Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an eject device that is provided in a tape recorder device or the like and ejects a recording medium such as a cassette tape.

[0002]

[Prior art]

 For example, in a tape recorder device, a cassette tape is used as a recording medium to record or reproduce information, and the cassette tape after the recording or reproduction is completed is ejected to the outside of the tape recorder device. Therefore, the tape recorder device is equipped with an eject device. It is desirable that the eject operation be performed reliably for reasons such as protecting the cassette tape.

When a conventional eject device operates an eject button to perform an eject operation and an eject of a cassette tape is completed within a predetermined time from the start of the eject operation, a preset eject completion switch is provided. By turning on, it is possible to determine the completion of the eject. If the eject completion switch is not turned on within the predetermined time from the start of ejection, it is determined that the ejection is not completed.

Here, in the conventional art, when the eject operation is not completed for some reason even after the eject operation, the cassette tape is pulled back into the eject device, and retry is performed up to the set number of times. Has become. In this case, the driving force for ejecting the cassette tape is set to be the same for all times.

[0005]

[Problems to be solved by the device]

 By the way, in the conventional eject device, if the ejecting is not completed for some reason, it is only possible to set the retry of the ejecting operation multiple times with the same driving force, which makes it difficult to reliably perform the ejecting operation. Therefore, there is a problem that the cassette tape is easily damaged.

The present invention has been made in consideration of the above problems, and an object thereof is to provide an ejecting device capable of reliably performing an ejecting operation and eliminating damage to a recording medium such as a cassette tape. It is what

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a mechanism for ejecting a recording medium with a motor or an electromagnetic solenoid, and when the ejection of the recording medium is not completed, the ejecting operation is retried a plurality of times and the ejecting operation is performed a plurality of times. It is characterized by having means for increasing the driving force of the motor or the electromagnetic solenoid at any stage of retrying.

[0008]

[Action]

 According to the configuration of the present invention, when the ejection of the recording medium is not completed, the ejecting operation is retried a plurality of times, and the driving force of the motor or the electromagnetic solenoid is increased at an arbitrary stage of performing the retriing a plurality of times. Since it is set, the eject operation can be surely performed. Therefore, the recording medium such as a cassette tape will not be damaged.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the ejecting device of the present invention. An example in which a cassette tape is used as a recording medium and a motor is used as a driving force generating means for performing an ejecting operation will be described. Reference numeral 1 is a tape detecting means for detecting the insertion of a cassette tape, 2 is an eject detecting means for detecting the completion of ejection of a cassette tape, and 3 is a micro controller constituted by a CPU (central processing unit) for performing the entire control operation. A computer (microcomputer) 4, a motor driver which controls the operation of a loading motor described later based on the control of the microcomputer 3, 5 a loading motor which is controlled by the motor driver 4 to pull in and eject a cassette tape, and 6 It is a motor voltage variable element that adjusts the driving force (torque) for rotating the loading motor 5 under the control of the microcomputer 3.

First, after the cassette tape is inserted into the recording / reproducing apparatus and the predetermined recording or reproducing is completed, when the eject button is operated, the tape detecting means 1 sends an instruction to eject the cassette tape to the microcomputer 3. As a result, the microcomputer 3 controls the motor voltage variable element 6 to supply the predetermined motor voltage V1 to the loading motor 5, and then controls the motor driver 4 to move the loading motor 5 in the cassette tape ejection direction. To start. Next, when the eject completion is not detected by the eject detection means 2 after a preset time has elapsed (after a time-out) or due to a mismatch between the mechanical mechanism and the eject completion switch, the microcomputer 3 Detects this state and controls the motor driver 4 so as to rotate the loading motor 5 in the reverse direction so that the loading motor 5 once returns the cassette tape to the original position.

Then, this time, the microcomputer 3 controls the motor voltage variable element 6 to supply the loading motor 5 with a motor voltage V2 (V2> V1) higher than the previous time, and then the motor driver 4 is operated. Under control, the loading motor 5 is activated again in the cassette tape ejection direction. As a result, when the eject detection means 2 does not detect the completion of the ejection, the microcomputer 3 detects this state, controls the motor driver 4 to rotate the loading motor 5 in the reverse direction again, and again. Return the loading motor 5 to its original position. Next, the microcomputer 3 controls the motor voltage variable element 6 this time to supply the loading motor 5 with a motor voltage V3 (V3> V2) higher than that of the previous time, and then controls the motor driver 4. Then, the loading motor 5 is activated again in the cassette tape ejecting direction. By repeating such an eject operation, the driving force of the loading motor 5 can be increased stepwise, so that the eject operation can be reliably performed. The eject operation ends when the eject detection unit 2 detects that the eject is completed.

FIG. 2 is a flow chart for explaining the operation of this embodiment. In addition, as an example, the number of times n for retrying the eject operation is set to a maximum of three times (n = 3). Based on the pre-installed eject program, first, n = 0 is set in step A, the motor voltage is weakly set in step B, and the loading motor 5 is started in the cassette tape ejecting direction in step C. Subsequently, in step D, it is determined whether or not the ejection is completed, and if YES, the ejection is completed. If NO, the flow proceeds to step E, where it is determined whether a time-out has occurred. If NO, the flow returns to step D, and if YES, the flow advances to step F, where 1 is added to the set number n.

Subsequently, in step G, it is determined whether or not n = 3, and if YES, an eject error occurs. If NO, the flow proceeds to step H, where the loading motor 5 is returned to its original position. Next, in step I, it is determined whether or not n = 1. If YES (n = 1), the flow proceeds to step J, where the motor voltage is set to medium, and then the flow returns to step D. If NO, the flow proceeds to step K 2, where the motor voltage is set to be strong (n = 2), and then the flow returns to step D 1. In the above series of operations, the eject operation ends when the eject completion is detected.

As described above, according to the present embodiment, when the set number of times to retry the eject operation is set in advance and the eject operation is repeated, the motor voltage supplied to the loading motor 5 is gradually increased. Since the driving force for ejecting the cassette tape is increased, the eject operation can be reliably performed. Therefore, the damage given to the cassette tape can be eliminated.

In the present embodiment, an example in which a loading motor is used as a means for generating a driving force for ejecting a cassette tape has been described, but the present invention is not limited to this, and an electromagnetic solenoid may be used. In this case, the driving voltage supplied to the electromagnetic solenoid is adjusted to change the attraction force of the plunger, so that the same operation as in the case of the motor can be performed. It should be noted that the voltage supplied to the motor or the electromagnetic solenoid does not have to be increased each time it is retried, and the voltage may be increased by retrying twice, for example, or may be increased at other times. In the embodiment, a cassette tape is described as an example of the recording medium, but the present invention is not limited to this and can be applied to a disk. In this case, the disc may be stored in the case or may be left bare. Further, the recording device is not limited to the tape recorder device as long as it is a device to which the recording medium is applied.

Since the ejecting operation can be reliably performed, the damage to the recording medium can be eliminated.
