Description

[Technical Field]

[0001] The present invention relates to a receiver that receives, on a line-by-line basis, fire signals from fire detectors and transmitters connected to lines drawn into a security zone and issues an alarm. [Background technology]

[0002] Conventionally, in the case of P-type (Proprietary-type) receivers installed in automatic fire alarm systems, fire detectors and transmitters are connected to the lines drawn from the receiver to monitor fires on a line-by-line basis, and in the event of a fire, an alarm is issued to building personnel such as the caretaker using sound and indicator lights.

[0003] When an alarm is issued due to a fire, the manager will follow the predetermined handling procedures and perform a series of switch operations and take action in accordance with the following steps: shutting off the main sound system, checking the scene, notifying the fire department, initial fire extinguishing, and guiding evacuation.

[0004] In addition, to ensure that they are able to respond appropriately in the event of a fire, they practice operating the receiver while looking at its instruction manual.

[0005] However, with such conventional P-type receivers, it is conceivable that the administrator may become flustered by the alarm in the event of a fire and be unable to operate the receiver properly.

[0006] To solve this problem, a receiver has been proposed that, in the event of a fire, when a fire signal is received from a fire detector and the main sound is sounded, operating the sound stop switch will activate the voice guidance process, and pressing the voice guide switch will provide voice guidance on the appropriate operating method for the situation (Patent Document 1).Even a manager who is unfamiliar with operating the receiver can operate it according to the voice guidance and perform appropriate operations in an emergency.

[0007] Fig. 8 is an explanatory diagram showing a conventional P-type receiver that uses voice guidance to inform users of how to operate it. As shown in Fig. 8, door panel 111 of P-type receiver 100 has, from the top, a display unit 112 and an operation unit 114, and the lower half of operation unit 114 has a small door 116 that can be opened and closed freely.

[0008] As shown on the right side of the operation unit 114, a fire decision switch 124 is provided in the approximate center, and to the right of that are a sound stop switch 126 and a district sound pause switch 128. A voice guidance switch 120 is provided to the left of the fire decision switch 124, and a voice guidance guide light 122 is provided nearby to the left of that. A recovery switch 130 is also provided inside a small door 116 provided below the operation unit 114.

[0009] In the conventional P-type receiver 100, when a fire signal is received and a main sound alarm is issued from the speaker 118, the sound stop guide light 125 flashes, and when the sound stop switch 126 is pressed, the main sound stops and at the same time the voice guidance guide light 122 flashes, and when the voice guidance switch 120 is pressed in this state, the receiver is enabled to output voice guidance indicating how to operate the device according to the situation at that time.

[0010] The voice guidance output by operating the voice guidance switch 120 includes instructions to operate the fire determination switch 124, the area sound pause switch 128, and the recovery switch 130. To enable the administrator to easily operate the switches in response to the instructions in this voice guidance, the fire determination switch 124, the sound stop switch 126, the area sound pause switch 128, and the recovery switch 130 are labeled with their switch names, and the sound stop switch 126, the area sound pause switch 128, and the recovery switch 130 are labeled with switch numbers 126a, 128a, and 130a, respectively, with "1," "2," and "3" displayed near them.

[0011] Furthermore, a band-like guidance line 132 is drawn in the area where the sound stop switch 126 and the area sound pause switch 128 are arranged in the order of operation. The guidance line 132 starts at the sound stop switch 126, passes through the area sound pause switch 128 on the right, continues further to the right, and bends downward, with an arrow at its tip. The leading part of this arrow displays "Open the door and go to 3" as a message to encourage operation of the recovery switch 130.

[0012] By displaying the arrows of this guidance line 132 pointing toward the sound stop switch 126, the area sound pause switch 128, and further toward the recovery switch 130 inside the small door 116, the order in which to operate the switches indicated by the voice guidance when the voice guidance switch 120 is pressed can be visually understood. [Prior art documents] [Patent documents]

[0013] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-087111 [Patent Document 2] Japanese Patent Application Publication No. 6-176289 [Patent Document 3] Japanese Patent Application Laid-Open No. 2002-109651 [Patent Document 4] Japanese Patent Application Laid-Open No. 2007-286842 [Patent Document 5] Japanese Patent Application Publication No. 8-235462 Summary of the Invention [Problem to be solved by the invention]

[0014] In the case of a receiver that uses voice guidance to inform the operator of the operation method when such a fire signal is received, when a fire signal is received by the receiver 100, the manager can stop the main sound by operating the No. 1 sound stop switch 124 after seeing the flashing sound stop guide light 125 without listening to the voice guidance, and then proceed to check the site.

[0015] If an on-site check confirms that there is no fire, the administrator operates the area sound pause switch 128 No. 2 located on the guidance line 132, and finally opens the small door 116 and operates the recovery switch 130. However, since this is not an emergency, even an administrator who is unfamiliar with operating receivers can perform the appropriate operations by looking at the arrows on the guidance line 132 and the numbers on each switch.

[0016] On the other hand, if a fire is confirmed during an on-site inspection, it is necessary to operate the fire determination switch 124. However, in the event of an emergency such as a fire, if a manager is unfamiliar with operating the receiver and does not operate the voice guidance switch 120 and listen to the voice guidance, because the area sound pause switch 128 No. 2 is located next to the sound stop switch 126 No. 1 that was operated first, the manager may intuitively mistakenly believe that the switch to operate after No. 1 is the area sound pause switch 128 No. 2, and may operate it incorrectly, which could cause the manager to have difficulty operating the fire determination switch 124.

[0017] Furthermore, after operating the fire decision switch 124, it is necessary to notify the fire department, carry out initial fire extinguishing, and provide evacuation guidance. However, if the voice guidance is not heard, there is a possibility that these steps will not be taken promptly and appropriately.

[0018] This type of problem may also occur in a receiver that does not have a voice guidance function but has the same switch arrangement of the operation unit 114.

[0019] To provide a receiver that enables an operator to intuitively grasp the operating procedure when a fire signal is received through a guidance line without relying on voice guidance, and enables even an inexperienced operator to operate and respond appropriately and quickly. [Means for solving the problem]

[0020] (Receiver with voice guidance function) The present invention is a receiver provided with a guidance line that guides the operation when a fire signal is received from a line drawn into a warning area and a main sound is sounded, The guidance line is A first guidance line is drawn from the sound stop switch that stops the main sound and has a predetermined switch arranged thereon for performing operations necessary for dealing with the situation after operating the sound stop switch; a second guidance line that is drawn out from the sound stop switch separately from the first guidance line and has a voice guidance switch disposed thereon that outputs voice guidance; Equipped with The first guidance line is After extending in a predetermined direction from the acoustic kill switch, A fire detection switch is installed to be operated when a fire is confirmed during on-site inspection. , and fire confirmation extending in the specified direction Guidance lines and a district sound pause switch to temporarily stop district sound but Placed , and non-fire confirmation extending in the same direction. Guidance Line A recovery switch is located at the end of the guidance line drawn from the district acoustic pause switch, which receives a fire signal and returns the activated receiver state to the monitoring state. The second guidance line is pulled out from the acoustic kill switch in a direction different from the predetermined direction in which the first guidance line is pulled out. It is characterized by: [Effects of the Invention]

[0023] (Effect of receiver with voice guidance function) The present invention provides a receiver equipped with guidance lines that guide users in the operation of a receiver when a fire signal is received from a line extended into a restricted area and a main sound is sounded. The guidance lines include a first guidance line extending from an audio stop switch that stops the main sound and on which are located predetermined switches for performing operations necessary for responding to the response after operating the audio stop switch, and a second guidance line that is separately extended from the audio stop switch and on which are located audio guide switches for outputting audio guidance. Therefore, it is intuitively clear that the audio stop switch located at the beginning of the first guidance line, which is the operation starting point, is the first switch to operate when a fire signal is received and the main sound is sounded. Even a manager who is unfamiliar with operations can operate the audio stop switch to stop the main sound without hesitation when a fire signal is received. Furthermore, it is intuitively clear that appropriate responses can be taken by operating the switches on the first guidance line following the operation of the audio stop switch.

[0024] In addition, by operating the voice guidance switch located on the second guidance line, which is separate from the first guidance line, voice guidance is activated, and the guidance content on the appropriate operating method according to the situation is announced by voice.Since the content of the voice guidance is consistent with the arrangement order of each switch on the first guidance line, the cooperation of the two enables even administrators who are unfamiliar with operating receivers to operate them appropriately and take appropriate measures by following the voice guidance and the first guidance line.

[Figure 8] An explanatory diagram showing the appearance of a conventional receiver and an enlarged view of the operation panel DETAILED DESCRIPTION OF THE INVENTION

[0026] [Receiver configuration] Figure 1 is a block diagram showing the functional configuration of a receiver according to the present invention installed in a P-type fire alarm system. As shown in Figure 1, P-type receiver 10 is installed in a manager's room or the like, and a sensor line 12 is drawn from P-type receiver 10 to the security area of ​​the building.

[0027] A fire detector 14 and a transmitter 15 are connected to the detector circuit 12. Various on-off type detectors are used as the fire detector 14, such as a photoelectric spot detector, a differential spot detector, and a constant temperature spot detector. A control circuit 16 is also drawn from the P-type receiver 10, to which a fire door 18 and a damper 19 are connected as smoke control devices.

[0028] The P-type receiver 10 is equipped with an MPU (microprocessor) 20, which is composed of a computer circuit equipped with a CPU, memory, and various input / output ports. The MPU 20 is equipped with a line receiving unit 22, a line control unit 24, a display unit 25, an operation unit 26, an alarm unit 27, and a report transfer unit 28.

[0029] The line receiving unit 22 detects the alarm current that flows when the fire detector 14 detects a fire or when the transmitter 15 is pressed, and outputs a fire signal to the MPU 20. The fire detector 14 continues to issue an alarm when it detects a fire based on smoke density or temperature, and stops issuing an alarm when the fire condition based on smoke density or temperature is resolved. For this reason, the line receiving unit 22 outputs a fire signal while the fire detector 14 detects a fire and is issuing an alarm, and stops outputting the fire signal when the fire condition is resolved and the fire detector 14 stops issuing the fire alarm.

[0030] The line control unit 24 outputs a control signal to the fire door 18 and the damper 19, thereby releasing the latches of the fire door 18 and the damper 19 and causing them to close.

[0031] The display unit 25 is provided with a district indicator light, a fire representative light, a smoke prevention representative light, etc. The operation unit 26 is provided with an audio stop switch, a fire determination switch, a district audio pause switch, a recovery switch, etc.

[0032] The alarm unit 27 is provided with a speaker, buzzer, etc. that issues audible alarms and voice guidance. The report unit 28 is provided with a report circuit using a relay contact that outputs a representative report signal or a line report signal as a non-voltage signal to an externally connected display panel, for example.

[0033] To realize functions by executing programs, the MPU 20 is provided with a reception control unit 30 and a voice guidance processing unit 32. When a fire signal is received on a line-by-line basis from a fire detector 14 connected to the detector line 12, for example, which is drawn out to the alert area, the reception control unit 30 controls the flashing or lighting of the fire representative light and the area indicator light indicating the area where the fire has occurred, and also controls the activation of the receiver's main sound.

[0034] When the reception control unit 30 detects the reception of a fire signal and determines that the main sound is to be stopped by operating the sound stop switch provided in the operation unit 26, the voice guidance processing unit 32 controls the output of voice guidance indicating the operation method according to the situation from the speaker of the alarm unit 27, each time it determines the operation of a voice guidance switch, which will be explained later and is also provided in the operation unit 26.

[0035] [Receiver operation panel] (Overview of the operation panel) FIG. 2 is an explanatory diagram showing the appearance of the receiver, and FIG. 3 is an explanatory diagram showing the operation unit of the receiver of FIG. 2 with the small door open.

[0036] As shown in Figure 2, the front surface of the door panel 11 of the P-type receiver 10 has a display unit 25 and an operation unit 26 arranged from the top, and a small door 34 that can be opened and closed freely is provided in the lower half of the operation unit 26, and a speaker is placed inside the acoustic hole 35 at the lower right end of the display unit 25.

[0037] The display unit 25 is provided with a fire warning light, a smoke prevention warning light, and multiple area warning lights, etc. As shown in Fig. 3, the operation unit 26 is provided with an audio stop switch 36, a voice guidance switch 38, a fire determination switch 44, an area audio pause switch 50, a recovery switch 54, and a call microphone switch 56. The recovery switch 54 is located inside the small door 34 that opens downwards when it is closed.

[0038] The sound stop switch 36 is a switch that stops the main sound that sounds when a fire signal is received by the P-type receiver 10. The local sound pause switch 50 is a switch that temporarily stops the local sound that sounds in conjunction with the main sound that sounds when a fire signal is received by the P-type receiver 10.

[0039] The fire determination switch 44 is a switch that, when a fire signal is received, cancels the acoustic alarm stop, alarm transfer stop, interlock stop, etc., switches that have been set to stop. The recovery switch 54 is a switch that returns the receiver state of the P-type receiver 10 that has been activated by receiving a fire signal to the normal monitoring state.

[0040] (Operation panel guidance placement) An audio stop switch 36, which is the first to be operated when a fire signal is received and the main sound is sounded, is located at a predetermined operation starting position on the left side of the operation unit 26. The audio stop switch 36 is an illuminated switch with an audio stop guide light 36a in the center of the operation button, and when a fire signal is received and the main sound is sounded, the audio stop guide light 36a flashes to prompt the operation of the audio stop switch 36.

[0041] A band-shaped guidance line 40a is drawn out to the right from the sound stop switch 36, with the switch name "Stop Sound" displayed close to the sound stop switch 36, and an emergency indicator light 42 is placed following the guidance line 40a. A guidance line 40b continuing from the emergency indicator light 42 displays "Please check the site" as an on-site confirmation message 41 requesting that the administrator check the fire site. When the sound stop switch 36 is operated, the emergency indicator light 42 flashes to indicate the on-site confirmation message 41, urging the administrator to check the fire site.

[0042] The guidance line 40b then branches into a fire confirmation guidance line 40c that displays "In case of fire" when the result of the on-site confirmation is a fire, and a non-fire confirmation guidance line 40e that displays "In case of no fire" when the result of the on-site confirmation is a non-fire.

[0043] A fire decision switch 44 is arranged next to the fire confirmation guidance line 40c, and the switch name "decision" is displayed on guidance line 40d from the fire decision switch 44. An emergency guide lamp 46 is arranged next to guidance line 40d, and fire response information 48 is displayed next to the emergency guide lamp 46. In addition to the characters for calling 119, evacuation guidance, and initial fire extinguishing, the fire response information 48 includes a calling 119 symbol 48a, an evacuation guidance symbol 48b, and an initial fire extinguishing symbol 48c, all of which are specified figures.

[0044] When the fire decision switch 44 is operated, the guidance indicator light 46 flashes to indicate fire response information 48, urging the manager to call 119, provide evacuation guidance, and take initial fire extinguishing measures.

[0045] On the other hand, a district sound pause switch 50 is placed on the non-fire confirmation guidance line 40e, and the switch name "District sound pause" is displayed adjacent to the district sound pause switch 50 on the guidance line 40f extended to the right from there.

[0046] The guidance line 40f drawn from the area sound pause switch 50 bends downward at the right end and heads toward the recovery switch 54 located inside the small door 34, with the recovery switch 54 located at the end of the guidance line 40f.

[0047] An instruction indicator light 52 is placed at the bent portion of the guidance line 40f, and displays the message "Open the door and operate." When the area sound pause switch 50 is operated, the instruction indicator light 52 flashes to prompt the operation of the recovery switch 54.

[0048] In this way, starting from the sound stop switch 36, the system branches off into the fire determination switch 44 side and the area sound pause switch 50 side depending on the results of on-site confirmation, and guidance lines 40a to 40f are displayed from the area sound pause switch 50 toward the recovery switch 54 inside the small door 34. By arranging guidance indicator lights 42, 46, and 52 following each switch, it is possible to intuitively understand the operation and response procedures when a fire signal is received and the main sound is sounded by looking at the operating unit 26, enabling quick and appropriate operation and response.

[0049] (Voice guidance operation switch) A voice guidance switch 38 is disposed below the sound stop switch 36 located at the operation starting point on the left side of the operation unit 26, and voice guidance lights 38a are provided on both sides of the voice guidance switch 38.

[0050] In this embodiment, when a fire signal is received by the P-type receiver 10 and the main sound is sounded from the speaker of the alarm unit 27, the sound stop guide light 36a flashes, and when the sound stop switch 36 is operated, the main sound stops, and at the same time the voice guidance guide light 38a flashes to prompt the operation of the voice guidance switch 38, and when the voice guidance switch 38 is operated in this state, the system becomes able to output voice guidance indicating the operation method according to the situation at that time.

[0051] The guidance output by operating the voice guidance switch 38 includes instructions to operate the fire determination switch 44, the local sound pause switch 50, and the restoration switch 54. To enable the administrator to easily operate the instructions given by this voice guidance, the switch name is displayed near each switch, and the sound stop switch 36, the local sound pause switch 50, and the restoration switch 54 are displayed with the switch numbers "1," "2," and "3" in large, easily visible letters.

[0052] This voice guidance displays guidance lines 40a to 40f leading from the acoustic stop switch 36 on the operating unit 26 to the recovery switch 54 inside the small door 34, and in conjunction with the operation of the guidance indicator lights 42, 46, 52 located next to each switch, it enables appropriate and prompt operation and response when a fire signal is received.

[0053] [Receiver control operation] Fig. 4 is a flowchart showing the control operation of the receiver of Fig. 1. As shown in Fig. 4, the reception control unit 30 of the P-type receiver 10 shown in Fig. 1 checks whether a fire signal has been received in step S1, and upon receiving a fire signal from the fire detector 14 or transmitter 15 on a line-by-line basis, proceeds to step S2, activates the fire representative light, and simultaneously activates the district indicator light corresponding to the line that received the fire signal, and then sounds the main sound in step S3. In this embodiment, the main sound is sounded by audio output, and an audio message that combines a pseudo alarm sound indicating a fire and an alarm message indicating the nature of the fire is output, for example, "'First pseudo sound' Fire. There is a fire. Please check the location."

[0054] Next, the process proceeds to step S4, where it is determined whether the sound stop switch 36 has been operated. If it is determined that the sound stop switch 36 has been operated, the main sound, i.e., the voice message output in step S3, is stopped in step S5. If it is determined that the sound stop switch 36 has not been operated, step S4 is repeated.

[0055] Next, in step S6, the guidance indicator light 42 and the voice guidance light 38a provided on the operation unit 26 are activated, and the on-site confirmation message 41 is displayed to prompt the user to confirm the fire site, and also indicates that there is operation guidance to be output by operating the voice guidance switch 38. Next, in step S7, it is determined whether or not the voice guidance switch 38 has been operated, and if it is determined that the switch has been operated, voice guidance process 1 is performed in step S8.

[0056] If it is determined in step S7 that the voice guidance switch 38 has not been operated, the process proceeds to step S9, where it is determined whether or not the local sound is sounding. If it is determined that the sound is sounding, the process proceeds to step S10, and since the results of on-site inspection indicate that there is a fire, the fire decision switch 44 is operated, if it is determined that the fire decision switch 44 has been operated, the process proceeds to step S11, where a fire decision process is performed to automatically cancel the switch that is set to off at that time. Next, in step S12, the guidance indicator light 46 provided subsequent to the fire decision switch 44 is activated, and the fire response information 48 is displayed as a symbol to prompt the user to call 119, provide evacuation guidance, and take initial fire extinguishing measures.

[0057] Thereafter, in step S13, it is determined whether the voice guidance switch 38 has been operated, and if it is determined that it has been operated, voice guidance process 2 is performed in step S14. If it is determined that the voice guidance switch 38 has not been operated, the process proceeds to step S15, where it is determined whether the recovery switch 54 has been operated. If it is determined that the recovery switch 54 has been operated, the process proceeds to step S32, where line cut control is performed on the detection line 12 that received the fire signal to recover the fire detector 14 that triggered the alarm, and a recovery process is performed to return the receiver to normal monitoring operation. If it is determined that it has not been operated, the process returns to before step S13.

[0058] On the other hand, if the on-site check reveals no fire, the district sound pause switch 50 is operated, so in step S10, if it is determined that the fire determination switch 44 has not been operated, the process proceeds to step S16, and if it is determined that the district sound pause switch 50 has been operated, the process proceeds to step S17, where processing is performed to temporarily suspend the district sound alarm that is sounding. Subsequently, in step S18, the guidance indicator light 52 provided subsequent to the district sound pause switch 50 is activated, prompting the operation of the recovery switch 54. Steps S19 to S21 perform the same processing as steps S13 to S15, except that voice guidance processing 3 is performed in step S20.

[0059] Figure 5 is a flowchart showing the control operation of the receiver after determining that the district sound has been stopped in step S9 of Figure 4. If it is determined in step S9 that the district sound has been stopped, the process proceeds to step 22, and if it is determined that the fire determination switch 44 has been operated, the same process as step 10 is carried out, but if it is determined that the switch has not been operated, the district sound alarm has already been stopped, so the process to suspend is not carried out, and the process proceeds to step S28, where the guidance indicator light 52 provided subsequent to the district sound suspension switch 50 is activated to prompt the operation of the recovery switch 54.

[0060] Steps S23 to S27 are the same as steps S11 to S15 except that step S26 performs voice guidance process 4. Steps 29 to 31 are the same as steps S13 to S15 except that step 30 performs voice guidance process 5.

[0061] (Voice guidance processing) FIG. 6 is a flowchart showing details of the voice guidance processes 1 to 5 in FIGS.

[0062] (Voice guidance processing 1) When the voice guidance processing unit 32 provided in the P-type receiver 10 in FIG. 1 determines that the voice guidance switch 38 has been operated in step S7 in FIG. 4, it proceeds to step S100 in FIG. 6 and outputs voice guidance saying, "The detector has been activated. Please check the situation at the location where the alarm occurred."

[0063] Next, the process proceeds to step S101, where it is checked whether or not the local sound is ringing, and if it is ringing, the process proceeds to step S102, and if it is stopped, the process proceeds to step S202 in Fig. 7. In step S102, where it is determined that the local sound is ringing, the voice guidance "If it is determined that there is a fire, please press the fire determination switch" is output, and after one second of silence, the voice guidance "If it is determined that there is no fire, please press the local sound pause switch No. 2" is output in step S103.

[0064] If the on-site check reveals that there is a fire, the fire determination switch 44 is pressed in accordance with the instructions of the voice guidance in step S102, and if it is determined in step S104 that the fire determination switch 44 has been operated, the switch that is currently set to stop is automatically released, and in step S105, as the fire determination process is completed, the voice guidance is output saying, "Fire determination process has been completed."

[0065] Subsequently, if it is determined in step S106 that the voice guidance switch 48 has been operated, the voice guidance output in step S107 is "Please call 119. Depending on the situation, please carry out initial fire extinguishing or evacuation guidance." After it is determined in step S106 that the voice guidance switch 48 has not been operated, or if it is determined in step S108 after the processing of step S107 that the recovery switch has been operated, the voice guidance ends in step S115. If it is determined in step S108 that no operation has been performed, the process returns to before step S106.

[0066] Furthermore, after determining in step S104 that there is no fire based on the results of the on-site inspection and that the fire determination switch 44 has not been operated, the district sound pause switch 50 is operated in accordance with the voice guidance in step S103, and if it is determined in step S109 that the district sound pause switch 50 has been operated, the district sound is paused and the voice guidance "District sound has been paused" is output in step S110.

[0067] Next, if it is determined in step S111 that the voice guidance switch 48 has been operated, the voice guidance "Please press the recovery switch No. 3" is output in step S112, and the processing in step S113 is the same as that in step S108 except that if it is determined that no operation has been performed, the processing returns to before step S111.

[0068] After determining in step S109 that the area sound pause switch 50 has not been operated, if it is determined in step S114 that the voice guidance switch 48 has been operated, the process returns to before step S102 and voice guidance is provided again, and if it is determined that no operation has been performed, the process returns to before step S104.

[0069] On the other hand, if it is determined in step S101 that the local sound system is stopped and the process proceeds to step S202 in Figure 7, the voice guidance will output, "If it is determined that there is a fire, please press the fire determination switch.", followed by one second of silence and then in step S203, the voice guidance will output, "If it is determined that there is no fire, please press the recovery switch No. 3."

[0070] If the on-site check reveals a fire and it is determined in step S204 that the fire determination switch 44 has been operated, the processing of steps S205 to S208 is the same as that of S105 to S108, except that the destination step on the flowchart is different.

[0071] Furthermore, if the results of the on-site check indicate that there is no fire and it is determined in step S204 that the fire determination switch 44 has not been operated, the area sound system has already been stopped, so no voice guidance to pause is given, and if it is determined in step S209 that the recovery switch has been operated, the voice guidance ends in step S115.

[0072] The processing in step S210 is the same as that in step S114, except for the destination step in the flowchart. Once it has been determined that the voice guidance switch 48 has been operated in any step, appropriate voice guidance may be automatically repeated without determining again whether the voice guidance switch 48 has been operated. Also, appropriate voice guidance may be automatically processed even if the voice guidance switch is not operated.

[0073] The voice guidance processing when the transmitter is activated differs only in that the voice guidance in step S100 of Figure 6 changes from "The detector has been activated" to "The transmitter has been pressed." The other processing and voice guidance are the same as when the detector is activated.

[0074] (Voice guidance processing 2 to 5) The voice guidance process 2 starts before step S107, and the subsequent steps follow the voice guidance process 1.

[0075] The voice guidance process 3 starts before step S112, and the subsequent steps follow the voice guidance process 1.

[0076] The voice guidance process 4 starts before step S207, and the subsequent steps follow the voice guidance process 1.

[0077] The voice guidance process 5 starts before step S209, and the subsequent steps follow the voice guidance process 1.

[0078] [Receivers without voice guidance function] Another embodiment of the receiver according to the present invention may be a receiver that does not have a voice guidance function. A receiver that does not have a voice guidance function may be configured by removing the voice guidance processing unit 32 from the MPU 20 in Fig. 1, and removing the voice guidance switch 38 and the voice guidance guide light 38a provided on the operation unit 26 in Fig. 3, and further removing the operation determination of the voice guidance switch and the voice guidance processing in Figs. 4 and 5 from the receiver control.

[0079] [Modifications of the present invention] The above embodiment has been described with reference to a P-type receiver as an example, but the present invention can also be applied to any receiver that does not have a display for displaying images as an operation and display unit of the receiver.

[0080] Furthermore, the present invention is not limited to the above-described embodiment, but includes appropriate modifications that do not impair the objects and advantages thereof, and is not limited by the numerical values ​​shown in the above-described embodiment. [Explanation of symbols]
