiting for the call, and the call cannot be made.

On the other hand, although the operation of the notification unit is stopped by the reset switch similarly set on the housing, there is a case where the wearer mistakenly operates the reset switch and the power switch, and the receiver cannot be called.

In addition, as receivers have become smaller year by year, two switches, a power switch and a reset switch, have to be mounted on the receiver, which has prevented the miniaturization.

SUMMARY OF THE INVENTION An object of the present invention is to provide a receiver capable of preventing the erroneous operation of a wearer and miniaturizing the receiver by solving the above-mentioned problems, thereby opening and closing the power supply and stopping the operation of the notification unit with one switch. Is to do.

[Means for solving the problem]

The receiver of the present invention is a reception collation unit that receives a selective call signal, detects a call signal addressed to the own receiver, and outputs a detection signal,
In a radio selective call receiver comprising: a notifying unit for notifying that a call has been made to a carrier; and a control unit for performing control including activation of the notifying unit by input of a detection signal from the reception collation unit. A switch and one control terminal representing an electrical first state and a second state by moving the position of the terminal, wherein the control means detects the state of the switch and the control terminal, and performs the control. Outputs a power-off signal when the terminal is in the first state and the switch is closed, and outputs a reset signal for stopping the operation of the notification unit when the control terminal is in the second state and the switch is closed. And a control circuit for setting a closing operation of the power supply by the close signal of the power supply and stopping the operation of the notification unit by the reset signal. .

Further, in the receiver of the present invention, the control terminal is attached to a concave portion provided in a part of a housing of the receiver, and when the terminal is pushed, the control terminal is in a ground state, and when the push is stopped, the control terminal is in an open state. Is preferable.

The receiving case of the receiver according to the present invention is provided in a part of a housing of the receiver, on a bottom surface of the receiving case where the receiver is stored, in a storing case that stores the receiver when the user does not carry the receiver. And a protrusion that fits into the recess and pushes up the control terminal.

[Action]

When the control terminal is in the first state (for example, the ground state) and the switch is in the closed state, the closing operation of the power supply is started, and when the control terminal is in the second state (for example, the open state) and the switch is in the closed state, the notification unit is activated. Can be reset.

Therefore, when the receiver is used, the control terminal is set to the first state before carrying, the switch is closed, the power is turned on, and then the control terminal is opened to carry the receiver. This allows the wearer to simply close the switch and reset the notifying unit, thereby preventing an erroneous operation. Further, only one switch is required, and downsizing is possible.

In addition, the receiving case of the receiver of the present invention automatically pushes the control terminal of the receiver by the protrusion to the first state. That is, when the switch is open, the power is turned off, and the power can be turned on by closing the switch. With this, when using the receiver, close the switch once in the housed state, turn on the power, then open the switch, remove the receiver from the housing case (the control terminal is automatically opened It will be good to carry it.
