BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drive unit for an on-vehicle tape deck unit, and more particularly, the present invention detects a current use mode of a current tape from a predetermined tape use mode and requests it from the outside. The present invention relates to a drive device for a tape deck unit that smoothly shifts to a mode.

[0002]

2. Description of the Related Art FIG. 8 is a diagram showing a conventional drive device for a tape deck unit. As shown in the figure, the tape deck drive has a use mode, that is, a play mode in the leftward and rightward directions (PLAY-L, PLAY-R),
A header drive unit 1 that sets a fast-forward mode (FF), a rewind mode (REW), and a stop mode (STOP);
A mode detection unit 2 that works together with the header drive unit 1 to detect the usage mode of the header drive unit 1, a motor 3 that drives the head drive unit 1 and the mode detection unit 2, and a mode detection unit 2
A photosensor 4 and a switch 5 which are attached to the vehicle and detect a use mode; and a control unit 6 which inputs information of the photosensor 4 and the switch 5 and stores the information in a memory 7 to control the motor in a request mode from the outside. It is provided.

FIG. 9 is a diagram showing the mode detector 2 of FIG. As shown in the figure, the mode detector 2 includes a lever 2-
The lever 2-0 is provided with a plurality of slits 2-1, 2-2, 2-3, 2-4, 2-5 in the positive direction. The photo sensor 4 has a light emitting unit 4-1 for detecting the presence or absence of a slit by the passage of light, and a light receiving unit 4-2. The photo sensor 4 outputs an “L (low)” signal when it comes to the position of each slit, and otherwise outputs “H (hi)”.
gh) ”signal is output. The switch 5 has a spring structure to electrically open and close by pressing the lower end of the lever 2-0. When the switch 5 is pressed, it outputs an “L” signal, and when the pressing is released, it outputs an “H” signal.

FIG. 10 is a diagram showing output waveforms of the photosensor 4 and the switch 5 of FIG. 8, and FIG. 11 is a diagram showing an example of ejecting the tape from the tape deck. . As shown in FIG. 11, when the tape 7 is ejected from the tape deck 8, as shown in FIG. 10A, the switch 5 is pressed and the "L" signal is output to form the ejection mode. On the contrary, when the "H" signal is output, the insertion mode in which the tape 7 is inserted in the tape deck 8 is formed.

Further, as shown in FIG. 10B, when the photo sensor 4 is at the position of the slit 2-1, it indicates that the header drive unit 1 is in the stop mode, and similarly, the position of the slit 2-2 is shown. Indicates that you are in rewind mode,
The slit 2-3 position indicates the fast winding mode, the slit 2-4 position indicates the leftward play mode, and the slit 2-5 position indicates the rightward play mode. It is shown in.

Since the control mode is thus clear in advance based on the position of the slit, the control unit 6 drives the motor 3 to shift from the slit position of the current use mode to the slit position of the required use mode. Is possible.

[0007]

By the way, in the drive unit for the tape deck unit, when the power is turned on while the tape is inserted in the tape deck, or when the tape deck unit is reset in case of abnormality, the control unit 6 is used. Since the memory 7 does not store the slit position of the current use mode, it cannot be determined. Therefore, as shown in FIG.
For the time being, eject the tape to make it eject complete,
Established initial position for transition.

In this case, however, it is necessary to eject the tape due to the convenience of the tape deck even though the bent tape has been inserted into the tape deck, and also to bother in the insertion mode by the user's insertion operation, which is wasteful. It takes a long time. Further, not only during use, but also during manufacturing, when the tape deck unit is first mounted in a vehicle for mounting on a vehicle, a tape discharging operation similarly occurs, which complicates the process.

FIG. 12 is a diagram showing another example of ejecting a tape from a tape deck. As shown in this figure (a), there is a tape deck 8 having a liquid crystal display screen 9 in front of it. In this case, when the tape deck 8 is in the ejection mode, the liquid crystal display screen 9 slides sideways as shown in FIG. 6B, and the tape 7 is ejected. Therefore, it is necessary for the user to insert the tape 7 and restore the display screen 9 to its original state. There is a problem in that it is complicated to move the liquid crystal screen 9 every time the tape deck 8 is reset due to an abnormality or the like. Instead of the liquid crystal screen 9, it may be a huge door or an operation panel.

Therefore, in view of the above problems, the present invention can shift to another usage mode without ejecting the tape from the tape deck when the power is turned on when the tape is inserted in the tape deck. An object is to provide a drive device for a tape deck unit.

[0011]

In order to solve the above problems, the present invention provides a drive device for a tape deck unit having the following structure. That is, a tape deck unit drive device in which a tape is inserted into a tape deck in order to make a transition between a plurality of use modes of the tape has a plurality of slits corresponding to the use mode, and whether or not these slits are present. A first lever detected by the first photo sensor is provided.

Is detected by the photo sensor of. The control unit moves the first lever and the second lever when the power is turned on or reset, and the second lever is moved.
The slit position of the first lever is determined based on the output level of the photo sensor of.

[0012] A series of slits corresponding to a part of the above-mentioned use modes are provided in a drive unit of a tape deck unit in which the tape is inserted in a tape deck in order to shift the use modes of the tape, and the plurality of slits. Having a notch at a certain distance and the presence or absence of these slits,
A third lever is provided in which the presence or absence of the cutout portion is detected by the first photo sensor. The fourth lever has a series of a plurality of slits for interlocking with the first lever for performing the remaining transition of the use mode, and a cutout portion following these slits. The presence or absence of the copy is detected by the second photo sensor.
The control unit moves the fourth lever and the fourth lever at the time of power-on or reset, and based on the output levels of the first photo sensor and the second photo sensor, the control unit controls the third lever and the fourth lever. Determine the slit position.

The third lever may have a series of slits corresponding to a part of the use mode, and the presence or absence of these slits may be detected by the first photosensor. The control unit may set the tape in the play mode after the slit position is determined at the time of power-on or reset.

[0014]

According to the drive device for a tape deck unit of the present invention, the first lever and the second lever are moved when the power is turned on or reset, and the output level of the second photosensor changes, and this change is detected. Based on this, the slit position of the first lever is determined. Therefore, when the power is turned on, the position of the tape can be determined without ejecting the tape, and the tape will not be ejected even when the power is turned on with the tape inside. Even if there is a liquid crystal display screen or operation panel, it is not necessary to open it in advance.

Further, at power-on or reset, the fourth
And the fourth lever are moved, the output levels of the first photosensor and the second photosensor are both set to "L", and the slit positions of the third lever and the fourth lever are set in the same manner as described above. It can be confirmed without ejecting the tape. The third lever has a series of a plurality of slits corresponding to a part of the use mode, and the presence or absence of these slits is detected by the first photosensor, whereby the third lever and the fourth lever are provided. The slit position of the lever can be determined without completing the ejection of the tape as described above.

The control section automatically switches to the play mode when the power is turned on or reset by setting the tape in the play mode after fixing the slit position when the power is turned on or when the power is reset. Audio output is possible in a short time.

By detecting at the same time, the positions of the slits of the levers 300-0 and 400-0 can be determined. Therefore, when the power is turned on, the position of the tape can be determined without ejecting the tape, and the tape will not be ejected even when the power is turned on with the tape inside. Even if there is a liquid crystal display screen or operation panel, it is not necessary to open it in advance.

FIG. 6 is a diagram showing a modification of the mode detection unit 200 of FIG. As shown on the left side of the figure, there is no fixed position cutout 300-4 in FIG. FIG. 7 is a diagram showing output waveforms of the photosensors 4, 101 and the switch 5 of FIG. As shown in the figure, when the tape is inserted and the photo sensor 4 passes through the slit positions in the stop mode, the rewind mode, and the fast-forward mode, the photo sensor 4 outputs the "H" signal from that point.

Therefore, according to this embodiment, the operation of the control section 6 differs as follows depending on the level of the output signal of the photo sensor 101 when the power is turned on. Photo sensor 10
When the output signal of 1 is "H", the tape is moved in the inserting direction until the output signal of the photosensor 101 becomes "L". When this "L" is detected, the tape is moved in the ejection direction until the output signal of the photo sensor 4 becomes "L".
By detecting this "L", the slit position in the fast-forward mode is determined.

When the output signal of the photo sensor 101 is "L", the tape is moved in the ejecting direction until the output signal of the photo sensor 4 becomes "L". By detecting this "L", the slit position in the fast-forward mode is determined. Therefore, when the power is turned on, the position of the tape can be determined without ejecting the tape, and even if the power is turned on with the tape still inside, the tape will not be ejected. Even if there is a liquid crystal display screen or operation panel, it is not necessary to open it in advance.

Further, the controller 6 determines the tape position as described above, and then moves the slit in the target play direction to bring the slit into the play state. For this reason, when the power is turned on while the tape is still in the tape deck, it automatically plays immediately, so the user does not need to do anything.
Audio output is possible in a short time.

[0028]

As described above, according to the present invention, when the power is turned on or reset, the first lever and the second lever are moved, and the output level of the second photosensor is changed. Based on this, the slit position of the first lever is determined. Therefore, when the power is turned on, the position of the tape can be determined without ejecting the tape, and the tape will not be ejected even when the power is turned on with the tape inside. Even if there is a liquid crystal display screen or operation panel, it is not necessary to open it in advance. Further, when the power is turned on or reset, the fourth lever and the fourth lever are moved so that the output levels of the first photosensor and the second photosensor are both “L”, and the third lever and the fourth lever are output. The slit position of the lever can be determined without the completion of ejecting the tape. The third lever has a series of a plurality of slits corresponding to a part of the use mode, and the presence or absence of these slits is detected by the first photosensor, so that the third lever and the fourth lever are provided. The slit position can be determined without completing the tape ejection as described above. Since the tape is placed in the play mode after the slit position is fixed at power-on or reset,
Since the play mode is automatically set, the user's operation is not required and the voice output can be performed in a short time.
