【発明の詳細な説明】 〈分 野〉 本発明は通信装置、特に通信時間を計測する通信装置
に関する。DETAILED DESCRIPTION OF THE INVENTION <Field> The present invention relates to a communication device, and more particularly to a communication device for measuring communication time.
〈従来技術〉 従来、フアクシミリの通信時間を計測し、これから料
金計算して表示したり記録紙にプリントアウトする等の
機能を持ったフアクシミリ装置があった。この様な装置
では正確な料金を知る為には回線捕捉時間を正確に計測
することが必要である。<Prior Art> Conventionally, there has been a facsimile apparatus having a function of measuring a communication time of a facsimile, calculating a charge from the communication time, displaying the calculated charge, and printing it out on a recording sheet. In such a device, it is necessary to accurately measure the line capture time in order to know the exact charge.
しかし従来の装置はフアクシミリ装置が回線を捕捉し
ている時間のみを計測するものが一般的で、この様な装

回線は電話器によって捕捉されたままであり、課金は続
行されているにもかかわらず通信終了までの時間から料
金を算出していた。従って実際の回線使用料金とフアク
シミリ装置の表示する料金が一値しないという問題があ
った。However, conventional devices generally measure only the time during which the facsimile device is seizing the line, and in such a device, the user turns off the telephone connected to the facsimile at the end of communication. In such a case, the facsimile machine switches the line from the modem side to the telephone side, but the line remains seized by the telephone, and the charge is calculated from the time until the end of the communication even though the charging is continued. Therefore, there has been a problem that the actual line usage fee and the fee displayed by the facsimile apparatus are inconsequential.
そこで回線が捕捉されているか否かの検出器を設け、
通信終了時にオフフツク状態であれば時間計測を続行
し、回線が解放された時点で時間と料金を計算・表示す
る構成が考えられた。So we set up a detector to see if the line was captured,
If an off-hook state is established at the end of communication, time measurement is continued, and a time and charge are calculated and displayed when the line is released.
しかしこの構成だと通信終了後に電話器がオフフツク
状態で回線が捕捉されている時に単に時間計測の為だけ
に制御部は動作しており、無駄な電力を消費していた。However, with this configuration, when the telephone is off-hook after the end of communication and the line is seized, the control unit operates only for time measurement and consumes wasteful power.
また上記構成でも電話器がオンフツクされた時点で制
御部がビジー状態の時、例えばコピー中などの場合には
ビジー状態が解除された後に回線開放を検知する為に正
確な回線捕捉時間を計測することができなかった。Also in the above configuration, when the telephone is turned on, the control unit is in a busy state. For example, in the case of copying, etc., when the busy state is released, an accurate line capture time is measured in order to detect the line release. I couldn't do that.
〈発明の目的〉 本発明は従来例の欠点を除去し、正確な回線捕捉時間
を計測することが可能な通信装置の提供を目的としてい
る。<Object of the Invention> An object of the present invention is to eliminate the drawbacks of the conventional example and to provide a communication device capable of accurately measuring a line capture time.

機に対してアウトパルス方式の選択信号を出力できる。A line is connected between L1 and L2, and a telephone is connected between T1 and T2. When communication is not being performed, the contact cml is on the T1 or T2 side. At this time, if the telephone is off-hook and the line is seized, current flows through one of the photocouplers PC1 and PC2 depending on the direction of the current. Becomes L level. This allows the facsimile apparatus to detect whether or not the line has been seized by the telephone. During communication, the contact cml is switched to the modem side, and when the contact p is kept ON, a direct current flows through the coil RET to capture the line. At this time, the voice band signal is transmitted to the modem 2 (FIG. 1) via the capacitor C and the transformer T.
Alternatively, the voice band signal from the modem 2 is output to the line through the transformer T and the capacitor C. During communication or when the line is seized by the telephone, a DC current flows through one of the photocouplers PC1 and PC2, and either POLARITY0 or POLARITY1 goes to the L level. This allows the fax machine to detect the line polarity. By connecting and disconnecting the contact p while the contact cml is connected to the modem side, an out-pulse selection signal can be output to the exchange.

これ以後回線が開放されたかどうかの監視を行うために
回線開放監視フラグをセツトする次にS1へ戻り、S1,S2,
S7S3のループを繰り返す。First, in the standby state, the main power supply 7 is off, so that the main control unit 3 is not operating. The sub-control unit 6 goes around the loop of S1, S2, S3. When the user sets a document on the facsimile apparatus and presses the one-touch transmission key DK, the sub-controller 6
Detects this, proceeds from S1 to S4, and because the main power supply 7 is OFF, proceeds to S5 and turns on the main power supply 7. When the main power supply 7 is turned on, the main control section 3 starts operation, receives a key code indicating the one-touch transmission key DK from the sub control section 6 in S31 of FIG. 5, and proceeds to S36. At this time, the sub control unit 6 determines in S6 that the main control unit 3
When the key code of the one touch transmission key DK is taught, the process proceeds to S2 and repeats the previous loop of S1 to S3. Main control unit 3 is S36
When the key code is analyzed and it is found that the key is the one touch transmission key DK, the process proceeds to S39. Here, the destination telephone number corresponding to the one-touch transmission key DK is retrieved from the nonvolatile memory 10 and S40.
Then, the contact cml is switched from the telephone TL to the modem, and the pulse relay contact P is turned ON / OFF to output an out-pulse type selection signal to the line. Or DTMF (Dual Tone Mu
lti Frequency) method to send out (call) the line. Next, POLARITY0 and POLARITY1 are monitored in S41, and when the polarity is reversed, the process proceeds to S42, and a line release monitoring command is issued to the sub control unit in S42. At this time, upon receiving the command from the main control unit 3, the sub control unit 6 proceeds from S3 to S12, and since it is neither a line release time request, a current time request nor a display request command,
The process proceeds from S12 to S14, S16, and S18, and proceeds from S18 to S19. Here, the line release monitoring flag is set to monitor whether or not the line has been released thereafter. Then, the process returns to S1, and S1, S2,
Repeat the loop of S7S3.

線をモデム側から電話器TL側へ戻す。Next, the main controller 3 issues a current time request command to the sub controller 6 in S43. Upon receiving this, the sub control unit 6 proceeds from S3 to S12, S14.
Since the current time request command is issued, the process proceeds to S15 and when the time is read from the clock, this time data is passed to the main control unit 3. Then, the process returns to the loop of S1, S2, S7, and S3 again. Upon receiving this time data, the main controller 3 stores this data in the line capture time memory in the nonvolatile memory 10 in S44. And S4
The document is transmitted in step 5, the relay contact cml is turned off in step S46, and the line is returned from the modem to the telephone TL.
次にS33へ進むのであるがこれ以後の動作を2つの場
合に分けて説明する。Next, the process proceeds to S33. The subsequent operation will be described in two cases.
(A)送信終了時に電話器がオンフツクである場合 (B)送信終了時に電話器がオフフツクである場合 (Aの場合) 送信終了時に電話器がオンフツクであるとS46で接点c
mlを電話器TL側に切り換えた時点で回線開放される。(A) When the phone is on hook at the end of transmission (B) When the phone is off hook at the end of transmission (A) If the phone is on hook at the end of transmission, contact c in S46
The line is released when ml is switched to the telephone TL.
この時副制御部6はS1,S2,S7,S3のループを繰り返し

あるのでS3へ進む。これ以後は回線開放監視は行わない
のでS1,S2,S3のループを繰り返す。At this time, if the sub-control unit 6 repeats the loop of S1, S2, S7, and S3, the line is released, and the process proceeds from S7 to S8. Then, a line release flag for notifying the main controller 3 of the line release is set, and a line release monitoring flag is reset so that the line release monitoring is not performed thereafter. Next, in S9, the time is read from the clock, and the time data is stored in the open time memory in the sub control unit 6. Next, since the main power supply 7 is in the ON state in S10, the process proceeds to S3. Thereafter, since the line release monitoring is not performed, the loop of S1, S2, and S3 is repeated.

制御部6の回線開放フラグがセツトされているか否かを
調べこの場合は上述した様にセツトされているのでS47
へ進む。次にS48で副制御部6に回線開放時刻要求命令
を出す。After switching the contact cml in S46, the main control unit 3 checks in S33 whether the line release flag of the sub-control unit 6 has been set. In this case, since the line release flag has been set as described above, the flow proceeds to S47.
Proceed to. Next, in S48, a line release time request command is issued to the sub control unit 6.
副制御部6はこの命令を受けるとS3,S12,S13へ進み、
開放時刻メモリから回線開放時刻を取り出して主制御部
3に渡す。そしてS1,S2,S3のループに戻る。Upon receiving this command, the sub control unit 6 proceeds to S3, S12, S13,
The line release time is retrieved from the release time memory and passed to the main control unit 3. Then, the process returns to the loop of S1, S2, and S3.
主制御部3はS47で開放時刻を副制御部6から受け取

で副制御部に回線開放フラグのクリア命令を出す。次に
S53で副制御部の回線開放フラグはS53でリセツトされて
いるのでC34へ進みS34で副制御部に待機命令を出す。When the main control unit 3 receives the release time from the sub-control unit 6 in S47, it reads out the line capture time stored in S44 from the non-volatile memory 10 in S48 and obtains the difference between these two times in S49 to solve the line capture problem. Ask. Next, in S50, the telephone line usage fee (charge) is calculated from the line capture time, and in S51, the capture time,
Create data to be passed to the sub control unit to display the charge, and
In step 2, this data is sent to the sub-control unit for display. Then S53
Issues a clear command of the line release flag to the sub control unit. next
In S53, since the line release flag of the sub-control unit has been reset in S53, the flow advances to C34 to issue a standby command to the sub-control unit in S34.
副制御部は待機命令を受けるとS3からS12,S14,S16,S1
8,S20と進み、S21で主電源7をOFFしてS1,S2,S3のルー
プへ戻る。Upon receiving the standby command, the sub-control unit proceeds from S3 to S12, S14, S16, S1.
Proceeding to 8, S20, the main power supply 7 is turned off at S21, and the process returns to the loop of S1, S2, S3.
以上の様に送信終了時に電話器をオンフツクしていた
場合は送信動作終了直後に捕捉時間、料金が表示され
る。As described above, when the telephone is on-hook at the end of the transmission, the capture time and the charge are displayed immediately after the end of the transmission operation.
(Bの場合) 送信終了時に電話器TLがオフフツクであると、S46で
接点cmlを電話器TL側に切り換えた時点では回線は捕捉

通話モードへ進む。(In the case of B) If the telephone TL is off-hook at the end of transmission, the line is still held when the contact cml is switched to the telephone TL in S46. Therefore, the operation proceeds from the facsimile communication mode to the communication mode.
従ってS33では副制御部6の回線開放フラグはセツト
されておらず、S32に進み副制御部6に待機命令を出しS
35で主電源7がOFFされるのを待つ。Accordingly, in S33, the line release flag of the sub-control unit 6 is not set, and the process proceeds to S32, where a standby command is issued to the sub-control unit 6, and
Wait for the main power supply 7 to be turned off at 35.
副制御部6はS1,S2,S7,S3のループを繰り返している

開放時刻メモリにストアしS10で主電源7がOFFであるの
でS11で主電源7をONし、これ以後S3,S1,S2のループを
繰り返す。The sub-control unit 6 repeats the loop of S1, S2, S7, S3, but upon receiving a standby command, proceeds to S3, S12, S14, S16, S18, S20.
In S21, the main power supply 7 is turned off. Thereafter, the loop of S1, S2, S7, S3 is continued, and when the user turns on the telephone TL, the process proceeds from S7 to S8. Here, the line release flag is set, the line release monitoring flag is reset, and thereafter the line is not monitored. Next, the time is read from the clock at S9 and stored in the open time memory, and the main power supply 7 is turned off at S10, so that the main power supply 7 is turned on at S11 and thereafter, the loop of S3, S1 and S2 is repeated.

を得ることができる。When the main power supply 7 is turned on, the main controller 3 proceeds to S31, and proceeds to S32 because there is no key code. Since the line release flag of the sub-control unit is set, the process proceeds from S32 to S47, and in the same manner as in the case A, the acquisition time (the facsimile acquisition time + the time when the user has been off-hook) and the fee are displayed, and the operation waits. Return. In other words, even if the terminal is off-hook at the end of transmission, it is possible to obtain the correct line capture time and fee up to that point when the terminal is turned on-hook.

前の例と同様にS7からS8,S9,S10と進みS1,S2,S3のルー
プを繰り返す。The main control unit 3 receives the key code of the function key from the sub control unit in S31, and proceeds to S36 and S37. Since the key code is not a one-touch key key, the process proceeds to S38. If the user turns on the hook while performing the registration operation in S38, the sub control unit 6 proceeds from S7 to S8, S9, S10 and repeats the loop of S1, S2, S3 as in the previous example.
主制御部3はS38の登録動作が終了すると、S33へ行
