The light emitting diode (LED) 17 is used not only for transmitting and receiving data, but also as a display which emits light when sound is input or output during recording or reproduction. Therefore, the light emitting diode contains a large amount of visible light component, and has a peak wavelength of, for example, 500 nm to 1000 nm, preferably 600 nm to 8 nm.

When 1 is ON, a ground signal is supplied to the memory control circuit 7, and in response to this, the memory control circuit 7 informs the main control circuit 6 that data cannot be written to the memory card 33.

FIG. 4 is a sectional view showing a state in which the memory card 33 is mounted on a card mounting portion of the apparatus main body. A circuit board A (50) of the memory card 33 is provided with a group of electrical connection contacts 52 for electrically connecting to a circuit board B (51) fixedly mounted inside the apparatus main body. . The circuit board B (51) is also provided with an electrical connection contact group 53.

In the upper part of the apparatus main body, an opening 54, which constitutes a card mounting portion and in which the memory card 33 can be inserted, is provided.
Is provided. At the front end side of the opening 54, an eave-shaped engaging portion 5 into which the front end portion 55 of the memory card 33 can be inserted.

0) is provided with a rubber connector 57 for electrically connecting the circuit board B (51) of the apparatus main body.
The rubber connector 57 is held by a guide 58 provided with a D13 terminal, and the rubber connector 57
, A D12 terminal for electrically connecting one of the contact groups 52 and one of the contact groups 53 extends. These terminals are made of a conductive elastic material, and the entire rubber connector 57 is formed by alternately laminating a conductive elastic material and a non-conductive elastic material at a minute pitch. In addition, this rubber connector 57
A stable conduction state is achieved by receiving a predetermined compressive force. That is, while the compression force immediately after the start of mounting the memory card 33 is small, the resistance value is high and the conduction is unstable. However, when the memory card 33 is mounted and receives a predetermined compression force, the resistance value decreases and a stable conductive state is established. .

In the above configuration, the memory card 33
When the memory card 33 is mounted on the card mounting portion of the apparatus main body, first, the memory card 33 is tilted, and the leading end portion 55 is inserted into and engaged with the eave-shaped engaging portion 56 provided on the apparatus main body. In this state, the memory card 33 is rotated about the leading end 55 in the direction in which the memory card 33 contacts the rubber connector 57, and the circuit board A
The contact group 52 of (50) is connected to the contact group 53 of the circuit board B (51) via the D12 terminal and the D13 terminal. In this state, the memory card 33 is locked. The mounting of the memory card 33 to the card mounting portion of the apparatus main body is not limited to such a method, and may be performed by mounting the memory card in the card holder in advance and moving the card holder to the card mounting portion. Good.

The recording / reproducing operation of the audio recording / reproducing apparatus having the above-described configuration will be described below. At the time of audio recording, an analog audio signal obtained from the microphone 1 is amplified by the microphone amplifier 2, the frequency band is limited through the LPF 3, and then converted to a digital signal by the A / D converter 4 via the analog switch 26. The signal is converted and input to the DSP 5 inside the main control circuit 6.

Here, when the audio signal input from the microphone 1 is higher than a predetermined reference level, for example, A /
When it is larger than -6 dB of the maximum range of the D converter 4,
When a pulse is output to the diode 21 connected to the terminal D11 of the main control circuit 6, electric charges are accumulated in the capacitor 22 and a voltage is applied to the transistor 24. As a result, the impedance between the microphone amplifier 2, the transistor 24, and the ground changes, the signal input to the microphone amplifier 2 is limited, and the gain is adjusted. The electric charge stored in the capacitor 22 is gradually discharged via the resistor 23.

Next, the DSP 5 compresses the input digital signal in accordance with the operation of a plurality of operation buttons and switches connected to the main control circuit 6, and compresses the compressed audio data into the main control circuit 6. The data is recorded in the semiconductor memory unit 10 through the D4 terminal. At this time, an address at which audio data is to be recorded is given to the memory control circuit 7 from the D3 terminal.
The write operation is controlled by the memory control circuit 7.

On the other hand, when performing reproduction, the main control circuit 6 reads out audio data recorded in the semiconductor memory section 10 under the control of the memory control circuit 7 and supplies it to the DSP 5 to expand it. The audio data expanded by the DSP 5 is D / A
The signal is converted into an analog signal by the converter 11 and the AMP 12
After that, the signal is output from the speaker 13 as sound.

In the above-described sound recording and reproducing operations,
The main control circuit 6 controls the drive circuit 9 to cause the display 8 to display various information such as an operation mode. The main operation of the above-described audio recording / reproducing apparatus will be described below based on the operation of the main control circuit 6 with reference to the flowchart shown in FIG.

When the battery 18 is set and power is supplied, the main control circuit 6 first initializes the external conditions of the main control circuit 6 and the internal storage unit (step S1). While the initialization is being performed, a character "CHECK" indicating that the initialization is being performed is displayed on the display 8 as shown in FIG. After completing the initialization, the main control circuit 6
Detects whether the power supply voltage of the battery 18 is at a rated value (step S2). At this time, the rated value is set to, for example, 1 V, and the main control circuit 6 determines that the power supply voltage of the battery 18 is 1
V, or whether the impedance of the battery 18 is higher than the rated value based on the current flowing through the battery 18
-Detection is performed based on information from the DC converter 20. That is, a detection signal relating to the state of the battery 18 is input to the D10 terminal of the main control circuit 6, thereby detecting whether or not the battery 18 has a usable capacity. As a result of the detection in step S2, when it is detected that the battery 18 is in a usable state, the relay switch 25 is turned on to determine whether or not the memory card 33 is mounted on the mounting portion of the apparatus main body. Card recognition processing (step S
Go to 23).

As a result of the detection in step S2, the battery 1
If it is detected that the battery 8 is not in a usable state, the power supply to the entire audio recording / reproducing apparatus is stopped, and a switch (not shown) provided between the battery 18 and each circuit is turned off. In addition, the fact that the battery 18 has no capacity is displayed on the display 8 (for example, a liquid crystal display unit) as a notification unit via the drive circuit 9. Then, it waits in this state until a usable battery 18 is set.

Next, the subroutine of the card recognition process shown in step S23 will be described with reference to FIG. When the process proceeds to the subroutine process from step S23 to step 30, first, it is determined whether the D13 terminal of the main control circuit 6 is connected to the memory card 33 (step S31). As a specific method of determination at this time,
It is determined whether or not the metal plate-shaped contact pad 59 exposed on the side surface of the memory card 33 and connected to the ground and the metal spring 79 connected to the D13 terminal are in contact with 79. If the voltage applied to the D13 terminal is the power supply voltage (H
i), the D13 terminal is connected to the memory card 3
It is determined that the connection is not made to the third contact pad 59, and the process returns to step S36.

On the other hand, if the voltage applied to the D13 terminal changes from the power supply voltage (High) to the ground (ground) voltage (Low), the D13 terminal is connected to the contact pad 59 of the memory card 33 via the metal spring 79. Then, the process proceeds to step S32.

According to this determination method, it is not necessary to constantly monitor the connection state between the contacts when the memory card 33 is inserted, and the power supply voltage is applied to the memory card 33 after the memory card 33 and the sound recording / reproducing device are securely connected. Can be supplied, so that destruction of data recorded in the memory card 33 can be prevented.

In step S32, the D12 terminal of the memory card connection portion of the memory card 33 and the terminals of the memory address signal line and the data signal line are connected to the main control circuit 6 via the rubber connector 57. The connection state between the D12 terminal of the main control circuit 6 and the memory card 33 is determined by the same method as that used to determine the connection state between the D13 terminal and the memory card 33 (step S32).

If the D12 terminal is not connected to the predetermined terminal pattern of the memory card 33 via the rubber connector 57, the process proceeds to step S36, and the D12 terminal is connected to the predetermined terminal pattern of the memory card 33 via the rubber connector 57. Step S3 if the terminal pattern is connected to
Move to 3. The processing in step S34, or the processing in steps S31 and S32,
It functions as a preliminary determination unit.

In step S36, a predetermined notification, for example,
The fact that the memory card 33 is not mounted on the card mounting section and the card is not mounted is displayed on the display 8 as notification means as shown in FIG. 7C. If the operation button is pressed by mistake while the memory card 33 is not mounted on the card mounting section, a warning sound, for example, 1 k
A signal with a duty ratio of 50% is emitted from the speaker 13 for 180 msec at a frequency of 60 msec.

Then, from step S36 to step S4
Then, the process goes out of this routine with the error information held, and goes to step S4 in the flowchart shown in FIG.

When it is determined that the memory card 33 is mounted on the card mounting section, the flow shifts to step S33, and waits for a predetermined time, for example, 1.5 seconds, before moving to the next processing.
The processing in step S33 functions as a control unit of the information recording / reproducing apparatus according to the second invention.

Next, the usable voltage of the memory card 33 is checked (step S34). If the voltage is suitable for use, power is supplied to the memory card 33 (step S35), and the voltage is inappropriate for use. Sometimes, the process proceeds to step S37.

That is, in step 34, the power supply voltage (5) that can be used by the memory IC incorporated in the memory card 33 is determined based on the shape of the voltage detecting recess of the memory card 33.
V, 3.3 V), and determines whether or not this memory card 33 can be used. For example, when the power supply voltage to be supplied is 3.3 V, the memory card 33 must have a 3.3 V specification.

Here, when the memory card 33 other than the 3.3V specification is inserted into the card mounting section, it is determined that the memory card cannot be used, and the process proceeds to step S37. In step S37, a predetermined notification, for example, as shown in FIG.
As shown in (b), an error is displayed on the display 8 as a notification means that the memory card 33 cannot be used.

FIG. 7 shows a display indicating that the memory card 33 is not loaded in the card loading section.
This is performed as shown in FIG. If an operation button is pressed by mistake while the unusable memory card 33 is loaded in the card loading section, a warning sound such as 1
A signal with a duty ratio of 50% is emitted from the speaker 13 for 180 msec at a cycle of 60 msec.

Then, steps S37 to S4
Then, the process goes out of this routine with the error information held, and goes to step S4 in the flowchart shown in FIG.

If it is determined in step S34 that the usable memory card 33 is loaded in the card loading section, the memory device information is detected from the memory card 33 (step S39), and the process proceeds to step S40.

That is, in step S39, the main control circuit 6 reads the register information of the memory as the memory device information in order to detect the type of the memory medium mounted on the memory card 33. Then, in step S40, the type of the memory medium is determined based on this information. For example,
E when the hexadecimal data read is 9888H
It is determined that it is an EPROM (flash memory), and the flow shifts to step S43. Even if the AA55H is used, it is determined that the AA55H is an EEPROM (flash memory) and the process proceeds to step S43.
After storing the information for recognizing the memory size (capacity) and the control method in the storage unit (not shown) of the main control circuit 6, the process proceeds to step S47.

If it is 9090H, it is determined that it is an SRAM, and the flow shifts to step S42. And
After storing information for recognizing the memory size (capacity) of the memory card 33 and the control method in the storage unit (not shown) of the main control circuit 6, the process proceeds to step S47.

If it is 0H, it is determined that it is a ROM or an EEPROM (flash memory) in which writing is prohibited, and the flow shifts to step S44. Then, after storing information for recognizing the memory size (capacity) of the memory card 33 and the control method in a storage unit (not shown) of the main control circuit 6, the process proceeds to step S47.

If the read hexadecimal data is other than the above-mentioned value, the flow advances to step S37 to execute FIG.
And a warning sound, for example, with a duty ratio of 50% at a cycle of 1 kHz and 60 msec.
Is emitted from the speaker 13 for 180 msec. Thereafter, the process shifts to step S45 to exit this routine while retaining the error information, and shifts to step S4 in the flowchart shown in FIG.

In step S47, predetermined management data written in the memory card 33 is repeatedly read in subsequent processing to determine whether or not the memory card 33 can be used for normal reading and writing. , The number of readings N is set to zero.

Next, the process proceeds to step S48, in which data written in advance at a predetermined address of the memory card 33, that is, valid information of the card, is checked in order to check whether the data lines of the memory card 33 are normally connected. Read. Then, control goes to a step S49. In step S49, it is determined whether or not the read data is normal. If the data is normal, the flow shifts to step S50 to read valid data of the address (step S50).

In step S49, using the memory management information, for example, "FTL (Flash Translation Layer)
If it is possible to read "100", it is determined that the data is normal. To read the valid data of the address, as in the case of checking the connection of the data line, all the address lines are switched and written in advance at a predetermined address of the memory card 33. Then, it is determined whether or not the data read in step S51 is normal, and if it is normal, it is determined whether or not the number of times of reading exceeds 10 times (step S51).
52) If not, the value of N is incremented by 1 and the routine goes to step S48.

In step S51, as in the case of the data line connection check using the memory management information,
For example, "FTL1" which is management data for each address line
If "00" can be read out, it is determined to be normal. If the number of times N has been read exceeds 10 in step S52, the flow shifts to step S46 to exit this routine (step S46).
When it is determined in step 1 that the read data is not normal, the process proceeds to step S54, and the process proceeds to step S36.
As in the case of (1), a predetermined error display or a warning sound is emitted, and the flow shifts to step S46 to exit from this routine while retaining the error information.

A series of processing from step S47 to step S46 serving as the determination means determines whether the memory card has been correctly mounted on the card mounting section even when the rubber connector is used in the card mounting section. It is possible to accurately determine whether or not it is not correctly mounted. If the device is not properly mounted, a predetermined error display or the like is displayed even during the processing, so that the user can quickly cope with the trouble.

Thereafter, the process proceeds to step S4 in FIG. 5, where the data stored in the semiconductor memory unit 10 of the memory card 33 is read, and the index is normally recorded in the semiconductor memory unit 10 based on the read data. That is, it is determined whether or not the format of the semiconductor memory unit 10 is normal. If an unformatted one is inserted as the semiconductor memory unit 10, it is determined that the memory format is not normal, information indicating usage conditions is input to the index unit of the semiconductor memory unit 10, and It is confirmed whether or not to perform a memory format (initialization) as a process of inputting "0" (step S5). That is, the display circuit 8 controls the drive circuit 9 to display a confirmation as to whether or not to perform the memory format.

In step S5, when the button for instructing the execution of the memory format is not pressed within a predetermined time, the driving circuit 9 is controlled to indicate that the semiconductor memory section 10 is not normal on the display 8. An error display is performed (step S8). Here, FIG.
"ERROR" is displayed, and the corresponding number is set to N to indicate the part where the error has occurred.
o. Is displayed with the characters The state at that time and the method of treatment are indicated by numbers in the middle row. At the same time, an indication that the semiconductor memory unit 10 should be replaced is displayed. Further, a switch (not shown) provided between the battery 18 for supplying power to the entire audio recording / reproducing apparatus and each circuit is turned off. Thereafter, in order to replace the semiconductor memory unit 10, it waits for the main power switch 19 to be turned off (step S9). When it is detected that the main power switch 19 is turned off, the relay switch 25 is turned off (step S9). S22), and return to step S2.

On the other hand, when it is determined in step S4 that the memory format is normal, or in step S6
After the formatting process is completed, the process proceeds to step 7 to display the completion of the initial setting, and then the semiconductor memory unit 10
The current operation position is detected based on the information read from the index section (step S10). Thereafter, each circuit is set in a waiting state while detecting whether any of the operation buttons of the audio recording / reproducing apparatus is pressed (step S11).

When it is detected in step S11 that any of the operation buttons has been pressed, it is first detected whether or not the operated button is the record button REC (step S12). For example, DSP
5 to compress the audio information input from the A / D converter 4 and control the memory control circuit 7 to control the semiconductor memory unit 1
The recording process for recording in the audio data portion of 0 is started (step S13).

If the operated button is not the record button REC, the play button PL is detected next (step S14). Here, if the play button PL is pressed, the memory control circuit 7 is controlled to
0, read out the recorded data from the audio data part, send the data to the DSP 5 and perform decompression processing, and then enter a reproduction processing for transmitting audio information to the D / A converter 11 (step S).
15).

If the play button PL has not been pressed, it is detected whether the fast forward button FF has been pressed (step S16). If the fast-forward button FF is pressed, a fast-forward process is performed in which the operation position is sequentially fast-forwarded at an appropriate speed, for example, 20 times the speed of reproduction (step S17). If the fast-forward button FF has not been pressed, it is detected whether or not the fast-return button REW has been pressed (step S18). If the fast-return button REW has been pressed, a fast-return process for moving the operating position at the same speed as in the fast-forward operation starts (step S19).

Steps S13, S15, S17, S
When the stop button ST is pressed in each of the processes 19, the process exits from each process and returns to the step S11. If the operated buttons are not operation buttons for recording, reproduction, fast forward, fast rewind, etc., the main power switch 19 is turned off or the state of various setting buttons is detected (step S20). In step S20, when the power of the main power switch 19 is turned off, the information in the index section of the semiconductor memory section 10 is updated by controlling the memory control circuit 7.
The index information stored in the storage unit (not shown) inside the main control circuit 6 is transferred to the index unit of the semiconductor memory unit 10 (Step S21). When the index transfer process is completed, the entirety of the audio recording / reproducing apparatus, that is, the relay switch 25 that supplies power to each circuit is turned off (step S22).

If it is determined in step S20 that the main power switch 19 is not turned off, the process returns to step S11. According to the above-described embodiment, it is possible to reduce a determination error as to whether or not the memory card 33 is properly mounted on the card mounting portion of the apparatus main body.
