Abstract

PURPOSE:To realize an information medium processor with a simple and inexpensive medium discharge mechanism by detecting a prescribed loading position so as to obtain a discharge timing up to a prescribed discharge position of a drive means thereby stopping the discharge operation of an information medium. CONSTITUTION:When a control signal 1 received from a switch 11 is active (at a low level), a control circuit 5 starts the drive of an eject motor 7 via a control signal 2 and a motor drive circuit 6. When a cassette guide 8 leaves a prescribed loading position, the output signal 3 of a cassette detection switch 9 goes to a high level. Then a signal 4 drive the eject motor 7 via a delay circuit 10 to part the cassette guide 8 from the loading position of the medium, to raise the guide after a required (sufficient) time when the guide rises up to a prescribed eject position and to stop the drive of the eject motor 7, that is, the rising of the cassette guide 8 for the ejection of the medium. Thus, the processor constitution is made simple and inexpensive.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information medium processing apparatus, and particularly to an information medium processing apparatus having a mechanism for loading and ejecting an information medium of a predetermined recording/reproducing method.

[Prior Art] Conventionally, in an information medium processing device using an information medium (hereinafter simply referred to as a medium) such as a 3.5-inch floppy disk, a configuration in which the medium is loaded and ejected using power such as a motor has been known. It is being

In the figure, reference numeral 8 denotes a cassette guide for loading/unloading a cassette of a medium (not shown, such as a 3 or 5-inch FD) into the drive mechanism of the information medium processing device. ), it rises like an arrow due to the power of the eject motor and ejects the media.

The eject motor 7 is driven by a motor drive circuit 6 consisting of driver elements and the like. The motor drive circuit 6 is

controlled via.

When ejecting a medium, the control circuit 5 outputs a control signal 2 and a motor drive circuit 6 when the control signal I input from the switch 11 (or host device, etc.) on the operation surface of the information medium processing device is active. The eject motor 7 is rotated in a predetermined direction via the cassette guide 8.
to eject the media.

In reality, the media is ejected in a direction (usually horizontal) that intersects the driving direction of the cassette guide 8 by a biasing force such as a spring (not shown). The end timing of the ejecting operation is determined by a home position switch 13 provided on the shaft of the eject motor 7 or a part of a drive system (not shown).

FIG. 4 shows the control timing of the ejection operation. The symbols in the figure correspond to the symbols of each signal line in FIG.

In the case of FIG. 4, each signal is active at a low level, and when the signal 1 becomes low level, the control circuit 5 changes the control signal 2 to a low level in response to this, and starts the eject motor 7. In response to the operation of the eject motor 7, the home position switch 13 provided in a part of the drive system outputs a signal as shown in FIG. The output signal 12 rises to high level. At this timing, the control circuit 5 sets the control signal to a high level and stops driving the eject motor 7.

[Problem to be Solved by the Invention 1] As described above, in the conventional method of controlling the media ejection using the power of a motor or the like, there is a problem in that the timing to stop the media ejection drive is determined.

In view of the above problems, an object of the present invention is to provide an information medium processing device having a simple and inexpensive medium ejection mechanism.

Means for Solving Problem L J In order to solve the above problems, the present invention provides an information medium processing apparatus having a mechanism for loading and ejecting an information medium of a predetermined recording/reproducing method. a drive means for moving the information medium between a mounting position and an ejection position; a means for detecting mounting of the information medium at a predetermined mounting position by the drive means; and a means for processing the output of the detection means; A configuration is adopted in which a control means is provided to obtain a timing for ejecting the information medium to a predetermined ejection position and to stop the ejection operation of the information medium by the drive means at this timing.

[Operation] According to the above configuration, the timing for stopping the ejection operation of the driving means can be determined by using the means for detecting attachment of the information medium to a predetermined attachment position, which is always required in the information medium processing apparatus.

[Example] The present invention will be described in detail below based on an example shown in one drawing.

FIG. 1 shows the configuration of a media ejecting mechanism of an information media processing device employing the present invention. In FIG. 1, the same or corresponding members as in FIG. 3 are given the same reference numerals.

The difference between Fig. 1 and Fig. 3 is that instead of providing a dedicated switch to determine the timing to stop the media ejection operation,
The point is that a cassette detection switch 9 is used. Other hardware includes the output signal 3 of the cassette detection switch 9.
The circuit is the same as FIG. 3 except for the delay circuit IO that delays .

The cassette detection switch 9 is operated by a mounting mechanism (not shown).
It outputs a low level when the cassette guide 8 has descended to a predetermined mounting position, and is always required in an information medium processing device to confirm the mounting of a medium.

In this embodiment, the output signal 3 of the cassette detection switch 9 is delayed for a predetermined period of time by a delay circuit 1O, thereby generating a signal 4 having the same rise timing as the signal 12 in FIG.

The delay circuit 10 is composed of a mono multi-by-break, etc., and is configured to wait for a predetermined time (in this case, necessary (sufficient) time for the cassette guide 8 to move away from the media mounting position and rise to a predetermined ejection position by driving the eject motor. time), delaying the positive edges of the input signal. The delay time of the delay circuit 10 may be adjusted as appropriate depending on conditions such as the speed of the eject motor 7 and the drive system, and the moving distance of the cassette guide 8.

With this configuration, the media ejection operation in the configuration of FIG. 1 is controlled as shown in FIG. 2.

That is, when the control signal 1 inputted from the switch 11 (or host device, etc.) becomes active (low level) as in the conventional example, the control circuit 5 outputs the eject motor via the control signal 2 and the motor drive circuit 6. Start driving. Then, when the cassette guide 8 leaves the predetermined mounting position, the output signal 3 of the cassette detection switch 9 becomes high level.

Thereafter, after the delay of the delay circuit IO, the signal 4 is output as shown in the figure after a necessary (sufficient) time for the cassette guide 8 to move away from the media mounting position and rise to the predetermined ejection position by driving the eject motor. Then, the driving of the eject motor 7, that is, the raising of the cassette guide 8 for media ejection is stopped.

According to the above configuration, the cassette detection switch, which is always required, can be used as a home position switch for detecting media ejection, so the number of switches in the information media processing device can be reduced, and the number of switches in the information media processing device can be reduced. The structure can be made simple and inexpensive, and since the number of switches as mechanical parts is reduced, the reliability of the device can be greatly improved.

Note that when the control circuit 5 is composed of a microprocessor or a gate array, the delay circuit IO can be absorbed into an element in the control circuit 5, so in most cases, the delay circuit IO can be absorbed into an element in the control circuit 5. Therefore, it is considered that there is no need to add a delay circuit IO.

In the above, we assumed a 3.5-inch floppy disk as the media, but it goes without saying that a similar configuration can be implemented for optical disks such as compact disks, or magneto-optical disk devices that utilize a similar ejection mechanism. .

[Effects of the Invention] As is clear from the above, according to the present invention, in an information medium processing apparatus having a mechanism for loading and ejecting an information medium of a predetermined recording/reproducing method, the information medium is loaded at the loading position 1ti.
5 and an ejection position; a means for detecting attachment of the information medium to a predetermined attachment position by the drive means; and a means for processing the output of the detection means; Since the configuration includes a control means that obtains a timing for ejecting the information medium to a predetermined ejection position and stops the ejection operation of the information medium by the drive means at this timing, it is necessary for an information medium processing apparatus. By using means for detecting attachment of the information medium to a predetermined attachment position, the timing for stopping the ejection operation of the drive means can be determined, the number of parts of the apparatus can be reduced, and the configuration of the apparatus can be made simple and inexpensive. Furthermore, since the number of switches as mechanical components is reduced, the reliability of the device can be greatly improved.
