Description

[Detailed Description of the Invention] This invention relates to a timer device for an electronic device, and more particularly, to a coupling mechanism between an electronic device and a timer when the operation of the electronic device is controlled by the timer.

Conventionally, the technical means of removably connecting a small tape recorder with an auto-stop mechanism to a radio as an electronic device and operating both simultaneously to record mixing recording or radio reception No. 4 on tape is as follows. It is well known.

In addition, when a tape recorder is connected to a radio, the radio's sleeve switch and the tape recorder's auto-stop mechanism are combined, and the auto-stop mechanism operates when the tape is finished, stopping the tape recorder and at the same time shutting down the radio's power switch. Technological means have already been proposed that automatically turn off the radio and stop the operation of the radio.

According to this technical measure, the tape recorder coupled to the radio also serves as a timer for the radio.

In other words, while the tape recorder is operating and the tape is being fed, the radio is also operating, but when the tape has finished being fed, the power to the radio is also cut off in conjunction with the tape recorder's auto-stop mechanism. This means that the operating time of the radio can be controlled by the tape feeding time.

Therefore, you can make the tape recorder work as a timer.

However, when the tape recorder is removed from the radio and the radio is used as a standalone unit, this function disappears.

In other words, since the tape recorder can be detachably connected to the radio, the two can be freely disconnected from each other, and when the connection is disconnected, the radio functions as a single radio. Furthermore, although the tape recorder performs its own functions as a standalone tape recorder, the interlocking relationship between the two disappears, and the radio becomes an ordinary radio without a timer function.

In addition, if the tape recorder is removed from a radio to which a small tape recorder can be detachably connected, the tape recorder mounting section of the radio becomes an empty space, so the appearance of this radio is very poor. It also has the disadvantage of getting worse.

The purpose of the present invention is to focus on the above-mentioned points, and to attach and detach a small tape recorder to a radio, which is an electronic device, when the tape recorder is not connected to the radio. To provide a timer device for an electronic device, in which a timer formed to have approximately the same size is mounted using an electrical connection terminal of the mounting part, and the operation of the timer is controlled by the timer.

Hereinafter, the present invention will be explained with reference to an illustrated embodiment.

The compact tape recorder used in this example is an ultra-compact tape recorder developed by the applicant that is sized to fit easily in a shirt pocket. A tape recorder is adapted to be removably coupled to a portable radio.

First, the manner in which the radio and the tape recorder are connected will be explained. As shown in FIG. A micro-sized tape recorder 3 is detachably connected thereto.

A dial display window 4 is provided at the upper part of the front surface of the radio 1, and a speaker 5 is provided below the dial display window 4.

Further, on the top surface, there are provided an operation knob 6 for a power switch, a volume adjustment knob 7, a tuning dial knob 8, and the like.

The electric circuit of this radio 1 is constructed as shown in FIG. 2 with its main components.

This configuration is well known, and the signal voltage induced in the antenna 11 is converted into the desired reception signal 4 by a circuit 12 that performs the functions of a tuner, intermediate frequency amplification, and detection, and is then transmitted via a switch S1. The signal is amplified by the audio amplifier 13 and then output from the speaker 5 through the earphone jack 14.

Also, the built-in power supply B1 is used as the drive power source for this radio 1, and the power from this power supply B1 is supplied to each circuit via the external power connection jack 13 and the power switch S2. ing.

The power switch S2 is composed of a changeover switch that interlocks with the switch S1, and can be switched using the operating knob 6 of the power switch. When the radio 1 is used alone, its movable contact Sla , S2a to each fixed terminal S1b, S2b.

Further, when the amplifier 13 of the radio 1 is used to reproduce the tape reproduction output, the movable contact pieces S1a and S2a are switched to the respective fixed terminals 51C9S2C.

In this case, when the switch S3 interlocked with the auto-stop mechanism of the tape recorder 3 is closed, driving power is supplied from the power source B1 to the electric circuits of the radio 1 and the tape recorder 3 through the switch S3.

Of course, in this case as well, when the switch S3 interlocked with the auto-stop mechanism of the tape recorder 3 is closed, the driving power of the power source B1 is supplied to the electric circuits of the radio 1 and the tape recorder 3, respectively.

In this way, when the tape recorder 3 is coupled to the radio 1, the built-in power supply B2 of the tape recorder 3 is disconnected due to the coupling action, and the built-in power supply B1 of the radio 1 is used as the drive power source for the tape recorder 3. It has become.

This is because the drive power source B1 built into the radio 1 has a larger capacity than the drive power source B2 built into the tape recorder 3, so the power source B1 of the radio 1 is used.

From the electrical circuit of the radio 1 configured in this manner, the mounting portion 2 to which the tape recorder 3 is connected is connected.
Connection terminals 1a to 1e for connection to the electric circuit of the tape recorder 3 are arranged within the tape recorder (see FIG. 1).

That is, when the tape recorder 3 is installed, the output connection terminal 1a for applying a part of the received No. 4 of the radio 1 to the recording input terminal 3a of the installed recorder, and a part of the playback output of the installed recorder 3 are connected to the recording input terminal 3a of the installed recorder. A connecting terminal 1b for connecting to the amplifier 13 of the radio 1, and a connecting terminal 1C for connecting the power source B1 inside the radio 1 to the electric circuit of the installed recorder 3.
and the above-mentioned switch S3 provided in the mounted recorder 3.
Connecting terminals 1d and le connected to the mounting portion 2 are disposed within the mounting portion 2.

Each of these terminals 1a to 1e is connected to an electric circuit within the radio 1 as follows.

That is, the connection terminal 1a is connected to the input end of the amplifier 13 via the amplifier 16.

The amplifier 16 amplifies a part of the received signal from the radio 1 to the recording input terminal 3a of the recorder 3 and applies it to the terminal 3a. The signal applied from the microphone 25 to the amplifier 13 of the radio 1 serves to cut this.

Is this the output of microphone 25? Radio 1's amplifier 1
If the width is increased by 3, there is a risk that howling will occur, so this is provided to prevent this.

Further, the connection terminal 1b is connected to the fixed terminal S1C of the switch S1.

The connection terminal 1C is formed of a plug, and is connected to the constant voltage circuit 17. and are connected via the switch S2.

Further, the connecting terminal 1d is connected to the fixed terminal S2b of the power switch S2, and the connecting terminal 1e is connected to the movable contact piece S2a of the power switch S2.

The electric circuit of the radio 1 and the connection terminal for connection thereof are configured in this manner.

On the other hand, the micro tape recorder 3 attached to the attachment part 2 of the radio 1 has each of the connection terminals 1a to 1a of the radio 1.
Connection terminals 3a to 3e (see FIG. 2) corresponding to radio 1e are provided, and these terminals 3a to 3e automatically connect ( It is designed to be connected to each of the terminals 1a to 1e in the second mounting portion 2.

Further, the electric circuit of the micro tape recorder 3 having the connection terminals 3a to 3e as described above is configured as shown in FIG. 2, for example.

That is, in FIG. 2, the electric circuit in the block indicated by the two-dot chain line 3f is the electric circuit of this ultra-compact tape recorder 3, and its main components are, as is well known, a recording/playback magnetic head 21. Amplifier 22.23, speaker 24,
It is composed of a built-in microphone 25, a jack 26 for connecting an external microphone, and the like.

In the recording state, the selector switches S4 to S7 are
As shown, each movable contact piece 54a-37a is switched to one fixed contact point 54b-57b, respectively.

Therefore, when there is a recording input signal to the external microphone (not shown) connected to the jack 26 or the built-in microphone 25, the signal is applied to the amplifier 22 through the fixed contact S4b of the switch S4, and the signal is amplified. Vessel 22.2
3, through the fixed contact S6b of the switch S6,
The signal is applied to the magnetic head 21 via a resistor 27 and recorded on a tape.

At this time, a bias is applied to the spatula 21 by the oscillator 28.

Also, during playback, by switching each movable contact piece 54a-37a of the changeover switches S4-S7 to the other fixed contact 54C-57C, the tape playback output signal of the magnetic head 21 is applied to the amplifier 22, and the same Widget and magnifier 2
The reproduced output signal amplified by 3 is outputted from the speaker 24 via the earphone jack 29.

Note that the resistor 30 is a resistor for adjusting the volume.

Moreover, the built-in power supply B2 is normally connected to the electrical circuit configured in this way via the main switch S through the terminal 3C configured as a jack.

The above-mentioned main switch S and the above-mentioned switch S3 are designed to be closed in conjunction with the recording/playback operation button 9 (see Figure 1), or opened in conjunction with the auto-stop mechanism when it is activated. .

An auto-stop mechanism operates in a tape recorder to automatically stop the tape recorder when a feed of the tape ends.

The connection terminals 3a to 3C are connected to this electric circuit as follows.

That is, the connection terminal 3a is connected to the built-in microphone 25 and the output end of the jack 26.

Further, the connection terminal 3b is connected to the output end of the amplifier 22 via a changeover switch S8.

The changeover switch S8 is a switch for guiding a part of the tape playback output to the radio 1, and when the movable contact piece S8a is switched to the fixed contact S8b, a part of the tape playback output is routed through the switch S1. is guided to the amplifier 13 of the radio 1, and the reproduced sound is also output from the speaker 5 of the radio 1.

However, in normal life, the switch S8 is switched to the fixed contact Ssc.

Further, connection terminals 3 d and 3 e are connected to both ends of the switch S3.

This switch S3 is opened and closed in conjunction with the main switch S.

Therefore, it is closed while the tape recorder 3 is in operation, but when the tape has finished feeding and the auto-stop mechanism is activated, it is opened in conjunction with the opening of the main switch S.

This serves to eliminate the need for a timer for setting the operating time of the radio 1.

That is, this switch S3 is used for radio 1 and recorder 3.
It is inserted into the power supply circuit of the machine and turns off the power to radio 1 and recorder 3 when the tape has finished being fed, so it is also called a sleeve switch and functions as a timer.
This has the effect of eliminating the need to provide a timer on the radio 1.

In addition, the connection terminal 3C is composed of a jack that corresponds to the connection terminal 1C of the radio 1, and when the terminal 1C is connected to this terminal 3C, the built-in power supply B2 is automatically turned on. It is meant to be separated.

The electrical circuit of the tape recorder 3 is configured as described above.

Therefore, as shown in FIGS. 1 and 2, the mounting part 2 of the radio 1
When this ultra-small tape recorder 3 is mounted, the terminals 3a to 3e of the recorder 3 automatically contact and connect to the terminals 1a to 1e exposed in the mounting portion 2, respectively.

Therefore, the tape recorder 3 is connected to the radio 1 in a cordless manner.

At this time, when connecting terminal 3C is connected to connecting terminal 1C,
The built-in power source B0 of the radio 1 is connected to the electric circuit of the tape recorder 3 via the constant voltage circuit 17 of the radio 1 and the power switch S3, and the built-in power source B2 of the recorder 3 is disconnected.

Radio 1 and tape recorder 3 are thus coupled and operate as described above.

However, from the radio 1 to which the small tape recorder 3 can be detachably connected, the connected recorder 3
If you remove this, not only will the timer function of Radio 1 by this tape recorder 3 be removed,
The tape recorder installation part of radio 1 becomes a blank space, and the appearance of radio 1 becomes unsightly.

Therefore, in the present invention, in order to eliminate this drawback, a timer formed approximately the same size as the tape recorder 3 is attached to the mounting portion 2 of the radio 1 which is now a vacant space, and the operation of the radio 1 is controlled by the timer. and controllable by
The appearance of the radio 1 after the tape recorder 3 is removed is supplemented by this timer to improve its appearance.

This timer 31, as shown in FIG.
The time setting knob 32 provided on the top of the surface (see figure) is rotatably provided with respect to the timer main body 31a.

Also, a scale disc 32 provided integrally with this knob 32
The time setting scale 32b engraved on is designed like a clock.

Therefore, the operating time of the timer 31 is determined by rotating the knob 32 and matching the desired operating time with the indicator 33, thereby operating the timer in the same manner as a known timer.

Furthermore, an operating switch SO is provided below the knob 32 on the front surface.

If this switch SO is turned on, the switch ST of the timer 31 (see Fig. 5) will be turned on after the time set by the knob 32, and if the switch SO is turned off, the setting will be turned on. After the time has elapsed, the switch ST of the timer 31 is a timer switch ST that turns off.

The bottom surface (see FIG. 4) of the timer 31 when attached to the radio 1 has electrical connection terminals 1d and 1e exposed in the attachment part 2 of the radio 1. Electrical connection terminals 31 d and 31e are provided.

An electric circuit within the timer 31 is connected to the electrical connection terminals 31 d and 31 e, as shown in FIG.

That is, the movable contact piece SOa of the operating switch SO is connected to the electrical connection terminal 31d, and the electrical connection terminal 31e is connected to the timer switch ST.

In addition, both rotational contacts SOb and S of the above-mentioned operating switch SO
Oc are connected to the a contact and the b contact of the timer switch ST, respectively.

The a contact point is located at a position where the timer switch ST is in the on state when the set time of the timer 31 is zero,
The position of the b contact is determined when the time is set on the timer 31.
The timer switch ST is in the on position.

When the timer 31 configured in this manner is attached to the mounting part 2 of the radio 1 as shown in FIG. The timer 31 is connected to the power circuit of the radio 1 by contacting the electrical connection terminals 31d and 31e of the radio 1.

That is, the timer switch ST of the timer 31 is connected to the radio 1 in the same way as the switch S3 (see FIG. 2), which opens and closes in conjunction with the auto-stop mechanism of the tape recorder 3.

Therefore, the timer 31 is installed in this way, the desired time for operating the radio 1 is set in the timer, and then the switch S2 of the radio 1 is switched and the movable contact piece S
2a to the fixed terminal S2d of the sleeve switch, the built-in power supply B1 of the radio 1 will be connected to the electric circuit in the first radio via the timer switch ST and the operating switch SO of the timer 31.

Then, the connection of the power source B1 to the radio 1 is controlled according to the switching state of the operation switch SO of the timer 31 and the time set in the timer switch ST.

For example, if the set time is set to 20 minutes by turning on the switch SOb, the timer switch ST will open when the 20 minutes have elapsed, so the radio 1 will only operate for 20 minutes.

Further, in this case, if the switch SO is turned off to SOc, the radio 1 starts operating after 20 minutes have elapsed.

In this way, the operation of the radio 1 can be freely controlled by the timer 31.

Therefore, according to the present invention, the following remarkable effects are achieved.

(1) By attaching a timer, defects in the appearance of the radio when no tape recorder is attached can be compensated for, and the appearance of the radio can be improved.

(2) With the tape recorder's sleeve switch, the power to the radio cannot be turned off until the tape has finished feeding, so the time is fixed at a certain time, but if you attach a timer, the radio can be turned on at any time. can be controlled.

(3) Since the radio is pre-installed with electrical connection terminals for coupling to a tape recorder, this can be skillfully utilized to construct a timer, so the timer device can be provided with simple accessories. be able to.

As described above, according to the present invention, a very practical timer device for electronic equipment can be provided.
