The accommodating portion 5 of the monitor 3 is disposed on a car audio device 6, and a disc insertion slot 2 is provided on a front panel 1 of the car audio device 6 so as to extend in a horizontal direction.

[0003] The monitor 3 is rotatably supported by a slider 4 which can be moved into and out of the accommodating section 5. After the monitor 3 is pulled out from the accommodating section 5 together with the slider 4, the monitor 3 is pivoted upward.

[0004]

In the above-mentioned conventional in-vehicle housing type monitor, when the monitor 3 is pulled out of the housing portion 5 as shown in FIG.
The disc insertion slot 2 is hidden by the monitor 3 and hard to see,
The operability of taking the disk 7 in and out was poor, and there was a risk that the disk 7 could be damaged by being dropped. In addition, the front panel 1 of the car audio device 6 is
There was also a risk of injuring. If the head is lowered to the position where the disk insertion slot 2 can be seen and the disk 7 is inserted, the disk 7 can be inserted reliably, but the head cannot be lowered during operation.

The monitor 3 can be housed in the housing portion 5 by key operation to insert and eject the disk 7. However, it takes time to insert and remove the disk 7, and the monitor is not operated while the disk 7 is being inserted or ejected. There was a problem that it could not be used.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to insert and remove a disc when a housed monitor such as a vehicle-mounted television is placed on a car audio device. It is an object of the present invention to provide an in-vehicle accommodation type monitor which can be operated in a short time with good operability and can be used even when a disc is inserted and ejected.

[0007]

According to the present invention, there is provided an on-vehicle housing monitor which is driven between a housing position housed in a box-shaped housing portion and a use position outside the housing portion. By operating a key arranged outside the accommodation unit or a sensor arranged outside the accommodation unit detects the proximity of a hand, a monitor screen can be seen from an occupant other than the use position and the accommodation position. The recording medium is driven to a retracted position where the recording medium can be inserted and removed from a recording medium insertion port located below the storage section.

[0008] In the above-mentioned housing type monitor,
The electronic device is configured to be driven from the retracted position to the use position by detecting the entry / exit of the recording medium of the in-vehicle electronic device disposed below the in-vehicle housing type monitor or by key operation.

Further, in each of the on-vehicle housing-type monitors, the retracted position is stored in a memory, and the monitor is driven to the retracted position stored in the memory.

[0010] In the above configuration, the evacuation position of the monitor is set to a position that does not hide the disk insertion port or the like of the car audio device arranged below the monitor, so that the disk can be easily inserted and removed, and the monitor can be stored in the storage position. The monitor can be moved in a shorter time than moving the monitor. As a result, it is possible to move the disk in and out in a short time. When the monitor is retracted to an arbitrary position stored in the memory, the evacuation position can be set to an optimal position corresponding to the vehicle type or the arrangement of the monitor.

Reference numerals 2 and 12 are engaged with racks 13 and 13 fixed to the storage section. The slider 4 is driven in the front-rear direction by the rotation of the motor 10.

The retracted position of the slider 4, that is, the position of the slider 4 that has moved to the back of the housing is detected by a microswitch 14 fixed to the housing. The photo sensor 15 fixed to the slider 4 detects the number of rotations of the gear train and outputs a pulse signal. The slider position detection counter of the control unit (not shown) is reset when the micro switch 14 is turned on, and recognizes the position of the slider 4 by counting the pulses of the photo sensor 15.

The slider 4 rotatably supports the monitor 3 via shafts 4a, 4a. A motor 16 fixed to the slider 4 rotates a gear 19 rotatably supported by the slider 4 via a gear train. The gear 19 meshes with a partial gear 3b provided on the monitor 3. The monitor 3 is rotated around the shafts 4a and 4a by the rotation of the motor 16.
The horizontal position of the monitor 3 is detected when the projection 3a provided on the monitor 3 operates the microswitch 17 fixed to the slider 4. The photo sensor 18 fixed to the slider 4 detects the number of rotations of the gear train and outputs a pulse signal. The monitor rotation position detection counter of the control unit is reset when the micro switch 17 is turned on, and recognizes the rotation position of the monitor 3 by counting the pulses of the photo sensor 18.

FIG. 2 shows the use state of the above-mentioned on-board monitor. The accommodating portion 5 of the monitor 3 is disposed on a car audio device 6, and a disc insertion slot 2 is provided on a front panel 1 of the car audio device 6 so as to extend in a horizontal direction. When the open / close key 3c is pressed while the monitor 3 is housed in the housing 5, the slider 4 projects from the housing 5 together with the monitor 3, and the monitor 3 is shown in FIG. 2 (a) or 2 (b). It is rotated to the use position. When the open / close key 3c is pressed at the use position, the monitor 3 is driven to the storage position.

The protrusion position of the slider 4 and the rotation position of the monitor 3 are set in a slider position detection counter and a monitor rotation position detection counter of a control unit (not shown), respectively. This setting may be set at the time of shipment, or may be set by a user.
