Abstract

PURPOSE:To shorten the waiting time for write/read operation by using a control member which rubs a single side of a card put on a carrier stage and controls the tilt of the card. CONSTITUTION:A card C is moved toward an arrow head and set onto a carrier stage 8. The tip of the card C follows the tip of a control member 30 and therefore the card C is moved to a single side of the stage 8. Then the card C is pressed toward a horizontal part 20 and guided by the guide rolls 27. A limit switch detects a state where the card C is put completely on the stage 8 and starts feed mechanisms 10a and 10b. Then a feed screw 12 is revolved and a mover 14 which is screwed to the screw 12 moves over the mechanisms 10a and 10b. Thus the coupled stage 8 moves over a base 2 in response to the shift of the mover 14 and the two lengthwise sides of the card C are held between the member 30 and a vertical part 22. Then those two sides follow the member 30 is response to the shift of the stage 8 and the stage 8 reaches a write/read position 4 and hits a stopper 28. Thus the shift of the stage 8 is stopped.

Description

[Detailed Description of the Invention] [Industrial Application Field] When writing or reading data on an optical memory card, the present invention receives a card inserted by a card holder and fixes the card in a position where writing or reading is to be performed. Regarding the card holder to hold.

[Prior Art] Recently, optical memory cards have been attracting attention as a large-capacity card-type recording medium that can replace magnetic cards and IC cards.

This optical memory card records digital data using optical change patterns such as high and low reflectance. Since a light beam such as a laser beam is used for recording, data can be recorded with high density and large-capacity recording is possible.

Therefore, in order to write or read high-density recorded data without error, it is necessary to accurately position the card relative to the write/read head.

Conventionally, as a means for positioning, similar to the fixing of magnetic cards, etc., there is a method of providing parallel fixing guides along the longitudinal direction of the card and sandwiching the card between the fixing guides.

There is also a method of positioning the card by sandwiching and fixing the two longitudinal sides of the card using springs.

[Problems to be Solved by the Invention] However, the above conventional means had the following problems.

In other words, in the case of fixed guides, it is necessary to easily insert the card between the guides, so there are several holes between the guide and the card.
A certain amount of leeway has been taken. Therefore, there is a drawback that variations occur when writing data, and reading errors occur during reading, making accurate writing and reading difficult.

On the other hand, the latter method of fixing with a spring has a complicated structure, and also requires a mechanism to energize and release the spring when attaching and detaching the card. There are other problems. Furthermore, in this method, the means for conveying the card and the means for positioning the card are separate means, and in order to position the card after the conveyance is completed, the card is inserted into the writing/reading device by the user, and then the card is positioned. , it takes a long time to start writing/reading, which is not practical.

The present invention was made to solve such problems,
It has a simple structure, can be positioned accurately without any play, and it takes a long time to start writing/reading after the user inserts the card into the writing/reading holder. The purpose is to provide a practical car holder.

[Means for Solving the Problems] The present invention provides a card that receives a card inserted by a card holder when writing or reading data on an optical memory card, and that the card is fixedly held at the position where data is written or read. The holder includes a transport table that holds and holds the loaded card, transports it to a writing or reading position, and fixes it; a feeding mechanism that transports and drives the transport table; and a transport mechanism that transports and drives the card to insert the card from the writing or reading position. The present invention is characterized in that it includes regulating members that are arranged opposite each other at the positions where the card is removed and come into sliding contact with one side of the card placed on the carrier table A to regulate the inclination of the card.

[Function] In the present invention, a card to be written or read is transported from a mounting position to a writing/reading position by a transport table driven by a transport mechanism. Since a regulating member is provided that makes sliding contact with one side of the card and regulates the inclination of the card, the card placed on the carrier will have its lower side come into sliding contact with the regulating plate as the carrier moves. Become. Therefore, while the card is being transported from the position where the card is inserted or removed to the position where it is written or read, the card follows the regulating member and is accurately positioned when it reaches the position where it is written or read. .

Therefore, it has a simple structure, allows accurate positioning without any play, and takes a short time from when the user attaches the card to the writing/reading device to when writing/reading starts. It doesn't cost.

[Example] Embodiments of the present invention will be described with reference to the drawings.

<Configuration of Embodiment> FIGS. 1 and 2 show an embodiment of the card holder of the present invention.

The card holder shown in these figures is installed on a base 2 on which a write/read position 4 and a card mounting position 6 are set.
Transport table 8, feeding mechanisms 10a, 10b, and regulating member 30
It is composed of:

The conveyor table 8 is formed to have a concave cross-section and includes a horizontal portion 20 and a vertical portion 22, and a groove 24 is formed in a portion of the horizontal portion 20 closer to one of the vertical portions 22.

Additionally, two wooden guide rollers 26 are provided between the vertical parts 22 and 22.

The feed mechanisms 10a and 10b are each configured identically, are supported by bearings 16.18, and are screwed into the feed screw 12 rotated by a rotational drive device (not shown). The moving element 14 is connected and fixed to the vertical part 22.

The regulating member 30 has one end fixed to the carrier stopper 28,
It is provided floating on the base 2 in the form of a cantilever beam. and,
The non-fixed end side is in the groove 24 of the horizontal part 20 of the conveyance table 8,
It is inserted along the longitudinal direction. This regulating member 30 is
The side facing the vertical portion 22 with the guide roller 26 in between is precisely provided so as to be parallel to the inner wall of the facing vertical portion 22 at a constant distance of 17 J]. Further, the tip portion 32 is formed into a curved shape like the tip of a knife to facilitate card attachment.

<Operation of the embodiment> The operation of the card holder of the embodiment configured as described above will be explained.

First, as shown in FIG. 3, the card C is moved in the direction of the arrow and mounted on the carrier 8. Since the leading end of the card C follows the leading end 32 of the regulating member 30, the card C is brought to one side of the conveyance table 8. In addition, the horizontal portion 20 is
Guided while being pushed in the direction. FIG. 2 shows this state.

When the card C is completely placed a on the conveyor table 8, a limit switch (not shown) detects this state and sends the card C to the feed mechanism 10a.
, 10b. As a result, the feed screw 12 rotates, and the mover 14, which is screwed into the feed screw 12, moves on the feed screws 10a and 10b.

As the mover 14 moves, the conveyor table 8 to be linked moves on the base 2. At this time, the two sides in the longitudinal direction of the card C placed a are the regulating member 30 and the vertical part 2.
