Abstract

PURPOSE:To adjust a plane display part to an optimum position with good operability by detecting the arrangement angle of the variably set plane display part to automatically initially arrange the plane display part based on arrangement angle information which is stored while being updated. CONSTITUTION:When move direction indication is prompted by a specific key on a keyboard 1, a motor driving circuit 4 rotates forward/backward or starts/ stops a DC motor in accordance with the indication of a CPU 2 to variably set the arrangement angle of a plane display device 9. At such a time, a timer circuit 8 and the CPU 2 constituting a detecting means detect the arrangement angle of the variably set plane display device 9, and arrangement angle information is stored in a RAM 6 while being updated. When a power source 10 is turned on, the CPU 2 controls driving of the DC motor 5 based on this arrangement angle information to automatically initially arrange the plane display device 9, and the plane display device 9 is automatically positioned to an angular position corresponding to the latest arrangement angle information. Thus, the plane display device 9 is automatically arranged in the angular position most suitable for a user.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic device equipped with a movable mechanism that moves a flat display section and places it at a desired position.

[Conventional technology]

With recent advances in electronic technology, computer devices have become smaller and lighter and smaller, ranging from desktop types to portable laptop types.

This is due to the commercialization of various flat display devices, such as plasma displays, liquid crystal displays, and backlight type liquid crystal displays, in place of the high-resolution CRT displays used in conventional display devices. However, it is large.

The position and angle of such a display device changes depending on whether it is normally stored in a computer device or when it is used, ensuring ease of viewing from the user's viewing angle and the reflection of indoor light. Therefore, in many cases, an adjustment mechanism is provided to make adjustments to satisfy various conditions.

Also, attempts are being made to move the flat display by transmitting electric power to the adjustment mechanism.

[Problem to be solved by the invention]

However, since the flat display is arranged in different positions when it is used and when it is stored, the flat display must be adjusted every time it is used, which is extremely troublesome.

Further, the above-mentioned angle during use depends on the body shape and posture of the user, and there have been problems such as the optimum initial setting angle for a flat display cannot be uniquely determined.

This invention was made to solve the above problems, and by detecting and storing the arrangement angle of the flat display set by the user, the flat display can be set at the optimal angle for the user when the power is turned on. The purpose is to obtain an electronic device that can be automatically placed at a certain position.

(Means for Solving the Problems) An electronic device according to the present invention includes an electric motor that transmits electric power to a movable mechanism, an indicating means for instructing a movable direction of a flat display section, and a movable direction that is determined by the indicating means. a variable means for variably setting the arrangement angle of the flat display section by controlling forward/reverse rotation of the electric motor based on a specification; a detection means for detecting the arrangement angle of the flat display section variably set by the variable means; A storage means that updates and stores arbitrary arrangement angle information detected by the detection means, and automatically controls the flat display section by controlling the drive of the electric motor based on the arrangement angle information stored in the storage means each time the power is turned on. A placement control means for initial placement is provided.

Further, the movable direction instruction by the instruction means is configured to be performed by simultaneously pressing a plurality of specific keys on the keyboard.

[Effect]

In this invention, when the movable direction is designated by the instruction means, the variable means controls forward/reverse rotation of the electric motor and variably sets the arrangement angle of the flat display section. At this time, the detection means detects the variably set arrangement angle of the flat display section, and arbitrary arrangement angle information indicating the detected stop angle position is updated and stored in the storage means. Then, when the power is turned on, the arrangement control means controls the drive of the electric motor based on the arrangement angle information stored in the storage means to automatically initialize the flat display section and correspond to the latest arrangement angle information. Position the flat display section at an angular position.

Further, by simultaneously pressing a plurality of specific keys on the keyboard, the movable direction is instructed and the variable means is prompted to move the flat display section.

(Embodiment) FIG. 1 is a block diagram illustrating the configuration of an electronic device showing an embodiment of the present invention. Reference numeral 1 denotes a keyboard (KBD) which also serves as an instruction means of the present invention to input commands, data, etc. to the CPU 2. In addition to manual input, the variable setting instructions for the plasma-type flat display 9 capable of displaying four gradations can be given by pressing keys arranged on the keyboard 1, such as a combination of multiple numeric keys ("1" key, "2" key, The "3" or "1" key, the "2" key, and the key "4" are used to instruct the movable direction of the flat display 9 in the direction a or direction b shown in FIG. 2(b).

The CPU 2 comprehensively controls each device connected to the CPU bus 11 based on a control program stored in the ROM 3 (including each black ratio in the flowcharts shown in FIGS. 3 to 5, which will be described later). 4 is a motor drive circuit, CPU
2 outputs a rotation control signal to the DC motor 5 to rotate the DC motor 5 forward/reversely and stop it according to instructions.

Reference numeral 6 denotes a RAM which also serves as a storage means of the present invention, and is backed up by a battery 7 and stores information in a predetermined area, ie, information on the arrangement angle with respect to the flat display 9, etc. in an updatable manner. Note that the RAM 6 functions as a work area for the CPU 2 and stores flag information under the control of the CPU 2 when processing the ROM 3 or user programs. 8
is a timer circuit, which is started and stopped by the program (BiO2) in ROM3, and is activated and stopped by the program (BiO2) in ROM3.

2” key, key “4”), for example, 500m.
5, and the measured time is determined by the movement direction value (for example, if the flat display 9 moves in the a direction, it is a ten value, and if the flat display 9 moves in the b direction, it is a one value). (as the value) is updated in RAM6 (within a 2-byte storage area).

In this way, when a movable direction instruction is prompted by simultaneous pressing of a plurality of specific keys on the keyboard 1 constituting the instruction means, the 8-bit register, for example, is Assigned on the address bus of P U 2, ROM 3 transfers 4 to that address.
By writing the correct bit pattern, the motor drive circuit 4 causes the DC motor 5 to rotate forward/reverse, start/stop, and variably set the arrangement angle of the flat display 9.

At this time, the timer circuit 8 and the CPU 2 constituting the detection means
detects the variably set arrangement angle of the flat display 9, and arbitrary arrangement angle information (count value in this embodiment) indicating the detected stop angle position is stored in the RAM 6 while being updated. Then, when the power source 10 is turned on, the CPU 2 controls the drive of the DC motor 5 based on the arrangement angle information stored in the RAM 6 to automatically initialize the flat display 9, and adjusts it to the angle corresponding to the latest arrangement angle information. The flat display 9 is automatically positioned at the position, and 8 lines of normal BOOT processing are performed.

Note that if the storage area of the arrangement angle information stored in the RAM 6 is slightly expanded to enable multiple users to be registered, the flat display 9 can be moved to the optimal angular position for multiple operators by the above key operations and selection instructions. Needless to say, automatic positioning is possible.
