Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a portable, compact and lightweight tape recorder, a so-called headphone stereo type tape recorder.

(b) Prior Art In general, such tape recorders are very popular among young people because they are carried around, for example, by being hung from the user's waist, and can easily enjoy music even outdoors.

On the other hand, similar to tape recorders, pedometers that are carried along with users have begun to spread widely across the market regardless of the user's age due to growing interest in health. People have also been seen carrying both music meters and enjoying music while taking a short break in the park while walking or jogging.

(c) Purpose of the invention The present invention has been developed in view of these points, and is a portable, compact and lightweight tape recorder with a new pedometer function added to it to meet a wide range of uses by users. It was made possible.

(d) Structure of the invention In other words, in order to achieve the above object, the present invention is a portable, compact and lightweight tape recorder which amplifies the playback signal from the magnetic head and then connects it to the headphone jack section or speaker section. a selection switch for switching between normal tape recorder use and pedometer use; and a selection switch that uses the amplifier when the selection switch is switched to use the pedometer, and synchronizes with the up and down movement when carrying. The oscillation circuit is provided with an oscillation circuit that repeats intermittent oscillation, and a counter circuit that counts the number of intermittent oscillations of the oscillation circuit.

(E) Embodiment An embodiment of the present invention will be described below with reference to the drawings.

That is, in the figure, 1 is a magnetic head, 2 is a preamplifier, 3 is a selection switch for switching between tape recorder use and pedometer use, 4 is a variable resistor, 5 is a main amplifier, 6 is a speaker, 7, 8, 9 is a resistor, a capacitor, and a coil that together with the main amplifier 5 constitute an oscillation circuit 10 when the selection switch 3 is switched to the second contact 3b side for use with a pedometer. Reference numeral 11 denotes a support arm having one end rotatably supported by a shaft 12 on the side of the tape recorder main body and a magnet 13 fixed to the other end.
1 is suspended by a coil spring 14 so that a magnet 13 moves up and down in response to the user's up and down movement. Reference numeral 15 denotes a reed switch which can be turned on and off repeatedly according to the vertical movement of the magnet 13, and the reed switch 15 causes the oscillation circuit 10 to oscillate intermittently. 16 is a counter circuit that counts the number of intermittent oscillations of the oscillation circuit 10 , and 17 is a display circuit that displays the count value of the counter circuit 16.

Therefore, when the selection switch 3 is switched to the first contact 3a side for use with a tape recorder, the reproduced signal from the magnetic head 1 is amplified through the amplifier 2 and the main amplifier 5 and then output to the speaker section 6. It will operate as a normal tape recorder.

Next, when the selection switch 3 is switched to the second contact 3b side that uses a pedometer, the resistor 18 → selection switch 3 → variable resistor 4 → main amplifier 5 → coil 9 → capacitor 8 → resistor An oscillation circuit 10 is constructed by the loop of 7, and the oscillation with a resonance frequency of 0 determined by the capacitor 8 and coil 9 of the oscillation circuit ₁₀ is caused by the activation of the reed switch 15 according to the vertical movement of the user while jogging. It will repeat intermittent ON-OFF. Therefore, by counting the number of intermittent oscillations using the counter circuit 16 and displaying the counted value on the display circuit 17, it is possible to know the number of steps taken by the user while jogging.

If the counting method of the counter circuit 16 is modified in various ways, it is possible to know the number of steps per minute and the number of steps corresponding to each terrain.

(f) Effects of the invention As mentioned above, according to the invention, a pedometer function is newly added to a portable, small and lightweight tape recorder, and users can freely choose between using a normal tape recorder and using a pedometer. This allows it to meet a wide range of user needs. Furthermore, according to the present invention, a part of the existing tape recorder circuit is also used and a new pedometer function is added, making it possible to reduce the number of parts and cost.
