Abstract

PURPOSE:To restrict dialing depending on a class of a memory card in use by storing a dial number onto a memory card freely loaded/unloaded to/from a telephone set and providing a dialing means using a display means so as to retrieve an object telephone number from the memory card and making dialing. CONSTITUTION:In the case of dialing, a memory card is loaded from a memory card loading slot and loaded to a card loading section 11. When a dialing number retrieval button in an input section 17 is depressed according to the guidance of a predetermined operation displayed on a display section 18, a card read section 16 reads a telephone number corresponding to the predetermined depression button is read from the card memory under the control of a CPU 20 and displayed on the display section 18. Then one of telephone numbers displayed on the display section 18 is selected by a dial button in the input section 17 and a speaker button in the input section 17, the CPU 20 sends a signal to close a telephone line to a line control section 12. Thus, dialing is restricted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone set, and particularly to a telephone set subject to outgoing call restrictions.

[Conventional technology]

Conventionally, this type of telephone has an internal call restriction setting section that sets a call restriction class, and when a telephone number set in the call restriction setting section is detected during dial input, for example, a long-distance signal number is detected. In some cases, the system was configured not to dial out calls.

[Problem to be solved by the invention]

The above-mentioned conventional telephone has an internal call restriction setting section that sets a call restriction class, and is configured to not dial if the calling number set in the call restriction setting section is detected during dial input. , Since the presence or absence of call restriction and the call restriction class are determined for each telephone, regardless of who is using the phone, dialing cannot be made due to restrictions on the presence or absence of call restriction and the call restriction class of that phone. There is a drawback.

[Means to solve the problem]

The telephone of the present invention includes a memory card storing a plurality of preset telephone numbers, a card attachment detection means for detecting attachment of the memory card, and a card attachment detection means for detecting attachment of the memory card. a reading means for reading the telephone number from the memory card; a display means for displaying the telephone number read by the reading means; a selection means for selecting one of the telephone numbers displayed on the display means; and a selection means for selecting one of the telephone numbers displayed on the display means. and dialing means for converting the selected telephone number into a dialing signal and transmitting it to the line.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIGS. 1 and 2 are a top view and a block diagram showing an embodiment of the present invention, respectively, and FIG. 3 is a diagram showing an example of a memory card used in this embodiment.

1 and 2, the telephone 1 of this embodiment has a card mounting portion 11 of the memory card 3 shown in FIG. a card reading section 16 for reading the telephone number, a storage section 19 for storing the read telephone number, a display section 18 for displaying the read telephone number, a telephone number call button 2241, a call number search button 25. an input section 17 including a speaker button 26, etc.; a dial transmission section 13 that converts a telephone number into a dial signal and sends it to the telephone line;
A line control unit 12 that controls the line closure transistor 159 and line closure control transistor 14 to open and close the DC loop of the telephone line, and a central control unit (hereinafter referred to as CPU) that controls the entire telephone 1. 20.

Next, the operation of this embodiment will be explained using FIG. 1, FIG. 2, and FIG. 3.

It is assumed that a plurality of telephone numbers are stored in advance in the memory card 3 shown in FIG.

First, when making a dial call, the memory card 3 is inserted through the memory card insertion hole 27 and attached to the card attachment section 11.

Next, follow the predetermined operational guidance displayed on the display section 18 and press the calling number search button 25 in the input section 17.
When you press , the card reading section 1 is activated under the control of the CPU 20.
6 reads the telephone number corresponding to the predetermined push button from the card memory 3 and displays it on the display section 8.

Next, when one of the telephone numbers displayed on the display section 18 is selected using the call button 24 within the input section 7 and the speaker button 26 within the input section 17 is pressed, the CPU 20 causes the line control section 12 to make a telephone call. Sends a signal to close the line.

The line control section 12 receives this signal and turns on the line closing control transistor 14, thereby turning on the line closing transistor 15 and forming a DC loop of the telephone line.

Next, when the CPU 20 detects a dial tone from the telephone line, it sends the selected telephone number to the dial transmitter 13, and the dial transmitter 13 converts the received telephone number into a dial signal and transmits it to the telephone line.

In this embodiment, it is possible to make a dial call using only the telephone number stored in advance in the memory card being used. That is, dialing is restricted depending on the memory card used.

〔Effect of the invention〕

As explained above, the present invention has a dialing means that stores a calling number in advance in a memory card that is detachable from a telephone, searches for a target telephone number from this memory card using a display means, and dials the number. This allows each phone user to carry a memory card, and only the specific user carrying the memory card can dial only the calling number registered on the memory card.
This has the effect that dialing can be restricted depending on the memory card used.
