2. Description of the Related Art Conventionally, as is well known, there has been proposed or put into practical use a device capable of storing a display in a dashboard of an automobile and installing the display in a posture that can be viewed in a vehicle interior. This in-vehicle display device is
It is composed of a housing built in the dashboard, a slide rail that can be moved in and out of the housing, a display rotatably mounted on the slide rail, and the like. When the display is stored, the display surface is downwardly and horizontally stored in the housing in parallel with the slide rail, and by operating an open button, the slide rail is moved forward by a driving force of a motor. After that, the gear member provided on the lower side surface of the display is driven to rotate by another motor and rises to a posture that can be seen, and automatically stops at a predetermined angle.

[0003] In-vehicle equipment is generally not allowed to occupy a large space. In particular, such a device intended to be housed in a dashboard drives and stops the rotation of the gear member by causing the display to start up in a limited space of the DIN standard, that is, The setting of the rising angle uses the teeth of the gear cut into the gear member, which is one of the mechanical parts for rising, as it is, and detects the movement of the teeth by a photo sensor,
This is done by counting.

FIG. 4 shows the above-described gear member. Gear teeth 23 for transmitting a rotational driving force from a motor (not shown) to rotate and display the display are provided on the periphery of the gear member 22. In this example, it is cut at 5 ° intervals. Reference numeral 21 denotes a photosensor which detects and counts the movement of the teeth of the gear member accompanying the rising operation of the display, and stops the motor when a predetermined count is reached by control means (not shown) to fix the display.

[0005]

In this case, if vibration, impact, or the like is applied during the start-up operation, the teeth of the gear member are shaken due to the weight of the display portion, and the like.
The photo sensor may incorrectly count pulses. This is relatively likely to occur because this device is mounted on a vehicle. In such a case, as shown in FIG. 5A, (1), (2), (3) , (4)
The rising and falling edges of the output waveform of the photosensor should count one edge twice, and as shown in FIG. 5B, (1), (2), (2 ′),
(3) and (4), the preset normal angle does not rise, and the locking means provided at the normal angle portion is not locked. The present invention has been devised to improve such a drawback and to devise a display monitor starting angle setting device which has no problem with respect to vibration and impact.

[0006]

According to a first aspect of the present invention, there is provided a display having a rotatably supported side surface, a driving force transmitted from a motor to the display to rotate the display and a peripheral edge thereof. A gear member having a range of teeth missing from the tooth at the zero reference horizontal position corresponding to the minimum rising angle from the tooth at the zero reference horizontal position; storage means capable of storing a display angle corresponding to the tooth of the gear member; Setting means for setting a display angle to be stored in storage means; detecting means for optically detecting teeth of the gear member and outputting a predetermined signal; and setting the display to the angle based on a predetermined signal from the detecting means. This is achieved by providing fixing means for fixing the display angle set by the setting means. According to a second aspect of the present invention, in the vehicle-mounted display device according to the first aspect, when the gear member rotates, the output of the detecting means is kept for a predetermined time after the tooth at the zero reference horizontal position of the display has passed the detecting means. This is achieved by adopting a configuration that does not utilize the.

[0007]

The driving force from the motor is transmitted to the display whose side is rotatably supported so as to be rotatable, and the display is rotated at the same time as the absence of the peripheral teeth from the tooth at the zero reference horizontal position of the display. A gear member having a range of teeth corresponding to the raising angle is provided, and a display angle arbitrarily set corresponding to the teeth of the gear member is stored in the storage means,
The detection means optically detects the teeth of the gear member and outputs a predetermined signal. Based on the predetermined signal, the display is fixed at the angle stored in the storage means. Angle can be set. In addition, during the rotation of the gear member, the output of the detection means is not used for a certain time after the tooth at the zero reference horizontal position of the display has passed the detection means, so that the vibration or impact at the time of the rising or falling operation of the display is prevented. Alternatively, it is possible to prevent erroneous operation due to catching of the mechanism.
