Problems solved by technology

[0004] However, in the current disc changer, the lifting device has no reference positioning point, that is, the height of each layer cannot be accurately measured, and the only reference is based on the change of the voltage value of a variable resistor in the optical drive. for moving between layers
Although the firmware in each disc changer has a built-in ideal height table, when the disc changer is assembled, the actual height of these layers will be different from the built-in ideal height due to the assembly tolerance of the mechanism there will be a slight gap
When pulling the sheet, it will be impossible to pull the sheet smoothly due to these drop differences, and even cause the card

Embodiment Construction

[0028] Please refer to FIG. 1 , FIG. 2 and FIG. 3 at the same time, which are respectively a schematic top view of the lifting device of the present invention, a schematic view of the front side of the disc changer, and a schematic view of the rear side of the disc changer.

[0029] It can be seen from FIG. 1 that the lifting device 104 includes a positioning foot 102 and a linear variable resistor 106 . In this embodiment, the lifting device 104 is movably arranged in the film changer 100, and the film changer 100 can be placed into a film cassette (as shown in reference numeral 112 in FIG. 2 ). Readers can easily know that the cassette 112 can be loaded with a plurality of optical discs, and these optical discs are arranged in different layers (FIG. 2 is an example in which 10 discs can be inserted).

[0030] The front side and the rear side of the film changer 100 are respectively provided with a guide rail (as shown in the reference number 108 in FIG. 2 and the reference n...

Abstract

This invention relates to one lift device height position method, which comprises the following steps: judging whether one slice box is put into the switch machine; when it is put to the box, then lift device processes one zero computation; then accordingly, computing each layer height of the switch machine; then lift device computes height accordingly.

Description

technical field [0001] The present invention relates to a height positioning method, in particular to a height of a lifting device that repositions the relationship between the height of each layer and the voltage value of the variable resistor each time the power is turned on or after the cassette is inserted. Positioning method and film changer. Background technique [0002] With the vigorous development of computer technology, in order to store data in the computer, most of the data is converted into digital form, and in order to allow users to access data more conveniently, various computer manufacturers have successively developed A wide variety of digital data storage devices have been introduced. Among them, one of the most influential to people's lives is exactly CD-ROM and CD-ROM drive. The optical drive makes full use of the characteristics of low cost, small size and large capacity of the optical disc, and burns digital data on the optical disc, which is not onl...
