Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voice recording and reproducing device, in particular for message transmission, which is equipped with an object detector.

[Conventional technology]

Conventionally, there have been recording and reproducing devices that use endless magnetic tape or audio ICs to transmit messages to a specific person or an unspecified number of people, but most of these devices start the playback operation manually. If the playback operation is not performed, the message will not be played back, so even if you want to send a message to a specific person, the message may not be sent. Some devices are combined with a timer so that playback starts at a set time, but if there is no one to send the message to at that time, the message delivery function will not work. To this end, it has been proposed to include an object detector so that the playback operation is started when the object detector detects a person. In this case, the regeneration operation will start when someone approaches, so if it is used to transmit messages at home, the regeneration operation will start when someone returns home, which is very preferable. It has become a thing.

[Problem M that the invention attempts to solve]

However, if an object is detected by the object detector, the playback operation will start no matter what the object is.
It is not possible to convey a message only to a specific person. Another problem is that the content to be reproduced is always the same unless the recorded content is replaced, and it is not possible to switch and reproduce more than one content. The present invention has been made in view of these points, and its purpose is to provide a voice recording and reproducing device with an object detector that can transmit messages to a specific person;
To provide a voice recording and reproducing device with an object detector capable of switching and reproducing a plurality of contents.

[Means to solve the problem]

Accordingly, the present invention provides a voice recording and reproducing apparatus equipped with an object detector, and a first aspect of the present invention is that the apparatus includes a manual reproduction start means and a notifying means for making a notification based on the output from the object detector. The second feature is that it has a plurality of recorded contents and a switching means for switching the contents to be reproduced based on the output from the object detector. [Function] According to the former of the present invention, the object detector activates the notification means to prompt manual playback operation, and according to the latter, the recorded content to be played back is automatically controlled by the output from the object detector. Can be switched. [Embodiment] The present invention will be described below in detail based on the illustrated embodiment. This recording/playback device uses a cassette-type endless magnetic tape (not shown) having a recording/playback time of about 30 seconds as a recording medium.

A recording/reproducing head 42 for magnetic tape is connected to the common contact point b. A recording amplifier 43 and a microphone 44, and a reproduction amplifier 45 and a speaker 46 are connected to the two switching contacts in the switching contact section 6b, respectively. Note that the playback amplifier 45 is normally used as the recording/playback head 4.
Reference numeral 10 in FIG. 2 is a power supply section, which is connected to the power source 2 and the erasing head 41 is disconnected. However, if someone approaches this recording/playback device, the object detector 2 detects this and the monostable multivibrator 2
1 to activate a buzzer 22 to notify those who approach that a message to be transmitted is stored. When the regeneration switch 30 is operated in response to this notification, the transistor 33 is turned on and the motor 3 is turned on in order to input a bi-level signal to the set terminal S of the flip-flop 32.
5 and lights up the tape running indicator lamp 36, and the contents recorded on the magnetic tape are reproduced. Then, when the endless magnetic tape goes around and returns to its original state, the tape end detection sensor 4
The motor 35 is turned off at the output of . Therefore, the next playback operation is always performed from the beginning of the magnetic tape. To record onto magnetic tape, switch the recording switch 6 and use the microphone 4.
This is done through 4. Another embodiment is shown in FIGS. 4 and 5, in which a voice recording/reproducing IC 9 is used as the notification means instead of a buzzer. If you record the name of the person you want to send a message to, for example, the words C, Dad, and J, on this audio recording/playback IC 9, and also record the message you want to send to the magnetic chip 7, the object detector 2 will detect the object. 90 in the figure is a recording switch for voice recording/reproducing ICQ. be. Another embodiment is shown in FIG. 6. Here, the recording/reproducing device is equipped with two erasing heads 41a, 41b and two recording/reproducing heads 42a, 42b, and uses a magnetic tape divided into two tracks. I use what I can.

The number of seconds indicating the elapsed time is written on the surface of this rotary plate 82,
There is a window 80 on the front of the container 1 through which the above-mentioned seconds can be seen. It goes without saying that the rotary plate 82 is marked with an indication corresponding to the time required for the endless magnetic tape to make one revolution. Now, if you press the recording switch 6 to start recording, the rotary plate 82 will also start rotating and display the elapsed time.For this purpose, effective recording can be made using the full recording time of the endless magnetic tape. It can be carried out. As shown in FIGS. 10 and 11, the tape running indicator lamp 36 is connected to the output terminal Q of the flip roller 132 of the motor drive block 3 via the integrating circuit block 83 and the V/F converter 84, and the magnetic tape is The flashing cycle of the tape running indicator lamp 36 may become faster as the running time elapses. As shown in FIGS. 12 and 13, a comparator 85 may be provided in place of the V/F converter 84 so that the lamp 36 is turned on when the magnetic tape is about to end. Furthermore, as shown in FIG. 14, it is also possible to use a recording and reproducing device with a two-track tie 7 and use one of the tracks to display the remaining amount by measuring the elapsed time. That is, a comparator 92 is connected to the output terminal Q of the flip roller 132 of the motor drive block 3 via an overturning circuit 91, and the comparator 92 and the oscillation circuit 93
