Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] This invention is applicable to small electric appliances, especially batteries. Regarding the source.

[Prior Art] Usually, this type of small electric device has a battery storage section recessed in the circumferential surface of the main body case, and the opening is covered with a battery cover so as to be openable and closable, thereby making it possible to replace the battery.

[Problems to be Solved by the Invention] However, due to the overall structure of the device, the battery storage section often has to be placed in a recessed location such as on the back of the device. Therefore, when replacing the battery, the device must be turned over. As a result, there was a strong risk of accidentally touching the switch of the operation part for accessing the A-device.

[Means for Solving the Problems] The present invention has been made in view of the above problems, and has the following features:
As shown in the figure, in a small electric device that is equipped with a battery storage section and an operation section on the circumference of a main body case, and an insertion opening of the battery storage section is covered with a lid so that it can be opened and closed, the battery storage section and the operation section are close to each other. The present invention is characterized in that the lid body is arranged so as to cover the operating section when the lid body is opened.

[Function] With the above configuration, when the lid covering the two-battery storage section is opened, the lid is positioned to cover the operating section, contrary to the state before opening. Therefore, even if the battery is replaced in such a state, contact with the operating section is forcibly prevented.

[Embodiment] Figures 1 to 7 show an example in which the present invention is implemented in a doll-shaped timer device 1 that emits a predetermined sound when a set time comes, but the present invention is not limited to this, and can be applied to various small electric devices such as a portable radio. Of course, it can also be implemented in substantially the same way.

The timer device 1 according to the present invention, as shown in FIG.
It is composed of a timer unit 2 and a character doll 3 that houses and holds the unit 2 inside.

The character doll 3 is a three-dimensional representation of a character such as a human child or an animal, and a protrusion 5 such as a belly button protruding from the whole or at least from the center of the front is made of a soft material such as a synthetic resin material. Formed from members. Further, a storage part 6 large enough to fit the timer unit 2 is formed at the back side of the protrusion 5 at the bottom of the doll 3, and an open lower opening leading to the storage part 6 is provided on the lower side of the doll 3. . Further, the protrusion 5 is formed with a fitting hole 5a into which the tip 9 of the operation switch 13 protruding from the front side 8 of the timer unit 2 is tightly fitted. By inserting the operation switch tip 9 into the fitting hole 5a, the timer unit 2 is securely held within the doll 3, and the switch can be operated from the front side of the doll 3.

As shown in FIGS. 1 and 3, the timer unit 2 has a
The upper case 10 and the lower case 11 are joined together to form a flat hollow cylindrical body case 12, and inside the body case 12 there are operating switches 13, which will be described later. An electric circuit including a speaker 14 and a circuit board 15 is provided. Furthermore, a battery storage section 17 and a timer setting section 18 are recessed on the lower surface 16 side of the lower case 11, so that when the timer unit 2 is stored in the doll 3, 5. The battery 20 can be replaced or the setting switch 34 can be operated through the open lower door.

The battery storage section 17 has a size that can accommodate, for example, four AA size dry batteries 20 in parallel, and the opening 21 is for storing batteries M.
22 and is covered in a manner that can be opened and closed freely.

The battery 122 has a rectangular thin plate shape that substantially coincides with the opening 21 of the battery storage section 17, and has rotating shafts 23, 23 protruding toward both sides from the proximal side surface of the battery 122, and is adjacent to the battery storage section 17. Slide grooves 24 on both sides of the timer setting section 18
A rotation shaft 23 is slidably and rotatably supported in the slide groove 24. Further, on the leading edge of the battery 122, finger hook protrusions 26 are formed on both sides with the locking claw 25 in the center, while finger hook protrusions 26 are formed at corresponding positions on the lower case 11 side when the battery 122 is closed. A substantially hemispherical finger hook groove 27 whose half is covered by the portion 26 and a locking groove 28 into which the locking pawl 25 is removably fitted are formed.

When the battery cover 22 is in the closed state, insert your finger into the finger hook 7427 and slide it in the direction of the timer setting part 18 by the length of the slide groove 24, so that the locking pawl 25 and the locking groove 28 are engaged. After untying, by lifting the finger hook projection 26, it is released as shown by the dotted chain in FIG. 1(b).

The timer setting section 18 forms a groove 29 adjacent to the battery storage section 17 and includes a battery 122 in the groove 29.
Four through-holes 30 are formed perpendicularly to the sliding direction. On the other hand, a bush switch 31 is mounted on the opposite position on the circuit board 15, a base end 33a of a cap-shaped switch button 33 is fitted into the suppressing part 32 of the switch 31, and a tip 33b of the switch button 33 is inserted into the through hole. 30
Four sets of setting switches 34 are formed so as to protrude from the periphery, and the switch 31 on the circuit board 15 is indirectly turned on via the switch button 33. Furthermore, by writing the operation contents 35 of each setting switch 34 on the surface of the battery cover 22 at a position corresponding to each through hole 30, it is possible to add or change setting functions when the operation of the electric circuit is controlled by a program. We are able to respond immediately to such matters.

The operation switch 13 has a flange 37 at the tip of a substantially rectangular cylindrical press contact 36 and a tlvJ plate 38 on the base end side, and the press contact 36 is provided in a guide groove 39 formed between the upper and lower cases IO and 11.
At the same time, by fixing the mounting part 40 connected to the swing plate 38 in an abbreviated shape via the hinge part 41 to the upper case 10, the swing plate 38 is assisted by using the hinge part 41 as a fulcrum. The direction of the plate 42 is swung. The auxiliary plate 42 is fixedly arranged on the upper case 10 substantially parallel to the swing plate 38, and a spring body 44 is interposed between the opposing protrusions 43, so that the swing plate 38 can be fixed to the main body. The outward direction of the case 12 is always biased. Also, from the swing plate 38 to the auxiliary plate 4
A suppression shaft 45 is provided protruding toward the direction of the auxiliary plate 42.
A guide hole 46 through which the pressing shaft 45 passes is provided at a corresponding position, and a bushing switch 31 is provided on the circuit board 15 close to the front surface of the guide hole 46. In the operation switch 13 having the above configuration, the flange 37 at the tip functions as a retainer when the timer unit 2 is housed in the doll 3.
When the "navel" portion 5 is pressed against the spring body 44, the pressing shaft 45 moves forward, but the direction of movement of the pressing shaft 45 is corrected by the guide hole 46 of the auxiliary plate 42, so that the button switch 31 can be moved accurately. The suppressor 32 can be turned on.

FIG. 4 is a block diagram schematically showing an electric circuit used in the timer unit 2, in which a central processing unit (CPU) operated by a program is used as the center of control, and the central processing unit 50, RAM 51, ROM
A control unit 56 is configured by connecting a storage device 53 such as 52 and an input/output device 54 via various paths 55. Furthermore, the input/output device 54 includes a display section 60 including a voice generating device 57 and a melody generating device 58, or a control section 5.
By connecting a switch section 61 that allows an operator to directly access the control section 6, various timer operations such as various reservation settings or sound generation by the display section 60 at the reservation time are possible.

FIG. 5 shows an example of a more specific electric circuit.

A microprocessor that integrates into one chip a CPU 50 that operates as a central processing unit, a RAM 51 that serves as a work area, a ROM 52 that stores % line programs in advance, and an input/output device R54 that receives and transfers data to and from external circuits. (for example, μPD7507CS) is used as the control section 56, and when a reset signal is input from the differentiating circuit 63 to the reset terminal RESET at the same time as the battery 20 is set in the battery storage section 17, the program in the ROM 52 is programmed according to a predetermined procedure. In addition, each port PlI provided in the input/output device 54
Switch unit 61 and audio generator 57 via a to Ps3
Data is received and passed between the melody generating device 58 and the melody generating device 58.

As described above, the switch section 61 includes one operation switch 13 that is operated from the front surface 8 side of the main body case 12 that houses the timer 22, and four setting switches 34 that are operated from the lower surface 16 side of the main body case 12. It consists of For each switch 13 and 34, a normally open on/off switch 31 is used, and one end is connected in parallel to the power supply section 64.
and connect the other end to the control unit 56 by connecting it to the resistor 65 and grounding the other end.
When each switch 13, 34 is turned on, the rHJ signal is applied to the control unit 56 to notify the operating status of the switch.

As the voice generating device 57, for example, an LC8100, which is a PARCOR type voice synthesis IC, is used. 5 TAR
In conjunction with the input of the start signal from the control unit 56 to the T terminal, the control unit 56 controls the word selection terminals Cn to C4.
A series of words such as "good morning" and "good night" specified by the four-digit double-certificate signal applied from the output terminal DA are output from the output terminal DA.

The melody generator 58 uses a so-called melody IC such as SVM7973. When a three-digit binary signal is applied from the control unit 56 to the melody selection terminals MSI to MS3, the melody specified by the value of the binary signal is applied in conjunction with the application of the start signal to the start terminal MT. is output,
It is possible to force a stop by applying a stop signal to the STP terminal.

The output signals from the voice generating device 57 and the melody generating device 58 are input to the amplifier 59 and amplified to a predetermined magnitude, and then are sounded by the speaker 14 attached to the upper case 10.

Note that the power supply terminal Vcc of the amplifier device 59 is connected to a switching transistor 6 that can be turned on and off under control from the control section 56.
It is connected to the power supply section 64 through a switching section 62 equipped with a power source 6 and a changeover switch 69 that turns on and off in conjunction with the insertion and removal of the plug into and from the jack 67.
7 or only during the period when the melody generator 58 is in operation, the transistor 66 of the switching unit 62 is turned on to prevent excess power consumption in the amplifier 59, but when the plug is inserted into the jack 67, the amplifier 590 input When the side and the audio output terminal of a television etc. are connected, the amplifier 59 is forcibly turned on regardless of the operation of the control unit 56.
is turned on so that it also operates as a normal amplifier. Note that the control unit 56 is controlled by the on/off operation of the amplifier device 59.
In order to prevent the applied voltage from fluctuating, a large-capacity smoothing capacitor 70 and a separation diode 71 are connected to the power supply section 64.

6 and 7 show the flow of control of the entire electric circuit by the program stored in the ROM 52 of the control unit 56. FIG.

FIG. 6(a) schematically shows the overall control flow, starting the program (step 80).
Then, the work area or stack area in the RAM 51 is initialized (step 81), and reference time measurement is started.Furthermore, in step 82, it is determined whether or not it is necessary to test the entire circuit. is YE
If the answer is S, test processing A to be described later is performed, but if the answer is NO, the process enters a standby state in which it is possible to accept input from the switch unit 61 (step 83), and the reserved time is reached in this standby state (step 83). 84) and alarm processing B according to the preset reservation details, and the word selection, weekly reservation, daily reservation, and reservation cancellation setting switches 34 provided in the timer setting section 18 provided on the bottom surface 16 side of the timer unit 2. Or a character
When it is determined that the operation switch 13 protruding from the front of the doll 3 is turned on, each switch operation (step 8
After the data processing (C-F) corresponding to steps 4 to 89) is performed, the process returns to the standby state in step 83.

FIG. 6(b) shows the flow of an interrupt subroutine that checks whether or not the switch has been operated, updates various counters, and checks reserved times. In this embodiment, such interrupt processing is forcibly performed every 0.25 seconds, except when the interrupt is disabled.

When entering the subroutine (step 101), step 1
After the value of the minute counter is decremented by 1 in step 02, it is determined in step 103 whether or not the f value of the counter has become 0. 81) and step 104, the minute counter is preset to a value of 239, and an interrupt process is performed every 0.25 seconds to subtract the set value by 1 (step 102), and even if the determination in step 103 is NO, If the answer is YES, it is determined that one minute has passed since the previous count, so in the next step 105 the current time is advanced by one minute, and in steps 106 to 110, the current time is The presence or absence of an alarm request is determined.

That is, the reference time and the reservation time are compared every minute after the reference time (step 107), and if it is determined in step 108 that the two match, the start address of the reservation area where the reservation details are stored is set as an alarm. The area is set (step 109). In this embodiment, up to three sets of alarm requests can be set in the alarm area, and three sets of reservations can be made, including different alarm requests at the same time, or requests that timed up during alarm processing but not at the same time. It is now possible to reserve time in the control unit 56 at all times. Therefore, when the alarm area is full as determined in step 106 and all reserved times have been checked in step 110 to see if any more reservations can be made, the next step Move to 111.

Steps 111 to 115 are processing steps for various timer counters that are set and used in the program, and in step 111, it is determined that the 20 second or 3 minute timer is operating because the timer flag is set. For example, set the value of the timer counter to 1.
(Step 112). Next, if it is determined that the value of the timer counter becomes 0 and has counted up, the timer flag is cleared and returned to the initial state (Step 114). Next, set the count value of the 2 second or 5 second timer to minus IL (step 1).
15) Then, the timer processing ends.

Steps 116 to 118 are steps for inspecting switch operation status.

That is, the switches 13 and 34 are read and checked in step 116, and only when it is determined in step 117 that the switch has changed from the off state to the on state, the switch flag is set (step 118), and the subroutine exits. exit (step 119), therefore the interrupt processing rate by the subroutine is 0, 25.
The on/off state of the switch is sampled every second, and even if the same switch is pressed continuously or the switch chatters, the control unit determines that it is a single switch operation and prevents malfunctions.

FIG. 7(a) shows an example of the flow of the test process in FIG. 6(a), and when the process starts,
To automatically check the operation of various timers used in a program and the voice or melody generation operation on a display section to detect abnormalities in the operating status of the entire circuit.

When the process is started (step 12o), the amplifying device 5
9 was activated (step 121), a 20 second timer was started (step 122).Next, the words specified by numbers 3 and 12 were output from the voice generator 57 at 1 second intervals ( After steps 123 to 126), the melody generator 58 generates melodies 1 and 6.
(Steps 127 to 131), each melody is outputted from L and the entire song is not output, but when 3 seconds have elapsed from the start, a 5TOP signal is given to the melody generation bag W158 to forcefully stop it (Step 132). ~134
), and further determines the time-up of the 20 second timer in step 135, and outputs the first word (step 136).
Furthermore, the test processing is completed at step 137) by stopping the amplifying device 59 (step 138).

FIG. 7(b) shows the flow of alarm processing B when alarm request data is set in the alarm area due to the reservation time and current time matching during the interrupt subroutine in FIG. 6(b). , starts processing (step 140), and step 141
If it is determined that the 2-second or 5-second timer is already running, step 142) is performed to clear the switch area after setting a certain interval between the previous process and the previous process by waiting until the timer times out. Switch section 61
It is possible to accept input from the computer, clear the word selection and alarm end flags (step 143), and turn on the power to the amplifier 59 (step 144).
After completing the preparation for alarm processing, proceed to the following steps 145 to 145.
The process moves to the alarm display cycle indicated by 167.

In step 145, the number of alarm repetitions is first set in accordance with the content of the alarm to be displayed. In step 159, a melody arranged from a well-known song that lasts for a predetermined period of time is sequentially pronounced in each voice consisting of words, and in step 147.1 between each pronunciation.
2 by activating the 2 second timer at 52.163.
A time interval of seconds is set as one display cycle. Then, for the selected MM's wake-up call of "Good morning" and good night call of "Good night," the above cycle is repeated three times, and if any other words are selected, a cycle is executed in which the message is displayed only once. After that, the alarm display cycle is exited and the process proceeds to step 168 based on the judgment in step 165.

Also, if it is determined in step 155 that the code number of the reserved word is 1 or 2, ``good morning'' or ``good night'', the melody corresponding to the word is selected in step 158, but in the case of other words, , step 1
The value of the melody counter is sequentially shifted in steps 56 and 157, so that the number of songs is changed every time alarm processing is performed.

Furthermore, the 2 seconds of silence between each pronunciation (steps 149 and 15)
4.167) and when the melody is sounded (step 161)
Only in this case, the signal input by pressing the operation switch 13 protruding from the front of the character/puppet 3 is accepted, and even if the cycle is in the middle of displaying an alarm, the cycle is exited and the process moves to step 168. Even so, the 5TART signal applied to the melody generating device 58 is stopped in steps 168 to 172, and the 5TOP signal is sent at the same time, so that the melody being displayed can be forcibly stopped.

When the display cycle is completed as described above, first a 5-second timer is started (step 173), the switch area is cleared (step 174) to allow switch input to be accepted, and then the above-mentioned alarm is displayed in step 175. At the same time, in step 176, the number of alarm request data is -
After 1, it is determined in step 177 whether or not the requested data remains in the alarm area. If the determination is YES, it means that all alarms that require processing at this point have been processed, so the amplifier 59 is stopped (step 178), the alarm end flag is set (step 179), and the process continues for another 3 minutes. By starting the timer (step 180) and clearing the switch area (step 181), cancellation of the reservation can be accepted and alarm processing B is ended (step 182).

If the determination in step 177 is No, it is known that there are multiple reservations made for the same time, or that there are other reservations that timed up during alarm processing.
In step 183, the alarm request data is shifted one step and the next data is retrieved. In this embodiment, the retrieved data is not processed immediately until the 5 second timer started in step 173 times out in step 189. Accept the input of the cancel switch (step 18)
4) When the cancel switch is turned on, the reservation of the executed alarm saved in step 175 is cleared, step 185) is canceled, and a melody of the processing success image is outputted in step 186), and the switch area is is cleared (step 187), and the 2-second timer is started (step 188) to complete step 1.
A time interval of 2 seconds is forcibly provided from the melody output of 86. If it is determined in step 189 that the 2 second or 5 second timer has timed up, step 19
After clearing the switch area with 0, go to step 1 again.
The process returns to step 45 and executes an alarm display cycle for the next alarm.

FIG. 7(C) shows the word selection process C in FIG. 6(a).
The process starts (step 191).
Then, in step 192, the controller 56 sends an on signal to the transistor switch 66 to activate the amplifier 59, and then, in step 193, it is determined whether or not the word selection switch was turned on while the 20 second timer was counting. Ru. If this determination is YES, it is determined that the word selection switch has already been turned on within 20 seconds and the word selection process C has been performed, and the display of the next word is requested, so the word selection code is Advance the number by 1 (step 194)
Also, set a 20-second timer and flag (step 195) to make it possible to receive and receive other processing commands such as reservation and cancellation, and issue an N-leaf output request to the voice generator 57. (Step 196), the word specified by the word selection code number is output. After that, the operation of the amplifier device 59 is stopped (step 197), and the switch area is cleared (step 198), so that the next switch pressing operation can be accepted (step 199).
.

FIG. 7(d) shows the flow of the reservation process in FIG. 6(a), and the reservation process starts (step 200).
First, in step 201, it is determined whether or not the 20 second timer is counting.

If this determination is No, the switch area is immediately cleared (step 208) and the process ends without performing the reservation process. However, if the determination in step 201 is YES, it is determined that the word to be processed next has been spontaneously selected by pressing the word selection switch and performing the word selection process C described above, and the process proceeds to the following reservation process. .

After resetting the counting 20 second timer and flag in step 202, the amplifier 59 is activated (step 203), and the reserved area is checked (step 203).
Step 204) If it is determined in step 205 that there is no vacancy in the reservation area, the number of reservations exceeding the specified number has already been made and no more reservations can be made, so the melody generating device 58 generates a melody with an image of failure. After outputting (step 206), the amplifying device 59 is stopped (step 207), and the process ends.

On the other hand, if the determination in step 205 is YES, interrupts are prohibited between step 210 and step 212, and the current time and week number are imported (step 21
1) Also, set the time and week number of the date in the reserved area (step 213).

Note that the current time and week number may correspond to Japan Standard Time, but in this embodiment, the time when the battery 20 is set is used as a reference, and each day is expressed in minutes from 0 to 1439. The current time is expressed as , and the day of the week is specifically displayed by associating each day of one week from the reference time with a week number from 1 to 7.

Next, in step 214, it is determined whether the word selected prior to the reservation process is a special word representing "start" such as "hajimaruyo".

If the determination is NO, proceed directly to the next step 216.
If the answer is YES, the reservation time set in the reservation area in step 215 is forcibly set back by 5 minutes, so that when the timer is activated and the alarm is processed, the television program, etc. is actually displayed. Starting at 5
This makes it possible to notify the user several minutes in advance so that preparations for program recording, etc. can be made sufficiently.Next, in step 216, it is determined whether the reservation content is a daily reservation content such as a wake-up call (see FIG. 6). It is determined from the contents of the switch area whether the weekly switch was turned on in step 86 or the daily switch was turned on in step 87 of a), and if the determination is YES, the week number set in step 213 is set to 0. It is displayed that it is a daily reservation (step 217). Furthermore, in step 218, FIG.
After completing the reservation for one group by setting the code number corresponding to the word displayed during the word selection processing shown in C) in the reservation area, the step of issuing a request to the melody generator 58 to output a melody with a success image. 219), the operator is informed that the reservation has been successfully made.

Thereafter, in step 22, the power supply to the amplifier device 59 is stopped.
0), clear the switch area (step 221)
The series of reservation processing ends (step 222).

FIG. 7(e) shows the flow of the cancellation process E in FIG. 6(a). When the process is started (step 230), a driving voltage is first applied to the amplifier device 59 and the amplifier device 59 is activated. Then, in step 232, it is determined whether the 3-minute timer is counting. The 3-minute timer is set at the end of the alarm processing B described above, and if the determination is YES, it is understood that three minutes have passed since the end of the alarm processing B. In such a case, proceed to step 233 to reset the 3-minute timer and the relevant flag (step 233), and then import the execution address for alarm processing saved in step 175 of FIG. 7(b) (step 233). Step 23
4) Furthermore, the reservation area corresponding to the execution address is cleared in step 235) to erase the reservation contents for which the alarm processing has been completed.

On the other hand, if the determination in step 232 is No and the cancel switch is pressed regardless of alarm processing, it is further determined in step 236 whether or not the 20 second timer is counting. The 20 second timer is set only when a predetermined word is selected during the word selection process in step 195 of FIG. The device 59 is stopped and the process ends (step 239), but if the determination is YES, it can be determined that the cancellation process is actively desired, so the process moves to the following step 240 and the cancellation operation is performed.

First, in step 240, after resetting the 20 second timer and flag to return to the initial state, 9! ! ! The OK flag for determining and displaying whether or not the process was successful is reset (step 241). Next, in step 242, the first address in the reserved area is set, and the word selected during the word selection process prior to the cancellation process is set. A determination is made in step 243 as to whether or not they match. If this determination is NO, the process moves to step 246 to set the address of the next reserved area, and the determination in step 243 is continued until the entire reserved area has been checked in step 247, but the process proceeds to step 246.
If the determination in step 43 is YES, clear the corresponding reservation area (step 254), set the OK flag (step 245), and sequentially perform the cancellation process to erase all reservations for the same M-candy. .

Next, in step 248, it is determined whether the OK flag is 1 or not, and if the determination is YES, it is determined that at least one reservation cancellation has been executed in step 244.
In step 250, a melody with an image of success is output from the melody generator 58, and if the answer is No, it is determined that the corresponding reservation was not found and the reservation was not canceled at all, so a melody with an image of failure is output. is requested from the melody generator (step 249).

Thereafter, a two-second timer is started in order to provide a time interval between the next display operation (step 251), the amplifier 59 is stopped in step 252), the switch area is cleared in step 253), and the cancellation process E is performed. Exit (
Step 254). .

FIG. 7(f) shows the flow of the play process F in FIG. 6(a), except when the operation switch 13 of the timer unit 2 is pressed during a specific period during alarm processing. The process is started, and a melody or words can be randomly output in conjunction with the suppression operation of the operation switch 13. That is, the process starts (step 2
60), and after starting the amplifier 59 (step 261), the current time is taken in (step 262). Here, in the data table, data such as code numbers that specify the melody and words to be output or the display contents are randomly set in advance, and the step is performed using the current time value obtained in step 262. 263
The address in the data table is calculated in step 26, and the data in the data table is extracted from the address.
4) In step 265, if the extracted data is a word, an output request is sent to the voice generator 57.Step 266) If it is a melody, the melody generator 58 is output.
After issuing an output request to (step 267), the power supply to the amplifier device 59 is stopped (step 268), the switch area is cleared (step 269), and the process ends (
step 270).

The above-mentioned sound is generated continuously every time the operation switch 13 is pressed, and the displayed content is randomly selected from a group of reserved words or melodies, so it is full of surprises. Acoustic display is performed using a combination of numbers or melodies.

[Effects of the Invention] As described above, in the present invention, when the battery cover is released, the operation part is covered with the cover, so that accidents such as touching the operation part and erroneous operation when replacing the battery can be prevented.

Furthermore, by writing the operation contents of the operating section on the lid, even in the case of program-controlled electrical equipment where functions can be easily changed or added, minor changes such as replacing the lid can be made immediately.

Furthermore, by forming the spherical finger hook protrusion on the lid, the lid can be opened and closed easily and can also be used as a foot when installing equipment.
