Abstract

A caliper unit has a connector having connecting terminals. The caliper unit measures a value of a product, and generates digital data representing this value. A data-transmitting apparatus has a housing. The housing can be attached to caliper unit. The housing has a fastening ring and a connecting plug. The plug can be connected to the connector of the caliper unit by the fastening ring. A microcomputer including a CPU is provided within the housing. A RAM is also provided within the housing, for storing the digital data input from the caliper unit and also an identification (ID) number assigned to the data-transmitting apparatus. The microcomputer forms a serial-data message from the digital data and the ID number, both stored in the RAM. A transmitter is provided within the housing, for transmitting the serial-data message in the form of a radio message.

Claims

1. A data-transmitting apparatus which is connectable to digital output terminal of a digital measuring means for outputting a digital measured value, said digital measuring means including said digital output terminal, said data transmitting apparatus comprising:

housing means detachably mounted to the digital measuring means;

connecting plug means provided on said housing means for connecting with the digital measuring means digital output terminal and for receiving digital data output from the digital output terminal of the digital measuring means;

ID number setting means for storing at least one digit of desired digital data supplied from the digital measuring means through the connecting plug means as an ID number for identifying the data-transmitting apparatus;

microcomputer means provided with said housing means and coupled to said ID number setting means, for generating a serial measured data message including the digital data supplied from the digital measuring means through the connecting plug means as a measured result of the digital measuring means; and

data transmitter means provided within said housing means and connected to said microcomputer means, for modulating an RF carrier signal with the serial measured data message formed in said microcomputer means and for radiating said modulated RF carrier signal to an external apparatus in the form of a radio message.

2. A data-transmitting apparatus according to claim 1, wherein said ID number setting means includes reading means for reading one of a one digit numeral and a two digit numeral of digital data supplied from the digital measuring apparatus through said connecting plug, and storing means for storing the numeral read by said reading means as an ID number.

3. A data-transmitting apparatus according to claim 2, wherein said data transmitter means includes a switching means connected to said reading means responsive to digital data output from the digital measuring means for causing said reading means to perform the reading operation.

4. A data-transmitting apparatus according to claim 1, wherein said ID number setting means includes reading means for reading at least the upper one-digit numeral corresponding to the digital data supplied from the digital measuring apparatus through said connecting plug, and storing means for storing the numeral read by said reading means as the ID number.

5. A data-transmitting apparatus which is connectable to digital output terminal of a digital measuring means for outputting a digital measured value, said digital measuring means including said digital output terminal, said data transmitting apparatus comprising:

housing means detachably mounted to the digital measuring means;

connecting plug means provided on said housing means for connecting with the digital measuring means digital output terminal and for receiving digital data output from the digital output terminal of the digital measuring means;

ID number setting means for storing at least one digit of desired digital data supplied from the digital measuring means through the connecting plug means as an ID number for identifying the data-transmitting apparatus;

microcomputer means provided with said housing means, for generating a serial measured data message including both (a) the digital data supplied from the digital measuring means through the connecting plug means as a measured result of the digital measuring means, and (b) the ID number; and

data transmitter means provided within said housing means and connected to said microcomputer means, for modulating an RF carrier signal with the serial measured data message formed in said microcomputer means to an external apparatus in the form of a radio message.

6. A data-transmitting apparatus according to claim 5 wherein said ID number setting means includes reading means for reading one of a one-digit numeral and a two-digit numeral of digital data supplied from the digital measuring apparatus through said connecting plug, and storing means for storing the numeral read by said reading means as an ID number.

7. A data-transmitting apparatus according to claim 5, wherein said data transmitter means includes switching means which is operated when digital data is output from the digital measuring apparatus, and said reading means performs the reading operating when said switching means is operated.
