CONSTITUTION:The radio receiver of a synthesizer system is used for step number integration control and its display drive device by adding a step number integration counter 14 and an operation entry means 11 sending a count pulse to a microcomputer used for a frequency channel selection and a display driver for the radio receiver of a synthesizer system. A display changeover means 6 is used to select a display device 16 for frequency display or step number integration display optionally. An integrated step number is immediately known even during radio reception by selecting the display changeover means 6 and the small sized radio receiver is used also for a pedometer without increasing its size.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frequency synthesizer type small radio receiver.

[0002]

2. Description of the Related Art Generally, a pedometer forms a unique device, and a small frequency synthesizer type radio receiver is also a unique device form. Therefore, when carrying such a radio receiver, a pedometer was required separately from the radio receiver when measuring the number of steps.

[0003]

However, as described above, it is troublesome to carry two types of equipment, a pedometer and a small frequency synthesizer type radio receiver, and each control circuit and display are required. It had a problem that it was economically uneconomical.

In view of the above-mentioned conventional problems, the present invention has been made for the purpose of providing a pedometer function and a small frequency synthesizer type radio receiving function by a single device.

[0005]

In order to solve the above-mentioned problems, the radio receiver of the present invention has a tuning control means for selecting a frequency synthesizer receiver including a PLL circuit in response to an input from a radio selection operation means. And a display control of the reception frequency on the display by the output from the tuning control means.
Display unit driving means, step number detecting means for detecting the number of steps according to the movement of the human body, step number controlling means for receiving the output from the step number detecting means and controlling the total number of steps, and displaying the total number of steps on the display. Second display driving means for controlling and display switching means for switching the display of the display between the reception frequency and the integrated step count are provided.

[0006]

With the above arrangement, the present invention can be used not only as a display of a radio receiver by switching the display switching means but also as a pedometer and as a pedometer.

[0007]

Embodiments of the radio receiver according to the present invention will be described in detail below with reference to FIGS.

FIG. 1 is a block diagram of a radio receiver according to the first embodiment of the present invention.

In FIG. 1, reference numeral 2 is a frequency synthesizer receiving circuit section 2, and 19 is a PL for determining the receiving frequency.
The reception frequency, that is, the broadcasting station is determined by controlling the frequency division ratio of the programmable frequency divider of the PLL circuit. In response to the operation of the radio selection operation means 5, the tuning control means 17 outputs a control command of the reception frequency to the PLL circuit 19 and a required display command to the display 16.

The tuning control means 17 includes a CPU 13 and a CP.
A PLL control means 12 for controlling the frequency division ratio of the PLL circuit 19 in response to a command from the U13, an operation input means 9 for sending a code signal to the CPU 13 in response to the operation of the radio selection operation means, and a display control of the display device 16 The first display driving means 15a is provided. Radio selection operation means 5
Has a band switch for switching frequency bands of AM band, FM band, and TV band, and a tuning switch composed of an up / down switch for arbitrarily selecting a reception frequency. Further, a power switch for turning the power on and off and other necessary operation switches are provided.

The step count control means 18 counts the number of pulses with the CPU 13 and accumulates and accumulates the pulse count, and the step count integration counter 14 responds to the operation of the step count detection means 7 by sending count pulses to the step count integration counter 14. The input means 11 and the second display driving means 15b for controlling the display of the display 16 are provided.

The step number detecting means 7 mechanically detects the vibration generated according to the movement of the human body, converts it into an electric signal, and at the same time sends it to the operation input means 11.

The display switching means 6 is composed of a scroll system with one key or a slide switch.
A signal is sent to the display switching judging means 10 which instructs the PU 13 to the mode of the display switching means 6. At this time, when the reception frequency display mode is selected, the tuning control means 17 is controlled by the command of the CPU 13 to display the reception frequency on the display 16, and when the step integration display mode is selected, the command of the CPU 13 is selected. Thereby, the step count control means 18 displays the integrated step count in the counter memory 20 in the step count integration counter 14 on the display 16. The counter memory 20 in the step counting counter 14 is constantly renewed by the pulse from the operation input means 11 which sends out a count pulse.

Step count resetting means 8 for clearing the counter memory 20 in the step count integrating counter 14 to zero
When the step number integrated display mode is selected by the display switching means 6 and the integrated step number is displayed on the display 16, the integrated step number in the counter memory 20 is set to zero. At the same time, the step count control means 18 sets the integrated step count display of the display 16 to zero.

The step count detecting means 7 always performs the step count detecting operation, the operation input means 11 sends out a count pulse, and the step count integrating counter 14 keeps counting. The control is performed regardless of the operating state, that is, the pedometer function can be used independently as a pedometer and in combination with the radio reception state.

The tuning control means 17 and the step count control means 1
This embodiment can be realized with a simple configuration by realizing 8 and 1 with one microcomputer.

FIG. 2 is a diagram showing a specific example in which the reception frequency display and the integrated step count display using the LCD are displayed on the same display. Reference numeral 21 is a display using an LCD. When the step count integration display is being performed, the step count integration display mark 22 is displayed to identify the step count integration. Although the step count integrated display mark 22 is displayed in characters in this example, a mark or a symbol that can be used to determine that the step number integration is being performed can be used.

FIG. 3 is a diagram showing a specific example of the received frequency display when FM106.4 MHz is received.

FIG. 4 is a diagram showing a specific example of displaying the total number of steps when walking with 21385 steps. As shown in FIGS. 3 and 4, the same numerical value display segments 23a, 23b, 23
The reception frequency or the integrated number of steps is displayed using c, 23d, and 23e.

Next, FIGS. 5 and 6 show an example of the arrangement of parts. FIG. 5 is a side cross-sectional view when the pedometer is mounted in the space where the speaker was mounted. FIG. 6 is a perspective view of the entire surface when the step detector is attached to the space where the speaker was attached. Reference numeral 25 denotes a device cabinet, and a pedometer count switch 28 which operates as the step count detecting means 7 by means of a mounting rib 24 formed inside the cabinet 25.
Is fixed to the speaker mounting space of the conventional radio receiver with mounting screws 27. With such a configuration, the device can be downsized, and an existing electrical connection method and device cabinet can be used, and the device can be easily attached. Needless to say, the pedometer count switch 28 may be fixed with resin instead of screws.
