Means for Solving the Problems In order to achieve the above object, the present invention provides a first sensor for detecting that a user can attach and detach a tape cassette to and from a cassette loading device, and a tape cassette for running a tape. When the user continuously presses the operation button a plurality of times during a period in which neither the second sensor that detects the stationary state of the device nor the first sensor and the second sensor detects the target state, the operation button is Each time is pressed, the feeding / discharging operation direction of the tape cassette is reversed, and the user presses the operation button while either the first sensor or the second sensor detects the target state. It is provided with a logical operation device which is made effective only once at the first time when it is continuously pressed a plurality of times, and which performs a feeding operation or a discharging operation of the tape cassette.

Action The action of the present invention by the above means is as follows. If the user presses the operation button once or a plurality of times continuously during the feeding / discharging operation, and if both the first sensor and the second sensor are in the non-detection state, the logical operation device will It is possible to reverse the input / output operation direction and provide a quick response to the user. Further, at this time, if either the first sensor or the second sensor is in the detection state, the logical operation device invalidates the operation button that is continuously pressed a plurality of times.
The first intended operation can be performed quickly.

Example Hereinafter, a magnetic recording / reproducing apparatus of an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of the present invention, in which 11 is a cassette loading device for placing the tape cassette on a tape running device, and 12 is a state in which the cassette loading device 11 can externally attach and detach the tape cassette. This is a first sensor for detecting that the tape loading device 11 is a second sensor for detecting that the cassette loading device 11 has placed the tape cassette on the tape running device. Reference numeral 15 is an operation button for allowing the user to insert and eject the tape cassette for magnetic recording and reproduction.

14 is a command from the operation button 15, the first sensor 12 and the second sensor
It is a logical operation device that drives and controls the cassette loading device 11 according to the output state of 13.

FIG. 2 is a main part flowchart showing the operation of the embodiment of FIG. 1, and the operation will be described below.

In step 1, depending on the output states of the first sensor 12 and the second sensor 13, if the tape cassette has been ejected from the magnetic recording / reproducing apparatus, the process proceeds to step 2, and if it has already been placed in the tape running apparatus. Go to step 10. When the operation button 15 is pressed in step 2, the process proceeds to step 3,
The cassette loading device 11 is driven to start the tape cassette feeding operation. In step 4, it waits until the cassette loading device 11 is no longer in the ejection completed state. In step 5, when the user presses the operation button 15 again in order to eject the tape cassette during the feeding operation, the process proceeds to step 10 to reversely drive the cassette loading device 11 and eject the tape cassette. In step 6, the second sensor 13
When the cassette loading device 11 detects that the tape cassette has been completely set in the tape running device from the output state, the process proceeds to step 7 and steps 5 and 6 are repeated until the completion of the setting is detected. In step 7, the driving of the cassette loading device 11 is stopped, a series of tape cassette feeding processing is completed, and tape loading processing for winding the tape around the head cylinder is performed.

On the other hand, when it is detected in step 10 that the operation button 15 has been pressed, the process proceeds to step 11, and after the tape unloading process for storing the tape in the cassette half, the cassette loading device 11 is driven in the ejecting direction, Start the cassette ejection operation. In step 12, the cassette loading device 11 waits until it is not in the feeding completion state. In step 13, when the user presses the operation button 15 in order to re-feed the tape cassette which is being ejected, step 3
Then, the cassette loading device 11 is reversely driven to feed the tape cassette. In step 14, if it is detected by the output state of the sensor 12 that the cassette loading device 11 has completed ejecting the tape cassette, the process proceeds to step 15 and steps 13 and 13 are executed until ejection completion is detected.
Repeat 14. In step 15, the driving of the cassette loading device 11 is stopped, and a series of tape cassette ejection processing is ended.

Therefore, according to this embodiment, the user can immediately eject the tape cassette being supplied to the magnetic recording / reproducing apparatus by pressing the operation button, and the tape cassette being ejected can be operated similarly. You can recharge immediately by pressing the button. Also, when the tape loading device is in the discharging completion state or the feeding completion state,
