Abstract

PURPOSE:To facilitate operator's handling by providing the center of rotation of a lock claw for engagement between an operation surface for unlocking and an operation surface for rotating a liquid crystal display device. CONSTITUTION:When the resetting operation surface 12b of the lock claw 12 for engagement is pressed, the lock claw 12 for engagement rotates around a lock pin 13 and the engagement part 12a of the lock claw 12 for engagement is disengaged from the recessed part 2a of a main body controller. Further, the engagement part 12a of the lock claw 12 for engagement leaves the main body controller 2 and then the opening/closing operation surface 12c which enables the liquid crystal display device 3 to be opened is formed. While the engagement part 12a of the lock claw 12 for engagement is unlocked, the opening/closing operation surface 12c of the lock claw 12 for the liquid crystal display device 2 is pressed down and then the liquid crystal display device 3 can be rotated. Consequently, the operator's handling is facilitated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing device, and more particularly, to a document editing device including a main body control device and a liquid crystal display device, wherein the liquid crystal display device can be opened and closed by an easy operation. .

[0002]

2. Description of the Related Art A document editing apparatus, that is, a Japanese word processor (hereinafter referred to as WP) has been remarkably popularized and is used in various offices. Further, in the personal field, a laptop type WP composed of a main body control device, a liquid crystal display device and a printing device is excellent in portability and storability and occupies the mainstream of the personal field.

FIG. 1 is an external view of the conventional document editing apparatus. The document editing apparatus of the above-mentioned conventional example is provided with a handle 1 at the front of the apparatus so as to improve the portability of the apparatus, and can be carried like a handbag. Also, FIG.
As described above, when the document editing device is used, the liquid crystal display device 3 housed in the main body control device 2 can be rotated to maintain the optimum viewing angle of the operator.

The above-mentioned prior art differs in the form of operating and using the WP and of carrying it. In particular, in order to improve the holding property of the liquid crystal display device when it is portable, it is necessary to fix the liquid crystal display device to the main body control device. Therefore, when using the WP operation, it is necessary to unlock the liquid crystal display device and rotate and hold the liquid crystal display device at an arbitrary angle.

FIG. 3 shows a conventional technique of a liquid crystal display device locking system. Main body control device 2 Recessed portion 2 at the tip
A lock claw 5 provided so as to correspond to a is composed of a lock pin 6 and a lock spring 7 at the center of the upper portion of the liquid crystal display device 3. Further, the lock claws 5 are attached directly to the LCD case 3a by the elasticity of the LCD case 3a.
Some are configured to move. When the liquid crystal display device 3 is housed in the main body control device 2, the locking lock claw 5 is locked in the recess 2a of the main body control device 2 by the reaction force of the lock spring 7, and the liquid crystal display device 3 is held in the main body control device 2. It is fixed to the control device 2.

FIG. 4 shows an operation diagram for releasing the lock of the above-mentioned conventional liquid crystal display device. The liquid crystal display device 3 is opened and freely rotated by rotating the lock claw 5. .

[0007]

In the above-mentioned prior art, the operability of unlocking and holding the liquid crystal display device at the proper viewing angle position is not sufficiently taken into consideration, and the lock claw is small and the operability is poor. Also, it was necessary to release the lock claws with both hands. Further, as a measure for improving the operability of the above-mentioned conventional example, a pop-up mechanism is provided in a hinge brake that holds the liquid crystal display device at an appropriate angle, and by removing the lock tab, the liquid crystal display device is rotated to the extent that a finger is inserted from the main body control device. However, there has been a problem that the hinge brake becomes large and the cost becomes high.

An object of the present invention is to easily open and close the liquid crystal display device in the operation of unlocking the liquid crystal display device and holding the liquid crystal display device at an arbitrary angle during WP operation. The present invention relates to a document editing device that enables operations.

[0009]

The object of the present invention is to provide a locking lock claw corresponding to the recessed portion of the main body control device at the front end thereof with a lock pin and a lock spring at the front end of the liquid crystal display device. Is provided between the locking claw portion and the unlocking operation surface.

[0010]

[Operation] When the liquid crystal display device is stored in the main body control device,
The locking portion of the lock claw formed at the tip of the liquid crystal display device is configured to fix the main body control device and the liquid crystal display device with a lock spring. When releasing the lock claw from the above state, the lock claw engaging portion is released from the main body control device by pressing the unlocking operation surface of the upper surface of the liquid crystal display device of the lock claw, and it is necessary to open the liquid crystal display device. A handle portion is formed.
