Abstract

PURPOSE:To automatically fix a carriage by only detaching a medium by connecting a loading mechanism and the carriage by a belt passing through an intermediation member, and allowing the carriage to abut with a stopper by the belt at the time of unloading. CONSTITUTION:Pillars 11, 11 are erected at proper positions in front of the rear side of a base 12, and a round bar 10 is supported horizontally at both its ends by these pillars, and belt clamps 9A, 9B are provided respectively at the loading mechanism 2 and the rear side end of the carriage, and both the ends of the belt 6 hung around the round bar 10 are fixed respectively to the loading mechanism 2 and the carriage 6 by the belt clamps 9A, 9B. The belt is made as long as the belt 8 is tensed through the round bar 10 when the loading mechanism 2 is located at an unloading position, and the carriage 5 is pulled strongly to the rear side and strikes the rear stopper 6. Thus, when the medium 3 is unloaded, the carriage 5 is fixed automatically as being in contact with and pressed to the rear stopper 6.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a medium exchange type data recording/reproducing device, and particularly to a carriage fixing structure.

(Prior Art) In a medium exchange type data recording/reproducing device, the carriage has conventionally been fixed in order to prevent the head and carriage from being damaged due to vibrations, shocks, etc. when the W mounting is moved. The following two methods have been conventionally implemented as this type of carriage fixing method. In the first method, nothing in particular is installed in the apparatus itself, but a carriage fixing device made of a plate-shaped body having approximately the same shape as the medium is prepared separately, and this is loaded in place of the medium. This carriage fixing device has a protrusion formed on the plate surface or an arm that can protrude and retract from the plate surface, and when loaded, the carriage is held down and fixed by the protrusion or arm. In the second method, a solenoid is provided in the device, the carriage is fixed when the power is turned off, and when the power is turned on, the solenoid operates to release the fixation.

(Problem to be solved by the invention) However, when using a carriage fixing device, it is necessary to remove it and store it during operation, so a storage space must be secured, and since it is not used frequently, there is no need to lose it. Management becomes complicated.

Furthermore, the carriage fixing device must be set each time it is moved, which is cumbersome, and it is easy to forget to set it.

Further, when a solenoid is used, there is a problem that power is wasted because the solenoid is activated during operation.

The present invention has been made in view of such conventional problems, and its purpose is to provide a medium exchange type data recording and reproducing device that is built into the device and has a carriage fixing structure that does not consume power. It is in.

(Means for Solving the Problems) In order to achieve the above object, the medium exchange type data recording and reproducing apparatus of the present invention has the following configuration.

That is, the medium exchange type data recording and reproducing apparatus of the present invention has five components: a loading mechanism that loads and unloads a medium onto a spindle motor that rotationally drives the medium; and a carriage that moves a head that records and reproduces data on the medium along the surface of the medium. and;
The first and second sections regulate the movement range of this carriage.
In a medium exchange type data recording and reproducing apparatus, the medium exchange type data recording and reproducing apparatus includes: a stopper; and a relay member; one end is fixed to the carriage, the other end is fixed to the loading mechanism via the relay member, and the loading mechanism is in an unloading position. a belt that is tensioned via a relay member and presses the carriage against either the first or second stopper;
It is characterized by having the following.

(Function) Next, the function of the medium exchange type data recording and reproducing apparatus of the present invention configured as described above will be explained.

In the present invention, when the loading mechanism is in the unloading position, that is, when the medium is taken out from the apparatus, the carriage 7 is pressed against the stopper 11 by the belt, and is immovably fixed in this state. Of course, when the loading mechanism is in the loading position, the belt is slack and the carriage is not restrained.

Thus, according to the present invention, the carriage can be automatically fixed simply by taking out the medium, without wasting power.

(Example) Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 and 2 are external views of a medium exchange type data recording and reproducing device mainly showing a carriage fixing structure according to an embodiment of the present invention, FIG. 1 shows the state at the time of unloading, and FIG. indicates loading time.

As is well known, a medium exchange type data recording/reproducing apparatus basically includes a spindle motor 1, a loading mechanism 2, a carriage 5 on which a head 4 is placed, a rear stopper 6, a front stopper 7, and the like.

The loading machine $112 is controlled to move vertically and horizontally by a drive source (not shown), and loads the medium 3 onto the spindle motor 1 (Fig. 2) and unloads it from the spindle motor 1 (Fig. 1). .

A spindle motor 1 is fixed on a base 12, and rotates when a medium 3 is loaded by a loading mechanism 2. The head 4 reads data on the rotating medium 3, and conversely writes data on the medium 3.The carriage 5 carries the head 4 and moves on the base 12, moving the head 4 relative to the medium 3. Let's do it too. The rear stopper 6 determines the movable range of the carriage 5 on the rear side, and the front stopper 7 determines the movable range of the carriage 5 on the front side.

In such a medium exchange type data recording/reproducing device, in this embodiment, a support 1 is provided at an appropriate position in front of the rear side of the base 12.
1 and 11 are erected to horizontally support both ends of the round bar 10, and belt stops 9A and 9B are provided at the rear ends of the load mechanism 2 and carriage 5, respectively, and the belts are hooked onto the round bar 10. Both ends of the belt 8 are fixed to the loading machine 12 and the carriage 5 with corresponding belt fasteners (9A, 9B), respectively.As shown in FIG. When in the load position, the belt 8 is long enough to pass through the round bar 10 and the carriage 5 is strongly pulled toward the rear side and hits the rear stopper 6.

In this way, when the medium 3 is unloaded, the carriage 5 is automatically brought into contact with and pressed against the rear stopper 6 and fixed.

Note that when loading the medium 3, as shown in FIG. 2, the loading machine n42 descends from the unloading position while moving horizontally to the rear side, which loosens the belt 8 and allows the carriage 5 to move. .

Here, in addition to the modes of movement of the load mechanism described above, there are also modes of movement only in the vertical direction or only in the rear/front direction, but it goes without saying that these can be similarly applied.

<Effects of the Invention> As explained above, according to the medium exchange type data recording and reproducing apparatus of the present invention, focusing on the presence of a stopper that regulates the moving range of the carriage, a relay member is used to connect the loading mechanism and the carriage. They are connected by a belt that passes through the media, and when unloading, the belt brings the carriage into contact with the stopper and maintains that state, so the carriage can be automatically fixed just by removing the media, eliminating the complexity of the conventional method. It is possible to provide a medium exchange type data recording and reproducing device that is built-in and has a carriage fixing structure that does not consume unnecessary power.
