Abstract

A first transmitter 10 having a first antenna 11 and a power supply part 12, and a second transmitter 20 having a second antenna 21 and a transmitter circuit 22 are provided. The first transmitter 10 and the second transmitter 20 are brought to the state of being connected, and the power supply part 12 of the first transmitter drives the transmitter circuit 22 of the second transmitter 20. Transmission output from the transmitter circuit 22 is simultaneously transmitted from the first antenna 11 provided in the first transmitter 10 and from the second antenna 21 provided in the second transmitter 20. Accordingly, sufficient intensity of transmission radio field is assured. Furthermore, with the configuration where a transmission is made in condition where an instrument and a device for transmitting data are being connected, a favorable transmission can be established even when the radio field intensity is degraded due to a contact by a user.

Claims

1. A transmission system comprising,

a first transmitter having a first antenna and

a second transmitter having a second antenna, wherein,

said first transmitter further comprises a power supply part,

said second transmitter comprises a transmitter circuit which outputs identical information as a transmission signal to said first antenna and said second antenna,

said second transmitter is attachable to and detachable from said first transmitter, and

in a state where said first transmitter and said second transmitter are connected, said second transmitter is connected to said power supply part, and said first antenna and said second antenna simultaneously transmit said identical information.

3. The transmission system according to claim 1, wherein,

said first transmitter comprises an operating means which conducts a transmitting operation, and radio field intensity outputted from said first antenna is set higher than the radio field intensity outputted from said second antenna.

4. The transmission system according to either of claim 1 and claim 3, wherein,

said first antenna and/or said second antenna is a loop antenna.

6. The transmission system according to claim 1, wherein,

said first antenna has a biometric function to measure biometric information, and said identical information is said biometric information.

7. The transmission system according to claim 6, wherein,

said second transmitter is connected to each of multiple measuring machines to measure biometric information which is different from the information of said first transmitter, and the biometric information measured by said measuring machines being connected is transmitted from said second antenna.

8. The transmission system according to either of claim 6 and claim 7, wherein,

said biometric information is the number of steps.
