DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a call charge display device according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram of essential parts of an embodiment of a call charge display device according to the present invention. In the figure, reference numeral 1 denotes a dial signal detection unit that detects a number input by a dial operation. The reference numeral 2 designates a judging section, which is preset based on the dial number from the dial signal detecting section 1, that is, a local call, a long-distance call using the NTT telephone line, or a city line using the telephone line of the NCC telephone company. Determine the applicable category from the outside call. Reference numeral 3 denotes a storage unit, which is a unit time for an NTT local call (for example, 3 minutes)
, The unit time call charge for each long-distance call area by NTT, and the unit time call charge for each long-distance call area of each NCC company are stored. A setting unit 4 reads and sets a call charge of a call area corresponding to the dial number from the dial signal detection unit 1 from the data read from the storage unit 3 based on the signal from the determination unit 2. A display unit 5 displays a call charge per unit time based on the data set by the setting unit 4. A control unit 6 controls each unit of the apparatus.

Next, the operation of the telephone device with a call charge display according to the present invention will be described with reference to the flowchart of FIG. The dial signal detection unit 1 detects a dial number input by a dial operation (step 1, hereinafter abbreviated as ST1). The number detected by the dial signal detection unit 1 is input to the determination unit 2 via the control unit 6, and first, it is determined whether the beginning of the dial number is "0" or something other than "0". In the case of (ST2: No), it is determined to be a local call (ST3). Based on this determination, for example, the local call charge data for a unit time (for example, 3 minutes) is read from the storage unit 3 via the control unit 6, and is set in the buffer memory or the like by the setting unit 4 (ST4). The display unit 5 displays "city, 3 minutes 10 yen", etc. (ST5).

When the dial number detected by the dial signal detector 1 is a number starting with "0" (ST2: Yes
), By the determination unit 2 via the control unit 6, for example, the top 4
If it is the NCC's telephone company number based on the digit number, etc., and if it is the NCC number (ST6: Yes), N
It is judged that the call is via the CC telephone line (ST7), and the control unit 6
