Abstract

PURPOSE:To attain excellent operability by outputting a reset or a protection signal from a duplicate depression detection circuit when a reset switch or a protection switch is depressed singly and erasing a signal from the duplicate depression detection circuit when both switch are depressed simultaniously. CONSTITUTION:A reset switch SW1 for call operation stop, a switch SW2 to set memory protection and a switch duplicate depression detection circuit 3 are provided on a radio call receiver 4 provided with a message display section 5. When the reset SW1 or the protection SW2 is depresssed singly, a reset or protection signal is singly outputted from the duplicate depression detection circuit 3 to stop calling or to protect memory in the receiver 4 in response to the singal. Moreover, when the reset SW1 and the protection SW2 are depressed simultaneously, the duplicate depression detection circuit 3 detects it and sends a delete signal to the receiver 4. Then the receiver 4 stops the calling or protects the memory. When both switches SW1, SW2 are depressed simultaneously, the curcuit 3 detects it to send a erasing signal to the receiver 4.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a radio paging receiver, and more particularly to a pager receiver that is equipped with a memory and has the function of storing and displaying received messages in the memory. , relates to a radio paging receiver in which the number of switches is reduced by detecting a double-pressing operation of two switches.

(Prior Art) A conventional pager radio paging receiver requires three switches: reset, protection, and erasure, as shown in FIG. Here, the reset switch is to stop the ringer, the protection switch is to protect the memory contents without writing the message to the memory at the next ring, and the erase switch is to erase the memory contents. It is for the purpose of For this reason, in devices that require miniaturization, such as radio paging receivers, the large number of switches becomes an impediment to miniaturization, and if you try to force miniaturization, the operability of the switches deteriorates. There was a problem.

In addition, in order to solve this problem, as shown in Figure 4, a mode switch is provided, and the operation of the reset switch is changed to erase, protect, and reset depending on the mode, so that one switch can perform three types of operations. There are also methods to achieve this. However, this method requires two operations: "mode selection" and "switch operation", and also requires a function to display the current mode on the display.
The disadvantage was that the message display area was reduced accordingly.

(Problems to be Solved by the Invention) The purpose of the present invention is to realize the three functions of reset, protection, and erasing with two switches by detecting double presses of the switch, and to realize the three functions of reset, protection, and erasure by detecting the double press of the switch. The object of the present invention is to provide a radio paging receiver that can be implemented in operation.

(Means for Solving the Problems) The present invention is characterized in that, in a display-equipped radio paging receiver having a display section for displaying a received message, a reset switch 1 for stopping the ringing tone and a memory for storing the received message at the next call are provided. a protection switch 2 that protects memory contents without storing them; the reset switch 1; and the protection switch 2;
A wireless ejection receiver with a display includes a double press detection circuit that generates an output and erases the contents of the memory when the buttons are pressed at the same time.

(Function) In the above configuration, when the reset switch is pressed alone, the reset operation is performed in the same way as in the conventional case, and when the protection switch is pressed alone, the operation is the same as that of the conventional protection switch. When the reset switch and protection switch are pressed at the same time, the double press detection circuit generates an output and erases the memory. Therefore, by providing only two switches, the same operation as the conventional three switches can be performed, multiple functions can be operated with fewer switches, and mode selection is not required. is different from conventional technology.

Note that when pressing two switches at the same time, a slight time lag between the presses does not become a problem because the switch operations are defined as described above, and the time lag between the presses causes undesirable operations. Never.

(Embodiment) FIG. 1 shows an embodiment of the present invention, in which 1 is a reset SW for stopping the calling operation, 2 is a switch for setting memory protection, 3 is a double-press switch detection circuit, 4 5 is a radio paging receiver with a display, and 5 is a message display section.

In this circuit, when the reset SWI or the protection SW 2 is pressed alone, a reset or protection signal is issued from the double press detection circuit 3, and the receiver 4 stops the calling operation in response to that signal. Or protect memory. Further, if the reset SW1 and protection SW2 are pressed simultaneously, the double press detection circuit 3 detects this and sends an erase signal to the receiver 4. The receiver 4 erases the contents of the message memory that receives the erase signal.

Figure 2 shows a specific example of a double press detection circuit, in which 1 is a reset switch, 2 is a protection switch, 13 and 14 are inverters that invert the logic of the signal, and 15 and 16 are AND circuits for detecting double presses. It is. When the reset switch 1 or the protection switch 2 is pressed, a positive logic signal is output from the inverter 14 or 13.

The protection signal is output as is, but the reset signal is 15
and 16 AND circuits before being output.

When reset switch 1 is pressed alone, a reset signal is output through 16 AND circuits, and when both reset switch 2 and protection switch 1 are pressed at the same time, a memory erase signal is output through 15 AND circuits. Ru.

By the operation of this circuit, three functions can be realized with two switches, and the number of switches can be reduced.

(Effect of the invention) As explained above, in the present invention, two switches can have three functions, so the number of switches can be reduced to one.
In addition to solving the problem of component mounting by reducing the number of
It has the advantage of being easy to operate because functions can be expressed through operations.
