Abstract

PURPOSE:To realize a tape recorder excellent in operability by discriminating the operating state of an operation button by a discrimination means so as to select a temporary stop state and a complete stop state. CONSTITUTION:A switch 4 in press contact with a stop rod 8 in the sliding direction of the stop rod 8 releasing the engagement between a play rod 6 and a lock rod 7 is arranged and the switch 4 is depressed before the still part of the stop rod 8 moves the lock rod 7 to open the power supply circuit of a motor 5 and to stop the motor thereby forming a temporary stop state. While the stop rod 8 is pushed to the end, the engagement with the play rod 6 is released to form the complete stop state. Thus, the operability is improved with simple constitution by the discrimination means by the play rod 6, the lock rod 7 and the stop rod 8.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a tape recorder in which a single button operation serves as both a pause operation and a stop operation.

BACKGROUND OF THE INVENTION In recent years, tape recorders are often used to take notes during meetings, interviews, etc., and it is desired that the tape recorder has an easy-to-operate pause function when recording, playing, and writing. On the other hand, the number of parts is being reduced in order to reduce costs.

To explain conventional tape recorders below, a pause button is provided separately from a normal stop button, and when the pause button is pressed once during playback (or recording), the magnetic tape stops running. Press again to play (
or recording) was configured to start. Also, some tape recorders without a recording function did not have a pause function.

Problems to be Solved by the Invention However, with the above configuration, separate buttons are required for pausing and stopping, which increases the number of parts, and furthermore, the buttons must be pressed separately when pausing and when canceling pausing. This method requires manual operation and has the problem of poor operability.

In view of the above problems, the present invention provides a tape recorder with a simple component structure and good operability.Means for Solving the ProblemsIn order to solve the above problems, the tape recorder of the present invention has
An operation button that serves as both a stop operation and a temporary stop operation, a temporary stop means and a stop means that are activated in response to the operation of this operation button, and a control button that determines whether or not the operation of the operation button exceeds a predetermined set value. The present invention is characterized by comprising a discriminating means for determining the above-mentioned temporary stopping means and operating the above-mentioned stopping means according to the determined result.

Effects of the present invention With the above-described configuration, the discriminating means can distinguish between a temporary stop state and a complete stop state depending on the operation status of the operation button, and a single operation button can be used for both temporary stop and stop with a simple configuration. It is possible to improve operability and reduce costs.

Embodiment Hereinafter, a tape recorder according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a completely stopped state of a tape recorder in an embodiment of the present invention. 6 is a play rod on which the magnetic head 1 and pinch roller 2 are mounted; 4 is a switch for opening and closing the power supply circuit of the motor 6; A is engaged with the play rod 6 to hold the pinch row 22 in pressure contact with the capstan shaft 1o; A lock rod 11 has a capstan shaft 1o for feeding the magnetic tape, a flywheel is driven by a motor 5 via a belt 3, and a stop rod 8 connects the lock rod 7 and the play rod e. It has a slope for moving the lock rod 7 in the direction of disengaging the engagement, and a surface for pressing the switch. A lock spring 9 biases the lock rod 7 in the direction of engagement with the play rod 6, and also applies a bias force to the stop rod 8 in the opposite direction to its pushing direction. Reference numeral 12 denotes a play spring that acts on the play rods in a direction to prevent the pinch roller 2 from coming into contact with the capstan shaft 1°.

The operation of the tape recorder configured as described above will be described below with reference to FIGS. 1, 2, 3, and 4.

First, FIG. 1 shows a completely stopped state. In this state, the motor 6 does not rotate, and the capstan shaft 10 and pinch row 2
2 is far away.

FIG. 2 shows the playback (or recording) state. play rod 6
is pushed in, and in conjunction with this, the pinch row 22 comes into pressure contact with the capstan shaft 10, the motor 6 rotates, the flywheel 11 rotates via the belt 3, and the magnetic tape is fed. This is the playback (or recording) state. A lock pawl 6& provided on the play rod 6 engages with the lock rod 7, and the lock rod 7 is maintained in order to receive the biasing force of the lock spring 9.

FIG. 3 shows a state in which the stop rod 8 is pushed in halfway; in this state, the inclined portion 8a of the stop rod 8 does not act to move the lock rod 7 against the biasing force of the lock spring 9; Pleikutsudoro remains held in the lock rod. On the other hand, the switch 4 is pressed by the stop rod 8, the power supply circuit of the motor is opened, the rotation of the motor is stopped, and the magnetic tape is not fed. In this state, a pause state is obtained.

FIG. 4 shows the state in which the stop rod 8 is pushed to the end υ, and the lock rod 7 is moved against the biasing force of the lock spring 9 by the inclined portion 8a of the stop rod 8, so that
The engagement with the play rod e is disengaged, resulting in a completely stopped state as shown in FIG.

Figures S to D show the relationships among the play rod 6, lock rod 7, and stop rod 8 during stop, playback (or recording), pause, and mid-stop from playback. When the operating force on the stop rod 8 is released from the paused state shown in FIG. Restart energizing the motor from the power circuit. Therefore, the playback (or recording) state is immediately returned from the paused state.

As described above, according to this embodiment, the switch 4 that comes into contact with the stop rod 8 is disposed in the sliding direction of the stop rod 8 that releases the engagement between the play rod 6 and the lock rod 7, and the inclined portion of the stop rod 8 is By pressing the switch 4 and opening the power circuit of the motor 5 to stop the motor before moving the lock rod 7, a temporary stop state can be created.

In the above embodiment, a mechanism was explained in which the pause and stop states are determined based on the amount of push of the stop rod 8. However, if a microprocessor is used in other ways, it may be possible to It can also be configured to determine each state of pause and stop with continuity. In this case, if the stop button is continuously operated within a predetermined time, it will be paused, and if the stop button is not continuously operated within the predetermined time and is a one-off operation, it will be stopped. It is necessary to load into the microprocessor a step for determining that there is. Then, when the stop button is released from the paused state, it is preferable to return to the playback (or recording) state.

Effects of the Invention As described above, in the present invention, the discriminating means can discriminate the operation status of the operation button and select between the temporary stop state and the complete stop state, and it is possible to realize a tape recorder with good operability. .
