Abstract

PURPOSE:To prevent malfunction, by blocking the changeover from the recording state to a program search operation, through the operation of a selection circuit, in performing each operation such as fast feeding through the operation of a tape program search operating button. CONSTITUTION:At the reproduction state of a tape recorder, when a tape program search operating button 13 is operated and an adjusting knob 15 is touched, a tape running control means 14 is operated, a signal is applied to a control circuit 7 through the operation button 13 and a selection circuit 19 to release the reproducing state of the tape recorder. The operation is moved to the set state such as the fast feeding through the adjustment of the knob 15. When the tape program search is operated at the recording state, the application of a control signal from a tape running control means 14 to the control circuit 7 and the voltage detection circuit 13 is blocked at the selection circuit 19 and the tape recorder continues the recording operation.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus that can easily locate a desired position on a tape.

Generally, the method of finding the desired position on the tape is to perform fast-forwarding and rewinding operations while looking at the scale on the counter provided in the tape recorder. Because of the fast speed, it is difficult to distinguish the scale of the first digit of the counter, and therefore, it is necessary to repeat such fast-forwarding and rewinding operations two or three times, which is inconvenient.

Also, a device has been developed in which a switch is provided on the counter, and when the scale of the counter reaches a predetermined value, the switch cancels the fast forwarding or rewinding operation, but in such a device, the counter does not indicate the predetermined scale. Since it is designed to operate only occasionally, if there are several desired parts, it is necessary to perform the above-mentioned operation, which is inconvenient.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a device that can extremely easily find a desired portion of a tape.

An embodiment of the present invention will be described in detail below with reference to the drawings.

In the same figure, (1), (2), (3), (4), (5) and (6) are respectively recording, playback, rewind, fast forward, pause F, and stop operation buttons, (7 ) is a control circuit that switches the operating state of the tape recorder in accordance with each operation, (8) is a plunger that operates to suck during playback operation and puts the tape recorder into playback mode, and (9) is a capstan that rotationally drives the capstan. (10) is a reel electric motor that rotationally drives the rewinding and take-up reel shafts, (1υ is a rotation direction control circuit that controls the rotation direction of the reel electric motor aω, (121 is a rotation direction control circuit of the reel electric motor aω) This is a rotational speed control circuit that controls the speed. (131 is a tape positioning operation button that is operated during tape positioning operation, and the center is the positioning operation button! When 131 is operated, it becomes operational. This is a tape running control means. (15) is a variable resistor that is variable by the tape running control means (adjustment heir constituting the adjustment heir, (1G) is a variable resistor that is variable by the adjustment heir 1)5), and a positive - Negative pressure is applied to both sides, and the midpoint thereof is grounded. (17) detects the voltage guided by the slider of the variable resistor (16) and adjusts the rotational speed of the reel motor (1). and a voltage detection circuit that controls the rotation direction. (
Reference numeral 1□□□ is an induced voltage detection circuit that detects an induced signal from the human body when the user touches the adjusting child f+5), and operates the tape running control means side only during the adjusting operation. (I
9) is a tape running control means (141) in the recording state.
This is a selection circuit that prevents signals from being applied to the control circuit (7) and the voltage detection circuit (1η), and is configured so that the blocking operation is canceled when a temporary stop operation is performed. The circuits are related as shown.

The present invention is constructed as described above, and its operation will be explained next. First, a normal operation in which the tape positioning operation button t131 is not operated will be explained. In this state, since the voltage detection circuit (1η) that controls the rotational speed and rotational direction of the reel electric motor (10) is in the UJ non-operation state, the rotational direction control circuit (11) and the rotational speed control circuit (12 are the control circuit (7). ). From this state, the user can press the recording operation button (1), playback operation button (2), rewind operation button (3), and fast forward operation button (4) as appropriate. When operated, the control circuit (7) performs operations according to each operation, switching the reel electric motor (11), capstan electric motor (9), and plunger (8) to a state suitable for each operation, and each operation of the tape recorder is performed. configured.

Also, if you operate the stop operation button (6) while in any operating state, each operation will be canceled and the tape recorder will return to the stopped state, and if you operate the pause operation button (5) while it is in the recording or playback state. The winding force of the take-up reel shaft is released, and the engagement between the capstan and the pinch roller is released, and the tape recorder is brought to a temporary halt.

Next, the operation when the tape positioning operation button 03) is operated while the tape recorder is in each state will be described.

1. Playback state When the tape recorder is in the playback state, when the tape positioning operation button (opening) is operated, the tape travel control means (b) becomes operational, but does not operate until the user touches the adjustment heir ( ] 51). When the user touches the adjustment heir (151), the tape running control means 4 operates, and the signal is sent to the control circuit (151) through the positioning operation button f13 and the selection circuit +11.
7) K is applied and the playback state of the tape recorder is canceled. Then, when the slider of the variable resistor (1ω) is at the midpoint, its potential becomes zero potential, so the tape is not allowed to run, but comes to a halt.From this state, adjust the adjustment heir port 9 and start sliding. When the child is moved by the positive potential side pressure, the voltage detection circuit (1η) detects the positive potential and the rotation direction control circuit (
11) and the rotational speed control circuit O2 are controlled to fast-forward the tape. When the slider is moved to the negative potential side, the voltage detection circuit (171) detects the negative potential and controls the rotational direction control circuit OI1 and the rotational speed control circuit (171) to rewind the tape. In this state, the running speed of the tape increases as the positive and negative potentials increase toward the positive and negative sides, respectively.Also, no matter where the slider is located, if the user releases his/her hand from the adjusting child (15), the tape will run faster. The recorder returns to playback status.

2 Recording state When the tape positioning operation is performed in the recording state, the application of the control signal from the tape running control means to the control circuit (7) and the voltage detection circuit (13) is made clear by the selection circuit (1ω). and the tape recorder continues recording.

3. Fast-forwarding and rewinding state In this fast-forwarding and rewinding state, when the adjustment heir (151) is operated, a control signal from the tape running control means center is applied to the control circuit (7) and the voltage detection circuit (17), thereby changing the playback state. The operation described in 1. is performed.In this state, when the hand is released from the adjustment child t151, the tape recorder returns to the stopped state.

,4. Stopped state When the adjustment heir (15) is operated in the stopped state, the tape is fast-forwarded or rewound depending on the position of the slider of the variable resistor (16), and when you release your hand from the adjustment heir +151,
, pause state First, in the pause state in the playback state, as described above, the tape is fast-forwarded or rewound in accordance with the operation of the adjustment heir (15), and when the adjustment heir (1ω) is released, the tape returns to the paused state. Also, if you perform a pause operation in the recording state, this operation will cause the selection circuit (
+9) control signal control circuit (7) and voltage detection circuit f
17) is released, and as a result, the tape is fast forwarded or rewound in accordance with the operation of the adjustment knob. When the tape recorder is released from the adjusting child OQ, the tape recorder returns to the paused state, and when the pause operation is released, the recording operation starts from that position.

Incidentally, in this embodiment, the tape running is controlled only while the human body guidance signal obtained from the adjustment child 05) constituting the tape running control means (b) is being detected, but such a function is not necessarily required. It's not what you need.

As explained above, in the present invention, the running of the tape is continuously changed from a fast forward state to a rewind state and from a rewind state to a fast forward state by the tape positioning operation, so that the tape can be positioned at a desired position. Not only can you easily find the information, but it also prevents you from switching to the positioning mode even if you perform the positioning operation from the recording mode, which prevents erroneous operations such as failing to record important information. I can do it.
