Abstract

A slide type mobile terminal for recognizing its sliding up and down is provided to accurately recognize a slide ON/OFF state without using a magnet or a magnetic sensor. A sliding movement transfer unit includes a carrier(200) which can be moved by being tightly attached on both sides of a linear groove formed in a sliding direction and a stopper formed at one side of the groove. A pivoting movement unit(300) is provided on a lower panel(400) and combined with the carrier(200) so that a pivoting movement bar(350) is downwardly pivoted by a hinge part according to a horizontal movement of the carrier(200) to allow an upper contact part(351) to contact with a lower contact part(352). When the carrier(200) is moved in the opposite direction to the direction of the horizontal movement, a hinge tension spring(370) restores the pivoting movement unit(300) so that the carrier(200) can be released from the pivoting movement unit(300) and the upper and lower contact parts(351,352) can be detached. A sensor(500) senses the contact of the pivoting movement unit(300).

The present invention relates to a slide type open / close recognition mobile communication terminal, and more particularly, to a mechanical open / close recognition mobile communication terminal capable of accurately recognizing a slide on / off state without using a magnet and a magnetic sensor.

The term "mobile communication terminal" of a conventional concept refers to an electronic device that a user can carry out wireless communication with a counterpart while carrying. Such portable communication devices are becoming smaller, slim, grip, and lighter in consideration of portability, and are moving toward a multi-media direction that can pursue various functions. In particular, more and more portable terminals will be used for miniaturization, light weight, multifunction, and versatility, and are being modified to adapt to various multimedia environments and the Internet environment. In addition, the portable terminal is an electronic device commonly used anywhere in the world, men and women, and is being recognized as a necessity to carry around at all times.

Mobile communication terminals can be generally classified into a flip-type, a folder-type, and a sliding-type according to their appearance or operation.

Among them, the sliding type mobile communication terminal overlaps the two sliding parts and takes a method of directing the display unit and the keypad in the same direction to each sliding part. In general, the sliding terminal may expose the main body on the rear side by sliding the front sliding part cover. Typically, a keypad and a microphone are disposed in the main body, and a display unit and a speaker are disposed on the cover.

In the case of the sliding type mobile communication terminal, the cover is pushed upward on the lower main body and is in a slide-on state in a call or operating mode, and the cover is lowered in the slide on state on the lower main body. The standby mode is a slide-off state in which the cover is completely lowered along the lower body so that the cover is completely hidden.

In the case of the sliding type mobile communication terminal, a detection system for detecting an operation mode or a standby mode is mounted inside the terminal, and when the operation mode is activated, power is supplied to the display unit, keys, etc. of the terminal, and the cover slides downward from the lower body. When the display is turned off and in the standby mode, the power of the display unit, the key, and the like blink.

The detection system of a conventional slide type mobile communication terminal is composed of a magnet mounted on a cover and a sensor for detecting the magnetic property of the magnetic on a main body, for example, MR, Hall IC. This sensor is used to detect the strength of the magnetic force as the cover moves, and detects the slide on and off states.

This approach can also cause the sensor to operate even if the cover is slightly opened or closed. In particular, even when the cover is only slightly moved in the slide-off direction, that is, the closing direction, the sensor malfunctions and the sensor recognizes the standby mode, that is, the slide-off state. The power supply of the operating part will blink.

In addition, a magnetic object is often used among articles carried by an individual, and a magnetic object is used in many devices in real life. Therefore, the frequency at which terminals are exposed to such magnetic objects becomes very high. In the case of a conventional terminal using a magnet and a magnetic sensor, when a strong magnetic object approaches the sensor, it is correlated with the actual slide on and off states. There is a problem that causes a malfunction.

The present invention has been invented to solve such a problem, and keeps the slide-on state until the cover is slid from the main body to reach the slide-off state so that the terminal state can be recognized as the slide-on state. An object of the present invention is to provide a slide type open / close recognition mobile communication terminal.
