Description

Locking Apparatus of Charge Coupled Device Module

The present invention relates to a lock of a charge coupled device module applied to a product that implements a scan function, and more particularly, to a lock of a charge coupled device module configured to automatically operate the lock of the charge coupled device module. Relates to a device.

A Charge Coupled Device is a type of semiconductor memory device that performs a function of storing and transferring information in the form of charge by arranging a plurality of micro metal electrodes on a silicon wafer.

These memory devices are applied to computers, printers, copiers, scanners, and facsimiles used in homes or offices.

However, the above-described memory device has a high risk of being damaged when an external shock is applied. In the related art, as shown in FIGS. 1A and 1B, the scan frame 1 and the charge coupled device module 3 are fixed using the screw 4. Thus, when the product is shipped or moved for distribution, the charge coupling device is prevented from being damaged by the vibration of the product.

Also, as shown in FIG. 2, fixing jaws 1a and 3a are formed on the lower portion of the charge coupling device module 3 and the scan frame 1 to be fixed by walking.

However, the above-described conventional structure has a problem in that all of people have to perform screwing work by manually screwing the screw 4 or fastening the jaws 1a and 3a in order to fix the charge coupling device module. And, when using the product there is a cumbersome problem that must be used to release the lock.

In addition, there is a problem that the risk of screw loss is high, because the screw is stored in a separate storage box and used as needed.

The present invention has been made to solve the above problems, an object of the present invention is implemented to automatically lock or unlock the charge-coupled device module by the joint movement in accordance with the forward and backward operation of the charge-coupled device module. The present invention provides a locking device for a charge coupling device module that eliminates the task of locking a charge coupling device module by a person, as well as eliminating the problem that the lock device is not reused.

Locking device of the charge coupling device module according to the present invention for achieving the above object is a scan frame, a charge coupling device module installed on the upper surface of the scan frame capable of forward and backward to perform a scanning function, and the charge coupling device And a locking device for locking the charge coupling device module or releasing the locking state by performing joint motion according to the forward and backward motions of the module.

<Explanation of symbols for the main parts of the drawings>

11 scan frame 13 charge coupled device module

13a: projection 13b: locking jaw

20: locking device 21: circular bar

21a: contact protrusion 24, 25: rotation axis

27: torsion spring

Hereinafter, with reference to the accompanying drawings 3 to 6 will be described in more detail the configuration and operation of the present invention.

As shown in the drawing, there is a scan frame 11, and the scan frame 11 includes a charge coupling device module 13 that linearly moves forward or backward, and the front and rear of the charge coupling device module 13. The locking device 20 is configured to automatically lock the charge coupling device module 13 or release the locking state by performing a joint motion according to a backward motion.

The locking device 20 is a driving bar 21 is installed at a predetermined angle to rotate in contact with the projection (13a) provided on one end of the charge coupling device module 13, the driving bar 21 is a rotary motion Driven to rotate in a direction opposite to the rotational direction of the driving bar 21 so as to be inserted into the locking step 13b provided in the charge coupling device module 13 so as to be rotatable at a predetermined angle with the driving bar 21. It consists of a bar 23.

The driving bar 21 and the driven bar 23 is configured such that the torsion spring 27 is wound around the rotating shafts 24 and 25 to have a restoring force.

The latching jaw 13b is formed by “b” and is configured to insert and end the end of the driven bar 23.

Reference numeral 21a denotes a contact protrusion in contact with the protrusion 13a.

Next will be described the operation of the charge-coupled device module locking device according to the present invention configured as described above.

First, while the charge coupling device module 13 is leaving the locking device 20 and performing a scan operation as shown in FIG. 3, the locking device 20 is in an initial state, and thus, the driving bar 21 and the driven bar. 23 is positioned at a predetermined angle.

Then, when the charge coupling device module 13 stops the scanning operation, the driver reverses, and the protrusion 13a formed at the end of the charge coupling device module 13 by the reverse operation causes the contact protrusion of the driving bar 21 to be moved. The driving bar 21 in contact with the projection 21 is rotated counterclockwise about the rotation shaft 24 as it contacts 21a and continues the linear movement. At this time, the driven bar 21 and the driven bar 23 connected to allow the joint movement is interlocked to rotate clockwise about the rotating shaft 25.

In the above-described principle, when the charge coupling device module 13 moves linearly, and the driving bar 21 and the driven bar 23 continue to rotate, the driving bar 21 and the driven bar 23 are moved. While maintaining the upright state as shown in FIG. 6, the end of the driven bar 23 is inserted into the latching jaw 13b formed in the charge coupling device module 13 to close the charge coupling device module 13. It will automatically be locked.

At this time, the torsion springs 27 wound around the rotary shafts 24 and 25 of the driving bar 21 and the driven bar 23 by the support force of the protrusion 13a and the locking jaw 13b may have a predetermined torsional force. A state of operation is achieved (see Fig. 6).

In the above, the torsion springs on the rotating shaft 25 is also configured to have a spring of the same shape as the torsion springs 27 wound on the rotating shaft 24.

Then, when the charge coupling device module 13 is advanced in the opposite direction to the above-described direction for the scan operation, the driving bar 21 and the driven bar 23 is clocked by the restoring force of the torsion spring 27. It will be rotated in the direction and counterclockwise to maintain the state of FIG.

Therefore, it is possible to solve the inconvenience that a person has manually locked the device by using a screw or other locking device to directly fix the charge-coupled device module 13.

In addition, the risk of losing a lock such as a screw can be eliminated.

According to the locking device of the charge coupling device module according to the present invention as described above, by implementing the locking device that rotates in a predetermined direction in conjunction with the forward and backward operations of the charge coupling device module to ship or distribute the product When the product is transported for the purpose, by using a separate locking device to eliminate the hassle of having to manually lock the person, it is possible to eliminate the risk of losing the lock.
